Stonepeak and Columbia Capital to Acquire Berlin Data Center Operator IPB

BERLIN – LONDON – ALEXANDRIA – November 10, 2025 – Stonepeak, a leading alternative investment firm specializing in infrastructure and real assets, and Columbia Capital, an investment firm focused on the digital infrastructure, enterprise technology, and mobility sectors, today announced that they have entered into an agreement to acquire IPB Internet Provider in Berlin GmbH (“IPB” or the “Company”), a leading data center operator in Berlin.

IPB was a founding member of the Berlin Commercial Internet Exchange (“BCIX”) and established Berlin’s first carrier-neutral colocation data center in 2003, which now represents the primary interconnection hub in the emerging Berlin data center market. The Company operates two strategically located data centers with a track record of providing reliable and flexible infrastructure solutions to more than 200 customers.

“As land and power constraints in Europe’s Tier I data center markets persist, markets such as Berlin are becoming increasingly important,” said Andrew Thomas, Senior Managing Director at Stonepeak. “IPB is the primary connectivity hub in Berlin, well positioned to capitalize on cloud demand overflow to Tier II markets and the shift to AI inferencing. We’re excited to again partner with Columbia Capital, and to build on IPB’s strong foundation and support its next phase of growth.”

“IPB has maintained connectivity leadership in Berlin and also co-founded BCIX, the largest IXP in Berlin, and we believe its strategic importance to Berlin’s expanding digital ecosystem will only increase,” said Patrick Hendy, Partner at Columbia Capital. “We look forward to leveraging our experience scaling digital infrastructure businesses to support IPB on its growth journey.”

“Stonepeak and Columbia Capital are ideal partners for IPB as we embark on this next chapter,” said Steffen David, founder and Managing Director of IPB. “We are confident that their disciplined investment approach and combined digital infrastructure expertise, expansive industry relationships, and deep experience scaling data center businesses will enhance our customers’ experience and accelerate our vision for the business.”

The transaction is expected to close in the fourth quarter of 2025. Additional terms of the transaction were not disclosed. Latham & Watkins served as legal counsel to Stonepeak and Columbia Capital. Forvis Mazars served as legal counsel and financial advisor to IPB.
