Stellanor expands to 11 facilities with acquisition of AI-Ready data center from Imagination Technologies

Strategic sale-and-service-back agreement adds purpose-built facility supporting GPU and AI chip design workloads

London, UK – April 8, 2026 – Stellanor, the UK’s fastest-growing urban data center company, backed by DWS, today announced the acquisition of a purpose-built data center in Hemel Hempstead from Imagination Technologies, a global leader in graphics processing unit (GPU) and AI chip design. Under the sale-and-service-back arrangement, Imagination continues operating from the facility as a fully managed Stellanor client.

The acquisition brings Stellanor to 11 facilities across the UK with 39 MVA of secured grid capacity, demonstrating rapid platform expansion from two to eleven facilities in six months.

“This acquisition demonstrates the quality of infrastructure and tenants we’re attracting. Imagination Technologies is exactly the type of blue-chip technology company we are looking to serve.”

Stellanor Acquires and Serves Imagination Technologies

“This acquisition demonstrates the quality of infrastructure and tenants we’re attracting,” said Michael Tobin, Chairman of the Board, Stellanor. “Imagination Technologies is exactly the type of blue-chip technology company we are looking to serve – enterprises with demanding digital infrastructure requirements – from AI and high-performance computing to core enterprise applications and business-critical workloads – that need urban proximity and institutional-grade infrastructure. Their decision to continue operating from this facility as a Stellanor client reiterates our strategy to combine investment in growth and improvement of facilities with operational excellence to serve organizations where they actually operate. We’re building a differentiated platform in the UK market with the scale and capability to deliver AI-ready infrastructure around the corner from our clients’ operations. While AI is a fast-growing driver, the majority of enterprise demand continues to come from organisations seeking resilience, well connected infrastructure close to their operations.”

“As a global semiconductor IP company, our focus is on delivering high-performance, power-efficient GPU and AI technologies that enable our partners to build next-generation products,” says Markus Mosen, Chief Executive Officer of Imagination Technologies. “At the same time, maintaining operational resilience across our infrastructure is critical to supporting continuous innovation. Our partnership with Stellanor strengthens this foundation, ensuring we have the robust, scalable environments needed to support our teams while enabling us to remain agile and focused on advancing our core technologies.”

AI Meets Enterprise Infrastructure Demand

The Hemel Hempstead facility demonstrates the convergence of next-generation AI-ready infrastructure demand with the enduring needs of enterprise IT. While Imagination Technologies represents a leading-edge AI and semiconductor use case, the majority of organisations require similar levels of resilience, connectivity, and scalability to support a mix of traditional enterprise workloads, cloud environments, and increasingly, AI-driven applications.

“This acquisition sits at the intersection of two powerful trends: evolving AI growth and enduring demand for urban proximity,” said Aparna Narain, Partner at DWS. “It adds proven infrastructure serving a blue-chip technology tenant to Stellanor. We’re creating a differentiated category in the UK market – combining urban focus with the scale and financial capability to deliver high-performance, AI-ready infrastructure that supports the full range of enterprise requirements – from core IT to evolving digital and cloud workloads.”

Stellanor Expands to 11 UK Sites

Stellanor’s platform will comprise 11 data centers across the UK – including four locations within London, Reading, Cambridge, Woking, Gatwick and West Yorkshire in addition to the newly acquired Hemel Hempstead site. Following its September 2025 launch with two London facilities acquired from Colt Technology Services, the company is in the process of completing a second major acquisition: Redcentric’s eight UK data centers, expected to close in the coming months. The rapid expansion demonstrates both the commitment of DWS as our shareholder to building UK and Nordic data center infrastructure and strong market demand for enterprise colocation in urban centers. This growth reflects both rising demand from AI-driven use cases and sustained demand for secure, well-connected colocation infrastructure in urban locations.
