KKR currently owns about 14% of GDC while Singtel has a stake of more than 4%.
The rest of GDC is held by ST Telemedia, wholly owned by Temasek Holdings, which is also the controlling shareholder of Singtel.
According to Reuters, if successful, the deal would rank among Asia's biggest data centre transactions, with the boom in artificial intelligence creating soaring demand for digital infrastructure.
In a statement the following day, Singtel says that it regularly explores and reviews business opportunities, projects and proposals relating to its business and investments.
It acknowledges that as part of a consortium which it did not specify who the other partners are, it is having ongoing discussions in relation to STT GDC.
Nonetheless, there is no certainty that such discussions will lead to any definitive or binding agreement and that it will make the required disclosures when needed.
Singtel shares as at 9.11 am, trades at a record $4.73, up 5.11% for the day, extending year to date gain of 53.07%.
