Egypt-based investment bank EFG Hermes has said its merger deal with Qatari investment company QInvest is to lapse on May 3, unless it receives long-awaited approval from Egyptian regulators. If EFG does not receive a 'no objection' from the Egyptian Financial Supervisory Authority in the coming days, it will be difficult to implement the joint venture agreement. A spokesman for the authority said the deal was still being studied and that a decision would be announced at the right time, declining to give any details or time frame.
