Microsoft tightens NeoCloud cooperation and exits Nscale UK project
Microsoft has withdrawn from its cooperation agreement with Nscale at the Loughton data center in Essex, UK. According to Reuters and multiple media reports, the decision stems from delays in grid connections, and local power supply is not expected to arrive until the 2030s. A Microsoft spokesperson said the decision involves only a single site, and the company remains committed to its overall partnership with Nscale.
In Texas, Microsoft refused to exercise its expansion option with Nscale. The option would originally have allowed Microsoft to more than double the scale of computing power it leased at the Ward County site, with a potential value of tens of billions of dollars. The existing base contract remains valid, and Nscale said the decision had been made months earlier and would not affect the total amount of its disclosed contracts.
Bloomberg reported on November 5 that, affected by data center delays and cost issues, Microsoft is tightening oversight of NeoCloud projects such as Nebius, IREN and Nscale, and is abandoning some projects seen as high risk. IREN’s site in Childress, Texas, has had cabling problems, and there had previously been a generator fire and delays in hardware deliveries; the two sides revised the schedule last week, and project completion could be delayed by several weeks or months. IREN’s five-year contract with Microsoft is worth about $9.7 billion.

Microsoft previously signed large-scale compute leasing agreements with multiple NeoCloud providers to make up for capacity shortfalls in its own data centers. Nscale’s Loughton project in the UK lost Microsoft as an anchor customer because grid connection was pushed into the 2030s; the Texas project is a case where Microsoft gave up the expansion option while keeping the base contract. IREN’s $9.7 billion contract in Childress has been affected by cabling issues, equipment delivery problems and earlier incidents, and the two sides have already renegotiated the delivery schedule.
On the capital path, Microsoft is adjusting third-party capacity from a fast-expansion tool to a selective supplement. Company CFO Amy Hood has repeatedly mentioned on earnings calls that delays in third-party capacity deliveries have affected spending plans. Capital is partially flowing out of NeoCloud projects that rely heavily on a single large customer and toward Microsoft’s own construction and more controllable leasing arrangements.
A comparable case is the valuation pullback in AI hardware after the tariff shock in April 2025, as well as the repricing of expectations for data center regulation after the recent midterm elections. The similarity is that policy and delivery uncertainty triggered a reassessment of high-valuation infrastructure assets; the difference is that the core constraints this time are power access, construction execution and costs, rather than simple demand disappearance.
This adjustment changes Microsoft’s pricing of its dependence on external capacity, rather than a wholesale cancellation of confirmed orders. Indicators to watch are the pace of Microsoft-related revenue recognition in subsequent NeoCloud financial reports, progress on grid and construction permits, and changes in the mix of self-built versus leased capacity in Microsoft’s capital expenditure guidance.

Delays in power access can directly cause an anchor customer to exit a single data center project, even if the overall partnership remains in place.
Not exercising an expansion option and terminating a base contract are different matters; the former does not automatically cancel the contracted capacity already signed.
Delays in third-party capacity delivery force large cloud providers to tighten oversight and readjust the proportion of self-built versus leased capacity.
