Obinna Chima Atlas Mara Limited, an international financial services company that was formed to undertake investment in targeted banks in Africa, is considering options for its stake in Union Bank Nigeria Plc after receiving takeover interest, Bloomberg reported. The initial approaches for Atlas Mara’s 49.97 per cent holding in the bank came from local lenders looking to expand in Africa’s biggest economy, the people said, asking not to be identified as deliberations are private. The firm is working with Rothschild & Co. and no final decision has been made on a potential sale or any other alternatives, they said. Representatives for Atlas Mara and Rothschild declined to comment.
