In late 2025, Iren Limited emerged as one of the market’s top AI performers, delivering a 120% total return over a four-month span. The company’s pivot from pure-play utilities to a hybrid energy and AI-cloud provider catalyzed strong investor interest. Year-over-year revenues rose 45% in Q4 2025, driven by new AI hosting contracts and the repurposing of idle hydropower capacity into data-center operations. This rapid growth pushed Iren’s market capitalization past €3 billion, reflecting broad confidence in its growth trajectory.

Iren’s unique business model combines renewable power generation—hydro, wind and solar—with in-house AI compute infrastructure. This integration has enabled the company to achieve average power costs of €0.035 per kilowatt-hour, roughly one-third below industry averages in Western Europe. As a result, Iren’s gross margin on AI services climbed to 62% in Q4 2025, compared with 48% one year earlier. Management projects that expanding its solar capacity by an additional 150 MW in 2026 will further reduce unit costs and support continued margin expansion.

In December 2025, Iren sealed an agreement to provide AI-optimized cloud capacity to Microsoft under an 85% EBITDA margin structure. The multi-year deal covers up to 500 MW of computing capacity and includes performance-based bonus incentives tied to uptime and energy-efficiency targets. This partnership is expected to contribute €150 million in incremental EBITDA over the life of the contract, representing nearly 30% of Iren’s current annual EBITDA run rate. Analysts estimate the deal will lift Iren’s consolidated EBITDA margin to above 35% by mid-2026.
