Context

This was a conversion/vesting event, not an open-market purchase or discretionary sale; withholding for taxes is routine and does not indicate a market sale beyond tax obligations.
The M code here represents conversion of RSUs (no cash exercise price); the F code indicates shares withheld to satisfy tax liabilities.
