Executive Commentary
"Exponential AI consumption growth has fueled demand for compute capacity well beyond the available supply of infrastructure. IREN was built for this moment. Our 2026 capacity is largely sold out. We have broadened our customer base to include hyperscalers, enterprises, AI developers, and frontier labs. As our platform has scaled and our market position has strengthened, we have attracted leading customers and secured stronger pricing, more attractive contract terms and improved paybacks."
Daniel Roberts, Co-Founder & Co-CEO
"Over the past 12 months, we have secured circa $19 billion in funding. Nearly $16 billion across customer prepayments, GPU financing and convertible notes, alongside equity of approximately $3 billion. We feel well-placed to scale our fundraising efforts to support the rapid growth of the platform."

Strategic Positioning
1. Vertical Integration Across Data Center, Compute, and Software Layers
IREN’s ownership of the full AI cloud stack—from land, power, and data centers to GPUs and software services via Mirantis—creates a compounding value effect. Each layer enhances the value of the underlying assets and enables differentiated customer offerings. The recent NVIDIA certification of Mirantis’ hypervisor underscores the company’s software credibility, expanding addressable markets to smaller AI developers and enterprises requiring managed orchestration over bare metal compute.
2. Diversified and Expanding Customer Base with Long-Term Contracts
The company has deliberately broadened its customer mix beyond hyperscalers to include frontier AI labs and AI developers focused on real-world automation and robotics. Contract renewals and expansions from existing customers like Together AI and Fireworks AI demonstrate durable relationships. Recent multi-year contracts exceed $20 million revenue per megawatt of IT load, with active negotiations around $25 million per megawatt, reflecting strong pricing power supported by high prepayments funding 45 to 55 percent of GPU CapEx.
3. Capital-Efficient Financing Model Driving Scalable Growth
IREN has pioneered GPU financing as an asset class, raising $6.5 billion in the last three months at competitive rates across investment grade and sub-investment grade counterparties. Customer prepayments fund roughly half of GPU costs upfront, combined with 90 percent financing of GPU CapEx. This model creates a funding flywheel enabling data center CapEx to be financed with limited incremental equity, supported by an unencumbered portfolio of data centers and a growing asset base.
4. Scalable Modular Data Center Design and Site Optimization
IREN’s Horizon deployments use standardized designs and supply chains, incorporating lessons learned to accelerate construction and commissioning. The company is increasing revenue per megawatt through site optimization, including liquid-cooled GPU deployments that maximize power utilization without requiring new grid capacity. Tools like NVIDIA Max LPS enable running more compute within existing power envelopes, enhancing asset productivity.
5. Strategic Global Expansion with Multi-Gigawatt Pipeline
Beyond North America, IREN is expanding into Europe and Australia with acquisitions like Nostrum and new developments in Spain and South Australia. The company’s pipeline exceeds five gigawatts, with 0.3 GW targeted for 2026 delivery and 0.8 GW for 2027. This geographic diversification mitigates regional risks and taps into global AI compute demand, including sovereign AI considerations.
Key Considerations
IREN’s FY26 results highlight the company’s position at the nexus of a structural compute capacity shortage and a rapidly evolving capital markets environment.
