PART I
Item 1. Business.
Overview
We are a medical technology company focused on the development and commercialization of innovative, minimally invasive solutions for patients with obstructive sleep apnea ("OSA"). Our proprietary Inspire system is the first FDA, European Union ("EU") Regulation No. 2017/745 ("MDR" or "EU Medical Devices Regulation"), and Japan Pharmaceuticals and Medical Devices Agency-approved neurostimulation technology of its kind that provides a safe and effective treatment for patients with moderate to severe OSA. We have developed a novel, closed-loop solution that continuously monitors a patient’s breathing and delivers mild hypoglossal nerve stimulation to maintain an open airway. A significant body of clinical data, which includes a publication in the New England Journal of Medicine, multiple publications in leading respiratory, ear, nose and throat ("ENT") and sleep medicine journals, and more than 385 peer-reviewed publications, supports the safety and efficacy of Inspire therapy. Inspire therapy received premarket approval ("PMA") from the FDA in 2014 and has been commercially available in certain European markets since 2011. Japan's Ministry of Health, Labour and Welfare ("MLHW") approved Inspire therapy to treat moderate to severe OSA in 2018. Inspire therapy is indicated for patients with moderate to severe OSA who do not have significant central sleep apnea and do not have a complete concentric collapse of the airway at the soft palate level. Physicians have treated more than 125,000 patients with Inspire therapy across the United States ("U.S."), Europe, and Asia.
Sleep apnea is a serious and chronic disease that negatively impacts a patient’s sleep, health, and quality of life. OSA is the most common form of sleep apnea. OSA occurs when a person’s breathing is interrupted during sleep by a partially or completely blocked airway and affects patients of all ages, sexes, and body types. The severity of OSA is measured by the number of partial or complete airway blockages that a patient experiences in an hour, referred to as the apnea-hypopnea index ("AHI"). Moderate OSA patients have an AHI of 15 to 30 events per hour, while severe OSA patients have an AHI of 30 more events per hour. Left untreated, OSA increases the risk of high blood pressure, hypertension, heart failure, stroke, coronary artery disease, and other life-threatening diseases.
Continuous positive airway pressure ("CPAP") is the leading therapy for patients with moderate to severe OSA. CPAP is delivered through a face or nasal mask that connects through a hose to a bedside air pump. In order for CPAP to be most effective, the mask must form an airtight seal on the patient’s face or nose and the mask must be worn every night. The effectiveness of CPAP has been limited by low patient compliance as many patients find the mask or treatment cumbersome, uncomfortable, and loud. When CPAP fails or cannot be tolerated, patients’ remaining treatment options consist primarily of invasive surgical procedures developed to modify or remove existing tissue in an attempt to create free air flow. These invasive surgical procedures have limited or unpredictable clinical benefit, are irreversible, and can be extremely painful.
We believe that there continues to be both an urgent clinical need and a strong market opportunity for an alternative to CPAP that is effective and minimally invasive. Data shows that patients with CPAP intolerant OSA have a higher risk for mortality than patients with CPAP-tolerant OSA and higher healthcare utilization rates based on increased cardiovascular health risks. Two findings published in 2022 from Medicare and the French national healthcare insurance databases have demonstrated, in large national cohorts, risks of CPAP intolerance. Specifically, Medicare patients with CPAP intolerance had higher risks of new cardiovascular events than those who were adherent. Similarly, the French national reimbursement database showed that in over 176,000 patients, CPAP non-adherent patients had a higher risk for mortality and new onset of heart failure than those who were adherent. These findings show the urgency of treating CPAP-intolerant OSA to improve patient outcomes and potentially reduce healthcare utilization.
Inspire therapy is an innovative, closed-loop, minimally invasive solution designed to provide comfort and convenience, and which results in high compliance for patients with moderate to severe OSA. Once implanted, the Inspire system delivers electrical stimulation that causes a slight forward movement of the back of the tongue, which helps to maintain an open airway, enabling the patient to inhale freely without interruption. We believe our Inspire therapy provides the following benefits:
6
•Safe, effective, and durable treatment supported by compelling clinical data, including long-term efficacy results out to five years from initial treatment.
•Closed-loop system that uses a proprietary algorithm to continuously monitor patients’ breathing and provide electrical stimulation during the inspiratory phase.
•Comfortable and convenient therapy resulting in high patient satisfaction that was reported to be 90% in patients who were followed an average of 12 months from initial treatment, according to the most recent publication of our ongoing global patient registry.
•Strong patient compliance, with 80% of patients reporting continued nightly use through five years from initial treatment in our Stimulation Therapy for Apnea Reduction ("STAR") trial.
•Minimally invasive outpatient procedure with short recovery time.
•Long-lasting solution with a battery designed to last approximately 11 years without charging or maintenance.
The results from multiple clinical studies, which include seven sponsored and more than 100 independent clinical studies that evaluated several thousand patients, have shown that our Inspire therapy provides statistically significant and sustained reduction in the severity of patients’ OSA, improvement in sleep-related quality of life and reduction in snoring, as well as high patient compliance rates and a strong safety profile.
Our pivotal STAR trial was designed to demonstrate longitudinal therapy efficacy and included a randomized controlled therapy withdrawal study. The longitudinal study demonstrated an approximately 70% reduction in the median AHI in patients with moderate to severe OSA from a baseline of 29.3 events per hour to 9.0 events per hour at 12 months following initial treatment. STAR trial follow-up has shown results similar to the initial data at 18 months, three years, and five years following initial treatment. At five years, median AHI in patients with moderate to severe OSA remained low at 6.2 events per hour. The effectiveness of Inspire therapy was further demonstrated by the results of the randomized controlled therapy withdrawal study, in which patients in the therapy withdrawal group regressed to near-baseline AHI levels while patients in the control group that continued therapy experienced sustained therapeutic benefits.
In addition to the STAR trial, we have established a global real-world patient registry ("ADHERE") to collect data on safety, effectiveness, weekly usage, overall compliance, and satisfaction from patients who have been implanted with an Inspire system for one year after implant. The target enrollment of 5,000 patients was achieved in 2024 and patient follow-up was completed in 2025 with final results pending analysis. For more details on ADHERE, please see the section titled "Clinical Results and Studies—ADHERE Patient Registry" below.
We sell our Inspire system to hospitals and ambulatory surgery centers ("ASCs") in the U.S. and in select countries in Europe through a direct sales organization, and we sell our Inspire system in Japan and Singapore through distributors. As of December 31, 2025, we had 295 sales territories in the U.S. and 21 outside of the U.S. Our direct sales force engages in sales efforts and promotional activities focused on ENT physicians, and sleep centers. In addition, we highlight our compelling clinical data and value proposition to increase awareness and adoption amongst referring physicians. We build upon this top-down approach with strong direct-to-consumer marketing initiatives to create awareness of the benefits of our Inspire system and drive demand through patient empowerment. This outreach helps to educate thousands of patients on our Inspire therapy.
Our U.S. customers are generally reimbursed for the cost of patient treatment by various third-party payors, such as commercial insurance providers and Medicare. We have secured positive coverage policies with many U.S. commercial payors, including all large national commercial insurers, encompassing over 300 million covered lives in the U.S. We are in active discussions with regional commercial insurers to establish additional positive coverage policies, as well as modify existing positive coverage policies to support reimbursement of Inspire therapy. In parallel, a subset of our market access team, which we refer to as our prior authorization team, is focused on assisting patients and physicians in obtaining prior authorization approvals from commercial payors on a case-by-case basis in advance of treatment with our Inspire therapy. In addition, all seven Medicare
7
Administrative Contractors ("MACs") provide coverage of Inspire therapy when certain medical necessity criteria are met. We also have a U.S. government contract for patients who are treated by the Veterans Health Administration.
Reimbursement in other countries can often be established through a combination of private (commercial insurance) and public funding sources, or at the hospital level through innovation budgets.
Our Competitive Strengths
We believe the continued growth of our company will be driven by the following competitive strengths:
•First to market with an innovative, closed-loop, minimally invasive solution. We have developed the first FDA-approved neurostimulation technology that provides a safe and effective treatment for patients with moderate to severe OSA who have been confirmed to fail or cannot tolerate PAP treatments, such as CPAP. We received a PMA from the FDA in 2014 for our Inspire therapy. Unlike CPAP, which is limited by low patient compliance primarily due to patient discomfort with the mask or device, our innovative, closed-loop, minimally invasive solution is designed to provide comfort and convenience, resulting in high compliance for patients with moderate to severe OSA. We believe we have a significant first mover advantage and momentum over current and future competitors, as physicians have treated more than 125,000 patients with Inspire therapy.
•Significant body of strong clinical data. We have developed a significant body of clinical data that demonstrates the safety and effectiveness, therapy adherence, and long-term sustained benefits of our Inspire therapy. The benefits of treatment with Inspire therapy have been consistent across seven sponsored and more than 100 independent clinical studies that evaluated several thousand patients and have been highlighted in more than 385 peer-reviewed publications. Data reported in these clinical studies also demonstrated a high level of overall patient satisfaction. We believe this favorable data provides us with a significant competitive advantage and will continue to support increased adoption of our Inspire therapy.
•Holistic and targeted approach to market development and patient engagement. We have established a methodical approach to market development which centers on active engagement across three key stakeholders in the OSA treatment paradigm: physicians, sleep centers, and patients. Our sales force is focused on building long-lasting relationships with ENT physicians and sleep centers as we support physicians through all aspects of a case-from diagnosis to surgical support to patient follow-up. In addition, we are highlighting our compelling clinical data set and value proposition to increase awareness and adoption amongst referring physicians. We build upon this top-down approach with a strong direct-to-consumer marketing initiative that further drives demand through patient empowerment. This outreach helps to educate thousands of patients on our Inspire therapy. Our patient call center, the Advisor Care Program, assists patients with making a connection with a qualified healthcare provider based on their specific needs. We are confident that this holistic approach to engagement across multiple constituents will continue to drive increased awareness of and demand for our Inspire therapy.
•Dedicated team focused on providing market access for patients and providers. We have a refined, efficient approach to advance patients, once identified, to placement of the Inspire system. When required, our dedicated prior authorization team helps patients and providers work with commercial payors to secure prior authorization approvals in advance of initial treatment. In addition, by highlighting the compelling clinical data and the value of our Inspire therapy, the market access team proactively works with payors to establish positive coverage policies where needed and update policies to match the FDA criteria where a policy already exists. This highly effective team has been successful in helping providers and patients to secure reimbursement from hundreds of commercial payors to date, and positive coverage policies from most U.S. commercial payors, including all large national payors.
•Strong research and development capabilities and comprehensive intellectual property portfolio. Our commitment to driving innovation has allowed us to achieve continuous, significant improvements of our Inspire therapy. For example, in 2024, we received approval from the FDA for our Inspire V
8
neurostimulator, which we began to market for sale in the U.S. in 2025. We have a comprehensive patent portfolio to protect our intellectual property and technology, with rights as of December 31, 2025 to 119 issued U.S. patents, 83 issued foreign patents, 73 pending U.S. patent applications, and 73 pending foreign patent applications that cover aspects of our Inspire system and future product concepts.
Our Strategy
Our goal is to be a global leader in providing clinically proven innovative solutions that improve sleep, quality of life, and health of patients with moderate to severe OSA. We believe the following strategies will play a critical role in achieving this goal and our future growth:
•Foster strong and consistent patient outcomes. Patient outcomes remain the single most important focus for Inspire as we scale our business, and we have a dedicated patient outcomes team furthering this mission. Our Surgical Implant Trainers are tasked with conducting physician trainings and proctoring implants. Care Pathway Specialists develop and promote consistent post-implant care protocols. Our team of Sleep Support Specialists educate and oversee local sleep lab titrations. We believe these teams are critical to ensuring that outcomes continue to improve even as implant volumes increase around the world.
•Improve the customer experience. We believe that by enhancing interconnectivity, simplifying the care pathway, and closely tracking outcomes, we can optimize the customer experience and improve therapy adherence. We have invested in initiatives that we believe will drive higher quality patient flow to reduce time to treatment and increase the capacity of providers to treat and manage more patients. We expect that this will allow patients and health care providers to more efficiently realize the proven benefits of Inspire therapy. We also continue to invest in our SleepSync™ platform, a cloud-based patient management system which allows patients and physicians alike to remotely monitor key compliance and outcomes measures for connected and coordinated care management, thereby optimizing therapy.
•Promote awareness of and reliance on Inspire therapy among patients, ENT physicians, sleep centers, and referring physicians. We believe that many patients who have failed or cannot tolerate CPAP are unaware of our Inspire therapy as a safe and effective alternative treatment for moderate to severe OSA. We intend to continue to promote awareness of our therapy through training and educating ENT physicians, sleep centers, key opinion leaders, and various medical societies on the proven clinical benefits of Inspire therapy. In addition, we intend to continue to publish additional clinical data in various industry and scientific journals and online, and to present at various industry conferences. We also plan to continue building patient awareness through our direct-to-consumer marketing initiatives, which include paid online search, radio, social media, television, and online videos.
•Utilize our dedicated sales and marketing organization to facilitate further adoption of our Inspire therapy. We plan to continue to utilize our talented sales representatives in existing and new markets to help facilitate further adoption and broaden awareness of our Inspire therapy. Our success to date in developing new markets has been primarily due to our ability to identify new regions with high volume medical centers, educate ENT and sleep physicians, help generate steady patient demand, and provide sufficient support staff to our sales representatives. We believe investing in a scalable, efficient direct sales force and continuing the development of our marketing efforts will help us broaden adoption of our Inspire therapy and drive revenue growth.
•Drive an increase in utilization of Inspire therapy at established centers. In addition to continuing to expand our footprint more broadly, we will also focus on building stronger and deeper relationships with customers. We have extensive learnings through our years of pioneering our hypoglossal nerve stimulation therapy, which we intend to use to educate providers on strategies that allow them to improve their identification and potential treatment of moderate-severe OSA patients.
•Invest in research and development to drive innovation and expand indications. Our foundational commitment to driving innovation and improving patient lives fuels our desire for continuous product development. We intend to invest in existing and next generation technologies to further improve our
9
products and clinical outcomes, optimize patient acceptance and comfort, and broaden the patient population that can benefit from our Inspire therapy. Recent examples of our product innovation include the next generation of the Inspire system and our SleepSync™ programmer. We have a cloud-based patient management system called the SleepSync™ platform which allows physicians to monitor patient compliance and more efficiently coordinate patient care, and the Inspire Sleep app for patients' smartphones. Examples of our efforts to expand our label indications for the Inspire system include obtaining FDA approval in 2023 to offer Inspire therapy to certain pediatric patients with Down syndrome. Additionally in 2023, we received approval from the FDA on an expanded indication which includes an increase on the upper limit of the AHI to 100 events per hour from 65 and raises the body mass index ("BMI") warning in the labeling to 40 from 32.
•Further penetrate and expand into existing and new international markets. We plan to continue to establish and strengthen our presence internationally. Our goal is to further increase sales of our Inspire therapy in existing international markets in Europe, including Germany, France, and the Netherlands, and in the Asia Pacific region, including Japan, Singapore, Hong Kong, and Thailand. We also plan to expand our reach to markets in new regions, such as South Korea. We plan to strategically invest in new markets based on our assessment of market size and opportunity and prospects for compelling reimbursement coding and coverage.
Our Solution for OSA
Overview of Inspire Therapy
Our proprietary Inspire system is the first FDA-approved closed-loop neurostimulation technology that provides a safe and effective treatment for patients with moderate to severe OSA. Both our Inspire IV and Inspire V systems consists of a remote control and the following implantable components (except as otherwise noted):
•in the Inspire IV system, a pressure sensing lead, which detects when the patient is attempting to breathe;
•a neurostimulator, which houses the electronics, battery power for the device, and, as to the Inspire V system, a respiratory sensor; and
•a stimulation lead, which delivers electrical stimulation to the hypoglossal nerve.
A respiratory sensor is used to monitor the patient’s breathing. Our proprietary algorithm tracks breathing patterns and the neurostimulator delivers electrical stimulation at the start of inspiration. This electrical stimulation of the hypoglossal nerve causes a slight forward movement of the back of the tongue that helps maintain an open airway, thereby preventing obstructive events and enabling the patient to inhale freely.
To receive the Inspire system, patients undergo a short outpatient surgical procedure, typically lasting about 30 to 90 minutes, during which the neurostimulator and stimulation lead are implanted, and for the Inspire IV system, a pressure sending lead to monitor the breathing cycle. The Inspire V system incorporates the respiratory sensor inside the neurostimulator so a sensing lead is not required. The procedure is minimally invasive and performed with two small incisions. Patients typically recover quickly and are able to resume normal activities in just a few days. Initial activation of the system occurs 30 days after the implantation. After the initial activation, the patient is instructed to use the therapy each night by turning on their Inspire system before going to sleep using their remote control.
Patients turn their Inspire system on when they plan to go to sleep and turn it off when they awaken. The device has a programmed delay, typically 30 minutes, to allow patients to fall asleep naturally before the device activates. It then monitors the patient’s breathing and delivers mild stimulation to the hypoglossal nerve at the start of the inspiratory phase, causing a slight forward movement at the back of the tongue to maintain an open airway during the inspiratory phase of respiration. The therapy is designed to provide stimulation for each breath to prevent obstructive events.
10
The effectiveness of Inspire therapy to relieve OSA is objectively measured during a sleep study or polysomnogram. A sleep study records a patient’s breathing, airflow, and blood oxygen levels before and after activating the device. Before activation, the patient experiences multiple periods of interrupted breathing, and oxygen levels repeatedly drop before the patient experiences a transient arousal that allows air intake.
Benefits of Inspire Therapy
We believe our Inspire therapy overcomes many of the limitations of PAP and other current treatments of moderate to severe OSA by providing the following key benefits:
•Safe, effective, and durable treatment. Results from our clinical studies provide compelling safety and efficacy data regarding the clinical benefits of Inspire therapy as many as five years after initial treatment. The results from our STAR trial, a five-year follow-up phase III pivotal trial, demonstrated an approximately 70% reduction in the median AHI from a baseline of 29.3 events per hour to 9.0 events per hour at 12 months following initial treatment. STAR trial follow-up has shown similar results to the initial data at 18 months, three years, and five years. At five years, median AHI remained low at 6.2 events per hour. The results from our ADHERE patient registry also reflect similar median AHI reductions to the STAR trial in a real-world setting.
•Closed-loop system. The Inspire system uses proprietary algorithms to continuously monitor a patient’s breathing and provide electrical stimulation during the inspiratory phase, working with the body’s natural actions to keep the airway open during the breathing cycle.
•Comfortable and convenient therapy resulting in high patient satisfaction. Data reported in the most recent publication of our ongoing ADHERE patient registry demonstrated that patients used Inspire therapy an average of 5.7 hours per night an average of 12 months after initial treatment, with overall patient satisfaction reported to be at 90%.
•Strong patient compliance. Results from our STAR trial demonstrated that 80% of patients continue to use Inspire therapy on a nightly basis five years after initial treatment.
•Similar outcomes and usage as CPAP. Several independent clinical studies demonstrating Inspire therapy has similar improvements in symptoms, and similar nightly usage as CPAP.
•Minimally invasive outpatient procedure. The Inspire system’s implantable components are placed during an approximately 30 to 90-minute outpatient procedure. The procedure is minimally invasive and performed with two small incisions. Patients typically recover quickly and are able to resume normal activities within a few days.
•Long-lasting solution. Our Inspire system uses a battery designed to last approximately 11 years without charging or maintenance.
Commercialization of Inspire Therapy
In the U.S., we obtained PMA for our Inspire system in 2014. Additionally, we received a certificate of conformity for commercialization of our Inspire system in the EU in 2010 which allowed us to affix the European Conformity ("CE") mark on our device. Japan's MLHW approved Inspire therapy in 2018 and Inspire therapy was approved in Singapore and Thailand in 2025.
To commercialize our Inspire system, we focus on physician and patient awareness and adoption of our Inspire therapy. To achieve this, our commercialization strategy primarily consists of our direct sales force engaging in sales efforts and promotional activities focused on ENT physicians and sleep centers and highlighting our compelling clinical data and value proposition. Our direct sales force utilizes strong direct-to-consumer marketing initiatives to create awareness of the benefits of our Inspire system. We intend to continue to make significant investments in our direct-to-consumer marketing efforts in existing and new markets throughout the U.S. and Europe.
11
In Singapore, Hong Kong, and Thailand, our commercialization approach is through exclusive distribution partners, who are responsible for local sales and promotional activities focused on ENT physicians, sleep centers, and community awareness. We work closely with the distributors to ensure a globally consistent approach and effective employee and customer training are in place.
In addition, a significant part of our commercialization effort consists of supporting our customers through the reimbursement process. Most commercial U.S. insurers now cover Inspire therapy. For those commercial payors that do not have a positive policy, Inspire provides assistance to patients and physicians on a case-by-case basis to help support appropriate prior authorization approvals in advance of treatment. Medicare also has positive coverage for all states, and we have a U.S. government contract for patients who are treated by the Veterans Health Administration.
Treatment with Inspire Therapy
Patient Selection
Inspire therapy is indicated for patients with moderate to severe OSA (AHI of 15 to 100) who do not have significant central sleep apnea and do not have a complete concentric collapse of the airway at the soft palate level. Patients undergo a drug-induced sleep endoscopy ("DISE") performed by an ENT surgeon in order to confirm that they satisfy this anatomical requirement. In addition, patients in the U.S. and Japan must have been confirmed to fail or be unable to tolerate PAP treatments, such as CPAP, and be 18 years of age or older, though there are no similar requirements for patients in Europe. Patients who fail PAP are those that are not able to eliminate moderate to severe OSA despite PAP usage. Patients who cannot tolerate PAP treatments are those who either are unable to use PAP more than five nights per week for at least four hours per night, or who are unwilling to use PAP treatment.
Implantation
The Inspire system is implanted under general anesthesia through two small incisions. One incision is under the lower jaw, where the stimulation lead is attached around a distal branch of the hypoglossal nerve that is responsible for forward movement of the tongue. A second incision in the upper right chest below the clavicle is used to implant the neurostimulator, which houses all the electronics and battery power for the device, and, for the Inspire IV system, a pressure sensing lead to monitor the breathing cycle. The Inspire V system incorporates the respiratory sensor inside the neurostimulator so a sensing lead is not required. The functionality of the Inspire system is tested in the operating room to verify proper placement of the lead or leads. The Inspire system is powered by an internal battery that is designed to last approximately 11 years without needing to be recharged. After this time, the neurostimulator is replaced during a simple outpatient procedure.
The implantation procedure is performed in an outpatient setting and surgery is completed in approximately 30 to 90 minutes. Patients may experience mild discomfort and swelling at the incision sites for a few days that is usually managed with over-the-counter pain medications. Patients can return home and resume a normal diet shortly after completion of the procedure and resume most daily activities within a few days. The only restriction on their activity is to avoid strenuous activities until the incisions have had time to heal.
Activation
Patients are allowed to heal for a month before the Inspire system is activated through a wireless connection to the device in the clinician’s office. The initial activation is performed by the clinician using the SleepSync™ programmer that is able to turn the system on as well as change various parameters such as the strength, timing, and duration of the stimulation pulse, the stimulating electrode configuration, and the sensitivity of respiration detection. With the exception of pulse strength, the factory default settings are used in the majority of patients. The pulse strength is initially adjusted to the lowest level required to move the tongue forward.
Patients receive a remote control that they use to turn their Inspire system on when they plan to go to sleep and to turn it off when they awaken. The device has a programmed delay, typically 30 minutes, to allow patients to fall asleep naturally before the device activates. It then delivers mild stimulation to the hypoglossal nerve, causing the
12
tongue to move as the patient is inhaling. The remote enables patients to adjust the strength of the stimulation to optimize their therapy and comfort. The range of control given to patients is limited to avoid setting the strength of the stimulation to an ineffective or excessively high level. Patients also have the ability to temporarily pause therapy if they awaken during the night.
Clinical Results and Studies
A significant body of published clinical evidence, which includes seven sponsored and more than 100 independent clinical studies that evaluated several thousand patients, supports the safety and effectiveness of Inspire therapy. The results of the STAR trial, our phase III pivotal clinical trial that served as the basis for the FDA approval of our PMA application, were published in the New England Journal of Medicine, and the results of additional clinical studies have been published in more than 385 peer-reviewed publications.
ADHERE Patient Registry
We have established a global patient registry, which we refer to as our ADHERE patient registry, to collect data on safety, effectiveness, weekly usage, overall compliance, and satisfaction from patients who have been implanted with an Inspire system for one year after Inspire implant. The target enrollment of 5,000 patients was achieved in 2024. The most recent analysis, published in the Journal of Clinical Sleep Medicine in 2022 on 1,963 patients enrolled, showed that patients used Inspire therapy an average of 5.7 hours per night when measured an average of 12 months after implantation. Median AHI was reduced from 33.0 events per hour to 10.2 events per hour and median ESS score improved from 11 to 6 over the same period. Overall satisfaction with Inspire therapy was reported by patients to be 90%, with 92% of patients reporting that they would choose the procedure again. In addition, 91% of patients reported a better experience than CPAP. This same study demonstrated comparable outcomes across five disease severity groups.
Select Recent Clinical Results and Studies
Meta-analysis showed many patients with body mass index greater than 32 kg/m2 benefit from Inspire therapy
Dr. Coleton Evans and colleagues published a meta-analysis and systematic review of studies that reported on adult patients who received Inspire therapy for OSA, and that also included analysis on patients above and below BMI of 32 kg/m2 (a common cutoff for insurance approval). They identified seven studies encompassing 1,572 patients to include in their systematic review, of which four studies (1,017 patients) were included in the meta-analysis. The pooled odds ratio for treatment success for BMI ≥ 32 kg/m2 vs BMI < 32 kg/m2 was 0.87 (95% confidence interval 0.68 - 1.11). This suggests no statistically significant difference in surgical success between the BMI groups, and that many patients with BMI ≥ 32 kg/m2 achieved clinically meaningful objective and subjective improvements with Inspire therapy.
13
Inspire therapy has been shown to effectively treat supine and non-supine obstructive sleep apnea
Dr. Lidice Hernandez and colleagues published a retrospective observational study of 27 patients who had sufficient positional data which showed reductions in both supine and non-supine AHI. The authors concluded that their findings support the clinical utility of Inspire therapy in both positional dependent and non-positional dependent OSA.
Long term follow-up of Inspire therapy in adolescents with Down syndrome
Dr. Danielle Larrow and colleagues published long term follow up data for 33 patients with Down syndrome and OSA. These patients, implanted as adolescents, were part of the 42 patient cohort whose outcomes (published in 2022) supported Inspire’s expanded indications for teenagers with Down syndrome. Follow up time averaged four years with a standard deviation of 1.9 years, at which point 29/33 (88%) demonstrated a 50% reduction in AHI, with an average decrease of 60% across all 33 patients. These data show that adolescents with Down syndrome showed durable improvement in objective measures of their OSA.
Inspire has the potential to improve neurocognitive and psychosocial outcomes
Dr. Arman Saeedi and colleagues published Patient Reported Outcome Measurement Information System ("PROMIS") survey results from a cohort of 42 patients (all aged over 50 years) who had Inspire implanted to treat their OSA. PROMIS surveys are validated and psychometrically sound measures of life domains developed by the U.S. Department of Health and Human Services. This cohort showed a reduction from an average AHI of 31 to an average of 14 while using Inspire therapy for an average of seven hours per night. Their PROMIS scores showed significant post-treatment improvements in sleep impairment, cognitive function, depression, anxiety, anger, and loneliness.
Sales and Marketing
We have established a methodical approach to market development which centers on active engagement across three key stakeholders in the OSA treatment paradigm: patients, physicians, and sleep centers.
We sell our Inspire system through a direct sales force that primarily targets ENT physicians and sleep centers in the U.S., Europe, and Japan, and through distributors in Singapore, Hong Kong, and Thailand. The implant procedure for our Inspire therapy is typically performed by an ENT physician or in some cases by a neurosurgeon. We also focus on sleep centers because they diagnose and manage large volumes of patients with sleep apnea and are often an important referral base for ENT physicians. In addition, because OSA is sometimes diagnosed during other procedures, we have developed programs to help educate general practitioners and specialists in other fields, such as cardiovascular surgeons, electrophysiologists, and dentists, regarding our Inspire therapy.
We continue to make significant investments in our sales and marketing organization by increasing the number of sales support personnel. In 2025, we began optimizing our sales model through targeted territory consolidation and increased field clinical representatives ("FCRs"), consistent with our strategy of a ratio of 1:1 territory manager to FCR. This enables territory managers to focus on therapy awareness, surgeon recruiting and training, and driving the adoption of Inspire therapy, while FCRs provide technical and clinical expertise as well as educational and field support. As of December 31, 2025, we had 295 U.S. sales territories and 275 U.S. FCRs, as compared with 335 U.S. sales territories and 230 U.S. FCRs as of December 31, 2024. Outside of the U.S., we had 21 and 25 sales territories at December 31, 2025 and 2024, respectively.
We seek to recruit sales representatives with strong sales backgrounds, direct experience developing markets with new technologies, and core knowledge of medical device coding, reimbursement, and the prior authorization process. In certain Asian markets, we rely on our distribution partners for local sales and promotional activities.
Direct patient education remains a core growth strategy for us. Our marketing investments focus on efficiently reaching qualified patients across high‑impact channels and the InspireSleep.com website, where they can better understand OSA, learn about Inspire therapy as a proven option for OSA treatment, and get connected with trained providers in their area. Through our tested direct-to-patient messaging, we aim to bring advanced medical
14
topics to an approachable level for patient consumers, We leverage more than a decade of real‑world outcomes and patient stories to demonstrate therapy effectiveness and benefits that can only be achieved by a therapy that has been shown to be used consistently by patients night after night, accelerating patient interest and activation. These efforts continue to support strong awareness, engagement, and conversion.
We continue to refine our communication to health care professionals to reinforce Inspire’s value proposition and support ongoing clinical adoption. The Inspire app remains an important tool for patient education and provider insight through its integration with SleepSync™. Going forward, we expect to further optimize our targeting, strengthen our brand platform across all audiences, and maintain a consistent level of marketing investment.
We operate a call center, known as the Inspire Advisor Care Program, which assists patients in connecting with a qualified healthcare provider based on their specific needs. The program also uses a digital scheduling capability that streamlines and simplifies patient access to care. We plan to continue enhancing and expanding this scheduling capability throughout 2026.
Commercial Activities Outside of the U.S.
Our general practice is to limit commercial investments in countries until such time as there is a determined reimbursement pathway. We have 21 sales territories in Europe and Japan, and we sell our products through distributors in Singapore, Hong Kong, and Thailand. We provide consistent training in geographies outside of the U.S. as is conducted in the U.S. and have established a support team in Europe and Japan for patient outreach and education, implant support, and device programming. In areas in which we use distributors, we assist our distribution partners with patient outreach and education initiatives, as well as with remote implant support and post-implant titration. We expect to continue to scale our commercial activities in Europe as we continue to develop country-wide reimbursement in additional markets. We are currently pursuing regulatory approval in Korea.
Third-Party Reimbursement
Our market access team is responsible for all of our reimbursement processes and initiatives. Our team of professionals are focused on all key aspects of reimbursement, which include prior authorization, coding, coverage, and payment.
Coding and Payment
In the U.S., we sell our products to hospitals and ASCs. These customers in turn bill various third-party payors, such as commercial payors and Medicare, for the cost required to treat each patient. These costs and the related reimbursements for aspects of the Inspire IV and Inspire V therapies can vary and are not the same across commercial payors and government payors. In addition, there are currently, and can be in the future, different codes, modifiers (where applicable), and processes (such as prior authorization) used for our Inspire therapy given the variety of payors. Our customers and providers also have many different models that may result in coding and reimbursement decisions having more or less impact on our revenues and results of operations (for example, fee-for-service and value-based care models).
Third-party payors require physicians and hospitals to identify the service for which they are seeking reimbursement by using Current Procedural Terminology (“CPT") codes, which are created and maintained by the American Medical Association. Physician reimbursement under Medicare is based on a defined fee schedule, the Medicare Physician Fee Schedule, through which payment amounts are determined by the relative values of the professional service rendered. Medicare provides reimbursement to our hospital and ASC customers under the outpatient prospective payment system and ASC prospective payment system, respectively, which provide bundled amounts generally intended to reimburse the hospital or ASC for device and facility costs related to procedures performed in the outpatient setting.
Reimbursement rates from commercial payors vary depending on the procedure performed, the commercial payor, contract terms, and other factors.
15
Commercial Payor and Government Program Coverage
A core pillar of our reimbursement strategy involves broadening our third-party payor coverage when possible. We continue to have active discussions with commercial payors to establish new and modify existing positive coverage policies by highlighting our compelling and robust clinical data, increased patient demand, and support from leading medical societies and key opinion leaders. We have been successful in helping our customers and patients pursue prior authorization approvals from most commercial payors for the Inspire device and procedure. Historically, commercial payors cover approximately 45% to 50% of Inspire implants in the U.S. Medicare Advantage, which is also managed by the private commercial health care plans, covers approximately 15% to 20% of Inspire implants. We estimate that the majority of patients who meet the FDA-approved indication for Inspire therapy are covered by commercial insurance companies and we have secured coverage policies with all major national commercial payors.
In terms of government program coverage, all seven MACs provide coverage of Inspire therapy when certain coverage criteria are met. Fee-for-service Medicare beneficiaries have historically accounted for approximately 25% to 30% of all Inspire system implantations in the U.S. In addition, we have a contract with the U.S. government that covers implantations of our Inspire system performed in Veterans Affairs and military hospitals, which account for approximately 5% to 10% of all Inspire system implantations historically in the U.S.
Prior Authorization Approval Process
A second pillar of our reimbursement strategy includes leveraging our prior authorization team to assist patients and physicians in obtaining appropriate prior authorization approvals from commercial payors in advance of treatment. We believe our prior authorization team is highly effective in working with patients and physicians to support prior authorizations for our Inspire system, including assisting with the appeals process in the event of a denial. Our customers have received thousands of prior authorization approvals from all of the largest commercial payors in the U.S. We believe we will continue to benefit from this efficient prior authorization process.
Reimbursement Outside of the U.S.
Outside the U.S., reimbursement levels vary by country and by region within some countries. Reimbursement is obtained from a variety of sources, including government-sponsored and private health insurance plans, and combinations of both. Some countries require additional clinical data before granting or expanding coverage and reimbursement for our products. In general, obtaining broad-based reimbursement and adequate payment for new technologies is more difficult in these markets than in the U.S. Some countries require new medical technologies to not only be safe and effective, but also to be able to demonstrate clinical benefits that outweigh the costs when compared to the standard of care. As in the U.S., reimbursement decisions can change, resulting in the elimination or reduction of reimbursement payments, which could adversely affect our financial results and our ability to invest in and grow our business.
We currently have country wide reimbursement in Germany, the Netherlands, Switzerland, France, Belgium, the United Kingdom, and Japan. We continue to pursue permanent reimbursement in target markets across the Asia Pacific and Europe, including Spain and the Nordic region.
Research and Development
Product Evolution and Next Generation Products
The first Inspire device was developed by Medtronic Inc. (now Medtronic Public Limited Company), or Medtronic, in the early 1990s as a radio frequency controlled device that required an external apparatus to deliver electrical stimulation to the hypoglossal nerve. The first fully implantable, respiration-sensing, closed-loop Inspire system was developed shortly thereafter. Based on the initial clinical trial results, which were published in 2001, Medtronic began developing what became known as our Inspire II system, introducing a new, more durable stimulation lead and lower-power neurostimulator, and relocating the respiratory sensing lead to between the intercostal muscle layers.
16
After our 2007 inception and contemporaneous spin-off of the Inspire business from Medtronic, our primary focus was to requalify the Inspire II system and resume clinical trial activity. We completed a phase I feasibility trial along with a phase II dosing or patient selection trial in 2009. In 2011, we began our phase III pivotal STAR trial. The STAR trial was completed and published in the New England Journal of Medicine in 2014 and we received PMA in 2014. Additionally, the device was CE marked for commercialization in the EU in 2010.
We continue to invest in advancing our Inspire system with the goal of providing patients more effective and less invasive therapy for OSA. In 2017, we released the Inspire IV neurostimulator, which is 40% smaller than the previous version while maintaining approximately 11 years of battery life. The Inspire IV device was launched in the U.S. in 2017, and in Europe in 2018.
Our latest generation of the Inspire neurostimulator, Inspire V, was approved by the FDA in 2024, and our updated SleepSync™ programmer was approved by the FDA in 2023. Our Bluetooth®-enabled patient remote control was approved by the FDA in 2021. We have launched a cloud-based patient management system called the SleepSync™ platform, which allows physicians to monitor patient compliance and more efficiently coordinate patient care. In 2020, we launched the Inspire Sleep app for patients' smartphones. The app serves as an educational tool and, since 2022, interfaces with the patient remote and SleepSync™ platform, which allows physicians to monitor patient compliance and more efficiently coordinate patient care. We continue to enhance the functionality of this app as part of our overall digital platform development.
The SleepSync™ platform and our app are initial steps in establishing interconnectivity between the patient and their healthcare provider with a long-term plan to improve outcomes by tracking patient activity and adherence, and monitoring for any issues with device use.
Additional Indications
We have sought and continue to seek to expand the approved indications for our Inspire therapy. For instance, in 2023, we received FDA authorization to provide Inspire therapy to the pediatric population with Down syndrome. Also in 2023, the FDA approved an indication expansion to increase the upper limit of AHI to up to 100 events per hour from the original 65 events per hour, and to raise the BMI warning for patients with a BMI of up to 40 from the previous limit of 32.
Our research and development team focuses on our products currently under development, including our clinical studies involving efforts to improve patient selection, expand indications, and simplify patient management, as well as feasibility studies in which we are evaluating new ways to deliver neuromodulation for OSA therapy and different design configurations to enhance product functionality for future generations of the Inspire system. One example is our PREDICTOR study, the objective of which is to determine whether certain patient and/or patient anatomical characteristics, such as pharyngeal width (inside of the mouth), are predictors of the absence of complete concentric collapse at the soft palate, which could help eliminate the need for DISE in some Inspire patients who are less likely to have complete concentric collapse. Enrollment of 600 patients in the study was completed in early 2024. The results of this study suggest that approximately 10% of patients with OSA have complete concentric collapse ("CCC"). In general, the patients with CCC were younger, had a higher BMI, a larger neck circumference, and a higher baseline AHI. Patients with CCC were also more likely to be male as compared to the non-CCC patients. A CART model, combining BMI and neck circumference, was the most accurate prediction of non-CCC, indicating that patients with a BMI of less than 28 or BMI of less than 32 with a neck circumference of less than 17.7 inches were unlikely to have CCC. We believe these results suggest that these patients may not need to undergo DISE screening for CCC.
Competition
Our industry is subject to rapid change from the introduction of new products, technologies, pharmaceuticals, and various activities of industry participants. We are positioned as a second-line therapy in the OSA treatment market for patients with moderate to severe OSA. In the U.S., Inspire therapy is only indicated for patients who have been confirmed to fail or cannot tolerate PAP treatments, such as CPAP.
17
While we are second-line to PAP therapies, there remains some competition with PAP therapies as sleep physicians often remain committed to prescribing PAP despite poor patient adherence to therapy. Our specific PAP-related competitors include ResMed Inc., Philips BV, Fisher & Paykel Healthcare Corporation Limited, and various regional and new-entrant manufacturers. Currently, we have only one direct neurostimulation competitor in the US for the treatment of OSA, Nyxoah SA and its subsidiary Nyxoah, Inc. ("Nyxoah"). Nyxoah provides an open-loop, bilateral stimulation system that does not include a respiratory sensor. Indications for this device differ partially from those for Inspire. In 2025, LivaNova PLC ("LivaNova") also submitted an application to the FDA to market a hypoglossal nerve stimulation device in the U.S. Additionally, we compete with various other second-line therapies to treat OSA, including invasive surgical treatment options such as uvulopalatopharyngoplasty ("UPPP"), maxillomandibular advancement ("MMA"), robotic tongue reduction surgery, and, to a lesser extent, oral appliances, which are primarily used in the treatment of mild to moderate OSA.
Oral appliances and some other surgical treatments are better known to ENT physicians, sleep centers and the other physicians on whom we rely for referrals, but we believe physician awareness of our Inspire therapy is increasing.
Outside of the U.S., in addition to the Inspire therapy, other second-line therapy alternatives that compete with CPAP and PAP include therapies marketed by Nyxoah and LivaNova. Nyxoah markets their open-loop bilateral hypoglossal nerve stimulation device, described above in certain countries, and LivaNova also markets an open-loop neurostimulation device outside the U.S.
Additionally, a drug candidate produced by Apnimed is undergoing a Phase 3 clinical trial to assess the viability of its pharmaceutical to treat OSA. In December 2024, the GLP-1 drug Zepbound (tirzepatide), was FDA approved for treatment of OSA in patients with obesity and moderate to severe OSA. We believe other emerging businesses are in the early stages of developing alternative OSA treatment therapies or early-stage pharmaceutical approaches.
We believe that the primary competitive factors in the OSA treatment market are:
•company, product, and brand recognition;
•product safety, efficacy, reliability, and durability;
•quality and volume of clinical data;
•effective marketing to and education of patients, physicians, and sleep centers;
•product ease of use and patient comfort;
•sales force experience and access;
•product support and service;
•technological innovation, product enhancements, and speed of innovation;
•pricing and revenue strategies;
•procedure costs to patients;
•effectiveness of reimbursement teams and strategies; and
•dedicated practice development and clinical training teams.
We also compete with other medical technology companies to recruit and retain qualified personnel.
18
Intellectual Property
We rely on a combination of patent, copyright, trademark and trade secret laws, and confidentiality and invention assignment agreements to protect our intellectual property rights. As of December 31, 2025, we had rights to 119 issued U.S. patents, which will expire between 2029 and 2043 assuming all required fees are paid, 73 pending U.S. patent applications, 83 issued foreign patents, and 73 pending foreign patent applications. Our patents cover aspects of our current Inspire system and future product concepts. Some of the issued foreign patents and pending foreign patent applications preserve an opportunity to pursue patent rights in multiple countries.
We are currently a party to multiple adversarial proceedings with Nyxoah regarding our patent portfolio. For additional information, see Note 11, Commitments and Contingencies to the consolidated financial statements included elsewhere in this Form 10-K.
As of December 31, 2025, we had 178 pending and registered trademark filings worldwide, some of which may apply to multiple countries.
We also rely, in part, upon unpatented trade secrets, know-how and continuing technological innovation, and may in the future rely upon licensing opportunities, to develop and maintain our competitive position. We protect our proprietary rights through a variety of methods, including confidentiality and assignment agreements with suppliers, employees, consultants, and others who may have access to our proprietary information.
Our pending patent applications may not result in issued patents, and we cannot ensure that any current or subsequently issued patents will adequately protect our products or provide us with any competitive advantage. . See Part I, "Item 1A. Risk Factors — Risks Related to Intellectual Property Matters” for additional information regarding these and other risks related to our intellectual property portfolio and their potential effect on us.
License Agreement with Medtronic
In 2007, we entered into an assignment and license agreement with Medtronic ("the Assignment and License Agreement") pursuant to which Medtronic assigned certain patents and trademarks to us and granted to us a worldwide, royalty-free license to certain other patents and technical information to make, use, import and sell products, and to practice methods in the field of electrical stimulation of the upper airway for the treatment of OSA ("the Field"). We share co-exclusive rights with Medtronic under this license; however, Medtronic may not exercise its rights unless we make an assignment for the benefit of our creditors, file or have filed against us a bankruptcy petition or go into receivership. We also granted to Medtronic certain worldwide, royalty-free, exclusive licenses to the patents Medtronic assigned to us, as well as other intellectual property (including but not limited to Technical Information (as defined in the Assignment and License Agreement)) that applies to a device and methods with certain specifications for use in the Field, to make, use, import and sell products, and to practice methods outside of the Field. The licenses granted are perpetual and irrevocable.
Manufacturing and Supply
We rely on third-party suppliers to manufacture our Inspire system and its components. Outsourcing manufacturing reduces our need for capital investment and reduces operational expense. Additionally, outsourcing provides expertise and capacity necessary to scale up or down based on demand for our Inspire system. We select our suppliers so that our Inspire system and its components are safe and effective, adhere to all applicable regulations, are of the highest quality, and meet our supply needs. We employ a rigorous supplier assessment, qualification, and selection process with the goal of selecting and retaining suppliers that meet the requirements of the FDA and the International Organization for Standardization and quality standards based on our internal policies and procedures. Our quality assurance process seeks to monitor and maintain supplier performance through qualification and periodic supplier reviews and audits.
Certain components used in our Inspire system are supplied by single-source suppliers. Our suppliers manufacture the components they produce for us and test our components and devices to our specifications. We intend to maintain sufficient levels of inventory to enable us to continue our operations while we obtain another
19
supplier in the event that one or more of our single-source suppliers were to encounter a delay in supply or end supply.
We have experienced supply disruptions that began during the COVID-19 pandemic, but to date we have managed to avoid major delays in implant procedures due to those issues. During the third quarter of 2023 and into the first half of 2024, we experienced an inventory supply issue related to our polyurethane-based stimulation leads, one component of the Inspire system currently used only in the European market, as a result of delays in the EU MDR certification process. This issue impacted our revenue in those periods, however, the issue has been resolved. See Part II, Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Overview” for additional information.
Our products are shipped directly to our U.S. customers and to our distributors on a purchase order basis, primarily by a third-party vendor with facilities in California and North Carolina, although we do ship some products from our facility in Minnesota. Warehousing and shipping operations for our European customers are handled by a third-party vendor with a facility located in the Netherlands, and warehousing and shipping operations for our Japanese customers are handled by a third-party with a facility in Japan. Customers do not have the right to return a non-defective product, nor do we place product on consignment. Our sales representatives do not maintain trunk stock.
Government Regulation
As a global technology company, we are subject to significant government regulation, compliance requirements, fees and costs, both in the U.S. and abroad. These regulatory requirements subject our products and our business to numerous risks that are specifically discussed within Part I, Item 1A, “Risk Factors” within this Annual Report on Form 10-K.
Our products and our operations are subject to extensive regulation by the FDA and other federal and state authorities in the U.S., as well as comparable authorities in the European Economic Area ("EEA"), Japan, and in Thailand, South Korea and Australia (where our products are approved for sale but where we have not yet commercialized them). In the U.S., our products are subject to regulation as medical devices under the Federal Food, Drug, and Cosmetic Act ("FDCA") as implemented and enforced by the FDA. The FDA regulates the development, design, non-clinical and clinical research, manufacturing, safety, efficacy, labeling, packaging, storage, installation, servicing, recordkeeping, premarket clearance or approval, import, export, adverse event reporting, advertising, promotion, marketing and distribution, and import and export of medical devices to help ensure that medical devices distributed domestically are safe and effective for their intended uses and otherwise meet the requirements of the FDCA.
In addition to U.S. regulations, we are subject to a variety of regulations in the EEA governing clinical studies and the commercial sales and distribution of our products. Whether or not we have or are required to obtain FDA clearance or approval for a product, we will be required to obtain authorization before commencing clinical studies and to obtain marketing authorization, approval or certification of our products under the comparable regulatory authorities of countries outside of the U.S. or notified bodies before we can commercialize our products in those countries. The approval/certification process varies from country to country and the time may be longer or shorter than that required for FDA clearance or approval.
We expect additional state, federal, and foreign healthcare reform measures to be adopted in the future, which may adversely affect our business. For additional information, see Part I, Item 1A, “Risk Factors - Current and future healthcare reform legislation or regulation may increase the difficulty and cost for us to commercialize our products and could harm our business, financial condition and results of operations.”
FDA Premarket Clearance and Approval Requirements
Unless an exemption applies, each medical device commercially distributed in the U.S. requires either FDA clearance of a 510(k) premarket notification or PMA. Under the FDCA, medical devices are classified into one of three classes-Class I, Class II, or Class III-depending on the degree of risk associated with each medical device and the extent of manufacturer and regulatory control needed to ensure its safety and effectiveness. Class I
20
includes devices with the lowest risk to the patient and are those for which safety and effectiveness can be assured by adherence to the FDA’s General Controls for medical devices, which include compliance with the applicable portions of the FDA's Quality Management System Regulation ("QMSR"), facility registration and product listing, reporting of adverse medical events, and truthful and non-misleading labeling, advertising, and promotional materials. Class II devices are subject to the FDA’s General Controls, and special controls as deemed necessary by the FDA to ensure the safety and effectiveness of the device. While most Class I devices are exempt from the 510(k) premarket notification requirement, manufacturers of most Class II devices are required to submit to the FDA a premarket notification under Section 510(k) of the FDCA requesting permission to commercially distribute the device. The FDA’s permission to commercially distribute a device subject to a 510(k) premarket notification is generally known as 510(k) clearance. Under the 510(k) process, the manufacturer must submit to the FDA a premarket notification demonstrating that the device is “substantially equivalent” to either a device that was legally marketed prior to May 28, 1976, the date upon which the Medical Device Amendments of 1976 were enacted, or another legally marketed device that was cleared through the 510(k) process.
Devices deemed by the FDA to pose the greatest risks, such as life-sustaining, life-supporting or some implantable devices, or devices that have a new intended use, or use advanced technology that is not substantially equivalent to that of a legally marketed device, are placed in Class III, requiring approval of a PMA. Some pre-amendment devices are unclassified but are subject to the FDA’s premarket notification and clearance process in order to be commercially distributed.
Our currently marketed Inspire products are Class III devices which have received PMA.
PMA Pathway
In a PMA, the manufacturer must demonstrate that the device is safe and effective, and the PMA must be supported by extensive data, including data from preclinical studies and human clinical studies. The PMA must also contain a full description of the device and its components, a full description of the methods, facilities and controls used for manufacturing, and proposed labeling. If the FDA accepts a submitted PMA application for substantive review, it has 180 days under the FDCA to complete its review, although in practice, the FDA’s review often takes significantly longer. In addition, the FDA will generally conduct a preapproval inspection of the applicant or its third-party manufacturers’ or suppliers’ manufacturing facility or facilities to ensure compliance with the QMSR.
The FDA will approve the device for commercial distribution if it determines that the data and information in the PMA constitute valid scientific evidence and that there is reasonable assurance that the device is safe and effective for its intended use(s). The FDA may approve a PMA with post-approval conditions intended to ensure the safety and effectiveness of the device, including, among other things, restrictions on labeling, promotion, sale and distribution, and collection of long-term follow-up data from patients in the clinical study that supported PMA or requirements to conduct additional clinical studies post-approval. The FDA may condition PMA on some form of post-market surveillance when deemed necessary to protect public health or to provide additional safety and efficacy data for the device in a larger population or for a longer period of use. In such cases, the manufacturer might be required to follow certain patient groups for a number of years and to make periodic reports to the FDA on the clinical status of those patients. Failure to comply with the conditions of approval can result in material adverse enforcement action, including withdrawal of the approval.
Certain changes to an approved device, such as changes in manufacturing facilities, methods, or quality control procedures, or changes in the design performance specifications, which affect the safety or effectiveness of the device, require submission of a PMA supplement. PMA supplements often require submission of the same type of information as a PMA, except that the supplement is limited to information needed to support any changes from the device covered by the original PMA and may not require as extensive clinical data or the convening of an advisory panel. Certain other changes to an approved device require the submission of a new PMA, such as when the design change causes a different intended use, mode of operation, and technical basis of operation, or when the design change is so significant that a new generation of the device will be developed, and the data that were submitted with the original PMA are not applicable for the change in demonstrating a reasonable assurance of safety and effectiveness.
21
Clinical Studies
Clinical studies are almost always required to support a PMA submission and may be required to support certain PMA supplements. All clinical investigations of investigational devices to determine safety and effectiveness must be conducted in accordance with the FDA’s investigational device exemption ("IDE") regulations which govern investigational device labeling, prohibit promotion of the investigational device, and specify an array of recordkeeping, reporting and monitoring responsibilities of study sponsors and study investigators. If the device presents a “significant risk” to human health, as defined by the FDA, the FDA requires the device sponsor to submit an IDE application to the FDA, which must become effective prior to commencing human clinical studies. A significant risk device is one that presents a potential for serious risk to the health, safety or welfare of a patient and either is implanted, used in supporting or sustaining human life, substantially important in diagnosing, curing, mitigating or treating disease or otherwise preventing impairment of human health, or otherwise presents a potential for serious risk to a subject. The IDE will automatically become effective 30 days after receipt by the FDA unless the FDA notifies the company that the investigation may not begin. An IDE supplement must also be submitted to, and approved by, the FDA before a sponsor or investigator may make a change to the investigational plan that may affect its scientific soundness, study plan or the rights, safety or welfare of human subjects.
If an IDE application is approved by the FDA and one or more institutional review boards ("IRBs"), human clinical studies may begin at a specific number of investigational sites with a specific number of patients, as approved by the FDA. If the device presents a non-significant risk to the patient, a sponsor may begin the clinical study after obtaining approval for the study by one or more IRBs without separate approval from the FDA, but must still follow abbreviated IDE requirements, such as monitoring the investigation, ensuring that the investigators obtain informed consent, and labeling and record-keeping requirements.
During a study, the sponsor is required to comply with the applicable FDA requirements, including, for example, study monitoring, selecting clinical investigators and providing them with the investigational plan, ensuring IRB review, adverse event reporting, record keeping, and prohibitions on the promotion of investigational devices or on making safety or effectiveness claims for them. Additionally, after a study begins, the sponsor, the FDA or the IRB could suspend or terminate a clinical study at any time for various reasons, including a belief that the risks to study subjects outweigh the anticipated benefits.
Expedited Development and Review Programs
Following passage of the 21st Century Cures Act, the FDA implemented the Breakthrough Devices Program, which is a voluntary program offered to manufacturers of certain medical devices and device-led combination products, including ours, that may provide for more effective treatment or diagnosis of life-threatening or irreversibly debilitating diseases or conditions. The goal of the program is to provide patients and health care providers with more timely access to qualifying devices by expediting their development, assessment and review, while preserving the statutory standards for FDA marketing authorization. The program is available to medical devices that meet certain eligibility criteria, including that the device provides more effective treatment or diagnosis of life-threatening or irreversibly debilitating diseases or conditions, and that the device meets one of the following criteria: (i) the device represents a breakthrough technology, (ii) no approved or cleared alternatives exist, (iii) the device offers significant advantages over existing approved or cleared alternatives, or (iv) the availability of the device is in the best interest of patients. Breakthrough Device designation provides certain benefits to device developers, including more interactive and timely communications with FDA staff, use of post-market data collection, when scientifically appropriate, to facilitate expedited and efficient development and review of the device, opportunities for efficient and flexible clinical study design, and prioritized review of premarket submissions.
Post-market Regulation
After a device is cleared or approved for marketing, numerous and pervasive regulatory requirements continue to apply. These include:
•establishment registration and device listing with the FDA;
22
•QMSR requirements, which require manufacturers, including third-party manufacturers, to follow stringent design, testing, control, documentation, and other quality assurance procedures during all aspects of the design and manufacturing process;
•labeling and marketing regulations, which require that promotion is truthful, not misleading, fairly balanced, provide adequate directions for use, and that all claims are substantiated, and also prohibit the promotion of products for unapproved or “off-label” uses and impose other restrictions on labeling; FDA guidance on off-label dissemination of information and responding to unsolicited requests for information;
•clearance or approval of product modifications to 510(k)-cleared devices that could significantly affect safety or effectiveness or that would constitute a major change in intended use of one of our cleared devices, or approval of a supplement for certain modifications to PMA devices;
•medical device reporting regulations, which require that a manufacturer report to the FDA if a device it markets may have caused or contributed to a death or serious injury, or has malfunctioned and the device or a similar device that it markets would be likely to cause or contribute to a death or serious injury, if the malfunction were to recur;
•correction, removal, and recall reporting regulations, which require that manufacturers report to the FDA field corrections and product recalls or removals if undertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA that may present a risk to health;
•complying with the laws and regulations requiring Unique Device Identifiers (UDI) on devices and also requiring the submission of certain information about each device to the FDA’s Global Unique Device Identification Database (GUDID);
•the FDA’s recall authority, whereby the agency can order device manufacturers to recall from the market a product that is in violation of governing laws and regulations; and
•post-market surveillance activities and regulations, which apply when deemed by the FDA to be necessary to protect public health or to provide additional safety and effectiveness data for the device.
Our manufacturing processes are required to comply with the applicable portions of the QMSR, which currently cover the methods and the facilities, controls for the design, manufacture, testing, production, processes, controls, quality assurance, labeling, packaging, distribution, installation, and servicing of finished devices intended for human use. The QMSR also requires, among other things, maintenance of a medical device master file and complaint files. As a manufacturer, our facilities, records, and manufacturing processes are subject to periodic scheduled or unscheduled inspections by the FDA. Our failure to maintain compliance with the QMSR or other applicable regulatory requirements could result in the shut-down of, or restrictions on, our manufacturing operations and the recall or seizure of our products. The discovery of previously unknown problems with any of our products, including unanticipated adverse events or adverse events of increasing severity or frequency, whether resulting from the use of the device within the scope of its clearance or off-label by a physician in the practice of medicine, could result in restrictions on the device, including the removal of the product from the market or voluntary or mandatory device recalls.
The FDA has broad regulatory compliance and enforcement powers. If the FDA determines that we failed to comply with applicable regulatory requirements, it can take a variety of compliance or enforcement actions, which may result in any of the following sanctions:
•warning letters, untitled letters, fines, injunctions, consent decrees, and civil penalties;
•recalls, withdrawals, or administrative detention or seizure of our products;
•operating restrictions or partial suspension or total shutdown of production;
23
•refusing or delaying requests for 510(k) marketing clearance or PMAs of new products or modified products;
•withdrawing 510(k) clearances or PMAs that have already been granted;
•refusal to grant export or import approvals for our products; or
•criminal prosecution.
Foreign Regulation
In order for us to market our products in countries outside the U.S., we must obtain regulatory approvals or certifications and comply with extensive product and quality system regulations in other countries. These regulations, including the requirements for approvals, clearance or certifications and the time required for regulatory review, vary from country to country. Some countries have regulatory review processes that are substantially longer than U.S. processes. Failure to obtain regulatory approval or certification in a timely manner and meet all of the local requirements including language and specific safety standards in any foreign country in which we plan to market our products could prevent us from marketing products in such countries or subject us to sanctions and fines.
Regulation of Medical Devices in the European Union
The EU has adopted specific directives and regulations regulating the design, manufacture, clinical investigation, conformity assessment, labeling and adverse event reporting for medical devices.
Until May 25, 2021, medical devices were regulated by Council Directive 93/42/EEC (the “EU Medical Devices Directive”), and Directive 90/385/EEC (“AIMDD”) which have been repealed and replaced by the EU Medical Devices Regulation. The validity of our certificates, initially granted under the AIMDD, has been extended by virtue of the amendment to the EU Medical Devices Regulation, specifically Regulation (EU) 2023/607 as regards the transitional provisions for certain medical devices. Surveillance of the initial AIMDD certificate has been transferred from our original notified body BSI, to our current notified body DEKRA. This makes it possible for us to sell off inventory that is CE marked and labeled under the AIMDD. The Inspire system is also now CE marked under the EU Medical Devices Regulation. Unlike the EU Medical Devices Directive and Active Implantable Medical Device Directive, the EU Medical Devices Regulation is directly applicable in EU member states without the need for member states to implement into national law.
In the EU, there is currently no premarket government review of medical devices. However, all medical devices placed on the EU market must meet general safety and performance requirements, including the requirement that a medical device must be designed and manufactured in such a way that, during normal conditions of use, it is suitable for its intended purpose. Medical devices must be safe and effective and must not compromise the clinical condition or safety of patients, or the safety and health of users and – where applicable – other persons, provided that any risks which may be associated with their use constitute acceptable risks when weighed against the benefits to the patient and are compatible with a high level of protection of health and safety, taking into account the generally acknowledged state of the art.
Compliance with the general safety and performance requirements is a prerequisite for European conformity marking (“CE mark”) without which medical devices cannot be marketed or sold in the EU. To demonstrate compliance with the general safety and performance requirements medical device manufacturers must undergo a conformity assessment procedure, which varies according to the type of medical device and its (risk) classification. Except for low-risk medical devices (Class I), where the manufacturer can self-assess the conformity of its products with the general safety and performance requirements (except for any parts which relate to sterility, metrology or reuse aspects), a conformity assessment procedure requires the intervention of a notified body. Notified bodies are independent organizations designated by EU member states to assess the conformity of devices before being placed on the market. A notified body would typically audit and examine a product’s technical dossiers and the manufacturer’s quality system. If satisfied that the relevant product conforms to the relevant general safety and performance requirements, the notified body issues a certificate of conformity, which
24
the manufacturer uses as a basis for its own declaration of conformity. The manufacturer may then apply the CE mark to the device, which allows the device to be placed on the market throughout the EU.
Throughout the term of the certificate of conformity, the manufacturer will be subject to periodic surveillance audits to verify continued compliance with the applicable requirements. In particular, there will be a new audit by the notified body before it will renew the relevant certificate(s).
The EU Medical Devices Regulation requires that before placing a device, other than a custom-made device, on the market, manufacturers (as well as other economic operators such as authorized representatives and importers) must register by submitting identification information to the electronic system (Eudamed), unless they have already registered. The information to be submitted by manufacturers (and authorized representatives) also includes the name, address and contact details of the person or persons responsible for regulatory compliance. The new Regulation also requires that before placing a device, other than a custom-made device, on the market, manufacturers must assign a unique identifier to the device and provide it along with other core data to the unique device identifier (“UDI”) database. These new requirements aim at ensuring better identification and traceability of the devices. Each device – and as applicable, each package – will have a UDI composed of two parts: a device identifier (“UDI-DI”) specific to a device, and a production identifier (“UDI-PI”) to identify the unit producing the device. Manufacturers are also notably responsible for entering the necessary data on Eudamed, which includes the UDI database, and for keeping it up to date. The obligations for registration in EUDAMED will become applicable on May 28, 2026 (for the first four modules related to (i) economic operators, (ii) UDI/devices registrations, (iii) NB/Certificates, and (iv) market surveillance). Until the effective date, respectively until Eudamed is fully functional with regard to other modules, the corresponding provisions of the EU Medical Devices Directive and the AIMDD, respectively national provisions, continue to apply for the purpose of meeting the obligations laid down in the provisions regarding exchange of information, including, and in particular, information regarding registration of devices and economic operators.
All manufacturers placing medical devices into the market in the EU must comply with the EU medical device vigilance system. Under this system, serious incidents and Field Safety Corrective Actions (“FSCAs”) must be reported to the relevant authorities of the EU member states. Manufacturers are required to take FSCAs defined as any corrective action for technical or medical reasons to prevent or reduce a risk of a serious incident associated with the use of a medical device that is made available on the market. An FSCA may include the recall, modification, exchange, destruction or retrofitting of the device.
The aforementioned EU rules are generally applicable in the EEA which consists of the 27 EU member states plus Norway, Liechtenstein, and Iceland.
Brexit and the UK Regulatory Framework
Since January 1, 2021, the Medicines and Healthcare Products Regulatory Agency (“MHRA”) has become the sovereign regulatory authority responsible for Great Britain (i.e. England, Wales and Scotland) medical device market according to the requirements provided in the Medical Devices Regulations 2002 (SI 2002 No 618, as amended)("UK Medical Devices Regulations") that sought to give effect to EU Medical Devices Directive and AIMDD whereas Northern Ireland broadly continues to be governed by EU rules according to the Northern Ireland Protocol. Following the end of the United Kingdom's ("UK" withdrawal from the EU ("Brexit") transitional period on January 1, 2021, all medical devices are required to be registered with the MHRA before being placed on the Great Britain market. The MHRA only registers devices where the manufacturer or their UK responsible person has a registered place of business in the UK. Since January 1, 2022, manufacturers based outside the UK need to appoint a UK responsible person that has a registered place of business in the UK to register devices with the MHRA.
On June 16, 2025, an amendment to the UK Medical Devices Regulations came into force intended to clarify and strengthen the post-market surveillance requirements for medical devices in Great Britain. This amendment aims to facilitate greater traceability of incidents and trends enabling the MHRA to act swiftly when needed to address safety issues and support the entire health system in better protecting patients. Under the UK Medical Devices Regulations, in order to be lawfully placed on the Great Britain market, class I (non-sterile, non-measuring or non-re-useable) medical devices need to be “UKCA” self-certified, and other medical devices need to be “UKCA”
25
certified by a UK approved body. However, certain medical devices in compliance with: (1) the EU Medical Devices Directive can continue to be placed on the Great Britain market until the sooner of certificate expiration or June 30, 2028; or (2) the EU Medical Devices Regulation can continue to be placed on the Great Britain market until June 30, 2030. The MHRA has confirmed that it intends to launch a consultation regarding the indefinite recognition of such medical devices in Great Britain which is expected this year.
In addition, the trade deal between the UK and the EU generally provides for cooperation and exchange of information between the parties in the areas of product safety and compliance, including market surveillance, enforcement activities and measures, standardization-related activities, exchanges of officials, and coordinated product recalls. As such, processes for compliance and reporting should reflect requirements from regulatory authorities.
Under the terms of the Northern Ireland Protocol, Northern Ireland follows EU rules on medical devices and devices marketed in Northern Ireland require assessment according to the EU regulatory regime. Such assessment may be conducted by an EU notified body, in which case a CE mark is required before placing the device on the market in the EU or Northern Ireland. Alternatively, if a UK notified body conducts such assessment, a “UKNI” mark and a CE mark are applied, and the device may only be placed on the market in Northern Ireland and not the EU.
Similarly, we are subject to regulations and product registration requirements in many foreign countries in which we may sell our products, including in the areas of:
•design, development, manufacturing, and testing;
•product standards;
•product safety;
•product safety reporting;
•marketing, sales, and distribution;
•packaging and storage requirements;
•labeling requirements;
•content and language of instructions for use;
•clinical studies;
•record keeping procedures;
•advertising and promotion;
•recalls and field corrective actions;
•post-market surveillance, including reporting of deaths or serious injuries and malfunctions that, if they were to recur, could lead to death or serious injury;
•import and export restrictions;
•tariff regulations, duties, and tax requirements;
•registration for reimbursement; and
•necessity of testing performed in country by distributors for licensees.
26
The time required to obtain clearance or certification required by foreign countries may be longer or shorter than that required for FDA clearance, and requirements for licensing a product in a foreign country may differ significantly from FDA requirements.
Federal, State, and Foreign Fraud and Abuse Laws
In addition to FDA restrictions on marketing and promotion of drugs and devices, other federal, state, and foreign laws restrict our business practices. These laws include, without limitation, foreign, federal, and state anti-kickback and false claims laws, as well as transparency laws regarding payments or other items of value provided to healthcare providers.
The federal Anti-Kickback Statute prohibits, among other things, knowingly and willfully offering, paying, soliciting or receiving any remuneration (including any kickback, bribe or rebate), directly or indirectly, overtly or covertly, in cash or in kind to induce or in return for purchasing, leasing, ordering or arranging for or recommending the purchase, lease or order of any good, facility, item or service reimbursable, in whole or in part, under Medicare, Medicaid or other federal healthcare programs. The term “remuneration” has been broadly interpreted to include anything of value, including stock, stock options, and the compensation derived through ownership interests.
Although there are a number of statutory exceptions and regulatory safe harbors protecting some common activities from prosecution, the exceptions and safe harbors are drawn narrowly. Failure to meet all of the requirements of a particular applicable statutory exception or regulatory safe harbor does not make the conduct per se illegal under the federal Anti-Kickback Statute. Instead, the legality of the arrangement will be evaluated on a case-by-case basis based on a cumulative review of all its facts and circumstances. Conduct and business arrangements that do not fully satisfy one of these safe harbor provisions may result in increased scrutiny by government enforcement authorities. Several courts have interpreted the statute’s intent requirement to mean that if any one purpose of an arrangement involving remuneration is to induce referrals of federal healthcare covered business, the federal Anti-Kickback Statute has been violated. In addition, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation.
The majority of states also have anti-kickback laws which establish similar prohibitions and in some cases may apply more broadly to items or services covered by any third-party payor, including commercial insurers and self-pay patients.
The federal civil False Claims Act prohibits, among other things, any person or entity from knowingly presenting, or causing to be presented, a false or fraudulent claim for payment or approval to the federal government or knowingly making, using or causing to be made or used a false record or statement material to a false or fraudulent claim to the federal government. A claim includes “any request or demand” for money or property presented to the U.S. government. The federal civil False Claims Act also applies to false submissions that cause the government to be paid less than the amount to which it is entitled, such as a rebate. Intent to deceive is not required to establish liability under the civil federal civil False Claims Act. Moreover, a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the federal civil False Claims Act. In addition, private parties may initiate “qui tam” whistleblower lawsuits against any person or entity under the federal civil False Claims Act in the name of the government and share in the proceeds of the lawsuit. The government may further prosecute conduct constituting a false claim under the federal criminal False Claims Act. The criminal False Claims Act prohibits the making or presenting of a claim to the government knowing such claim to be false, fictitious or fraudulent and, unlike the federal civil False Claims Act, requires proof of intent to submit a false claim.
The Civil Monetary Penalty Law imposes penalties against any person or entity that, among other things, is determined to have presented or caused to be presented a claim to a federal healthcare program that the person knows or should know is for an item or service that was not provided as claimed or is false or fraudulent, or offering or transferring remuneration to a federal healthcare beneficiary that a person knows or should know is likely to influence the beneficiary’s decision to order or receive items or services reimbursable by the government from a particular provider or supplier.
27
The Health Insurance Portability and Accountability Act of 1996 ("HIPAA") also created additional federal criminal statutes that prohibit among other actions, knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program, including private third-party payors, knowingly and willfully embezzling or stealing from a healthcare benefit program, willfully obstructing a criminal investigation of a healthcare offense, and knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services. Similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation.
More generally, expansion in the government’s role in the U.S. healthcare industry has led to (and may in the future lead to) additional regulation and oversight that impacts us. A recent example is the Wasteful and Inappropriate Service Reduction Model (“WISeR”) by CMS which tests the use of enhanced technology such as AI and machine learning to assess coverage determinations for a select set of items and services, including implantation of electric nerve stimulators, that CMS has determined (1) may pose concerns related to patient safety if delivered inappropriately, (2) have existing publicly available coverage criteria, or (3) may involve prior reports of fraud, waste, and abuse. WISeR will run for six performance years from January 1, 2026 to December 31, 2031 in six states: New Jersey, Ohio, Oklahoma, Texas, Arizona and Washington. So far, the impact on our overall sales volumes from WISeR cannot be quantified, but it has caused some confusion among customers in the six states that are part of the program.
Many foreign countries have similar laws relating to healthcare fraud and abuse. Foreign laws and regulations may vary greatly from country to country. For example, the advertising and promotion of medical devices are subject to some general principles set forth in EU legislation. According to the EU Medical Devices Regulation, only devices that are CE marked may be marketed and advertised in the EU in accordance with their intended purpose. Directive 2006/114/EC concerning misleading and comparative advertising and Directive 2005/29/EC on unfair commercial practices, while not specific to the advertising of medical devices, also apply to the advertising thereof and contain general rules, for example, requiring that advertisements are evidenced, balanced and not misleading. Specific requirements are defined at a national level. EU member states’ laws related to the advertising and promotion of medical devices, which vary between jurisdictions, may limit or restrict the advertising and promotion of products to the general public and may impose limitations on promotional activities with healthcare professionals. These laws, which vary between jurisdictions (thus making compliance more complex), may limit or restrict the advertising and promotion of our products to the general public and may impose limitations on our promotional activities with healthcare professionals. Many EU member states have adopted specific anti-gift statutes that further limit commercial practices for our products, in particular vis-à-vis healthcare professionals and organizations.
Additionally, there has been a recent trend of increased foreign, federal, and state regulation of payments and transfers of value provided to healthcare professionals or entities. In the U.S., the federal Physician Payments Sunshine Act imposes annual reporting requirements on certain drug, biologics, medical supplies and device manufacturers for which payment is available under Medicare, Medicaid or CHIP for payments and other transfers of value provided by them, directly or indirectly, to physicians, as defined by statute, certain other non-physician practitioners such as physician assistants and nurse practitioners, and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family members. Also, many U.S. states have similar fraud and abuse statutes or regulations that may be broader in scope and may apply regardless of payor, in addition to items and services reimbursed under Medicaid and other state programs. In the EU, there has also been a recent trend of increased regulation of payments and transfers of value provided to healthcare professionals or entities and many EU member states have adopted national "Sunshine Acts" which impose reporting and transparency requirements (often on an annual basis), similar to the requirements in the United States, on medical device manufacturers. Certain foreign countries and U.S. states also mandate implementation of commercial compliance programs, impose restrictions on device manufacturer marketing practices and require tracking and reporting of gifts, compensation, and other remuneration to healthcare professionals and entities.
Violation of any of the federal and state healthcare laws described above or any other governmental regulations that apply to device manufacturers may result in significant penalties, including the imposition of significant civil, criminal and administrative penalties, damages, disgorgement, monetary fines, imprisonment, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, contractual damages,
28
reputational harm, diminished profits and future earnings, additional reporting requirements and/or oversight if the entity becomes subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, and curtailment of operations. In addition, responding to investigations of alleged violations of healthcare laws can be time-and resource-consuming and can divert management’s attention from the business. Any such investigation or settlement could increase our costs or otherwise have an adverse effect on our business. Even an unsuccessful challenge or investigation into our practices could cause adverse publicity and be costly to respond to.
Data Privacy and Security Laws
Numerous state, federal and foreign laws, regulations, and standards govern the collection, use, access to, confidentiality and security of health-related and other personal information, and could apply now or in the future to our operations or the operations of our partners. In the United States, numerous federal and state laws and regulations, including data breach notification laws, health information privacy and security laws, including HIPAA, and consumer protection laws and regulations govern the collection, use, disclosure, and protection of health-related and other personal information. In addition, certain foreign laws govern the privacy and security of personal data, including health-related data. For example, the General Data Protection Regulation imposes strict requirements for processing the personal data of individuals within the EEA. Privacy and security laws, regulations, and other obligations are constantly evolving, may conflict with each other to complicate compliance efforts, and can result in investigations, proceedings, or actions that lead to significant civil and/or criminal penalties and restrictions on data processing.
Anti-Bribery and Corruption Laws
Our U.S. operations are subject to the FCPA. We are required to comply with the FCPA, which generally prohibits covered entities and their intermediaries from engaging in bribery or making other prohibited payments to foreign officials for the purpose of obtaining or retaining business or other benefits. In addition, the FCPA imposes accounting standards and requirements on publicly traded U.S. corporations and their foreign affiliates, which are intended to prevent the diversion of corporate funds to the payment of bribes and other improper payments, and to prevent the establishment of “off books” slush funds from which such improper payments can be made. We also are subject to similar anticorruption legislation implemented in Europe through EU member state laws and under the Organization for Economic Co-operation and Development’s Convention on Combating Bribery of Foreign Public Officials in International Business Transactions.
Seasonality
Historically, we have experienced seasonality in our first and fourth fiscal quarters, and we expect this trend to continue. In the U.S., we have experienced, and may in the future experience, higher sales in the fourth quarter as a result of patients having paid their annual insurance deductibles in full, thereby reducing their out-of-pocket costs. Conversely, in the first quarter, many U.S. patients' insurance deductibles reset, requiring more out-of-pocket costs, which negatively impacts our sales during this period. We have also begun to experience some seasonality during summer months in the U.S. and Europe, which we believe is attributable to the postponement of elective surgeries due to summer vacation plans of physicians and patients.
Human Capital
We take pride in our innovative and collaborative work environment, which we believe has been key to our success. We strive to maintain this environment by fostering an inclusive workforce, offering competitive compensation and benefits, promoting open communication, prioritizing employee health, wellbeing and engagement, and providing robust training and development programs.
Employees
As of December 31, 2025, we had 1,333 employees, of which 1,243 are in the U.S., 83 are in Europe and 7 are in Japan. We increased the number of employees by 7% during 2025 to support the growth of our business. As of
29
December 31, 2025, 52% of our U.S. workforce identified as female, and 15% identified as a member of minority racial group.
None of our employees are currently subject to a collective bargaining agreement or represented by a trade or labor union. We consider our relationship with our employees to be good.
Code of Business Conduct and Ethics
Inspire is committed to conducting business in accordance with high ethical standards and applicable laws. We maintain, and all of our employees are expected to adhere to, our Code of Business Conduct and Ethics (the “Code of Conduct”), which serves as the foundation of our company’s culture. All employees and individual contractors are expected to certify annually that they understand and will comply with the expectations contained in the Code of Conduct. We maintain an anonymous hotline for employees to report concerns regarding violations of the Code of Conduct and a whistleblower policy addressing our policies and processes to protect the confidential anonymous reporting of concerns regarding accounting or auditing matters.
Compensation and Benefits
We strive to pay competitive salaries and maintain a comprehensive benefits package that helps our employees and their families maintain health and well-being—both physically and financially. Our human capital strategies, initiatives, and outcomes are reviewed on a regular basis with our Board’s Organization and Compensation Committee to ensure alignment with the company’s overall business strategies. The Committee engages an independent consulting firm to assess the market competitiveness of our compensation programs and offerings.
Inspire most recently completed a pay equity analysis in 2025. We expect to continue to review pay equity on a regular basis.
We believe strongly in providing employees with the opportunity to participate as owners of the company. Many of our full-time employees are eligible to receive stock awards, which may include stock options, restricted stock units, or performance stock units. All U.S. employees are also eligible to elect to participate in our employee stock purchase program.
Our standard employee benefits package is available to all full-time employees (except for variations required by state or country-specific laws). Standard U.S. employee benefits available to all full-time employees include medical, dental, and vision insurance, identity protection, disability insurance, life and AD&D insurance, 401(k) employer match, and paid holidays. Additionally, we recognize that Inspire employees have diverse needs for time off from work and maintain a flexible time off (“FTO”) policy, which provides all full-time employees the opportunity to take time off as needed without the need to accrue a specific amount of paid time off each year. Our FTO policy allows employees to take time off for any reason, including vacation, personal time, volunteering, school commitments, and religious holidays not observed by our paid holiday calendar.
Talent Acquisition
To facilitate our continued evolution and growth, it is imperative that we hire exceptional talent and invest in the growth and development of our existing employees. We develop and set an annual hiring plan to understand and plan for the organization’s talent recruitment and pipeline needs.
Inspire’s growth has required several strategies to attract talent and meet our growth plans, including a strong internal referral network. In addition to sourcing candidates, we also work with search partners as needed. We encourage internal job movement opportunities for employees to support development.
We follow a defined and consistent interview process for open positions, whether internal or external. In order to support our talent attraction efforts, we partner externally with organizations, universities, and colleges to assist with identifying talented pipelines. Internally we continue to build and train hiring managers on a structured interview process to assess talent.
30
Talent Management
We seek to foster a culture where learning is continuous and curiosity and innovation are encouraged. We believe in our people and their ability to accept new responsibilities and challenges, and to grow with us to contribute to our success. Growth is fostered through professional development and learning programs, as well as practical experience leading projects or teams.
New employees joining Inspire are provided with a comprehensive learning path consisting of two key components. First, they gain an understanding of our organization, including our products, the customers and patients we serve, and the regulatory requirements to which we are accountable. Next, training is conducted at the department level to build job role proficiency, and peer mentors may be assigned to help with acceleration of learning and onboarding.
On an ongoing basis, employees have the opportunity to engage in professional development to enhance their Inspire-specific knowledge and skills and their business acumen. These opportunities are available as scheduled in-person events or as just-in-time learning through unlimited access to LinkedIn Learning. Additionally, Inspire offers reimbursement (up to $10,000 per calendar year) for tuition and related expenses.
Developing our leaders is crucial for engagement and business success and we encourage employees to evolve in their roles. An established leadership development pathway supports the growth of our high performers from emerging leaders to effective managers, and further to strengthen coaching and performance management capabilities. Additionally, one-on-one coaching is available for our leaders through external partners.
On an annual basis, our leadership team participates in a talent review and succession planning exercise to identify organizational needs, individual development opportunities, and potential future leaders. This enables us to identify the resources and skill sets needed to meet our growth objectives while encouraging meaningful career and development conversations between leaders and direct reports. We also review pay twice per year for all employees and address any identified gaps.
Inclusion and Belonging
We strive to create a culture in which all employees feel heard, respected, and valued. All new employees participate in training focused on appropriate, respectful, and inclusive workplace behavior. The goals of the training are to encourage broad and diverse viewpoints to achieve the best outcomes for our patients, customers, and employees, and to build awareness of how our own behaviors impact our colleagues.
Charitable Giving
As a medical technology company, we are committed to enhancing the lives of patients through innovation. In 2023, we launched InspireGives, Inspire’s community outreach program aimed at serving the communities in which we live and operate through financial donations and volunteerism. Our contributions seek to provide crucial assistance to charitable organizations striving to treat critical illnesses, combat poverty and homelessness, ease hardship for people affected by disasters, eliminate barriers to equal opportunity, promote healthy sleep, and support underserved communities to address inequities in health outcomes.
Our employees are passionate about improving the lives of others, so we provide channels for our team members to identify opportunities to engage with charitable organizations and events in our communities. In 2025, we contributed nearly $175,000 to local and national charitable organizations including health care charities and charitable organizations addressing other related causes.
Sustainability
As our business continues to grow and develop, we recognize the importance of making responsible business decisions for the benefit of our stakeholders, including our stockholders, customers, employees, partners, the communities in which we work and live, as well as the planet. To that end, we have implemented a corporate sustainability program and set sustainability objectives. We published our fourth Sustainability Report in 2025,
31
which is available on our website, and expect to continue reporting on our progress to our various stakeholders annually.

