Context
This was a vesting/award event (performance-based RSUs) with a portion of shares withheld to cover taxes — a common, administrative step that does not necessarily reflect a buy/sell decision about the company’s outlook. The filing shows acquisitions (awards) and internal tax-withholding disposals rather than open-market sales or purchases.
