Item 5.03. Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

On December 12, 2025, the Board of Directors (the “Board”) of CareDx, Inc. (the “Company”) amended and restated the Company’s bylaws (the “Amended and Restated Bylaws”) to change the voting standard for the election of directors from a plurality to a majority voting standard, except in a contested election, where a plurality vote shall apply. Under the new majority voting standard, a nominee for director shall be elected to the Board only upon the affirmative vote of at least a majority of the votes cast, which means that the number of votes “for” a nominee exceeds the votes cast “against” that director’s election with abstentions and broker non-votes, if applicable, not counted as votes cast with respect to a director’s election.

In addition, the Board also approved a director resignation policy pursuant to which any incumbent director who does not receive at least a majority of the votes cast in an uncontested election shall be required to promptly submit their resignation to the Board for consideration by the Governance and Nominating Committee of the Board (the “Committee”). Within 90 days following certification of the election results, the Board will review and act on the Committee’s recommendation and publicly disclose its decision regarding the tendered resignation.

The foregoing description of the Amended and Restated Bylaws is qualified in its entirety by reference to the text of the Amended and Restated Bylaws, filed as Exhibit 3.2 to this report and incorporated herein by reference.
