Bloomberg yesterday reported that Western Union (WU) is working with an adviser to potentially sell its business-to-business cross-border payments business, and that the unit could fetch $500M. Deutsche Bank analyst Ashish Sabadra believes FleetCor (FLT) could be a potential acquirer given the synergies with its Cambridge B2B cross-border payments. The analyst estimates an acquisition could be $1 accretive to earnings per share 12-18 months post acquisition close, depending on the terms of a deal and the margin potential. More importantly, the deal would significantly enhance FleetCor's market positioning in B2B cross-border payments, Sabadra tells investors in a research note. The analyst thinks a potential accretive acquisition could provide upside to 2019 estimates. He keeps a Buy rating on FleetCor.
