Context

These transactions reflect award vesting and settlement (awards convertible to ordinary shares) and share withholding to cover taxes — a routine corporate compensation event, not an open-market sale or purchase.
For clarity: code M entries represent conversion/exercise of awards into shares; code F entries represent shares withheld to satisfy tax withholding. This is effectively a cashless settlement for the tax amount.
