Catamaran Sails into OptumRx’s Harbor

As the free-standing pharmacy care business of UnitedHealth Group (NYSE: UNH), OptumRx has serious backing when the right target comes along. Last week, the right one came along in the form of Catamaran Corporation (NASDAQ: CTRX), the nation’s fourth-largest provider of pharmacy benefit management services and healthcare information technology solutions. The offer was $61.50 per share, or approximately $12.8 billion. The deal leaves No. 1 pharmacy benefits provider Express Scripts Holdings (NASDAQ: ESRX) as the last holdout in the field, and some analysts are cheering for a major pharmacy retail chain to make an offer. Don’t look at Rite Aid (NYSE: RAD), though. It just paid $2 billion for EnvisionRx in February.
