IREN August 2025 Monthly Update

NEW YORK, Sept. 08, 2025 (GLOBE NEWSWIRE) -- IREN Limited (NASDAQ: IREN) (together with its subsidiaries “IREN” or “the Company”) today published its monthly update for August 2025.

August Highlights

• AI Cloud expanding to 10.9k NVIDIA GPUs (>80% Blackwells), supported by non-dilutive GPU financing
• Expansion opportunity of >60k GPUs⁹ across British Columbia campuses, anchored by >20k at Prince George¹⁰
• NVIDIA Preferred Partner status secured
• Liquid-cooling installation at Prince George for GB300 NVL72 deployments

Management Commentary

“Demand for our AI Cloud is accelerating as we prepare for the delivery of approximately 9,000 NVIDIA Blackwell GPUs over the coming months,” said Daniel Roberts, Co-Founder and Co-CEO of IREN.

“At Prince George, retrofits to support this expansion are progressing to schedule, with construction of a new liquid-cooled data center for NVIDIA GB300 NVL72 systems well underway. Following record fiscal year and quarterly earnings, we delivered another month of solid performance, generating $53m of hardware profit in August despite seasonal curtailment and electricity prices.”

Technical Commentary

AI Cloud

• NVIDIA Preferred Partner status secured – supporting ongoing customer expansion and diversification, with current fleet deployed across leading AI ecosystem partners including Together AI, Hume, and Fluidstack
• 10.9k GPU expansion underway – scaling from 1.9k to 10.9k NVIDIA GPUs, including ~9k Blackwell GPUs scheduled for delivery at Prince George over the coming months (targeting $200-250m annualized revenue by Dec 2025⁷)
• Capital-efficient growth through GPU financing – ~$200m of non-dilutive GPU financing secured, representing 100% of the purchase price of the underlying GPUs, with additional financing workstreams ongoing
• Customer pipeline progressing – active engagement with hyperscaler and non-hyperscaler customers across the full site portfolio, spanning powered shells, turnkey colocation, and cloud services

Bitcoin Mining

• Robust hardware profits – delivered >$1.6m in average daily hardware profits³ in August despite elevated summer electricity costs and lower average operating hashrate in part due to seasonal curtailment and planned site outages, including for BC Hydro line upgrade and energization of the second bulk substation at Childress

Assumptions and Notes

1. Total net electricity costs are presented on a net basis and calculated as GAAP electricity charges, demand response program revenue and demand response fees. Figures are based on current internal estimates and exclude Renewable Energy Certificate (“REC”) purchases.
2. Net electricity costs per Bitcoin mined is calculated as Net electricity costs for Bitcoin mining divided by Bitcoin mined.
3. Hardware profit is calculated as revenue less net electricity costs. Average daily hardware profit reflects total monthly Bitcoin mining hardware profit divided by the number of days in the applicable period. Hardware profit is a non-GAAP financial measure and is provided in addition to, and not as a substitute for, measures of financial performance prepared in accordance with GAAP. Refer to the Forward-Looking Statements disclaimer.
4. 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).
5. Hardware profit margin for Bitcoin Mining and AI Cloud is calculated as revenue less net electricity costs, divided by revenue (for each respective revenue stream) and excludes all other costs.
6. AI Cloud annualized revenue reflects weighted average price per GPU hour (including storage and ancillaries) for contracted GPUs as of August 31, 2025, multiplied 8,760 hours per year.
7. AI Cloud annualized revenue is presented as an illustrative measure of potential revenue based on a 10.9k GPU deployment. It is not fully contracted, there can be no assurance that it will be achieved, and actual revenue may differ materially. Assumes on time delivery and commissioning of GPUs.
8. Bitcoin Mining annualized revenue of >$1bn is presented as an illustrative measure of potential revenue of 50EH/s mining capacity based on the following assumptions: Bitcoin price of $115k, hardware operates at 100% uptime, network hashrate of 928 EH/s, block reward of 3.125 Bitcoin and transaction fees of 0.1 Bitcoin per block. Source: CoinWarz Bitcoin Mining Calculator.
9. >60k Blackwell GPUs reflects internal estimate of capacity based on 160MW power capacity, 1.1 PUE across British Columbia sites and NVIDIA B200 reference architecture.
10. >20k Blackwell GPUs reflects internal estimate of capacity based on 50MW power capacity at Prince George, 1.1 PUE and NVIDIA B200 reference architecture.
11. >4.5k GB300s reflects internal estimate of capacity based on 10MW (IT load) power capacity at Prince George liquid-cooled data center.

Non-GAAP Financial Measures​

This investor update includes non-GAAP financial measures, including net electricity costs, net electricity costs per Bitcoin mined, hardware profit, hardware profit margin, Bitcoin Mining annualized revenue and AI Cloud annualized revenue. We provide these measures in addition to, and not as a substitute for, measures of financial performance prepared in accordance with GAAP. There are a number of limitations related to the use of non-GAAP 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 GAAP electricity charges, demand response program revenue and demand response fees. Figures are based on current internal estimates and excludes the cost of RECs. Net electricity costs per Bitcoin mined is calculated as Net electricity costs for Bitcoin mining divided by Bitcoin mined. Hardware Profit is calculated as revenue less net electricity costs (excludes all other site, overhead and REC costs). Hardware Profit Margin is calculated as revenue less net electricity costs divided by revenue (excludes all other site, overhead and REC costs).
