SUPPLEMENTAL INFORMATION TO THE PROXY STATEMENT FOR THE

DOMINION ENERGY, INC.

2025 ANNUAL MEETING OF SHAREHOLDERS

TO BE HELD ON WEDNESDAY, MAY 7, 2025

This Supplemental Information to the Proxy Statement, dated April 8, 2025 (this Supplement), supplements the Definitive Proxy Statement of Dominion Energy, Inc. (the Company) filed with the Securities and Exchange Commission (the SEC) on March 28, 2025 (the Proxy Statement), relating to the 2025 Annual Meeting of Shareholders of the Company (the Annual Meeting) to be held on Wednesday, May 7, 2025 at 9:30 a.m. Eastern Time, exclusively online via webcast at www.virtualshareholdermeeting.com/D2025.

The purpose of this Supplement is to correct an error in the beneficial ownership table included on page 84 of the Proxy Statement under the heading “Security Ownership of Certain Beneficial Owners and Management – Beneficial Ownership as of March 14, 2025” with respect to the number of shares of the Company’s common stock beneficially owned by Susan N. Story. The number of shares of the Company’s common stock beneficially owned by Ms. Story was inadvertently omitted from the version of the Proxy Statement filed on EDGAR due to a technical error. The printed version of the Proxy Statement mailed to shareholders and the courtesy PDF copy provided to the SEC on March 28, 2025 with the EDGAR filing included the correct information with respect to the number of shares of the Company’s common stock beneficially owned by Ms. Story.

Accordingly, the Proxy Statement disclosure under the heading “Security Ownership of Certain Beneficial Owners and Management – Beneficial Ownership as of March 14, 2025” is amended and replaced in its entirety with the revised version provided on the following page. This Supplement does not change the proposals to be acted upon at the Annual Meeting, which are described in the Proxy Statement. Except for the information in this Supplement regarding the disclosure under the heading “Security Ownership of Certain Beneficial Owners and Management – Beneficial Ownership as of March 14, 2025,” all information set forth in the Proxy Statement remains unchanged.
