Macquarie Infrastructure & Real Assets Inc. emerged as the preferred bidder for AirTrunk Pte Ltd., Bloomberg News reported, citing people with knowledge of the matter.

The Macquarie Group Ltd.'s infrastructure-investment affiliate is in the late stage of negotiations to buy the data center operator, which could be worth more than A$3 billion in a sale.

A shareholder group including AirTrunk CEO Robin Khuda, Goldman Sachs Group Inc.'s special situations arm and private equity firm TPG Sixth Street Partners was earlier reported to be seeking buyers for a stake in the company.

AirTrunk, which operates data centers in Sydney, Melbourne and Singapore, aims to launch a facility in Hong Kong in 2020.

Neither representatives for TPG Sixth Street nor Goldman Sachs commented on the matter, while a Macquarie representative did not immediately provide a comment, according to Bloomberg.
