On May 23, 2026, Ms. Simantov notified Tempest Therapeutics, Inc. (the “Company”) of her resignation from the Board of Directors of the Company (the “Board”), effective as of such date.

In connection with the transition, the Company and Ms. Simantov entered into a Separation Agreement (the “Separation Agreement”).

The foregoing descriptions of the non-employee director compensation program and Separation Agreement do not purport to be complete and are qualified by reference to the full text of each agreement, copies of which will be filed as exhibits to the Company’s Quarterly Report on Form 10-Q for the quarter ended June 30, 2026.
