IREN flags networking changes in Microsoft AI contract as cause of Texas data center delay

Highlights

IREN's $9.7 billion Childress data center project for Microsoft faces delays due to Microsoft-requested networking equipment changes to support advanced AI models.
IREN now expects to achieve its $4 billion operating annual recurring revenue target in January or February, missing its previous year-end goal.
Q2 revenue reached $228 million with a $263 million net loss, amid slowed expansion plans due to tougher financing and sector-wide project disruptions.

Project changes and revised revenue timing

As reported by Business Insider, IREN said a Microsoft-requested change to networking equipment delayed progress on its $9.7 billion data center project in Childress, which is being built in four phases under contract with Microsoft.

IREN co-CEO Daniel Roberts said on Thursday's earnings call that Microsoft requested relatively inexpensive modifications after the first building was delivered in August, to help support the latest AI models. He said the data centers are largely complete and the company is waiting for remaining equipment to arrive before finishing commissioning.

Roberts also said IREN and Microsoft maintain a strong relationship despite the setback. The revised timeline means the company now expects to hit its $4 billion operating annual recurring revenue target in January or February, later than its previous goal of year-end.

Pressure on neocloud expansion and investor sentiment

The delay adds to wider concerns around neocloud operators, which rent AI computing capacity to businesses and have been dealing with power constraints and construction disruptions. Microsoft said last week it spent $5 billion less than expected on AI infrastructure because of delays from third-party cloud providers, and research firm Aterio said satellite image analysis pointed to IREN and Nebius.

Roberts said IREN is also slowing its expansion plans because financing conditions have become more difficult, even as customer demand remains strong. IREN reported quarterly revenue of $228 million and a net loss of $263 million, while its shares fell sharply on Thursday before recovering in after-hours trading.

Neoclouds such as IREN remain an important part of Nvidia's customer ecosystem. They broaden Nvidia's reach beyond hyperscale cloud groups including Google, Amazon, and Microsoft, which are both major buyers of Nvidia chips and developers of competing hardware.

The rise of U.S. AI data center projects is running into a tougher reality of higher financing costs, construction delays, and power limitations. Our earlier article noted that only a minority of planned projects look truly credible, as expensive funding and missed deadlines can undermine long-term contract economics and weaken investor confidence. It also highlighted how grid constraints and local opposition are becoming additional bottlenecks for rapid capacity expansion.
