Commercial Opportunity and Strategy

MULTIPLE LEVERS OF CURRENT MARKET GROWTH Significant existing US market opportunity for neffy penetration CURRENT ~$1 BILLION1 ANNUAL EPINEPHRINE MARKET IS THE IMMEDIATE OPPORTUNITY 1 SEC filings, IQVIA data and ARS payer research data on file 2 ARS market research data on file (n = 75 physicians, n = 150 patients), 3 IQVIA extended unit data ~3.3M Patients have injectable today (~10 million devices)3 ~16M diagnosed and HCP-managed patients with severe type I allergic reactions (claims data) Consistent market growth +5% y/y in the last ~15 years Promotional responsiveness +31% historic lift from Mylan No meaningful promotion today More devices per patient Potential for twice as many neffy devices annually vs. injectables ~2.5M Former patients discontinued or did not fill Rx in last 3 years Up to 40M total type I allergy patients (epidemiology)

Physicians supportive of adopting neffy into practice Would prescribe neffy if their patients asked for it 100% 10 = MAJOR ADVANCE / 1 = NOT AN ADVANCE AT ALL 8.5 out of 10 rating viewed as a major advance in therapy n = 75 Physicians No difference in uptake of neffy by physician specialty

neffy addresses the unmet need and is better aligned with what healthcare providers, patients and parents want 65% to 72% OF THE TIME, PEOPLE WHO USE AN OTC WOULD USE neffy FIRST 69% OF PEOPLE WOULD USE neffy SOONER THAN CURRENT AUTOINJECTOR OF NON-FILLING PATIENTS STATED THEY WOULD ASK THEIR PHYSICIAN ABOUT neffy RX 75% n = 150 Current Users OF PATIENTS EXPECTED TO SWITCH TO neffy ~80% n = 100 Non-fillers

Caregivers are enthusiastic about neffy and its benefits Source: ARS Consumer Quant Research, 2022 This is fantastic. Much easier than jabbing the thigh. – Father We are talking about someone’s life and lifestyle here. Great improvement. – Mother I don’t have a co-pay, but I’d get this for my daughters even if I have to pay $50. – Mother I want this. Is it available yet? Let me know when it is, I will literally call the doctor from my car. – Mother “ “ “ “ Guidelines recommend immediate treatment with epinephrine. Earlier administration is associated with improved clinical outcomes and decreased likelihood of hospitalizations.

Payer research supports positive reimbursement environment Key findings from discussions with ~50 decision-makers within the major payers and PBMs: Category is generally not restricted, unlike biologics and orphan disease drugs with high WACs Payers view neffy as a valuable and differentiated treatment option High likelihood of attaining favorable coverage (Tier 2 or 3) for ~80% of lives “This is a game-changer; it really addresses the unmet needs we currently have in this space, specifically the safety and tolerability issues.” – Payer “If this is priced properly, this could be a ‘state-of-the-art therapy’ for patients.” – PBM “Nasal delivery will overcome some negative perceived factors of an injection.” – Payer “There is no value in delaying access to a product like this and nothing to prior authorize (PA). We can’t PA if the patient needs it.” – PBM

Commercial strategy and imperatives Ensure broad and rapid neffy coverage as well as affordable access for patients Change HCP habits and switch prescribing from needle to neffy Drive neffy awareness and new patient growth (into and back into) the market 3 1 2 From needle to neffy: Convert the existing market Bring back patients that are lapsed Bring in patients who should be carrying epinephrine now, but do not carry

Drive neffy awareness and new patient growth (into and back into) the market Ensure broad and rapid neffy coverage as well as affordable access for patients Strategic Imperatives and CSFs: From Needle to neffy Change HCP habits and switch prescribing from needle to neffy 1 2 3 Payers recognize the value proposition of neffy Patients can access neffy Prescriptions are filled seamlessly HCP awareness at launch Confidence in neffy and intranasal delivery Allergists and KOL endorsement Consumer awareness of neffy Patient understanding of effectiveness and safety Patients will ask for neffy proactively CRITICAL SUCCESS FACTORS STRATEGIC IMPERATIVES

Integrated HCP Promotion to Drive Awareness and Reach with Current Epinephrine Prescribers Representing >40% of Prescriptions* Specialty Salesforce Virtual Salesforce Non-Personal Promotion FTEs ~125 FTEs 40 - 50 Top 50,000 Decile 5 to 10 HCP Reach ~ 15,000 HCPs ~3,000 Top 12,000 HCP promotion will be supported by DTC promotion to drive expansion within the addressable SAR market * Reaching >80% of Prescriptions from Allergists, ENTs, and Pediatricians

neffy is positioned potentially to transform the treatment of serious allergic reactions Less Hesitation to Dose Effective Compact Safe Easy to Use No Needle PK superior to IM (Reference listed drug & gold standard) offers therapeutic exposures and makes it easy to switch No meaningful side effects No needle-related injuries possible No serious safety risks associated with injection devices (needle) No blood vessel injections, no lacerations, no bone injections No needle, no fear, no wait Easier to use and more reliable delivery than with autoinjectors (less chance of failed dosing) Always available with child, parent and caregiver 100% of adults (N=105) successfully dosed in human factors studies

Many patients/caregivers do not administer treatment or delay use during reaction Did not fill or re-fill their Rx in last 3 years1 ~50% do not carry2 Patients (millions) Rx’ed Epinephrine in Last 3 Years1 40-60% delay 9 to 18 min6 25-50% refuse to inject and go to ER2-5 23-35% fail to dose correctly7 ~10%-20% of patients receiving Rx treat as indicated (~2% of overall population) 1.
