Princeton Digital Group (Warburg Pincus) data centers: 9 sites mapped

Princeton Digital Group is a Singapore-based data center operator set up in 2017 by the private equity firm Warburg Pincus, still its largest shareholder, with co-founders Rangu Salgame, its chief executive, and Varoon Raghavan. It says it operates more than 20 data centers in China, Singapore, India, Indonesia, Malaysia, South Korea and Japan, with a portfolio of more than 1.8 gigawatts. Other backers include the Ontario Teachers' Pension Plan, Abu Dhabi's Mubadala, and Stonepeak, which invested $1.3 billion in 2025.

The company borrows heavily to build. In March 2026 it said it would raise up to $5 billion in debt that year for facilities in India, Indonesia, Malaysia and Japan, starting with $350 million from a bank consortium. Chief executive Rangu Salgame told Bloomberg the loans rest on long customer contracts: "We have rock solid contracts with hyperscalers averaging 10 to 12 years." In April 2026 Bloomberg reported PDG had hired Goldman Sachs for a strategic review that could lead to a minority stake sale.

Its largest single campus is JH1 at Sedenak Tech Park in Kulai, Johor, Malaysia, about 70 kilometers north of Singapore. The first 52 megawatt phase opened in July 2024; by December 2025 PDG had topped out a third building and broken ground on a fourth, and said the campus would reach 200 megawatts, up from the 150 first announced. In Japan, PDG opened TY1 in Saitama City, near Tokyo, in April 2025: a $1 billion, 96 megawatt campus built by Lendlease, fed by a dedicated grid connection.
