Context

• These were restricted stock unit awards (not open-market purchases). The disposal was a company/plan tax-withholding action (common when RSUs vest), not an open-market sale that signals sentiment. RSU grants reflect compensation and vesting schedules; withheld shares to cover taxes are routine and do not necessarily indicate buying or selling intent.
