SAN DIEGO, May 14, 2025 – ARS Pharmaceuticals, Inc. (Nasdaq: SPRY), a biopharmaceutical company dedicated to empowering at-risk patients and caregivers to better protect patients from allergic reactions that could lead to anaphylaxis, today announced financial results for the first quarter of 2025 and provided an update on the continued U.S. 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.

First Quarter 2025 Financial Results

neffy Commercial Launch Progress in the United States

“We’ve built strong momentum for neffy’s U.S. launch and are well positioned heading into the peak epinephrine prescribing season this summer,” said Richard Lowenthal, Co-Founder, President and CEO of ARS Pharma. “Children represent almost half of the prescriptions for epinephrine, underscoring the critical need for a needle-free, easy-to-use, easy-to-carry epinephrine option. We’ve had solid wins in market access, and the accelerated sales force expansion with our ALK partnership expands our reach to key pediatricians ahead of summer travel and the back-to-school season. Coupled with compelling clinical data and enhanced real-world adoption, we believe neffy is positioned to become the standard of care for those at risk of severe allergic reactions and a leading treatment option in the category.”

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

“Our efforts to scale the commercial footprint of neffy has been very encouraging,” added Eric Karas, Chief Commercial Officer, ARS Pharma. “Demand for neffy continues to grow among both patients and physicians, with thousands of healthcare professionals prescribing neffy already, and thousands more participating in our neffyExperience program. Our national DTC campaign is set to launch on May 15th, and we expect to generate strong brand awareness driving patients and caregivers to request neffy from their healthcare provider over the coming months. In parallel, coverage wins with major pharmacy benefit managers ensures more patients and prescribers will be able to seamlessly access neffy this summer. These milestones, coupled with the positive feedback we continue to hear from those who have used neffy, underscore its value and support our goal of establishing neffy as a category-defining brand in emergency allergy care.”

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 ww.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.
