U3S21EXPH to be first ASIC miner mass-commercialized by BITMAIN with direct liquid-to-chip cooling within U form factor

Hut 8 plans to deploy model in Q2 2025 through ~15 EH/s hosting deployment with potential transition to self-mining through purchase option

Miami, FL, Sept. 19, 2024 (GLOBE NEWSWIRE) -- Hut 8 Corp. (Nasdaq | TSX: HUT) ("Hut 8" or the "Company"), a leading, vertically integrated operator of large-scale energy infrastructure and one of North America's largest Bitcoin miners, today announced the expansion of its partnership with BITMAIN Technologies Ltd. ("BITMAIN"), the world's largest manufacturer of digital currency mining servers, with the launch of the U3S21EXPH, a next-generation ASIC miner. Hut 8 plans to deploy the model in Q2 2025 through a ~15 exahash per second ("EH/s") hosting agreement leveraging custom data center infrastructure developed in-house by Hut 8.

As part of its long-term, power-first strategy, Hut 8 continues to scale its compute layer across energy-intensive technologies, including both Bitcoin mining and AI compute, with the aim of maximizing returns on its portfolio of power assets and digital infrastructure. The launch and commercialization of the U3S21EXPH is a key milestone in executing this strategy in the Company's Bitcoin mining segment as it advances scaled opportunities in AI compute.

Revolutionizing ASIC Compute: U3S21EXPH

The U3S21EXPH will be the first ASIC miner mass-commercialized by BITMAIN to feature direct liquid-to-chip ("DLC") cooling within a U form factor. Capable of achieving up to 860 terahash at an efficiency of 13 joules per terahash, the model represents the culmination of an extensive miner-manufacturer partnership between Hut 8 and BITMAIN. Under the partnership, which spans technical and commercial innovation, Hut 8 supported BITMAIN in the development of the miner.

Key advancements:

• Technology: Introduces DLC cooling technology used in high-performance computing ("HPC") data centers to a rack-ready form factor for Bitcoin mining
• Engineering: Evolution from "shoebox" ASIC form factor incompatible with traditional data center rack architecture to "U" form factor compatible with HPC-style architecture that can be deployed at densities of up to ~180 kilowatts ("kW") per rack
• Procurement: Strong overlap in secondary components with HPC data centers, including racks and cooling systems required for DLC technology, driving the opportunity for greater supply chain synchronization across Bitcoin mining and HPC data centers
• Construction: Opportunity to apply construction expertise and capabilities across Bitcoin mining and HPC data centers

To fully harness the potential of the U3S21EXPH, Hut 8 has developed a custom design for Bitcoin mining data center infrastructure inspired by traditional rack-based architecture. This design will be leveraged to house the initial ~15 EH/s deployment at a density of up to ~180 kW per rack.

"Our partnership with BITMAIN has allowed us to advance our thinking on ASIC compute and create a more scalable model for data center design as we expand our footprint," said Asher Genoot, CEO of Hut 8. "The U3S21EXPH will be the first miner from BITMAIN broadly commercialized with DLC cooling within a U form factor, making it rack-ready like traditional data center hardware. This innovation bridges critical engineering gaps between Bitcoin mining and AI data center infrastructure in both form factor and cooling technology, and we believe this convergence will enable us to unlock significant synergies and flexibility going forward."

"Asher and Mike have been invaluable thought partners to BITMAIN since the early days of US Bitcoin Corp, where they demonstrated a unique focus on cost-efficient procurement and operations," said Irene Gao, Vice President of Mining of BITMAIN. "Hut 8's technical expertise, operating strength, and track record of innovation made this partnership a natural evolution of our relationship as we began the journey of developing next-generation ASIC technology. We are excited to deepen our relationship as we continue to define the future of mining."

Commercializing the U3S21EXPH

The U3S21EXPH will be commercialized through a creatively structured hosting agreement between Hut 8 and BITMAIN. The agreement features a favorable fixed hosting fee with an option for Hut 8 to purchase all or a portion of the hosted machines in up to three tranches at a fixed price within six months of energization of the relevant tranches.

The structure is designed to drive a superior risk-return profile for the acquisition of new machines for Hut 8's self-mining fleet by reducing upfront capital requirements, offering a lower cost of capital, and de-risking a potential purchase by allowing the Company to assess future market conditions before committing additional capital.

The initial agreement comprises ~15 EH/s and is expected to increase Hut 8's hashrate under management from 18.5 EH/s1 to ~33.5 EH/s. If Hut 8 were to execute the purchase option for the entirety of the ~15 EH/s hosting deployment, the Company's self-mining hashrate is expected to increase from 5.6 EH/s1,2 to ~20.6 EH/s.

"Our team worked closely with BITMAIN to implement an innovative structure to commercialize the U3S21EXPH before it became available to the broader market," said Genoot. "For Hut 8, the benefit of the structure is twofold: it protects our downside with a fixed-price hosting revenue stream, and it creates significant option value with a fixed-price purchase option. We believe this model represents a more thoughtful approach to capturing the lucrative economics offered by next-generation machines, reducing upfront capital requirements while we continue to pursue growth initiatives in AI infrastructure."

Notes:

1. Based on the Company's capacity as of August 31, 2024.
2. Includes 100% of deployed hashrate at the King Mountain site, which is owned by the King Mountain JV in which the Company has a 50% membership interested and a Fortune 200 renewable energy producer has the remaining 50% membership interest.
