Orange (ORAN -0.1%) is thinking of selling its Dominican Republic mobile unit and is set to hire a bank to advise it on a deal, several sources tell Reuters. MorningStar's Allan Nichols thinks a sale could yield €675M-€900M ($880M-$1.18B) for Orange, which (like some other European telcos) is trying to exit non-core markets and pare its giant debt load (currently stands at $51.3B). Orange is estimated to have 38.4% of the Dominican mobile market, and America Movil (NYSE:AMX) 51.2%.
