Statement Regarding Use of Non-GAAP Financial Measures

To supplement the consolidated financial results prepared in accordance with Generally Accepted Accounting Principles ("GAAP"), the Company uses certain non-GAAP historical financial measures. Management makes adjustments to the GAAP measures for items (both charges and gains) that (a) do not reflect the core operational activities of the Company, (b) are commonly adjusted within the Company's industry to enhance comparability of the Company's financial results with those of its peer group, or (c) are inconsistent in amount or frequency between periods (albeit such items are monitored and controlled with equal diligence relative to core operations). The Company uses the term "Non-GAAP" to exclude external acquisition-related costs incurred to effect a business combination; amortization of intangible assets acquired in a business combination, asset purchase transaction or other contractual relationship; impairment of goodwill and intangible assets; certain in-process R&D charges; fair value adjustments to contingent consideration liabilities and pre-acquisition contingencies arising from a business combination; integration and transition costs related to business combinations; fair market value adjustments to inventories acquired in a business combination or asset purchase transaction; restructuring charges, duplicative operating expenses, or asset write-offs (or reversals) associated with exiting or significantly downsizing a business; gain or loss from the sale of a business; gain or loss on the mark-to-market adjustment, impairment, or sale of long-term investments; mark-to-market adjustments on derivative instruments that hedge income or expense exposures in a future period; significant legal litigation costs and/or settlement expenses or proceeds legal and other associated expenses that are both unusual and significant related to governmental or internal inquiries; and significant discrete income and other tax adjustments related to transactions as well as changes in estimated acquisition-date tax effects associated with business combinations, and the impact from implementation of tax law changes and settlements. See “GAAP to Non-GAAP

Graphic Reconciliations” for a reconciliation of each non-GAAP measure presented to the comparable GAAP financial measure.

In addition, in order to remove the impact of fluctuations in foreign currency exchange rates, the Company also presents certain net sales information on a constant currency basis, which represents the outcome that would have resulted had exchange rates in the current period been the same as the average exchange rates in effect in the comparable prior period.  See “Reported Sales vs. Prior Periods” for a presentation of certain net sales information on a reported, GAAP and a constant currency basis.

While we execute commercially, we continue to successfully invest in and advance our robust pipeline of novel, promising platform technologies that we believe can significantly expand our addressable markets and leverage our commercial platform to fundamentally transform our company over time.

We believe the strong financial profile and capital position we’ve built provides a solid foundation that has allowed us to remain on offense when it comes to successfully investing for our future, leaving us well-positioned for the next phase of our pioneering journey as we target clinical, regulatory, and commercial milestones this year and the years ahead.

Graphic

Our mission is to disrupt conventional treatment paradigms to advance the existing standard of care and enrich the lives and treatment alternatives for patients worldwide suffering from sight-threatening chronic eye diseases. We believe our platforms and product candidates have the ability to generate a robust cadence of new product introductions over the coming years that can generate layers of future growth.

Graphic Our foundational iStent micro-surgical device platform primarily involves the insertion of a micro-scale device designed to reduce
IOP by restoring the natural aqueous humor outflow pathways for patients suffering from glaucoma. We believe our iStent portfolio is the industry’s most comprehensive offering of minimally-invasive, tissue-sparing glaucoma solutions, supporting our goal to provide a full range of options to fit
surgeons’ individual glaucoma treatment algorithms that offer the best short- and long-term benefit-to-risk calculus at every stage of disease progression, from ocular hypertension through refractory disease, and in both combo-cataract and standalone procedures. We are proud to be the corporate pioneer and global market leader in MIGS, with our family of iStent technologies supported by approximately 300 peer-reviewed publications, 20+ years of clinical and commercial experience, and 1+ million iStent devices implanted worldwide since our inception.

iDose Sustained-Release Procedural Pharmaceuticals

Our iDose sustained-release procedural pharmaceutical platform consists of a targeted, minimally-invasive, injectable implant designed to deliver therapeutic levels of medication from within the eye for extended periods of time. Designed to address ubiquitous patient non-adherence and chronic side effects associated with topical medications by providing 24/7, long-duration, robust efficacy with minimal side effects. Given our development success to date with iDose TR, we continue to invest resources to expand our pharmaceutical development capabilities and develop future iDose solutions.

iLink Bio-Activated Pharmaceuticals

Our iLink bio-activated pharmaceutical platform consists of novel single-use drug formulations that are bio-activated by our proprietary systems through the delivery of ultraviolet light to the cornea to induce a biochemical reaction called corneal cross-linking designed to strengthen, stabilize, and reshape the cornea. Even though keratoconus is a serious sight-threatening disease and the leading cause of full thickness corneal transplants in the U.S., we believe it remains vastly undertreated. This undertreatment is due primarily to under-diagnosis and the historical lack of an effective solution. In order to maximize the availability of this important Photrexa therapy for patients, we have made substantial investments and executed upon a number of strategies designed to expand our commercial organization, lower the barriers for adoption by practices, increase awareness of keratoconus across the optometric and ophthalmic community, streamline the referral patterns, and train corneal health professionals on our iLink procedure.

