Neocloud operator IREN (NASDAQ: IREN) said on Wednesday that Horizon 1, the first of four 50MW critical IT deployments for Microsoft at its Childress, Texas campus, went from the start of civil works to an NVIDIA Exemplar Cloud-tested GB300 cluster in 14 months, 22% faster than industry benchmarks.
JLL estimates that a 50MW data center takes an average of 18 months to build globally. JLL's 2026 outlook also found 57% of data center projects ran at least three months late in 2025.
Horizon 1's delivery status to Microsoft was a point of recent controversy, with The Information reporting that Microsoft's lower than expected capex spends on data center leases were partially caused by IREN delays. Management cited a Microsoft request, made after the Horizon 1 handover, to reconfigure and upgrade the network across the full 200MW, along with supplier timing.

Revenue timing now rests on the other three phases, which together with Horizon 1 cover 200MW under a five-year, roughly $9.7 billion contract. IREN moved its target for more than $4 billion of operating ARR from year-end 2026 to January 2027, with a possible extension to the end of February.
As of November 5, Horizon 2 was built and Dell was commissioning it, Horizon 3 had all GPUs on site, and Horizon 4 GPUs were due within weeks. "We do not expect material revenue contribution from incremental Horizon and Mackenzie capacity, most of which will arrive late in December or early calendar year '27," CFO Anthony Lewis said. IREN expects to recognize one-quarter of its $1 billion September-exit operating ARR as December-quarter revenue, and Cantor cut its price target to $47 from $99 on the slip.
IREN's earnings release says revenue on each phase starts only after commissioning, testing and customer acceptance. Delays in those steps, including changes to customer technical requirements, can also lead to delay credits or other reductions in Microsoft's payments.

The GPUs are funded with $3.65 billion in financing and $1.94 billion in Microsoft prepayments. Management put remaining fiscal 2027 capex at about $15 billion against $9 billion of cash and undrawn commitments. Lewis named financing of the Horizon 1 through 4 data centers as a near-term priority.
