SYDNEY, Australia, June 20, 2023 (GLOBE NEWSWIRE) -- Iris Energy Limited (NASDAQ: IREN) (together with its subsidiaries, “Iris Energy”, “the Company” or “the Group”), a leading owner and operator of institutional-grade, highly efficient Bitcoin mining data centers powered by 100% renewable energy, today announced its expansion plan to 9.1 EH/s and revitalization of its high-performance computing (“HPC”) data center strategy, and provided a limited recourse equipment financing update.

Key Highlights

  • Childress Phase 1 (first 100MW): construction of remaining 80MW underway, targeting expansion of data center capacity from 5.6 EH/s to ~9.1 EH/s1 by early 20242

  • Childress Phase 2 (second 100MW): long-lead items ordered to unlock ~13.6 EH/s1

  • Near-term focus on data center construction, retaining flexibility on timing for miner purchases

  • Prior HPC3 data center strategy revitalized with early traction for potential use of current sites, as well as additional global sites under development

Iris Energy is pleased to announce the construction of the remaining 80MW of data centers for Phase 1 (first 100MW) at its 600MW Childress site is underway. The additional 4 x 20MW data centers are expected to increase the Company’s potential operating capacity by ~63% (from 5.6 EH/s to 9.1 EH/s1) and is targeted for completion by early 20242.

Additional long-lead items also continue to be procured, including for Childress Phase 2 (second 100MW) which is expected to unlock ~13.6 EH/s1 of data center capacity.

Near-term focus remains on data center construction, whilst retaining flexibility on timing for miner purchases, which is subject to funding and market conditions. The Company remains well capitalized with ~$64m of cash4, no debt, operating cashflows from its existing 5.6 EH/s, as well as additional optionality from its committed equity facility.

The Company also advises that its previous HPC data center strategy is now a parallel focus. Significant time was invested in exploring the strategy ~3-4 years ago, including signing a strategic memorandum of understanding with Dell Technologies in March 2020 to test and develop potential data center solutions for energy intensive compute applications, including leveraging Dell Technologies’ HPC and artificial intelligence expertise. Developments continue to accelerate in the sector, including the growth of computing power and clean energy requirements. Recent discussions with market participants have further validated this previous work and that the time may be right to expand into this sector, utilizing Iris Energy’s four existing operating sites and/or its geographically diversified portfolio of additional global sites currently under development. The Company’s approach to 100% renewable energy has been a key focus for many prospective HPC counterparties.
