Vitalone Britt J. 4

What Happened

• Britt J. Vitalone, Executive Vice President & CFO of McKesson (MCK), had 1,207 restricted stock units (RSUs convert/vest) on 2026-05-21. Of those, 447 shares were withheld to cover taxes at $766.50 per share, totaling $342,626. The vest/conversion is reported as a derivative exercise/conversion (code M) and the withholding is reported as a tax withholding disposition (code F).
• Net shares retained from this vesting: 1,207 - 447 = 760 shares. This was a routine vesting/tax-withholding event rather than an open-market purchase or a voluntary sale.

Key Details

• Transaction date: 2026-05-21; Form 4 filed: 2026-05-26 (reporting period 2026-05-21).
• Reported entries: 1,207 shares acquired via exercise/conversion (price $0.00); 447 shares disposed/withheld at $766.50/share for taxes (total ~$342,626).
• Shares owned after transaction: not specified in the provided filing excerpt; net retained from this vesting = 760 shares.
• Footnotes: F1 = withholding of shares to cover taxes related to the vesting; F2 = these RSUs vest 1/3 on 5/21/2025, 1/3 on 5/21/2026, and 1/3 on 5/21/2027.
• Transaction codes: M = exercise/conversion of derivative (RSU vesting), F = tax withholding.

Context

• This was a standard RSU vesting event with a cashless-like settlement (shares withheld to satisfy tax obligations). Such withholding-driven dispositions are routine and do not necessarily signal an intentional sale of stock by the insider.
• Code M here represents the conversion/exercise of a derivative award (RSUs) into common shares. The meaningful cash flow reported is the tax withholding amount (~$342.6K); no open-market sale or purchase was reported.
