BB&T and SunTrust Banks said Wednesday that when their planned merger is completed, their new name will be "Truist." The banks said they worked with Omnicom unit Interbrand to come up with the new name after "focus groups and analytical research" from bank employees and clients. According to the banks, the combined firm, Truist Financial Corp., will be the sixth-largest bank holding company in the U.S. The merger is expected to complete in the third or fourth quarter of 2019, the banks said.
