The stock-based award information presented below reflects the Reverse Stock Split effected on July 2, 2026. In connection with the Reverse Stock Split, proportionate adjustments were made to the number of shares of common stock available for issuance and the number of shares of common stock issuable upon the vesting and settlement of existing equity grants under the Company’s equity compensation plan. See Note 2. Significant accounting policies and recent accounting pronouncements for further information on the Reverse Stock Split.

In connection with the closing of the Mergers on September 3, 2025, the Company adopted the Amended and Restated American Bitcoin Corp. 2025 Omnibus Incentive Plan (the "ABTC 2025 Plan"), which amended and restated the predecessor Gryphon Digital Mining, Inc. 2024 Omnibus Incentive Plan. The ABTC 2025 Plan provides for the grant of stock options, stock appreciation rights, restricted stock, restricted stock units, performance grants, and other stock-based awards to employees, consultants, and directors of the Company and its affiliates. As of the ABTC 2025 Plan’s effective date, 12,130,948 shares of the Company's common stock were reserved for

issuance under the ABTC 2025 Plan, subject to an annual automatic increase on each January 1 from 2026 through 2035, equal to the lesser of (a) the excess of 20% of the Company's fully diluted shares outstanding as of the preceding December 31 over the shares then reserved under the ABTC 2025 Plan, and (b) such number as determined by the Company's board of directors. Shares subject to awards that are cancelled and forfeited, and shares returned through certain other mechanisms, are returned to the share reserve and become available for future grants.

In the six months ended June 30, 2026, the Company granted 181,493 RSUs with service-based vest conditions to certain employees and non-employee directors of the Company and its affiliates.
