Cathedra Bitcoin Announces Business Updates

Toronto, Ontario--(Newsfile Corp. - April 8, 2026) - Cathedra Bitcoin Inc. (TSXV: CBIT) (OTCQB: CBTTF) (the "Company" or "Cathedra"), a developer and operator of power and digital infrastructure assets across North America, is pleased to announce the following corporate and operational updates.

New Hosting Partnership

The Company has entered into a new hosting agreement which is expected to establish a stable, long-term revenue stream, made possible by its strategy of building off-peak infrastructure to access some of the lowest energy prices in the industry. This agreement will utilize 80% of the 15 megawatt ("MW") capacity at the Shire site in Kentucky and is expected to represent roughly 25% of the Company's total hosting capacity. The agreement reflects Cathedra's off-peak energy strategy, which allows the Company to offer hosting services at competitive rates by optimizing power consumption around utility pricing schedules. The ability to deliver cost-effective hosting, even in periods of difficult mining economics that have pressured less disciplined operators, is what continues to attract quality hosting customers and support demand across Cathedra's sites.

This agreement further diversifies Cathedra's hosting customer base and is expected to strengthen the recurring revenue profile that the Company has been building across its portfolio of sites. The addition of a new hosting relationship at the Shire site reflects continued demand for Cathedra's infrastructure and reinforces the Company's position as a premier hosting provider in the bitcoin mining industry.

The timing of this agreement is particularly meaningful as the Company advances toward the closing of its previously announced business combination with Sphere 3D Corp. (NASDAQ: ANY). If completed, the combination is expected to create a next-generation high density computing power infrastructure company, bringing together Sphere's established capital markets access, including its Nasdaq listing, and efficient fleet of miners with Cathedra's robust energy portfolio and proven infrastructure development expertise. Entering the combination with a diversified hosting portfolio and a mix of steady third-party cash flows is expected to support the Combined Company's efforts to pursue scalable, high-efficiency operations across North America. For further information concerning proposed business combination with Sphere, please see the Company's filings under the Company's SEDAR+ profile on www.sedarplus.ca.
