Context

• These transactions reflect RSU vesting and routine tax-withholding (a cashless withholding), not an open-market sale or purchase decision. For derivative entries, "M" indicates conversion/exercise of the contingent RSU right into shares; "F" indicates shares withheld to cover taxes. Routine withholding on vesting is common and does not necessarily signal a change in insider sentiment.
