IREN Limited (IREN) Q4 2025 Earnings Call Transcript

IREN Limited reported a "breakout" FY 2025, achieving record Q4 revenue of $187 million, 10x year-on-year EBITDA growth, and $177 million in net income, primarily driven by strong Bitcoin mining profitability with an all-in cost of $36,000 per Bitcoin mined versus a $99,000 realized price. Strategically, the company is aggressively expanding into AI infrastructure, with over 10,000 GPUs online or commissioning, backed by 100% non-dilutive, single-digit financing for new GPU purchases, targeting $200-$250 million in annualized AI revenue by December 2025. Key projects include the Horizon 1 liquid-cooled AI data center on schedule for Q4 2025, early works for Horizon 2, and the 2 GW Sweetwater hub on track for April 2026 energization, positioning IREN as a vertically integrated provider of high-density AI compute.

Analysis

IREN Limited reported a breakout fiscal year 2025, underscored by record Q4 revenue of $187 million and a tenfold increase in year-over-year EBITDA, culminating in a strong net income of $177 million. The primary driver of this financial performance is its highly profitable Bitcoin mining operation, which runs at 50 exahash and benefits from a low all-in cash cost of $36,000 per Bitcoin against a realized price of $99,000. This mining segment is generating over $1 billion in annualized revenue, providing substantial cash flow to fund a strategic and aggressive expansion into AI infrastructure. The company is rapidly scaling its AI cloud business, with over 10,000 GPUs, including next-generation NVIDIA GB300s, being deployed, targeting an annualized revenue run-rate of $200-$250 million by December 2025. This expansion is notably financed in a capital-efficient manner, with recent transactions funding 100% of new GPU purchases through non-dilutive, single-digit rate financing.

Operationally, IREN is advancing several large-scale data center projects to capture the surging demand for AI compute. The Horizon 1 liquid-cooled facility in Childress, Texas, remains on schedule for a Q4 2025 launch, and strong demand has prompted the commencement of early works for a second facility, Horizon 2. Together, these sites can support over 38,000 liquid-cooled GPUs. Furthermore, its flagship 2-gigawatt Sweetwater data center hub is on track for energization in April 2026. This vertical integration, from secured power grids to operating compute clusters, positions IREN to offer end-to-end services, eliminating third-party colocation fees and enabling faster deployment. The company's strategy focuses on capitalizing on the scarcity of power and high-density data centers, leveraging its status as an NVIDIA preferred partner to attract a broad range of customers for both bare-metal cloud services and potential large-scale colocation.

Key Decisions for Investors

• Investors should consider the company's dual-engine model, where highly profitable Bitcoin mining is effectively de-risking and funding a rapid, high-growth pivot into the AI infrastructure market, which presents a significant long-term value catalyst.
• Monitor the execution of key project milestones, particularly the on-time completion of the Horizon 1 data center in Q4 2025 and the achievement of the $200-$250 million AI revenue run-rate by year-end, as these are critical proof points for the company's AI strategy.
• While the current GPU expansion is favorably funded with 100% non-dilutive debt, it is prudent to evaluate the evolving capital structure as the company advances larger-scale projects like Sweetwater, which may require substantial project-level or corporate debt.
• Assess the company's flexibility in monetizing its data center capacity; the decision to pursue higher-margin direct AI cloud services versus securing long-term, lower-risk colocation contracts at sites like Horizon will be a key determinant of future risk-adjusted returns.
