On May 12, 2026, the Board of Directors of ARS Pharmaceuticals, Inc., a Delaware corporation (the “Company”), based in part on the recommendation of Richard Lowenthal, the Company’s Chief Executive Officer, appointed Donn Casale as the Company’s President effective as of the date he commences employment with the Company, which date is expected to be June 1, 2026. Mr. Lowenthal previously served as President.

Mr. Casale, age 53, has over 25 years of experience in the biopharmaceutical industry. Mr. Casale previously worked at Dynavax Technologies, Inc. (acquired by Sanofi in 2026) from October 2017 to May 2026 in roles of increasing responsibility, most recently serving as Chief Commercial Officer since January 2023. Prior to joining Dynavax Technologies, Inc., Mr. Casale worked at Depomed, Inc. from March 2014 to October 2017, most recently serving as Director, Marketing. Mr. Casale started his career at Merck & Co., Inc., where he served in various positions from January 2000 to March 2014. Mr. Casale holds a bachelor’s degree in political science from the California Polytechnic State University – San Luis Obispo.

In connection with his anticipated employment with the Company and appointment as the Company’s President, the Company entered into an employment agreement with Mr. Casale (the “Employment Agreement”), which sets forth the terms of Mr. Casale’s employment with the Company. Pursuant to the Employment Agreement, Mr. Casale will be entitled to receive an annual base salary of $575,000 and will be eligible to earn an annual discretionary bonus of 45% of his then-current annual base salary. In addition, pursuant to the Employment Agreement, the Company will grant Mr. Casale a stock option under the Company’s 2020 Equity Incentive Plan to purchase the number of shares of the Company’s common stock determined by dividing $6,000,000 by a price per share determined based on a modified Black-Scholes methodology. The exercise price of each share of the Company’s common stock underlying the option will be the Grant Date Closing Price. Twenty-five percent of the option will vest after one year, and the balance will vest monthly over the following 36 months, provided Mr. Casale remains employed with the Company on each respective vesting date.

In addition to the Employment Agreement, Mr. Casale will enter into a participation agreement to the Company’s Change in Control and Severance Benefit Plan (the “Participation Agreement”) in substantially the form previously filed as Exhibit 10.8 to the Company’s Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission (“SEC”) on March 23, 2023. Pursuant to the Participation Agreement, Mr. Casale will have the right to receive the severance and change in control benefits provided to C-Suite level officers (other than the Chief Executive Officer) under the Company’s Change in Control and Severance Benefit Plan; provided that the accelerated vesting of the above-described option will be limited to the extent Mr. Casale’s employment is terminated in connection with a change in control transaction during the initial year of his employment.

The foregoing summary of the Employment Agreement is not complete and is qualified in its entirety by reference to the full agreement, a copy of which is filed as Exhibit 10.1 to this report.

The Company and Mr. Casale will also enter into the Company’s standard indemnification agreement for the Company’s directors and officers, a copy of which is filed as Exhibit 10.1 to the Company’s Registration Statement on Form S-1, filed with the SEC on November 10, 2020.
