Context

• These entries reflect an RSU award (future-delivery equity) and routine tax-withholding (cashless share withholding), not an open-market sale or purchase. RSU grants indicate potential future ownership if vesting conditions are met; withheld shares to cover taxes are common and do not necessarily signal a view on the company’s stock.
