General

American Bitcoin is a purpose-built
Bitcoin accumulation vehicle and aims to pursue that goal through a levered strategy that combines efficient Bitcoin mining, disciplined
Bitcoin reserve expansion and focused ecosystem engagement.

Prior to September 3, 2025,
we were a digital-asset mining company known as Gryphon Digital Mining, Inc. On September 3, 2025, we completed our stock-for-stock merger
transactions (the “Mergers”) pursuant to the Agreement and Plan of Merger, dated as of May 9, 2025 (the “Merger Agreement”),
by and among us, GDM Merger Sub I Inc., GDM Merger Sub II LLC and pre-merger American Bitcoin Corp. (“Historical ABTC”), pursuant
to which we acquired Historical ABTC and we changed our name from Gryphon Digital Mining, Inc. to American Bitcoin Corp. Shortly before
the closing of the Mergers, we effected a 5-for-1 reverse stock split of our common stock (the “Reverse Stock Split”) and
our common stock was reclassified as Class A common stock. At the closing of the Mergers, we issued shares of Class A common stock and
Class B common stock to ABTC stockholders based upon an agreed exchange ratio specified in the Merger Agreement. In connection with the
closing of the Mergers, our Class A common stock began trading on the Nasdaq under the symbol “ABTC” on September 3, 2025.
