Context
This was a vesting of performance-based restricted stock units, not an open-market purchase or a voluntary sale. The reported disposition (199,209 shares) reflects company withholding to satisfy taxes upon vesting — a routine administrative action common with RSU/PSU vesting and not necessarily indicative of the insider’s view of the stock.
