 President and CEO at regularly scheduled Board meetings.

Each year, the independent directors of the Board select an independent director to serve as a Lead Director. The Lead Director is expected to consult with the chairs of the appropriate Board committees and solicit their participation. The Lead Director also has the authority to call meetings of the independent directors as well as the non-management directors, and if requested by major shareholders, will ensure that he or she is available for consultation and direct communication. In February 2025, the independent directors of the Board designated Mr. Richard A. Sampson as the Lead Director. Mr. Sampson reached mandatory retirement age in December 2025, so he will not stand for re-election at the 2026 annual meeting of shareholders.

#### Board Committees
Atmos Energy’s Board committee structure is organized around key strategic issues to facilitate oversight of management. Committee Chairs regularly coordinate with one another to ensure appropriate information sharing. To further facilitate information sharing, all committees provide a summary of significant actions to the full Board. As required under our Corporate Governance Guidelines, each standing committee conducts an annual self-evaluation and review of its charter.
