#### Board Meetings and Committees
During 2024, our Board met six times, and each Board member attended 75% or more of the total number of meetings of the Board and of the committees on which he or she served. In addition, our Board met in executive session without management present during its four regularly scheduled meetings in 2024. Our chairman of the Board presides over the executive sessions of the Board, and our lead independent director presides over the independent director sessions of the Board.

We encourage our directors to attend our annual meetings of stockholders, and all of our directors attended our 2024 annual meeting of stockholders.

The Board has established three principal Board committees: the Audit Committee, the Nominating and Corporate Governance Committee, and the Talent and Compensation Committee. In June 2017, the Board established a fourth Board committee, the Cybersecurity Committee, and in June 2018, the Board established a fifth Board committee, the Strategic Committee. The memberships of all five Board committees in 2024 were composed entirely of independent directors.
