IREN Limited (NASDAQ: IREN) Q4 2025 Earnings Call | 08/28/2025
AI Summary
Financial Performance (FY24, Ended June 30, 2024)
Adjusted EBITDA: $54.7 million, up $53.3 million YoY, the highest in company history.
Bitcoin Mining Revenue: Increased from $75 million to $184 million, driven by a hash rate increase from 5.6 EH/s to 9.4 EH/s, mining 4,191 Bitcoins at an average realized price of $44,000 (+89% YoY).
AI Cloud Services Revenue: $3.1 million, launched in February 2024, with month-on-month growth.
Electricity Costs per Bitcoin Mined: Rose from $11,000 to $18,100 due to global hash rate growth and the April 2024 Bitcoin halving.
Operating Expenses: Increased from $38 million to $56 million, reflecting business growth, including $22 million in employee benefits, $8.7 million in site expenses (including renewable energy credits), $7 million in insurance, $6 million in professional fees, and $6.3 million for a Canadian non-refundable sales tax provision.
Depreciation: Rose from $30.9 million to $51 million due to Childress site commissioning and accelerated depreciation of S19J Pro miners for planned Q1 FY25 sale.
Cash Flows: Net cash increase of $336 million, ending with $404.6 million in cash. Operating cash flows of $53 million (including $184 million from Bitcoin liquidation), investing cash outflows of $499 million (Childress expansion, Bitmain miners, 816 Nvidia H100 GPUs), and financing inflows of $782 million from 121 million shares sold via ATM ($108.1 million) and ELOC ($12.9 million).
Balance Sheet: Total assets of $1.2 billion, equity at $1 billion, no external debt, and $223 million remaining on ATM facility.
Operational Highlights
Bitcoin Mining Capacity: Increased to 15 EH/s from 10.5 EH/s, with guidance reiterated for 20 EH/s by October 2025 and 30 EH/s by December 2025. Purchased 10 EH/s of Bitmain S21XP miners (13.5 J/TH efficiency), reducing fleet efficiency to 15 J/TH at 30 EH/s. Retained 20 EH/s miner options for 2025, targeting 50 EH/s.
Data Centers: Operating 300 MW, on track for 510 MW by December 2025. Shifted to 25 MW data center designs (from 20 MW), targeting 50 MW/month construction. Reduced build costs from $750,000/MW to $650,000/MW through optimized designs, supplier relationships, and internal IP (e.g., miner racking, filter banks).
Power and Land Portfolio: Secured 2.31 GW of grid-connected power, with 750 MW at Childress (350 MW to be commissioned by December 2025). Additional 1 GW global development pipeline in progress. Morgan Stanley engaged to evaluate AI data center opportunities for 1.4 GW West Texas site, with active NDA discussions.
Power Strategy (Childress): Transitioned to spot pricing from August 1, 2025, after a $7 million one-off hedge closeout cost. Achieved 3.1 cents/kWh in August (~$23,000/Bitcoin mined), down from 4.3 cents/kWh historical average, enhancing profitability through dynamic curtailment in ERCOT’s volatile market.
AI Cloud Services: Operating 816 Nvidia H100 GPUs with full utilization and month-on-month revenue/customer growth. Poolside contract extended to August 2025 but will roll off as they consolidate clusters; capacity to be redeployed swiftly. Launched GPU pilot at Childress (16 GPUs, ~$1 million) to test flexibility across jurisdictions. Strong pipeline with focus on customer creditworthiness, prepayments, and contract tenor (targeting 12+ months).
Sustainability: Committed to 100% renewable energy, supported by renewable energy credits (RECs).
Strategic and Market Insights
Bitcoin Mining Outlook: Positioned as a low-cost miner with strong margins at current Bitcoin prices (~$23,000/coin cost at Childress). Hash price at all-time lows; growth depends on Bitcoin price rallies. Global hash rate growth limited by power/land scarcity, reinforcing IREN’s advantage with 2.3 GW secured.