Item 1A. Risk Factors.
Investing in our common stock involves a high degree of risk. These risks include, but are not limited to, those described below, each of which may be relevant to an investment decision. You should carefully consider the risks described below, together with the other information included or incorporated by reference in this Annual Report on Form 10-K. The realization of any of the following risks could have a significant adverse effect on our reputation, business, financial condition, results of operations, growth, and our ability to accomplish our strategic objectives. In that event, the trading price of our common stock could decline. Other events that we do not currently anticipate or that we currently deem immaterial may also affect our reputation, business, financial conditions, results of operations, growth, and our ability to accomplish our strategic objectives.
Risks Related to Our Business
Our revenue is primarily generated from sales of our Inspire system and we are, therefore, highly dependent on it for our success.
We began selling our Inspire system in 2011 in certain European countries, in 2014 in the U.S., and in 2021 in certain Asia Pacific regions. Sales of our Inspire system accounted for primarily all of our revenue for the years ended December 31, 2025, 2024, and 2023. We expect that sales of our Inspire system will continue to account for the substantial majority of our revenue going forward. Our ability to execute our growth strategy and remain profitable will therefore depend upon the adoption by patients, physicians, and sleep centers, among others, of our Inspire therapy to treat moderate to severe OSA in patients who are unable to use or get consistent benefit from CPAP.
We cannot ensure that our Inspire therapy will achieve or maintain broad market acceptance among physicians and patients. As a single-product company, any failure of the Inspire system to satisfy physician or patient demand or to achieve meaningful market acceptance will harm our business and future prospects.
Our financial results and the market price of our common stock may fluctuate significantly and may not fully reflect the underlying performance of our business.
The market price of our common stock and our quarterly and annual results of operations have in the past and may in the future vary significantly and future period-to-period comparisons of our operating results may not be meaningful. Accordingly, the results of any one quarter or period should not be relied upon as an indication of future performance. The market price of our common stock and our quarterly and annual financial results may fluctuate as a result of a variety of factors, many of which are outside our control and, as a result, may not fully reflect the underlying performance of our business. Such factors may include, for example, seasonal variations in our sales or required postponements of elective surgical procedures effected during a health crisis, as was the
32
case with COVID-19. We generally experience and may in the future experience higher sales in the U.S. during the fourth quarter as a result of patients having paid their annual insurance deductibles in full, thereby reducing their out-of-pocket costs. Alternatively, in the first quarter, many U.S. patients' insurance deductibles reset, requiring more out-of-pocket costs, which negatively impacts our sales during this period.
Other factors that may cause the market price of our common stock to be highly volatile and fluctuations in our quarterly and annual results include, but are not limited to:
•changes in coverage policies by third-party payors that affect the reimbursement of procedures using our products (as well as confusion about potential changes to reimbursement even where no formal change occurs and including any indirect impacts from any changes to provider and patient behavior);
•challenges experienced by patients in obtaining positive coverage and reimbursement decisions from payers, including necessary prior authorization approvals in advance of treatment;
•timing of new product offerings, acquisitions, licenses or other significant events by us or our competitors;
•disputes or other developments with respect to our or others' intellectual property rights;
•patients opting to delay implants of our devices in advance of the commercial launch of new products or product generations;
•unanticipated pricing pressure;
•the hiring, retention, and continued productivity of our sales representatives;
•our ability to expand the geographic reach of our sales and marketing efforts;
•our ability to obtain regulatory clearance, approval, or certification for any products in development or for our current products for additional indications or in additional countries outside the U.S.;
•results of clinical research and studies on our existing products and products in development;
•product liability claims or other litigation;
•changes in earnings estimates or recommendations by securities analysts;
•changes in government regulations;
•delays in receipt of anticipated purchase orders;
•positive or negative coverage in the media or clinical publications of our products or products of our competitors or our industry; and
•general market conditions and other factors, including factors unrelated to our operating performance or the operating performance of our competitors.
Because our quarterly and annual results may fluctuate, period-to-period comparisons may not be the best indication of the underlying results of our business and should only be relied upon as one factor in determining how our business is performing. These fluctuations may also increase the likelihood that we will not meet our forecasted performance, which could negatively affect the market price for our common stock.
In recent years, the stock markets generally have experienced significant price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. Broad market and industry factors may significantly affect the market price of our common stock, regardless of our actual operating performance. In addition, in the past, class action litigation has often been instituted against companies whose
33
securities have experienced periods of volatility in market price. Securities litigation brought against us following volatility in our stock price (including pending litigation, regardless of the merit or ultimate results of such litigation, could result in substantial costs, which would hurt our financial condition and operating results and divert management's attention and resources from our business.
We may not be able to sustain profitability, we have historically incurred significant operating losses, and we may incur operating losses in the future.
The year ended December 31, 2024 was the first year we recorded net income. For the years ended December 31, 2025 and 2024, we recorded net income of $145.4 million and $53.5 million, respectively. Prior to this and since inception, we incurred net losses. For the year ended December 31, 2023, we recorded a net loss of $21.2 million. As of December 31, 2025, we had an accumulated deficit of $146.5 million. To date, we have financed our operations primarily through sales of our Inspire system, private placements of our convertible preferred securities, amounts borrowed under our credit facility, the initial public offering of our common stock that closed in May 2018, and the three follow-on offerings of our common stock that closed in December 2018, April 2020, and August 2022. We have devoted significant resources to research and development activities related to our Inspire system, including clinical and regulatory initiatives to obtain marketing approval, and sales and marketing activities.
Since 2011, our revenue has been derived, and we expect it to continue to be derived, primarily from sales of our Inspire system. Because of its recent commercial introduction, in particular in Thailand and other new markets, our Inspire system has limited product and brand recognition. In addition, demand for our Inspire system may decline or may not increase as quickly as we expect. Our ability to generate revenue from sales of our Inspire system, or from any products we may develop in the future, may not be sufficient to enable us to sustain profitability and generate positive cash flows.
We expect that our operating expenses will continue to increase as we continue to build our commercial infrastructure, invest in research and development, and develop, enhance, and commercialize new products. As a result, even though we achieved profitability in recent years , we may not be able to sustain or increase profitability on an ongoing basis. If we do not sustain profitability, it will be more difficult for us to finance our business and accomplish our strategic objectives, either of which would have a material adverse effect on our business, financial condition, results of operations, and cause the market price of our common stock to decline. In addition, failure of our Inspire system to significantly penetrate existing or new markets would negatively affect our business, financial condition, and results of operations.
If patients or physicians are not willing to change practices to adopt our Inspire therapy to treat moderate to severe OSA, our Inspire therapy may fail to gain increased market acceptance, and our business will be adversely affected.
Our primary strategy to grow our revenue is to drive an increase in the adoption of our Inspire therapy to treat patients with moderate to severe OSA who are unable to use or get consistent benefit from CPAP. While the number of physicians prescribing our Inspire therapy has increased, there is a significant group of physicians who have not yet adopted our Inspire therapy, and additional physicians may choose not to adopt our Inspire therapy for a number of reasons, including, for example:
•lack of availability of adequate or clear third-party payor coverage or reimbursement;
•lack of experience with our products and with upper airway neurostimulation as a treatment alternative;
•our inability to convince key opinion leaders to provide recommendations regarding our Inspire therapy, or to convince physicians, patients, and healthcare payors that our Inspire therapy is an attractive alternative to other treatment options;
•perceived inadequacy of evidence supporting clinical benefits or cost-effectiveness of our Inspire therapy over existing alternatives;
34
•challenges in obtaining prior authorization;
•a perception among some physicians of patients’ inability to tolerate the surgical procedure required to implant our Inspire system;
•liability risks generally associated with the use of new products and procedures; and
•the training required to use new products.
Physicians and other medical professionals commonly screen and treat patients with moderate to severe OSA and are likely to prescribe more conventional second-line treatment methods for patients who are unable to use or obtain consistent benefit from CPAP. We believe that educating physicians in appropriate disciplines and other medical professionals about the clinical merits and patient benefits of our Inspire therapy as a treatment for moderate to severe OSA is a key element of increasing the adoption of our Inspire therapy. If additional physicians or other medical professionals do not adopt, or existing physician customers cease prescribing our Inspire therapy for any reason, including those listed above, our ability to execute our growth strategy will be impaired, and our business may be adversely affected.
In addition, patients may not be able to adopt or may choose not to adopt our Inspire therapy if, among other potential reasons, their airway anatomy would not allow for effective treatment with Inspire therapy, they are reluctant to receive an implantable device as opposed to an alternative, non-implantable treatment, they are worried about potential adverse effects of our Inspire system, such as infection, discomfort from the stimulation or tongue soreness or weakness, or they are unable to obtain adequate third-party coverage or reimbursement.
If we are unable to achieve and maintain adequate levels of coverage or reimbursement for our Inspire system, or any future products we may seek to commercialize, our business, financial condition or results of operations may be adversely affected.
We currently derive all of our revenue from sales of our Inspire system and expect this to continue for the foreseeable future. The primary customers for our products are hospitals and ASCs. Our customers typically bill various third-party payors to cover all or a portion of the costs and fees associated with the procedures in which our products are used and bill patients for any deductibles or co-payments. Because there is often no separate reimbursement for supplies used in surgical procedures, the additional cost associated with the use of our products can affect the profit margin of the hospital or surgery center where the procedure is performed. Some of our target customers may be unwilling to adopt our products in light of the additional associated cost. Further, any decline in the amount payors are willing to reimburse our customers - whether resulting from payor decisions, changes in billing codes, or other factors could make it difficult for existing customers to continue using or to adopt our products and could create additional pricing pressure for us. If we are forced to lower the price we charge for our products, our gross margins will decrease, which could have a material adverse effect on our business, financial condition, and results of operations, and impair our ability to grow our business.
Several third-party payors do not currently cover our products and the related procedures because they have determined that our products and the related procedures are experimental or investigational. When our products and the related procedures are covered, they are reimbursed primarily on a per-patient prior authorization basis for patients covered by commercial insurers, under Local Coverage Determinations for patients covered by Medicare, and under U.S. government contract for patients who are treated by the Veterans Health Administration. Despite prior authorization approvals, it is possible that certain customers who perform the procedure may be subject to reimbursement claim denials upon submission of the claim. Customers may also be subject to recovery of overpayments if a payor makes payment for the claim and subsequently determines that the payor’s coding, billing or coverage policies were not followed.
Third-party payors, whether foreign or domestic, or governmental or commercial, are developing increasingly sophisticated methods of controlling healthcare costs. In addition, no uniform policy of coverage and reimbursement for procedures using our products exists among third-party payors. Therefore, coverage and reimbursement for procedures using our products can differ significantly from payor to payor. Payors continually review new and existing technologies for possible coverage and can, without notice, deny or reverse coverage for
35
new or existing products and procedures. There can be no assurance that third-party payor policies will provide full or meaningful coverage for procedures in which our products are used. If we are not successful in reversing existing non-coverage policies, or if third-party payors that currently cover or reimburse our products and related procedures reverse or limit their coverage in the future, or if other third-party payors issue similar policies, this could have a material adverse effect on our business. Overall, new products and changes in the industry can drive changes to (or a lack of clarity for) reimbursement. Our own products have been billed under different codes and reimbursement approaches throughout our history. Most recently, since the rollout of Inspire V in 2025, there has been confusion and changes (from both government healthcare programs and other payors and parties involved in setting reimbursement and coding) around the appropriate reimbursement and coding for our products that has the potential to adversely impact our revenues, business, financial condition and results of operations. For additional information, see Part I. Item a. "Business - Third-Party Reimbursement - Coding and Payment" and Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Overview.”
Further, we believe that future coverage and reimbursement may be subject to increased restrictions, such as additional prior authorization requirements, both in the U.S. and in international markets. In Europe, reimbursement is entirely regulated at the member state level, varies significantly between member states, and member states are facing increased pressure to limit public healthcare spending. Third-party coverage and reimbursement for procedures using our products or any of our products in development for which we may receive regulatory approval or certification may not be available or adequate in either the U.S. or international markets, which could have an adverse effect on our business, financial condition and results of operations, and impair our ability to grow our business.
We currently compete and will in the future continue to compete against other companies, some of which have longer operating histories, more established products or greater resources than we do, which may prevent us from achieving increased market penetration and improved operating results.
The medical technology and pharmaceutical industries are highly competitive, subject to change and significantly affected by new product introductions and other activities of industry participants. Our competitors have historically dedicated and will continue to dedicate significant resources to promoting their products or drugs or developing new products, drugs or methods to treat moderate to severe OSA.
Our Inspire therapy is approved for use as a second-line therapy in the treatment of moderate to severe OSA in patients who cannot use or obtain consistent benefit from CPAP. If one or more CPAP device manufacturers successfully develop a CPAP device that is more effective, better tolerated or otherwise results in better compliance by patients, or if improvements in other first or second-line therapies make them more effective, cost effective, easier to use or otherwise more attractive than our Inspire therapy, sales of our Inspire system could be significantly and adversely affected, which could have a material adverse effect on our business and financial condition and results of operations. In addition, if other companies are successful in developing neurostimulation devices that are approved for a broader range of indications than our Inspire system, we will be at a further competitive disadvantage, which could also affect our business, financial condition and results of operations. We compete with providers of CPAP or other types of PAP devices, which include, among others, ResMed Inc., Philips BV, Fisher & Paykel Healthcare Corporation Limited, and various regional and new-entrant manufacturers.
Additionally, we compete with various other second-line therapies to treat OSA, including invasive surgical treatment options such as UPPP, MMA, robotic tongue reduction surgery, and, to a lesser extent, oral appliances, which are primarily used in the treatment of mild to moderate OSA. We currently compete in the U.S. and certain countries outside of the U.S. with Nyxoah, which markets an open-loop bilateral hypoglossal nerve stimulation device. We also compete outside the U.S. with LivaNova, which markets an open-loop neurostimulation device and recently announced completion of clinical trials of its device in the U.S. Pharmaceutical therapies to treat OSA are also emerging. Glucagon-like peptide 1 ("GLP-1s"), a class of drug indicated for diabetes and obesity, has continued to gain popularity as a weight-loss drug. In December 2024, the FDA approved the GLP-1 drug Zepbound (tirzepatide) for the treatment of moderate to severe OSA in adults with obesity, and other GLP-1s are currently being clinically evaluated as a potential treatment for OSA. If GLP-1s are successful in treating OSA in an indication for which Inspire therapy is approved, demand for our Inspire system for patients with that indication could be reduced. Although we believe that there could be a benefit to our business as a result of GLP-1s
36
reducing the BMI of our prospective patients and increasing the number of eligible patients for our Inspire therapy, there can be no assurance of such benefit.
In addition, a drug candidate produced by Apnimed is undergoing a Phase 3 clinical trial to assess the viability of its pharmaceutical to treat OSA. We may in the future face competition from pharmaceutical companies that develop similar therapies (other than GLP-1s). We expect to experience increased competition in the future as other companies develop and commercialize competing neurostimulation devices and alternative OSA treatment therapies. Any of these companies may also have the competitive advantages described below.
Many of the companies against which we compete may have competitive advantages with respect to primary competitive factors in the OSA treatment market, including, for example:
•greater company, product, and brand recognition;
•superior product safety, reliability, and durability;
•better quality and larger volume of clinical data;
•more effective marketing to and education of patients, physicians, and sleep centers;
•greater product ease of use and patient comfort;
•more sales force experience and greater market access;
•better product support and service;
•more advanced technological innovation, product enhancements, and speed of innovation;
•more effective pricing and revenue strategies;
•lower procedure costs to patients;
•more effective reimbursement teams and strategies;
•dedicated practice development; and
•more effective clinical training teams.
Most of the other OSA treatments against which we compete have a greater penetration into the OSA treatment market. Oral appliances and other surgical treatments are better known to ENT physicians, sleep centers, and the other physicians on whom we rely for referrals.
We also compete with other medical technology companies to recruit and retain qualified sales, training, and other personnel, including members of our in-house prior authorization team.
We are involved, and may become involved in the future, in disputes and other legal or regulatory proceedings that, if adversely decided or settled, could materially and adversely affect our business, financial condition, and results of operations.
We are, and may in the future become, party to litigation, regulatory proceedings or other disputes. In general, claims made by or against us in disputes and other legal or regulatory proceedings can be expensive and time-consuming to bring or defend against, requiring us to expend significant resources and divert the efforts and attention of our management and other personnel from our business operations. These potential claims may include but are not limited to personal injury and class action lawsuits, data privacy, intellectual property claims and regulatory investigations relating to the advertising and promotional claims about our products and services and employee claims against us based on, among other things, discrimination, harassment or wrongful
37
termination. Any one of these claims may divert our financial and management resources that would otherwise be used to benefit the future performance of our operations. Any adverse determination against us in these proceedings, or even the allegations contained in the claims, regardless of whether they are ultimately found to be without merit, may also result in settlements, injunctions or damages that could have a material adverse effect on our business, financial condition and results of operations.
Additionally, securities class action litigations are often brought against companies following periods of volatility in the overall market and in the market price of a company’s securities. We have experienced these in the past, have such cases pending now and may have such cases in the future. On November 6, 2025, the City of Pontiac Reestablished General Employees’ Retirement System, on behalf of itself and other similarly situated investors, filed a putative securities class action in the United States District Court for the District of Minnesota against the Company and certain of its executive officers, captioned City of Pontiac Reestablished General Employees’ Retirement System v. Inspire Medical Systems, Inc., et al., Case No. 0:25‑cv‑04247‑PJS‑ECW (D. Minn.) (the “City of Pontiac Lawsuit”). The complaint alleged violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Rule 10b‑5 promulgated thereunder, based on purportedly materially false and misleading statements made between August 6, 2024, and August 4, 2025, regarding the launch of the Company’s Inspire V neurostimulator. The complaint further alleged that when subsequent disclosures were made concerning issues with the Inspire V launch and the Company announced its third‑quarter fiscal 2025 results, the Company’s stock price declined, purportedly causing investor losses. On December 23, 2025, the plaintiff filed a Notice of Voluntary Dismissal. On December 29, 2025, the case was administratively closed without prejudice.
On December 22, 2025, the Indiana Public Retirement System, on behalf of itself and other similarly situated investors, filed a putative securities class action in the United States District Court for the Southern District of New York against the Company and certain of its executive officers, captioned Indiana Public Retirement System v. Inspire Medical Systems, Inc., et al., Case No. 1:25‑cv‑10620 (S.D.N.Y.) (the “Indiana PRS Lawsuit”). The Indiana PRS Lawsuit arises from the same underlying subject matter as the City of Pontiac Lawsuit. It alleges the same violations of law and is based on the same or similar purportedly materially false and misleading statements made during the same class period, all of which relate to the launch of the Company’s Inspire V neurostimulator. The plaintiffs seek, among other relief, unquantified compensatory damages, together with attorneys’ fees and costs. On January 22, 2026, the Company and the individual defendants moved to transfer the case to the United States District Court for the District of Minnesota. That motion remains pending. The Company and the individual defendants intend to vigorously defend against the action. No accrual for loss has been accrued or recorded in the Company’s financial statements as of, or for the period ended, December 31, 2025 since the Company is unable to determine whether any loss ultimately will occur or to estimate the range of such loss.
On January 27, 2026, a stockholder derivative lawsuit was filed in the United States District Court for the Southern District of New York, purportedly on behalf of Inspire against certain of our present and former executive officers and against all current members of the Board of Directors and Inspire (as a nominal defendant), captioned Korte v. Herbert., et al., Case No. 1:26‑cv‑680 (S.D.N.Y.). The lawsuit arises out of the same subject matter as the Indiana PRS Lawsuit described above and alleges the following claims: (1) Section 14(a) of the Exchange Act and Rule 14a-9 promulgated thereunder; (2) Section 10(b) of the Exchange Act and Rule 10b-5 promulgated thereunder; (3) Section 20(a) of the Exchange Act; (4) a common-law claim for breach of fiduciary duty; (5) common-law aiding and abetting; (6) unjust enrichment; and (7) waste of corporate assets. The lawsuit seeks unspecified damages. The Company and the individual defendants intend to vigorously defend against the action.
On January 17, 2025, we received a civil investigative demand (“CID”) from the Department of Justice U.S. Attorney’s Office for the District of Minnesota pursuant to the False Claims Act in the course of the government’s investigation concerning allegations of false claims, including false claims arising from violations of the Anti-Kickback Statute, submitted to government payors in connection with our implant. The CID requests information relating to the marketing, promotion and reimbursement practices associated with our products. We are cooperating with the investigation. No assurance can be given as to the timing or outcome of the government’s investigation.
In addition, we are currently a party to multiple adversarial proceedings with Nyxoah regarding our patent portfolio and the patents of third parties. For additional information, see Note 11, Commitments and Contingencies to the
38
consolidated financial statements included elsewhere in this Form 10-K. These lawsuits and any future lawsuits to which we may become a party are subject to inherent uncertainties and could result in very substantial costs, divert our management’s attention and resources and materially harm our business, operating results and financial condition.
Our long-term growth depends on our ability to enhance our Inspire system, expand our indications, and develop and commercialize additional products.
It is important to our business that we continue to enhance our Inspire system and develop and introduce new products. Developing products is expensive and time-consuming and could divert management’s attention away from our core business. The success of any new product offering or product enhancements to our Inspire system will depend on several factors, including our ability to:
•properly identify and anticipate physician and patient needs;
•develop and introduce new products and product enhancements in a timely manner;
•avoid infringing upon the intellectual property rights of third parties;
•demonstrate, if required, the safety and efficacy of new or modified products with data from preclinical studies and clinical studies;
•obtain the necessary regulatory clearances, approvals or certifications for expanded indications, new products or product modifications;
•be fully FDA-compliant with marketing of new or modified devices and be fully compliant with foreign requirements to market our new or modified devices;
•provide adequate training to potential users of our products;
•receive adequate and clear coverage and reimbursement for procedures performed with our products; and
•develop and maintain effective and dedicated sales and marketing team.
If we are not successful in expanding our indications and developing and commercializing new products and product enhancements, our ability to increase our revenue may be impaired, which could have a material adverse effect on our business, financial condition, and results of operations.
Our results of operations could be materially harmed if we are unable to accurately forecast customer demand for our Inspire system and manage our inventory.
So that we have adequate inventory supply, we must forecast inventory needs and place orders with our suppliers based on our estimates of future demand for our Inspire system. Our ability to accurately forecast demand for our Inspire system could be negatively affected by many factors, including, for example, our failure to accurately manage our expansion strategy, product introductions by competitors, an increase or decrease in customer demand for our Inspire system or for products of our competitors, our failure to accurately forecast customer acceptance of new products, customer preferences for new products or new generation products, unanticipated changes in general market conditions or regulatory matters, and weakening of economic conditions or consumer confidence in future economic conditions. Inventory levels in excess of customer demand may result in inventory write-downs or write-offs, which would cause our gross margin to be adversely affected and could impair the strength of our brand. Conversely, if we underestimate customer demand for our Inspire system, our third-party contract manufacturers may not be able to deliver products to meet our requirements, and this could result in damage to our reputation and customer relationships. In addition, if we experience a significant increase in demand, additional supplies of raw materials or additional manufacturing capacity may not be available when required on terms that are acceptable to us, or at all, or suppliers or our third-party manufacturers may not be able
39
to allocate sufficient capacity in order to meet our increased requirements, which could have an adverse effect on our ability to meet customer demand for our Inspire system and our results of operations.
We seek to maintain sufficient levels of inventory in order to protect ourselves from supply interruptions. As a result, we are subject to the risk that a portion of our inventory will become obsolete or expire, which could have a material adverse effect on our earnings and cash flows due to the resulting costs associated with the inventory impairment charges and costs required to replace such inventory.
We have experienced in the past and may experience again in the future supply disruptions. Our efforts to maintain higher levels of inventory to protect ourselves from supply interruptions may not be successful in avoiding significant supply and inventory issues or delay in implant procedures. As a result, we are subject to the risk of inventory obsolescence and expiration, which could lead to inventory impairment charges.
We rely on a limited number of third-party suppliers and contract manufacturers for the manufacture and assembly of our products, and a loss or degradation in performance of these suppliers and contract manufacturers could have a material adverse effect on our business, financial condition, and results of operations.
We rely on third-party suppliers and contract manufacturers for the raw materials and components used in our Inspire system and to manufacture and assemble our products. The suppliers that provide certain materials and components are sole suppliers. These sole suppliers, and any of our other suppliers or our third-party contract manufacturers, may be unwilling or unable to supply the necessary materials and components or manufacture and assemble our products reliably and at the levels we anticipate or that are required by the market. Our ability to supply our products commercially and to develop any future products depends, in part, on our ability to obtain these materials, components, and products in accordance with regulatory requirements and in sufficient quantities for commercialization and clinical testing. We cannot guarantee that our suppliers and contract manufacturers will continue to meet our demand for their products and services on a timely basis or prevent delays in the delivery of their products, which could be adversely affected due to, for example, natural and man-made disasters, public health emergencies, product quality issues, other catastrophic events, the macroeconomic environment including supply chain constraints, higher inflation and interest rates, the nature of our agreements with our contract manufacturers, our relative importance to such manufacturers as a customer or a contract manufacturer's decision to discontinue or reduce the level of business they conduct with us. If we are required to change contract manufacturers due to any change in or termination of our relationships with these third parties, or if our manufacturers are unable to obtain the materials they need to produce our products at consistent prices or at all, we may lose sales, experience manufacturing or other delays, incur increased costs or otherwise experience impairment to our customer relationships. We cannot guarantee that we will be able to establish alternative relationships on similar terms, without delay or at all.
Establishing additional or replacement suppliers for any of these materials, components or services, if required, could be time-consuming and expensive, may result in interruptions in our operations and product delivery, may affect the performance specifications of our Inspire system or could require that we modify its design. Even if we are able to find replacement suppliers or third-party contract manufacturers, we will be required to verify that the new supplier or third-party manufacturer maintains facilities, procedures, and operations that comply with our quality expectations and applicable regulatory requirements. Furthermore, our contract manufacturers could require us to move to another one of their production facilities or use alternative materials or components. Any of these events could require that we obtain a new regulatory authority approval or notified body certification before we implement the change, which could result in further delay and which may not be obtained at all. While we seek to maintain sufficient levels of inventory as discussed above, those inventories may not fully protect us from supply interruptions.
If our third-party suppliers fail to deliver the required commercial quantities of materials on a timely basis and at commercially reasonable prices, and we are unable to find one or more replacement suppliers capable of production at a substantially equivalent cost in substantially equivalent volumes and quality on a timely basis, the continued commercialization of our Inspire system, the supply of our products to customers, and the development of any future products will be delayed, limited or prevented, which could have a material adverse effect on our business, financial condition, and results of operations.
40
Performance issues, service interruptions or price increases by our shipping carriers could adversely affect our business and harm our reputation and ability to provide our services on a timely basis.
Expedited, reliable shipping is essential to our operations. We rely heavily on providers of transport services for reliable and secure point-to-point transport of our Inspire system to our customers and for tracking of these shipments. Should a carrier encounter delivery performance issues such as delivery delays or loss, damage or destruction of any systems, such occurrences may damage our reputation and lead to decreased demand for our Inspire system and increased cost and expense to our business. Similarly, strikes, severe weather, natural disasters, public health crises or other service interruptions affecting delivery services we use would adversely affect our ability to process orders for our Inspire system on a timely basis.
Consolidation in the healthcare industry or group purchasing organizations could lead to demands for price concessions, which may affect our ability to sell our products at prices necessary to support our current business strategies.
Healthcare costs have risen significantly over the past decade, which has resulted in or led to numerous cost reform initiatives by legislators, regulators, and third-party payors. Cost reform has triggered a consolidation trend in the healthcare industry to aggregate purchasing power, which may create more requests for pricing concessions in the future. Additionally, group purchasing organizations, independent delivery networks, and large single accounts may continue to use their market power to consolidate purchasing decisions for hospitals and ASCs. We expect that market demand, government regulation, third-party coverage, and reimbursement policies and societal pressures will continue to change the healthcare industry worldwide, resulting in further business consolidations and alliances among our customers, which may exert further downward pressure on the prices of our products.
If we are unable to effectively size, manage and maintain our direct sales and marketing organization we may not be able to generate revenue growth.
We currently sell our Inspire system through a direct sales force that targets ENT physicians and sleep centers in the U.S., Europe, and Japan, and also utilize various direct-to-consumer marketing initiatives, including paid online search, radio, television, social media, and online videos. In certain Asia Pacific markets, we sell our products through distributors. As of December 31, 2025, our direct sales and marketing organization, including reimbursement personnel, consisted of 954 employees, having increased from 186 employees as of December 31, 2019. Our operating results are directly dependent upon the efforts of these employees. If our direct sales force fails to adequately promote, market and sell our Inspire system, our revenue may be adversely affected.
In order to generate future revenue growth, we plan to continue to expand the size and geographic scope of our direct sales organization. This growth may require us to split or adjust existing sales territories, which may adversely affect our ability to retain customers in those territories. For example, we recently reorganized our sales organization. Additionally, our future success will depend largely on our ability to continue to hire, train, retain, and motivate skilled sales and reimbursement personnel with significant industry experience and technical knowledge of implantable devices and related products. Because the competition for their services is high, we cannot ensure that we will be able to hire and retain additional personnel on favorable or commercially reasonable terms, if at all. Failure to hire or retain qualified sales and reimbursement personnel would prevent us from expanding our business and generating revenue. If we are unable to expand our sales and marketing capabilities, we may not be able to effectively commercialize our Inspire system, which could have an adverse effect on our business, financial condition, and results of operations.
To successfully market and sell our Inspire system in markets outside of the U.S., we must address many international business risks.
Sales in markets outside of the U.S. accounted for approximately 4.4%, 4.0%, and 3.0% of our revenue for the years ended December 31, 2025, 2024, and 2023, respectively. Our strategy is to increase our international presence in Europe, including Germany and the Netherlands, as well as other international markets, such as Japan, Singapore, Hong Kong, and Thailand. This strategy is subject to a number of risks, including:
41
•difficulties in staffing and managing our international operations;
•increased competition as a result of more products and procedures receiving regulatory approval or otherwise free to market in international markets;
•longer accounts receivable payment cycles and difficulties in collecting accounts receivable;
•reduced or varied protection for intellectual property rights in some countries;
•trade export restrictions, trade regulations, and foreign tax laws;
•changing tariffs and trade barriers, including recent and proposed changes in tariffs imposed by the current U.S. presidential administration and any retaliatory tariffs by other countries;
•fluctuations in currency exchange rates;
•foreign certification and regulatory clearance or approval requirements;
•difficulties in developing effective marketing campaigns in unfamiliar foreign countries;
•customs clearance and shipping delays;
•political, social, and economic instability abroad, terrorist attacks, and security concerns in general;
•preference for locally produced products;
•potentially adverse tax consequences, including the complexities of foreign value-added tax systems, tax inefficiencies related to our corporate structure, and restrictions on the repatriation of earnings;
•the burdens of complying with a wide variety of foreign laws and different legal standards;
•unforeseen cultural attitudes that result in fewer potential patients having interest in surgery or a medical device such as our Inspire therapy; and
•increased financial accounting and reporting burdens and complexities.
If one or more of these risks are realized, our business, financial condition, and results of operations could be adversely affected.
We primarily rely on our own direct sales force for our Inspire system, which may result in higher fixed costs than our competitors and may slow our ability to reduce costs in the face of a sudden decline in demand for our products.
We primarily rely on our own direct sales force, which as of December 31, 2025, covered 295 territories in the U.S. and 21 outside of the U.S., to market and sell our Inspire system. Some of our competitors rely predominantly on independent sales agents and third-party distributors. A direct sales force has in the past and may in the future subject us to higher fixed costs than those of companies that market competing products through independent third parties, due to the costs that we bear associated with employee benefits, training, and managing sales personnel. As a result, we could be at a competitive disadvantage. Additionally, these fixed costs may slow our ability to reduce costs in the face of a sudden decline in demand for our Inspire system, which could have a material adverse effect on our business, financial condition, and results of operations.
42
We face the risk of product liability claims that could be expensive, divert management’s attention and harm our reputation and business. We may not be able to maintain adequate product liability insurance.
Our business exposes us to the risk of product liability claims that are inherent in the testing, manufacturing and marketing of medical devices. This risk exists even if a device is cleared, approved, or certified for commercial sale by the FDA or foreign regulatory authorities or notified bodies and manufactured in facilities regulated by the FDA or an applicable foreign regulatory authority. Our Inspire system is designed to affect, and any future products will be designed to affect, important bodily functions and processes. Any side effects, design defects, manufacturing defects, misuse or abuse associated with our Inspire system could result in patient injury or death. The medical device industry has historically been subject to extensive litigation over product liability claims, and we cannot offer any assurance that we will not face product liability suits. We may be subject to product liability claims if our Inspire system causes, or is alleged to have caused, patient injury or death. In addition, an injury that is caused by the activities of our suppliers, such as those who provide us with components and raw materials, may be the basis for a claim against us. Product liability claims may be brought against us by patients, healthcare providers or others selling or otherwise coming into contact with our Inspire system, among others. If we cannot successfully defend ourselves against product liability claims, we will incur substantial liabilities and reputational harm. In addition, regardless of merit or eventual outcome, product liability claims may result in:
•costs of litigation;
•distraction of management’s attention from our primary business;
•the inability to commercialize our Inspire system or new products;
•decreased demand for our Inspire system;
•damage to our business reputation;
•product recalls or withdrawals from the market;
•withdrawal of clinical study participants;
•substantial monetary awards to patients or other claimants; or
•loss of sales.
We can provide no assurance that we will be successful in initiating appropriate market recall or market withdrawal efforts that may be required in the future or that these efforts will have the intended effect of preventing product malfunctions and the accompanying product liability that may result. Such recalls and withdrawals may also be used by our competitors to harm our reputation for safety or be perceived by patients as a safety risk when considering the use of our products, either of which could have a material adverse effect on our business, financial condition and results of operations.
Although we have product liability and clinical study liability insurance, this insurance is subject to deductibles and coverage limitations. Our current product liability insurance may not continue to be available to us on acceptable terms, if at all, and, if available, coverage may not be adequate to protect us against any future product liability claims. If we are unable to obtain insurance at an acceptable cost or on acceptable terms or otherwise protect against potential product liability claims, we could be exposed to significant liabilities. A product liability claim, recall or other claim with respect to uninsured liabilities or for amounts in excess of insured liabilities could have a material adverse effect on our business, financial condition and results of operations.
If the quality of our Inspire system does not meet the expectations of physicians or patients, then our brand and reputation or our business could be adversely affected.
In the course of conducting our business, we must adequately address quality issues that may arise with our Inspire system, including defects in third-party components included in our Inspire system. There can be no
43
assurance that we will be able to eliminate or mitigate occurrences of quality issues and associated liabilities. In addition, even in the absence of quality issues, we may be subject to claims and liability if the performance of our Inspire system does not live up to the expectations of physicians or patients as a result of the patient’s use of the product. For example, battery life will vary based on usage and therapy settings. Based on STAR trial therapy settings at the 12-month endpoint, the battery in our current generation neurostimulator is generally expected to last for approximately 11 years, but it may not last that long if a patient’s use of the device or chosen level of stimulation is greater than expected. The minimum estimated longevity based on STAR trial results is seven years. If the quality of our Inspire system does not meet the expectations of physicians or patients, then our brand and reputation with those physicians or patients, or our business, financial condition and results of operations, could be adversely affected.
If we choose to acquire new and complementary businesses, products or technologies, we may be unable to complete these acquisitions or to successfully integrate them in a cost-effective and non-disruptive manner.
Our success depends, in part, on our ability to continually enhance and broaden our product offerings in response to changing customer demands, competitive pressures and advances in technologies. Accordingly, we may in the future pursue the acquisition of, or joint ventures relating to, complementary businesses, products or technologies instead of developing them ourselves. We do not know if we will be able to successfully complete any future acquisitions or joint ventures, or whether we will be able to successfully integrate any acquired business, product or technology or retain any key employees related thereto. Integrating any business, product or technology we acquire could be expensive and time-consuming, disrupt our ongoing business and distract our management. If we are unable to integrate any acquired businesses, products or technologies effectively, our business will be adversely affected. In addition, any amortization or charges resulting from the costs of acquisitions could increase our expenses.
Unfavorable global economic conditions could adversely affect our business, financial condition or results of operations.
Our results of operations could be adversely affected by general conditions in the global economy and in the global financial markets. Factors such as geopolitical events (including global events like the ongoing wars in Ukraine and Israel), inflationary pressures, public health crises, and U.S. election cycles have caused extreme volatility and disruptions in the capital and credit markets in recent years. Uncertainty or unfavorable global economic conditions could result in a variety of impacts to our business, including weakening demand for our Inspire system, and adversely impacting our ability to raise additional capital when needed on acceptable terms, if at all. A weak or declining economy has strained in the past and may in the future strain our manufacturers or suppliers, possibly resulting in supply disruption, or cause our customers to delay making payments for our services. Further, the current U.S. presidential administration has proposed or enacted tariffs and substantial changes to trade policies, which could adversely affect our business. For example, the current U.S. presidential administration has imposed tariffs on certain foreign products, including most recently from Canada, Mexico and China, that in the past have resulted in and may result in future retaliatory tariffs on U.S. goods and products. We cannot predict whether these policies will continue, or if new policies will be enacted, or the impact, if any, that any policy changes could have on our business. Any of the foregoing could harm our business and we cannot anticipate all of the ways in which the economic climate and financial market conditions could adversely affect our business.
Failure of a key information technology system, process or site, cyberattacks, or other deficiencies in our cybersecurity could have an adverse effect on our business and operations.
We rely extensively on information technology systems to conduct our business and collect, store, process and transmit confidential and sensitive information, including personal information of (or relating to) customers, patients and our employees and contractors. These systems support, among other things, manufacturing and distribution, supply chain management, order processing, financial reporting, patients, regulatory and legal compliance and other critical business functions. Our information technology systems, operational technology environments, and those of our third-party service providers, vendors, contract manufacturers, strategic partners and other contractors or consultants are vulnerable to evolving cybersecurity threats. These threats include, but
44
are not limited to, damage or interruption from computer viruses and malware (e.g. ransomware), misconfigurations, “bugs” or other vulnerabilities, malicious code, terrorism, telecommunication and electrical failures, hacking, cyberattacks, phishing and other social engineering attacks, denial of service attacks, insider threats, human error, fraud, unauthorized access, and attacks by sophisticated nation-state and nation-state-supported actors. We have also outsourced elements of our information technology infrastructure, and as a result a number of third-party vendors may or could have access to our confidential information.
There can be no assurance that our cybersecurity risk management program and processes, including our policies, controls or procedures, will be fully implemented, complied with or effective in protecting our information technology systems and information. The risk of a security breach or disruption, particularly through cyberattacks or cyber intrusion, including by computer hackers, foreign governments and cyber terrorists, has generally increased as the number, intensity and sophistication of attempted attacks and intrusions from around the world have increased and evolved. We and our third-party service providers and partners may also face increased cybersecurity risks due to our reliance on internet technology and employees who work remotely, which may create additional opportunities for cybercriminals to exploit vulnerabilities. Furthermore, because the techniques used to obtain unauthorized access to, or to sabotage, systems change frequently and often are not recognized until launched against a target, we may be unable to anticipate these techniques or implement adequate preventative measures. If we or our third-party vendors were to experience a significant cybersecurity breach of our or their information systems or data, the costs associated with the investigation, remediation and potential notification of the breach to counter-parties and data subjects could be material. In addition, our remediation efforts may not be successful. If we do not allocate and effectively manage the resources necessary to build and sustain the proper technology and cybersecurity infrastructure, we could suffer significant business disruption, including transaction errors, supply chain or manufacturing interruptions, processing inefficiencies, data loss or the loss of or damage to intellectual property or other proprietary information. We may experience security breaches that may remain undetected for an extended period. Even if identified, we may be unable to adequately investigate or remediate incidents or breaches due to attackers increasingly using tools and techniques, including artificial intelligence, that are designed to circumvent controls, to avoid detection, and to remove or obfuscate forensic evidence. Our third-party service providers and partners are also subject to these heightened risks. Because we depend on third-party software components, open-source code, cloud service providers and contract manufacturers to develop, produce and support our products, a cybersecurity incident or vulnerability could introduce security flaws into our products, disrupt manufacturing operations, delay shipments or compromise sensitive data. Overall, if our systems are damaged or cease to function properly due to any number of causes, ranging from catastrophic events to power outages to security breaches we may experience interruptions in our operations, which could have an adverse effect on our business and financial condition.
We and certain of our service providers are from time to time subject to cyberattacks and security incidents. We sell our products to hospitals and healthcare providers, and our devices and monitoring systems may interface with hospital networks and systems that we do not control. Healthcare institutions are frequent targets of cyberattacks, and such an event could impair device connectivity, disrupt patient monitoring, delay therapy delivery or otherwise negatively affect patient care, our customers and our overall reputation. While we do not believe that we have experienced any significant system failure, accident or security breach to date, if such an event were to occur, it could lead to unauthorized access, disclosure and use of confidential information, including personal information from our ADHERE patient registry or other patient information we create, receive, maintain or transmit, including with respect to our Inspire Cloud, SleepSync™ platform, or the Inspire Sleep app, which may be governed by HIPAA and other laws. These mobile applications and cloud-based platforms may be vulnerable to exploitation, authentication failures, data manipulation or unauthorized access. If a security breach or other incident were to result in the unauthorized access to or unauthorized use, disclosure, release or other processing of personal information, it may be necessary to notify individuals, governmental authorities, supervisory bodies, the media and other parties pursuant to privacy and security laws. Any such access, disclosure, or other loss of information could result in regulatory action or investigation, legal claims or proceedings, liability under laws that protect the privacy of personal information, and damage to our reputation, which could materially and adversely affect our business, results of operations or financial condition.
In addition, we accept payments for our sales through credit and debit card transactions, which are handled through a third-party payment processor. As a result, we are subject to a number of risks related to credit and debit card payments. As a result of these transactions, we pay interchange and other fees, which may increase
45
over time and could require us to either increase the prices we charge for our Inspire system or experience an increase in our costs and expenses. In addition, as part of the payment processing process, we transmit our customers’ credit and debit card information to our third-party payment processor. We may in the future become subject to lawsuits or other proceedings for purportedly fraudulent transactions arising out of the actual or alleged theft of our customers’ credit or debit card information if the security of our third-party credit card payment processor is breached. We and our third-party credit card payment processor are also subject to payment card association operating rules, certification requirements and rules governing electronic funds transfers, which could change or be reinterpreted to make it difficult or impossible for us to comply. If we or our third-party credit card payment processor fail to comply with these rules or requirements, we may be subject to fines and higher transaction fees and lose our ability to accept credit and debit card payments from our customers, and there may be an adverse effect on our business.
Our cybersecurity and other insurance coverage involves exclusions and coverage limitations and may not be sufficient to cover the financial, legal, business or reputational losses that may result from a cybersecurity incident or an interruption or breach of our systems.
If our facilities are damaged or become inoperable, we may be unable to continue to research, develop, and supply our Inspire system and, as a result, there could be an adverse effect on our business until we are able to secure a new facility and rebuild our inventory.
We do not have redundant facilities. We perform substantially all of our research and development and back-office activity at two locations in Golden Valley, Minnesota. The majority of our finished goods inventory is maintained at third-party locations in California and North Carolina. Our facility, equipment and inventory would be costly to replace and could require substantial lead time to repair or replace. These facilities may be harmed or rendered inoperable by natural or man-made disasters, including, but not limited to, tornadoes, flooding, fires and other events, including climate change-related severe weather or disasters, power outages, and public health crises, which may render it difficult or impossible for us to perform our research, development and commercialization activities for some period of time. The inability to perform those activities, combined with the time it may take to rebuild our inventory of finished product, may result in the loss of customers or harm to our reputation. Although we possess insurance for damage to our property and the disruption of our business, this insurance may not be sufficient to cover all of our potential losses and this insurance may not continue to be available to us on acceptable terms, or at all.
We rely on third-party distributors to effectively distribute our products in certain markets.
We depend or expect to depend in the future on qualified distributors for the marketing and selling of our products in certain markets. If our distributors fail to effectively market and sell our Inspire system in full compliance with applicable laws, our operating results and business may suffer. Recruiting and retaining qualified third-party distributors and training them in our technology and product offering requires significant time and resources. To develop and expand our distribution, we may be required to scale and improve our processes and procedures that support our distributors. Further, if our relationship with a distributor in a given market terminates, we may be unable to replace that distributor without disruption to our business, or we may decide to transition to a direct sales force in that market. If we fail to develop or maintain positive relationships with our distributors, including in new markets, fail to manage, train or incentivize these distributors effectively, or fail to provide distributors with competitive products on attractive terms, or if these distributors are not successful in their sales efforts, or if we are unable to successfully transition to a direct sales force in markets previously served by distributors, we may not achieve expected revenues or may have a reduction in revenue and our operating results, reputation and business would be harmed.
46
We are subject to anti-bribery, anti-corruption, and anti-money laundering laws, including the U.S. Foreign Corrupt Practices Act, as well as export control laws, customs laws, sanctions laws and other laws governing our operations. If we fail to comply with these laws, we could be subject to civil or criminal penalties, other remedial measures and legal expenses, which could adversely affect our business, results of operations and financial condition.
As we grow our international presence and global operations, we will have increasing obligations to comply with trade and economic sanctions and other restrictions imposed by the U.S., the EU, and other governments and organizations. During the year ended December 31, 2025, approximately 4.4% of our total sales were made in EU member states and certain Asia Pacific regions. The U.S. Departments of Justice, Commerce, State and Treasury and other federal agencies and authorities have a broad range of civil and criminal penalties they may seek to impose against corporations and individuals for violations of economic sanctions laws, export control laws, the U.S. Foreign Corrupt Practices Act ("FCPA") and other federal statutes and regulations, including those established by the Office of Foreign Assets Control ("OFAC"). In addition, the U.K. Bribery Act of 2010 (the "Bribery Act") prohibits both domestic and international bribery, as well as bribery across both private and public sectors. An organization that “fails to prevent bribery” by anyone associated with the organization can be charged under the Bribery Act unless the organization can establish the defense of having implemented “adequate procedures” to prevent bribery. Under these laws and regulations, as well as other anti-corruption laws, anti-money laundering laws, export control laws, customs laws, sanctions laws and other laws governing our operations, various government agencies may require export licenses, may seek to impose modifications to business practices, including cessation of business activities in sanctioned countries or with sanctioned persons or entities and modifications to compliance programs, which may increase compliance costs, and may subject us to fines, penalties and other sanctions. A violation of these laws or regulations would negatively affect our business, financial condition and results of operations.
We have implemented policies and procedures designed to ensure compliance by us and our directors, officers, employees, representatives, consultants and agents with the FCPA, OFAC restrictions, the Bribery Act and other export control, anti-corruption, anti-money-laundering and anti-terrorism laws and regulations. We cannot ensure, however, that our policies and procedures are or will be sufficient or that directors, officers, employees, representatives, consultants and agents have not engaged and will not engage in conduct for which we may be held responsible, nor can we ensure that our business partners have not engaged and will not engage in conduct that could materially affect their ability to perform their contractual obligations to us or even result in our being held liable for such conduct. Violations of the FCPA, OFAC restrictions, the Bribery Act or other export control, anti-corruption, anti-money laundering and anti-terrorism laws or regulations may result in severe criminal or civil sanctions, and we may be subject to other liabilities, which could have a material adverse effect on our business, financial condition and results of operations.
We bear the risk of warranty claims on our Inspire system.
We bear the risk of warranty claims on our Inspire system, which can include defects arising from the design of our products and/or any third-party components. We may not be successful in claiming recovery under any warranty or indemnity provided to us by our suppliers or vendors in the event of a successful warranty claim against us by a customer or that any recovery from such vendor or supplier would be adequate. In addition, warranty claims brought by our customers related to third-party components may arise after our ability to bring corresponding warranty claims against such suppliers expires, which could result in costs to us.
We may need substantial additional funding beyond our existing cash resources and may be unable to raise capital when needed, which could force us to delay or reduce our commercialization efforts or product development programs.
Our estimates and assumptions that support the view that our existing cash, cash equivalents, short-term investments and revenue will be sufficient to meet our capital requirements and fund our operations for at least 12 months may prove to be incorrect, and we could spend our available financial resources much faster than we currently expect. Any future funding requirements will depend on many factors, including:
•patient, physician and market acceptance of our Inspire therapy;
47
•the scope, rate of progress and cost of our current or future clinical studies;
•the cost of our research and development activities;
•the cost of filing and prosecuting patent applications and defending and enforcing our patent or other intellectual property rights;
•the cost of defending, in litigation or otherwise, any claims that we infringe third-party patents or other intellectual property rights;
•the cost and timing of additional regulatory clearances, approvals or certifications;
•the cost and timing of establishing additional sales and marketing capabilities;
•costs associated with any product recall that may occur;
•the effect of competing technological and market developments; and
•the extent to which we acquire or invest in products, technologies and businesses, although we currently have no commitments or agreements relating to any of these types of transactions.
Any additional equity or debt financing that we raise may contain terms that are not favorable to us or our stockholders. If we raise additional funds by selling additional shares of our common stock or other securities convertible into or exercisable or exchangeable for shares of our common stock, the issuance of such securities will result in dilution to our stockholders. The price per share at which we sell additional shares of our common stock, or securities convertible into or exercisable or exchangeable for shares of our common stock, in future transactions may be higher or lower than the price per share paid by investors in previous offerings of shares of our common stock. Furthermore, investors purchasing any securities we may issue in the future may have rights superior to the rights of a holder of our common stock.
In addition, any future debt financing into which we enter may impose upon us covenants that restrict our operations, including limitations on our ability to incur liens or additional debt, pay dividends, repurchase our common stock, make certain investments and engage in certain merger, consolidation or asset sale transactions. If we raise additional funds through collaboration and licensing arrangements with third parties, it may be necessary to relinquish some rights to our technologies or our products, or grant licenses on terms that are not favorable to us.
Furthermore, we cannot be certain that additional funding will be available on acceptable terms, if at all. If we do not have, or are not able to obtain, sufficient funds, we may have to delay development or commercialization of our products or license to third parties the rights to commercialize products or technologies that we would otherwise seek to commercialize. We also may have to reduce marketing, customer support or other resources devoted to our products or cease operations. Any of these factors could harm our business, financial condition and results of operations.
Our ability to use our net operating losses and research and development credit carryforwards to offset future taxable income may be subject to certain limitations.
In general, under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended (the "Code"), a corporation that undergoes an “ownership change,” generally defined as a greater than 50% change by value in its equity ownership over a three-year period, is subject to limitations on its ability to utilize its pre-change net operating losses ("NOLs") and its research and development credit carryforwards to offset future taxable income. During 2025, we finalized a detailed analysis to determine whether an ownership change has occurred through December 31, 2024, and if a limitation exists. It was determined that December 11, 2018 was the only date that we experienced an ownership change. The study concluded that none of the federal net operating losses nor the federal R&D credits that were accumulated on December 11, 2018 will expire unused solely due to the limitations under Sections 382 and 383 of the Code. As of December 31, 2025, our gross federal NOL carryforward was fully
48
utilized and our federal R&D credit carryover was $10.1 million. Future changes in our stock ownership, some of which might be beyond our control, could result in an ownership change under Section 382 of the Code. For these reasons, in the event we experience a change of ownership within the definition of Section 382 of the Code, we may not be able to utilize a material portion of the remaining R&D credit carryforwards, even if we sustain profitability.
Fluctuations in our tax obligations and effective tax rate and realization of our net deferred tax assets may result in volatility of our operating results and materially impact our financial condition or financial results.
We are subject to taxes by the U.S. federal, state, and local tax authorities. We record income tax expense based on our estimates of future payments, which may include the recording of, or adjustments to, liabilities for uncertain tax positions, and changes in the valuation allowance related to our net deferred tax assets. In addition, at any one time multiple tax years may be subject to audit by various tax authorities. The results of these audits and negotiations with taxing authorities may affect the ultimate settlement of these issues and impact our results of operations. We expect that during fiscal year 2026 and beyond there could be ongoing variability in our effective tax rate as events occur and exposures are evaluated. The volatility of our future effective tax rate could be materially impacted by a number of factors, including:
•changes in the valuation of our deferred tax assets and liabilities;
•the tax impact of stock-based compensation awards;
•expected timing and amount of the release of any valuation allowance on our deferred tax assets; or
•changes in U.S. federal, state and local tax rates, tax laws, regulations, or interpretations thereof.
In addition, our effective tax rate in a given financial statement period may be materially impacted by a variety of factors including, but not limited to, changes in the mix and level of earnings, deductible expenses and availability of NOLs in the different states in which we operate, fluctuations in the valuation allowance on our deferred tax assets, or by changes to existing accounting rules or regulations. Further, tax legislation may be enacted or amended, as applicable, in the future which could materially impact our current or future tax structure and effective tax rates. We may be subject to audits of our income, sales, and other transaction taxes by U.S. federal, state, and local taxing authorities. Outcomes from these audits could have a material effect on our financial condition or financial results.
If we were deemed to be an investment company under the Investment Company Act of 1940, as amended (the “1940 Act”), applicable restrictions could make it impractical for us to continue our business as contemplated and could have a material adverse effect on our business, financial condition and results of operations.
Under Sections 3(a)(1)(A) and (C) of the 1940 Act, a company generally will be deemed to be an “investment company” for purposes of the 1940 Act if (1) it is, or holds itself out as being, engaged primarily, or proposes to engage primarily, in the business of investing, reinvesting or trading in securities or (2) it engages, or proposes to engage, in the business of investing, reinvesting, owning, holding or trading in securities and it owns or proposes to acquire investment securities having a value exceeding 40% of the value of its total assets (exclusive of U.S. Treasury debt securities and cash items) on an unconsolidated basis. We do not believe that we are an “investment company,” as such term is defined in either of those sections of the 1940 Act.
We intend to conduct our operations so that we will not be deemed an investment company. However, if we were to be deemed an investment company, restrictions imposed by the 1940 Act, including limitations on our capital structure and our ability to transact with affiliates, could make it impractical for us to continue our business as contemplated and could have a material adverse effect on our business, financial condition and results of operations.
49
The evolving focus on sustainability and environmental, social, and governance initiatives from regulators and stakeholders could increase our costs, expose us to new risks, harm our reputation and adversely impact our financial results.
There has been evolving public focus by investors, customers, activists, the media, politicians, governmental and nongovernmental organizations and other stakeholders on a variety of environmental, social, and governance (“ESG”) matters. We may experience pressure to make commitments relating to ESG matters that affect us, including the design and implementation of specific risk mitigation strategic initiatives relating to ESG. If we are not effective in addressing ESG matters relevant to business, including meeting stakeholder expectations regarding relevant ESG goals, practices, initiatives, commitments, performance and/or public disclosures, our reputation and financial results may suffer. We may experience increased costs in order to execute upon our ESG goals, initiatives, and commitments and measure achievement of those goals, initiatives, and commitments which could have an adverse impact on our business and financial condition. Moreover, the evolving attention to corporate ESG initiatives could also result in reduced demand for products, reduced profits, and increased investigations and litigation. In addition, both advocates for and opponents of ESG matters are increasingly resorting to a range of activism forms, including media campaigns, shareholder proposals, and litigation, to advance their perspectives. There has similarly been an increase in activism, litigation and government enforcement in opposition to certain ESG or human capital management initiatives, such as alleging that corporate diversity, equity and inclusion programs may discriminate against certain groups. To the extent we are subject to such activism or enforcement, it may require us to incur costs or otherwise adversely impact our business.
In addition, organizations that provide information to investors on corporate governance and related matters have developed ratings processes for evaluating companies on ESG matters. Such ratings are used by some investors to inform their investment or voting decisions. Unfavorable ESG ratings could lead to negative investor sentiment toward us and/or our industry, which could have a negative impact on our access to and costs of capital. To the extent ESG matters negatively impact our reputation, we may also not be able to compete as effectively to recruit or retain employees.
This emphasis on ESG matters has resulted and may result in the adoption of new and varied laws and regulations, including reporting requirements. For example, the State of California adopted broad climate reporting laws that may require certain businesses to report on information including greenhouse gas emissions and climate-related financial risk, which are subject to legal challenges. To the extent the California rules are upheld, or we become subject to these or similar federal, state, or local rules, we could face increased costs.
As we continue to focus on our ESG goals, initiatives, commitments, performance, and disclosures, and as ESG-related laws, regulations, and voluntary and required disclosure standards and frameworks continue to evolve, we have expanded our public disclosures in these areas. Such disclosures may reflect goals, aspirations, commitments, and other expectations and assumptions, which are necessarily uncertain and may not be realized. If we fail to comply with new laws or regulations or accurately disclose against voluntary or required reporting standards or frameworks, our reputation and business could be adversely impacted.
Climate-related events, geopolitical and global events, and other events could harm our business.
Natural disasters, disease outbreaks and pandemics, power shortages, terrorism, political unrest, telecommunications failure, vandalism, geopolitical instability, war, climate-related events, and other events beyond our control could negatively impact our operations or otherwise harm our business. Such events may result in damage or loss of service to assets that our operations rely on, cause delays in product development or availability, or result in losses of critical data, any of which may adversely impact our operations.
In addition, the impacts of climate-related events on the global economy and our industry are rapidly evolving. Physical impacts of climate-related events (including but not limited to floods, droughts, more frequent and/or intense storms and wildfires), or chronic changes (such as droughts, heat waves or sea level changes) in climate patterns can adversely impact our operations, as well as the operations of our suppliers and customers. Our facilities and offices may be adversely impacted by natural disasters, including those intensified by climate change. Our locations, and those of our customers and suppliers, can be disrupted by droughts, extreme
50
temperatures, fires, flooding and other climate change-related risks, as well as earthquakes, actions by utility providers, and other catastrophic events such as an actual or threatened public health emergency. If a catastrophic event occurs at or near any of our offices, or utility providers or public health officials take certain actions (e.g., shut off power to our facilities), our operations may be interrupted, which could adversely impact our business and results of operations. If a catastrophic event impacts a significant number of our suppliers or customers, or our customers' ability to perform DISE procedures, implant our Inspire system, or perform related procedures, our business and results of operations could be adversely impacted. For example, in the wake of hurricanes during September and October 2024, our customers experienced delays and shortages of certain products that were necessary to complete DISE procedures and the implant procedure for our Inspire system. These disruptions caused some customers to limit or postpone surgical procedures or elective procedures performed at their facilities, including DISE procedures and implantations of our Inspire system. Our customers have experienced similar disruptions as result of the wildfires in California. These disruptions have caused some customers to limit or postpone surgical procedures or elective procedures at their facilities, including DISE procedures and implantations of our Inspire system. Longer-term physical impacts may also result in changing consumer preferences, which may adversely impact demand for certain of our products. Transition impacts of climate-related events may subject us to increased regulations, reporting requirements, standards or expectations regarding the environmental impacts of our business. Failure to disclose accurate climate-related events information in a timely manner may also adversely affect our reputation, business, or financial performance.
Risks Related to Government Regulation
Our products and operations are subject to extensive and changing laws, government regulation and oversight both in the U.S. and abroad, and our failure to comply with applicable requirements could harm our business.
We and our products are subject to extensive and changing laws, governmental mandates (such as executive orders) and regulation in the U.S. and elsewhere, including by the FDA and its foreign counterparts. Compliance with these laws, regulations and governmental mandates executive orders may be onerous and expensive. New and changing laws, regulations, and governmental mandates could adversely affect our business by increasing our costs, limiting the Company’s ability to pursue or offer a product or product candidate, or by requiring changes to our business. New and changing laws, regulations, and governmental mandates could also create uncertainty about how such laws and regulations will be interpreted and applied. Regulatory changes and other actions that materially adversely affect our business may be announced with little or no advance notice, and we may be unable to timely or successfully mitigate all adverse impacts from such measures. Differing interpretations of such legal obligations could also expose us to significant fines, government investigations, litigation and reputational harm.
Currently, the FDA and foreign regulatory agencies regulate, among other things, with respect to medical devices: design, development and manufacturing; testing, labeling, content and language of instructions for use and storage; clinical studies; product safety; establishment registration and device listing; marketing, sales and distribution; pre-market clearance, approval, and certification; record keeping procedures; advertising and promotion; recalls and field safety corrective actions; post-market surveillance, including reporting of deaths or serious injuries and malfunctions that, if they were to recur, could lead to death or serious injury; post-market approval studies; and product import and export.
The regulations to which we are subject are complex and have tended to become more stringent over time. The FDA, foreign regulatory authorities, and notified bodies enforce these regulatory requirements through periodic unannounced inspections or audits. Failure to comply with applicable regulations could jeopardize our ability to sell our products and result in enforcement actions such as: warning letters; fines; injunctions; civil penalties; termination of distribution; recalls or seizures of products; delays in the introduction of products into the market; total or partial suspension of production; refusal to grant future clearances, approval, or certifications; withdrawals or suspensions of current approvals or certifications, resulting in prohibitions on sales of our products; and in the most serious cases, criminal penalties.
51
If we are found to have violated laws, regulations, or governmental mandates, it could materially and adversely affect our business, reputation, results of operations and financial condition.
We may not receive the necessary approvals or certifications for our future products or expanded indications, and failure to timely obtain necessary approvals or certifications for our future products or expanded indications would adversely affect our ability to grow our business and our results of operations.
An element of our strategy is to continue to upgrade our products, add new features and expand the indications and uses for our current products. In the U.S., before we can market a new medical device, or a new use of, or claim for, or significant modification to, an existing product, we must first receive PMA from the FDA. In the process of obtaining PMA, which was required for our Inspire system, the FDA must determine that a proposed device is safe and effective for its intended use based, in part, on extensive data, including, but not limited to, technical, pre-clinical, clinical study, manufacturing and labeling data. The PMA process is typically required for devices that are deemed to pose the greatest risk, such as life-sustaining, life-supporting or implantable devices.
The process of obtaining a PMA is costly and more uncertain and time consuming than the 510(k) clearance process used for lower risk devices. Despite the time, effort and cost, a device may not be approved by the FDA. Any delay or failure to obtain necessary regulatory approvals could harm our business and results of operations. Furthermore, even if we are granted regulatory approval, it may include significant limitations on the indicated uses for the device, which may limit the market for the device.
The FDA and other regulatory authorities or notified bodies outside the U.S. can delay, limit or deny approval or certification of a device for many reasons, including:
•our inability to demonstrate to the satisfaction of the FDA or the applicable foreign regulatory entity or notified body that our products are safe or effective for their intended uses;
•the disagreement of the FDA or the applicable foreign regulatory authority or notified body with the design or implementation of our clinical studies or the interpretation of data from pre-clinical studies or clinical studies;
•serious and unexpected adverse device effects experienced by participants in our clinical studies;
•the data from our pre-clinical studies and clinical studies may be insufficient to support approval or certification, where required;
•our inability to demonstrate that the clinical and other benefits of the device outweigh the risks;
•the manufacturing process or facilities we use may not meet applicable requirements; and
•the potential for policies or regulations of the FDA or applicable foreign regulatory authorities to change significantly in a manner rendering our clinical data or regulatory filings insufficient for clearance, approval or certification.
In addition, the FDA or other regulatory authorities or notified bodies outside the U.S. may change their approval or certification policies, adopt additional regulations or revise existing regulations, or take other actions, which may prevent or delay approval or certification of our future products under development or impact our ability to modify our currently cleared or certified products on a timely basis. Such policy or regulatory changes could impose additional requirements or time delays upon us that could delay our ability to obtain new approvals or certifications, increase the costs of compliance and our operating expenses, adversely impact our revenues or inventory forecasting or restrict our ability to maintain our current approval or certification.
The timing of FDA approval of a next generation product could have a significant impact on the carrying value of the inventory of our previous generation product, and therefore our results of operations.
52
Subject to the transitional provisions, in order to sell our products in EU member states, our products must comply with the general safety and performance requirements of the EU Medical Devices Regulation, which repeals and replaces the EU Medical Devices Directive and the AIMDD. Compliance with these requirements is a prerequisite to be able to affix the CE mark to our products, without which they cannot be sold or marketed in the EU. To demonstrate compliance with the general safety and performance requirements, we must undergo a conformity assessment procedure, which varies according to the type of medical device and its (risk) classification. Except for low-risk medical devices (Class I), where the manufacturer can self-assess the conformity of its products with the general safety and performance requirements (except for any parts which relate to sterility, metrology or reuse aspects), a conformity assessment procedure requires the intervention of a notified body. The notified body would typically audit and examine the technical file and the quality system for the manufacture, design and final inspection of our devices. If satisfied that the relevant product conforms to the relevant general safety and performance requirements, the notified body issues a certificate of conformity, which the manufacturer uses as a basis for its own declaration of conformity. The manufacturer may then apply the CE mark to the device, which allows the device to be placed on the market throughout the EU. If we fail to comply with applicable laws and regulations, we would be unable to affix the CE mark to our products, which would prevent us from selling them within the EU. The aforementioned EU rules are generally applicable in the EEA, and non-compliance with the above requirements would also prevent us from selling our products in these three countries.
Modifications to our products or manufacturing processes may require us to obtain new PMAs or approvals of a PMA supplement or certification, and if we market modified products without obtaining necessary approvals or certifications, we may be required to cease marketing or recall the modified products until required approvals are obtained.
Certain modifications to a PMA-approved device, or its manufacturing process, may require approval of a new PMA or a PMA supplement, or alternatively a notification or other submission to the FDA. The FDA may not agree with our decisions regarding whether a new PMA or PMA supplement is necessary. We may make modifications to our approved devices in the future that we believe do not require approval of a new PMA or PMA supplement. If the FDA disagrees with our determination and requires us to submit a new PMA or PMA supplement for modifications to our previously approved products, we may be required to cease marketing or to recall the modified product until we obtain approval, and we may be subject to significant regulatory fines or penalties. In addition, the FDA may not approve our products for the indications that are necessary or desirable for successful commercialization or could require clinical studies to support any modifications. Similar requirements may apply in foreign jurisdictions where we market our products. Any delay or failure in obtaining required approvals or certifications would adversely affect our ability to introduce new or enhanced products in a timely manner, which in turn would harm our future growth.
