Actually, it has became so appealing that giant U.S. health insurer United Health Group, bought a 90% stake in Amil on its way to expand into Latin America in 2012, paying $4.9 billion in the process. More precisely, UHG bought 30% of the listed Amil from public shareholders and 60% from the Buenos. As part of the deal, the Buenos retained only 10% of Amil and Edson kept his position as Amil’s CEO. Thus, he became the first foreigner to join the board of United Health, as well as one of the largest individual shareholders of the group, with 0.8%.
