SYDNEY, June 30, 2025 (GLOBE NEWSWIRE) -- IREN Limited (NASDAQ:IREN) ("IREN") today announced it has reached its mid-year target of 50 EH/s installed self-mining capacity.

Daniel Roberts, Co-Founder and Co-CEO of IREN, commented:

"Reaching 50 EH/s is a defining milestone and a testament to our ability to rapidly deliver complex energy and data center infrastructure. In just 30 months, we've scaled organically ~50x to become one of the world's largest and most efficient Bitcoin miners.

With 50 EH/s of mining expansion complete, we're now turning to our next frontier, leveraging the same execution discipline to scale AI infrastructure across high-growth compute markets."

50 EH/s Milestone Achieved

The 50 EH/s milestone is anchored by our 750MW Childress site, now supporting 650MW of operating capacity and forming the foundation of our next phase of growth with Horizon 1, a 50MW liquid-cooled AI data center, set for delivery in Q4 2025.

Platform for Long-Term Value Creation

IREN's 50 EH/s platform combines scale, efficiency and financial resilience built to endure Bitcoin cycles and market volatility:

Low-cost production – $41k all-in cash cost per Bitcoin last quarter with further operating leverage expected, driven by 15 J/TH efficiency, scale, low-cost renewable energy and vertical integration.¹
Asymmetric upside and resilient cash flows – exposure to Bitcoin upside, with built-in downside protection from low-cost operations that can help mitigate the impact of market downturns by allowing for increased Bitcoin production as higher-cost peers exit.
Immediate revenue realization – daily Bitcoin sales avoid balance sheet exposure and tie performance to operations, not price speculation.
No near-term mining hardware capex – recent fleet refresh minimizes capital needs and maximises free cash flow.
Flexible capital structure – convertible notes remain only source of non-equity financing, preserving flexibility for the next phase of growth.

These fundamentals provide substantial capital and capacity to accelerate our AI strategy, delivering high-performance AI infrastructure for a new wave of compute demand.

Hardware Profit

Assumptions and Notes

$41k all-in cash cost per Bitcoin mined reflects all direct and indirect costs for the quarter ended March 31, 2025, including total net electricity costs and other costs (employee benefits expense, professional fees, site expenses, RECs and other operating expenses excluding one-off items), divided by the number of Bitcoin mined during the same period.
Illustrative Hardware Profit sensitivities reflect illustrative mining revenue less assumed net electricity costs across different Bitcoin price and network hashrate scenarios. Source: CoinWarz Bitcoin Mining Calculator. Illustrative calculations and inputs assume hardware operates at 100% uptime, 3.5c/kWh net electricity costs, 3.125 BTC block reward, 0.1 BTC transaction fees, 0.16% pool fees and 765MW power consumption. Illustrative Hardware Profit is for illustrative purposes only and should not be considered projections of IREN's operating performance. Inputs are based on assumptions, including historical information, which are likely to be different in the future and users should input their own assumptions. There is no assurance that any illustrative outputs will be achieved within the timeframes presented or at all, or that mining hardware will operate at 100% uptime. The above should be read strictly in conjunction with the forward-looking statements disclaimer in this press release.

Non-IFRS Financial Measures

This press release includes non-IFRS financial measures, including net electricity costs and illustrative annualized hardware profit. We provide these measures in addition to, and not as a substitute for, measures of financial performance prepared in accordance with IFRS. There are a number of limitations related to the use of non-IFRS financial measures. For example, other companies, including companies in our industry, may calculate these measures differently. The Company believes that these measures are important and supplement discussions and analysis of its results of operations and enhances an understanding of its operating performance.

Net electricity costs are calculated as our IFRS electricity charges, demand response program revenue (included in other income) and demand response fees (included in other operating expenses). Hardware Profit is calculated as revenue less net electricity costs (excludes all other site, overhead and REC costs).