Once devices are certified under the EU Medical Devices Regulation, we must inform the notified body that carried out the conformity assessment of the medical devices that we market or sell in the EU and the EEA of any planned substantial changes to our quality system or substantial changes to our medical devices that could affect compliance with the general safety and performance requirements laid down in Annex I to the EU Medical Devices Regulation or cause a substantial change to the intended use for which the device has been CE marked. The notified body will then assess the planned changes and verify whether they affect the products’ ongoing conformity with the EU Medical Devices Regulation. If the assessment is favorable, the notified body will issue a new certificate of conformity or an addendum to the existing certificate attesting compliance with the general safety and performance requirements and quality system requirements laid down in the Annexes to the EU Medical Devices Regulation. The notified body may disagree with our proposed changes or take more time than anticipated to review and assess applications resulting in regulatory delays. For example, we experienced this between 2021 and 2024 with regard to our application for certification of silicone-based leads under the relevant EU Medical Devices Regulation. See Part I., "Item 1A. Risk Factors — Risks Related to Government Regulation”.
Failure to comply with post-marketing regulatory requirements could subject us to enforcement actions, including substantial penalties, and might require us to recall or withdraw a product from the market.
Even though we have obtained approval for the Inspire system, we are subject to ongoing and pervasive regulatory requirements governing, among other things, the manufacture, marketing, advertising, medical device reporting, sale, promotion, registration, and listing of devices. For example, we must submit periodic reports to the
53
FDA as a condition of PMA. These reports include safety and effectiveness information about the device after its approval. Failure to submit such reports, or failure to submit the reports in a timely manner, could result in enforcement action by the FDA. Following its review of the periodic reports, the FDA might ask for additional information or initiate further investigation. Similar requirements may apply in foreign jurisdictions where we market our products.
In addition, the PMA for our Inspire system was subject to several conditions of approval, including a post-market long-term study. Though we believe we have complied with these conditions to date, any failure to comply with the conditions of approval could result in the withdrawal of PMA and the inability to continue to market the device. Failure to conduct the required studies in accordance with IRB and informed consent requirements, or adverse findings in these studies, could also be grounds for withdrawal of approval of the PMA.
The regulations to which we are subject are complex and have become more stringent over time. Regulatory changes could result in restrictions on our ability to continue or expand our operations, higher than anticipated costs, or lower than anticipated sales. Even after we have obtained the proper regulatory approval or certification to market a device, we have ongoing responsibilities under FDA regulations and applicable foreign laws and regulations. The FDA, state and foreign regulatory authorities have broad enforcement powers. Our failure to comply with applicable regulatory requirements could result in enforcement action by the FDA, state or foreign regulatory authorities, which may include any of the following sanctions:
•untitled letters or warning letters;
•fines, injunctions, consent decrees and civil penalties;
•recalls, termination of distribution, administrative detention, or seizure of our products;
•customer notifications or repair, replacement or refunds;
•operating restrictions or partial suspension or total shutdown of production;
•delays in or refusal to grant our requests for future PMAs or foreign regulatory approvals or certifications of new products, new intended uses, or modifications to existing products;
•withdrawals or suspensions of our current PMA or foreign regulatory approvals or certifications, resulting in prohibitions on sales of our products;
•FDA refusal to issue certificates to foreign governments needed to export products for sale in other countries; and
•criminal prosecution.
Any of these sanctions could result in higher than anticipated costs or lower than anticipated sales and have a material adverse effect on our reputation, business, financial condition and results of operations.
Our products must be manufactured in accordance with foreign, federal and state regulations, and we or any of our suppliers or third-party manufacturers could be forced to recall our installed systems or terminate production if we fail to comply with these regulations.
The methods used in, and the facilities used for, the manufacture of our products must comply with the FDA’s Quality Management System Regulation ("QSMR") which directly incorporates ISO 13485 by reference to cover procedures and documentation of the design, testing, production, process controls, quality assurance, labeling, packaging, handling, storage, distribution, installation, servicing and shipping of medical devices. Furthermore, we are required to verify that our suppliers maintain facilities, procedures and operations that comply with our quality standards and applicable regulatory requirements. The FDA enforces the QSMR through periodic announced or unannounced inspections of medical device manufacturing facilities, which may include the facilities of
54
subcontractors. Our products are also subject to similar state regulations and various laws and regulations of foreign countries governing manufacturing.
Our third-party manufacturers may not take the necessary steps to comply with applicable regulations, which could cause delays in the delivery of our products. In addition, failure to comply with applicable FDA and foreign requirements or later discovery of previously unknown problems with our products or manufacturing processes could result in, among other things: warning letters or untitled letters; fines, injunctions or civil penalties; suspension or withdrawal of approvals or certifications; seizures or recalls of our products; total or partial suspension of production or distribution; administrative or judicially imposed sanctions; the FDA’s or applicable foreign regulatory authority's or notified body's refusal to grant pending or future clearances, approvals or certifications for our products; clinical holds; refusal to permit the import or export of our products; and criminal prosecution of us or our employees.
Any of these actions could significantly and negatively affect supply of our products. If any of these events occur, our reputation could be harmed, we could be exposed to product liability claims and we could lose customers and experience reduced sales and increased costs.
The misuse or off-label use of our Inspire system may harm our reputation in the marketplace, result in injuries that lead to product liability suits or result in costly investigations, fines or sanctions by regulatory bodies if we are deemed to have engaged in the promotion of these uses, any of which could be costly to our business.
Our Inspire system has been approved by the FDA for specific indications. We train our marketing personnel and direct sales force to not promote our Inspire system for uses outside of the FDA-approved indications for use, known as “off-label uses.” We cannot, however, prevent a physician from using our Inspire system off-label, when in the physician’s independent professional medical judgment he or she deems it appropriate. There may be increased risk of injury to patients if physicians attempt to use our Inspire system off-label. Furthermore, the use of our Inspire system for indications other than those approved by the FDA, approved by any foreign regulatory authority or certified by a notified body, may not effectively treat such conditions, which could harm our reputation in the marketplace among physicians and patients.
If the FDA or any foreign regulatory authority determines that our promotional materials or training constitute promotion of an off-label use, it could request that we modify our training or promotional materials or subject us to regulatory or enforcement actions, including the issuance or imposition of an untitled letter, which is used for violators that do not necessitate a warning letter, injunction, seizure, civil fine or criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action under other regulatory authority, such as false claims laws, if they consider our business activities to constitute promotion of an off-label use, which could result in significant penalties, including, but not limited to, criminal, civil and administrative penalties, damages, fines, disgorgement, exclusion from participation in government healthcare programs and the curtailment of our operations.
In addition, physicians may misuse our Inspire system or use improper techniques if they are not adequately trained, potentially leading to injury and an increased risk of product liability. If our Inspire system is misused or used with improper technique, we may become subject to costly litigation by our customers or their patients. Similarly, in an effort to decrease costs, physicians may also reuse our Inspire system despite it being intended for a single use or may purchase reprocessed Inspire systems from third-party reprocessors in lieu of purchasing a new Inspire system from us, which could result in product failure and liability. As described above, product liability claims could divert management’s attention from our core business, be expensive to defend and result in sizable damage awards against us that may not be covered by insurance.
55
Our products may cause or contribute to adverse medical events or be subject to failures or malfunctions that we are required to report to the FDA and foreign regulatory authorities, and if we fail to do so, we would be subject to sanctions that could harm our reputation, business, financial condition and results of operations. The discovery of serious safety issues with our products, or a recall of our products either voluntarily or at the direction of the FDA or another governmental authority, could have a negative impact on us.
We are subject to the FDA’s medical device reporting regulations and similar foreign regulations, which require us to report to the FDA and foreign regulatory authorities. In the U.S., information that reasonably suggests that one or more of our products may have caused or contributed to a death or serious injury or malfunctioned in a way that, if the malfunction were to recur, it could cause or contribute to a death or serious injury must be reported to the FDA. The timing of our obligation to report is triggered by the date we become aware of the adverse event as well as the nature of the event. We may fail to report adverse events of which we become aware within the prescribed timeframe. We may also fail to recognize that we have become aware of a reportable adverse event, especially if it is not reported to us as an adverse event or if it is an adverse event that is unexpected or removed in time from the use of the product. If we fail to comply with our reporting obligations, the FDA and foreign regulatory authorities could take action, including warning letters, untitled letters, administrative actions, criminal prosecution, imposition of civil monetary penalties, revocation of our device approval or certification, seizure of our products or delay in clearance, approval or certification of future products.
The FDA and foreign regulatory bodies have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacture of a product or in the event that a product poses an unacceptable risk to health. The FDA’s and foreign regulatory bodies' authority to require a recall must be based on a finding that there is reasonable probability that the device could cause serious adverse health consequences or death. We may also choose to voluntarily recall a product if any material deficiency is found. A government-mandated or voluntary recall by us could occur as a result of an unacceptable risk to health, component failures, malfunctions, manufacturing defects, labeling or design deficiencies, packaging defects or other deficiencies or failures to comply with applicable regulations. Product defects or other errors may occur in the future.
Depending on the corrective action we take to redress a product’s deficiencies or defects, the FDA or foreign regulatory authorities may require, or we may decide, that we will need to obtain new approvals for the device before we may market or distribute the corrected device. Seeking such approvals may delay our ability to replace the recalled devices in a timely manner. Moreover, if we do not adequately address problems associated with our devices, we may face additional regulatory enforcement action, including FDA or foreign regulatory authority warning letters, product seizure, injunctions, administrative penalties or civil or criminal fines.
Companies are required to maintain certain records of recalls and corrections, even if they are not reportable to the FDA or foreign regulatory authorities. We may initiate voluntary withdrawals or corrections for our products in the future that we determine do not require notification to the FDA or foreign regulatory authorities. If the FDA or a foreign regulatory authority disagrees with our determinations, it could require us to report those actions as recalls and we may be subject to enforcement action. A future recall announcement could harm our reputation with customers, potentially lead to product liability claims against us and negatively affect our sales. Any corrective action, whether voluntary or involuntary, as well as defending ourselves in a lawsuit, will require the dedication of our time and capital, distract management from operating our business and may harm our reputation and financial results.
If we do not obtain and maintain international regulatory registrations, approvals or certifications for our products, we will be unable to market and sell our products outside of the U.S.
Sales of our products outside of the U.S. are subject to foreign regulatory requirements that vary widely from country to country. In addition, the FDA regulates exports of medical devices from the U.S. While the regulations of some countries may not impose barriers to marketing and selling our products or only require notification, others require that we obtain the approval of or certification by a specified body (e.g., notified bodies in Europe). Complying with foreign regulatory requirements, including obtaining registrations, approvals or certifications, can be expensive and time-consuming, and we may not receive regulatory approvals or certifications in each country
56
in which we plan to market our products or we may be unable to do so on a timely basis. The time required to obtain registrations, approvals or certifications, if required by other countries, may be longer than that required for FDA approval, and requirements for such registrations, clearances, approvals or certifications may significantly differ from FDA requirements. If we modify our products, we may need to apply for additional regulatory approvals or certifications before we are permitted to sell the modified product. In addition, we may not continue to meet the quality and safety standards required to maintain the authorizations or certifications that we have received. If we are unable to maintain our authorizations or certifications in a particular country, we will no longer be able to sell the applicable product in that country.
Regulatory approval by the FDA does not ensure registration, clearance, approval or certification by regulatory authorities or notified bodies in other countries, and registration, clearance, approval or certification by one or more foreign regulatory authorities or notified bodies does not ensure registration, clearance, approval or certification by regulatory authorities or notified bodies in other foreign countries or by the FDA. However, a failure or delay in obtaining registration, regulatory clearance, approval or certification in one country may have a negative effect on the regulatory process in others.
The FDA may modify its enforcement policies with respect to medical software products, and our software products may become subject to extensive regulatory requirements, which may increase the cost of conducting, or otherwise harm, our business.
We develop and offer certain software applications in connection with our business, including our SleepSync™ cloud-based patient management platform, which is designed to function as a medical device data system (“MDDS”). For its part, the FDA may regulate medical or health-related software, including clinical decision support software, machine learning functionality and predictive algorithms, if such software falls within the definition of a “medical device” under the FDCA. However, historically, the FDA has exercised enforcement discretion for certain low-risk software functions, and has issued several guidance documents that establish enforcement discretion policies and/or otherwise outline the FDA’s approach to the regulation of software as a medical device. For example, in September 2022 the FDA issued a guidance entitled: “Medical Device Data Systems, Medical Image Storage Devices, and Medical Image Communications Devices,” which among other things, announced the FDA’s intent not to enforce compliance with certain FDCA requirements with respect to medical device MDDS functions, including those requirements relating to registration and listing, premarket review, post-market reporting and compliance with the QMSR.
In addition, the 21st Century Cures Act ("Cures Act”) amended the FDCA to exclude from the definition of “medical device” certain medical-related software, including certain software used for administrative support functions at a healthcare facility, software intended for maintaining or encouraging a healthy lifestyle, software designed to store electronic health records, certain clinical decision support software, and software for transferring, storing, or displaying medical device data or in vitro diagnostic data, including certain MDDS functionality. We believe our currently marketed applications, including the SleepSync™ platform, provide functionality that either qualifies for FDA enforcement discretion under the September 2022 policy for device MDDS, or is otherwise exempt from the FDCA’s definition of a “medical device” pursuant to the Cures Act amendments, and therefore that our products are subject to the FDA’s current enforcement discretion policy applicable to MDDS software functions or otherwise provide functions that are not currently regulated by the FDA as a medical device. However, there is a risk that the FDA could disagree with our determinations, or that the FDA could alter its enforcement discretion policies, and in either case, subject our software to more stringent medical device regulations.
If the FDA determines that any of our current or future software applications, including the SleepSync™ platform, are regulated as medical devices and not otherwise subject to enforcement discretion, we would become subject to various requirements under the FDCA and the FDA’s implementing regulations. If this occurs, we may be required to cease marketing or to recall our software products until we obtain the requisite clearances or approvals, and we may be subject to enforcement action. In addition, as we continue to update and improve our SleepSync™ platform, we are also continuing to integrate certain software functions we utilize for compliance, quality oversight and product surveillance into the SleepSync™ platform. As such, any enforcement action with respect to our SleepSync™ software platform, or any requirements for us to obtain clearances or approvals for our software applications would also affect the speed at which we could update and modify these systems, and in
57
any case, would entail significant cost and could harm our reputation, business, financial condition, and results of operations.
Legislative or regulatory reforms in the U.S. or the EU may make it more difficult and costly for us to obtain regulatory clearances, approvals or certification for our products or to manufacture, market or distribute our products after clearance, approval or certification is obtained.
From time to time, legislation is drafted and introduced in Congress that could significantly change the statutory provisions governing the regulation of medical devices. In addition, FDA regulations and guidance are often revised or reinterpreted by the FDA in ways that may significantly affect our business and our products. Any new statutes, regulations or revisions or reinterpretations of existing regulations may impose additional costs or lengthen review times of any future products or make it more difficult to obtain approval for, manufacture, market or distribute our products.
We cannot determine what effect changes in regulations, statutes, legal interpretation or policies, when and if promulgated, enacted or adopted may have on our business in the future. Such changes could, among other things, require: additional testing prior to obtaining clearance or approval; changes to manufacturing methods; recall, replacement or discontinuance of our products; or additional record keeping. For example, on February 2, 2026, the FDA's final rule implementing the FDA's QMSR became effective. The WMSR, which replaced the FDA's former Quality System Regulation, sets forth the FDA's requirements for medical devices, and among other things, incorporates by reference certain elements of the quality management system requirements of ISO 13485:2016. Although the FDA has stated that the standards contained in ISO 13485:2016 are substantially similar to those set forth in the QMSR, and although our quality management system is designed to comply with ISO 13485, the FDA has indicated that ISO:13485 certification alone will not ensure compliance under the QMSR, nor will ISO certification exempt manufacturers from FDA inspection. The QMSR also includes certain compliance obligations, such as those relating to unique device identification, product traceability, and maintenance of complaint and service records, that align more closely with the FDA’s existing medical device requirements than with ISO standards. Accordingly, it remains unclear the extent to which the QMSR may impose additional or different regulatory requirements on us that could increase the costs of compliance or otherwise negatively affect our business. If we are unable to comply with QMSR or with any other changes in the laws or regulations enforced by FDA or comparable regulatory authorities, we may be subject to enforcement action, which could have an adverse effect on our business, financial condition and results of operations.
Similarly, the EU landscape concerning medical devices recently evolved, and continues to undergo legislative changes. On May 25, 2017, the EU Medical Devices Regulation entered into force, which repeals and replaces the EU Medical Devices Directive and the AIMDD. See Part I, Item I, “Business – Government Regulation” for additional information on these reforms. These requirements are in active implementation and may change as the European Commission adopts additional implementing acts and considers targeted revisions to related medical device rules. In addition, on December 16, 2025, the European Commission published a targeted revision proposal of the MDR to address structural issues, certification delays, and burdens on small and medium-sized enterprises. The proposal will enter the ordinary legislative procedure and is not expected to be adopted before 2027. These modifications are likely to have an effect on the way we conduct our business in the EEA. For example, as a result of the transition towards the new regime, notified body review times have lengthened, and product introductions or modifications could be delayed or canceled, which could adversely affect our ability to grow our business.
We are subject to federal, state and foreign fraud and abuse laws, and transparency laws, which, if violated, could subject us to substantial penalties. Additionally, any challenge to or investigation into our practices under these laws could cause adverse publicity and be costly to respond to, and thus could harm our business.
There are numerous U.S. federal and state, as well as foreign, laws pertaining to healthcare fraud and abuse, including anti-kickback, false claims and physician transparency laws. Our business practices and relationships with providers are subject to scrutiny under these laws. The healthcare laws and regulations that may affect our ability to operate include, but are not limited to: the federal Anti-Kickback Statute, the federal civil and criminal false claims laws and civil monetary penalties laws, including the federal civil False Claims Act, the federal Civil
58
Monetary Penalties Law, federal criminal fraud and abuse laws under HIPAA, analogous state and foreign law equivalents of each of the foregoing. See Part I, Item 1. "Business — Government Regulation."
These laws and regulations, among other things, constrain our business, marketing and other promotional activities by limiting the kinds of financial arrangements, including sales programs, we may have with hospitals, physicians or other potential purchasers of our products. Similar laws may exist in other jurisdictions where we operate, such as in the EU. Due to the breadth of these laws, the narrowness of statutory exceptions and regulatory safe harbors available, and the range of interpretations to which they are subject, it is possible that some of our current or future practices might be challenged under one or more of these laws.
To enforce compliance with the healthcare regulatory laws, certain enforcement bodies have recently increased their scrutiny of interactions between healthcare companies and healthcare providers, which has led to a number of investigations, prosecutions, convictions and settlements in the healthcare industry. For example, on January 17, 2025, we received a CID from the Department of Justice U.S. Attorney’s Office for the District of Minnesota pursuant to the False Claims Act in the course of the government’s investigation concerning allegations of false claims, including false claims arising from violations of the Anti-Kickback Statute, submitted to government payors in connection with our implant. The CID requests information relating to the marketing, promotion and reimbursement practices associated with our products. We are cooperating with the investigation. No assurance can be given as to the timing or outcome of the government’s investigation.
Responding to investigations can be time-and resource-consuming and can divert management’s attention from the business. Additionally, as a result of these investigations, healthcare providers and entities may have to agree to additional compliance and reporting requirements as part of a consent decree or corporate integrity agreement. Any such investigation or settlement could increase our costs or otherwise have an adverse effect on our business. Even an unsuccessful challenge or investigation into our practices could cause adverse publicity, and be costly to respond to. If our operations are found to be in violation of any of the healthcare laws or regulations described above or any other healthcare regulations that apply to us, we may be subject to penalties, including administrative, civil and criminal penalties, damages, fines, exclusion from participation in government healthcare programs, such as Medicare and Medicaid, imprisonment, contractual damages, reputational harm, disgorgement and the curtailment or restructuring of our operations.
We are or may be subject to U.S. federal, state, and foreign laws and regulations which impose obligations on how we collect, store and process health-related and other personal information. Our actual or perceived failure to comply with such obligations could harm our business, operations, and financial condition. Ensuring compliance with such laws could also impair our efforts to maintain and expand our customer base, and thereby decrease our revenue.
In the conduct of our business, we process health-related and other personal information. The U.S. federal government, various states, and foreign governments have adopted or proposed laws, regulations, guidelines and rules for the collection, distribution, use and storage of personal information of individuals. For example, HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, and regulations implemented thereunder (collectively "HIPAA"), imposes privacy, security and breach notification obligations on certain healthcare providers, health plans, and healthcare clearinghouses, known as covered entities, as well as their business associates that perform certain services that involve creating, receiving, maintaining or transmitting individually identifiable health information for or on behalf of such covered entities, and their covered subcontractors. HIPAA requires covered entities and business associates to develop and maintain policies with respect to the protection of, use and disclosure of protected health information ("PHI"), including the adoption of administrative, physical and technical safeguards to protect such information, and certain notification requirements in the event of a breach of unsecured PHI.
Entities that are found to be in violation of HIPAA as the result of a breach of unsecured PHI, a complaint about privacy practices or an audit by the U.S. Department of Health and Human Services ("HHS"), may be subject to significant civil, criminal and administrative fines and penalties and/or additional reporting and oversight obligations. HIPAA also authorizes state Attorneys General to file suit on behalf of their residents. Courts may award damages, costs and attorneys’ fees related to violations of HIPAA in such cases. While HIPAA does not create a private right of action allowing individuals to sue us in civil court for violations of HIPAA, its standards
59
have been used as the basis for duty of care in state civil suits such as those for negligence or recklessness in the misuse or breach of PHI.
Further, the Federal Trade Commission (the "FTC") and many state Attorneys General continue to enforce federal and state consumer protection laws against companies for online collection, use, dissemination and security practices that appear to be unfair or deceptive. For example, according to the FTC, failing to take appropriate steps to keep consumers’ personal information secure can constitute unfair acts or practices in or affecting commerce in violation of Section 5(a) of the Federal Trade Commission Act. The FTC expects a company’s data security measures to be reasonable and appropriate in light of the sensitivity and volume of consumer information it holds, the size and complexity of its business, and the cost of available tools to improve security and reduce vulnerabilities.
We may also be subject to U.S. federal rules, regulations, and guidance concerning data security for medical devices, including guidance from the FDA. State privacy and security laws which govern the privacy, processing and protection of health-related and other personal information vary from state to state and, in some cases, can impose more restrictive requirements than U.S. federal law. Where state laws are more protective, we must comply with the stricter provisions. In addition to fines and penalties that may be imposed for failure to comply with state law, some states also provide for private rights of action to individuals for certain misuses of personal information. For example, the California Consumer Privacy Act of 2018, as amended by the California Privacy Rights Act (collectively, the "CCPA") requires covered businesses that process the personal information of California residents to, among other things: (i) provide certain disclosures to California residents regarding the business’s collection, use, and disclosure of their personal information; (ii) receive and respond to requests from California residents to access, delete, and correct their personal information, or to opt out of certain disclosures of their personal information; and (iii) enter into specific contractual provisions with service providers that process California resident personal information on the business’s behalf. Similar laws have passed in other states, and are continuing to be proposed at the state and federal level, reflecting a trend toward more stringent privacy legislation in the U.S. The enactment of such laws could have potentially conflicting requirements that would make compliance challenging and additional compliance investment and potential business process changes may be required.
We also expect that there will continue to be new laws, regulations and industry standards concerning privacy, data protection and information security proposed and enacted in various jurisdictions. For example, Washington State enacted a broadly applicable law to protect the privacy of personal health information known as the “My Health My Data Act,” which generally requires affirmative consent for the collection, use, or sharing of any “consumer health data.” Consumer health data is defined to include personal information that is linked or reasonably linkable to a consumer and that identifies a consumer’s past, present, or future physical or mental health status; consumer health data also includes information that is derived or extrapolated from non-health information, such as algorithms and machine learning. Other states, including Connecticut and Nevada, have also passed consumer health data laws, and given the increased focus on the use of health data by entities that are not subject to HIPAA, additional states are expected to pass consumer health privacy laws. In the event that we are subject to or affected by new and/or existing privacy and data protection laws, any liability from failure to comply with the requirements of these laws could adversely affect our financial condition.
We are also or may become subject to rapidly evolving data protection laws, rules and regulations in foreign jurisdictions. For example, in Europe, we are subject to the requirements of the General Data Protection Regulation ("GDPR") (and national laws implementing the GDPR) because we are “established” in certain EU countries and we are processing personal data of individuals located in the EU and EEA in the context of these establishments, as well as offering of goods to, and/or monitoring the behavior of, individuals in the EU and EEA in connection with our clinical investigations and commercial technical support activities. The GDPR, which went into effect in May 2018, imposes strict requirements for processing the personal data subject to the GDPR. If we do not comply with our obligations under the GDPR, we could be exposed to significant fines the greater of EUR 20 million or 4% of total global annual turnover for certain breaches. In addition to the foregoing, a breach of the GDPR could result in regulatory investigations, reputational damage, orders to cease/ change our use of data, enforcement notices, as well potential civil claims including class action type litigation where individuals suffer harm.
60
Among other requirements, the GDPR regulates transfers of personal data subject to the GDPR to third countries that have not been found to provide adequate protection to such personal data, including the United States. Recent legal developments in Europe have created complexity and uncertainty regarding such transfers, in particular in relation to transfers to the United States, and the efficacy and longevity of current transfer mechanisms between the EEA, and the United States remains uncertain. Case law from the Court of Justice of the European Union (“CJEU”) states that reliance on the standard contractual clauses (SCCs) (a standard form of contract approved by the European Commission as an adequate personal data transfer mechanism) alone may not necessarily be sufficient in all circumstances and that transfers must be assessed on a case-by-case basis. We expect the existing legal complexity and uncertainty regarding international personal data transfers to continue. As supervisory authorities issue further guidance on personal data export mechanisms, including circumstances where the standard contract clauses cannot be used, and/or start taking enforcement action, we could suffer additional costs, complaints and/or regulatory investigations or fines, and/or if we are otherwise unable to transfer personal data between and among countries and regions in which we operate, it could affect the manner in which we provide our services, the geographical location or segregation of our relevant systems and operations, and could adversely affect our financial results.
Further, from January 1, 2021, we have to comply with both the GDPR and the GDPR as incorporated into United Kingdom national law, under the United Kingdom General Data Protection Regulation and Data Protection Act 2018 (collectively, the “UK GDPR”) which imposes separate but similar fines up to the greater of £17.5 million or 4% of global turnover. On October 12, 2023, the UK Extension to the DPF came into effect (as approved by the UK Government), as a UK GDPR data transfer mechanism to U.S. entities self-certified under the UK Extension to the DPF.
We are also subject to evolving EU and EEA privacy laws on cookies and e-marketing. In the EU and the UK, informed consent is required for the placement of certain cookie or similar technologies on an individual’s device and for direct electronic marketing. The GDPR also imposes conditions on obtaining valid consent for cookies, such as a prohibition on pre-checked consents and a requirement to ensure separate consents are sought for each type of cookie or similar technology. Recent European court and regulator decisions and guidance are driving increased attention to cookies and tracking technologies. If the trend of increasing enforcement by regulators of the strict approach to opt-in consent for all but essential use cases, as seen in recent guidance and decisions continues, this could lead to substantial costs, require significant systems changes, limit the effectiveness of our marketing activities, divert the attention of our technology personnel, adversely affect our margins, and subject us to additional liabilities. In light of the complex and evolving nature of EU, EU Member State, and UK privacy laws on cookies and tracking technologies, there can be no assurances that we will be successful in our efforts to comply with such laws; violations of such laws could result in regulatory investigations, fines, orders to cease/ change our use of such technologies, as well as civil claims including class actions, and reputational damage.
Our efforts to comply with applicable laws, regulations and standards, our contractual obligations and other legal obligations may be unsuccessful. Further, these requirements are evolving and may be modified, interpreted and applied in an inconsistent manner from one jurisdiction to another, and may conflict with one another or other legal obligations with which we must comply. Any actual or perceived failure by us, our employees or contractors, our partners, our service providers, or the third parties with whom we work, to comply with privacy or security laws, policies, legal obligations or industry standards, or any security incident that results in the unauthorized release or transfer of personal information, may result in governmental enforcement actions and investigations including by EU regulators and U.S. federal and state regulatory authorities as well as fines and penalties, litigation, including by consumer advocacy groups, and/or adverse publicity and could cause our customers, their patients and other healthcare professionals to lose trust in us, which could harm our reputation and have a material adverse effect on our business, financial condition and results of operations.
Our business may be affected by the evolving regulatory framework for AI Technologies.
The regulatory framework for artificial intelligence (“AI”), machine learning, and automated decision-making technologies (collectively, “AI Technologies”) is rapidly evolving as many federal, state, and foreign government bodies and agencies have introduced or are currently considering additional laws and regulations. Additionally, existing laws and regulations may be interpreted in ways that would affect the operation of our AI Technologies.
61
It is possible that new laws and regulations will be adopted in the United States and in other non-U.S. jurisdictions, or that existing laws and regulations, including competition and antitrust laws, may be interpreted in ways that would limit our ability to use AI Technologies for our business, or require us to change the way we use AI Technologies in a manner that negatively affects the performance of our products, services, and business and the way in which we use AI Technologies. We may need to expend resources to adjust our products or services in certain jurisdictions if the laws, regulations, or decisions are not consistent across jurisdictions. Further, the cost to comply with such laws, regulations, or decisions and/or guidance interpreting existing laws, could be significant and would increase our operating expenses (such as by imposing additional reporting obligations regarding our use of AI Technologies). Such an increase in operating expenses, as well as any actual or perceived failure to comply with such laws and regulations, could adversely affect our business, financial condition and results of operations.
Current and future healthcare reform legislation or regulation may increase the difficulty and cost for us to commercialize our products and could harm our business, financial condition and results of operations.
In the U.S., there have been and continue to be a number of legislative initiatives to contain healthcare costs, and there is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality and/or expanding access. We expect that current laws, as well as other healthcare reform measures that may be adopted in the future, may result in more rigorous coverage criteria and in additional downward pressure on the price that we may receive for our product. New and changing laws and regulations may also create uncertainty about how such laws and regulations will be interpreted and applied. If we are found to have violated laws and regulations, it could materially adversely affect our business, results of operations and financial condition.
In 2010, the Affordable Care Act (the "ACA") was enacted in the U.S., which made a number of substantial changes in the way healthcare is financed by both governmental and private insurers. Among the provisions of the ACA of importance to our business are the following:
•a new Patient-Centered Outcomes Research Institute to oversee and identify priorities in comparative clinical effectiveness research in an effort to coordinate and develop such research;
•payment system reforms including a national pilot program on payment bundling to encourage hospitals, physicians and other providers to improve the coordination, quality and efficiency of certain healthcare services through bundled payment models; and
•expanded the eligibility criteria for Medicaid programs.
In addition, other legislative changes have been proposed and adopted since the ACA was enacted, such as the Budget Control Act of 2011, the American Taxpayer Relief Act of 2012, and the Medicare Access and CHIP Reauthorization Act of 2015, among others. The expansion in the government’s role in the U.S. healthcare industry may result in decreased profits to us, lower reimbursement by payors for our Inspire system, and/or reduced medical procedure volumes, all of which may have a material adverse effect on our business, financial condition and results of operations. A recent example is the WISeR Model initiated by CMS. See Part I, Item 1. “Business — Government Regulation.”
The One Big Beautiful Bill Act, which was enacted in July 2025, imposes significant reductions in the funding of the Medicaid program. Such reductions are expected to decrease the number of persons enrolled in Medicaid and reduce the services covered by Medicaid, which could adversely affect sales of our Inspire system.
We expect additional state, federal, and foreign healthcare policies and reform measures to be adopted in the future, any of which could limit reimbursement for healthcare products and services or otherwise result in reduced demand for our Inspire system or additional pricing pressure and have a material adverse effect on our industry generally and on our customers. Any changes of, or uncertainty with respect to, future coverage or reimbursement rates could affect demand for our Inspire system, which in turn could impact our ability to successfully
62
commercialize our Inspire system and could have a material adverse effect on our business, financial condition and results of operations.
Our business involves the use of hazardous materials and our third-party manufacturers must comply with environmental laws and regulations, which may be expensive and restrict how we do business.
Our third-party manufacturers’ activities may involve the controlled storage, use and disposal of hazardous materials, including for example batteries. Our manufacturers are subject to federal, state, local, and foreign laws and regulations governing the use, generation, manufacture, storage, handling and disposal of these hazardous materials. We currently carry no insurance specifically covering environmental claims relating to the use of hazardous materials. Although we believe the safety procedures of our manufacturers for handling and disposing of these materials and waste products comply with the standards prescribed by these laws and regulations, we cannot eliminate the risk of accidental injury or contamination from the use, storage, handling or disposal of hazardous materials. In the event of an accident, state or federal or other applicable authorities may curtail our manufacturers’ use of these materials and interrupt their business operations which could adversely affect our business. Environmental laws and regulations could change or become more stringent over time, imposing greater compliance costs, and increasing risks and penalties associated with violations. We cannot assure you that violations of these laws and regulations will not occur in the future or have not occurred in the past as a result of human error, accidents, equipment failure or other causes. The expense associated with environmental regulation and remediation could harm our business, financial condition, and results of operations.
The clinical study process required to obtain regulatory approvals or certifications is lengthy and expensive with uncertain outcomes. If clinical studies of our future products do not produce results necessary to support regulatory clearance or approval in the U.S. or foreign approval or certification, with respect to our current or future products, elsewhere, we will be unable to expand the indications for or commercialize these products and may incur additional costs or experience delays in completing, or ultimately be unable to complete, the commercialization of those products.
We have obtained PMA for our Inspire system. In order to obtain PMA for a device or to obtain approval of certain PMA supplements, the device sponsor must conduct well-controlled clinical studies designed to assess the safety and efficacy of the product candidate. Conducting clinical studies is a complex and expensive process, can take many years, and outcomes are inherently uncertain. We incur substantial expense for, and devote significant time to, clinical studies but cannot be certain that the studies will ever result in commercial revenue. We may experience significant setbacks in clinical studies, even after earlier clinical studies showed promising results, and failure can occur at any time during the clinical study process. Any of our products may malfunction or may produce undesirable adverse effects that could cause us or regulatory authorities to interrupt, delay or halt clinical studies.
We will likely need to conduct additional clinical studies in the future to support new indications for our products or for approvals, clearances or certifications of new product lines, or for the approval of the use of our products in some foreign countries. Clinical testing is difficult to design and implement, can take many years, can be expensive and carries uncertain outcomes. The initiation and completion of any of these studies may be prevented, delayed, or halted for numerous reasons. We may experience a number of events during that could adversely affect the costs, timing or successful completion of our clinical studies, including:
•we may be required to submit an IDE application or similar application to the FDA or a foreign regulatory authority, which must become effective prior to commencing human clinical studies, and the FDA or foreign regulatory authority may reject our IDE or similar application and notify us that we may not begin investigational studies;
•regulators and other comparable foreign regulatory authorities may disagree as to the design or implementation of our clinical studies;
•regulators and/or IRBs, or other reviewing bodies may not authorize us or our investigators to commence a clinical study, or to conduct or continue a clinical study at a prospective or specific study site;
63
•we may not reach agreement on acceptable terms with prospective contract research organizations ("CROs") and clinical study sites, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and study sites;
•clinical studies may produce negative or inconclusive results, and we may decide, or regulators may require us, to conduct additional clinical studies or abandon product development programs;
•the number of subjects or patients required for clinical studies may be larger than we anticipate, enrollment in these clinical studies may be insufficient or slower than we anticipate, and the number of clinical studies being conducted at any given time may be high and result in fewer available patients for any given clinical study, or patients may drop out of these clinical studies at a higher rate than we anticipate;
•our third-party contractors, including those manufacturing products or conducting clinical studies on our behalf, may fail to comply with regulatory requirements or meet their contractual obligations to us in a timely manner, or at all;
•we might have to suspend or terminate clinical studies for various reasons, including a finding that the subjects are being exposed to unacceptable health risks;
•patients may be harmed in the course of the clinical study negatively impacting Inspire’s brand, reputation, and business;
•we may have to amend clinical study protocols or conduct additional studies to reflect changes in regulatory requirements or guidance, which we may be required to submit to an IRB or other review bodies and/or regulatory authorities for re-examination;
•regulators, IRBs, or other parties may require or recommend that we or our investigators suspend or terminate clinical research for various reasons, including safety signals or noncompliance with regulatory requirements;
•the cost of clinical studies may be greater than we anticipate;
•clinical sites may not adhere to the clinical protocol or may drop out of a clinical study;
•we may be unable to recruit a sufficient number of clinical study sites;
•regulators, IRBs, or other reviewing bodies may fail to approve or subsequently find fault with our manufacturing processes or facilities of third-party manufacturers with which we enter into agreement for clinical and commercial supplies, the supply of devices or other materials necessary to conduct clinical studies may be insufficient, inadequate or not available at an acceptable cost, or we may experience interruptions in supply;
•policies or regulations of FDA or applicable foreign regulatory agencies may change in a manner rendering our clinical data insufficient for approval or certification; and
•our current or future products may have undesirable side effects or other unexpected characteristics.
Patient enrollment in clinical studies and completion of patient follow-up depend on many factors, including the size of the patient population, the nature of the study protocol, the proximity of patients to clinical sites, the eligibility criteria for the clinical study, patient compliance, competing clinical studies and clinicians’ and patients’ perceptions as to the potential advantages of the product being studied in relation to other available therapies, including any new treatments that may be approved for the indications we are investigating. For example, patients may be discouraged from enrolling in our clinical studies if the study protocol requires them to undergo extensive post-treatment procedures or follow-up to assess the safety and efficacy of a product candidate, or they may be persuaded to participate in contemporaneous clinical studies of a competitor’s product candidate. In addition,
64
patients participating in our clinical studies may drop out before completion of the study or experience adverse medical events unrelated to our products. Delays in patient enrollment or failure of patients to continue to participate in a clinical study may delay commencement or completion of the clinical study, cause an increase in the costs of the clinical study and delays, or result in the failure of the clinical study.
Clinical studies must be conducted in accordance with the laws and regulations of the FDA and other applicable regulatory authorities’ legal requirements, regulations or guidelines, and are subject to oversight by these governmental agencies and IRBs and other reviewing bodies at the medical institutions where the clinical studies are conducted. In addition, clinical studies must be conducted with supplies of our devices produced under current good manufacturing practice requirements and other regulations. Furthermore, we rely on CROs, and clinical study sites to ensure the proper and timely conduct of our clinical studies and while we have agreements governing their committed activities, we have limited influence over their actual performance. We depend on our collaborators and on medical institutions and CROs to conduct our clinical studies in compliance with good clinical practice ("GCP") requirements. To the extent our collaborators or the CROs fail to enroll participants for our clinical studies, fail to conduct the study in accordance with GCP requirements or are delayed for a significant time in the execution of studies, including achieving full enrollment, we may be affected by increased costs, program delays or both. In addition, clinical studies that are conducted in countries outside the U.S. may subject us to further delays and expenses as a result of increased shipment costs, additional regulatory requirements and the engagement of non-U.S. CROs, as well as expose us to risks associated with clinical investigators who are unknown to the FDA, and different standards of diagnosis, screening and medical care.
Failure can occur at any stage of clinical testing. Our clinical studies may produce negative or inconclusive results, and we may decide, or regulators may require us, to conduct additional clinical and non-clinical testing in addition to those we have planned. Our failure to adequately demonstrate the safety and efficacy of our system or any product we may develop in the future would prevent receipt of regulatory clearance, approval or certification and, ultimately, the commercialization of that product or indication for use. Even if our future products are cleared or approved in the U.S., commercialization of our products in foreign countries would require approval by regulatory authorities or certification by notified bodies in those countries. Approval and certification procedures vary among jurisdictions and can involve requirements and administrative review periods different from, and greater than, those in the U.S., including additional preclinical studies or clinical studies. Any of these occurrences could have an adverse effect on our business, financial condition and results of operations.
Disruptions at the FDA, other government agencies or notified bodies caused by funding shortages, staffing limitations, or policy changes could hinder their ability to hire and retain key leadership and other personnel, or otherwise prevent new products and services from being developed or commercialized in a timely manner, which could negatively impact our business.
The ability of the FDA, foreign regulatory authorities and notified bodies to review and approve or certify new products can be affected by a variety of factors, including government budget and funding levels, ability to hire and retain key personnel and accept the payment of user fees, and statutory, regulatory, and policy changes. Average review times at the agency have fluctuated in recent years as a result. In addition, government funding of other government agencies that fund research and development activities is subject to the political process, which is inherently fluid and unpredictable.
Disruptions at the FDA and other agencies or notified bodies may also slow the time necessary for new medical devices and modifications to cleared or approved medical devices to be reviewed and/or cleared, approved or certified by necessary government agencies or notified bodies, which would adversely affect our business. For example, in recent years, the U.S. government has shut down several times and certain regulatory agencies, such as the FDA, have had to furlough critical FDA employees and stop critical activities. If a prolonged government shutdown occurs, it could significantly impact the ability of the FDA to timely review and process our regulatory submissions, which could have a material adverse effect on our business. Similarly, a prolonged government shutdown could prevent the timely review of our patent applications by the United States Patent and Trademark Office ("USPTO"), which could delay the issuance of any U.S. patents to which we might otherwise be entitled. Further, in our operations as a public company, future government shutdowns could impact our ability to access the public markets and obtain necessary capital in order to properly fund our business. In addition, the current U.S. Presidential administration has issued certain policies and Executive Orders directed towards reducing the
65
employee headcount and costs associated with U.S. administrative agencies, including the FDA, and it remains unclear the degree to which these efforts may limit or otherwise adversely affect such agencies’ ability to conduct routine activities.
In the EU, notified bodies must be officially designated to certify products and services in accordance with the EU Medical Devices Regulation. Their designation process, which is significantly stricter under the new Regulation, has experienced considerable delays in recent years. Despite a recent increase in designations, the current number of notified bodies designated under the new Regulation remains significantly lower than the number of notified bodies designated under the previous regime. The current designated notified bodies are therefore facing a backlog of requests as a consequence of which review times have lengthened. This situation may impact the way we are conducting our business in the EU and the EEA and the ability of our notified body to timely review and process our regulatory submissions and perform its audits.
Risks Related to Intellectual Property Matters
If we are unable to adequately protect our intellectual property rights, or if we are accused of infringing on the intellectual property rights of others, our competitive position could be harmed or we could be required to incur significant expenses to enforce or defend our rights.
Our commercial success depends in part on our success in obtaining and maintaining issued patents, trademarks and other intellectual property rights in the U.S. and elsewhere and protecting our proprietary technology. If we do not adequately protect our intellectual property and proprietary technology, competitors may be able to use our technologies or the goodwill we have acquired in the marketplace and erode or negate any competitive advantage we may have, which could harm our business and ability to sustain profitability.
We own numerous issued patents and pending patent applications that relate to our system. As of December 31, 2025, we had rights to 119 issued U.S. patents, 83 issued foreign patents, 73 pending U.S. patent applications, and 73 pending foreign patent applications. Assuming all required fees are paid, issued U.S. patents owned by us will expire between 2029 and 2043.
We cannot provide any assurances that any of our patents have, or that any of our pending patent applications that mature into issued patents will include, claims with a scope sufficient to protect our Inspire system, any additional features we develop for our Inspire system or any new products. Other parties may have developed technologies that may be related or competitive to our system, may have filed or may file patent applications and may have received or may receive patents that overlap or conflict with our patent applications, either by claiming the same methods or devices or by claiming subject matter that could dominate our patent position. The patent positions of medical device companies, including our patent position, may involve complex legal and factual questions, and, therefore, the scope, validity and enforceability of any patent claims that we may obtain cannot be predicted with certainty. Patents, if issued, may be challenged, deemed unenforceable, invalidated or circumvented. Proceedings challenging our patents could result in either loss of the patent or denial of the patent application or loss or reduction in the scope of one or more of the claims of the patent or patent application. In addition, such proceedings may be costly. Thus, any patents that we may own may not provide any protection against competitors. Furthermore, an adverse decision in an interference proceeding can result in a third party receiving the patent right sought by us, which in turn could affect our ability to commercialize our products.
Though an issued patent is presumed valid and enforceable, its issuance is not conclusive as to its validity or its enforceability and it may not provide us with adequate proprietary protection or competitive advantages against competitors with similar products. Competitors could purchase our Inspire system and attempt to replicate some or all of the competitive advantages we derive from our development efforts, willfully infringe our intellectual property rights, design around our patents, or develop and obtain patent protection for more effective technologies, designs or methods. We may be unable to prevent the unauthorized disclosure or use of our technical knowledge or trade secrets by consultants, suppliers, vendors, former employees and current employees. The laws of some foreign countries do not protect our proprietary rights to the same extent as the laws of the U.S., and we may encounter significant problems in protecting our proprietary rights in these countries.
66
Our ability to enforce our patent rights depends on our ability to detect infringement. It may be difficult to detect infringers who do not advertise the components that are used in their products. Moreover, it may be difficult or impossible to obtain evidence of infringement in a competitor’s or potential competitor’s product. We may not prevail in any lawsuits that we initiate and the damages or other remedies awarded if we were to prevail may not be commercially meaningful.
In addition, proceedings to enforce or defend our patents could put our patents at risk of being invalidated, held unenforceable or interpreted narrowly. Such proceedings could also provoke third parties to assert claims against us, including that some or all of the claims in one or more of our patents are invalid or otherwise unenforceable. If any of our patents covering our Inspire system are invalidated or found unenforceable, or if a court found that valid, enforceable patents held by third parties covered one or more of our products, our competitive position could be harmed or we could be required to incur significant expenses to enforce or defend our rights.
The degree of future protection for our proprietary rights is uncertain, and we cannot ensure that:
•any of our patents, or any of our pending patent applications, if issued, will include claims having a scope sufficient to protect our Inspire system;
•any of our pending patent applications will issue as patents;
•we will be able to successfully commercialize our products on a substantial scale, if approved, before our relevant patents we may have expire;
•we were the first to make the inventions covered by each of our patents and pending patent applications;
•we were the first to file patent applications for these inventions;
•others will not develop similar or alternative technologies that do not infringe our patents; any of our patents will be found to ultimately be valid and enforceable;
•any patents issued to us will provide a basis for an exclusive market for our commercially viable products, will provide us with any competitive advantages or will not be challenged by third parties;
•we will develop additional proprietary technologies or products that are separately patentable; or
•our commercial activities or products will not infringe upon the patents of others.
We rely, in part, upon unpatented trade secrets, unpatented know-how and continuing technological innovation to develop and maintain our competitive position, which we seek to protect, in part, by confidentiality agreements with our employees and our collaborators and consultants. We also have agreements with our employees and consultants that obligate them to assign their inventions to us and have non-compete agreements with some, but not all, of our consultants. It is possible that technology relevant to our business will be independently developed by a person that is not a party to such an agreement. Furthermore, if the employees and consultants who are parties to these agreements breach or violate the terms of these agreements, we may not have adequate remedies for any such breach or violation, and we could lose our trade secrets through such breaches or violations. Further, our trade secrets could otherwise become known or be independently discovered by our competitors.
Litigation or other proceedings or third-party claims of intellectual property infringement could require us to spend significant time and money and could prevent us from selling our products or affect our stock price.
Our commercial success may depend in part on allegations from third parties alleging that we are infringing their patents or violating their other proprietary rights. Significant litigation regarding patent rights occurs in our industry. Our competitors in both the U.S. and abroad, many of which have substantially greater resources and have made substantial investments in patent portfolios and competing technologies, may have applied for or obtained or may
67
in the future apply for and obtain, patents that will prevent, limit or otherwise interfere with our ability to make, use and sell our products. We may not always be aware of all patents and published applications, and patent applications in the U.S. and elsewhere can be pending for many years before issuance, or unintentionally abandoned patents or applications can be revived, so there may be applications of others now pending or recently revived patents of which we are unaware. These applications may later result in issued patents, or the revival of previously abandoned patents, that will prevent, limit or otherwise interfere with our ability to make, use or sell our products. Third parties may, in the future, assert claims that we are employing their proprietary technology without authorization, including claims from competitors or from non-practicing entities that have no relevant product revenue and against whom our own patent portfolio may have no deterrent effect. As we continue to commercialize our products in their current or updated forms, launch new products and enter new markets, competitors may claim that one or more of our products infringe their intellectual property rights as part of business strategies designed to impede our successful commercialization and entry into new markets. The large number of patents, the rapid rate of new patent applications and issuances, the complexities of the technology involved, and the uncertainty of litigation may increase the risk of business resources and management’s attention being diverted to patent litigation. We have, and we may in the future, receive letters or other threats or claims from third parties inviting us to take licenses under, or alleging that we infringe, their patents.
Moreover, we may become party to future adversarial proceedings regarding our patent portfolio or the patents of third parties. Such proceedings could include supplemental examination or contested post-grant proceedings such as review, reexamination, inter partes review, interference or derivation proceedings before the USPTO and challenges in U.S. District Court. Patents may be subjected to opposition, post-grant review or comparable proceedings lodged in various foreign, both national and regional, patent offices. The legal threshold for initiating litigation or contested proceedings may be low, so that even lawsuits or proceedings with a low probability of success might be initiated. Litigation and contested proceedings can also be expensive and time-consuming, and our adversaries in these proceedings may have the ability to dedicate substantially greater resources to prosecuting these legal actions than we can. We may also occasionally use these proceedings to challenge the patent rights of others. We cannot be certain that any particular challenge will be successful in limiting or eliminating the challenged patent rights of the third party. In May 2025, we filed a lawsuit against Nyxoah in the United States District Court for the District of Delaware, alleging that Nyxoah's Genio product infringes on certain of our U.S. patents related to neurostimulation therapy for obstructive sleep apnea. We are seeking a judgment of patent infringement and relief for such infringement, including monetary damages such as lost profits. Nyxoah has denied infringement and has asserted counterclaims seeking declaratory judgments of invalidity and non‑infringement. Nyxoah subsequently filed a lawsuit in September 2025 against us in the United States District Court for the District of Delaware alleging that our Inspire IV and Inspire V implantable neurostimulators infringe certain of Nyxoah’s patents. Additionally, in December 2025, Nyxoah brought suit against us and our wholly-owned subsidiary, Inspire Medical Systems Europe GmbH in the Unified Patent Court, Munich Division, alleging that the Inspire IV implantable neurostimulator infringes a patent owned by Nyxoah. Also in December 2025, Nyxoah filed three (3) petitions with the United States Patent Trial and Appeal Board seeking inter partes review (IPR) of the three patents asserted by Inspire in the lawsuit.
Any lawsuits resulting from such allegations could subject us to significant liability for damages and invalidate our proprietary rights. Any potential intellectual property litigation also could force us to do one or more of the following:
•stop making, selling or using products or technologies that allegedly infringe the asserted intellectual property;
•lose the opportunity to license our technology to others or to collect royalty payments based upon successful protection and assertion of our intellectual property rights against others; incur significant legal expenses;
•pay substantial damages or royalties to the party whose intellectual property rights we may be found to be infringing;
•pay the attorney’s fees and costs of litigation to the party whose intellectual property rights we may be found to be infringing;
68
•redesign those products that contain the allegedly infringing intellectual property, which could be costly, disruptive or infeasible; and
•attempt to obtain a license to the relevant intellectual property from third parties, which may not be available on reasonable terms or at all, or from third parties who may attempt to license rights that they do not have.
Any litigation or claim against us may cause us to incur substantial costs, and could place a significant strain on our financial resources, divert the attention of management from our core business and harm our reputation. If we are found to infringe the intellectual property rights of third parties, we could be required to pay substantial damages (which a court may, in its discretion, enhance awarded damages up to three times in cases of willful infringement) and/or substantial royalties and could be prevented from selling our products unless we obtain a license or are able to redesign our products to avoid infringement. Any such license may not be available on reasonable terms, if at all, and there can be no assurance that we would be able to redesign our products in a way that would not infringe the intellectual property rights of others. We could encounter delays in product introductions while we attempt to develop alternative methods or products. If we fail to obtain any required licenses or make any necessary changes to our products or technologies, we may have to withdraw existing products from the market or may be unable to commercialize one or more of our products.
In addition, we generally indemnify our customers with respect to infringement by our products of the proprietary rights of third parties. Third parties may assert infringement claims against our customers. These claims may require us to initiate or defend protracted and costly litigation on behalf of our customers, regardless of the merits of these claims. If any of these claims succeed or settle, we may be forced to pay damages or settlement payments on behalf of our customers or may be required to obtain licenses for the products they use. If we cannot obtain all necessary licenses on commercially reasonable terms, our customers may be forced to stop using our products.
If we are unable to protect the confidentiality of our trade secrets, our business and competitive position could be harmed.
In addition to patent protection for our issued patents and pending patent applications related to our system, we also rely upon copyright and trade secret protection for our Inspire therapy, as well as non-disclosure agreements and invention assignment agreements with our employees, consultants and third parties, to protect our confidential and proprietary information. In addition to contractual measures, we seek to protect the confidential nature of our proprietary information using commonly accepted physical and technological security measures. Such measures may not, for example, in the case of misappropriation of a trade secret by an employee or third party with authorized access, provide adequate protection for our proprietary information. Our security measures may not prevent an employee or consultant from misappropriating our trade secrets and providing them to a competitor, and recourse we take against such misconduct may not provide an adequate remedy to protect our interests fully. Unauthorized parties may also attempt to copy or reverse engineer certain aspects of our products that we consider proprietary. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret can be difficult, expensive and time-consuming, and the outcome is unpredictable. Even though we use commonly accepted security measures, trade secret violations are often a matter of state law, and the criteria for protection of trade secrets can vary among different jurisdictions. In addition, trade secrets may be independently developed by others in a manner that could prevent legal recourse by us. If any of our confidential or proprietary information, such as our trade secrets, were to be disclosed or misappropriated, or if any such information was independently developed by a competitor, our business and competitive position could be harmed.
We may be unable to enforce our intellectual property rights throughout the world.
The laws of some foreign countries do not protect intellectual property rights to the same extent as the laws of the U.S. Many companies have encountered significant problems in protecting and defending intellectual property rights in certain foreign jurisdictions. This could make it difficult for us to stop infringement of our foreign patents, if obtained, or the misappropriation of our other intellectual property rights. For example, some foreign countries have compulsory licensing laws under which a patent owner must grant licenses to third parties. In addition, some countries limit the enforceability of patents against third parties, including government agencies or government
69
contractors. In these countries, patents may provide limited or no benefit. Patent protection must ultimately be sought on a country-by-country basis, which is an expensive and time-consuming process with uncertain outcomes. Accordingly, we may choose not to seek patent protection in certain countries, and we will not have the benefit of patent protection in such countries.
Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business. Accordingly, our efforts to protect our intellectual property rights in such countries may be inadequate. In addition, changes in the law and legal decisions by courts in the U.S. and foreign countries may affect our ability to obtain adequate protection for our technology and the enforcement of our intellectual property.
Third parties may assert ownership or commercial rights to inventions we develop.
Third parties may in the future make claims challenging the inventorship or ownership of our intellectual property. We have written agreements with collaborators that provide for the ownership of intellectual property arising from our collaborations. In addition, we may face claims by third parties that our agreements with employees, contractors or consultants obligating them to assign intellectual property to us are ineffective or in conflict with prior or competing contractual obligations of assignment, which could result in ownership disputes regarding intellectual property we have developed or will develop and interfere with our ability to capture the commercial value of such intellectual property. Litigation may be necessary to resolve an ownership dispute, and if we are not successful, we may be precluded from using certain intellectual property or may lose our exclusive rights in that intellectual property. Either outcome could harm our business and competitive position.
Third parties may assert that our employees or consultants have wrongfully used or disclosed confidential information or misappropriated trade secrets.
We employ individuals who previously worked with other companies, including our competitors or potential competitors. Although we seek to ensure that our employees and consultants do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that we or our employees, consultants or independent contractors have inadvertently or otherwise used or disclosed intellectual property or personal information, including trade secrets or other proprietary information, of a former employer or other third party. Litigation may be necessary to defend against these claims. If we fail in defending any such claims or settling those claims, in addition to paying monetary damages or a settlement payment, we may lose valuable intellectual property rights or personnel. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to management and other employees.
Changes in U.S. and foreign patent laws may limit our ability to obtain, defend and/or enforce our patents.
Patent reform legislation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents in the U.S. and abroad. The Leahy-Smith America Invents Act ("the Leahy-Smith Act") includes a number of significant changes to U.S. patent law. These include provisions that affect the way patent applications are prosecuted and also affect patent litigation. The USPTO recently developed new regulations and procedures to govern administration of the Leahy-Smith Act, and many of the substantive changes to patent law associated with the Leahy-Smith Act, and in particular, the first to file provisions, which became effective on March 16, 2013. The first to file provisions limit the rights of an inventor to patent an invention if not the first to file an application for patenting that invention, even if such invention was the first invention. Accordingly, it is not clear what, if any, impact the Leahy-Smith Act will have on the operation of our business.
However, the Leahy-Smith Act and its implementation could increase the uncertainties and costs surrounding the enforcement and defense of our issued patents. For example, the Leahy-Smith Act provides that an administrative tribunal known as the Patent Trial and Appeals Board ("PTAB") provides a venue for challenging the validity of patents at a cost that is much lower than district court litigation and on timelines that are much faster. Although it is not clear what, if any, long-term impact the PTAB proceedings will have on the operation of our business, the initial results of patent challenge proceedings before the PTAB since its inception have resulted in the invalidation of many U.S. patent claims. The availability of the PTAB as a lower-cost, faster and potentially more potent
70
tribunal for challenging patents could increase the likelihood that our own patents will be challenged, thereby increasing the uncertainties and costs of maintaining and enforcing them.
In addition, implementation of the European Patent Package, or EU Patent Package, occurred on June 1, 2023. Under a new European Unified Patent Court, or the UPC, all European patents, including those issued prior to ratification of the European Patent Package, will by default automatically fall under the jurisdiction of the UPC. The UPC will provide parties with a new forum to centrally revoke our European patents, and allow for the possibility of a competitor to obtain pan-European injunctions. Such a loss of patent protection could have a material adverse impact on our business and our ability to commercialize our technology and product candidates and, resultantly, on our business, financial condition, prospects and results of operations. Under the EU Patent Package as currently proposed, we will have the right to opt our patents out of the UPC over the first seven years of the court’s existence, but doing so may preclude us from realizing the benefits of the new unified court. Moreover, if we do not meet all of the formalities and requirements for opt-out under the UPC, our future European patents could remain under the jurisdiction of the UPC.
Risks Related to Our Common Stock
Provisions in our governing documents and under Delaware law could make an acquisition of us more difficult and may prevent attempts by our stockholders to replace or remove our current management.
Provisions in our amended and restated certificate of incorporation and our amended and restated bylaws may discourage, delay or prevent a merger, acquisition or other change in control of us that stockholders may consider favorable, including transactions in which stockholders might otherwise receive a premium for their shares. These provisions could also limit the price that investors might be willing to pay in the future for shares of our common stock, thereby depressing the market price of our common stock. In addition, these provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors. Because our board of directors is responsible for appointing the members of our management team, these provisions could in turn affect any attempt by our stockholders to replace current members of our management team. These provisions provide, among other things, that:
•our board of directors has the exclusive right to expand the size of our board of directors and to elect directors to fill a vacancy created by the expansion of the board of directors or the resignation, death or removal of a director, which prevents stockholders from being able to fill vacancies on our board of directors;
•our board of directors is divided into three classes, Class I, Class II and Class III, with each class serving staggered three-year terms, which may delay the ability of stockholders to change the membership of a majority of our board of directors;
•our stockholders may not act by written consent, which forces stockholder action to be taken at an annual or special meeting of our stockholders;
•a special meeting of stockholders may be called only by the chair of our board of directors, our chief executive officer or a majority of our board of directors, which may delay the ability of our stockholders to force consideration of a proposal or to take action, including the removal of directors;
•our amended and restated certificate of incorporation prohibits cumulative voting in the election of directors, which limits the ability of minority stockholders to elect director candidates;
•our board of directors may alter certain provisions of our bylaws without obtaining stockholder approval;
•the approval of the holders of at least two-thirds of the shares entitled to vote at an election of directors is required to adopt, amend or repeal our bylaws or repeal the provisions of our amended and restated certificate of incorporation regarding the election and removal of directors;
71
•stockholders must provide advance notice and additional disclosures in order to nominate individuals for election to the board of directors or to propose matters that can be acted upon at a stockholders’ meeting, which may discourage or deter a potential acquiror from conducting a solicitation of proxies to elect the acquiror’s own slate of directors or otherwise attempting to obtain control of our Company; and
•our board of directors is authorized to issue shares of preferred stock and to determine the terms of those shares, including preferences and voting rights, without stockholder approval, which could be used to significantly dilute the ownership of a hostile acquiror.
Moreover, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law ("DGCL"), which prohibits a person who owns in excess of 15% of our outstanding voting stock from merging or combining with us for a period of three years after the date of the transaction in which the person acquired in excess of 15% of our outstanding voting stock, unless the merger or combination is approved in a prescribed manner.
Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware will be the exclusive forum for substantially all disputes between us and our stockholders, which could limit our stockholders' ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees.
Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty or other wrongdoing by any of our directors, officers, employees or agents to us or our stockholders, (iii) any action asserting a claim arising pursuant to any provision of the DGCL or our amended and restated certificate of incorporation or amended and restated bylaws or (iv) any action asserting a claim governed by the internal affairs doctrine. We believe this provision benefits us by providing increased consistency in the application of Delaware law by chancellors particularly experienced in resolving corporate disputes, efficient administration of cases on a more expedited schedule relative to other forums and protection against the burdens of multi-forum litigation. However, this provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers or other employees, which may discourage such lawsuits against us and our directors, officers and other employees. Alternatively, if a court were to find the choice of forum provision contained in our amended and restated certificate of incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions.
Because we do not anticipate paying any cash dividends on our capital stock in the foreseeable future, capital appreciation, if any, will be your sole source of gain.
We have never declared or paid cash dividends on our capital stock. We currently intend to retain all of our future earnings, if any, to finance the growth and development of our business. In addition, the agreement governing our former credit facility precluded, and any future debt agreements may preclude, us from paying cash dividends. As a result, capital appreciation, if any, of our common stock will be your sole source of gain for the foreseeable future.
General Risk Factors
Changes in U.S. and foreign tax laws could have a material adverse effect on our business, cash flow, results of operations and financial condition.
We are subject to taxation in several countries, and changes in tax laws or challenges to our tax positions could adversely affect our business, results of operations and financial condition. As such, we are subject to tax laws, regulations, and policies of the U.S. federal, state, and local governments and of comparable taxing authorities in foreign jurisdictions. Changes in tax laws in one or more jurisdictions, as well as other factors, could cause us to experience fluctuations in our tax obligations and effective tax rates in the future and otherwise adversely affect our tax positions and/or our tax liabilities. We are unable to predict which, if any, U.S. tax reform proposals will be
72
enacted into law, and what effects any enacted legislation might have on our tax liabilities. On July 4, 2025, the enactment of the One Big Beautiful Bill Act ("OBBBA") into law, marked a significant legislative development, resulting in substantial modifications to the U.S. tax code. The OBBBA influences multiple facets of taxation, including, but not limited to, bonus depreciation, the current-year expensing of research and development costs, and international tax regulations. The impacts to our future financial results from the OBBBA are uncertain. In addition, the current U.S. presidential administration has indicated that the United States may impose retaliatory measures with respect to jurisdictions that have, or are likely to, put in place tax rules that are extraterritorial or disproportionately affect U.S. companies. The likelihood of these changes being enacted or implemented is unclear. We are currently unable to predict what other changes will occur and, if so, the ultimate impact on our business. To the extent that such changes have a negative impact on us or our consumers, including as a result of related uncertainty, these changes may materially and adversely impact our business, financial condition, results of operations and cash flow. There can be no assurance that our effective tax rates, tax payments or tax credits will not be adversely affected by changes in tax laws in various jurisdictions.
Our disclosure controls and procedures may not prevent or detect all errors or acts of fraud.
We have designed our disclosure controls and procedures to provide reasonable assurance that information we must disclose in reports we file or submit under the Exchange Act is accumulated and communicated to management, and recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. We believe that any disclosure controls and procedures, no matter how well-conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met.
These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by an unauthorized override of the controls. Accordingly, because of the inherent limitations in our control system, misstatements due to error or fraud may occur and not be detected.
Securities analysts may not publish favorable research or reports about our business or may publish no information at all, which could cause our stock price or trading volume to decline.
The trading market for our common stock relies in part on the research and reports that securities or industry analysts publish about us or our business. We do not control these analysts. If any of the analysts who cover us provide inaccurate or unfavorable research or issue an adverse opinion regarding our stock price, our stock price could decline. If one or more of the analysts covering our business downgrade our stock or change their opinion of our stock, our stock price would likely decline. In addition, if one or more of these analysts cease coverage of our company or fail to regularly publish reports on us, we could lose visibility in the financial markets, which could cause our share price or trading volume to decline.

