Context

RSU grants are compensation awards and not an outright cash purchase; vesting schedules mean future share delivery is contingent.
The disposals here are tax-withholding actions, a common administrative step when restricted awards vest and do not necessarily indicate a voluntary sell decision or a change in insider sentiment.
