IREN Limited Q4 2026 Earnings Call Summary

IREN Limited has undergone a strategic transformation from a mining-centric model to a vertically integrated AI cloud provider, owning the entire stack from data centers and power to GPUs and software. Management attributes the year's performance to the structural disconnect between near-instant digital demand scaling and the multi-year lead times required for physical infrastructure.

The company's competitive positioning centers on "scarcity value," where ownership of grid connections and power allows IREN to capture higher margins as compute demand outstrips supply. Management emphasizes that signing deals is no longer the bottleneck; the primary constraint is the speed of bringing physical GPU capacity online.

Recent operational milestones include the delivery of Horizon 1 to Microsoft, validating IREN's ability to integrate complex liquid-cooled hardware and software at scale. The acquisitions of Mirantis and Nostrum have provided the software orchestration layer and development pipeline necessary to serve a broader range of enterprise and frontier AI customers. Customer retention has emerged as a key proof point, with existing clients such as Together AI and Fireworks AI renewing and expanding their footprint on the platform.

For fiscal 2027, IREN is guiding toward $25 billion to $30 billion in CapEx to support delivery of contracted capacity and build-out of new liquid-cooled facilities. The company targets reaching 1.2 gigawatts of gross capacity by 2027, with 2026 capacity already largely sold out and active negotiations underway for 2027 and 2028 capacity. The funding framework relies on a "flywheel" effect where GPU financing and customer prepayments, covering approximately 50 percent of GPU CapEx, significantly reduce the need for external equity.

Revenue growth is expected to be driven by increasing revenue per megawatt, which has risen due to structural demand and the addition of managed services. IREN plans to decommission all remaining mining operations by December 2026 to fully reallocate power and infrastructure to AI cloud services.

The Q4 net loss of $684 million was primarily driven by $450.4 million in non-cash impairments related to the decommissioning of legacy mining hardware, alongside a $102.1 million decrease in the fair value of mining hardware held for sale. IREN maintains a cash position of $7.6 billion, though $1.7 billion is restricted, specifically set aside to fund the Microsoft GPU CapEx requirements. The company maintains 100 percent of its data center portfolio as unencumbered assets, providing a strategic reserve for future asset-backed financing.