AI/HPC Opportunities: Flexible strategy to balance Bitcoin mining (controllable, accretive) with AI cloud/co-location. AI deals involve complex counterparty negotiations (e.g., technical specs, backup generation, liquid cooling). Childress and Canada sites offer low latency (sub-10ms in Texas, 20ms in Canada) and retrofit potential.
Power/Land Scarcity: Thesis of digital-real world dislocation drives aggressive site acquisition (low CapEx, high optionality). Expects increasing scarcity over 5–20 years, enhancing portfolio value.
Capital Allocation: Disciplined approach to GPU investments, prioritizing contracts with favorable risk-return (12–36 month paybacks, prepayments). Bitcoin mining funds growth, with AI/HPC expansion contingent on optimal deal structures.
Q&A Highlights
Bitcoin vs. AI Strategy: Bitcoin mining offers control and accretive growth, while AI/HPC involves complex counterparty deals. IREN prioritizes flexibility, pursuing both on-demand and long-term AI contracts without speculative overinvestment.
Site Acquisition: Continues to pursue gigawatts of power/land due to long-term scarcity, requiring minimal CapEx (e.g., $20,000–$30,000 land options) and leveraging internal team expertise.
HPC Team Hires: Investments in network engineers, AI sales, and commercial expertise to support AI/HPC growth without heavy speculative CapEx. Focus on proving operational credentials and securing favorable contracts.
GPU Pilot (Childress): Small-scale (16 GPUs) to test operational flexibility, with ~24–30 month payback expectations for H100s, adjusted for new tech (e.g., Blackwell GPUs).
Poolside Capacity: Post-August, capacity redeployment balances on-demand and long-term contracts, leveraging Poolside’s referrals to attract new customers.
Data Center Design: 25 MW designs are go-forward, not retroactive, optimizing density and cost. Larger designs under consideration but 25 MW sufficient for now.
Hash Price Outlook: Tied to Bitcoin price; IREN’s low-cost structure (~$23,000/coin) ensures profitability. Global hash rate growth constrained by power/land availability, favoring IREN’s 2.3 GW portfolio.
Bitmain T21 Issues: Manufacturing defects (heat sinks, assembly quality) affected ~1.5 EH/s, being replaced by Bitmain with resolution expected in months.
West Texas Site: Greenfield site in design phase, with energization nearing. Morgan Stanley process explores co-location/AI opportunities, with dynamic valuations reflecting market evolution.
About this video
IREN Limited reported strong fiscal year 2024 results, highlighting significant growth in Bitcoin mining capacity and expanding AI cloud services. The company increased its installed Bitcoin mining capacity to 15 exahashes and remains on track to reach 20 exahashes by September and 30 exahashes by the end of 2025, supported by new purchases of efficient Bitmain S21XPs miners. Operational data centers grew to 300 megawatts of energized and commissioned capacity, progressing toward a year-end target of 510 megawatts. Cost-saving measures reduced the cost per megawatt of data center construction to approximately $650,000 while increasing data center capacity per build. IREN’s AI cloud services, launched earlier in the year, demonstrated month-over-month revenue growth with an active client pipeline and ongoing expansion plans including a GPU pilot at Childress. The company’s strong revenue growth included Bitcoin mining revenue increasing significantly alongside an increase in average realized Bitcoin price and mined volumes. Key financial highlights included adjusted EBITDA of $54.7 million, up significantly year-over-year, and a robust free cash flow position supported by operating cash flows and equity raises. The balance sheet remains strong with no external debt and substantial cash reserves. Strategic focus remains on leveraging the secured portfolio of grid-connected power and land, enabling continued hyper-growth in mining capacity and AI infrastructure. The company is actively exploring monetization of its West Texas 1.4 gigawatt site for AI cloud deployments. Risks such as fluctuating electricity costs and hardware issues were managed effectively, while optimism remains high on future growth driven by digital world demand outpacing real-world infrastructure supply.
