IREN Acquires Mirantis in $625 Million All-Stock Deal, Accelerating AI Cloud Market Expansion

On May 5, 2026, Nasdaq-listed IREN (formerly Iris Energy) announced a definitive agreement to acquire Mirantis, a cloud infrastructure and Kubernetes specialist, for approximately $625 million. The acquisition will be an all-stock transaction, through which IREN has begun its leap beyond a simple data center operator to a vertically integrated AI cloud powerhouse.

Mirantis is a leader in OpenStack and Kubernetes, possessing software expertise in orchestrating complex cloud workloads. By combining Mirantis's software "brain" with its own large-scale GPU-accelerated infrastructure, IREN can provide customers with a more efficient and powerful AI computing environment.

This acquisition is a key step in IREN's transition from a bitcoin mining-centered business model to a high-performance computing (HPC) infrastructure provider. While IREN has focused on securing large-scale data center sites and power infrastructure, the Mirantis acquisition provides the sophisticated software layer to run on top of that hardware. Analysts evaluate the deal as valuing Mirantis at approximately 4-5 times its annual revenue.

This acquisition of Mirantis will be an opportunity for IREN to occupy a unique position in the next-generation AI infrastructure market. We are now ready to provide full-stack AI cloud services ranging from hardware to software orchestration.

Mirantis will operate as an independent subsidiary within IREN even after the acquisition. This is a strategic choice to maintain Mirantis's existing vast enterprise customer base and influence within the open-source community. Simultaneously, Mirantis's engineering team will serve as the core engine accelerating IREN's next-generation AI cloud deployment.

Technical Synergy through Kubernetes and OpenStack

Mirantis's core competency, Kubernetes-based orchestration, automates the complex resource allocation required for AI model training and inference. In particular, 'Mirantis OpenStack for Kubernetes (MOSK) 26.1', announced on March 26, 2026, is evaluated to have maximized high-performance workload operation efficiency by featuring an AI assistant, which is expected to create immediate synergy with IREN's GPU infrastructure.

• Acquisition Price: Approximately $625 million (via issuance of IREN common stock)
• Acquisition Target: 100% stake in Mirantis, Inc.
• Key Technologies: Kubernetes, OpenStack, Cloud-native infrastructure
• Operating Method: Operated as an independent subsidiary under IREN, continuing support for existing customers

The investment market responded immediately, evaluating this acquisition as a decisive move to increase IREN's future value. On Tuesday, May 5, 2026, IREN's stock price on the Nasdaq closed up about 1% immediately after the announcement. This reflects expectations that IREN will be able to prove long-term profitability by securing software competitiveness amid intensifying competition in the AI cloud market.

IREN's move represents a major industrial trend of bitcoin mining companies expanding into the AI cloud field. While competitors like CoreWeave and Bitdigital focus on infrastructure expansion, IREN chose a differentiated strategy of integrating the software stack through the Mirantis acquisition.

The company now possesses a full-stack solution for enterprise-grade AI services, moving beyond being a simple infrastructure provider. This is expected to contribute to IREN securing higher margins and increasing customer retention as demand for AI model training grows. Mirantis's technology is expected to play a key role in positioning IREN as a leader in the Neocloud market.

Alex Freedland, co-founder of Mirantis, emphasized that this merger will be a significant milestone opening a new chapter in Mirantis's technological journey. IREN plans to leverage Mirantis's open-source expertise to build a more open and flexible AI infrastructure ecosystem. This could be an attractive alternative for enterprise customers seeking to avoid vendor lock-in.

Consequently, through this acquisition, IREN has completely shed its past identity as 'Iris Energy' and has been reborn as a true AI technology company. IREN's new platform, combining hardware infrastructure and software orchestration, is expected to further solidify its market position by absorbing the surging demand for enterprise AI.
