Prusak Matthew 4

What Happened
Matthew Prusak, President and Interim CFO of American Bitcoin Corp. (ABTC), was granted 477,708 restricted stock units (RSUs) on February 24, 2026. The grant is reported as a derivative award (transaction code A) with an acquisition price shown as $0.00 — typical for compensation grants rather than cash purchases or sales. Each RSU is a contingent right to one share of the company's Class C common stock.

• Shares owned after transaction: not specified in the provided filing.
• Footnotes: F1 — each RSU converts to one share of Class C common stock; F2 — RSUs vest ratably in three equal annual installments on each of the first, second and third anniversaries of the grant date.

Context
RSU grants are a form of executive compensation and do not represent immediate purchases or sales — the units convert to actual shares only as they vest. Because these RSUs vest over three years, any eventual increase in Prusak’s share ownership and potential dilution will occur over that vesting schedule rather than immediately. This filing is informational about compensation rather than a direct market signal like an open-market buy or sell.
