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.

Vancouver, British Columbia--(Newsfile Corp. - August 19, 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 that on August 3 it had signed a preferred partnership with Bell Canada, the country's largest telecommunications provider¹, to deliver one of Canada's largest sovereign AI ecosystems through Bell AI Fabric.

BUZZ HPC will provide Bell's government and enterprise customers with access to NVIDIA Ampere, NVIDIA Hopper, and NVIDIA Blackwell GPU clusters, scalable over NVIDIA Quantum-2 InfiniBand networking. BUZZ HPC's large-scale NVIDIA accelerated computing infrastructure, purpose-built for AI, machine learning, and scientific computing, will be integrated with Bell AI Fabric's advanced fibre network, data centres, and partner ecosystem, including Cohere. This combined capability supports a range of use cases, including developing AI foundational models and fine-tuning existing models all within Canada.

By expanding accelerated computing infrastructure across multiple provinces, the collaboration ensures true nationwide reach. Canadian innovators will gain access to high performing NVIDIA accelerated computing, hosted in secure, Canadian-owned facilities that comply with strict data residency and cybersecurity regulations.

"Sovereign is the new standard for cloud computing, and this partnership with Bell marks the beginning of a new era for AI innovation in Canada, with NVIDIA-accelerated infrastructure deployed domestically and a global footprint serving international customers, we are uniquely positioned to help Canada lead in AI while protecting its digital independence."

- Frank Holmes, Executive Chairman, BUZZ HPC

"BUZZ and Bell are sovereign by design, built to protect privacy and deliver trusted performance for innovators of all kinds. As a sovereign AI provider and NVIDIA Cloud Partner, our integration with Bell AI Fabric ensures secure, scalable access to accelerated computing across Canada empowering innovators to build globally competitive AI while maintaining full control over their data."

- Craig Tavares, President and COO, BUZZ HPC

"BUZZ HPC is one of the few Canadian cloud service providers with a purpose-built AI cloud that has experience operating GPU clusters at scale. We are excited to partner with BUZZ HPC for its AI infrastructure solutions - an important layer in the Bell AI Fabric ecosystem delivering the advanced workloads our customers need in a sovereign, private and secure Canadian facility."

- John Watson, Group President, Business Markets, AI and Ateko, Bell

"Sovereign AI infrastructure provides Canada's industries with essential computing to grow productivity, foster innovation and create economic opportunities. BUZZ HPC's NVIDIA infrastructure provides a high-performance AI computing backbone to drive innovation through Bell AI Fabric."

- Dave Salvator, Director, Accelerated Computing, NVIDIA

Launching later this year, BUZZ HPC's infrastructure will begin with a 5 MW deployment in Manitoba, followed by expansion into other Bell AI Fabric data centres. These deployments are designed to support a wide range of national objectives:

• Secure, sovereign AI: Data and compute infrastructure remain entirely within Canadian-owned facilities, ensuring full compliance with national residency and privacy laws.

• Nationwide access to advanced AI tools: Cutting-edge NVIDIA accelerated computing and high-speed networking deployed across multiple provinces, starting with Manitoba.

• Enhanced innovation and competitiveness: Enables Canadian businesses, researchers, and governments to build world-class AI solutions locally while maintaining global competitiveness.

• Sustainable, scalable growth: Green energy-powered infrastructure designed for long-term expansion supports an eco-conscious path to AI development.

This partnership forms a comprehensive AI solution for the Bell AI Fabric ecosystem. BUZZ HPC provides the foundational hardware layer for large-scale AI workloads; Cohere delivers customized large language models; Ateko brings specialized professional services; and Bell offers Canada's most advanced network and data centre backbone all working together to accelerate Canada's leadership in artificial intelligence.
