Strengthening the Software Layer of its

Vertically Integrated AI Cloud Platform

NEW YORK, August 4, 2026 (GLOBE NEWSWIRE) – IREN Limited (NASDAQ: IREN) (“IREN”) today announced it has completed the acquisition of

Mirantis, Inc. (“Mirantis”), a leading provider of cloud software and services, through the issuance of approximately 12.6m ordinary shares, fixed at signing, plus cash, restricted stock units and other consideration of approximately $40m as of closing.

The acquisition deepens IREN’s capabilities across AI workload orchestration, monitoring and customer support, further strengthening its vertically integrated AI Cloud platform spanning owned and operated data centers, compute and software.

The acquisition also supports IREN’s strategy to serve a large and diverse customer base over time, including hyperscalers, enterprises and

AI developers across bare metal and managed cloud services, and has already facilitated several of IREN’s announced and prospective AI Cloud contracts.

Mirantis brings deep software engineering and technical expertise, and a track record of serving more than 1,500 enterprise customers globally. Mirantis is an inaugural partner of the NVIDIA AI Cloud Ready Initiative, and has integrated k0rdent AI with NVIDIA DSX OS software components, supporting current and next-generation NVIDIA architectures. The open-source k0rdent AI platform will continue to be developed and supported for Mirantis’ customers.

The combination brings together IREN’s owned and operated data centers and compute with Mirantis’ flexible, interoperable software layer, giving customers greater choice and control in how they deploy and scale AI workloads.

Daniel Roberts, Co-Founder and Co-CEO of IREN, commented:

“From the beginning our view has been simple: own the land and power, build the data centers, deliver the compute. Mirantis adds the software layer on top, turning infrastructure into a platform. That’s what lets us serve everyone from hyperscalers running bare metal to enterprises who want fully managed AI cloud.”

Alex Freedland, Founder and CEO of Mirantis, commented:

“For more than a decade, Mirantis has helped enterprises deploy and operate mission-critical cloud infrastructure software, and that commitment to our customers remains unchanged. Becoming part of IREN gives us the opportunity to bring those capabilities to an even larger infrastructure platform, accelerating innovation while continuing to invest in the open and infrastructure-agnostic k0rdent AI platform.”
