Princeton Digital Group (PDG), a Singapore-based data center operator, has secured $1.3 billion investment from Stonepeak, a global alternative investment firm specializing in infrastructure and real assets.

In a statement, PDG announced on last Friday the signing of a definitive agreement with Stonepeak, in which the latter will make a preferred equity investment in PDG to support its continued expansion across Asia Pacific (APAC).

This investment follows PDG’s recently announced $1.2 billion debt financing.

Together, Stonepeak’s investment and the recent debt financing bring the total capital raised by PDG in 2025 to $2.5 billion across equity and debt, reinforcing the company’s position as a leading provider of hyperscale infrastructure in Asia.

Stonepeak’s long-term capital will support PDG’s next phase of growth, including both greenfield development and merger and acquisition (M&A), across both established and emerging Asia Pacific markets.

With a current portfolio of over 1.1 gigawatts across six countries, PDG is one of the region’s largest and fastest-growing data center platforms.

With marquee global investors — Warburg Pincus, Ontario Teachers’ Pension Plan, Mubadala, and now Stonepeak — PDG said it is uniquely positioned with long-term backing from some of the world’s most respected capital partners.

Warburg Pincus will continue to be PDG’s largest shareholder.

“This milestone investment from Stonepeak is a strong endorsement of PDG’s strategy, execution, and sustained value creation. Stonepeak shares our deep conviction in the unprecedented growth of artificial intelligence (AI) and cloud across Asia Pacific,

“With this partnership, PDG 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,” said Rangu Salgame, Chairman, Chief Executive Officer and Co-founder of PDG.

Meanwhile, Andrew Thomas, Senior Managing Director at Stonepeak, said PDG has established itself as one of the clear leaders among digital infrastructure platforms in the Asia Pacific region.

He said the company’s track record of execution, top-tier management team, and significant power bank in critical hub markets in APAC positions it well to serve the continued demand from hyperscalers and AI-driven platforms in the region.

“This investment is a quality fit for our Asia infrastructure strategy, and we look forward to partnering with PDG’s management team, Warburg Pincus and existing shareholders to propel the company’s next phase of growth,” he added.

Ellen Ng, Co-Head of Asia Real Estate at Warburg Pincus, said as a founding investor of PDG, they have always believed in the founders’ vision and exceptional execution capabilities and supported the company’s evolution into Asia’s preeminent data center platform.

“This latest investment by Stonepeak is a strong validation of PDG’s market leadership and long-term strategy,

“As PDG’s largest shareholder, we are excited to welcome a like-minded partner to help propel the company into its next phase of growth, supporting the surging demand for AI and cloud infrastructure across the region,” she added.

PDG is being advised by Goldman Sachs and J.P. Morgan, and Latham & Watkins as legal counsel.

Barclays is serving as financial advisor and Sidley Austin LLP is serving as legal counsel to Stonepeak.
