Context
This was a vesting/settlement of RSUs (derivative conversions), not a purchase or open-market sale. Withholding shares to cover taxes is standard practice for RSU vesting and does not necessarily signal buying or selling intent. The filing reports the mechanics and tax withholding; it does not state Berg’s total ownership after the event.
