Discussions are advanced but could still be delayed or even fall apart, the people said, asking not to be identified as the information is private. KKR and STT GDC declined to comment.
KKR & Co. is in talks to buy ST Telemedia Global Data Centres in a deal that could value the Asian digital infrastructure provider at more than US$5 billion ($6.41 billion), according to people familiar with the matter.
The US investment firm and ST Telemedia Pte could reach a deal in the coming weeks, the people said. KKR is already a backer in the closely held data centre company known as STT GDC with a 14.1% stake. At a more than US$5 billion valuation, the deal could be among the largest for KKR this year, according to data compiled by Bloomberg.
