Item 5.07Submission of Matters to a Vote of Security Holders.

The 2026 annual meeting of Valero’s stockholders was held on May 7, 2026. A quorum was present at the annual meeting as required by Valero’s bylaws. Set forth below are the final voting results on the matters voted on at the annual meeting, each of which were also described in Valero’s definitive proxy statement filed with the Securities and Exchange Commission on March 19, 2026 (“Proxy Statement”).

(1)Proposal 1: Election of directors. The election of each director nominee to serve until Valero’s 2027 annual meeting of stockholders was approved as follows:

(2)Proposal 2: Advisory vote to approve the 2025 compensation of Valero’s named executive officers, as described in the Proxy Statement. The proposal was approved as follows:

(3)Proposal 3: Ratify the appointment of KPMG LLP to serve as Valero’s independent registered public accounting firm for the fiscal year ending December 31, 2026. The proposal was approved as follows:

* Notes:

Required votes. For Proposal 1, as required by Valero’s bylaws, each director is to be elected by a majority of votes cast with respect to that director’s election. Any director nominee who does not receive a majority of the votes cast is required to submit an irrevocable resignation to the Board, and the Nominating and Corporate Governance Committee will make a recommendation to the Board as to whether to accept or reject the resignation or take other action. The Board will, within 90 days following certification of the election results, publicly disclose its decision regarding any such resignation and the rationale behind the decision. Proposals 2 and 3 required approval by the affirmative vote of a majority of the voting power of the shares present in person or represented by proxy at the annual meeting and entitled to vote.

Effect of abstentions. Shares voted to abstain are treated as “present” for purposes of determining a quorum. In the election of directors (Proposal 1), pursuant to Valero’s bylaws, shares voted to abstain are not deemed to be “votes cast,” and are accordingly disregarded. When, however, approval for a proposal requires the affirmative vote of a majority of the voting power of the shares present in person or represented by proxy and entitled to vote (Proposals 2 and 3), then shares voted to abstain have the effect of a negative vote.

Effect of broker non-votes. Brokers holding shares for the beneficial owners of such shares must vote according to specific instructions received from the beneficial owners. If instructions are not received, in some instances (e.g., for Proposal 3), a broker may nevertheless vote the shares in the broker’s discretion. Under New York Stock Exchange rules, brokers are precluded from exercising voting discretion on certain proposals without specific instructions from the beneficial owner (Proposals 1 and 2). This results in a “broker non-vote” on the proposal. A broker non-vote is treated as “present” for purposes of determining a quorum, has the effect of a negative vote when approval for a particular proposal requires the affirmative vote of the voting power of the issued and outstanding shares of Valero, and has no effect when approval for a proposal requires the affirmative vote of a majority of the voting power of the shares present in person or represented by proxy and entitled to vote or a plurality or majority of the votes cast.
