Investment manager DigitalBridge and Canadian pension fund La Caisse have completed their acquisition of Yondr, and appointed a new CEO for the hyperscale data center company.

The pair have assumed joint control of Yondr, having purchased the firm from previous owner Cathexis Holdings for an undisclosed sum.

As part of the deal, Aaron Wangenheim has been appointed as Yondr CEO, with Sandip Mahajan taking over as CFO.

Jon Mauck, senior managing director and head of data centers at DigitalBridge, said: “With a diverse global portfolio of campuses, Yondr further strengthens DigitalBridge’s world-class data center portfolio and reinforces our focus on being a global partner to the leading hyperscale, technology, and AI companies that are driving the digital economy.

“We look forward to working alongside Aaron and Sandip, who bring extensive leadership experience, as we support Yondr’s strategy of developing and operating scaled capacity to meet the demands of AI and cloud computing. We are also very pleased to partner again with La Caisse, who shares our partnership-oriented approach to long-term value creation.”

Digital Bridge’s plan to buy Yondr was first revealed last October, but the involvement of La Caisse, formerly known as CDPQ, was not announced at the time.

The two companies have worked together before. In 2019, La Caisse acquired a 30 percent stake in Vertical Bridge, the largest private owner and operator of communications infrastructure in the US and a DigitalBridge portfolio company. In 2024, DigitalBridge and La Caisse supported Vertical Bridge’s $3.3 billion tower transaction with Verizon.

London-headquartered Yondr is a developer, owner, and operator of data centers. At present, the company has a contracted capacity of 878MW, with 58MW currently operational. It also has projects in Virginia, the UK, Malaysia, Japan, Germany, and India.

Yondr has more than 420MW of capacity committed to hyperscalers, with “significant” additional land to support a total potential capacity of over 1GW, according to DigitalBridge.

Its next phase of growth will be overseen by Wangenheim, who has worked in the digital infrastructure industry for two decades, including a ten-year stint at T5 Data Centers in roles including chief operating officer.

“Yondr has an impressive track record as a leading developer, owner, and operator of hyperscale data centers,” said Wangenheim. “I look forward to leading Yondr through its next phase of growth with the backing of two world-class investors that appreciate the critical role we play in supporting our clients.”

Wangenheim succeeds Paul Cossell, who has been in charge at Yondr for two and a half years but is now retiring after a long career in data centers.
