Context This was primarily an RSU vesting and settlement event, not an open-market investment decision. Shares withheld to cover taxes are a routine administrative disposition and do not necessarily indicate a change in the insider’s view of the company. The M code reflects conversion/settlement of RSUs into common stock; the F code reflects shares withheld to meet tax obligations.
