SAN DIEGO, August 13, 2025 – ARS Pharmaceuticals, Inc. (Nasdaq: SPRY), a biopharmaceutical company dedicated to empowering at-risk patients and their caregivers to better protect patients from allergic reactions that could lead to anaphylaxis, today announced financial results for the second quarter of 2025, and provided an update on the commercial launch of neffy® (epinephrine nasal spray), the first and only FDA-approved and European Commission-approved needle-free epinephrine treatment for Type I allergic reactions, including anaphylaxis.

“The second quarter marks a pivotal inflection point for neffy, highlighted by robust growth in prescriptions driven by expanding payor access and strong sales execution,” said Richard Lowenthal, Co-Founder, President and CEO of ARS Pharma. “As we move through the peak back-to-school prescribing season and with our most recent DTC investment and co-promote partnership, neffy is rapidly establishing itself as a preferred epinephrine option for patients, caregivers and schools. With continued commercial momentum in the U.S. and an expanded global presence marked by EURneffy’s approval in the U.K. and launch in Germany, we are advancing our vision to redefine the standard of care for allergic emergencies while creating lasting value for patients, providers and shareholders alike.”

Second Quarter 2025 Financial Results

•

Revenue: Total revenue for the second quarter of 2025 was $15.7 million, which was comprised of $12.8 million in net product revenue from neffy sales in the U.S., $2.6 million in milestone revenue from ALK-Abelló A/S (ALK) related to the launch of EURneffy® in Germany, and $0.3 million in supply revenue from partners. The cash milestone triggered from ALK to ARS Pharma was $5.0 million, with $2.6 million recognized as revenue and the remaining $2.4 million recorded to the financing liability on the company’s balance sheet.

•

Research and Development (R&D) Expenses: R&D expenses for the second quarter of 2025 were $4.0 million, which was primarily associated with the initiation of the Phase 2b clinical trial in urticaria, the ongoing post-marketing registry study for the treatment of anaphylaxis in oral food challenge or allergen immunotherapy clinics and other development expenses for neffy.

•

Selling, General and Administrative (SG&A) Expenses: SG&A expenses for the second quarter of 2025 were $54.3 million, reflecting the company’s substantial investment in the national direct-to-consumer marketing campaign and continued sales and marketing expenses associated with the U.S. commercialization of neffy. The company is committed to investing in the ongoing promotion of neffy to further enhance patient and physician awareness and to continue accelerating market share.

•

Net Loss: Net loss for the second quarter of 2025 was $44.9 million, or $0.46 per share.

•

Cash Runway: As of June 30, 2025, ARS Pharma had cash, cash equivalents, and short-term investments of $240.1 million, with 98,697,658 shares of common stock outstanding. The company reiterates its guidance that its financial position is expected to support its operating plans for at least the next three years.

neffy Commercial Launch Progress in the United States

•

Prescription growth: neffy two-pack unit weekly volumes have continued to grow, increasing approximately 180% from the end of first quarter of 2025 to the end of second quarter of 2025. Notably, this volume growth pre-dated the company’s rollout of its national DTC campaign.

ARS Pharma’s DTC campaign was rolled out in two stages, beginning in mid-May with connected TV (streaming) and followed by broadcast/linear TV in late June. The campaign has significantly increased consumer awareness since its late second quarter launch, driving added awareness of neffy from a baseline of approximately 20% pre-campaign to 49% in late July. Consistent with the observed time-to-effect during DTC launch campaigns for other pharmaceutical products, further neffy script momentum is expected in the second half of 2025 and beyond.

•

Commercial coverage goal exceeded: 93% commercial coverage, including 57% without prior authorization, has been secured thus far with neffy’s access and approval rates across the major PBMs consistent with the overall epinephrine market. Further, prior authorizations that are still required by a portion of payors under Zinc, a Group Purchasing Organization affiliated with CVS Caremark, one of the largest PBMs in the U.S., are being approved at more than an 80% success rate. Notably, the proportion of neffy dispensed prescriptions that is represented by payors under Zinc is currently in line with the overall epinephrine market despite the requirement for prior authorizations by a portion of payors under Zinc.

