Sphere 3D Completes Previously Announced Acquistion Of Cathedra Bitcoin

Sphere 3D Corp. (NASDAQ:ANY) ("Sphere") and Cathedra Bitcoin Inc. (TSXV:CBIT)(OTCQB:CBTTF) ("Cathedra" and together with Sphere, the "Parties") today announced that they have completed the previously announced plan of arrangement (the "Transaction") pursuant to which Sphere acquired all of the issued and outstanding shares of Cathedra under the arrangement agreement entered into on March 5, 2026 (the "Agreement"), and Cathedra is now a wholly-owned subsidiary of Sphere (Sphere, together with Cathedra and their subsidiaries following completion of the Transaction, the "Combined Company"). The Transaction was completed by way of a court-approved plan of arrangement under the Business Corporations Act (British Columbia). The Transaction was approved at a special meeting of the securityholders of Cathedra and at a meeting of the shareholders of Sphere, and by the Supreme Court of British Columbia.

"Closing this combination marks a significant milestone for both companies and our shareholders," said Joel Block, Chief Executive Officer of the Combined Company. "We have integrated Cathedra's energy-centric infrastructure platform with Sphere's public-market presence and robust balance sheet to build a larger, more diversified enterprise with a clear growth trajectory. Together, we offer 53 MW of operational capacity, a pipeline exceeding 100 MW of potential expansion, and a NASDAQ-listed platform designed for scalability. We believe the Combined Company is strategically positioned to generate long-term value by seizing opportunities in high-performance computing and digital asset infrastructure."

Strategic Rationale and Competitive Advantages

The Transaction is expected to deliver greater scale and an expanded US operating footprint, with the Combined Company owning and operating a portfolio of 53 megawatts ("MW") of power capacity across five data centers in Iowa, Kentucky, and Tennessee. This larger platform is also intended to lay a foundation for potential expansion into high-performance compute. With growing demand for compute-intensive workloads, the Combined Company intends to evaluate select opportunities in adjacent high-performance compute and AI infrastructure, leveraging existing power relationships and site capabilities to maximize returns on its power capacity. The expanded operating scale is expected to improve profitability by spreading fixed overhead costs over a larger revenue and asset base.

The combination also diversifies the Combined Company's revenue streams across proprietary mining and hosting services. By integrating Sphere's updated mining machine fleet with Cathedra's data center operations and experience, the Combined Company gains exposure to mining economics while maintaining downside protection through fixed-margin hosting contracts with third parties. These strengths are paired with strong growth prospects supported by a scalable development model and access to capital: Cathedra's low-cost development model and infrastructure-first approach, coupled with Sphere's capital markets expertise, position the Combined Company to capitalize on a robust pipeline of over 100 MW of potential expansion opportunities and to further grow its portfolio of infrastructure assets.

Over time, the Combined Company intends to maximize returns on power capacity by assessing the highest-value applications for its energy resources, including digital asset mining, AI model training, and other compute-intensive workloads that require reliable, cost-effective power at scale.

The Combined Company's bitcoin mining operations and balance sheet include managed power capacity of 53 MW at five data centers across three U.S. states, comprising both data centers owned by the Combined Company and those leased from and/or operated by third parties, as well as 1.2 EH/s of installed proprietary mining hash rate across data centers owned by the Combined Company and third-party hosting providers.
