Share-Based Compensation
The Company provides share-based compensation to its employees, officers, and non-employee directors, including restricted stock units (“RSUs”), performance-based stock units (“PSUs”), and an employee stock purchase plan (“ESPP”) (collectively, “share-based awards”). Most of the share-based awards are granted in the first quarter of each fiscal year.
Share-based compensation expense for the share-based awards is recognized for the portion of awards ultimately expected to vest. The Company estimates the number of share-based awards that will ultimately vest primarily based on historical experience. The estimated forfeiture rate established upon grant is re-assessed throughout the requisite service period and is adjusted when actual forfeitures occur. The actual forfeitures in future reporting periods could be higher or lower than current estimates.
Share-based compensation expense is classified in the Consolidated Statements of Operations in the same manner as cash compensation paid to the Company’s employees and included in “Selling, distribution, general, and administrative expenses.”

Stock Plans
In April 2022, the Company’s stockholders approved the McKesson Corporation 2022 Stock Plan (the “2022 Stock Plan”), which permits the grant of awards in the form of restricted stock, RSUs, PSUs, stock options, and other share-based awards to selected employees, officers, and non-employee directors. As of March 31, 2026, 4.0 million shares remain available for future grant under the 2022 Stock Plan.
Restricted Stock Unit Awards
RSUs entitle the holder to receive a specified number of shares of the Company’s common stock, which vest over a period of generally three to four years as determined by the Compensation Committee at the time of grant. The fair value of the award is determined based on the price of the Company’s common stock on the grant date and the related share-based compensation expense is recognized over the vesting period on a straight-line basis.
Non-employee directors receive an annual grant of RSUs, which vest immediately and are expensed upon grant. The director may elect to receive the underlying shares immediately or defer receipt of the shares if they meet director stock ownership guidelines. The shares will be automatically deferred for those directors who do not meet the director stock ownership guidelines. At March 31, 2026, approximately 33,000 RSUs for the Company’s directors were vested.
Performance Stock Unit Awards
PSUs are conditional upon the attainment of market and performance objectives over a specified period. The number of vested PSUs is assessed at the end of a three-year performance period upon attainment of meeting certain earnings per share targets, average return on invested capital, and for certain participants, total shareholder return (“TSR”) relative to a peer group of companies. The Company uses the Monte Carlo simulation model to measure the fair value of the total shareholder return portion of the PSUs. Starting in fiscal 2026, PSU awards are based on cumulative three‑year earnings per share and average return on invested capital targets and, for certain participants, include a TSR modifier. For awards with a TSR modifier, the Company uses a Monte Carlo simulation model to measure grant‑date fair value. For awards without a TSR modifier, the PSUs are measured at the grant-date market price. PSUs have a requisite service period of generally three years. Expense is attributed to the requisite service period on a straight-line basis based on the fair value of the PSUs, adjusted for the performance modifier at the end of each reporting period.
The weighted-average assumptions used in the Monte Carlo valuations were as follows:

Employee Stock Purchase Plan
The Company has an ESPP under which 23.1 million shares have been authorized for issuance. The ESPP allows eligible employees to purchase shares of the Company’s common stock through payroll deductions. The deductions occur over three-month purchase periods and the shares are then purchased at 85% of the market price at the end of each purchase period. Employees are allowed to terminate their participation in the ESPP at any time during the purchase period prior to the purchase of the shares, subject to the Company’s insider trading policies and procedures. The 15% discount provided to employees on these shares is included in share-based compensation expense. The shares related to funds outstanding at the end of a quarter are included in the calculation of diluted weighted-average shares outstanding. These amounts have not been significant for all years presented. The Company recognizes costs for employer matching contributions as ESPP expense over the relevant purchase period. Shares issued under the ESPP were not material in fiscal 2026, fiscal 2025, and fiscal 2024. At March 31, 2026, 3.1 million shares remain available for issuance.

About Stock Compensation Disclosures

Stock-based compensation disclosures detail the equity awards granted to employees and executives — including stock options, restricted stock units (RSUs), and performance shares — along with the valuation methods and assumptions used to expense them. This section reveals the true cost of talent retention and the alignment between management incentives and shareholder interests.

Key signals: total unrecognized compensation expense and its expected recognition period signal future earnings headwinds from already-granted awards. For stock options, examine Black-Scholes assumptions — expected volatility, risk-free rate, and expected term — as understating any of these reduces reported compensation expense. Compare stock compensation expense as a percentage of revenue against peers to assess dilution cost. Watch vesting schedules for acceleration clauses tied to change-of-control events. Performance-based awards with undemanding targets may indicate weak governance. Add back stock compensation to operating cash flow to calculate a more conservative free cash flow figure.
