Tomlinson Patrick 4

What Happened

• Patrick Tomlinson, President and CEO of Mercer (a business of Marsh & McLennan Companies), had 1,228 restricted stock units (RSUs) vest and convert into common stock on 2026-03-15 (1-for-1 conversion). Of those 1,228 shares, 627 were withheld by the company to cover taxes (disposed) at $172.15 per share for a withholding value of $107,938. Tomlinson received the remaining 601 shares (approx. $103,516 at $172.15/share).
• This was a vesting/distribution of previously granted RSUs (granted March 1, 2023), not an open-market purchase or sale; withholding to cover tax liability is routine.

Context

• This is a routine RSU vesting and share-withholding for taxes (a non-market sale to satisfy tax obligations), which does not by itself indicate a change in the insider’s market view. The exercise price reported as $0.00 reflects RSU conversion rather than option exercise requiring cash payment.
