Once UnitedHealth’s $12.8 billion acquisition closes, 75% of prescriptions filled in the U.S. will be in the hands of three players.
OptumRx, UnitedHealth’s drug benefit arm, covers about 30 million people, while Catamaran represents about 35 million. [I.e. the merged UNH-VTRX will cover 65M lives.] That compares with about 90 million people for Express Scripts and more than 65 million for CVS.
