This news release constitutes a "designated news release" for the purposes of the Company's amended and restated prospectus supplement dated May 14, 2025 to its short form base shelf prospectus dated September 11, 2024.

Toronto, Ontario--(Newsfile Corp. - June 24, 2025) - BUZZ High Performance Computing ("BUZZ HPC"), a wholly owned subsidiary of HIVE Digital Technologies Ltd. (TSXV: HIVE) (NASDAQ: HIVE) (FSE: YO0) (referred to as the "Company" or "HIVE"), today announced the launch of another NVIDIA Hopper GPU cluster in Quebec - one of three supercomputing clusters it operates across Canada and Sweden. As a NVIDIA Cloud Partner, BUZZ HPC is one of the few Canadian sovereign artificial intelligence ("AI") platforms operating at scale, supporting national innovation through secure, high-performance infrastructure based in Canada. The new cluster featuring NVIDIA Hopper GPUs and scaled with the high-performance NVIDIA Quantum-2 InfiniBand networking platform, is operating near full utilization since launch. BUZZ HPC is rapidly expanding its capacity.

Since 2023, BUZZ HPC has been developing its high-performance computing ("HPC") infrastructure in Canada through the establishment of HPC data centres spanning multiple time zones and languages, through its facilities located in the Provinces of Quebec and New Brunswick. Consequently, management believes that it has positioned itself as a key pillar of Canada's AI ecosystem. BUZZ HPC proudly supports a global community including venture-backed startups, universities, and research teams who are advancing the frontiers of AI and HPC applications. BUZZ HPC's customers rely on BUZZ HPC for flexible and scalable on-demand access to GPU clusters, whether by the hour or through long-term fixed contracts.

Built for Scale. Proven Experience. Canadian Sovereignty.

Our origin as HIVE began with a deployment of approximately 130,000 GPUs in 2018 and has since evolved to operate advanced, large-scale NVIDIA GPU clusters for AI applications, composed of NVIDIA Ampere, NVIDIA Hopper, and very soon, NVIDIA Blackwell GPUs. These GPUs accelerate everything from academic research to enterprise AI applications.

Well before the current wave of AI investment, BUZZ HPC was focused on the inclusion of renewable energy and digital services. Its infrastructure supports both early-stage startups and global enterprises, with the benefit of data residency remaining in Canada.

"Amid what Management believes is growing demand for domestic AI capacity, this latest cluster supports key sectors such as generative AI, autonomous systems, legal tech, genomic medicine, customer service automation, and research institutions focused on machine learning and health sciences," said Frank Holmes, Executive Chairman of HIVE.

Why BUZZ HPC Stands Apart:

• Sovereign AI Cloud: All infrastructure and data remain within jurisdictions of Canada.
• AI-Ready Infrastructure: Cutting-edge accelerated computing infrastructure optimized for large-scale AI workloads.
• Academic & Commercial Focus: Trusted by universities, startups, and enterprise clients.
• Nationwide Economic Impact: Enabling local innovation with global reach.
• A Focus on Renewable Energy: BUZZ HPC bridges the gap between AI and renewable energy sources by fueling 100% of its datacenters with hydroelectric power.

Supporting Canada's AI Future

"BUZZ HPC delivers a sovereign AI solution rooted in Canada-with global capability," said Craig Tavares, President and COO. "We empower Canadian innovators while supporting international partners who share our vision for secure, scalable AI."

BUZZ HPC is already driving advancements in AI. Its next-generation infrastructure is a cornerstone of Canada's AI sovereignty and global competitiveness. Through its website, buzzhpc.ai, BUZZ HPC is now offering free and subsidized HPC credits to Canadian companies, research institutions, and startups to help reduce the financial and technical barriers to accessing cutting-edge computing power for AI.

BUZZ HPC: Canada's AI Cloud. Sovereign. Scalable. Ready.
