Iris Energy Limited (IREN) How It Makes Money

Iris Energy Limited generates its revenue through a dual-engine business model: primarily by earning Bitcoin from its large-scale, renewable energy-powered mining operations, and increasingly, by providing high-performance computing (HPC) cloud services for Artificial Intelligence (AI) workloads.

The company's strategy is to leverage its vertically integrated, low-cost data center infrastructure-built for energy-intensive Bitcoin mining-to pivot into the high-margin AI data center market, funding this expansion through its profitable core mining business.

Iris Energy Limited's Revenue Breakdown

For the fiscal year ended June 30, 2025, Iris Energy Limited reported total revenue of $501.0 million. The revenue mix is heavily skewed toward Bitcoin mining, but the AI Cloud segment is the clear growth driver for the near-term future.

Here's the quick math: Bitcoin Mining revenue was approximately $484.6 million for FY2025, which represented a 163% increase year-over-year. The nascent AI Cloud Services segment contributed approximately $16.4 million in revenue for the year, but its annualized revenue run-rate is projected to hit $200-250 million by December 2025, which tells you where the company is headed.

Business Economics

Iris Energy Limited's financial engine is built on two core economic advantages: access to exceptionally low-cost, 100% renewable energy and a strategic shift to high-margin AI compute services.

The company's vertical integration-owning the site, power infrastructure, and data centers-gives it significant control over its largest cost: electricity. For instance, the net electricity cost at its Childress, Texas site was around 3.3 cents/kWh in Q3 FY25, which is among the lowest for industrial-scale compute operations. This low-cost base is the foundation for the high-margin structure across both business lines.

• Bitcoin Mining Profitability: The low energy cost helps maintain a high hardware gross margin for Bitcoin mining, which was approximately 68% for the full fiscal year 2025. The all-in cash cost to mine one Bitcoin was around $41,000 in Q3 FY25, which is a strong competitive figure.
• AI Cloud Profitability: The AI Cloud Services segment, where the company rents out high-performance GPUs (like NVIDIA H100s) as a GPU-as-a-Service (GPUaaS) model, operates at an even higher margin. Hardware profit margins here exceeded 95% in Q3 FY25, because electricity is the only significant direct operating cost.
• Funding Mechanism: Iris Energy Limited employs a 'no-hodl' policy, selling the Bitcoin it mines daily. This generates consistent, strong operating cash flow-$53.7 million in Q2 FY25-which is then reinvested to self-fund the capital-intensive AI data center expansion, avoiding corporate debt and dilution.

You can see the strategic shift clearly in their Mission Statement, Vision, & Core Values of Iris Energy Limited (IREN).
