Vancouver, British Columbia--(Newsfile Corp. - May 8, 2026) - HIVE Digital Technologies Ltd. (TSXV: HIVE) (NASDAQ: HIVE) (FSE: YO0) (BVC: HIVECO) ("HIVE"), through its wholly owned subsidiary BUZZ High Performance Computing ("BUZZ"), today announced it has contracted a new fibre optic network overbuild and upgrade of the carrier transport network at its Grand Falls Data Centre in New Brunswick. This is a critical infrastructure step to advance the HIVE New Brunswick campus to a Tier III HPC enabled data center. The estimated capital commitment from HIVE will be approximately $3.1 million over 5 years (all amounts in US dollars, unless otherwise indicated).

Proceeds from HIVE's recent $115 million 0% exchangeable note issuance are being deployed towards reaching the Company's growth targets in GPU AI and Tier III HPC data center growth. The conversion of the New Brunswick is amongst the Company's targets this year, and this new fiber optic network marks an advancement in this goal.

Grand Falls is already energized at 70 MW gross load, with buildings and core electrical infrastructure in place. BUZZ is converting the site into a 50 MW Tier III+ AI factory designed for enterprise, government, and sovereign AI workloads.

To move intelligence at scale, Canada needs specialized optical fibre, and HIVE's BUZZ is partnered with Canada's largest carrier¹ to build this in New Brunswick.

In partnership with a Canadian carrier, BUZZ is upgrading Grand Falls with dedicated high-capacity optical wavelength services, including multiple 100 Gbps and 400 Gbps connections. Delivery is expected to begin in Q3 2026. The Canadian carrier will have substantial capital expenditures beyond HIVE's capital commitment, to complete the installation of these high-speed fiber connections.

"AI is the new industrial race," said Frank Holmes, Executive Chairman of HIVE and BUZZ. "Countries that build sovereign AI factories will raise their productivity and security through data sovereignty, ensuring data doesn't leave the countries borders, providing those nations greater data IQ. Countries that do not have their own sovereign AI infrastructure will depend on foreign infrastructure and thus rent intelligence from others."

Mr. Holmes added: "The fibre overbuild is the superhighway that moves that intelligence to customers. Power plus fibre plus GPUs equals an AI factory. New Brunswick has the chance to become one of Canada's most important AI infrastructure hubs. We are flourishing in the AI token economy, and our vision is to consume electrons and export tokens. The vision is to turn Canadian power into Canadian AI tokens of intelligence."

Aydin Kilic, President and CEO of HIVE, said: "Connectivity is a prerequisite of AI factory development. Power alone does not make a sovereign AI facility; the network that carries compute to customers is equally critical. By securing exclusive dedicated network capacity at Grand Falls, we are creating the infrastructure to service enterprise and sovereign AI customers with the redundancy and throughput the AI market demands. As our GPU AI cloud offering doubles in size this year from 5,500 GPUs to 11,000 GPUs, we are excited to expand our HPC colocation business as well by bringing 50 MW of Tier III HPC data center capacity online, to accelerate the growth of BUZZ."²

Craig Tavares, President and COO of BUZZ, said: "Grand Falls is being built for the sovereign AI strategy that Canada needs: Canadian-owned, Canadian-operated, secure, scalable, and designed for sensitive workloads on Canadian soil. With 70 MW of powered infrastructure, a 32-acre expansion path, Tier III design underway, and dedicated optical fibre capacity, BUZZ is preparing to bring one of Canada's largest sovereign AI campuses to market."
