Context
This was routine RSU vesting and a net-share settlement to cover tax withholding — not an open-market sale or a directional buy/sell signal. Transaction code M denotes conversion/exercise of a derivative (the RSU), and F denotes shares withheld to pay taxes. Routine vesting and withholding are common for equity-compensated executives and do not by themselves imply a change in the insider’s view of the company.
