Context

• The primary event was RSU vesting (an award), not an option exercise purchase. Tax withholding and fractional-share cash settlements are routine following vesting.
• The March 17 sales were executed under a pre-established Rule 10b5-1 plan — a common mechanism for insiders to sell shares on a set schedule.
• These transactions are primarily routine compensation vesting and tax-related withholding plus planned open-market sales; they do not alone indicate the insider’s private view of the company’s prospects.
