On August 11, 2026, Robert W. McMahon, SVP & Chief Financial Officer of West Pharmaceutical Services Inc., had previously granted restricted stock units (RSUs) vest into common stock and simultaneously satisfied associated tax obligations via same‑day sales. Two RSU tranches vested: 794.469 shares and 6,354.736 shares of RSUs were converted into an equal number of common shares (coded as transaction type M), increasing his direct common stock holdings before tax dispositions. To cover withholding taxes, he disposed of 345.515 shares and 2,763.675 shares of common stock, respectively, at approximately $351.37 per share (coded as F), resulting in routine, non‑discretionary sales tied to the vesting events. After these transactions, McMahon directly owned 7,020.506 shares following the larger vest, and 3,429.445 shares following the smaller vest, with the stock valued around $351.77 per share based on recent market data. These activities represent standard equity compensation vesting and related tax withholding for an executive officer, rather than open‑market purchases or discretionary selling.