Graphic

iLution Transdermal Pharmaceuticals

Our iLution transdermal pharmaceutical platform, which consists of patented cream-based drug formulations, are applied to the outer surface of the eyelid for dropless transdermal delivery of pharmaceutically active compounds for the treatment of eye disorders. We believe iLution’s differentiated delivery approach on the eyelid may offer significant advantages over traditional topical delivery, including the potential for easier administration, faster onset of action, and fewer side effects, such as reduced preservative induced corneal and conjunctival sequalae, all of which can help contribute to better compliance and improved patient outcomes.

Retina XR Bio-Erodible Sustained-Release Pharmaceuticals

Our bio-erodible sustained release pharmaceutical platform, known as Retina XR, is designed to treat retinal diseases, the largest market in ophthalmology today. The goal of these investigational programs is to provide retinal specialists and their patients with novel sustained pharmaceutical treatment options that offer a meaningfully longer duration-of-effect than the current standard of care dominated by short-lasting biological injections that often impose tremendous treatment burdens on patients because of the high-frequency of required treatments.

Our Other Novel Complimentary Ophthalmic Technologies

Radius XR™: The Radius XR platform is a novel portable vision diagnostic and patient engagement system designed to enable more efficient detection of eye disease and better management and treatment of sight-threatening conditions. It combines medical-grade diagnostics, business management tools and patient education resources within a wearable spatial computing device. This comprehensive hardware and software system provides the tools for medical professionals to diagnose patients accurately, enhance patient engagement and reduce staff workload. It enables patients to perform self-guided vision tests with minimal supervision, aiding in eye care practices' flow, efficiency and patient experience. In July 2023, Glaukos entered into a collaboration and marketing agreement with Radius XR, Inc., whereby Glaukos became the exclusive sales agent to market, promote and solicit orders for the Radius XR system within the United States.

Graphic

Developed by Glaukos in partnership with ophthalmic surgeons, iAccess is a precision blade designed to cut trabecular meshwork tissue, thereby allowing aqueous to flow directly into Schlemm’s canal. Goniotomy with iAccess is designed to provide the surgeon versatility in surgical technique, allowing the surgeon to determine what is best suited for the patient, whether it be multiple small incisions spanning over several clock hours that preserve up to 95% more anatomy, or an extensive opening to Schlemm’s canal.

Graphic

iPRIME is a novel, truly minimally-invasive viscoelastic delivery system that further supports the needs of physicians and patients by providing the delivery of viscoelastic during ophthalmic surgery. This technology further expands Glaukos’ broad portfolio of innovative ophthalmic solutions and is consistent with our longstanding position on the value of minimally-invasive therapies. We believe iPRIME will be another important tool that supports the needs of physicians and patients.

Statement Regarding Use of Non-GAAP Financial Measures

To supplement the consolidated financial results prepared in accordance with Generally Accepted Accounting Principles ("GAAP"), the Company uses certain non-GAAP historical financial measures. Management makes adjustments to the GAAP measures for items (both charges and gains) that (a) do not reflect the core operational activities of the Company, (b) are commonly adjusted within the Company's industry to enhance comparability of the Company's financial results with those of its peer group, or (c) are inconsistent in amount or frequency between periods (albeit such items are monitored and controlled with equal diligence relative to core operations). The Company uses the term "Non-GAAP" to exclude external acquisition-related costs incurred to effect a business combination; amortization of intangible assets acquired in a business combination, asset purchase transaction or other contractual relationship; impairment of goodwill and intangible assets; certain in-process R&D charges; fair value adjustments to contingent consideration liabilities and pre-acquisition contingencies arising from a business combination; integration and transition costs related to business combinations; fair market value adjustments to inventories acquired in a business combination or asset purchase transaction; restructuring charges, duplicative operating expenses, or asset write-offs (or reversals) associated with exiting or significantly downsizing a business; gain or loss from the sale of a business; gain or loss on the mark-to-market adjustment, impairment, or sale of long-term investments; mark-to-market adjustments on derivative instruments that hedge income or expense exposures in a future period; significant legal litigation costs and/or settlement expenses or proceeds; legal and other associated expenses that are both unusual and significant related to governmental or internal inquiries; and significant discrete income and other tax adjustments related to transactions as well as changes in estimated acquisition-date tax effects associated with business combinations, and the impact from implementation of tax law changes and settlements. See “Primary GAAP to Non-GAAP Reconciliations” for a reconciliation of each non-GAAP measure presented to the comparable GAAP financial measure.   Beginning in the second quarter of 2022, we no longer exclude certain upfront and contingent milestone payments in connection with collaborative and licensing arrangements and certain in-process R&D charges for non-GAAP reporting and disclosure purposes.

In addition, in order to remove the impact of fluctuations in foreign currency exchange rates, the Company also presents certain net sales information on a constant currency basis, which represents the outcome that would have resulted had exchange rates in the current period been the same as the average exchange rates in effect in the comparable prior period.  See “Additional GAAP to Non-GAAP Reconciliations” for a presentation of certain net sales information on a reported, GAAP and a constant currency basis.
