On June 18, 2026, Vishwas Setia was separated as the Chief Financial Officer of MapLight Therapeutics, Inc. (the "Company"), effective immediately, following a review of a human resources violation.

Mr. Setia is not entitled to receive any severance payment in connection with his separation. However, the Company and Mr. Setia entered into a Separation Agreement on June 18, 2026, which contains (i) a release of claims against the Company and (ii) payment of continued health coverage for Mr. Setia and his dependents under COBRA for up to three months.

The description of the Separation Agreement provided herein is not complete and is qualified in its entirety by reference to the Separation Agreement, which the Company intends to file as an exhibit to its Quarterly Report on Form 10-Q for the quarter ending June 30, 2026.

In connection with the separation of Mr. Setia, the board of directors of the Company appointed Jonathan Gillis, the Company's Chief Administrative and Accounting Officer, as the Company's interim Chief Financial Officer and interim principal financial officer, effective June 18, 2026. Mr. Gillis will also continue his role as the Company's principal accounting officer.
