Management Commentary “Our core Bitcoin mining operations remain strong and resilient. Despite market volatility, we expect our expansion to 50 EH/s over the next four months to generate substantial annualized operating cashflows of approximately $600m5 at current market economics.” said Daniel Roberts, IREN Co-Founder and Co-CEO. “We’re also seeing increased demand for our AI and HPC offerings. Our AI Cloud Service approached full utilization by month-end, driven by strong interest in NVIDIA H100/H200s and, looking ahead, next-generation air-cooled Blackwells. Horizon 1 development is progressing well, with strong customer interest, including single-tenant demand far exceeding its initial 75MW capacity. Customer workstreams are advancing through technical due diligence, pricing negotiations and letters of intent.” “Our financing and investing strategy remains flexible, with a continued focus on accretive capital deployment. We are actively assessing market conditions and exploring alternative capital sources, including project financing for AI colocation opportunities.” Technical Commentary • Strong and resilient margins, underpinned by low electricity costs and sector-leading fleet efficiency • At a lower Bitcoin price of $80k, annualized operating cashflows of ~$500m at 50 EH/s5 • Bitcoin production declined in February due to 10% less days in the month (28 days vs 31 days) • AI Cloud Services revenue increased 39% with new contract wins in February, fleet nearing full utilization at the end of February, with additional contracted revenue expected to materialize in March Events • Q2 FY25 Results Webcast Replay available here • Cantor Tech Conference New York, Mar 11, 2025 • Roth Investor Conference New York, Mar 17 - 18, 2025 • NVIDIA GTC San Jose, Mar 17 - 20, 2025 UNBC Career Fair, Prince George (Mar 2025)

Assumptions and Notes 1. Electricity costs are presented on a net basis and calculated as IFRS electricity charges, ERS revenue (included in other income) and ERS fees (included in other operating expenses). Figures are based on current internal estimates and exclude 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 Operating Cashflow = 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, $90k and $80k Bitcoin price scenarios, 800 EH/s global hashrate, $0.035/kWh electricity costs, 3.125 BTC block reward, 0.1 BTC transaction fees and 0.13% pool fees. 50 EH/s scenario: 765MW (power consumption), $104m (overheads), $16m (REC costs). Illustrative Operating Cashflow 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.
