The numbers behind the delay
Start with the good news. IREN posted revenue of $228 million for the quarter, up 66% from the prior quarter.
That topped the $221 million average analyst estimate compiled by LSEG.
The quarter in question is IREN’s first quarter of fiscal 2027, covering the period ending September 30, 2026. The company reported results on November 5, 2026.
The engine of that growth was AI cloud. That segment brought in $200 million, a 182% jump from the previous quarter.
Bitcoin mining, the business IREN was built on, contributed $28 million. The company that used to sell hash power is now mostly selling GPU capacity.
Then there is the less flattering line. IREN recorded a net loss of $263 million for the quarter, a reminder that building data centers at this scale burns serious cash before it earns it back.
Microsoft, Childress and a $20.3 billion backlog
The delayed revenue target is tied up with IREN’s largest customer relationship. The company holds a $9.7 billion, five-year contract with Microsoft.
Phases of that deal at IREN’s Childress, Texas site are expected to begin delivering by December 2026. The stock fell 18-20% on November 5 on reported delays linked to Microsoft, which helps explain why investors were so jumpy heading into the print.
The postponement of the more than $4 billion annualized run-rate target has also been tied to design changes and supply issues.
The company’s revenue backlog, meanwhile, keeps growing. It stands at $20.3 billion, up 22% from the prior quarter.
Roughly two-thirds of that backlog comes from investment-grade clients.
From mining rigs to AI racks
IREN is one of several companies that began life as a Bitcoin miner and then discovered that its real asset was something else: power, land and data center capacity.
The pivot has clearly changed the company’s revenue mix. AI cloud revenue now dwarfs mining income, and the Microsoft contract signals that hyperscalers are willing to rent capacity from former crypto operators.
What this means for IREN and its investors
The core tension in this report is timing, not demand. IREN has a $20.3 billion backlog and a marquee Microsoft deal, yet the market punished it for a milestone sliding by a matter of months.
The $263 million net loss adds pressure. A company spending heavily on construction needs revenue to show up on time to justify that spending, and a delay to at least January stretches the period in which costs run ahead of income.
The detail that the delay came at a customer’s request cuts both ways. On one hand, it suggests the revenue has been postponed rather than lost. On the other, it highlights how much IREN’s near-term trajectory depends on decisions made by a small number of very large clients.
For the crypto mining sector, IREN is a useful case study. Mining revenue of $28 million is now a side business next to a $200 million AI cloud segment, showing how far a former miner can move once it lands hyperscaler contracts.
The key dates to watch are December 2026, when Childress phases for Microsoft are expected to start delivering, and January, the new floor for the more than $4 billion annualized revenue target.
