Context

This was a routine RSU vesting and tax-withholding settlement (a cashless/net settlement), not an open-market sale or purchase. Tax-withholding disposals on vesting are common and do not necessarily signal a change in insider sentiment. The filing documents conversion of RSU derivatives into shares and the automatic withholding to cover taxes.
