MACDONALD LAURA ANN 4

What Happened Laura Ann MacDonald, Vice President and PAO of Cognex Corporation (CGNX), had 368 restricted stock units (RSUs) convert to common shares on March 15, 2026 (exercise/conversion of derivative, code M). Of those, 109 shares were withheld to satisfy tax withholding obligations (disposition, code F) for a reported withholding value of $5,230. The RSUs had no exercise price (reported at $0.00), so the transaction represents vested awards rather than a market purchase.

Context This was an RSU vesting event (award vesting) with a routine tax-withholding disposition, not an open-market sale or purchase. When RSUs vest, companies commonly withhold shares to cover taxes — that withholding looks like a disposition on the Form 4 but does not necessarily indicate a decision to sell for investment reasons. The vesting follows the grant schedule (20%/30%/50% over three anniversaries) from the March 15, 2024 grant.
