Madrid-based restaurant operator AmRest Holdings said on Monday it has decided to sell its KFC restaurant business in Russia to a different buyer after the owner of the franchise executed its rights to oppose a deal announced two months ago. AmRest, which is listed on the Warsaw and Madrid stock markets, said in December it would sell the business to Russian restaurant and entertainment company Almira, but KFC-owner Yum Brands Inc blocked the deal, with AmRest eventually selling to Russian franchise holder Smart Service Ltd.
