IREN delays some Microsoft AI deliveries and outlines a $15 billion spending plan
IREN reported results for the quarter ended September 30, 2026, and said some infrastructure deliveries for Microsoft were running late, according to Reuters, which carried the story on Investing.com. The company also laid out about $15 billion of capital spending for the rest of fiscal 2027. IREN linked the slip to a network design change that Microsoft asked for, along with supplier timing, and said the change carries no financial penalty. The shift pushed part of its target for more than $4 billion in annualized run-rate revenue from year-end 2026 to January 2027, with a possible slip to February.
Quarterly revenue rose 66% sequentially to $228 million, above the $221.28 million analyst average compiled by LSEG. AI cloud revenue more than doubled to $200 million from $71 million. Backlog grew 22% to $20.3 billion, with roughly two-thirds tied to investment-grade counterparties. IREN exited September with $1 billion in annualized run-rate revenue and expects about a quarter of that to be recognized in the December quarter.
The $15 billion plan splits into about $9 billion covered by cash, committed GPU financing and prepayments, and $6 billion that depends on financing and market conditions. Bloomberg reported the same day that Microsoft is tightening oversight of neocloud projects run by IREN, Nebius and Nscale, which Reuters also noted.
Why it matters
For founders renting compute, a contract with a large platform does not guarantee on-time capacity. Delivery dates belong in vendor evaluations alongside price per GPU hour, because a slip can delay revenue, financing and product launches at the same time. Capacity plans should include schedule buffers and a second provider qualified before it is needed.
For investors and suppliers, the risk sits in the gap between signed backlog and live, billable capacity. IREN's plan depends partly on financing that is subject to market conditions, so a weaker AI equity market or higher capital costs could slow builds. Companies selling GPUs, power, cooling or data center services should expect large buyers to demand tighter oversight and more control over design changes.
