Deutsche Beteiligungs AG (DBAG) has sold two modern colocation data centres in Hamburg through its portfolio company Green Datahub. The buyer of both properties is an open-ended special AIF advised by Westend Real Assets GmbH. The company operates as a subsidiary of Westend Bank, which is owned by the Hopp family and specialises in real estate and real asset investments. The transaction has already closed, and the parties involved have agreed not to disclose the financial terms.
The operational continuity of both sites, named Alsterdorf and Rahlstedt, remains secured following the change of ownership. The IT firm akquinet, which forms part of the portfolio of DBAG-advised Fund VII, will continue to occupy and operate the data centres as a long-term tenant.
Development and new build under the holding
Green Datahub had been part of the DBAG portfolio since June 2022, when a majority stake was acquired via the "Long-Term Investments" strategy. This approach deploys financial resources directly from DBAG's balance sheet, granting greater temporal flexibility in terms of holding period and corporate expansion compared with traditional private equity fund structures. At the inception of the investment, the portfolio comprised solely the Alsterdorf data centre.
During the subsequent holding phase, the company delivered the new construction of the Rahlstedt facility. The project volume amounted to more than 60 million euros. DBAG supported the project across project financing, structural execution, and contractual arrangements, enabling construction to be completed within the planned schedule and budget.
Tom Alzin, Spokesman of the Board of Management of Deutsche Beteiligungs AG, noted that the concurrent acquisition of Green Datahub and akquinet via differentiated investment strategies provided a tailored solution for the vendors. He stated that the successful completion in Rahlstedt and the sale to a long-term infrastructure investor demonstrated the firm's execution strength in complex development projects. Through akquinet, DBAG also intends to maintain its commitment to Hamburg as a data centre hub.
Technical specifications and future capacity
Both Hamburg data centres meet high security and environmental standards. They achieve PUE values below 1.25 and satisfy the TÜV Nord Level 3 extended and Level 4 certification tiers. The fund managed by Westend Real Assets provides the properties with a long-term investment horizon and lays the groundwork for future capacity expansions.
