BlackRock (BLK) Marc Comerchero Receives RSUs; Shares Withheld for Taxes
What Happened
Marc D. Comerchero, BlackRock’s Principal Accounting Officer, had 549 restricted stock units (RSUs) vest on Jan 31, 2026 (granted/received at $0). To satisfy tax withholding on vested awards, BlackRock withheld and disposed of 558 shares on Jan 30, 2026 at $1,118.94 per share, generating $624,369. The transactions result in a net change of nine fewer shares (558 disposed vs. 549 acquired). These withholding sales are a routine method to cover tax obligations and do not necessarily signal a voluntary market sale.
Key Details

- The reported award includes common stock and RSUs that vest over 1–4 years; each RSU is payable in one share of common stock (F2).
- The 549 RSUs reflect a 2022 Performance Incentive award: $350,240 converted to 471 RSUs (using a $743.61 price) and then adjusted to 116.6% based on performance, resulting in 549 RSUs (F3).

Context
- This filing shows a standard tax-withholding disposition tied to RSU vesting rather than an open-market sale initiated by the insider. Such dispositions commonly occur when a company withholds shares to cover tax withholding obligations.
- The award conversion and performance adjustment explain why 549 RSUs were delivered; the withholding quantity can differ from the vested amount based on tax calculations.
