Amber Infrastructure is reportedly seeking a buyer for all of Australian data center firm iseek.

AFR reports it has seen a flyer inviting interested parties to buy the operator for AU$400 million ($266.5m). The Australian has also previously reported the company was looking to sell off the unit.

Prospective buyers have been told both Amber and iseek founder Jason Gomersall will entertain bids for the entirety of their stakes.

Amber Infrastructure bought a majority share in the company in 2021. Reports surfaced in March of this year that the investment firm was seeking a capital partner for iseek.

Aussie operator iseek has data centers in Brisbane, Northern Queensland, Sydney, and Adelaide.

iseek was founded in 1998, and by the time of the majority share acquisition was valued at around $150m.

Since then, the company has acquired Australian data center operator YourDC, including its data centers in Adelaide, in 2022. YourDC's founder Scott Hicks now leads the combined businesses, having taken over as CEO in February 2024.

Amber Infrastructure Group specializes in international infrastructure investments, such as digital infrastructure including fiber and data centers.

Amber also has a majority interest in Greenergy Data Centers, which has a data center in Estonia and plans to develop more locations across the Three Seas region.
