NEW YORK, Aug. 13, 2026 (GLOBE NEWSWIRE) -- IREN Limited ( IREN ) today announced that Horizon 1 has been delivered to and accepted by Microsoft, and that IREN ( IREN ) has achieved NVIDIA Exemplar Cloud status on NVIDIA GB300 NVL72.

Horizon 1 is the first of four 50MW (IT load) direct-to-chip liquid cooled AI Cloud deployments scheduled for delivery to Microsoft at IREN’s Childress, Texas campus in 2026 under a five-year, $9.7bn cloud services contract announced in November 2025.

The rapid delivery of Horizon 1 to Microsoft reflects the agility of IREN’s vertically integrated model, which provides end-to-end control across design, engineering and construction of the data centers supporting its GPU deployments.

IREN’s Exemplar Cloud status was achieved following NVIDIA’s testing of its NVIDIA GB300 NVL72 deployment at Horizon 1. The designation demonstrates IREN’s ability to support demanding AI workloads with performance, reliability and scale.

IREN ( IREN ) continues to target a broader expansion to 480MW (gross) AI Cloud capacity in 2026 and 1.2GW (gross) AI Cloud capacity in 2027.

Daniel Roberts, Co-Founder and Co-CEO of IREN ( IREN ), said:

“Delivering Horizon 1 demonstrates the strength of our vertically integrated model and our ability to execute complex AI infrastructure projects at speed and scale.

I want to congratulate and thank the more than 3,000 people across our site team whose expertise, commitment and execution made this milestone possible.

We look forward to building on this momentum with Microsoft as we work to deliver Horizons 2-4 later this year.”
