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

On April 13, 2026, Luther C. Kissam, IV, a member of the Board of Directors (the "Board") of OGE Energy Corp. (the "Company"), informed the Company that he will not stand for re-election at the end of his term and will resign from the Board at the upcoming annual shareholder meeting scheduled for May 14, 2026 (the "Annual Meeting"). His resignation will be effective on that date. Mr. Kissam has served for more than five years on the Board and various Board committees. Mr. Kissam stated that his decision is based on recently accepting a new position as chief executive officer of another company, which requires him to resign as a member of the board of directors of other companies. His decision is not due to any disagreement with the Company on any matter relating to the Company's operations, policies, or practices. We wish Mr. Kissam continued success in the future.

Mr. Kissam had been included as a nominee of the Board in the Company's definitive proxy statement and proxy card for the Company's Annual Meeting. In light of his departure from the Board, Mr. Kissam is no longer standing for re-election to the Board at the Annual Meeting, and the Company's proxy materials are hereby deemed amended to remove Mr. Kissam as a nominee for the Annual Meeting. Effective as of the date of the Annual Meeting, the number of directors on the Board will be reduced to eight directors, but otherwise, the Company's slate of nominees remains unchanged. Previously voted proxies remain valid, other than with respect to Mr. Kissam as he is no longer standing for re-election.
