Hyperscale Data Upgrading 1,000 New Bitmain Antminer S21+Units to Michigan Artificial Intelligence and Bitcoin Campus

Company to Begin Upgrading Bitcoin Mining Fleet and Continues to Hold All Bitcoin in Treasury

LAS VEGAS, Oct. 8, 2025 /PRNewswire/ -- Hyperscale Data, Inc. (NYSE American: GPUS), a diversified holding company ("Hyperscale Data" or the "Company"), today announced that it has completed an order for 1,000 new Bitmain Antminer S21+ miners ("S21+'s") for its Michigan Data Center (the "Michigan Facility"). The Company plans to begin installing the S21+'s as soon as they arrive, which may be as early as Monday, October 13, 2025.

This new deployment marks a key step in Hyperscale Data's optimization program, replacing a portion of older, less-efficient Bitcoin miners with the current generation of high-performance equipment. The installation will occur in approximately 4-megawatt ("MW") phases, enabling the Company to integrate new S21+'s with minimal disruption to existing operations.

"We remain committed to running an artificial intelligence ("AI") data center and Bitcoin mining operation side-by-side at our Michigan Facility," stated Milton "Todd" Ault III, Executive Chairman of Hyperscale Data. "This model enables us to leverage infrastructure and maximize efficiency across two lines of business. By upgrading to the S21+'s, we are increasing productivity while maintaining our long-term focus on Bitcoin accumulation and expanding our AI compute offerings."

S21+'s deliver up to approximately 235 terahashes per second, which represents an approximate 135% increase in processing speed from Hyperscale Data's older S19J Pro Bitcoin miners. Hyperscale Data plans to upgrade approximately 20 MW of Bitcoin miners, which would result in approximately 5,000 total new S21+s's operating at the Company's Michigan Facility. Upon the completion of this planned 20 MW upgrade, the Company expects a significant change in the overall efficiency and output of its Bitcoin mining operations.

Additionally, the Company reminds stockholders that it intends to hold all Bitcoin earned from Bitcoin mining operations on its balance sheet as part of its digital asset treasury strategy while supplementing Bitcoin mining operations with ongoing open market acquisitions of Bitcoin as it moves toward its goal of a $100 million Bitcoin treasury.

About Hyperscale Data, Inc.

Through its wholly owned subsidiary Sentinum, Inc., Hyperscale Data owns and operates a data center at which it mines digital assets and offers colocation and hosting services for the emerging AI ecosystems and other industries. Hyperscale Data's other wholly owned subsidiary, Ault Capital Group, Inc. ("ACG"), is a diversified holding company pursuing growth by acquiring undervalued businesses and disruptive technologies with a global impact.

Hyperscale Data currently expects the divestiture of ACG (the "Divestiture") to occur in the second quarter of 2026. Upon the occurrence of the Divestiture, the Company would be an owner and operator of data centers to support high-performance computing services, as well as a holder of the digital assets. Until the Divestiture occurs, the Company will continue to provide, through ACG and its wholly and majority-owned subsidiaries and strategic investments, mission-critical products that support a diverse range of industries, including an AI software platform, social gaming platform, equipment rental services, defense/aerospace, industrial, automotive, medical/biopharma and hotel operations. In addition, ACG is actively engaged in private credit and structured finance through a licensed lending subsidiary. Hyperscale Data's headquarters are located at 11411 Southern Highlands Parkway, Suite 190, Las Vegas, NV 89141.

On December 23, 2024, the Company issued one million (1,000,000) shares of a newly designated Series F Exchangeable Preferred Stock (the "Series F Preferred Stock") to all common stockholders and holders of the Series C Preferred Stock on an as-converted basis. The Divestiture will occur through the voluntary exchange of the Series F Preferred Stock for shares of Class A Common Stock and Class B Common Stock of ACG (collectively, the "ACG Shares"). The Company reminds its stockholders that only those holders of the Series F Preferred Stock who agree to surrender such shares, and do not properly withdraw such surrender, in the exchange offer through which the Divestiture will occur, will be entitled to receive the ACG Shares and consequently be shareholders of ACG upon the occurrence of the Divestiture.
