Vancouver, British Columbia--(Newsfile Corp. - September 18, 2025) - BUZZ High Performance Computing ("BUZZ HPC"), a wholly owned subsidiary of HIVE Digital Technologies Ltd. (TSXV: HIVE) (NASDAQ: HIVE) (FSE: YO0) (the "Company" or "HIVE"), a Canadian AI cloud provider and NVIDIA Cloud Partner, today announced the acquisition of a 7.2-megawatt (MW) data centre site in the Greater Toronto Area (GTA).

The site will form the foundation of a new Tier III+ data centre built specifically for AI workloads. The facility will serve dual purposes: offering colocation services to enterprises, institutions, and governments seeking sovereign data infrastructure, and deploying BUZZ HPC's own accelerated compute clusters to support high-performance AI development and deployment.

This site will also support BUZZ HPC's recently announced partnership with Bell Canada and its Bell AI Fabric ecosystem, expanding access to sovereign accelerated compute infrastructure nationwide.

Engineered for sustainability and performance, the facility will leverage Ontario's clean electricity grid and deploy liquid-cooling systems capable of supporting GPU racks of 150 kW and higher. This design enables hosting of the most advanced GPU clusters, optimized for high-density AI training, fine-tuning, and inference.

Craig Tavares, President and COO of BUZZ HPC, stated: "This acquisition represents an important step forward for BUZZ HPC and for Toronto's role in the growing AI sector. Together with the Bell AI Fabric partnership, the new data center will provide the power and infrastructure needed to support Canadian research, business innovation, and secure, high-performance deployments. Whether through colocation services or direct access to our accelerated compute clusters, our customers and partners will benefit from infrastructure designed for scalability, reliability, and data sovereignty."

Why Sovereign AI Infrastructure Matters

Sovereign AI infrastructure ensures sensitive data stays in Canada under Canadian law, protecting it from foreign regulations. By keeping facilities Canadian-owned and operated, BUZZ HPC helps secure the country's digital independence, safeguard critical data from geopolitical risks, and provide universities, researchers, and startups with local access to GPU power. By investing in this sector, we aim to drive economic growth, generate high-value employment, and reinforce Canada's leadership in AI.

Toronto's Role in Canada's AI Future

Toronto is home to a globally recognized AI ecosystem, anchored by the Vector Institute, the University of Toronto, other leading institutions, and hundreds of startups. The GTA has attracted billions in AI investment and built one of North America's fastest-growing AI workforces. By adding sovereign, sustainable compute capacity in the heart of this ecosystem, BUZZ HPC strengthens Canada's ability to innovate securely and compete globally.