Item 1C. Cybersecurity.
Cybersecurity Risk Management and Strategy
73
Our information security program is designed based on the National Institute of Standards and Technology (“NIST”) Cybersecurity v2.0 framework. This does not imply that we meet any particular technical standards, specifications, or requirements, only that we use the NIST framework as a guide in designing and implementing our information security program.
As part of our enterprise risk management process, we assess the various cybersecurity risks that may impact our business and implement plans and initiatives that are intended to mitigate those risks.
Cybersecurity Governance
Our information security program is principally managed by our information security team, which is led by our Senior Director, Information Services and Security . Our Senior Director of Information Services and Security reports to our Vice President of Information Services, who has extensive experience with information technology governance, data management, and systems management, including managing information security and data privacy law compliance at large multinational companies. Our information security team includes professionals with deep professional experience and cybersecurity expertise, including our Senior Director of Information Services and Security. Such expertise includes applicable security and technology degrees and certifications held by information security team members, including degrees in computer science, cybersecurity, and systems engineering and management and security certifications such as COMP TIA Security+, COMP TIA Data+, and GIAC Security Essentials. We also augment our internal cybersecurity expertise by engaging security service organizations.
Our information security team takes steps to stay informed about and monitor efforts to prevent, detect, mitigate, and remediate cybersecurity risks and incidents through a variety of means, including briefings from internal security personnel; threat intelligence and other information obtained from governmental, public or private sources, including external consultants engaged by us; and alerts and reports produced by security tools deployed in the IT environment.

