$32.5 million in revenue, including $31.3 million in neffy U.S. net product revenue in third quarter of 2025

Continued U.S. product growth driven by direct-to-consumer (DTC) investments and real-world evidence, expected to accelerate with seamless prescribing experience

Conference call to be held today, November 10, 2025, at 5:30 a.m. PT / 8:30 a.m. ET

SAN DIEGO, November 10, 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 third quarter of 2025, and provided an update on the commercial launch of neffy® (epinephrine nasal spray), the first and only FDA- and European Commission-approved needle-free epinephrine treatment for Type I allergic reactions, including anaphylaxis.

“We are executing our commercial strategy across multiple fronts, with each element reinforcing the others to drive momentum,” said Richard Lowenthal, Co-Founder, President and CEO of ARS Pharma. “Our direct-to-consumer campaigns are generating measurable increases in patient awareness; real-world evidence data are further strengthening prescriber confidence in neffy’s effectiveness; and we are implementing advertising programs such as a free virtual prescriber option and zero dollar co-pay to further reduce barriers for patients, so that when healthcare providers want their patients to have neffy, we are able to assist and address potential obstacles.”

Third Quarter 2025 Financial Results

•

Revenue: Total revenue for the third quarter of 2025 was $32.5 million, comprised of $31.3 million in net product revenue from neffy sales in the U.S., and $1.1 million in supply revenue from partners. The cash value of royalties received from ALK-Abelló A/S (ALK) related to the launch of EURneffy® in Germany at the end of June 2025 was $0.1 million, which was recorded to the financing liability on the company’s balance sheet.

•

Research and Development (R&D) Expenses: R&D expenses for the third quarter of 2025 were $2.8 million, which was primarily associated with the ongoing Phase 2b clinical trial in urticaria and 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 third quarter of 2025 were $74.8 million, reflecting the company’s substantial investment in the national DTC marketing campaign and continued sales and marketing expenses associated with the U.S. commercialization of neffy. The company remains committed to continued investment in neffy promotion to further expand patient and physician awareness and to accelerate market share growth.

•

Net Loss: Net loss for the third quarter of 2025 was $51.2 million, or $0.52 per share.

•

Cash Runway: As of September 30, 2025, ARS Pharma had cash, cash equivalents, and short-term investments of $288.2 million, with 98,844,178 shares of common stock outstanding. This includes the $100 million draw down from the company’s new $250 million senior security term loan facility with an affiliate of RA Capital Management, the company’s largest shareholder, and an affiliate of OMERS Life Sciences as lenders. The $100 million draw is intended to fund investment in the commercial growth of neffy, and support our marketing and medical affairs initiatives to generate and disseminate real-world evidence about neffy’s effectiveness. The company believes that its quarter-end cash position will fund operations through expected cash-flow breakeven.

neffy Commercial Launch Progress in the United States

•

DTC campaign growing awareness: The DTC campaign has significantly increased consumer awareness of neffy since its launch late in the second quarter of 2025, growing from a baseline consumer awareness of approximately 20% pre-campaign to 56% as of September 2025.

•

Gross-to-net retention of at least 50%: Unrestricted payor access is expected to be achieved while maintaining steady-state gross-to-net retention guidance of at least 50% including co-pay support programs, where it is anticipated to remain long-term.

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

•

Increasing breadth and depth of healthcare provider (HCP) adoption: Over 18,000 HCPs have prescribed neffy to date, representing an 86% increase from August 2025.

•

“Get neffy on Us” campaign launched: The company initiated a new integrated commercial program to eliminate the time burden of an office visit and reduce cost barriers by giving patients with a current epinephrine autoinjector prescription or diagnosis the opportunity to switch to neffy via a free virtual provider at a $0 co-pay. Consumer surveys indicate that more than 70% of Type I allergy patients are open to using a virtual prescribing option.

•

Allergist real-world experience supports similar treatment outcomes as injection: An updated analysis of real-world treatment outcomes with 680 patients was presented as an oral late-breaker at the American College of Asthma, Allergy and Immunology (ACAAI) in early November 2025. The data showed about 90% of patients experiencing anaphylaxis were effectively treated with a single dose of neffy, and that this real-world effectiveness of neffy is indistinguishable from historically reported epinephrine injection. The neffy Experience Program provides 2 mg and 1 mg neffy to allergists for in-office use during an anaphylaxis event occurring during oral food challenges or allergen immunotherapy.

•

School access expansion: More than 6,500 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.

Global Expansion for neffy and EURneffy

•

neffy approval in Japan: In September 2025, the Pharmaceutical and Medical Devices Agency (PMDA) granted approval for neffy 2 mg and 1 mg in Japan for the emergency treatment of allergic reactions (anaphylaxis) in adults and children who weigh greater than 15 kg. Alfresa owns the rights to market neffy in Japan and expects neffy to be available in the fourth quarter of 2025. Under the terms of the agreement, following listing of neffy on the Japanese National Health Institute (NHI) Drug Price List, ARS Pharma is eligible to receive a final regulatory milestone payment of $2 million, and to sell neffy to Alfresa at a transfer price.

•

EURneffy® launch in United Kingdom (U.K.): ALK successfully launched EURneffy® 2 mg in the U.K. in October 2025. The United Kingdom is the largest market outside of the United States for adrenaline (epinephrine) auto-injector sales.

•

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) is expected in the first quarter of 2026, with launch expected to start 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 ongoing: A Phase 2b trial (NCT06927999) to evaluate intranasal epinephrine technology as a treatment for acute flares is enrolling patients with chronic spontaneous urticaria in the U.S. and Europe, with topline data anticipated in mid-2026.

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.
