Warburg Pincus, which recently closed its eleventh fund on US$11.2 billion, will become the largest shareholder in the company. Delonex Energy intends to access opportunities in the East African Rift System, the Central African Rift System and coastal margins of East Africa, through farm-in and direct awards from host governments.
