Context
This was a routine vesting/conversion of RSUs rather than an open-market buy or discretionary sale. The withholding of shares to cover taxes is a common, administrative step and does not necessarily signal a judgment about the company’s prospects. Transaction codes: M = exercise/conversion of derivative (here, RSUs converting to shares); F = shares withheld to pay taxes.
