The name of this plan is the McKesson Corporation Management Incentive Plan (the “Plan”). This Plan is hereby amended and restated effective as of May 20, 2025.

B.PURPOSE.

The purpose of the Plan is to advance and promote the interests of the Company and its shareholders by providing performance-based incentives to certain employees and to motivate those employees to set and achieve above average financial and non-financial objectives.

C.ADMINISTRATION.

The Committee shall have full power and authority, subject to the provisions of the Plan, (1) to designate employees as Participants for any Performance Period, (2) to add and delete employees, subject to the eligibility requirement set forth in paragraph D.1 below, from the list of designated Participants, (3) to establish Individual Target Awards for Participants, (4) to establish performance goals upon achievement of which the Individual Target Awards will be based, and (5) to take all action in connection with the foregoing or in relation to the Plan as it deems necessary or advisable. Decisions and selections of the Committee shall be made by a majority of its members and, if made pursuant to the provisions of the Plan, shall be final.

The Committee may delegate to the Chief Executive Officer (the “CEO”) the power and authority, subject to the provisions of the Plan, (1) to designate employees who are not members of the Officer Group as Participants, (2) to recommend members of the Officer Group to the Committee for designation as Participants; provided that the Committee shall review and approve members of the Officer Group as Participants recommended by the CEO, (3) to add and delete employees who are not members of the Officer Group, subject to the eligibility requirement set forth in paragraph D.1 below, from the list of designated Participants, (4) to establish Individual Target Awards for Participants who are not members of the Officer Group, (5) to establish performance goals upon achievement of which such Individual Target Awards will be based, and (6) to review and approve, modify or disapprove, or otherwise adjust or determine the amount, if any, to be paid to Participants who are not members of the Officer Group for the applicable Performance Period based on such Participants’ performance goals and individual performance. In addition to the foregoing, the CEO may further delegate their authority to other executive officers of the Company, except that the CEO may not delegate their authority to recommend members of the Officer Group to the Committee for designation as Participants. References to the Committee herein shall include references to the CEO and their designees to the extent that the Committee has delegated power and authority under the Plan to

the CEO and to the extent that the CEO has further delegated power and authority under the Plan to other executive officers of the Company.

The Committee may promulgate such rules and regulations as it deems necessary for the proper administration of the Plan and the CEO (but not their designees) may promulgate rules and regulations as they deem necessary for the proper administration of the Plan with respect to Participants who are not members of the Officer Group. The Committee may interpret the provisions and supervise the administration of the Plan and take all action in connection therewith or in relation to the Plan as it deems necessary or advisable. The interpretation and construction by the Committee of any provision of the Plan or of any award shall be final.

D.PARTICIPATION.

1. Eligibility—Executives, Managers and Professionals

Only an active employee of the Company who is employed in an executive, managerial or professional capacity may be designated as a Participant under the Plan; provided, however, that designation as a Participant is contingent upon the execution and delivery to the Company of an agreement, within a period following presentment and in a form that is satisfactory to the Company, regarding confidentiality, intellectual property and/or other restrictive covenants, as well as compliance with such agreement; and provided, further, that the Committee shall determine in its sole discretion whether the Participant has complied with such agreement, and its determination shall be conclusive and binding on all interested persons.

2. Designation of Participants

No person shall be entitled to any award under the Plan for any Performance Period unless they are designated as a Participant for that Performance Period.

E.INDIVIDUAL TARGET AWARDS FOR PARTICIPANTS.

At the beginning of each Performance Period, the Committee shall establish an Individual Target Award for each Participant. An Individual Target Award shall only be a target, and the amount of the target may or may not be paid to the Participant. Establishment of an Individual Target Award for an employee for any Performance Period shall not imply or require that an Individual Target Award or an Individual Target Award at any specified level will be set for any subsequent year. The amount of any actual award paid to any Participant may be greater or less than this target. As set forth in paragraph G.4 below, the actual award may be as much as three times target or as low as zero for any Performance Period. The Individual Target Award may be established for a Participant by name, job level, position or any other similar identifier.

F.BASIS OF AWARDS.

