IREN Limited
From Bitcoin Miner to AI Infrastructure Powerhouse
Executive Summary
IREN Limited is an Australian-founded, Nasdaq-listed digital infrastructure company that has transformed from a pure-play Bitcoin miner into a diversified provider of renewable-powered data centers serving both cryptocurrency mining and AI cloud computing markets.
Founded: 2018 in Sydney, Australia
Listed: Nasdaq (IREN) since November 2021

Key Metrics
Company Overview
Founded in 2018 by brothers Daniel and Will Roberts in Sydney, Australia, IREN Limited has undergone a remarkable transformation from a specialized Bitcoin mining operation to a diversified digital infrastructure powerhouse. The company's strategic pivot toward AI cloud services, anchored by a landmark $1.07 billion contract with Microsoft, represents one of the most significant business model evolutions in the digital infrastructure sector.
The company's vertically integrated business model encompasses the complete data center value chain: from site development and electrical infrastructure ownership to facility construction and computing hardware deployment. This integration provides exceptional control over cost structure and operational performance, with net electricity costs of approximately $0.033 per kilowatt-hour at its Childress, Texas facility—among the lowest in the industry.
IREN's commitment to 100% renewable energy sourcing represents more than environmental stewardship; it's a structural cost advantage that resonates with enterprise customers increasingly requiring sustainable compute infrastructure. The company's evolution from Iris Energy to IREN in November 2024 symbolizes this transformation from pure-play miner to diversified technology infrastructure provider.
