China's Fosun International Ltd has upped its bid for Portugal's Espirito Santo Saude to 4.82 euros a share or 460.5 million euros in total, stepping up the battle over the hospital business of the indebted Espirito Santo family. Portugal's CMVM market regulator said late on Friday it registered the all-cash offer by conglomerate Fosun's Portuguese insurance unit Fidelidade, while also extending by a week to Oct. 10 a rival offer by Mexico's Grupo Angeles, the first to bid for ESS.
