Context
This was a routine vesting/conversion of previously granted RSUs, not an open-market purchase or sale. The derivative code "M" denotes exercise or conversion; here it reflects RSUs settling into common shares. Such vesting events are standard compensation mechanics and do not necessarily signal insider buying or selling intent.
