Warburg Pincus-backed data centre operator Princeton Digital bags US$1.3 billion from Stonepeak

Warburg Pincus-backed Princeton Digital Group announced on Friday (Jul 18) that it secured US$1.3 billion in funding from Stonepeak, a New-York based alternative investment firm specialising in infrastructure and real assets.

Princeton Digital is a Singapore-headquartered data centre operator, with a portfolio of more than 1.1 gigawatts across 20 data centres in Singapore, Japan, India, Indonesia, China and Malaysia.

The news follows a recently announced US$1.2 billion debt financing, bringing the total capital raised by Princeton Digital in 2025 so far to US$2.5 billion.

The investment will aid Princeton Digital in its next phase of growth, including greenfield development and mergers and acquisitions, said the company. Warburg Pincus will remain as the data centre operator’s largest shareholder.

Rangu Salgame, chairman, chief executive and co-founder of Princeton Digital, said: “With this partnership, Princeton Digital is uniquely positioned to scale with speed, continue being the trusted provider to the world’s most demanding hyperscalers, and further consolidate its position as a market leader in the region.”

Stonepeak holds about US$73 billion of assets under management and has an office in Singapore.

Warburg Pincus, a founding investor in Princeton Digital, said it was a “strong validation” of the data centre operator’s long-term strategy.
