Disposition of Hosting Facility – ASC 205-20 Classification Assessment

As of March 31, 2025, management was evaluating strategic alternatives for the Company’s mining and hosting facility in LaFayette, Georgia following the expiration of the Company’s primary hosting agreement earlier in the month. While the Company engaged in preliminary discussions with potential counterparties, no approved plan of sale existed at March 31, 2025, multiple alternatives were still being evaluated, and the Board of Directors did not approve a plan to sell the facility until April 1, 2025.
