The merger of German players Wintershall and Dea has been completed after all required regulatory approvals were received.
Wintershall was the oil and gas business unit of chemicals giant BASF, while Dea was owned by LetterOne, a Luxembourg-registered investment vehicle backed by Russian billionaire Mikhail Fridman. BASF will own 67% of the merged company, Wintershall Dea, with LetterOne holding the rest.
