Sebulsky to the Board as a Class I director, effective September 23, 2026, with a term that expires at the Company’s 2028 annual meeting of shareholders when Class I directors are up for re-election and until his successor is duly elected and qualified. Mr. Sebulsky has been appointed to serve as a member of the Science and Technology Committee. Mr. Sebulsky was recommended as a potential candidate for election to our Board by the Company’s senior management.

Mr. Sebulsky has served as the Managing Member of Apothecary Capital LLC since its reestablishment in April 2026. Mr. Sebulsky previously served as a Partner and Portfolio Manager at Adage Capital Management, LP. from July 2012 to April 2026, where he was responsible for managing a biopharmaceutical portfolio.

Mr. Sebulsky received a B.B.A. in finance and economics and an M.S. in finance from the University of Wisconsin, Madison.

Mr. Sebulsky will be eligible to receive compensation for his service as a member of the Board pursuant to the terms of the Company’s Non-Employee Director Compensation Program, as amended from time to time.
