IREN Shares Fall 17% as Bitcoin Mining Revenue Drops 58% QoQ
IREN’s AI cloud business generated nearly 88% of quarterly revenue as Bitcoin mining income fell. The shift demands heavy investment, and the company has pushed back a growth target. Its shares fell 16.95% on November 5, 2026, though available information does not establish what drove the decline.
- Quarterly revenue reached $228 million, up 66% from the June quarter.
- AI cloud revenue rose to $200 million; Bitcoin mining revenue fell to $28 million.
- IREN now expects more than $4 billion in contracted ARR to be operational by January 2027, potentially February.
- The company expects $15 billion in remaining fiscal 2027 capital expenditure, including $6 billion dependent on targeted financing.
IREN’s November 5 earnings release, covering the three months ended September 30, shows how quickly its revenue mix is changing. AI cloud revenue jumped 182% from $71 million in the June quarter. Bitcoin mining revenue dropped 58%, from $67 million.
Those figures show revenue, not how much of IREN’s physical infrastructure has shifted from mining to AI. The company reported $135 million from AI cloud services and $65 million from cloud leasing. IREN has said its first Horizon deployment went into service for Microsoft, but it did not say how much leasing revenue came from that deployment.
AI revenue overtakes mining
Bitcoin miners use computing equipment to compete to add blocks to the Bitcoin blockchain. AI cloud providers sell access to computing capacity and related services. Miners’ power infrastructure and data-center experience can give them a head start, but adapting facilities for AI takes new equipment and infrastructure. Swapping one type of machine for another won’t do the job.
IREN reported a $263 million net loss, down from a $684 million loss in the prior quarter. Adjusted EBITDA, a non-GAAP measure of earnings before interest, taxes, depreciation and amortization, rose from $19 million to $66 million. The company defines the additional adjustments it makes to that measure. Neither adjusted EBITDA nor a segment margin should be mistaken for GAAP profit.
IREN reported an 86% gross margin for AI Cloud, unchanged from the prior quarter. The company’s measure excludes depreciation and amortization and is calculated before site-level costs, so it does not capture the business’s full costs. The company-wide net loss remains an important part of the picture.
Co-founder and co-CEO Daniel Roberts described the quarter’s milestones on the earnings call:
“This quarter Horizon 1 went into service for Microsoft with NVIDIA Exemplar status, AI Cloud revenue nearly tripled to $200 million, and operating ARR doubled to a billion.”
IREN cited NVIDIA Exemplar status for Horizon 1, but its materials do not explain the designation’s criteria. It is not a guarantee of performance or profitability.
Backlog and ARR are not cash in the bank
IREN reported a $20.3 billion revenue backlog as of September 30, up 22% from the prior quarter. About two-thirds was tied to investment-grade counterparties, meaning customers or other parties described as having investment-grade credit standing.
Backlog can signal demand, but it is neither revenue already earned nor cash already received. IREN’s calculation includes estimated amounts under committed contracts. Future revenue depends on delivery and service availability.
The company’s target of more than $4 billion in contracted annual recurring revenue (ARR) is also a forward-looking operating measure, not quarterly revenue. IREN calculates ARR using annualized pricing for commissioned GPUs under contract, along with assumptions about utilization and other services. The company says actual revenue may be materially lower.
IREN had targeted December 2026 for the more-than-$4 billion ARR goal. It now expects the associated 0.3-gigawatt (IT) program to be operational by January 31, 2027, with a possible extension to the end of February. An IT megawatt measures computing load, not a facility’s total power capacity.
Roberts said the schedule changed because of supplier timing and a design change requested by a customer. On the earnings call, he identified Microsoft as the customer seeking network-infrastructure changes for a 200-megawatt deployment. That is management’s explanation. Available information does not independently verify the cause of the delay.
The funding distinction matters
IREN says capital expenditure for the 0.3-gigawatt IT program supporting the more-than-$4 billion ARR target is funded, subject to financing conditions. That applies to this specific program, not the company’s broader spending plan.
Separately, IREN expects approximately $15 billion in remaining fiscal 2027 capital expenditure. It expects $9 billion to come from cash, committed financing and customer prepayments. The remaining $6 billion depends on targeted financing sources, including additional GPU and data-center financing, and is subject to market conditions. That money is not secured.
After the quarter, IREN said it had expanded an agreement with an unnamed AI research company through a five-year contract valued at approximately $22 million in annual revenue per IT megawatt. Roberts said the customer agreed to prepay 90% of the associated GPU capital expenditure. That prepayment covers the GPUs for this agreement, not IREN’s entire spending plan.
IREN also disclosed a shorter agreement valued at $40 million in annual revenue per IT megawatt. The company has not provided the deal’s full terms, duration or customer details. These per-megawatt figures reflect company-reported contract economics. They do not prove that all projected revenue has been delivered or recognized.
Construction is the next test
IREN reported $20.6 billion in total assets at September 30, including $6 billion in data-center assets. It said Horizon 2 through Horizon 4 were in late-stage construction, with more work underway at Childress, Mackenzie and Sweetwater. The Mackenzie development includes a 100-megawatt site.
Construction, commissioning and customer acceptance all affect when planned capacity can generate revenue. The delayed ARR target shows how supplier schedules and customer requirements can complicate a buildout, even when demand and contracts are in place. The financing-dependent portion of IREN’s broader capital plan also leaves the company exposed to market conditions.
IREN shares closed at $18.03 on November 5, down 16.95% from the previous session’s $21.71 close, according to market figures reported by crypto.news. The decline coincided with the earnings release and revised ARR timing, but that does not establish why investors sold.
IREN is part of a wider shift among Bitcoin miners seeking AI and high-performance computing customers. The opportunity is real: access to power and existing data-center operations may be valuable. But those advantages do not guarantee a quick transition, profitable contracts or easy financing. IREN’s rising AI revenue shows progress. Its loss, capital needs and construction schedule show the risks that remain.
