Context
This was a standard vesting/conversion and net settlement (cashless) tax-withholding event—not an open-market sale. Transaction codes: M = exercise/conversion of derivative (here, RSU/PRSU conversions); F = shares withheld for tax obligations. Such withholding transactions are routine for executives receiving equity awards and do not on their own indicate a buy/sell signal.
