Context
- The March 6 sale was a tax-withholding sale tied to RSU vesting (routine, automatic), which is different from a discretionary open-market sale and typically does not by itself indicate insider sentiment.
- The RSU and derivative awards are grants, not purchases; vesting schedules mean any future economic benefit depends on continued service and vesting dates.
