Vitalone Britt J. 4

What Happened

• Britt J. Vitalone, Executive Vice President & Chief Financial Officer of McKesson (MCK), had 1,038 restricted stock units (RSUs) vest on 2026-05-20. The RSUs converted to 1,038 common shares (derivative exercise/conversion, code M).
• To satisfy tax withholding (code F), 409 of those shares were surrendered at a reported per-share value of $754.68, totaling $308,664. That leaves roughly 629 shares delivered to Vitalone net of withholding.
• This was a vesting/compensation event, not an open-market purchase or sale.
