Context
The "M" transactions reflect conversion/settlement of restricted stock units (RSUs) into shares; zero-dollar disposals reported on the settlement date commonly indicate net share settlement or withholding (e.g., to satisfy taxes) rather than a cash sale. The 09/08 transaction was an open-market sale generating ~$41k. These entries show routine executive compensation vesting plus a modest sale, not an outright cash purchase signal.
