Witherspoon Charles 4

What Happened

• Charles Witherspoon, Vice President & Treasurer of West Pharmaceutical Services (WST), had restricted stock units convert into 60.22 shares of common stock on February 20, 2026. To satisfy tax withholding, 22.069 of those shares were withheld/disposed at $241.12 per share for a total withholding value of $5,321.
• The filing shows the RSU derivative was converted (reported as "M" — exercise/conversion of derivative) and a separate "F" transaction for shares withheld to pay taxes. Net shares delivered to Witherspoon after withholding were approximately 38.151 shares (60.22 − 22.069).

Key Details

• Transaction date: February 20, 2026; Form 4 filed Feb 23, 2026 (timely).
• Conversion: 60.22 shares reported as acquired via derivative conversion (code M).
• Tax withholding: 22.069 shares disposed at $241.12 each, totaling $5,321 (code F).
• Footnotes: RSUs convert one-for-one into common stock. The RSUs came from a grant of 237 RSUs on Feb 18, 2025 that vest in four equal annual installments (plus dividend equivalents) each Feb 20.
• Shares owned after the transaction are not specified in this report.

Context

• This appears to be a routine RSU vesting event with shares withheld to cover taxes (a common, non-speculative transaction). The derivative entry reflects conversion/cancellation of RSUs into common shares; the withholding is effectively a cashless tax payment rather than an open-market sale for investment purposes.
