Pay vs Performance Disclosure [Table]

Pay Versus Performance

This disclosure has been prepared in accordance with regulations promulgated under Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and is not necessarily representative of the value actually realized by our NEOs during any fiscal year or how the Compensation and Talent Committee uses Company or individual performance to determine payouts or awards. For information concerning the Company’s

pay-for-performance

philosophy and how the Company aligns NEO compensation with the Company’s performance, see the Compensation Discussion and Analysis beginning on page

of this proxy statement.

The following tables and narratives set forth information regarding: (i) the total compensation of our Principal Executive Officer (PEO), Mr. Brian S. Tyler, and our

non-PEO

Named Executive Officers (collectively, the

Non-PEO

NEOs) as presented in the Summary Compensation Table (SCT) for each of the past three fiscal years; (ii) “compensation actually paid” (CAP) to our PEO and our

Non-PEO

NEOs, as calculated pursuant to Item 402(v) of Regulation

S-K

(Item 402(v)); (iii) certain financial performance measures, including Total Shareholder Return (TSR),

after-tax

net income (loss) attributable to McKesson Corporation, prepared in accordance with GAAP (Net Income), and our Company-Selected Measure, Adjusted EPS for incentive

programs;

and (iv) the relationship of CAP to those certain financial performance measures.

Compensation Actually Paid vs. Total Shareholder Return [Text Block]

Compensation Actually Paid (CAP) versus TSR:

As shown in the first table of this Pay versus Performance section, the PEO’s and

Non-PEO

NEOs’ CAP values are higher than the corresponding grant date fair values in the SCT, which is consistent with the Company’s positive TSR each year, as shown in the graphs immediately above and below. This is due primarily to the Company’s use of equity incentives, the value of which is tied directly to stock price in addition to the Company’s financial performance. Our executive compensation program emphasizes equity-based pay, with 77% of our PEO’s target direct compensation, and 63% of our

Non-PEO

NEOs’ target direct compensation (on average) delivered via equity-based awards.

Compensation Actually Paid vs. Net Income [Text Block]

CAP versus Net Income:

The Compensation and Talent Committee does not use Net Income to determine compensation opportunity or outcomes.

The Committee believes that Adjusted EPS is a superior indicator of core operating performance and profitability. In addition, it is common for our investors to use Adjusted EPS and other metrics to inform their views of historical and future expectations for underlying operational performance. Net Income, on the other hand, can show variability year over year due to timing of sp

ific events or because of unusual or

non-recurring

events. For example, in the table above, there is a large net loss in FY 2021 Net Income, which was primarily attributable to the opioid litigation settlement charge included in our FY 2021 GAAP results of operations. The actual cash impact of that settlement will take place over multiple years, and the FY 2021 Net Income loss figure does not reflect the actual underlying performance of the business, which is better reflected by the other metrics included in our incentive programs, as well as the Company’s 46% TSR for that fiscal year.

Therefore, we would not necessarily expect to see alignment between Net Income (loss) and CAP. The Compensation and Talent Committee is focused on alignment of our compensation programs to metrics that most appropriately measure our profitability and sustainable long-term growth.

Compensation Actually Paid vs. Company Selected Measure [Text Block]

CAP versus Adjusted EPS:

The chart below compares the PEO’s and

Non-PEO

NEOs’ CAP values to our Company-Selected Measure (CSM), Adjusted EPS. As noted above, for each fiscal year presented, CAP values are higher than the c

orr

esponding grant date fair value of stock awards shown in the SCT, which is consistent with our growing Adjusted EPS.

The Company focuses on Adjusted EPS in our incentive plans because earnings per share is one of the principal measures used by investors to assess financial performance results and establish a price for the Company’s

uity, and it is a central component of our guidance to investors. The use of Adjusted EPS in our incentive plans aligns our executives’ interests with the broader set of strategic objectives they are tasked to manage, keeping enterprise value and shareholder interests at the forefront of management decisions on both a short- and long-term basis. Accordingly, Adjusted EPS is included as a key metric in both our annual and long-term incentives.

Given this emphasis on Adjusted EPS, its impact on the value of the Company’s shares and therefore CAP values — both positive and negative — is significant. Adjusted EPS drives a significant portion of the Company’s annual cash incentive and determines a significant portion of PSU award payouts to be earned during any three-year PSU performance period.

Total Shareholder Return Vs Peer Group [Text Block]

Total Shareholder Return (TSR): Company versus Peer Group:

The Company’s three-year cumulative T

has significantly exceeded that of the S&P 500 Health Care Index. We selected the S&P 500 Health Care Index as the comparator because it is generally available to investors and broadly used by other companies in the same industry.
