On May 26, 2026, Jeffrey T. Elliott, a member of the Board of Directors (the “Board”) of Sera Prognostics, Inc. (the “Company”), notified the Company of his decision to resign from the Board effective as of June 4, 2026, the date of the Company’s Annual Stockholders Meeting (“Annual Meeting”). Mr. Elliott’s resignation was not as a result of any disagreement between Mr. Elliott and the Company on any matter relating to the Company’s operations, policies or practices. Mr. Elliott’s term as a director was scheduled to expire at the Annual Meeting. As a result of this resignation, Mr. Elliott is no longer a director nominee for re-election at the Annual Meeting. In connection with Mr. Elliott’s resignation, the Company’s board of directors (the “Board”) decreased its size to seven directors. Separately, as part of its ongoing focus on strong corporate governance and leadership continuity, the Company is in advanced discussions with highly qualified candidates to join the Board and expects to announce an appointment in the near term.

On June 1, 2026, the Company issued a press release announcing the departure of Mr. Elliott, which is attached hereto as Exhibit 99.1 and incorporated herein by reference.