Item 2. Properties.
Our principal offices are located in Golden Valley, Minnesota, where we lease approximately 116,000 square feet of office space. We also lease warehouse space adjacent to our principal office. We lease these spaces under non-cancelable operating lease agreements that expire May 31, 2035, with options to renew for two additional periods of five years each. We intend to add new facilities as we grow, and we believe that suitable additional or substitute space will be available as needed to accommodate any such expansion of our operations.
Item 3. Legal Proceedings.
From time to time we may be involved in claims and proceedings arising in the ordinary course of our business. The outcome of any such claims or proceedings, regardless of the merits, is inherently uncertain.
The information contained in “Note 12 — Commitments and Contingencies” in the Notes to the Consolidated Financial Statements is incorporated by reference into this Item 3.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations.
The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our financial statements and the related notes to those statements included elsewhere in this Annual Report on Form 10-K. In addition to historical financial information, the following discussion and analysis contains forward-looking statements that involve risks, uncertainties, and assumptions. Some of the numbers included herein have been rounded for the convenience of presentation. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of many factors, including those discussed under Part I. "Item 1A. Risk Factors’’ and elsewhere in this Annual Report on Form 10-K.
Overview
We are a medical technology company focused on the development and commercialization of innovative, minimally invasive solutions for patients with obstructive sleep apnea ("OSA"). Our proprietary Inspire system is the only FDA, European Union ("EU") Medical Devices Regulation ("MDR"), and Japan Pharmaceuticals and Medical Devices Agency-approved neurostimulation technology of its kind that provides a safe and effective treatment for patients with moderate to severe OSA. We have developed a novel, closed-loop solution that continuously monitors a patient’s breathing and delivers mild hypoglossal nerve stimulation to maintain an open airway. Inspire therapy is indicated for patients with moderate to severe OSA who do not have significant central sleep apnea and do not have a complete concentric collapse of the airway at the soft palate level.
We sell our Inspire system to hospitals and ambulatory surgery centers ("ASCs") in the U.S. and in select countries in Europe and Japan through a direct sales organization and we sell our Inspire system in Singapore, Hong Kong, and Thailand through distributors. Our direct sales force engages in sales efforts and promotional activities primarily focused on ENT physicians and sleep centers. In addition, we highlight our compelling clinical data and value proposition to increase awareness and adoption amongst referring physicians. We build upon this top-down approach with strong direct-to-consumer marketing initiatives to create awareness of the benefits of our Inspire system and drive interest through patient empowerment. We believe this outreach helps to educate thousands of patients on our Inspire therapy.
Although our sales and marketing efforts are directed at patients and physicians because they are the primary users of our technology, we consider the hospitals and ASCs where the procedure is performed to be our customers, as they are the purchasing agents of our Inspire system. Our customers are reimbursed according to the coding and correlated payment by various third-party payors, such as commercial payors and government healthcare programs. Our Inspire system is currently covered on a per-patient basis for patients insured by commercial payors, under Local Coverage Determinations for patients insured by Medicare and Medicare Advantage, and under U.S. government contract for patients who are treated by the Veterans Health Administration. As of February 13, 2026, we have secured positive coverage policies with many U.S. commercial payors, including all large national commercial insurers, covering more than 300 million lives in the U.S. In addition, all seven Medicare Administrative Contractors provide coverage of Inspire therapy when certain coverage criteria are met.
Third-party payors require physicians and hospitals to identify the service for which they are seeking reimbursement by using Current Procedural Terminology (“CPT") codes, which are created and maintained by the American Medical Association. Our various generations of Inspire therapy have been billed under different codes and reimbursement approaches throughout our history. For example, the procedures performed to implant our Inspire IV device are described for billing purposes using Category I CPT code 64582. And for 2025, the procedures performed to implant our Inspire V device were described for billing purposes using Category I CPT code 64568. There are also other relevant CPT codes for revisions, explants and DISE.
In November 2025, the final 2026 Medicare reimbursement payments were announced. There has been, and still is currently, confusion on the appropriate reimbursement and coding for our products from CMS and Medicare Administrative Contractors ("MACs"), as well as other payors and stakeholders in the overall reimbursement and coding process. Most recently, we received clarification regarding the coding that should be used for the Inspire V procedure. Currently, healthcare centers and physicians should bill the most recent healthcare policies, be it a Medicare Administrative Contractor (MACs) or a commercial payor, and based on this clarification, we believe the
77
code will transition to CPT code 64582 for the Inspire V procedure, including the use of a -52 modifier. To date, our top commercial payers by volume have all adopted the guidance of 64568 for coding and reimbursement of Inspire V. Confusion will remain until there is definitive and public guidance from various stakeholders and we have sufficient claims data that has been submitted and processed across payers. The resulting coding and reimbursement decisions may impact our business, financial condition and results of operations, in particular our future revenues. We continue to work with the relevant stakeholders to get specific and accurate direction for Inspire V coding, including the -52 modifier that we would expect to reduce the professional fee for Inspire V procedures under CPT code 64582 by approximately 10% to 50% of the base rate. In any case, we believe that a significant decrease in the professional fee resulting from use of the –52 modifier will likely influence physicians’ willingness to perform the Inspire V procedure and may limit the number of cases they choose to undertake. Beyond our short-term initiatives intended to minimize the actual reduction applied to the professional fee, as well as to drive consistency across the country, we are seeking a long-term solution, including the creation of a separate CPT code. There can be no guarantee as to the timing or outcome of the CPT code to be applied.
Reimbursement in other countries can often be established through a combination of private (commercial insurance) and public funding sources, or at the hospital level through innovation budgets.
For the year ended December 31, 2025, 95.6% of our revenue was derived in the U.S. and 4.4% was derived outside of the U.S. No single customer accounted for more than 10% of our revenue.
We rely on third-party suppliers to manufacture our Inspire system and its components. Many of these suppliers are currently single source suppliers. Currently, all of our manufacturing is done in the U.S. and most components for our Inspire system are sourced in the U.S. We have experienced supply disruptions in the past.
We typically seek to maintain higher levels of inventory to protect ourselves from supply interruptions, and, as a result, we are subject to the risk of inventory obsolescence and expiration, which could lead to inventory impairment charges. For example, during 2025, we recorded a charge of $2.1 million for excess component parts related to our Inspire IV system.
Since our inception in 2007, we have financed our operations primarily through sales of our Inspire system, private placements of our convertible preferred securities, amounts borrowed under our former credit facility, and equity offerings of our common stock. We have devoted significant resources to research and development activities related to our Inspire system, including clinical and regulatory initiatives to obtain marketing approval, and sales and marketing activities. For the year ended December 31, 2025, we generated revenue of $912.0 million with a gross margin of 85.4% and net income of $145.4 million, compared to revenue of $802.8 million with a gross margin of 84.7% and net income of $53.5 million for the year ended December 31, 2024, and revenue of $624.8 million with a gross margin of 84.5% and a net loss of $21.2 million for the year ended December 31, 2023. Our accumulated deficit as of December 31, 2025 was $146.5 million.
We have invested heavily in product development. Our research and development activities have been centered on driving continuous improvements to our Inspire therapy. We have also made significant investments in clinical studies to demonstrate the safety and efficacy of our Inspire therapy and to support regulatory submissions. We continue to make investments in research and development efforts to develop our future generations of Inspire systems and support our future regulatory submissions for expanded indications and for new markets such as additional European countries and the Asia Pacific region. For example, in August 2024, we received approval from the FDA for our Inspire V neurostimulator ("Inspire V,") which we began to market for sale in the U.S. in May 2025.
Since 2023, glucagon-like peptide 1 ("GLP-1s"), a class of drug indicated for diabetes and obesity, has continued to gain popularity as a weight-loss drug. In late 2024, tirzepatide (marketed as Zepbound), a GLP-1 injection which was FDA approved for weight loss in 2023, was also FDA approved for treatment of OSA in patients with obesity and moderate to severe OSA. If GLP-1s are used to treat OSA in an indication for which Inspire therapy is approved, demand for our Inspire system for patients with that indication could be reduced. OSA is a multifactorial disease with many independent factors including age, gender, weight, and neck circumference. Inspire is designed to address antero-posterior airway collapse, also known as tongue base collapse. In contrast, patients with a higher BMI are subject to a larger neck circumference and present predominantly with lateral-wall collapse.
78
A combination of tongue base collapse and lateral wall collapse is identified as a complete concentric collapse of the upper airway. Inspire is contraindicated for complete concentric collapse. In 2024, Eli Lilly and Company ("Lilly") published results from its SURMOUNT-OSA trial demonstrating a 50.7% reduction in Apnea-Hypopnea Index ("AHI") for patients in the therapy arm of the study using tirzepatide, and that 43% of participants treated with tirzepatide at the highest dose met criteria for disease resolution. In this context, "disease resolution" means achieving an AHI of fewer than 5 events per hour, or an AHI of 5 to 14 events per hour and an Epworth Sleepiness Scale ("ESS") score of ≤10. ESS is a standard questionnaire designed to assess excessive daytime sleepiness. Given a baseline AHI of 50.3, and based on these results, we believe that most patients enrolled in the study will continue to have residual moderate to severe OSA that will require treatment and fall within Inspire’s FDA-approved indication. While weight loss may help reduce a patient’s AHI and other OSA symptoms, numerous other studies have shown that weight loss alone will not resolve OSA for the vast majority of patients. We expect GLP-1s may help patients address their lateral wall collapse, making them a potential candidate for Inspire therapy to the extent they also have tongue base collapse. Based on our ongoing ADHERE patient registry, the average BMI of patients treated with Inspire therapy is 29. The American Academy of Sleep Medicine guidelines recommend weight loss prior to surgery for patients with BMI over 35 and nonsurgical solutions for patients with BMI over 40. In October 2025, we conducted a survey of over 200 sleep physicians to better understand their treatment paradigm for OSA since the introduction of GLP-1s. The survey findings suggest that some physicians will prescribe a GLP-1 to patients prior to considering Inspire therapy. The survey findings also suggest that, with the availability of GLP-1s to treat OSA, the number of patients seeking diagnosis and treatment for OSA is increasing. We believe that some of these patients will see a reduction in their BMI into our indication, and that some of those patients will not have their OSA fully resolved and will require further treatment. This reinforces our belief that the overall number of patients eligible for Inspire therapy will increase in the long-term due to the availability of GLP-1s, although there can be no assurance of such benefit at this time.
Macroeconomic Environment
The global economy continues to experience increased inflationary pressures and market instability. Higher interest rates and capital costs, higher shipping costs and new or increased tariffs, regulatory changes, including changes to government funding of entitlement programs, increased costs of labor, international conflicts and terrorism, and weakening foreign currency exchange rates are creating additional economic challenges. These conditions may cause our customers to decrease or delay orders for our products.
Components of Our Results of Operations
Revenue
We derive primarily all of our revenue from the sale of our Inspire system to hospitals and ASCs in the U.S. and in select countries in Europe and the Asia Pacific region. We recognize revenues from sales of our Inspire system when the customer obtains control of the product, which occurs at a point in time, either upon shipment of the product or receipt of the product, depending on shipment terms.
Our revenue has fluctuated, and may continue to fluctuate, from quarter to quarter due to a variety of factors. For example, we have historically experienced seasonality in our first and fourth quarters. We have also previously experienced adverse impacts on our revenue due to the prior delay in obtaining EU MDR approval of our silicone-based leads and foreign currency exchange rates. In addition, we believe our revenue growth has been adversely impacted by lack of ENT surgeon capacity. If such impacts continue, our revenue growth may be further adversely impacted.
Our business has grown rapidly in recent years, resulting in substantially increased revenues, and we expect that our business will continue to grow. However, our revenue growth rate has generally decelerated in recent periods, and it may continue to do so as a result of the difficulty of maintaining growth rates as our revenues increase to higher levels.
79
Cost of Goods Sold and Gross Margin
Cost of goods sold consists primarily of acquisition costs for the components of the Inspire system, overhead costs, scrap, and inventory obsolescence, warranty replacement costs, as well as distribution-related expenses such as logistics and shipping costs, net of shipping costs charged to customers. The overhead costs include the cost of material procurement, depreciation expense for manufacturing equipment, amortization of internal-use software, and operations and quality supervision and management personnel, including employee compensation, stock-based compensation, supplies, and travel. We expect cost of goods sold to increase or decrease in absolute dollars primarily as, and to the extent, our revenue grows or declines, respectively.
We calculate gross margin as gross profit divided by revenue. Our gross margin has been and we expect it will continue to be affected by a variety of factors, including manufacturing costs, the average selling price of our Inspire system, the implementation of cost-reduction strategies, inventory obsolescence costs, which generally occur when new generations of our Inspire system are introduced, and to a lesser extent the sales mix between the U.S. and countries outside of the U.S., as our average selling price in the U.S. tends to be higher than in other countries. Our gross margin may increase slightly to the extent our production volumes increase and we receive discounts on the costs charged by our contract manufacturers, thereby reducing our per unit costs, and when we implement price increases on our products, thereby increasing our revenue. On the other hand, our gross margin may decrease slightly to the extent our yields decrease, or materials and labor prices increase due to supply chain issues and inflation, thereby increasing our per unit costs. However, our gross margin may also fluctuate from quarter to quarter due to seasonality and foreign currency exchange rates.
Research and Development Expenses
Research and development ("R&D") expenses consist primarily of product development, engineering, clinical studies to develop and support our products, regulatory expenses, quality assurance, testing, consulting services, prelaunch inventory, and other costs associated with the next generation versions of the Inspire system and SleepSync™, a cloud-based patient management system. These expenses include employee compensation, including stock-based compensation, supplies, materials, consulting, and travel expenses related to research and development programs. Additionally, these expenses include clinical study management, payments to clinical investigators, data management and travel expenses for our various clinical studies.
We expense prelaunch inventory as R&D expense in the period incurred unless objective and persuasive evidence exists that regulatory approval and subsequent commercialization of a product candidate is probable, and we also expect future economic benefit from the sales of the product candidate to be realized.
We expect R&D expenses to increase in the future as we invest in our product pipeline, including future versions of our Inspire system and SleepSync™ and continue to expand our clinical studies to further expand positive coverage policies from private commercial payors in the U.S. and enter into new markets including additional European countries and the Asia Pacific region. We expect R&D expenses as a percentage of revenue to vary over time depending on the level and timing of initiating new product development efforts and new clinical development activities.
Selling, General and Administrative Expenses
Selling, general and administrative ("SG&A") expenses consist primarily of compensation for personnel, including base salaries, stock-based compensation expense and commissions related to our sales organization, finance, information technology, human resources, and legal functions, as well as spending related to marketing, sales operations, and training and reimbursement personnel. Other SG&A expenses include training physicians, travel expenses, advertising, direct-to-consumer promotional programs, conferences, trade shows and consulting services, professional services fees, audit fees, insurance costs and general corporate expenses, including facilities-related expenses.
We expect SG&A expenses to continue to increase as we expand our commercial infrastructure to both drive and support our planned growth in revenue and as we increase our headcount and expand administrative personnel to support our growth and operations as a public company including finance, legal, and human resources personnel
80
and information technology services. Additionally, we anticipate an increase in our stock-based compensation expense with grants of restricted stock units, performance stock units, and shares of our common stock purchased pursuant to our employee stock purchase plan.
Other Income, Net
Other income, net consists primarily of interest and dividend income, minimal interest expense, the impacts of foreign currency transactions and remeasurements, gains and losses on investments, and an impairment charge related to a strategic investment.

