IREN Business Update

SYDNEY, Jan. 21, 2025 (GLOBE NEWSWIRE) — IREN Limited (NASDAQ: IREN) (together with its subsidiaries, “IREN” or “the Company”) today provided a business update.

Key highlights

• Announcement of $1bn at-the-market facility to support general corporate purposes, including:
• Expanding capacity to 57 EH/s by H2 2025, with 50 EH/s on track for H1 2025
• Initiating direct-to-chip liquid cooling systems in existing data centers to enable rapid scaling for cloud & colocation opportunities
• Advancing construction at Sweetwater, including a 1,400MW substation and electrical build-out targeted for energization in April 2026
• Progressing a multi-gigawatt data center development pipeline to further enhance IREN’s portfolio of scarce power and land resources
• Ongoing analysis and evaluation of diverse capital sources, focusing on an optimal mix of debt and equity

1. Upgrading target to 57 EH/s

IREN is excited to announce its expanded growth target, increasing capacity to 57 EH/s by H2 2025.

At a $100k Bitcoin price, the Company’s post-expansion operations support run-rate Illustrative Adjusted EBITDA of $716m at 50 EH/s and $826m at 57 EH/s.¹

This expansion is driven by the construction of the final 100MW (Phase 6) at Childress, completing the full 750MW data center project by the end of 2025.

We believe this additional growth will help enhance IREN’s robust operating cashflows and further reduce its already industry-leading production costs, supported by:

• Additional economies of scale, reducing unit costs of production through amortising overheads
• Operational excellence, optimizing uptime and profitability of Bitcoin mining production
• Low power costs of 2.8c/kWh at Childress, since successfully transitioning to spot pricing²
• Leading fleet efficiency of <15 J/TH, following exercise of previous S21 Pro miner purchase options for S21 Pro (11 EH/s) and latest-generation S21 XP (8 EH/s) miners

2. Liquid-cooling in existing data centers

IREN is advancing the design of direct-to-chip closed-loop liquid cooling systems across its existing data centers.

Bitcoin mining remains a core business for IREN. However, with the release of liquid-cooled NVIDIA Blackwell GPUs in 2025 and growing demand for scarce liquid-cooled data center capacity, IREN is exploring the potential opportunity to replace Bitcoin ASICs with liquid-cooled GPUs under cloud or colocation service contracts in some of its data centers.

Initial installations will be focused on Prince George and Childress, with additional design and planning underway to be able to accommodate advanced liquid-cooled GPUs across all IREN data centers (910MW by the end of 2025).

As part of this initiative, and to support ongoing dialogue with prospective customers, procurement is underway for key liquid-cooling infrastructure; including packaged chiller plant, chillers, dry coolers and coolant distribution units, as well as UPS and diesel generator back-up systems to enhance operational resilience.

3. 1,400MW Sweetwater data center project update

The Sweetwater data center project is a highly strategic asset for IREN, offering unique scale with 1,400MW of grid-connected power, scheduled for energization in April 2026.

Latest project construction progress includes:

• Substation procurement activities for key components ongoing; including transformers, circuit breakers, and ancillary electrical equipment, supporting the 1,400MW bulk substation (345kV/138kV) as well as primary substations (138kV/34.5kV)
• Engaged leading EPC contractor for substation design and construction commencing in early 2025
• General site-works commencing in coming weeks; including construction and installation of site access points, interior roads, office, warehousing, lay-down areas and security ahead of receiving materials, equipment and labour resources to build at scale
• Civil works commencing shortly, preparing the site for data center construction

IREN is actively exploring multiple monetization pathways, including Bitcoin mining and AI-related opportunities, with ongoing discussions with third-parties.

4. New development sites

IREN’s experienced internal data center development team continues to provide a competitive advantage, driving substantial value creation with no reliance on M&A for growth. This is increasingly critical as data center demand surges and grid-connection timelines lengthen.

The Company has received multiple proposals valuing assets in its development portfolio at many times its cost, underscoring the potential value in developing greenfield sites internally.

IREN remains focused on securing land and negotiating new grid-interconnection agreements to support additional development sites, further strengthening its position in the expanding data center landscape. With a multi-gigawatt development pipeline and a focus on large power capacity sites, IREN is well-positioned for future growth across a range of potential data center end use cases.
