Context

This was a routine RSU vesting event with a sell-to-cover (surrender) for taxes, not an open-market sale or a discretionary purchase—common for compensation vesting. Code M indicates conversion/exercise of derivative RSU awards; code F indicates shares used to satisfy tax obligations. Such transactions usually reflect compensation mechanics rather than a directional insider investment decision.
