Audit Committee Charter


(Amended and Restated as of December 16, 2021)

I. General Focus

The Audit Committee (the “Committee”) shall provide assistance to the Duke Energy Corporation (the “Corporation”) Board of Directors (“Board”) in fulfilling its responsibilities with respect to its oversight of the quality and integrity of the Corporation’s financial statements; the Corporation’s compliance with legal and regulatory requirements; the independent auditor’s qualifications and independence; the performance of the Corporation’s internal audit function and independent auditors; and the implementation and effectiveness of the Corporation’s ethics and compliance program.

II. Structure and Operations

The Committee shall be comprised of three or more members of the Board, each of whom is determined by the Board to be “independent” under the rules of the New York Stock Exchange, Inc. (“NYSE”) and the rules promulgated by the Securities and Exchange Commission (“SEC”) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

Each member of the Committee shall have a working familiarity with basic finance and accounting practices (or acquire such familiarity within a reasonable period after his or her appointment) and at least one member shall in the judgment of the Board of Directors have accounting or related financial management expertise as required by the rules of the NYSE.

Each member of the Committee shall be appointed by the Board and shall serve until such member’s successor is duly elected and qualified or until such member’s earlier resignation or removal. The members of the Committee may be removed, with or without cause, by majority vote of the Board.

The Board shall elect the Chair of the Committee. The Chair will approve the agendas for Committee meetings and any member may suggest items for consideration. Briefing materials will be provided to the Committee as far in advance of meetings as practicable.

III. Meetings

The Committee shall meet as frequently as circumstances dictate. Each regularly scheduled meeting will conclude with an executive session of the Committee absent the members of management. The Chair of the Committee or a majority of the members of the Committee may call a special meeting of the Committee. As part of its goal to foster open communication, the Committee shall periodically meet separately with each of management, the personnel responsible for the internal audit function and the independent auditors to discuss any matters that the Committee or each of these groups believe should be discussed privately. The Committee may meet privately with the chief legal officer and the personnel responsible for the ethics and compliance program, as necessary.

All non-management directors who are not members of the Committee may attend meetings of the Committee but may not vote. Additionally, the Committee may invite to its meetings any director, member(s) of management of the Corporation and such other persons as it deems appropriate in order to carry out its responsibilities. The Committee may also exclude from its meetings any person it deems appropriate in order to carry out its responsibilities.

A majority of the members, but not less than two, will constitute a quorum. A majority of the members present at any meeting at which a quorum is present may act on behalf of the Committee. The Committee may meet by telephone or videoconference and may take action by unanimous written consent.

The Committee shall appoint a person who need not be a member thereof to act as secretary and minutes of its proceedings shall be kept in minute books provided for that purpose. The agenda of each meeting will be prepared by the secretary and, whenever reasonably practicable, circulated to each member prior to each meeting.

IV. Responsibilities and Duties

The following functions shall be the common recurring activities of the Committee in carrying out its responsibilities outlined in Section I of this Charter. These functions should serve as a guide with the understanding that the Committee may carry out additional functions and adopt additional policies and procedures as may be appropriate in light of changing business, legislative, regulatory, legal or other conditions. The Committee shall also carry out any other responsibilities and duties delegated to it by the Board of Directors from time to time related to the purposes of the Committee outlined in Section I of this Charter.

The Committee, in discharging its oversight role, is empowered to study or investigate any matter of interest or concern that the Committee deems appropriate. In this regard, the Committee shall have the authority to retain outside legal, accounting or other advisors for this purpose, including the authority to approve the fees payable to such advisors and any other terms of retention.

The Committee shall be given full access to the Corporation’s internal audit group, ethics and compliance personnel, Board, corporate executives and independent accountants, as necessary, to carry out these responsibilities. While acting within the scope of its stated purpose, the Committee shall have all the authority of the Board.

Notwithstanding the foregoing, the Committee is not responsible for certifying the Corporation’s financial statements or guaranteeing the independent auditor’s report. The fundamental responsibility for the Corporation’s financial statements and disclosures rests with management and the independent auditors.