•

52% gross-to-net retention for Q2 2025: Payor access has reached a critical milestone, with gross-to-net retention now at projected steady-state levels, where it should remain moving forward even with future coverage decisions by the remaining PBMs.

Additional highlights from the neffy U.S. commercial launch include:

•

HCP adoption: Over 9,700 HCPs have prescribed neffy to date, which represents a 73% increase from April 2025, of which about 70% continue to be among the highest decile prescribing HCPs.

•

Allergist real-world experience: Approximately 2,800 allergists have enrolled in the neffy Experience Program, with approximately 20,000 doses across both 2 mg and 1 mg neffy on hand for in-office use during an anaphylaxis event occurring during oral food challenges or allergen immunotherapy.

•

School access expansion: More than 3,200 schools have opted into the neffyinSchools program, each receiving two cartons (four single-use doses) of neffy 2 mg or 1 mg at no cost for emergency use through the School Health Corp. SHConnect platform.

•

U.S. registry study ongoing: The ARS Pharma post-marketing registry-based randomized controlled study of neffy for the treatment of anaphylaxis in oral food challenge or allergen immunotherapy clinics in the U.S. is ongoing.

“A key factor driving our growth and momentum has been achieving a critical milestone in payor access, which has significantly reduced administrative barriers for providers,” said Eric Karas, Chief Commercial Officer of ARS Pharma. “As the volume of neffy continues to increase, we anticipate that the economic factors for the remaining PBMs will continue to reduce prior authorization requirements. Additionally, the combination of our sales force execution and DTC advertising further positions us for market share growth. This, along with a more seamless physician prescribing experience and enhanced consumer awareness, creates a strong foundation for continued commercial expansion.”

Global Expansion for neffy and EURneffy

•

EURneffy® approved in United Kingdom (U.K.): In July 2025, the U.K. Medicines and Healthcare products Regulatory Agency (MHRA) granted approval for EURneffy 2 mg for the emergency treatment of allergic reactions (anaphylaxis) in adults and children who weigh greater than 30 kg – another major milestone as the first needle-free treatment in the largest market outside the U.S. for epinephrine auto-injector sales. Under the companies’ license agreement, ALK owns the rights to market EURneffy in the U.K. and expects 2 mg product availability beginning late in the second half of 2025.

•

EURneffy® launched in Germany: ALK successfully launched EURneffy® 2 mg in Germany in June 2025, triggering a $5.0 million milestone payment under the two companies’ licensing agreement. This represents the first commercial launch outside the U.S., and we believe it is indicative of the global demand for our intranasal epinephrine product.

•

EURneffy® 1 mg under review by EMA: EURneffy® 1 mg for children weighing 15 to < 30 kg is currently undergoing regulatory review by the European Medicines Agency (EMA), with approval anticipated in the first half of 2026.

•

Additional regulatory approvals anticipated: Regulatory approvals for neffy in Canada (with ALK-Abelló), Japan (in partnership with Alfresa), and Australia (in partnership with CSL), are expected by the end of 2025, with commercial rollouts planned in the first half of 2026. Regulatory approval for neffy in China (in partnership with Pediatrix) is expected in the first half of 2026.

Clinical Expansion of Intranasal Epinephrine Program

•

Phase 2b trial in urticaria initiated: In June 2025, ARS Pharma initiated a Phase 2b clinical trial (NCT06927999) to evaluate its intranasal epinephrine technology as a treatment for acute flares in patients with chronic spontaneous urticaria. The trial is enrolling patients in the U.S. and Europe, with topline data anticipated in the first half of 2026. This program expansion represents a significant opportunity to extend the utility of the company’s intranasal epinephrine technology to a new indication affecting approximately two million people in the U.S. alone.

About neffy®

neffy is a nasal spray used for emergency treatment of allergic reactions including anaphylaxis, in adults and children aged 4 years and older who weigh 33 lbs. or greater.

INDICATION AND IMPORTANT SAFETY INFORMATION FOR neffy (epinephrine nasal spray)

INDICATION

neffy is indicated for emergency treatment of type I allergic reactions, including anaphylaxis, in adult and pediatric patients aged 4 years and older who weigh 33 lbs. or greater.

