Context

• This filing reflects an award/vesting event and routine tax-withholding (not an open‑market sale or purchase). Withholding of shares to cover taxes is common and does not necessarily indicate a change in insider sentiment. The transaction involves vested restricted/performance stock units (PSUs) rather than a cash purchase or open-market sale.
