A copy of the Press Release is furnished herewith as Exhibit 99.1 and is incorporated herein by reference.

Item 8.01. Other Events.

On March 31, 2025, American Data Centers Inc., a Delaware corporation and former wholly owned subsidiary of the Company (“ADC”), completed a series of transactions providing for the launch of American Bitcoin Corp., a strategic initiative focused on industrial-scale Bitcoin mining and strategic Bitcoin reserve development and monetization (the “Transactions”).

To effectuate the Transactions, ADC, Hut 8 Corp., a Delaware corporation, and certain of its subsidiaries (“Hut 8”), and the stockholders of ADC entered into a Contribution and Stock Purchase Agreement, pursuant to which Hut 8 contributed to ADC substantially all of Hut 8’s wholly owned ASIC bitcoin miners in exchange for newly issued stock representing 80% of the issued and outstanding equity interests of ADC after giving effect to the issuance. At the closing of the Transactions, ADC changed its name to American Bitcoin Corp. (“American Bitcoin”).

In connection with the Transactions, American Bitcoin and Hut 8 also entered into definitive agreements providing for Hut 8 and its personnel to provide day-to-day commercial and operational management services and ASIC colocation services to American Bitcoin, in each case on an exclusive basis for so long as such agreements remain in effect. Hut 8 and its personnel will also provide back-office support services to American Bitcoin pursuant to a shared services agreement with American Bitcoin.

As a result of the Transactions, American Bitcoin has become a subsidiary of Hut 8 in which the Company holds a minority interest.