1. Performance Goals

The Committee shall establish measures, which may include financial and non-financial objectives (“Performance Goals”), in advance of each Performance Period or within 90 days

after the commencement of the Performance Period to which the Performance Goals relate. Performance Goals may be expressed with respect to the Company or one or more operating units or groups, as the Committee may determine. The Committee may determine Performance Goals on an absolute basis or relative to internal goals or relative to levels attained in prior years or related to other companies or indices or as ratios expressing relationships between two or more Performance Goals. In addition, Performance Goals may be based upon the attainment of specified levels of Company performance criteria relative to the performance of other corporations or a designated comparison group. Performance criteria to be used may be any of the following, either alone or in any combination, which may be expressed with respect to the Company or one or more operating units or groups, as the Committee may determine: cash flow; cash flow from operations; total earnings; earnings per share, diluted or basic; earnings per share from continuing operations, diluted or basic; earnings before interest and taxes; earnings before interest, taxes, depreciation, and amortization; earnings from operations; net asset turnover; inventory turnover; capital expenditures; net earnings; operating earnings; gross or operating margin; debt; working capital; return on equity; return on net assets; return on total assets; return on investment; return on capital; return on committed capital; return on invested capital; return on sales; net or gross sales; market share; economic value added; cost of capital; change in assets; expense reduction levels; debt reduction; productivity; stock price; customer satisfaction; employee satisfaction; total shareholder return; average invested capital; credit rating; gross margin; operating expenses; operating expenses as a percentage of revenue; succession plan development and implementation, M&A performance; litigation and regulatory resolution; non-financial priorities as may be determined by the Committee; or any other financial, non-financial, operational, strategic, or individual criteria as may be determined by the Committee.

2. Adjustment Of Performance Goals

The Committee may adjust, and/or may provide in any Performance Goal for the adjustment of, any Performance Goal to the extent necessary to prevent dilution or enlargement of any award as a result of extraordinary events or circumstances, as determined by the Committee, or to exclude the effects of extraordinary, unusual, or nonrecurring items; changes in applicable laws, regulations, or accounting principles; currency fluctuations; discontinued operations; non-cash items, such as amortization, depreciation, or reserves; asset impairment; any recapitalization, restructuring, reorganization, merger, acquisition, divestiture, consolidation, spin off, split up, combination, liquidation, dissolution, sale of assets, or other similar corporate transaction; or any other occurrences or circumstances as the Committee may deem appropriate.

3. Performance Goals Related to More Than One Segment of The Company

Awards may be based on performance against objectives for more than one segment of the Company. For example, awards for corporate management may be based on overall corporate performance against objectives, but awards for a unit’s management may be based on a combination of corporate, unit and sub-unit performance against objectives.

4. Performance Period; Individual Performance

The Committee shall specify the Performance Period over which period Performance Goals will be measured and determined.

Individual performance of each Participant may be measured and used in determining awards under the Plan.

G.AWARD DETERMINATION.

1. Award Determined by Committee

After any Performance Period for which an Individual Target Award is established for a Participant under the Plan, the Committee shall review and approve, modify or disapprove the amount, if any, to be paid to the Participant for the Performance Period. The amount paid shall be the Individual Target Award adjusted to reflect both the results against the Participant’s Performance Goals and the Participant’s individual performance. All awards are subject to adjustment at the sole discretion of the Committee.

2. Financial And Non-Financial Performance

Individual Target Award amounts will be modified based on the achievement of financial and non-financial objectives by the Company and relevant units and/or sub-units. Performance results against objectives shall be reviewed and approved by the Committee.

3. Individual Performance

Any Individual Target Award, adjusted to reflect financial performance, may be further adjusted with the review and approval of the Committee to give full weight to the Participant’s individual performance during the Performance Period.

4. Overall Effect

The combination of any financial performance adjustment and individual performance adjustment may increase the amount paid under the Plan to a Participant for any Performance Period to as much as three times the Individual Target Award and may reduce any amount payable to zero.

H.PAYMENT OF AWARDS.

An award under the Plan shall be paid in a single sum to the Participant as soon as reasonably practicable after Payment Date, unless the Participant elects to defer his or her award pursuant to the terms and conditions of the Company’s Deferred Compensation Administration Plan III (“DCAP III”) and in compliance with Section 409A of the Code. To the extent that an award or a portion thereof is not deferred under DCAP III, such award or portion thereof shall be paid no later than the end of the period under which payment would be deemed to be a “short-term deferral” as defined in the regulations under Section 409A of the Code.

I.EMPLOYMENT ON PAYMENT DATE.

Except as otherwise required by applicable law, no award shall be made to any Participant who is not an active employee of the Company on the Payment Date; provided, however, that the Committee, in its sole and absolute discretion, may make full or prorated awards to Participants in circumstances that the Committee deems appropriate in its discretion, including, but not limited to, a Participant’s death, disability, retirement or other termination of employment prior to the Payment Date. Any such awards shall be determined by the Committee in accordance with Article G above after taking into account the portion of the Performance Period completed. For the avoidance of doubt, no award is earned until payment.

J.CHANGE IN CONTROL.

