Context

• This was an award vesting and settlement, not an open-market purchase or sale of previously held shares. The withholding of shares to cover taxes is a routine cashless settlement method and does not by itself signal a buy/sell decision by the insider.
• Transaction codes: M = exercise/conversion of a derivative (here, RSU settlement); F = shares withheld to satisfy tax liabilities.
