• Net shares received: 5,482 − 2,257 = 3,225 shares retained by insider.
• Footnotes: F1–F3 confirm RSUs convert 1:1 into common stock and that the Feb 9, 2026 closing price was used to calculate shares withheld; the award vests per a 3‑year schedule (vesting commencement Feb 10, 2025).
• Shares owned after the transaction: not specified in the provided filing excerpt.
• Nature: This is an RSU vesting event with routine tax withholding (not an open‑market purchase or discretionary sale).

Context
RSU vesting is a common form of compensation conversion into stock; withholding/sale of shares to cover taxes is routine and does not necessarily signal a change in the insider’s view of the company. The filing shows conversion of the derivative award and the associated tax withholding rather than a voluntary market sale or new purchase.
