vertically integrated model financial
"reflects the agility of IREN’s vertically integrated model, which provides end-to-end control"
A vertically integrated model is a business structure in which a company controls multiple steps of its supply chain—such as raw materials, manufacturing, distribution and sales—rather than relying on outside suppliers or partners. For investors this matters because integration can lower costs, improve quality control and speed up delivery like a bakery that grows its own wheat and runs its own shops, but it also ties up capital and concentrates operational risk.
AI training and inference technical
"delivering data centers, compute and software for AI training and inference."
Training is the process of teaching a machine-learning system by feeding it lots of examples so it learns patterns, like a chef practicing a new recipe until it knows the steps. Inference is when the trained system uses what it learned to make predictions or decisions in real time, like the chef cooking a dish for a customer. Investors care because training drives upfront costs, data and infrastructure needs, and model quality, while inference determines day-to-day performance, scalability, revenue potential and ongoing operating costs and risks.

IREN Delivers Horizon 1 to Microsoft and Achieves NVIDIA Exemplar Cloud Status on GB300 NVL72
NEW YORK, August 13, 2026 (GLOBE NEWSWIRE) – IREN Limited (NASDAQ: IREN) (“IREN”) today announced that Horizon 1 has been delivered to
and accepted by Microsoft, and that IREN has achieved NVIDIA Exemplar Cloud status on NVIDIA GB300 NVL72.

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 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, 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.”
