IREN Limited (NASDAQ: IREN) delivered the quarter its strategic pivot was built for. AI Cloud revenue nearly tripled sequentially to $200 million, driving total revenue up 66% to $228 million as Horizon 1 entered service for Microsoft with NVIDIA Exemplar status. The headline number missed consensus by a rounding error — $228 million versus the $228.3 million estimate — but the composition tells a more important story.
The $200 million in AI Cloud revenue broke into $135 million of services and $65 million of lease revenue, the latter appearing for the first time this quarter. Gross margin held at 86%, flat with the prior quarter. That suggests the pricing discipline management has emphasised is holding even as scale ramps. Bitcoin Mining revenue fell to $28 million from $67 million, a predictable decline as the company reallocates power and capital toward AI infrastructure.
The more than $4 billion annualised run-rate revenue target, previously pegged at year-end 2026, is now targeted for January 2027 and may extend to February. Management blamed a customer-requested design change and supplier timing. Roughly one month. The company stresses the target remains fully contracted and fully funded. Still, the shift matters. IREN's valuation thesis rests on how fast it converts contracted ARR into recognised revenue. One month on a $4 billion target is not a crisis. It introduces a pattern worth watching if subsequent milestones drift.
Adjusted EBITDA reached $66 million, up from $19 million in the prior quarter, for a 29% margin. The GAAP net loss of $263 million looks severe. It includes $148 million in depreciation and amortisation, $106 million in stock-based compensation, and $28 million in unrealised losses on financial instruments. The balance sheet remains what separates IREN from most AI infrastructure plays: $20.6 billion in total assets, including $6 billion in data centre assets with 20-year useful lives, and $5.8 billion in cash and restricted cash. Net debt stood at $4.4 billion, up sharply from $216 million in the prior quarter, reflecting the heavy capex cycle — $5.1 billion in investing cash outflows during the quarter.
The revenue backlog grew 22% sequentially to $20.3 billion, with roughly two-thirds from investment-grade counterparties. That backlog includes remaining performance obligations, lease arrangements, and estimated future revenue under committed contracts. Not a GAAP measure, but it signals a contracting machine that is accelerating, not slowing. Post-quarter, IREN signed a five-year contract at approximately $22 million per IT-megawatt with 90% of GPU capex prepaid by the customer, plus a short-term contract at $40 million per IT-megawatt. The prepayment structure deserves attention. It shifts capital risk from IREN's balance sheet to the customer. If repeatable, that model could meaningfully reduce the equity dilution that has funded the buildout to date.
The $15 billion in remaining planned FY27 capex is expected to be met by $9 billion in cash and committed GPU financing and prepayments. The remaining $6 billion is subject to market conditions. That gap is the key risk. IREN has demonstrated access to capital markets — it raised $498 million in equity during the quarter and drew $2.36 billion from its financing facility — but the cost of that capital matters. The $73 million in finance expense this quarter, up from $24 million sequentially, reflects the growing debt burden.
Watch next quarter for three things: whether the January ARR target holds, whether customer prepayments become standard in new contracts rather than exceptions, and whether Bitcoin Mining revenue stabilises or keeps falling as more power shifts to AI. The pivot is working. Whether execution pace can keep the capital structure ahead of the capex curve — that is the question.
