UnitedHealth Group is acquiring Empresas Banmédica, a company that runs medical clinics and sells health insurance in Chile, Colombia and Peru, for $2.8 billion. UnitedHealth already has a presence in South America — it bought Amil Participações, a large provider and health insurer in Brazil, in 2013.

Why it matters: UnitedHealth has become one of the largest companies in the U.S. by growing its insurance and data services businesses, and acquiring providers. But the conglomerate has had its eyes on privatized international health care markets for a long time. In 2016, Larry Renfro, the head of UnitedHealth's Optum companies, said health care data services could be a "$1 trillion global marketplace."
