This latest step in the battle over Bumi comes as the company prepares for a general meeting on February 21.
Rothschild called for the meeting, where he wants shareholders to vote to remove 12 of the company’s 14 directors.
The Bumi board has proposed separating the company from the Bakrie Group and its stake in Bumi Resources and instead focus on its Berau, in which it holds an 85% stake.
Bumi PLC has a 29% stake in Bumi Resources. Last year it launched an investigation into “financial irregularities” at Bumi Resources.
The Bumi PLC board says separating from the Bakrie Group and Bumi Resources will be worth more than $580 million.
Berau is Indonesia’s fourth largest coal miner.
