Management Commentary

“The past month has marked several significant milestones for IREN. We delivered another month of record revenues, executed an oversubscribed convertible note offering, reached our self-mining target of 50 EH/s, transitioned to U.S. domestic issuer status, and more than doubled our AI Cloud business with the procurement of next-generation NVIDIA Blackwell GPUs,” said Daniel Roberts, Co-Founder and Co-CEO.

“With nearly 3GW of grid-connected power and deep infrastructure expertise, we’re uniquely positioned to deliver flexible solutions across the AI stack, including powered shells, build-to-suit facilities, turnkey colocation, and fully managed cloud services. IREN is at the forefront of two transformative technologies, Bitcoin and AI, owning and operating the compute infrastructure that powers both.”

Technical Commentary

Bitcoin Mining

Record monthly revenues – driven by higher Bitcoin prices that more than offset the decline in Bitcoin production due to the shorter month
Maintaining strong and resilient margins – underpinned by best-in-class efficiency (15 J/TH), low net electricity costs and energy market intelligence & algorithms (3.0c/kWh Childress net electricity cost in June)¹
50 EH/s installed – reached target self-mining capacity by month end, with further expansion paused to prioritize continued build-out of AI verticals ($827m illustrative annualized hardware profit at 50 EH/s)⁶

AI Cloud Services

Hopper GPUs near full utilization – supporting diverse customer mix on contract terms ranging from on-demand to 3 years, including through white-labelled compute with leading US AI cloud providers (generating annualized run-rate revenue of $28 million)⁷
Blackwell GPUs procured– 1.3k B200s & 1.1k B300s to be installed at Prince George over the coming months, lifting total fleet to 4.3k NVIDIA GPUs and unlocking next-gen training and inference at scale

AI Data Centers

Customer workstreams progressing – continued engagement across a range of structures such as powered shells, build-to-suit and turnkey colocation across our portfolio, including Childress 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

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.
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. 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.
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).
Hardware profit margin for Bitcoin Mining and AI Cloud Services is calculated as revenue less net electricity costs, divided by revenue (for each respective revenue stream) and excludes all other costs.
Illustrative Annualized Hardware Profit = illustrative annualized mining revenue less assumed net electricity costs. 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, 765MW power consumption, $105k Bitcoin price, 50 EH/s operating hashrate and 837 EH/s network hashrate. Illustrative Annualized 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.

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-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, illustrative annualized hardware profit and AI Cloud Services annualized run-rate 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). Illustrative Annualized Hardware Profit is calculated as illustrative annualized mining revenue less assumed net electricity costs (excludes all other site, overhead and REC costs). AI Cloud Services annualized run-rate revenue reflects contracted revenue for utilized GPUs.