Revenue
Revenue increased $109.2 million, or 13.6%, to $912.0 million for the year ended December 31, 2025, compared to the year ended December 31, 2024. The increase was attributable to a $101.0 million increase in sales of our Inspire system in the U.S and an increase of $8.1 million outside of the U.S. Overall revenue growth was primarily due to increased market penetration, and, we believe, increased physician and patient awareness of our Inspire system, partially offset by ENT surgeon capacity constraints and some U.S. patients and physicians delaying Inspire therapy until Inspire V is available at their location or while they trial GLP-1 medications.

81
Revenue generated in the U.S. was $872.1 million for the year ended December 31, 2025, an increase of $101.0 million, or 13.1%, over the year ended December 31, 2024. Revenue growth in the U.S. was primarily due to increased market penetration, and, we believe, increased physician and patient awareness of our Inspire system, partially offset by ENT surgeon capacity constraints and some patients and physicians delaying Inspire therapy until Inspire V is available at their location or while they trial GLP-1 medications.
Revenue generated outside of the U.S. was $39.9 million in the year ended December 31, 2025, an increase of $8.1 million, or 25.6%, over the year ended December 31, 2024. Revenue growth outside the U.S. was primarily due to increased market penetration, and, we believe, increased physician and patient awareness of our Inspire system.
Cost of Goods Sold and Gross Margin
Cost of goods sold increased $10.2 million, or 8.3%, to $133.2 million for the year ended December 31, 2025 compared to $123.0 million for the year ended December 31, 2024. The increase was primarily due to product costs associated with the higher sales volume of our Inspire system, and to a lesser extent, the $2.1 million charge associated with excess components related to Inspire IV.
Gross margin was 85.4% for the year ended December 31, 2025 compared to 84.7% for the year ended December 31, 2024. This increase was primarily due to increased sales volume as well as increased sales mix of the Inspire V system, which is less expensive to manufacture and therefore has a higher gross margin than the Inspire IV system, partially offset by the excess inventory component charge discussed above.
Research and Development Expenses
Research and development expenses decreased $11.0 million, or 9.6%, to $103.2 million for the year ended December 31, 2025 compared to $114.1 million for the year ended December 31, 2024. This change was primarily due to a decrease of $12.6 million in ongoing research and development costs, primarily with respect to our next generation versions of the Inspire neurostimulator, our SleepSync™ programmer, and our SleepSync™ platform, and an increase in costs allocated to cost of good sold and inventory of $12.7 million, partially offset by an increase of $14.0 million in compensation and employee-related expenses, mainly as a result of increased headcount and stock-based compensation expense, and an increase of $0.3 million in regulatory submissions and clinical studies expenses and quality compliance fees.
Selling, General and Administrative Expenses
SG&A expenses increased $95.0 million, or 17.9%, to $624.6 million for the year ended December 31, 2025 compared to $529.6 million for the year ended December 31, 2024. The primary driver of this change was an increase of $51.1 million in compensation, including salaries, commissions, stock-based compensation, and other employee-related expenses, mainly as a result of increased headcount. In addition, marketing costs increased $33.0 million, mainly for advertising, and general corporate costs increased $7.0 million, primarily due to legal fees, depreciation expense, computer equipment and software expense, and consulting fees. Also contributing to the increase were travel expenses, which increased by $3.9 million.
Other Income, Net
Other income, net decreased by $7.6 million, or 34.1%, to $14.7 million of income for the year ended December 31, 2025 compared to $22.4 million of income for the year ended December 31, 2024. This change was primarily due to an decrease of $5.7 million in interest and dividend income due to lower cash, cash equivalents, and investment balances, an impairment charge of $4.0 million on one of our strategic investments, and an increase of $0.1 million in interest expense, partially offset by an increase of $2.2 million in foreign currency translation and remeasurement gains due to exchange rates.
82
Income Taxes
We recorded a total income tax benefit of $79.7 million for the year ended December 31, 2025 and $4.9 million of expense for the year ended December 31, 2024. The provision for income taxes for fiscal 2025 includes a deferred tax benefit of $88.8 million related to the release of the valuation allowance against our net deferred tax assets, partially offset by current income tax expense of $9.1 million, which reflects federal and state income tax liabilities that are not fully offset by NOLs and credits due to limitations on net operating loss carryforwards and credits under the Internal Revenue Code of 1986, as amended. We expect that we will record income tax expense in 2026 and beyond as we expect to continue to generate additional taxable income for the foreseeable future.
Year Ended December 31, 2024 Compared to Year Ended December 31, 2023
For a discussion of our results of operations for the year ended December 31, 2024, including a year-to-year comparison between 2024 and 2023, refer to Part II, Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Annual Report on Form 10-K for the year ended December 31, 2024.
Liquidity and Capital Resources
We believe our balance sheet and liquidity as of February 13, 2026 provides us with flexibility, and that our cash, cash equivalents, and investments will satisfy our operating needs and capital expenditures for at least the next 12 months.
Our liquidity and capital structure are evaluated regularly within the context of our annual operating and strategic planning processes. We consider the liquidity necessary to fund our operations, which includes working capital needs, investments in research and development, property, plant, and equipment, and other operating costs. Our sources of capital include sales of our Inspire system and registered offerings of our common stock.
As of December 31, 2025, we had cash, cash equivalents and available-for-sale debt securities of $404.6 million, a decrease of $111.9 million from $516.5 million as of December 31, 2024. Working capital totaled $487.6 million as of December 31, 2025, a decrease of $54.7 million from December 31, 2024. We define working capital as current assets less current liabilities. The decrease in working capital was primarily due to the following factors:
•a decrease of $137.3 million in cash and cash equivalents and short-term available for sale investments primarily due to $175.0 million of share repurchases made under our share repurchase programs, as well as inventory purchases and the payment of taxes on net share settlements of equity awards, partially offset by proceeds from sales of the Inspire system, proceeds from the exercise of stock options, interest and dividend income, and the increase in long-term available for sale investments;
•an increase of $9.7 million in accrued expenses which increased primarily due to compensation and personnel-related costs; and
•a decrease of $1.7 million in prepaid expense and other current assets which increased primarily due to increases in miscellaneous receivables and interest income receivable.
The decrease in working capital was offset by the following factors:
•an increase of $65.2 million in inventory balances, as we increased inventory levels to support higher sales and the launch of Inspire V;
•an increase of $26.6 million in accounts receivable due to higher sales which occurred late in the fourth quarter of 2025; and
•a decrease of $2.1 million in accounts payable.
The primary objective of our investment activities is to preserve our capital for the purpose of funding operations while at the same time maximizing the income we receive from our investments without significantly increasing
83
risk or decreasing availability. To achieve these objectives, our investment policy allows us to maintain a portfolio of certain types of debt securities issued by the U.S. government and its agencies, corporations with investment-grade credit ratings, or commercial paper and money market funds issued by the highest quality financial and non-financial companies. At December 31, 2025, we had $159.8 million in U.S. Treasury debt securities, $116.7 in corporate debt securities, $64.4 million in money market funds, and $23.3 million in commercial paper and asset-asset-backed securities. See Note 2 to our Notes to Consolidated Financial Statements included elsewhere in this Form 10-K for additional information on our investments.
In 2025, our SG&A expenditures increased significantly over the prior year levels, and we anticipate further increases during 2026. Our SG&A expenditures, primarily for increasing headcount and advertising, may exceed any associated increases in revenues, and therefore would reduce our cash flow from operations. We also anticipate R&D expenses will increase during 2026, primarily related to the ongoing development of the SleepSync™ platform and next generation products.
We spent $38.5 million on purchases of property and equipment in 2025, mainly on manufacturing equipment and tooling for Inspire V, development of our SleepSync™ platform, and computer hardware and software. We anticipate further capital expenditures in 2026, primarily for additional manufacturing equipment and our SleepSync™ platform, computer hardware and software, and leasehold improvements on our corporate office buildings.
We believe that our existing cash and cash equivalents and available for sale investments, which totaled $404.6 million as of December 31, 2025, together with cash flows from operations, will provide sufficient liquidity to meet our cash needs and fund our operations and planned capital expenditures for at least the next 12 months. There can be no assurance, however, that our business will continue to generate cash flows at the same levels achieved in prior periods.
Beyond the next 12 months, our cash requirements will depend extensively on the extent of market acceptance of our Inspire system and the demand for our therapy. Our long-term cash requirements also will be significantly impacted by the level of our investment in commercialization, entry and expansion into new markets, whether we make strategic acquisitions, whether we repurchase more shares of our common stock, and competition. We cannot accurately predict our long-term cash requirements at this time. An extended period of global supply chain and economic disruption could materially affect our business, results of operations, access to sources of liquidity, and financial condition. We may seek additional sources of liquidity and capital resources through equity or debt financings, such as additional securities offerings or through borrowings under a new credit facility. There can be no assurance that such transactions will be available to us on favorable terms, if at all.

Operating Activities
Net cash provided by operating activities was $117.0 million for 2025 and consisted of net income of $145.4 million, non-cash charges of $58.9 million, and a decrease in net operating assets of $87.4 million. The non-cash charges consisted primarily of stock-based compensation, which increased mainly as a result of the accelerated recognition of stock-based compensation expense for employees who are retirement eligible in accordance with implementation of changes to the treatment of equity awards under the Inspire Medical Systems, Inc. 2018 Incentive Award Plan upon the holder's death, disability, or retirement, and granting more equity awards to a greater number of employees as compared to the same prior-year period. The remainder of the non-cash charges included the recognition of a deferred tax benefit, depreciation and amortization expense which increased with additional purchases of property and equipment, an impairment of a strategic investment, accretion of investment discount on our available-for-sale investments, a change in the provision for estimated credit losses, and other, net. Operating assets include inventories, which increased as we continue to build inventory levels to support higher sales and the launch of Inspire V, and accounts receivable, which increased primarily due to higher sales which occurred during September 2025. Operating assets also include prepaid expenses and other current assets which increased slightly. Operating liabilities include accounts payable, which increased generally due to the timing of vendor invoice payments, and accrued expenses, which increased slightly.
Net cash provided by operating activities was $130.2 million for 2024 and consisted of net income of $53.5 million, non-cash charges of $114.4 million, and a decrease in net operating assets of $37.7 million. The non-cash charges consisted primarily of stock-based compensation, which increased mainly as a result of granting more equity awards to a greater number of employees as compared to the same prior year period. The remainder of the non-cash charges included accretion of investment discount due to higher investment balances, depreciation and amortization expense which increased with additional purchases of property and equipment, the benefit for estimated credit losses related primarily to accounts receivable with two healthcare systems, and other non-cash expenses. Operating assets include inventories, which increased as supply chain constraints continued to ease and inventory on hand increased to support higher sales and the launch of Inspire V neurostimulator, and accounts receivable, which increased due to the higher sales volume we typically experience late in the fourth quarter. Operating assets also include prepaid expenses and other current assets, which increased primarily due to miscellaneous receivables and interest income receivable on our higher investment balances. Operating liabilities include accrued expenses which increased primarily due to compensation and personnel-related costs, and accounts payable.
85
Investing Activities
Net cash provided by investing activities for 2025 was $21.4 million and consisted primarily of proceeds from sales or maturities of investments of $310.4 million, partially offset by the purchase of investments of $240.3 million, the purchase of strategic investments of $10.1 million and purchases of property and equipment of $38.5 million, mainly on manufacturing equipment and tooling for Inspire V, development of our SleepSync™ platform, and computer hardware and software.
Net cash used in investing activities for 2024 was $113.1 million and consisted primarily of the purchase of investments of $418.4 million, partially offset by $344.6 million of proceeds from sales or maturities of investments. Investing activities also included purchases of property and equipment of $39.1 million, mainly for testing systems and manufacturing equipment for our next generation Inspire system, our SleepSync™ platform, computer hardware and software, and leasehold improvements. We also purchased strategic investments of $0.3 million.
Financing Activities
Net cash used in financing activities was $183.4 million for 2025 and consisted primarily of share repurchases of $175.0 million under our share repurchase authorizations and the payment of $23.0 million of taxes paid on net share settlement of equity awards, partially offset by proceeds from the exercise of stock options of $9.6 million and proceeds from the issuance of common stock from our Employee Stock Purchase Plan ("ESPP") of $5.0 million.
Net cash used in financing activities was $52.4 million for 2024 and consisted primarily of a $75.0 million payment for our ASR agreement and $5.2 million of taxes paid on net share settlement of equity awards, partially offset by proceeds from the exercise of stock options of $22.2 million and proceeds from the issuance of common stock from our ESPP of $5.6 million.
Critical Accounting Estimates
The preparation of the financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the amounts reported in the audited financial statements and accompanying notes included elsewhere in this Annual Report on Form 10-K. We believe that such estimates have been based on reasonable and supportable assumptions and the resulting estimates are reasonable for use in the preparation of the audited financial statements. Actual results could differ from these estimates.
The following areas require management estimates, assumptions, and judgments:
Inventories
Inventories are valued at the lower of cost or net realizable value, computed on a first-in, first out basis. We estimate the recoverability of our inventory by reference to internal estimates of future demands, introduction of new products, and product life cycles, including expiration of inventory prior to sale. We regularly review inventory quantities on-hand for excess and obsolete inventory and, when circumstances indicate, incur charges to write down inventories to their net realizable value. The determination of a reserve for excess and obsolete inventory involves management exercising judgment to determine the required reserve, considering future demand, product life cycles, introduction of new products, and current market conditions. Although we make every effort to ensure the accuracy of our forecasts of future product demand, any significant unanticipated changes in demand could have a significant impact on the carrying value of our inventories and reported operating results. Likewise, the timing of FDA approval of a next generation product, if granted, and the associated commercial launch, could have a significant impact on the carrying value of the inventory of our previous generation product, and therefore our reported operating results. The net inventory balance was $145.3 million and $80.1 million as of December 31, 2025 and 2024, respectively. The reserve for excess and obsolete inventory was $1.3 million and $1.0 million as of December 31, 2025 and 2024, respectively.

