Explanation of responses
- F1On September 18, 2025, the Issuer effected a 1-for-20 reverse stock split. The exercise price and number of shares underlying the stock option give effect to the reverse stock split.
- F2RA Capital Management, L.P. (the "Adviser") is the investment manager for RA Capital Healthcare Fund, L.P. (the "Fund"). The general partner of the Adviser is RA Capital Management GP, LLC (the "Adviser GP"), of which Dr. Peter Kolchinsky and Mr. Rajeev Shah are the managing members. Each of the Adviser, the Adviser GP, the Fund, Dr. Kolchinsky and Mr. Shah disclaims beneficial ownership of any of the reported securities, except to the extent of its or his respective pecuniary interest therein.
- F3This option was granted to Joshua Resnick pursuant to the Issuer's non-employee director compensation policy. Under Mr. Resnick's arrangement with the Adviser, Mr. Resnick held the option for the benefit of the Fund. Mr. Resnick is obligated to turn over to the Adviser any stock received upon exercise of the option, which will offset advisory fees owed by the Fund to the Adviser. The Reporting Persons therefore disclaim beneficial ownership of the option and underlying common stock.
