Lau Michele 4

What Happened

• Michele Lau, EVP and Chief Legal Officer of McKesson (MCK), had 724 restricted stock units (RSUs convert/vest into shares) on 2026-05-21. Of those, 285 shares were withheld to satisfy tax withholding at a per-share value of $766.50, totaling $218,453. The net increase in Lau’s holdings from this vesting was 439 shares (724 vested − 285 withheld).
• This was not an open-market sale or purchase by the insider; the 285-share disposition reflects tax withholding (company withholding/cashless tax payment), a routine administrative step when RSUs vest.

Context

• This is a routine RSU vesting event with company withholding of shares for taxes (commonly called a cashless tax withholding), not a market sale or insider purchase signaling a view on the stock.
• For investors, purchases by insiders can be more informative than routine vesting/withholding events; this filing documents compensation-related vesting rather than a discretionary trade.