Stock-Based Compensation
We maintain an equity incentive plan to provide long-term incentives for eligible employees, consultants, and members of the board of directors. The plan allows for the issuance of performance stock units ("PSUs") which we grant to officers and key employees. The number of PSUs that will ultimately be earned is based on our performance relative to pre-established goals for the three-year fiscal year periods from the date of grant. Management expectations related to the achievement of the performance goals associated with PSU grants is assessed each reporting period, which determines the amount of stock-based compensation expense recorded during the period. The number of shares earned at the end of the three-year periods will vary based on actual performance, from 0% to 200% of the number of PSUs granted. If the performance goals are not met, no shares will be earned. If 200% of the PSUs outstanding as of December 31, 2025 are ultimately earned, the total stock-based compensation expense recognized over the next two-year period ending December 31, 2027 will be $92.9 million. If the performance conditions are not met or not expected to be met, any compensation expense previously recognized associated with the grant will be reversed which will impact our operating results.
Income Taxes
Prior to December 31, 2025, we maintained a full valuation allowance against all of our net deferred tax assets, and as a result we have historically not recorded an income tax benefit in the accompanying consolidated financial statements. This valuation allowance reflected our assessment of whether it is more likely than not that we would generate sufficient taxable income in the future to be able to utilize our deferred tax assets. In determining whether a valuation allowance is warranted, we evaluate factors such as prior earnings history, expected future earnings, carryback and carryforward periods and tax strategies. We consider all positive and negative evidence to estimate if sufficient future taxable income will be generated to realize our deferred tax assets, and we considered cumulative losses in recent years to be a significant type of negative evidence. As of December 31, 2025, we determined that it is more-likely-than-not that a majority of our federal and state deferred tax assets will be realized. As a result, we recorded a release of the valuation allowance associated with these deferred tax assets, which was due in part to achieving three years of cumulative taxable income and projected taxable income that is more than sufficient to realize our federal and state deferred tax assets, and we recorded a deferred income tax benefit in the amount of $88.8 million for the year ended December 31, 2025 (see Note 7 to our Consolidated Financial Statements included elsewhere in this Form 10-K). We utilize financial projections to support our net deferred tax assets, which contain significant assumptions and estimates of future operations. If such assumptions were to differ significantly, it may have a material impact on our ability to realize our net deferred tax assets. Changes in our valuation allowance will result in a change to tax expense.
Recent Accounting Pronouncements
A discussion of recent accounting pronouncements is included in Note 2 to our Consolidated Financial Statements contained elsewhere in this Form 10-K.
Item 7A. Quantitative and Qualitative Disclosures About Market Risk
Interest Rate Risk
The risk associated with fluctuating interest rates is primarily limited to our cash equivalents which are carried at quoted market prices and our short-term investments. We do not currently use or plan to use financial derivatives in our investment portfolio. A hypothetical 1% change in interest rates would have impacted interest and dividend income on our consolidated financial statements by approximately $3.8 million and $3.6 million for the years ended December 31, 2025 and 2024, respectively.
Credit Risk
As of December 31, 2025 and 2024, our cash, cash equivalents, and investments were maintained with financial institutions which we believe have sufficient assets and liquidity to conduct their operations in the ordinary course of business with little or no credit risk to us, however our cash balances were in excess of insured limits. Market

conditions can impact the financial stability of institutions where our cash is held and in the event of a failure, there can be no assurance that we will be able to access uninsured funds in a timely manner or at all.
The primary objective of our investment activities is to preserve our capital for the purpose of funding operations while at the same time maximizing the income we receive from our investments without significantly increasing risk or decreasing availability. To achieve these objectives, our investment policy allows us to maintain a portfolio of certain types of debt securities issued by the U.S. government and its agencies, corporations with investment-grade credit ratings, or commercial paper and money market funds issued by the highest quality financial and non-financial companies. We place restrictions on maturities and concentration by type and issuer. We are exposed to credit risk in the event of a default by the issuers of these securities to the extent recorded on the consolidated balance sheets. See Note 2 of our Consolidated Financial Statements included elsewhere in this Form 10-K for additional information on our cash equivalents and available-for-sale marketable securities.
Our accounts receivable primarily relate to revenue from the sales of our Inspire system to hospitals and ASCs in the U.S. and Europe. We believe that the credit risk in our accounts receivable is mitigated by our credit evaluation process, relatively short collection terms, and the broad diversification of our customer base. We generally do not require collateral, and losses on accounts receivable have historically not been significant. No single customer represented more than 10% of our accounts receivable as of December 31, 2025 or 2024.
Foreign Currency Risk
The majority of our business is currently conducted in U.S. dollars. Any transactions that may be conducted in foreign currencies are not expected to have a material effect on our results of operations, financial position or cash flows.
Inflation Risk
Inflationary factors, such as increases in our cost of goods sold and selling and operating expenses, may adversely affect our operating results. Although we do not believe that inflation has had a material impact on our financial position or results of operations to date, a high rate of inflation in the future may have an adverse effect on our ability to maintain and increase our gross margin and selling and marketing and operating expenses as a percentage of our revenue if the selling prices of our products do not increase as much as or more than these increased costs.

Report of Independent Registered Public Accounting Firm
To the Stockholders and the Board of Directors of Inspire Medical Systems, Inc.
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of Inspire Medical Systems, Inc. (the Company) as of December 31, 2025 and 2024, the related consolidated statements of operations and comprehensive income (loss), stockholders' equity and cash flows for each of the three years in the period ended December 31, 2025, and the related notes (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, in conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated February 13, 2026 expressed an unqualified opinion thereon.
Basis for Opinion
These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the account or disclosures to which it relates.

| Reserves for excess and obsolete inventory | ||||||||
| Description of the Matter | At December 31, 2025, the Company’s net inventory balance was $145.3 million, which included reserves for excess and obsolete inventory of $1.3 million. As explained in Note 2 to the consolidated financial statements, the determination of a reserve for excess and obsolete inventory involves management exercising judgment to determine the required reserve, considering future demand, product life cycles, introduction of new products and current market conditions. Auditing management’s estimate for excess and obsolete inventory reserves involved subjective auditor judgment because of the assumptions and judgments used in determining the excess and obsolete inventory reserves, including future demand, technological or market obsolescence resulting from the introduction of new products, and possible alternative uses for existing products. | |||||||
| How We Addressed the Matter in Our Audit | We obtained an understanding, evaluated the design, and tested the operating effectiveness of controls over the Company's process to determine the amount of the Company’s reserve for excess and obsolete inventory. This included controls over the Company’s review of the significant assumptions and judgments used in determining the reserve estimates. To test the adequacy of the Company's excess and obsolete inventory reserves, we performed audit procedures that included, among others, testing the accuracy and completeness of the underlying data used in the reserve calculations. We performed analytical procedures to evaluate the assumptions and judgments used in determining the inventory reserves, specifically future demand and possible alternative uses. We performed inquiries of Company personnel and inspected regulatory approvals to assess the assumptions used in determining the technological or market obsolescence resulting from the introduction of new products. We also audited management’s calculation of the inventory reserves by testing the mathematical accuracy of the Company’s reserve calculations. | |||||||

1. Organization
Description of Business
2. Summary of Significant Accounting Policies
Basis of Presentation
The consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") and pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC").
Use of Estimates
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts and disclosures reported in the consolidated financial statements. We use significant judgment when making estimates related to the inventory reserves, stock-based awards, and income taxes. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from those estimates.
Cash and Cash Equivalents
We consider all highly liquid securities, readily convertible to cash, that have original maturities of 90 days or less from the date of purchase to be cash equivalents. Cash is carried at cost, which approximates fair value, and cash equivalents, which consist of money market funds, are stated at fair value.
Foreign Currency
Our functional and reporting currency is the U.S. dollar. Our subsidiaries have functional currency in Euro and Yen. The consolidated financial statements are translated to U.S. dollars. Non-monetary assets and liabilities denominated in foreign currencies are translated at rates of exchange in effect at the date of the transaction. Monetary assets and liabilities denominated in foreign currencies are translated using the balance sheet date exchange rate. Sales and expenses denominated in foreign currencies are translated at transaction date exchange rates. Foreign currency transaction gains and losses and the impacts of foreign currency remeasurement are recognized in other expense, net in the consolidated statements of operations and comprehensive income (loss). For the years ended December 31, 2025, 2024, and 2023, we recognized a total of $1.0 million of gains, $0.9 million of losses, and $0.2 million of losses, net, respectively. Any unrealized gains and losses due to translation

adjustments are included in accumulated other comprehensive income within stockholders' equity in the consolidated balance sheets. We had $0.1 million of unrecognized loss and $0.2 of unrecognized gain in our accumulated other comprehensive income balance as of December 31, 2025 and 2024, respectively.

Investments are classified as available-for-sale and are reported at their estimated fair market values which are based on quoted, active or inactive market prices when available. Any unrealized gains and losses due to interest rate fluctuations and other external factors are reported as a separate component of accumulated other comprehensive income within stockholders' equity. We had $0.6 million and $0.4 million of unrecognized gains in our accumulated other comprehensive income balance at December 31, 2025 and 2024, respectively. Any realized gains and losses are calculated on the specific identification method and reported net in other expense, net in the consolidated statements of operations and comprehensive income (loss). We recorded $0 0
As of December 31, 2025, we had no investments with a contractual maturity of greater than three years. Currently, we do not intend to sell the investments, and it is not more likely than not that we will be required to sell the investments before recovery of their amortized cost bases, which may be maturity. We do not consider those investments to be other-than-temporarily impaired as of December 31, 2025. Each reporting period, we evaluate whether declines in fair value below carrying value are due to expected credit losses, as well as our ability and intent to hold the investment until a forecasted recovery occurs. Expected credit losses, not to exceed the amount of the unrealized loss, are recorded as an allowance through other expense in the consolidated statements of operations and comprehensive income (loss). The total allowance for credit losses was $0
Fair Value of Financial Instruments
We measure certain financial assets and liabilities at fair value on a recurring basis, including cash equivalents and investments. Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability. A three-tier fair value hierarchy is established as a basis for considering such assumptions and for inputs used in the valuation methodologies in measuring fair value:
Level 1: Observable inputs, such as quoted prices (unadjusted) for identical assets or liabilities in active markets.
97
Table of Contents
Inspire Medical Systems, Inc.
Notes to Consolidated Financial Statements
(Table amounts in thousands, except share and per share amounts)
Level 2: Inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs (other than quoted prices) that are observable for the asset or liability, either directly or indirectly.
Level 3: Unobservable inputs that are supported by little or no market activities, which would require us to develop our own assumptions.
We classify instruments within Level 1 if quoted prices are available in active markets for identical assets, which include our money market funds and U.S. Treasury debt securities. We classify instruments in Level 2 if the instruments are valued using observable inputs to quoted market prices, benchmark yields, reported trades, broker/dealer quotes or an income approach, such as a discounted cash flow pricing model that calculates values from observable inputs such as quoted interest rates, yield curves and other observable market information. These instruments include our commercial paper, certificates of deposit, corporate debt securities and asset-backed securities. The money market funds and available-for-sale securities are held by two custodians who obtain investment prices from a third-party pricing provider that uses standard inputs (observable in the market) to models which vary by asset class.
The following tables set forth by level within the fair value hierarchy our assets that are measured on a recurring basis and reported at fair value as of December 31, 2025 and 2024. Assets are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

There were no transfers between levels during the years ended December 31, 2025 and 2024.
Concentration of Credit Risk
Financial instruments, which potentially subject us to concentrations of credit risk, consist principally of cash equivalents, investments, and accounts receivable. We maintain the majority of our cash and cash equivalents in accounts with major U.S. and multi-national financial institutions, and our deposits at certain of these institutions exceed insured limits. Market conditions can impact the viability of these institutions. In the event of failure of any of the financial institutions where we maintain our cash and cash equivalents, there can be no assurance that we will be able to access uninsured funds in a timely manner or at all.
Our investment policy limits investments to certain types of debt securities issued by the U.S. government and its agencies, corporations with investment-grade credit ratings, or commercial paper and money market funds issued by the highest quality financial and non-financial companies. We place restrictions on maturities and concentration by type and issuer. We are exposed to credit risk in the event of a default by the issuers of these securities to the extent recorded on the consolidated balance sheets. However, as of December 31, 2025 and 2024, we limited our credit risk associated with cash equivalents by placing investments with banks we believe are highly creditworthy.
We believe that the credit risk in our accounts receivable is mitigated by our credit evaluation process, relatively short collection terms, and dispersion of our customer base. We generally do not require collateral, and losses on accounts receivable have historically not been significant.
Accounts Receivable and Allowance for Expected Credit Losses
Trade accounts receivable are recorded at the invoiced amount and do not bear interest. Customer credit terms are established prior to shipment with the general standard being net 30 days. Collateral or any other security to support payment of these receivables generally is not required.
Each reporting period, we estimate the credit loss related to accounts receivable based on a migration analysis of accounts grouped by individual receivables delinquency status and apply our historic loss rate adjusted for management's assumption of future market conditions. Any change in the allowance from new receivables acquired or changes due to credit deterioration on previously existing receivables is recorded in selling, general and administrative expenses. Write-offs of receivables considered uncollectible are deducted from the allowance. Specific accounts receivable are written off once a determination is made that the amount is uncollectible. The write-

off is recorded in the period in which the account receivable is deemed uncollectible. Recoveries are recognized when received and as a direct credit to earnings or as a reduction to the allowance for credit losses (which would indirectly reduce the loss by decreasing bad debt expense).
The following table presents the changes in the allowance for credit losses related to accounts receivable:

Revenue Recognition
We derive our revenue from sales of our products in the U.S. and internationally. Customers are primarily comprised of hospitals and ambulatory surgery centers, with distributors being used in certain international locations where we do not have a direct commercial presence.
Revenues from product sales are recognized when the customer obtains control of the product, which occurs at a point in time, either upon shipment of the product or receipt of the product, depending on shipment terms. Our standard shipping terms are free on board shipping point, unless the customer requests that control and title to the inventory transfer upon delivery. In those cases where shipping and handling costs are billed to customers, we classify the amounts billed as a component of cost of goods sold.
Revenue is measured as the amount of consideration we expect to receive, adjusted for any applicable estimates of variable consideration and other factors affecting the transaction price, which is based on the invoiced price, in exchange for transferring products. All revenue is recognized when we satisfy our performance obligations under the contract. The majority of our contracts have a single performance obligation and are short term in nature.
Sales taxes and value added taxes in foreign jurisdictions that are collected from customers and remitted to governmental authorities are accounted for on a net basis and therefore are excluded from net sales. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost and are included in cost of goods sold.
Variable consideration related to certain customer sales incentives is estimated based on the amounts expected to be paid based on the agreement with the customer using probability assessments.
We offer customers a limited right of return for our product in case of non-conformity or performance issues. We estimate the amount of our product sales that may be returned by our customers based on historical sales and
102

Notes to Consolidated Financial Statements
(Table amounts in thousands, except share and per share amounts)
returns. As our historical product returns to date have been immaterial, we have not recorded a reduction in revenue related to variable consideration for product returns.
See Note 8 for disaggregated revenue by geographic area.
Cost of Goods Sold
Cost of goods sold consists primarily of acquisition costs for the components of the Inspire system, overhead costs, scrap and inventory obsolescence, warranty replacement costs, costs of supporting our digital platforms, as well as distribution-related expenses such as logistics and shipping costs, net of shipping costs charged to customers. The overhead costs include the cost of material procurement, depreciation expense for manufacturing equipment, and operations and quality supervision and management personnel, including employee compensation, stock-based compensation, supplies, and travel.
Research and Development
Research and development expenses consist primarily of product development, clinical and regulatory affairs, quality assurance, consulting services, and other costs associated with products and technologies in development. These expenses include employee compensation, including stock-based compensation, supplies, materials, prelaunch inventory, consulting, and travel expenses related to research and development programs. Clinical expenses include clinical study design, clinical site reimbursement, data management, travel expenses, and the cost of manufacturing products for clinical studies.
We expense prelaunch inventory as research and development expense in the period incurred unless objective and persuasive evidence exists that regulatory approval and subsequent commercialization of a product candidate is probable and where we also expect the future economic benefit from the sales of the product candidate to be realized.
Stock-Based Compensation
We maintain an equity incentive plan to provide long-term incentives for eligible employees, consultants, and members of the board of directors. The plan allows for the issuance of restricted stock units ("RSUs"), performance stock units ("PSUs"), and non-statutory and incentive stock options to employees, and RSUs, PSUs, and non-statutory stock options to consultants and directors. We also offer an employee stock purchase plan ("ESPP") which allows participating employees to purchase shares of our common stock at a discount through payroll deductions.
We recognize equity-based compensation expense for awards of equity instruments based on the grant date fair value of those awards as expense in the consolidated statements of operations and comprehensive income (loss). We estimate the fair value of stock options using the Black-Scholes option pricing model and the fair value of RSUs and PSUs is equal to the closing price of our common stock on the grant date. The fair value of each purchase under the employee stock purchase plan is estimated at the beginning of the offering period using the Black-Scholes option pricing model.
Stock-based compensation expense is recognized on a straight-line basis over the requisite service period, which is the vesting period or term to become eligible for a qualified retirement for stock options and RSUs, and over the vesting and performance period based on the probability of achieving the performance objectives for PSUs. We account for award forfeitures as they occur.

Leases
Operating leases are included in operating lease right-of-use ("ROU") assets, accrued expenses, and operating lease liabilities – non-current portion in our consolidated balance sheets. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. In determining the present value of lease payments, we use our incremental borrowing rate based on the information available at the lease commencement date as the rate implicit in the lease is not readily determinable. The determination of our incremental borrowing rate requires management judgment based on information available at lease commencement. The operating lease ROU assets also include adjustments for prepayments, accrued lease payments, and exclude lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise such options. Operating lease cost is recognized on a straight-line basis over the expected lease term. Lease agreements that include lease and non-lease components are accounted for as a single lease component. Lease agreements with a noncancelable term of less than 12 months are not recorded on our consolidated balance sheets.
Income Taxes
We account for income taxes using the liability method. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates that will be in effect when the differences are expected to reverse. Valuation allowances against deferred tax assets are established, when necessary, to reduce deferred tax assets to the amounts expected to be realized. Prior to December 31, 2025, as we historically incurred operating losses, we recorded a full valuation allowance against our net deferred tax assets. As of December 31, 2025, we determined that it is more-likely-than-not that our federal and a majority of state deferred tax assets will be realized. As a result, we recorded a release of the valuation allowance associated with these deferred tax assets, which was due in part to achieving three years of cumulative taxable income and projected taxable income that is more than sufficient to realize our federal and a majority of state deferred tax assets. We record a federal, state, and foreign tax provision, which includes a foreign tax reserve relating to uncertain tax positions.
We use financial projections to support our net deferred tax assets, which contain significant assumptions and estimates of future operations. If such assumptions were to differ significantly, it may have a material impact on our ability to realize our deferred tax assets. At the end of each period, we will reassess the ability to realize our deferred tax assets. If it is more likely than not that we would not realize the deferred tax assets, a valuation allowance may need to be established against all or a portion of the deferred tax assets, which will result in a charge to tax expense.
Our policy is to record interest and penalty expense related to uncertain tax positions as other expense in the consolidated statements of operations and comprehensive income (loss).
Comprehensive Income (Loss)
Comprehensive income (loss) consists of net income (loss) and changes in unrealized gains and losses due to interest rate fluctuations and other external factors on investments classified as available-for-sale, and foreign currency translation adjustments. Accumulated other comprehensive income is presented in the accompanying consolidated balance sheets as a component of stockholders' equity.
Income (Loss) Per Share
Basic net income (loss) per share is computed by dividing the net income (loss) by the weighted average number of shares of common stock outstanding during the period. Diluted net income (loss) per share is computed by dividing the net income (loss) by the weighted average number of shares of common stock and dilutive potential shares of common stock outstanding during the period. For the periods presented with a net loss, diluted net loss per share is
104

the same as basic net loss per share as all potentially dilutive shares consisting of outstanding stock options, unvested RSUs and PSUs, and shares issuable under our employee stock purchase plan were antidilutive in those periods.
Purchase Commitments
We had purchase commitments to suppliers for purchases totaling $90.5 million as of December 31, 2025.
Recent Accounting Pronouncements
In November 2024, the FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income-Expense Disaggregation (Subtopic 220-40): Disaggregation of Income Statement Expenses (“ASU 2024-03”). The guidance requires the disclosure of additional information related to certain costs and expenses, including amounts of inventory purchases, employee compensation, and depreciation and amortization included in each income statement line item. ASU 2024-03 also requires disclosure of the total amount of selling expenses and our definition of selling expenses. The ASU is effective for our annual reports beginning in fiscal 2027, and interim period reports beginning in fiscal 2028 either on a prospective or retrospective basis. Early adoption is permitted. We are currently evaluating the impact of adopting ASU 2024-03 on our financial statement disclosures.
In September 2025, the FASB issued ASU 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Topic 350): Targeted Improvements to the Accounting for Internal-Use Software. This ASU modifies the criteria for when software costs may be capitalized by eliminating consideration of software project development stages and by enhancing guidance for the "probable-to-complete" threshold. This ASU is effective for our annual reports beginning in 2028, and interim periods within those annual reporting periods. Early adoption of this ASU is permitted. We are currently evaluating the impact that adoption of this ASU may have on our financial statements and disclosures.
We have reviewed and considered all other recent accounting pronouncements that have not yet been adopted and believe there are none that could potentially have a material impact on our business practices, financial condition, results of operations, or disclosures.
3. Leases
We lease office space for our corporate headquarters under a non-cancelable operating lease. The prior corporate office leases were amended in May 2023 to increase the total space leased to approximately 106,000 square feet and to extend the noncancellable lease term through May 2035. In October 2024, we entered into an amendment on this lease which provides approximately 10,000 square feet of additional space.
We entered into a warehouse and office space lease for our corporate headquarters under a non-cancelable operating lease in August 2023. This space includes approximately 22,000 square feet and a noncancellable lease term through May 2035. In March 2024, we entered into an amendment on this lease which commenced in January 2025 which provides for approximately 18,000 square feet of additional space.
Each lease described above includes options to renew for up to two five years
In addition to base rent in these leases, we also pay our proportionate share of the operating expenses, as defined in the leases. These payments are made monthly and adjusted annually to reflect actual charges incurred for operating expenses, such as common area maintenance, taxes, and insurance.

4. Employee Retirement Plan
We sponsor a defined contribution employee retirement plan covering all of our full-time employees. The plan allows eligible employees to defer a portion of their eligible compensation up to the maximum allowed by IRS Regulations. We make voluntary matching contributions of 50 % of the first 6 % of each participating employee's contribution, up to 3 % of eligible earnings. Our match contributions are made to funds designated by the participant, none of which are based on Inspire common stock, and totaled $5.6 million, $4.7 million, and $3.7 million for the years ended December 31, 2025, 2024, and 2023 respectively.

5. Stockholders' Equity
Share Repurchase Programs
In August 2024, our Board of Directors authorized the repurchase of up to $150.0 million of our outstanding shares of common stock from time to time through open market transactions, privately negotiated transactions, tender offers, or other means (the “2024 share repurchase program”). We are not obligated to repurchase any specific number of shares and the program may be modified, suspended, or discontinued at any time. The share repurchase program was set to expire in August 2026, subject to the earlier termination or extension by the Board, in its sole discretion and without prior notice.
In November 2024, we entered into an accelerated share repurchase agreement (the “ASR Agreement”) with a large financial institution to repurchase common stock as part of the 2024 share repurchase program. Under the ASR Agreement, the financial institution delivered a portion of shares to us at contract inception and delivered the remaining shares at settlement. We made a prepayment of $75.0 million and received an initial delivery of 305,157 shares of common stock. We retired the initial shares delivered and recorded a $75.0 million reduction to additional paid-in capital. We accounted for the variable component of shares to be delivered under the ASR Agreement as a forward contract indexed to our common stock, which met the criteria for equity classification, and therefore, was accounted for as a component of equity.
In January 2025, we were notified of the early termination of the ASR Agreement. Upon final settlement in January 2025, we received an additional 103,886 shares of common stock from the financial institution. The final number of shares received was based on the volume-weighted average price of our common stock during the term of the ASR Agreement, less a discount and subject to adjustment pursuant to the terms of the ASR Agreement. The total shares repurchased under the ASR Agreement was 409,043 shares with the average share price of $190.29 .
During 2025, we purchased an additional 442,649 shares for the remaining $75.0 million under Rule 10b5-1 under the 2024 share repurchase program. As of March 31, 2025, no amount remained available for future repurchases under the 2024 share repurchase program.
In August 2025, our Board of Directors authorized the repurchase of up to $200.0 million of our outstanding shares of common stock from time to time through open market transactions, privately negotiated transactions, tender offers, or other means (the “2025 share repurchase program”). We are not obligated to repurchase any specific number of shares and the program may be modified, suspended, or discontinued at any time. The 2025 share repurchase program will expire in August 2027, subject to the earlier termination or extension by the Board, in its sole discretion and without prior notice. During 2025, we purchased 1,076,225 shares for $100.0 million under Rule 10b5-1 under the 2025 share repurchase program. Our share repurchases in excess of issuances are subject to a 1% excise tax enacted by the Inflation Reduction Act. Any excise tax incurred is recognized as part of the cost basis of the shares acquired in the consolidated statements of equity. As of December 31, 2025, $100.0 million remained available for future repurchases under the 2025 share repurchase program.
6. Stock-Based Compensation
As of December 31, 2025, there were 4,598,570 shares reserved for issuance under the Inspire Medical Systems, Inc. 2018 Incentive Award Plan, of which 1,319,587 shares were available for issuance.
Stock-based compensation expense is recognized on a straight-line basis over the requisite service period, which is the vesting period or term to become eligible for a qualified retirement for stock options and RSUs, and over the vesting and performance period based on the probability of achieving the performance objectives for PSUs, and is reduced by actual forfeitures as they occur. If there are any modifications or cancellations of the underlying unvested securities, we may be required to accelerate, increase, or cancel any remaining unearned stock compensation expense. Future stock-based compensation expense and unearned stock-based compensation will increase to the extent that we grant additional stock-based awards.

(Table amounts in thousands, except share and per share amounts)
During the year ended December 31, 2025, we recorded accelerated stock-based compensation expense of $11.2 million for employees who are retirement eligible in accordance with the implementation of changes to the treatment of equity awards under the Inspire Medical Systems, Inc. 2018 Incentive Award Plan upon the holder's death, disability, or retirement.
Stock Options
Stock options are granted to employees at the exercise price, which is equal to the closing price of our stock on the date of grant. The stock options include a four-year service period and 25 % vest after the first year of service and the remainder vest in equal monthly installments over the next 36 months of service. Unvested options are forfeitable in the event of termination other than for death, disability, or qualifying retirement. Upon death, disability or qualifying retirement, all outstanding and unvested options accelerate and become fully vested. The stock options have a contractual life of ten years .
The fair value per share of options is estimated on the date of grant using the Black-Scholes option pricing model. There were no stock options granted during the year ended December 31, 2025.

| Assumptions: | |||||||||||||||||
| Expected term (years) | |||||||||||||||||
| Expected volatility | |||||||||||||||||
| Risk-free interest rate | |||||||||||||||||
| Expected dividend yield | |||||||||||||||||
Expected Term — Due to our limited amount of historical exercise, forfeiture, and expiration activity, we have opted to use the "simplified method" for estimating the expected term of options, whereby the expected term equals the arithmetic average of the vesting terms and the original contractual term of the option. We will continue to analyze our expected term assumption as more historical data becomes available.
Expected Volatility — During the year ended December 31, 2024, we based expected volatility on the historic volatility of our common stock. Prior to 2024, due to our limited company specific historical and implied volatility data, we incorporated our historical stock trading volatility with those of a group of similar companies that are publicly traded for the calculation of volatility. When selecting this peer group, we generally selected companies with comparable characteristics, including enterprise value, stages of clinical development, risk profiles, position within the industry, and those with historical share price information sufficient to meet the expected life of the stock-based awards.
Risk-Free Interest Rate — The risk-free rate assumption is based on the U.S. government Treasury instruments with maturities similar to the expected term of our stock options.
Expected Dividend Yield — The expected dividend assumption is based on our history of not paying dividends and our expectation that we will not declare dividends for the foreseeable future.

The aggregate intrinsic value of options exercised is the difference between the estimated fair market value of our common stock at the date of exercise and the exercise price for those options. The aggregate intrinsic value of outstanding options is the difference between the closing price as of the date outstanding and the exercise price of the underlying stock options. The total grant date fair value of options vested during the year was $38.9 million, $56.7 million and $45.7 million for the years ended December 31, 2025, 2024, and 2023, respectively. As of December 31, 2025, the amount of unearned stock-based compensation currently estimated to be expensed from now through the year 2028 related to unvested stock options is $26.4 million which we expect to recognize over a weighted average period of 1.5 years.
Restricted Stock Units
RSUs are share awards that entitle the holder to receive freely tradable shares of our common stock upon vesting. The RSUs cannot be transferred and the awards are subject to forfeiture in the event of termination other than for death, disability, or qualifying retirement. Upon death or disability, all outstanding and unvested RSUs accelerate and become fully vested and settled. Upon qualifying retirement, all outstanding and unvested RSUs remain outstanding and settle in accordance with the original vesting and payment terms applicable to such RSUs. The RSUs granted to employees include - or four-year service periods and vest in equal installments on each anniversary of the date of grant. The RSUs granted to the board of directors include - or three-year service periods and vest in equal installments on each anniversary of the date of grant. The fair value of the RSUs is equal to the closing price of our common stock on the grant date.
A summary of RSUs and related information is as follows:

The aggregate intrinsic value of unvested RSUs was based on our closing stock price on the last trading day of the period. The aggregate intrinsic value of vested RSUs was based on our closing stock price on the date of vest. As of December 31, 2025, the amount of unearned stock-based compensation currently estimated to be expensed from now through the year 2028 related to unvested RSUs is $123.5 million which we expect to recognize over a weighted average period of 1.9 years.
Performance Stock Units
We grant PSUs to officers and key employees. The number of PSUs that will ultimately be earned is based on our performance relative to pre-established goals for the respective three-year periods from the year of grant. The expense is recorded on a straight-line basis over the requisite service periods based on an estimate of the number of PSUs expected to vest. Management expectations related to the achievement of the performance goals associated with PSU grants are assessed each reporting period. The number of shares earned at the end of each of the three-year periods will vary based on actual performance, from 0 % to 200 % of the number of PSUs granted. If the performance conditions are not met or not expected to be met, any compensation expense recognized associated with the grant will be reversed. PSUs are subject to forfeiture in the event of termination other than a termination due to death, disability, or qualifying retirement occurring after the first 12 months of the applicable performance period. Upon such a termination due to death or disability, a prorated amount of the target number of PSUs will accelerate and become fully vested. Upon such a qualifying retirement, a prorated amount of the PSUs will be eligible to vest and settle based on the actual performance achievement in accordance with the original vesting and payment terms applicable to such PSUs.

The fair value of the PSUs is equal to the closing price of our common stock on the grant date. The aggregate intrinsic value of unvested PSUs was based on our closing stock price on the last trading day of the period. As of December 31, 2025, there was $26.2 million of unrecognized stock-based compensation expense related to outstanding PSUs that is expected to be recognized over a weighted average period of 1.4 years.
Employee Stock Purchase Plan
Employees may participate in our ESPP provided they meet certain eligibility requirements. The purchase price for our common stock under the terms of the ESPP is defined as 85 % of the lower of the closing market price per share of our common stock on the first or last trading day of a purchase period. We issued 52,015 shares under the ESPP during 2025 and there were 1,332,425 shares available for future issuance under the ESPP as of December 31, 2025.

Deferred income taxes reflect the tax effects of net operating loss carryforwards, tax credit carryforwards, and the net temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes.
As of December 31, 2025, we had utilized all of the gross federal net operating loss carryforwards from prior years. We had net operating loss carryforwards for state income tax purposes of $60.6 million, which will begin to expire in 2026. We also have gross R&D credit carryforwards of $14.7 million as of December 31, 2025 which will expire at various dates beginning in 2034.
Utilization of the R&D credit carryforwards may be subject to an annual limitation due to the ownership change limitations provided by Section 382 and Section 383 of the Code and similar state provisions. During the year ended December 31, 2025, we finalized an updated analysis to determine whether an ownership change had occurred

through December 31, 2024, and if a limitation exists. It was determined that December 11, 2018 was the only date that we experienced an ownership change. The study concluded that none of the $126.5 million of federal net operating losses nor the $1.7 million of federal R&D credits that were accumulated on December 11, 2018 will expire unused solely due to the limitations under Sections 382 and 383 of the Code.
Based on our analysis of all positive and negative evidence available for the year ended December 31, 2025, having demonstrated sustained profitability which is objective and verifiable, and taking into account anticipated future earnings, we concluded it is more likely than not that the majority of our U.S. federal and U.S. states net deferred tax assets will be realizable. Accordingly, we have recognized a non-recurring tax benefit of $88.8 million for the year ended December 31, 2025. As of December 31, 2025, $5.7 million of our valuation allowance remained against certain tax attributes. The valuation allowance decreased by $101.7 during the year ended December 31, 2025.
On July 4, 2025, the enactment of the One Big Beautiful Bill Act ("OBBBA") into law, marked a significant legislative development, resulting in substantial modifications to the U.S. tax code. The OBBBA influences multiple facets of taxation, including, but not limited to, bonus depreciation, the current-year expensing of research and development costs, and international tax regulations. The income taxes reported for the year ended December 31, 2025 incorporates all relevant tax provisions of this new law.
The changes to our gross unrecognized tax benefits were as follows:

We file income tax returns in the applicable jurisdictions. The 2021 to 2024 tax years remain open to examination by the major taxing authorities to which we are subject. We do no t expect a significant change to our unrecognized tax positions over the next 12 months.
Our policy is to record interest related to uncertain tax positions as interest expense and any penalties as other expense in our consolidated statements of operations and comprehensive income (loss). There were no
8. Segment Reporting and Revenue Disaggregation
We operate our business as one
Our CODM uses consolidated net income (loss) as the measure of profit or loss. Our CODM assesses performance for the segment and allocates resources and monitors budget versus actual results using consolidated net income (loss) and operating income (loss). The monitoring of budget versus actual results are used in establishing management's compensation. The measure of segment assets is reported on the balance sheet as total consolidated assets.

9. Income (Loss) Per Share
Basic net income (loss) per share is computed by dividing the net income (loss) by the weighted average number of shares of common stock outstanding during the period. Diluted net income (loss) per share is computed by dividing the net income (loss) by the weighted average number of shares of common stock and dilutive potential shares of common stock outstanding during the period. For the periods presented with a net loss, diluted net loss per share is the same as basic net loss per share as all of the following potentially dilutive shares were antidilutive in those periods.

10. Related Party Transaction
In December 2023, we entered into an agreement with an entity controlled by our CEO (the "Entity"), pursuant to which we agreed to share the costs of a corporate suite at a sports and entertainment venue (the "Venue") (the “Suite”) (the “Cost Sharing Agreement”). In August 2023, the Entity entered into an agreement with the Venue, pursuant to which the Entity acquired certain rights to use the Suite for specified sporting and other events at the Venue through August 2026. Pursuant to this agreement, the Entity agreed to pay $0.2 million per year, with each year beginning September 1 and ending August 31, and the fee increasing by 5 % for each succeeding year. Under the Cost Sharing Agreement, we will reimburse the Entity 50 % of the cost of the Suite in exchange for the right to use the Suite for 50 % of the specified events at the Venue through August 2026. We recognized expense of $0.3 million, $0.2 million, and $0.1 million for the use of the suite in SG&A expense in our consolidated statements of

operations and comprehensive income (loss) for the years ended December 31, 2025, 2024, and 2023, respectively.
11. Commitments and Contingencies
We may from time to time be involved in claims, governmental inquiries or investigations, litigation and other legal proceedings arising in the ordinary course of business, some of which may seek monetary damages, including claims for punitive damages, which may not be covered by insurance. Such matters, even if not meritorious, could result in the expenditure of significant financial and managerial resources. We evaluate all matters and record liabilities for losses from legal proceedings when we determine that it is probable that the outcome will be unfavorable and the amount, or potential range, of loss can be reasonably estimated. An adverse determination in one or more of these pending matters could have an adverse effect on our consolidated financial position, results of operations or cash flows.
On November 6, 2025, the City of Pontiac Reestablished General Employees’ Retirement System, on behalf of itself and other similarly situated investors, filed a putative securities class action in the United States District Court for the District of Minnesota against the Company and certain of its executive officers, captioned City of Pontiac Reestablished General Employees’ Retirement System v. Inspire Medical Systems, Inc., et al., Case No. 0:25‑cv‑04247‑PJS‑ECW (D. Minn.) (the “City of Pontiac Lawsuit”). The complaint alleged violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Rule 10b‑5 promulgated thereunder, based on purportedly materially false and misleading statements made between August 6, 2024, and August 4, 2025, regarding the launch of the Company’s Inspire V neurostimulator. The complaint further alleged that when subsequent disclosures were made concerning issues with the Inspire V launch and the Company announced its third‑quarter fiscal 2025 results, the Company’s stock price declined, purportedly causing investor losses. On December 23, 2025, the plaintiff filed a Notice of Voluntary Dismissal. On December 29, 2025, the case was administratively closed without prejudice.
On December 22, 2025, the Indiana Public Retirement System, on behalf of itself and other similarly situated investors, filed a putative securities class action in the United States District Court for the Southern District of New York against the Company and certain of its executive officers, captioned Indiana Public Retirement System v. Inspire Medical Systems, Inc., et al., Case No. 1:25‑cv‑10620 (S.D.N.Y.) (the “Indiana PRS Lawsuit”). The Indiana PRS Lawsuit arises from the same underlying subject matter as the City of Pontiac Lawsuit. It alleges the same violations of law and is based on the same or similar purportedly materially false and misleading statements made during the same class period, all of which relate to the launch of the Company’s Inspire V neurostimulator. The plaintiffs seek, among other relief, unquantified compensatory damages, together with attorneys’ fees and costs. On January 22, 2026, the Company and the individual defendants moved to transfer the case to the United States District Court for the District of Minnesota. That motion remains pending. The Company and the individual defendants intend to vigorously defend against the action. No accrual for loss has been accrued or recorded in the Company’s financial statements as of, or for the period ended, December 31, 2025 since the Company is unable to determine whether any loss ultimately will occur or to estimate the range of such loss.
On January 17, 2025, we received a civil investigative demand (“CID”) from the Department of Justice U.S. Attorney’s Office for the District of Minnesota pursuant to the False Claims Act in the course of the government’s investigation concerning allegations of false claims, including false claims arising from violations of the Anti-Kickback Statute, submitted to government payors in connection with our implant. The CID requests information relating to the marketing, promotion, and reimbursement practices associated with our products. We are cooperating with the investigation. No assurance can be given as to the timing or outcome of the government’s investigation. No amount of loss has been accrued or recorded in the Company’s financial statements as of, or for the period ended, December 31, 2025 since the Company is unable to determine whether any loss ultimately will occur or to estimate the range of such loss.
On May 30, 2025, Inspire filed a lawsuit against Nyxoah SA and its subsidiary Nyxoah, Inc. (collectively “Nyxoah”) in the United States District Court for the District of Delaware, alleging that Nyxoah's Genio product infringes on

Table of Contents

(Table amounts in thousands, except share and per share amounts)
certain of Inspire's U.S. patents related to neurostimulation therapy for obstructive sleep apnea. Inspire seeks a judgment of patent infringement and relief for such infringement, including monetary damages such as lost profits. Nyxoah has denied infringement and has asserted counterclaims seeking declaratory judgments of invalidity and non‑infringement. On December 18, 2025, Nyxoah filed three (3) petitions with the United States Patent Trial and Appeal Board seeking inter partes review (IPR) of the three patents asserted by Inspire in the lawsuit. Because these matters are in their early stages, we cannot predict the outcome or estimate the range of potential loss.
On September 15, 2025, Nyxoah filed a lawsuit against us in the United States District Court for the District of Delaware alleging that the Inspire IV and Inspire V devices infringe certain of Nyxoah’s patents. The lawsuit is in its early stages. The Company intends to defend the claims in this lawsuit vigorously and believes it has good and substantial defenses to them, but there is no guarantee that the Company will be successful in these efforts. No amount of loss has been accrued or recorded in the Company’s financial statements as of and for the period ended December 31, 2025 since the Company is unable to determine whether any loss ultimately will occur or to estimate the range of such loss.
On December 5, 2025, Nyxoah brought suit against Inspire and its wholly-owned subsidiary, Inspire Medical Systems Europe GmbH in the Unified Patent Court, Munich Division, alleging that the Inspire IV implantable neurostimulator infringes a patent owned by Nyxoah. The lawsuit is in its early stages. The Company intends to defend the claims in this lawsuit vigorously and believes it has good and substantial defenses to them, but there is no guarantee that the Company will be successful in these efforts. No amount of loss has been accrued or recorded in the Company’s financial statements as of and for the period ended December 31, 2025 since the Company is unable to determine whether any loss ultimately will occur or to estimate the range of such loss.

Item 9A. Controls and Procedures.
Evaluation of Disclosure Controls and Procedures
Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2025. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of December 31, 2025, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.
Changes in Internal Control over Financial Reporting
There was no change in the Company’s internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act, that occurred during the quarter ended December 31, 2025 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
Management Report on Internal Control over Financial Reporting
Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Internal control over financial reporting is a process designed by, or under the supervision of, a company’s principal executive and principal financial officers, or persons performing similar functions, and effected by the company’s board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles. It includes those policies and procedures that:
•pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the company;
•provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and
•provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management Report on Internal Control over Financial Reporting.

