**Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.**

On June 16, 2025, Daniel N. Swisher, Jr., chair of the board of directors (the "Board") of Cerus Corporation (the "Company"), notified the Company of his intent to retire from the Board and all committees thereof on which he served, effective immediately. Mr. Swisher's decision to retire from the Board was not because of a disagreement with the Company on any matter relating to the Company's operations, policies or practices.

In connection with Mr. Swisher's retirement, on June 20, 2025, the Board appointed William M. Greenman, the Company's President and Chief Executive Officer and a member of the class of directors whose terms of office expire at the Company's 2026 annual meeting of stockholders, to serve as chair of the Board and Frank Witney, Ph.D., a member of the class of directors whose terms of office expire at the Company's 2027 annual meeting of stockholders, to serve as the Board's lead independent director, in each case effective immediately.
