During the three months ended December 31, 2024, none of our directors or officers adopted orterminated a “Rule 10b5-1 trading arrangement” or “non-Rule 10b5-1 trading arrangement,” as each term is defined in Item 408(a) of Regulation S-K.

On March 4, 2025, the Board of Directors of the Company, or the Board, appointed Richard J. Statuto to serve as a director of the Company, effective as of immediately following the filing of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024, to hold office for a term expiring at the 2025 Annual Meeting of Stockholders, or the 2025 Annual Meeting, and until a successor is duly elected and qualified or until Mr. Statuto’s earlier death, resignation, or removal. Mr. Statuto has also been appointed as a member of the Audit Committee and Management Development and Compensation Committee of the Board.

Also, on March 6, 2025, Eric “Ric” C. Andersen and William G. Robinson, Jr. each informed the Company that they will not stand for re-election to the Board at the 2025 Annual Meeting. Mr. Andersen’s and Mr. Robinson’s terms will therefore expire at the conclusion of the 2025 Annual Meeting. The Board intends to reduce the size of the Board effective as of that time, rather than filling the resulting vacancies.