IMPORTANT SAFETY INFORMATION

neffy contains epinephrine, a medicine used to treat allergic emergencies (anaphylaxis). Anaphylaxis can be life-threatening, can happen in minutes, and can be caused by stinging and biting insects, allergy injections, foods, medicines, exercise, or other unknown causes.

Always carry two neffy nasal sprays with you because you may not know when anaphylaxis may happen and because you may need a second dose of neffy if symptoms continue or come back. Each neffy contains a single dose of epinephrine. neffy is for use in the nose only.

Use neffy right away, as soon as you notice symptoms of an allergic reaction. If symptoms continue or get worse after the first dose of neffy, a second dose is needed. If needed, administer a second dose using a new neffy in the same nostril starting 5 minutes after the first dose. Get emergency medical help for further treatment of the allergic emergency (anaphylaxis), if needed after using neffy.

Tell your healthcare provider if you have underlying structural or anatomical nasal conditions, about all the medicines you take, and about all your medical conditions, especially if you have heart problems, kidney problems, low potassium in your blood, Parkinson’s disease, thyroid problems, high blood pressure, diabetes, are pregnant or plan to become pregnant, or plan to breastfeed.

Tell your healthcare provider if you take or use other nasal sprays or water pills (diuretics) or if you take medicines to treat depression, abnormal heart beats, Parkinson’s disease, heart disease, thyroid disease, medicines used in labor, and medicines to treat allergies. neffy and other medications may affect each other, causing side effects. neffy may affect the way other medicines work, and other medicines may affect how neffy works.

neffy may cause serious side effects. If you have certain medical conditions or take certain medicines, your condition may get worse, or you may have more or longer lasting side effects when you use neffy.

Common side effects of neffy include: nasal discomfort, headache, throat irritation, chest and nasal congestion, feeling overly excited, nervous or anxious, nose bleed, nose pain, sneezing, runny nose, dry nose or throat, tingling sensation, including in the nose, feeling tired, dizziness, nausea, and vomiting.

Tell your healthcare provider if you have any side effects that bother you or that do not go away after using neffy.

These are not all of the possible side effects of neffy. Call your healthcare provider for medical advice about side effects. To report side effects, contact ARS Pharmaceuticals Operations, Inc. at 1-877-MY-NEFFY (877-696-3339) or the FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

About Type I Allergic Reactions Including Anaphylaxis

Type I allergic reactions are serious and potentially life-threatening events that can occur within minutes of exposure to an allergen and require immediate treatment with epinephrine, the only FDA-approved medication for these reactions. While epinephrine auto-injectors have been shown to be highly effective, there are well published limitations that result in many patients and caregivers delaying or not administering treatment in an emergency situation. These limitations include fear of the needle, lack of portability, needle-related safety concerns, lack of reliability, and complexity of the devices. There are approximately 40 million people in the United States who experience Type I allergic reactions. Of this group, over the last three years, approximately 20 million people have been diagnosed and treated for severe Type I allergic reactions that may lead to anaphylaxis, but (in 2023, for example) only 3.2 million filled their active epinephrine auto-injector prescription, and of those, only half consistently carry their prescribed auto-injector. Even if patients or caregivers carry an auto-injector, more than half either delay or do not administer the device when needed in an emergency.

About ARS Pharmaceuticals, Inc.

ARS Pharma is a biopharmaceutical company dedicated to empowering at-risk patients and their caregivers to better protect patients from allergic reactions that could lead to anaphylaxis. The Company is commercializing neffy® (trade name EURneffy® in the EU), an epinephrine nasal spray indicated in the U.S. for emergency treatment of Type I allergic reactions, including anaphylaxis, in adult patients and pediatric patients 4 years of age and older who weigh 33 lbs. or greater, and in the EU for emergency treatment of allergic reactions (anaphylaxis) due to insect stings or bites, foods, medicinal products, and other allergens as well as idiopathic or exercise induced anaphylaxis in adults and children who weigh 30 kg or greater.
