Departure of Directors or Certain Officers

On August 11, 2026, Rajendra (“Raj”) Khanna, a member of the Board, notified the Company that he will not stand for reelection to the Board at the Company’s Annual Meeting of Stockholders to be held on November 4, 2026 (the “Annual Meeting”). Mr. Khanna will continue to serve as a director until the Annual Meeting.

Mr. Khanna has confirmed that his decision not to stand for reelection is not the result of any disagreement with the Company on any matter relating to the Company’s operations, policies, or practices.
