Context
The M-code entries here reflect conversion/settlement of RSUs/PRSU awards (no cash exercise price) and the F-code entries are routine share withholding to cover tax obligations — not open-market sales. Such tax-withhold disposals are common when equity awards vest and do not necessarily indicate a deliberate sell decision by the insider.
