Context

• Code M indicates conversion/exercise of a derivative (here, RSUs/options) into underlying common shares; code F denotes shares withheld to satisfy tax withholding. No open‑market sale was reported — this looks like a routine RSU vesting/conversion with a small number of shares withheld for taxes. As a 10% owner, this is insider activity but not the same signal as an open-market purchase or sale by an executive.
