KKR, Singtel Close S$6.6 Bn STT GDC Buyout as Expansion Pipeline Tops 1.7 GW

KKR and Singtel have seized absolute control of ST Telemedia Global Data Centres (STT GDC), buying out the remaining 82% stake for S$6.6 Bn and taking full ownership of the Singapore-headquartered operator just as its expansion pipeline accelerates across Asia.

The transaction values the business at an implied enterprise value of about S$13.8 Bn, including leverage and capital expenditure for committed projects. After completion, KKR holds 75% of STT GDC, with Singtel owning the remaining 25%.

The consortium is paying the S$6.6 Bn consideration in cash across two equal tranches and has secured about S$5 Bn of debt facilities for the acquisition and future capital expenditure.

Separately, DBS, OCBC and UOB confirmed they were among the mandated lead arrangers, bookrunners and sustainability-linked loan co-ordinators for the S$5 Bn facility. The financing is tied to STT GDC’s renewable energy targets and the proportion of green-certified data centres across its portfolio.

How a Minority Investment Turned into Control

The completion caps a two-year transition during which KKR and Singtel moved from financing STT GDC’s growth to owning the platform. They first invested S$1.75 Bn through redeemable preference shares and warrants in 2024, when ST Telemedia remained the majority shareholder. At the time, STT GDC had a development pipeline of about 1.4 GW. That pipeline has since grown to more than 1.7 GW, while the wider platform now commands around 2.3 GW of design capacity across 12 markets in the Asia-Pacific region, the UK and Europe.

A critical distinction remains between those metrics. Design capacity represents the scale STT GDC can potentially support across its portfolio. Conversely, much of the development pipeline still requires construction, customer commitments and capital before it becomes active operating capacity.

But recent deployments show that growth is moving beyond plans on paper.

In June, STT GDC advanced a development pipeline of more than 360 MW of AI-ready IT capacity at its Jakarta campus, opening one facility, topping out another and breaking ground on two more. Days earlier, it expanded its Indonesian financing platform to IDR 8.8 Tn (about $500 Mn) to support further campus development.

Singapore’s Economic Development Board and the Infocomm Media Development Authority also selected the operator on August 21 to develop an additional 50 MW of data centre capacity designed for AI and advanced-computing workloads.

That expansion is what shifts the economics of the acquisition. KKR and Singtel are not simply buying STT GDC’s existing facilities. A substantial part of the S$13.8 Bn valuation rests on the platform’s ability to convert a massive pipeline into contracted, revenue-producing capacity.

Singtel Scales Up Independently of Nxera

For Singtel, the deal substantially expands a digital infrastructure strategy it has already been building through its Nxera unit.

In its fiscal 2026 results released in May, Singtel noted that organic expansion and the pending STT GDC acquisition were repositioning the group as a global data centre player with about 2.8 GW of design capacity.

STT GDC will continue to operate independently from Nxera, preserving two separate platforms while giving Singtel exposure to a much broader geographic footprint. That matters because building equivalent scale organically would require years of land acquisition, power agreements, construction and customer development across multiple jurisdictions.

For KKR, the transaction deepens an existing Southeast Asian digital infrastructure strategy that includes investments in Nxera, the Philippine tower operator Pinnacle Towers and subsea cable services company OMS Group. The relevant point is not just the size of KKR’s infrastructure pool, but its willingness to keep committing capital to platforms whose ultimate value depends on years of expansion after the initial investment.

For founding shareholder ST Telemedia, the transaction completes an exit from a business it created in 2014 and expanded from Singapore into a multinational data centre platform.

The next phase carries a different risk profile. AI demand may be expanding rapidly, but development pipelines do not generate returns simply by getting larger. They require power allocations, construction capital and customers willing to commit to capacity as it comes online.

KKR and Singtel have now paid for control of that pipeline. The test post-closing is how quickly more than 1.7 GW of planned capacity can be turned into occupied infrastructure and cash flow.
