Source: GlobeNewswire (MIL-NZ-AU)

SYDNEY, June 05, 2025 (GLOBE NEWSWIRE) — IREN Limited (NASDAQ: IREN) (together with its subsidiaries, “IREN” or “the Company”), today published its monthly update for May 2025.

May Highlights

• Record monthly revenue and hardware profit
• $1.6m daily hardware profit in May
• On track for 50 EH/s by June 30
• AI Cloud Services revenue continuing to scale
• Horizon 1 AI Data Center on track for Q4 ’25 delivery
• Customer and financing workstreams progressing
• Transitioning to US domestic issuer status from July 1

Management Commentary

“Following record quarterly earnings reported earlier this month, we’re pleased to have delivered record revenue and hardware profit in May, underscoring the strength of our platform,” said Daniel Roberts, Co-Founder and Co-CEO.

“At the same time, we’re making strong progress across our AI verticals. At Childress, we’re executing on our Horizon 1 AI Data Center at pace. Subcontractors have been mobilized for the installation of the packaged chiller plant and our mechanical and piping contractors are fully onboarded with fabrication plans advancing. The project remains on track for delivery in Q4 2025, and we have confidence in contracting the capacity given ongoing customer engagement.”

Technical Commentary

Bitcoin Mining

• Record monthly revenues – driven by higher Bitcoin prices and increase in average operating hashrate, with record number of Bitcoin mined during the month
• Maintaining strong and resilient margins – higher electricity costs during the month offset by higher bitcoin prices (>70% monthly hardware profit margin YTD)
• 41 EH/s installed, on track for 50 EH/s by June 30 – remaining miners in the process of shipping from Southeast Asia (50 EH/s generates $977m annualized mining revenue at current mining economics⁵)

AI Cloud Services

• Revenues continuing to scale – fueled by ramp-up of existing agreements and newly secured contracts
• GPU fleet near full utilization – supporting training and inference workloads, including through white-labelled compute with leading US AI cloud providers (generating annualized run-rate revenue of $28 million⁶)

AI Data Centers

• Customer workstreams progressing – continued engagement across Horizon 1 and Sweetwater
• Procurement ongoing – continuing to secure long-lead equipment to enable rapid expansion of liquid cooled capacity at Childress beyond the initial 50MW Horizon 1 deployment

Assumptions and Notes

1. Electricity costs are presented on a net basis and calculated as IFRS electricity charges, demand response program revenue (included in other income) and demand response fees (included in other operating expenses). Figures are based on current internal estimates and exclude Renewable Energy Certificate (“REC”) purchases.
2. Hardware profit is calculated as revenue less electricity costs. Hardware profit is a non-IFRS financial measure and is provided in addition to, and not as a substitute for, measures of financial performance prepared in accordance with IFRS. Refer to the Forward-Looking Statements disclaimer.
3. Bitcoin and Bitcoin mined in this investor update are presented in accordance with our revenue recognition policy which is determined on a Bitcoin received basis (post deduction of mining pool fees).
4. Hardware profit margin for Bitcoin Mining and AI Cloud Services is calculated as revenue less electricity costs, divided by revenue (for each respective revenue stream) and excludes all other costs.
5. Illustrative Adj. EBITDA = illustrative mining revenue less assumed net electricity costs, overheads and REC costs, and does not include working capital movements. Source: CoinWarz Bitcoin Mining Calculator. Illustrative calculations and inputs assume hardware operates at 100% uptime, 909 EH/s global hashrate, $0.035/kWh electricity costs, 3.125 BTC block reward, 0.1 BTC transaction fees and 0.16% pool fees, 765MW (power consumption), $104m (overheads), $16m (REC costs), and $105k Bitcoin price.

The above should be read strictly in conjunction with the forward-looking statements disclaimer in this press release.
6. AI Cloud Services annualized run-rate revenue for utilized GPUs as of May 31, 2025.
7. Illustrative Adj. EBITDA sensitivities reflect assumptions for Illustrative Adj.

Preliminary Financial Information

The financial information presented in this investor update is not subject to the same closing procedures as our unaudited quarterly financial results and our audited annual financial results, and has not been reviewed or audited by our independent registered public accounting firm. The preliminary financial information included in this investor update does not represent a comprehensive statement of our financial results or financial position and should not be viewed as a substitute for unaudited financial statements prepared in accordance with International Financial Reporting Standards. Accordingly, you should not place undue reliance on the preliminary financial information included in this investor update.

Non-IFRS Financial Measures​

This investor update includes non-IFRS financial measures, including electricity costs (presented on a net basis), hardware profit and illustrative adjusted EBITDA. 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.​

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). Figures are based on current internal estimates and excludes the cost of RECs. Hardware Profit is calculated as revenue less electricity costs (excludes all other site, overhead and REC costs). Illustrative Adjusted EBITDA is calculated as illustrative mining revenue less assumed net electricity costs, overheads and REC costs, and does not include working capital movements.
