Potential to Transform the Treatment of Type I Allergic Reactions neffy®: first potential “no needle, no injection” solution for Type I allergic reactions to address an unmet market need Registration program demonstrates comparable PK and PD, without risk of needle-related safety concerns, fear and hesitation Rapid and statistically significant response on PD surrogates for efficacy (SBP, HR) observed even 1 minute after dosing with neffy vs. injection Significant opportunity to disrupt current epinephrine injectables market FDA AdCom supports favorable benefit-risk assessment, but FDA requested one additional study (twice-dosing nasal challenge study) Anticipated NDA resubmission in H1 2024, with FDA action in H2 2024 Potential multi-billion-dollar market driven by HCP and consumer preference and adoption NCE-like IP exclusivity potential until at least 2038 $252 million in cash and securities as of 6/30/2023 with an anticipated $195 million in cash and securities at anticipated FDA action in H2 2024

Rapid administration without a needle No risk of needle-related injuries; lacerations2 or cardiotoxic blood vessel injections Less hesitation to dose NO NEEDLE NO INJECTION SMALL Fits in your pocket; can carry more than 1 ~10% of cases require multiple doses of epinephrine1 EASIER AND MORE CONSISTENT DOSING 0% critical dosing errors in registration self-administration study Low 2 mg dose of neffy achieves comparable PK without overexposure risk RELIABLE 99.999% delivery of effective dose in reliability testing; no inhalation required 24 month shelf-life at room temperature, with up to 3 months at high temperatures (122oF) ~50% of patients carry1 (<20% carry two) ~25% - 60%1, 3, 5, 6 do not administer PROBLEM ONLY 10% - 20% of patients with active Rx use as indicated7 1.

neffy Designed for Needle-free, Easier Carriage

Registrational studies demonstrate comparability on both PD surrogates for efficacy and PK with neffy Safety Data 2 mg neffy met all clinical endpoints PD surrogates for efficacy comparable to approved products (SBP/HR approved injection products) Rapid and significant response on PD surrogates for efficacy observed even 1 minute after dosing PK bracketed by approved products (exposures IM/SC for efficacy, < EpiPen for safety)   Adverse events generally mild in nature with no meaningful nasal irritation or pain up to 4 mg dose Most common adverse events (>5%) were mild nasal discomfort (9.7%) and mild headache (6%), with no correlation of nasal discomfort to pain or irritation Mean VAS pain scores between 5 to 8 out of 100 No irritation based on formal assessment No serious adverse events in any clinical study No risk of needle-related injuries or blood vessel injections with neffy PD and PK Data

FDA Complete Response Letter requests nasal allergen challenge (NAC) study with repeat doses of neffy Mean Plasma Concentration (pg/mL) Time (mins) Repeat-dosing (10 min apart) results in healthy subjects neffy with repeat dosing is dose-proportional, whereas the approved injection products are not, and therefore overall exposure of neffy is higher FDA requested additional study to confirm that neffy’s repeat dose PK profile is at least comparable to repeat doses of injection under nasal allergen challenge conditions NDA resubmission expected in 1H 2024 with FDA action expected in 2H 2024