In the event of a Change in Control, the Company or any successor or surviving corporation shall pay to each Participant an award for the Performance Period in which the Change in Control occurs and for any previous Performance Period for which awards have been earned but not yet paid. Subject to the employment requirements of Article I, each such award shall be equal to the greatest of the following: (1) the Participant’s Individual Target Award for the applicable Performance Period; (2) the Participant’s Individual Target Award for the applicable Performance Period adjusted based on the actual performance outcome for that Performance Period, provided, that the Committee may not invoke its discretionary authority to reduce the amount of such an award; or (3) the average of awards earned and paid to (or deferred by) the Participant in the three (or such fewer number of years that the Participant has been eligible for such an award) completed Performance Periods immediately preceding the applicable Performance Period. Such awards shall be paid by the Company or any successor or surviving corporation at such time as the awards otherwise would be payable under the Plan; provided, however, that if a Participant is terminated without Cause or terminates for Good Reason within twelve months after a Change in Control, then such Participant shall be paid his or her awards determined under this Article J, within thirty days of such termination. Notwithstanding the foregoing, any award determined pursuant to this Article J shall be reduced by any corresponding award payable under a Participant’s individual written employment agreement, if any.

K.FORFEITURE.

Any other provision of the Plan to the contrary notwithstanding, if the Committee determines that a Participant has engaged in criminal activity, fraud, misconduct, embezzlement or any other improper act involving moral turpitude, then upon written notice from the Company to the Participant (1) the Participant shall not be eligible for any award for the year in which such notice is given or for the preceding year, if such award has not been paid as of the date of the notice, (2) any payment of an award received by the Participant within twelve months prior to the date that the Company discovered that the Participant engaged in any action described above shall immediately be repaid to the Company by the Participant in cash (including amounts withheld pursuant to Article L) and (3) any award deferred pursuant to Article H within twelve months prior to the date that the Company discovered that the Participant engaged in any action described above shall be forfeited immediately and shall not be distributed to the Participant under any circumstances. The Committee shall determine in its sole discretion whether the

Participant has engaged in any of the acts set forth above, and its determination shall be conclusive and binding on all interested persons.

Any provision of this Article K which is determined by a court of competent jurisdiction to be invalid or unenforceable should be construed or limited in a manner that is valid and enforceable and that comes closest to the business objectives intended by such invalid or unenforceable provision, without invalidating or rendering unenforceable the remaining provisions of this Article K. The remedy described in this Article K is in addition to and not in lieu of remedies available in law and in equity.

L.RECOUPMENT.

Individual Target Awards, and payments made under such awards, are subject to the McKesson Corporation Compensation Recoupment Policy and the McKesson Corporation Financial Restatement Compensation Recoupment Policy. Such policies are incorporated by reference herein.

M.WITHHOLDING TAXES.

Whenever the payment of an award is made, such payment shall be net of an amount sufficient to satisfy federal, state and local income and employment tax withholding requirements and authorized deductions.

N.EMPLOYMENT RIGHTS.

Neither the Plan nor designation as a Plan Participant shall be deemed to give any individual a right to remain employed by the Company. The Company reserves the right to terminate the employment of any employee at any time, with or without cause or for no cause, subject only to the requirements of a written employment contract (if any).

O.NONASSIGNMENT; PARTICIPANTS ARE GENERAL CREDITORS.

The interest of any Participant under the Plan shall not be assignable either by voluntary or involuntary assignment or by operation of law (except by designation of a beneficiary or beneficiaries to the extent allowed under DCAP III or a successor plan with respect to amounts deferred under Article H) and any attempted assignment shall be null, void and of no effect.

Amounts paid under the Plan shall be paid from the general funds of the Company, and each Participant shall be no more than an unsecured general creditor of the Company with no special or prior right to any assets of the Company for payment of any obligations hereunder. Nothing contained in the Plan shall be deemed to create a trust of any kind for the benefit of any Participant or create any fiduciary relationship between the Company and any Participant with respect to any assets of the Company.

P.AMENDMENT OR TERMINATION.

The Board of Directors may terminate or suspend the Plan at any time. The Committee may amend the Plan at any time; provided that no amendment shall retroactively and adversely affect the payment of any award previously made. Notwithstanding the foregoing, no amendment adopted following the occurrence of a Change in Control shall be effective if it (1) would reduce a Participant’s Individual Target Award for the Performance Period in which the Change in Control occurs, (2) would reduce an award payable to a Participant based on the achievement of Performance Goals in the Performance Period before the Performance Period in which the Change in Control occurs, or (3) modify the provisions of this Article P.

Q.SUCCESSORS AND ASSIGNS.

This Plan shall be binding on the Company and its successors or assigns.

R.GOVERNING LAW.

The law of the State of Delaware shall govern all question concerning the construction, validity and interpretation of the Plan, without regard to the state’s conflict of laws rules.

S.INTERPRETATION AND SEVERABILITY.

In case any one or more of the provisions contained in the Plan shall for any reason be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision of the Plan, but the Plan shall be construed as if such invalid, illegal or unenforceable provisions had never been contained herein.