We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.
Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control Over Financial Reporting

Exhibit 10.24 AMENDMENT TO TRANSITION AND SEPARATION AGREEMENT This Amendment (this "Amendment") is made and entered into as of January 10, 2026 (the “Amendment Effective Date”) by and between Inspire Medical Systems, Inc. (the "Company") and Richard J. Buchholz (the "Executive"). Reference is made to that certain Transition and Separation Agreement, dated August 26, 2025, by and between the Company and the Executive (the "Agreement"). This Amendment is intended to modify the Agreement on a targeted basis only, as set forth below. WHEREAS, the parties desire to amend specific provisions of the Agreement to provide for Executive to serve as the Company’s Interim Chief Financial Officer and be designated as the Company’s interim principal financial officer and interim principal accounting officer through the filing of the Company’s Form 10-K for the fiscal year ended December 31, 2025; and WHEREAS, except as expressly amended herein, the Agreement shall remain in full force and effect. NOW THEREFORE, in consideration of the mutual promises set forth herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties, intending to be legally bound, do hereby agree as follows: AMENDMENTS 1. Defined Terms; References. Capitalized terms used but not defined in this Amendment have the meanings ascribed to them in the Agreement. References to sections herein are to sections of the Agreement unless otherwise indicated. 2. Amendments to Agreement. (a) Section 1 (Separation Date; Transition Period) of the Agreement is hereby amended and restated in its entirety as follows: 1. Separation Date; Transition Period. Executive's employment with the Company shall end effective as of the close of business on February 28, 2026, (the “Separation Date”), unless Executive's employment with the Company is terminated prior to such date pursuant to Section 1 of the Agreement, in which case, such termination date shall be deemed the Separation Date. During the period commencing on the Amendment Effective Date and continuing through the time the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025 (the “2025 10-K”) is filed with the Securities and Exchange Commission (such period, the “Interim CFO Period”), Executive shall serve as the Company’s Interim Chief Financial Officer, reporting to the Company’s Chief Executive Officer and shall perform such duties as are customarily associated with such position or as mutually agreed with the Company’s Chief Executive Officer in light of the transition of his responsibilities, including, for the avoidance of doubt, serving as the Company’s interim principal financial officer and interim principal accounting officer. During the period commencing the day after the Interim CFO Period ends and through the remainder of the Transition Period, Executive shall serve in an advisory capacity to the Company. During the Transition Period (as defined below), Executive shall not be required to report to the
2 Company's offices except when reasonably necessary to fulfill his duties or obligations as required under this Agreement, or for specific, pre-determined meetings or events as may be mutually agreed upon by Executive and the Company. Throughout the Transition Period, Executive will dutifully and diligently perform the below responsibilities, including, but not limited to: (a) work on initiatives and projects that have been or will be assigned by the Company's Chief Executive Officer or his delegate; (b) provide the support required for the completion of the Company's 2025 audited financial statements and the timely filing of the 2025 10-K (including signing the 2025 10-K and providing customary certifications to the 2025 Form 10-K pursuant to Section 302 and 906 of the Sarbanes-Oxley Act of 2002 and any related certifications or signatures); and (c) assist with the transition of his responsibilities, including without limitation, meeting with Company personnel, answering questions from Company personnel, and transferring knowledge to Company personnel. Effective as of 11:59 p.m. Central Time on December 31, 2025, Executive shall and has resigned from his position as Chief Financial Officer of the Company, any and all other officer positions that he may hold with the Company, and any and all officer and director positions that he may hold with any of the Company's subsidiaries, affiliates, and related entities; provided, however, that during the Interim CFO Period, Executive serve as an officer of the Company and shall be designated as the Company’s interim principal financial officer and principal accounting officer. Executive will cooperate with the Company to complete, sign, and submit any and all documentation required by law or practice to effect these resignations and responsibilities. Nothing in this Amendment or the Agreement is intended to modify Executive's status as an at-will employee; the Company retains its right to terminate Executive for any lawful reason, with or without notice, at any time during the Transition Period. If the Company terminates Executive's employment for Cause (as defined in the Employment Agreement (as defined below)) or if Executive voluntarily resigns, in either case, during the Transition Period, Executive will not be eligible to receive the Separation Pay set forth in Section 3 of the Agreement. If the Company terminates Executive's employment for reasons other than Cause during the Transition Period, Executive will entitled to receive the Separation Pay set forth in Section 3 of the Agreement and subject to the conditions therein).

As used herein, “Transition Period” shall mean the period between the Effective Date and the Separation Date.
3 3. No Other Amendments; Confirmation. Except as expressly set forth in Section 2 above, the Agreement is unmodified and remains in full force and effect. The parties hereby ratify and confirm the Agreement, as amended by this Amendment. 4. Effectiveness. This Amendment will be effective as of the date hereof. 5. Governing Law.

(a) If any provision of this Amendment is held to be invalid or unenforceable, such provision shall be enforced to the maximum extent permissible and the remaining provisions shall remain in full force and effect.

4 IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of the date hereof. INSPIRE MEDICAL SYSTEMS INC. By: /s/ Timothy P. Herbert Name: Timothy P. Herbert Title: Chief Executive Officer EXECUTIVE /s/ Richard J. Buchholz Name: Richard J. Buchholz
Exhibit 10.25 EXECUTIVE EMPLOYMENT AGREEMENT This EXECUTIVE EMPLOYMENT AGREEMENT (“Agreement”) is made and entered into as of January 6, 2026 (the “Effective Date”), by and between Inspire Medical Systems, Inc. (“Inspire” or the “Company”), a Delaware corporation, and Matthew J. Osberg (“Executive”). WHEREAS, Executive desires to provide services to the Company on the terms herein provided. NOW, THEREFORE, in consideration of the foregoing premises and the mutual covenants and obligations of this Agreement, the receipt and sufficiency of which are hereby acknowledged, the parties agree as follows: 1. Employment. Subject to all of the terms and conditions of this Agreement, Inspire agrees to employ Executive, and Executive agrees to accept employment with Inspire, as the Company’s Executive Vice President and Chief Financial Officer, reporting to the Company’s Chief Executive Officer. It is understood that Executive and Executive’s employment with Inspire will be subject to the policies and terms (as they may be amended from time to time by Inspire) as adopted by Inspire’s Board of Directors (the “Board”) or its Chief Executive Officer, Inspire’s employee handbook and other policies in effect for salaried employees of Inspire, except as otherwise specifically provided in this Agreement. Executive’s anticipated start date will be January 19, 2026 (the “Start Date”). 2. Duties. The services of Executive shall be exclusive to Inspire, except as otherwise agreed to in writing by Inspire. Executive shall assume primary responsibility for and perform the duties of the Executive’s position and such other duties as may be mutually agreed upon by Executive and the Company’s Chief Executive Officer, shall exert Executive’s energy and full business time to the prosecution of Executive’s duties, and shall promptly and faithfully perform all these duties which pertain to that employment. Executive will perform Executive’s obligations in a competent and professional manner, consistent with the expectations of Inspire’s Board and its Chief Executive Officer. Executive may serve on outside boards of directors or committees of public or private organizations if the outside activities are first disclosed to and approved in writing by Inspire’s Board or its Chief Executive Officer. That approval will not be granted if the outside activities are deemed by the Board or Inspire’s Chief Executive Officer to conflict in any way with the provisions of this Agreement, to impair Executive’s ability to perform Executive’s duties under this Agreement, or to otherwise conflict in any way with business interests of Inspire. Notwithstanding the foregoing, the Executive may participate in the activities set forth on Exhibit A and may without advance approval participate in charitable activities (including, but not limited to, service on the boards of charitable or nonprofit organizations), and engage in personal investment activities, in each case, to the extent that such activities, individually or in the aggregate, do not materially interfere with the performance of the Executive’s duties under this Agreement, create a conflict of interest or violate any provision of this Agreement. 3. Term of Employment. This Agreement is not intended to establish any minimum or maximum period for Executive’s employment. Executive and Inspire have an “at-will” employment relationship, which means that either party has the right to terminate the employment
2 relationship at any time and for any reason, with or without Cause. The reason for and timing of the termination, as set forth in Paragraph 5, will determine the amount of post-termination payments and benefits, if any, as set forth in Paragraph 6. 4. Compensation, Reimbursement and Benefits. As compensation for all of Executive’s services under this Agreement, the Company agrees to provide Executive the following compensation, reimbursements and benefits: a. Sign-on Compensation: In consideration for Executive commencing employment with the Company, Executive shall receive the following: i. Sign-On Bonus. The Company shall pay to Executive a cash bonus in an amount equal to $600,000, less applicable withholdings and deductions (the “Signing Bonus”). The Signing Bous shall be paid in two equal parts: (A) half on the first regular payroll date following the Start Date and (B) half on the first regular payroll date following six months from the Start Date (each such date a “Sign-on Bonus Date”). In the event that Executive’s employment is terminated by Executive without Good Reason (as defined below) or by the Company without Cause (as defined below): (A) prior to the twelve (12) month anniversary of the applicable Sign-on Bonus Date, then Executive hereby agrees to repay one hundred percent (100%) of the applicable Signing Bonus (on a net after-tax basis), or (B) on or after the twelve (12) month anniversary of the applicable Sign-on Bonus Date but prior to the twenty-four (24) month anniversary of the applicable Sign-on Bonus Date, then Executive hereby agrees to repay fifty percent (50%) of the applicable Signing Bonus (on a net after-tax basis). Such repayment of the Signing Bonus shall be calculated separately for each portion of the Signing Bonus and shall occur no later than thirty (30) days after the Executive’s termination date. ii. Initial Equity Awards. No later than February 28, 2026, Executive will be granted the following stock awards: (A) an award of performance stock units (“PSUs”) under the Company’s fiscal 2026-28 performance stock unit program (the “2026 PSP”), the target number of shares provided in such award having a value equal to $1,500,000 (based on the fair market value of the Company’s common stock on the Grant Date (as defined below)). Vesting under the 2026 PSP will occur following the completion of the three-year period ending on December 31, 2028, and will be based on the Company’s achievement during such three-year period of certain performance objectives that were approved by the Committee. The number of shares that may vest under the plan, if any, can range from 50% to 200% of the target number of shares. (B) an award of restricted stock units to acquire shares of the Company’s common stock (“RSUs”) having a value equal to $1,500,000 (based on the fair market value of the Company’s common stock on the Grant Date). The RSUs will vest in three equal annual installments beginning on the first anniversary of the Grant Date. As used in this Agreement, “Grant Date” means the actual date on which an equity award is granted. b. Ongoing Compensation: In consideration for Executive’s ongoing
3 employment with the Company, Executive shall receive the following: i. Base Salary. The Company will pay Executive a base salary of $650,000 per year (as increased, from time to time, the “Base Salary”), payable in accordance with Inspire’s standard payroll practices. The Base Salary shall be subject to annual review and possible adjustment by the Board’s Organization and Compensation Committee (the “Committee”) in its discretion. ii. Incentive Awards. Executive will be eligible to receive discretionary annual cash bonuses and/or long-term incentive compensation (“Incentive Awards”) pursuant to the terms and conditions of Inspire’s management incentive program (the “MIP”) and/or Inspire’s long term incentive plan (jointly, “Incentive Plans”) which may be adopted, amended, supplemented, terminated and/or replaced by Inspire from time to time. With reference to the Incentive Plans, the parties understand as follows: (A) Annual Cash Bonus. For each fiscal year completed during the Executive’s employment under this Agreement, Executive will be eligible to earn an annual bonus (each, an “Annual Bonus”) under the MIP, or such other successor plan or program as may be in effect from time to time. The Executive’s target Annual Bonus shall be 70% of the Base Salary (the “Target Bonus Amount”), subject to the achievement of predetermined performance goals or other business objectives. Any Annual Bonus for the Executive’s initial year of employment with the Company shall be prorated based on the Start Date. (B) Annual Long-Term Incentives. Beginning with the Company’s 2027 fiscal year, Executive shall be eligible to receive discretionary annual long- term incentive awards. The form, amount, and timing of such long-term incentive compensation, if any, shall be determined by the Committee in its discretion. (C) General Terms. I. Executive’s eligibility to receive Incentive Awards will be determined by the Board or such other committee as may have responsibility for making that determination, in its sole discretion. II. The Incentive Plans are not necessarily all-inclusive because circumstances which Inspire has not anticipated may arise. Inspire may interpret or vary from the Incentive Plans if, in its opinion, the circumstances warrant it. Further, Executive’s eligibility to receive Incentive Awards may be affected in the event Inspire has determined that such Incentive Awards would be in violation of law or reasonably create an adverse effect on Inspire or its obligations or agreements including, without limitation, leaving Inspire with insufficient liquidity (including adequate reserves) to carry on its business and pay its debt in the ordinary course. III. Inspire reserves the right to make any changes at any time to the Incentive Plans by adding to, deleting from or otherwise amending any portion of them, with or without notice to Executive, provided, however, that if Executive has been awarded non-cash compensation pursuant to such plans, then Executive shall receive notice of any changes to the plan as may be required by applicable law, and provided, further, that any
4 such changes are applicable to participants in the Incentive Plans generally and not specific to Executive. IV. Any questions regarding the computation of Incentive Awards under the Incentive Plans will be conclusively determined by the Incentive Plan administrator, as defined therein, pursuant to the terms and conditions of the Incentive Plans. c. Expenses. Inspire will reimburse Executive for any and all ordinary, necessary and reasonable business expenses that Executive incurs in connection with the performance of Executive’s duties under this Agreement, including entertainment, travel and miscellaneous expenses. Executive must obtain proper approval for such expenses pursuant to the Company’s policies and procedures and Executive must provide the Company with documentation for such expenses in a form sufficient to sustain Inspire’s deduction for such expenses under the Internal Revenue Code of 1986, as amended (the “Code”). d. Time Off. Executive will be entitled to time off with or without pay in accordance with Inspire’s policies in effect at any particular time. e. Health, Disability and Life Insurance, and Other Executive Benefit Plans. Inspire will provide Executive with the same health, disability, and life insurance coverage provided generally to other full-time salaried employees of Inspire, and with other employee benefit plans which are presently existing or which may be established in the future by Inspire for its full-time salaried employees, subject to the terms and conditions of the applicable benefit plans. f. Indemnification. The Company and Executive will enter into the Company’s standard indemnification agreement pursuant to which the Company will defend, indemnify and hold Executive harmless from costs, expenses, damages and other liability incurred by Executive as a result of performing services to Inspire, subject to the limitations and other terms and conditions of applicable Delaware statutes and Inspire’s Articles of Incorporation or Bylaws. g. Changes in Benefit Plans. It is understood that no references in this Agreement to particular employee benefit plans established or maintained by Inspire are intended to change the terms and conditions of these plans or to preclude Inspire from amending or terminating any such benefit plans. h. Withholding; Taxes. Inspire may withhold from any compensation, reimbursements and benefits payable to Executive all federal, state, city and other taxes as shall be required pursuant to any law or governmental regulation or ruling, as well as other standard withholdings and deductions. Executive recognizes that some of the payments and some of the benefits which Executive receives under this Agreement will constitute compensation, and will be fully taxable to Executive. Executive agrees to properly report such payments and benefits on Executive’s applicable income tax returns and to pay all appropriate taxes. 5. Termination. Executive’s employment may be terminated at any time as follows:
5 a. Death. Executive’s employment shall automatically terminate upon Executive’s death. b. Disability. Either party may terminate Executive’s employment at any time, upon written notice to the other party if Executive sustains a disability which precludes Executive from performing the essential functions of Executive’s job, with or without reasonable accommodations, as defined by applicable state and federal disability laws. Executive shall be presumed to have such a disability for purposes of this Agreement if Executive qualifies, because of illness or incapacity, to begin receiving disability income insurance payments under any long-term disability income insurance policy that Inspire maintains for the benefit of Executive. If Executive does not qualify for such payments, Executive shall nevertheless be presumed to have such a disability if Executive is substantially incapable of performing the essential functions of Executive’s job for a period of more than twenty-six (26) consecutive weeks, with or without a reasonable accommodation, or for shorter non-consecutive periods aggregating thirty-six (36) weeks in any twelve (12) month period. c. With Cause. Inspire may terminate Executive’s employment at any time, with “Cause”, upon written notice to Executive. “Cause” shall be defined as: i. Executive’s material breach of any of Executive’s obligations under this Agreement, or Executive’s repeated failure or refusal to perform or observe Executive’s duties, responsibilities and obligations as an Executive of Inspire, for reasons other than disability; ii. any material dishonesty or other breach of the duty of loyalty of Executive affecting Inspire or any customer, vendor or employee of Inspire; iii. use of alcohol or other drugs in a manner which affects the performance of Executive’s duties, responsibilities and obligations as an employee of Inspire; iv. conviction of, or a plea of guilty or nolo contendere to, a charge of commission of a felony or of any crime involving misrepresentation, moral turpitude or fraud; v. commission by Executive of any other willful or intentional act which injures the reputation, business or business relationships of Inspire; or vi. the existence of any court order or settlement agreement prohibiting Executive’s continued employment with Inspire. A matter of the type described in this Paragraph 5(c) shall be “material” if such matter, alone or together with other such matters, is material. d. Without Cause. Inspire may terminate Executive’s employment at any time, without Cause, upon one (1) month’s written notice to Executive. Inspire may, in its sole discretion, opt not to have Executive provide active employment services during some or all of the notice period, and place Executive on a paid leave of absence for some or all of the notice period.
6 e. Voluntary Resignation. Executive may, upon two (2) weeks’ written notice to Inspire, terminate Executive’s employment at any time for no reason. In addition, Executive may terminate Executive’s employment for Good Reason. For purposes of this Agreement, “Good Reason” shall mean: i. a material reduction, without Executive’s consent, in Executive’s duties or responsibilities; ii. a material reduction, without Executive’s consent, of the Base Salary, unless such reduction is part of an overall reduction in salary for executive employees and Executive’s reduction is proportionate to the overall reduction in salary; iii. the Company’s moving Executive’s place of employment, without Executive’s consent, more than fifty (50) miles from the place of Executive’s employment prior to such move, although business travel shall not be deemed to be a move of Executive’s place of employment; or iv. the Company’s material breach of this Agreement. Notwithstanding the foregoing, Executive may only terminate Executive’s employment for Good Reason following the occurrence of one or more of the foregoing conditions, subject to Executive first providing written notice of Executive’s claimed Good Reason to the Company within ninety (90) days after the initial existence of such condition and the Company failing to cure the basis for such claimed Good Reason within thirty (30) days following such notice. 6. Payments and Benefits Upon Termination. Upon the termination of Executive’s employment, Executive shall only be entitled to the following payments and benefits: a. Disability; Death. If Executive’s employment is terminated due to the disability or death of Executive, regardless of the date of termination, Executive or Executive’s estate or heirs, as appropriate, shall be paid (i) any portion of Base Salary through the date of termination not theretofore paid; (ii) any cash bonus either accrued in accordance with the terms of the relevant plan or previously awarded but not yet paid to Executive at the time of Executive’s death or disability; (iii) any benefits payable under any disability or life insurance policy maintained by Inspire for the benefit of Executive at the time of the termination of employment, subject to the terms and conditions of such policies; (iv) any unpaid expense reimbursement; and (v) Executive’s or Executive’s estate or heirs, as appropriate, other vested benefits, if any, under any of Inspire’s Incentive Plans or any of Inspire’s other employee benefit plans (e.g., 401(k) plan), subject to the terms and conditions of those plans. b. Termination by Inspire For Cause; Voluntary Resignation. If Inspire terminates Executive’s employment for Cause, or if Executive resigns, regardless of the date of termination, Executive shall be paid (i) any portion of Base Salary through the date of termination not theretofore paid; (ii) any unpaid expense reimbursement; and (iii) Executive’s other vested benefits, if any, under any of Inspire’s Incentive Plans or any of Inspire’s other employee benefit
7 plans (e.g., 401(k) plan), subject to the terms and conditions of those plans. c. Termination by Inspire Without Cause. If the Company terminates Executive’s employment without Cause, including following a Change of Control (as defined below), regardless of the date of termination, Executive shall be paid the same payments and benefits as set forth in Paragraph 6(a) above. In addition, Inspire shall, subject to Paragraph 10 and subject to Executive’s execution and non-revocation of a release of claims, to the full extent permitted by law, in a form reasonably satisfactory to Inspire in accordance with Paragraph 10(c) (the “Release”), which assures, among other things, that Executive will not commence any type of litigation or assert other claims as a result of the termination (except to enforce Executive’s rights under this Agreement): i. pay to the Executive an amount equal to the sum of (A) twelve (12) months of the Base Salary as of the date of termination and (B) the Target Bonus Amount, in substantially equal installments during the period beginning on the date of termination and ending on the twelve (12) month anniversary of the date of termination in accordance with the Company’s regular payroll practice as of the date of termination. ii. continue to provide, subject to the Executive’s valid election to continue healthcare coverage under COBRA, the Executive and the Executive’s eligible dependents with payment of premiums for any COBRA benefits during the period commencing on the date of termination and ending on the twelve (12) month anniversary of the date of termination. iii. in the event that such termination of employment is due to a Change of Control and occurs within the twelve (12) month period immediately following a Change of Control, (such period, the “COC Period”), such termination will cause each of Executive’s equity awards that are granted on or following the Start Date to immediately become fully vested (except in the case of performance stock unit awards which shall be subject to change of control provisions as set forth in the applicable form of award agreement for such awards). d. Change of Control Definition. For purposes of this Agreement, “Change of Control” means the occurrence of any of the following: (1) a sale by shareholders of the Company of a substantial portion of their stock in the Company, or a merger, reorganization or consolidation, whereby the Company’s equity holders existing immediately prior to such sale, merger, reorganization or consolidation do not, immediately after consummation of such sale, reorganization, merger or consolidation, own more than fifty percent (50%) of the combined voting power of the surviving entity’s then outstanding voting securities entitled to vote generally in the election of directors, but only if such event results in a change in Board composition such that the directors immediately preceding such events do not comprise a majority of the Board following such event; or (2) the sale or other disposition of all or substantially all of the Company’s assets to an entity in which the Company, any subsidiary of the Company, or the Company’s equity holders existing immediately prior to such sale beneficially own less than fifty percent (50%) of the combined voting power of such acquiring entity’s then outstanding voting securities entitled to vote generally in the election of directors
8 but only if such event results in a change in Board composition such that the directors immediately preceding such events do not comprise a majority of the Board following such event. 7. Business Protections. Inspire has many confidential and proprietary business interests and other information relating to its products, services and customers, which it needs to adequately protect. For this reason, its willingness to enter into this Agreement is contingent upon Executive’s acceptance of the covenants set forth in Paragraph 8 below. Executive understands that the business protections in Paragraph 8 will apply throughout Executive’s employment, and as applicable, will continue to apply thereafter even if Executive’s employment is terminated under Paragraph 5 of this Agreement, regardless of the reason for or timing of the termination. 8. Post-Employment Restrictions. a. Restrictions on Competition. Executive agrees that while employed by Inspire, Executive will not be employed by or otherwise perform services for an organization which is engaged in the research and development, marketing, or distribution of a product or treatment which is the same as or which competes with any product or treatment offered or being developed by Inspire during, or as of the date of termination of, Executive’s employment with Inspire. b. Prohibition on Solicitation of Inspire Employees. Executive agrees that at all times while employed by Inspire, and for twelve (12) months thereafter, Executive will not solicit, cause to be solicited, or participate in or promote the solicitation of any person to terminate that person’s employment with Inspire or to breach that person’s employment agreement with Inspire. c. Post-Employment Disclosure. In the event Executive’s employment with Inspire terminates, Executive agrees that during the term of the restrictions described in Paragraph 8(a) above, Executive will promptly inform Inspire of the identity of any new employer, the job title of Executive’s new position, and a description of any services to be rendered to that employer. In addition, Executive agrees to respond within ten (10) days to any written request from Inspire for further information concerning Executive’s work activities sufficient to provide Inspire with assurances that Executive is not violating any of the obligations Executive has undertaken in this Agreement. d. Prohibition on Disclosure of Confidential Information. Executive shall hold the Confidential Information (as defined in Paragraph 8(e)) including trade secrets and/or data, in the strictest confidence and will never, without prior written consent of the Company, directly or indirectly disclose, assign, transfer, convey, communicate to or use for Executive’s own or another’s benefit, or directly or indirectly disclose, assign, transfer, convey, communicate to or use by a competitor of the Company or any other person or entity, including, but not limited to, the press, other professionals, corporations, partnerships or the public, at any time during Executive’s employment with the Company or at any time after Executive’s termination of employment with the Company, regardless of the reason for the Executive’s termination,
9 whether voluntary or involuntary. Executive further promises and agrees that he will faithfully abide by any rules, policies, practices or procedures existing or which may be established by the Company for insuring the confidentiality of the Confidential Information, including, but not limited to, rules, policies, practices or procedures: i) Limiting access to authorized personnel; ii) Limiting copying of any writing, data or recording; iii) Requiring storage of property, documents or data in secure facilities provided by the Company and limiting safe or vault lock combinations or keys to authorized personnel; and/or iv) Checkout and return or other procedures promulgated by the Company from time to time. The Executive acknowledges that the Company has provided the Executive with the following notice of immunity rights in compliance with the requirements of the Defend Trade Secrets Act of 2016: (A) the Executive shall not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of Confidential Information that is made in confidence to a federal, state or local government official or to an attorney solely for the purpose of reporting or investigating a suspected violation of law, (B) the Executive shall not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of Confidential Information that is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal and (C) if the Executive files a lawsuit for retaliation by the Company for reporting a suspected violation of law, the Executive may disclose the Confidential Information to the Executive’s attorney and use the Confidential Information in the court proceeding, if the Executive files any document containing the Confidential Information under seal, and does not disclose the Confidential Information, except pursuant to court order. e. Definition of Confidential Information. For the purposes of this Agreement, “Confidential Information” means any information not generally known to the public and proprietary to or in the possession of the Company and includes, without limitation, trade secrets, inventions, and information pertaining to research, development, purchasing, marketing, selling, accounting, licensing, business systems, business techniques, customer lists, prospective customer lists, price lists, business strategies and plans, pending patentable materials and/or designs, design documentation, documentation of meetings, tests and/or test standards, or manuals whether in document, electronic, computer or other form. For example, Confidential Information may be contained in the Company’s customer lists, prospective customer lists, the particular needs and requirements of customers, the particular needs and requirements of prospective customers, and the identity of customers or prospective customers. Information shall be treated as Confidential Information irrespective of its source and any information which is labeled or marked as being “confidential” or “trade secret” shall be presumed to be Confidential Information. The definition of Confidential Information as set forth in this paragraph is not intended to be complete. From time to time during the term of Executive’s employment, Executive may gain access to other information not generally known to the public and
10 proprietary to or in the possession of the Company concerning the Company’s businesses that is of commercial value to the Company, which information shall be included in the definition in this paragraph, even though not specifically listed above. The definition of Confidential Information applies to any form in which the subject information, trade secrets, or data may appear, whether written, oral, or any other form of recording or storage. f. Restrictions. The restrictions herein provided shall not apply with respect to Confidential Information which: (A) is or becomes a part of the public domain without breach of this Agreement by the Executive; or (B) is disclosed pursuant to judicial action or government regulations, provided the Executive notifies the Company prior to such disclosure and cooperates with the Company in the event the Company elects to legally contest and avoid such disclosure. g. Certain Company Remedies. The Executive acknowledges that the Company will suffer irreparable harm if the Executive breaches Paragraphs 8(a), 8(b) and/or 8(d). Accordingly, the Company shall be entitled to equitable relief, including but not limited to, an injunction, enjoining or restraining Executive from any violation of Paragraphs 8(a), 8(b) and/or 8(d) of this Agreement, in addition to any other remedies the Company is entitled to at law or in equity. In the event the Company pursues any remedies pursuant to this Paragraph 8(f) and prevails in such a proceeding, the Executive shall pay the Company’s reasonable attorneys’ fees in connection with such proceeding. Should the Company not prevail in such a proceeding, the Company shall pay the Executive’s reasonable attorneys’ fees in connection with such proceeding. Furthermore, should a court of competent jurisdiction determine that the Executive has breached Paragraphs 8(a), 8(b), and/or 8(d), the restrictions in such Paragraphs will be extended by the period during which the Executive was in breach. 9. Parachute Payments. a. Notwithstanding any other provisions of this Agreement, in the event that any payment or benefit by the Company or otherwise to or for the benefit of the Executive, whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise (all such payments and benefits, including the payments and benefits under Paragraph 6 above, being hereinafter referred to as the “Total Payments”), would be subject (in whole or in part) to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then the Total Payments shall be reduced (in the order provided in Paragraph 9(b) below) to the minimum extent necessary to avoid the imposition of the Excise Tax on the Total Payments, but only if (i) the net amount of such Total Payments, as so reduced (and after subtracting the net amount of federal, state and local income and employment taxes on such reduced Total Payments and after taking into account the phase out of itemized deductions and personal exemptions attributable to such reduced Total Payments), is greater than or equal to (ii) the net amount of such Total Payments without such reduction (but after subtracting the net amount of federal, state and local income and employment taxes on such Total Payments and the amount of the Excise Tax to which the Executive would be subject in respect of such unreduced Total Payments and after taking into account the phase out of itemized deductions and personal exemptions attributable to such unreduced Total Payments).
11 b. The Total Payments shall be reduced in the following order: (i) reduction on a pro-rata basis of any cash severance payments that are exempt from Section 409A of the Code (“Section 409A”), (ii) reduction on a pro-rata basis of any non-cash severance payments or benefits that are exempt from Section 409A, (iii) reduction on a pro-rata basis of any other payments or benefits that are exempt from Section 409A, and (iv) reduction of any payments or benefits otherwise payable to the Executive on a pro-rata basis or such other manner that complies with Section 409A; provided, in case of subclauses (ii), (iii) and (iv), that reduction of any payments attributable to the acceleration of vesting of Company equity awards shall be first applied to Company equity awards that would otherwise vest last in time. c. The Company will select an adviser with experience in performing calculations regarding the applicability of Section 280G of the Code and the Excise Tax, provided that the adviser’s determination shall be made based upon “substantial authority” within the meaning of Section 6662 of the Code, (the “Independent Advisors”) to make determinations regarding the application of this Paragraph 9. The Independent Adviser shall provide its determination, together with detailed supporting calculations and documentation, to the Executive and the Company within fifteen (15) business days following the date on which the Executive’s right to the Total Payments is triggered, if applicable, or such other time as requested by the Executive (provided, that the Executive reasonably believes that any of the Total Payments may be subject to the Excise Tax) or the Company. The costs of obtaining such determination and all related fees and expenses (including related fees and expenses incurred in any later audit) shall be borne by the Company. Any good faith determinations of the Independent Adviser made hereunder shall be final, binding and conclusive upon the Company and the Executive. d. In the event it is later determined that to implement the objective and intent of this Paragraph 9, (i) a greater reduction in the Total Payments should have been made, the excess amount shall be returned promptly by the Executive to the Company or (ii) a lesser reduction in the Total Payments should have been made, the excess amount shall be paid or provided promptly by the Company to the Executive, except to the extent the Company reasonably determines would result in imposition of an excise tax under Section 409A. 10. Section 409A. a. General. The parties hereto acknowledge and agree that, to the extent applicable, this Agreement shall be interpreted in accordance with, and incorporate the terms and conditions required by, Section 409A. Notwithstanding any provision of this Agreement to the contrary, in the event that the Company determines that any amounts payable hereunder will be immediately taxable to the Executive under Section 409A, the Company reserves the right (without any obligation to do so or to indemnify the Executive for failure to do so) to (i) adopt such amendments to this Agreement and appropriate policies and procedures, including amendments and policies with retroactive effect, that the Company determines to be necessary or appropriate to preserve the intended tax treatment of the benefits provided by this Agreement, to preserve the economic benefits of this Agreement and to avoid less favorable accounting or tax consequences for the Company and/or (ii) take such other actions as the Company
12 determines to be necessary or appropriate to exempt the amounts payable hereunder from Section 409A or to comply with the requirements of Section 409A and thereby avoid the application of penalty taxes thereunder. No provision of this Agreement shall be interpreted or construed to transfer any liability for failure to comply with the requirements of Section 409A from the Executive or any other individual to the Company or any of its affiliates, employees or agents. b. Separation from Service under Section 409A. Notwithstanding any provision to the contrary in this Agreement: (i) no amount that constitutes “nonqualified deferred compensation” under Section 409A shall be payable pursuant to Paragraph 6 unless the termination of the Executive’s employment constitutes a “separation from service” within the meaning of Section 1.409A-1(h) of the Department of Treasury Regulations; (ii) for purposes of Section 409A, any right to receive installment payments pursuant to this Agreement shall be treated as a right to receive a series of separate and distinct payments; and (iii) to the extent that any reimbursement of expenses or in-kind benefits constitutes “deferred compensation” under Section 409A, such reimbursement or benefit shall be provided no later than December 31 of the year following the year in which the expense was incurred. The amount of expenses reimbursed in one year shall not affect the amount eligible for reimbursement in any subsequent year. The amount of any in-kind benefits provided in one year shall not affect the amount of in- kind benefits provided in any other year. Notwithstanding any provision to the contrary in this Agreement, if the Executive is deemed at the time of Executive’s separation from service to be a “specified employee” for purposes of Section 409A(a)(2)(B)(i) of the Code, to the extent delayed commencement of any portion of the termination benefits to which the Executive is entitled under this Agreement is required in order to avoid a prohibited distribution under Section 409A(a)(2)(B)(i) of the Code, such portion of the Executive’s termination benefits shall not be provided to the Executive prior to the earlier of (A) the expiration of the six-month period measured from the date of the Executive’s “separation from service” with the Company (as such term is defined in the Treasury Regulations issued under Section 409A of the Code) or (B) the date of the Executive’s death; upon the earlier of such dates, all payments deferred pursuant to this sentence shall be paid in a lump sum to the Executive, and any remaining payments due under the Agreement shall be paid as otherwise provided herein. c. Release. Notwithstanding anything to the contrary in this Agreement, to the extent that any payments of “nonqualified deferred compensation” (within the meaning of Section 409A) due under this Agreement as a result of the Executive’s termination of employment are subject to the Executive’s execution and delivery of a Release, (i) the Company shall deliver the Release to the Executive within seven (7) days following the date of termination, and (ii) if the Executive fails to execute the Release on or prior to the Release Expiration Date (as defined below) or timely revokes Executive’s acceptance of the Release thereafter, the Executive shall not be entitled to any payments or benefits otherwise conditioned on the Release. For purposes of this Paragraph 10(c), “Release Expiration Date” shall mean the date that is twenty-one (21) days following the date upon which the Company timely delivers the Release to the Executive, or, in the event that the Executive’s termination of employment is “in connection with an exit incentive or other employment termination program” (as such phrase is defined in the Age Discrimination in Employment Act of 1967), the date that is forty-five (45) days following such delivery date. To the extent that any payments of nonqualified deferred
13 compensation (within the meaning of Section 409A) due under this Agreement as a result of the Executive’s termination of employment are delayed pursuant to this Paragraph 10(c), such amounts shall be paid in a lump sum on the first payroll date to occur on or after the 60th day following the date of Executive’s termination of employment, provided that Executive executes and does not revoke the Release prior to such 60th day (and any applicable revocation period has expired). 11. Compensation Recovery. The Executive acknowledges and agrees that, he or she shall, during the Executive’s term of employment and thereafter, take all action necessary or appropriate to comply with the Company’s Recovery of Erroneously Awarded Compensation Policy or similar policy, as may be amended from time to time in the Company’s sole discretion, including, without limitation, entering into any further agreements, amendments or policies necessary or appropriate to implement and/or enforce such policy. The Executive’s obligations under this Paragraph 11 shall survive the termination of this Agreement. 12. Inventions. “Inventions” shall mean any and all inventions, discoveries, ideas, processes, writings, works of authorship, designs, developments and improvements, whether or not protectable under the applicable patent, trademark or copyright statutes, generated, conceived or reduced to practice by the Executive, alone or in conjunction with others, while employed by Inspire. a. Disclosure. Executive agrees to promptly disclose to Inspire in writing all Inventions. b. Ownership, Assignment and Recordkeeping. All Inventions shall be the exclusive property of Inspire. Executive agrees to and hereby does assign all Inventions to Inspire. Executive agrees to keep accurate, complete and timely records of Executive’s Inventions, which records shall be the property of Inspire and shall be retained on Inspire’s premises. c. Cooperation. During and after the termination of Executive’s employment, Executive agrees to give Inspire all cooperation and assistance necessary to perfect, protect, and use its rights to Inventions. Without limiting the generality of the foregoing, Executive agrees to sign all documents, do all things, and supply all information that Inspire may deem necessary to (i) transfer or record the transfer of Executive’s entire right, title and interest in Inventions, and (ii) enable Inspire to obtain patent, copyright or trademark protection for Inventions anywhere in the world. d. Attorney-in-Fact. Executive irrevocably designates and appoints Inspire and its duly authorized officers and agents as attorney-in-fact to act for and in Executive’s behalf and stead to execute and file any lawful and necessary documents, and to do all other lawfully permitted acts, required for the assignment of, application for, or prosecution of any United States or foreign application for letters patent, copyright or trademark with the same legal force and effect as if executed by Executive. e. Waiver. Executive hereby waives and quitclaims to Inspire any and all claims, or any nature whatsoever, which Executive may now have or may hereafter have for
14 infringement of any patent, copyright, or trademark resulting from any Inventions. f. Future Patents. Any Invention relating to the business of Inspire with respect to which Executive files a patent application within one (1) year following termination of Executive’s employment shall be presumed to cover Inventions conceived by Executive during the term of Executive’s employment, subject to proof to the contrary by Executive by good faith, contemporaneous, written and duly corroborated records establishing that such Invention was conceived and made following termination of employment and without using Confidential Information. g. Release or License. If an Invention does not relate to the existing or reasonable foreseeable business interests of Inspire, Inspire may, in its sole and unreviewable discretion, release or license the Invention to the Executive upon written request by the Executive. No release or license shall be valid unless in writing signed by Inspire’s general counsel. h. Notice. Executive is hereby notified that this Agreement and this Paragraph 12 do not apply to any Invention for which no equipment, supplies, facility or trade secret information of Inspire was used and which was developed entirely on the Executive’s own time, and (1) which does not relate (i) directly to the business of Inspire or (ii) to Inspire’s actual or demonstrably anticipated research or development, or (2) which does not result from any work performed by the Executive for Inspire. 13. Miscellaneous. a. Entire Agreement. The terms of this Agreement (together with any other agreements and instruments contemplated by this Agreement or referred to herein) is intended by the parties hereto to be the final expression of their agreement with respect to the employment of Executive by the Company, and supersedes and may not be contradicted by evidence of any prior or contemporaneous agreement. The parties hereto further intend that this Agreement shall constitute the complete and exclusive statement of its terms and that no extrinsic evidence whatsoever may be introduced in any judicial, administrative or other legal proceeding to vary the terms of this Agreement. b. Construction. Each provision of this Agreement shall be interpreted so that it is valid and enforceable under applicable law. If any provision of this Agreement is to any extent invalid or unenforceable under applicable law, that provision will still be effective to the extent it remains valid and enforceable. The remainder of this Agreement also will continue to be valid and enforceable, and the entire Agreement will continue to be valid and enforceable in other jurisdictions. In the event that a court of competent jurisdiction determines that any of the provisions of Paragraphs 8 or 12 of this Agreement are not enforceable for any reason, such court shall reform such provisions to the minimum extent necessary to make them enforceable, it being the intention of the parties that such provisions be enforced to the maximum extent permitted by applicable law. c. Waivers. No term or condition of this Agreement shall be deemed to have
15 been waived, nor shall there be any estoppel to enforce any provisions of this Agreement, except by a statement in writing signed by the party against who enforcement of the waiver or estoppel is sought. A waiver shall operate only as to the specific term or condition waived. No waiver shall constitute a continuing waiver or a waiver of such term or condition for the future unless specifically stated. No single or partial exercise of any right or remedy under this Agreement shall preclude any party from otherwise or further exercising such rights or remedies, or any other rights or remedies granted by law or any other document. d. Captions. The headings in this Agreement are for convenience of reference only and do not affect the interpretation of this Agreement. e. Modifications. This Agreement may not be altered, modified or amended except by an instrument in writing signed by each of the parties hereto. f. Governing Law. The laws of the State of Minnesota shall govern the validity, construction and performance of this Agreement, to the extent not pre-empted by federal law. Any legal proceeding related to this Agreement shall be brought in an appropriate Minnesota court, and each of the parties hereto hereby consents to the exclusive jurisdiction of the courts of the State of Minnesota for this purpose. g. Notices. All notices and other communications required or permitted under this Agreement shall be in writing and provided to the other party either in person, by fax, or by certified mail. Notices to Inspire must be provided or sent to its President and Chief Executive Officer; notices to Executive must be provided or sent to Executive in person or at Executive’s home. h. Survival. Notwithstanding the termination of Executive’s employment and the termination of this Agreement, the terms of this Agreement which relate to periods, activities, obligations, rights or remedies of the parties upon or subsequent to such termination shall survive such termination and shall govern all rights, disputes, claims or causes of action arising out of or in any way related to this Agreement. i. Successors and Assigns. This Agreement shall be binding on and inure to the benefit of Inspire’s successors and assigns. j. Electronic Signatures. The parties agree that this Agreement may be executed and delivered by electronic means, including PDF copies and electronic signature platforms such as DocuSign.
