Explanation of Responses:

1. Effective as of a pro rata distribution by AnaptysBio to holders of its shares of common stock pursuant to the Separation and Distribution Agreement dated as of April 20, 2026, by and between AnaptysBio and First Tracks (the "Separation Agreement"), each outstanding option to acquire AnaptysBio shares of common stock was adjusted so that such option became an option to acquire First Tracks shares of common stock and an option to acquire AnaptysBio shares of common stock. As a result, the Reporting Person acquired options to acquire AnaptyBio shares of common stock in an amount determined in accordance with the Separation Agreement.

2. The stock option is fully vested and exercisable.

3. The stock option vests as to 1/12 of the total shares monthly commencing on February 6, 2026 until fully vested, subject to the Reporting Person's provision of service to the Issuer on each vesting date.
