Port operator DP World was forced to handover its 60-percent holding in Adelaide's container terminal to Flinders Port after the Australian firm exercised its right to buy the stake, DP World said.

The stake sale was triggered by a transaction entered by the state-owned Dubai firm last year to sell 75-percent of its Australian operations to private equity firm Citi Infrastructure Investors (CII) for $1.5 billion.

Flinders, which owned the remaining 40 percent in the terminal, received the rights to acquire the DP World stake following that deal.

"Flinders Ports have remained insistent in exercising specific provisions in a shareholders agreement to acquire DP World Australia's shareholding in the joint venture," Ganesh Raj, managing director for DP World's Australian business said.

"This was not a negotiated transaction and the total enterprise value, in excess of $235 million, representing 12.3 times historic earnings was determined by an independent expert valuer," he said in a statement.

DP World Australia also operates container terminals in Brisbane, Sydney, Melbourne and Fremantle. (Reuters)
