Audit Committee Charter

ON April 28, 2021


The Audit Committee (the “Committee”) is appointed by the Board of Directors (the “Board”) of McKesson Corporation (the “Company”) to assist the Board in monitoring:

  1. The integrity of the financial statements of the Company.
  2. The independent auditors' qualifications, independence and performance.
  3. The performance of the Company's internal audit function.
  4. The compliance by the Company with legal and regulatory requirements.

The Committee shall prepare the report required by the rules of the Securities and Exchange Commission (the “Commission”) to be included in the Company’s annual proxy statement.


The Committee shall consist of no fewer than three members. The members of the Committee shall meet the independence and experience requirements of the New York Stock Exchange (“NYSE”), Section 10A(m)(3) of the Securities Exchange Act of 1934 (the “Exchange Act”) and the rules and regulations of the Commission (taken together, the “Applicable Rules”). All members of the Committee shall comply with all financial-literacy requirements of the NYSE. The Company shall disclose as required by the Commission whether at least one member of the Committee is an “audit committee financial expert” as defined by the Commission. The simultaneous service on the audit committees of more than two other public companies requires a Board determination that such simultaneous service does not impair the ability of such member to serve effectively on the Company’s Audit Committee.

The members of the Committee shall be appointed, or may be replaced, by the Board.


The Committee may fix its own rules of procedure, which shall be consistent with the By-Laws of the Company and this Charter. The Committee shall meet as often as it determines, but not less frequently than quarterly, and at least once annually, the Committee shall meet jointly with the Compliance Committee. The Board may designate one member of the Committee as its Chairperson and in the absence of any such designation by the Board, the Committee shall designate by majority vote of the full Committee one member of the Committee as its Chairperson. The Committee shall meet periodically with management, the internal auditor and the independent auditors in separate executive sessions, and also in executive session with only the Committee members.

The Committee may request that any directors, officers or employees of the Company, or other persons whose advice and counsel are sought by the Committee, attend any meeting of the Committee to provide such pertinent information as the Committee requests, or to meet with any members of, or advisors to, the Committee.

Following each of its meetings, the Committee shall deliver a report on the meeting to the Board, including a summary description of actions taken by the Committee at the meeting. The Committee shall keep written minutes of its meetings, which minutes shall be maintained with the books and records of the Company.

The Committee shall review and reassess the adequacy of this Charter annually and recommend any proposed changes to the Board for approval. The Committee shall annually conduct a self-assessment and report the results to the Board.


The Committee shall have the sole authority to appoint, retain, compensate, evaluate and terminate the independent auditors. The Committee shall be directly responsible for the compensation and oversight of the work of the independent auditors (including resolution of disagreements between management and the independent auditors regarding financial reporting) for the purpose of preparing or issuing an audit report or related work. The independent auditors shall report directly to the Committee.

The Committee shall preapprove all auditing services and permitted non-audit services (including the fees and terms thereof) to be performed for the Company by its independent auditors, subject to the de minimis exceptions for non-audit services described in Section 10A(i)(1)(B) of the Exchange Act, which should be approved by the Committee prior to the completion of the audit. In connection with such approvals, the Committee may form and delegate authority to subcommittees consisting of one or more members when appropriate, including the authority to grant preapprovals of audit and permitted non-audit services, provided that decisions of such subcommittee to grant preapprovals shall be presented to the full Committee at a subsequent meeting.

The Committee shall have the authority, to the extent it deems necessary or appropriate, to retain independent legal, accounting or other advisors. The Company shall provide for appropriate funding, as determined by the Committee, for payment of compensation to the independent auditors for the purpose of preparing or issuing an audit report and to any advisors employed by the Committee.

The Committee, to the extent it deems necessary or appropriate or as required by the Applicable Rules, shall:

As to Financial Statement and Disclosure Matters

  15. Evaluate the qualifications, performance and independence of the independent auditors, including considering whether the auditors’ quality controls are adequate and whether the provision of any permitted non-audit services is compatible with maintaining the auditors’ independence, and taking into account the opinions of management and internal auditors.

  25. As required by applicable law, review at least annually the report prepared by management, and attested to by the independent auditors, assessing the effectiveness of the Company’s internal control structure and procedures for financial reporting and stating management’s responsibility to establish and maintain such structure and procedures, prior to its inclusion in the Company’s annual report.
