The United States Department of Justice (DOJ) has given the necessary approval of Cigna’s acquisition of pharmacy benefit manager (PBM) – Express Scripts. The $52 billion deal will result in a consolidated healthcare behemoth that some say, is in reaction to recent healthcare sector entrant – Amazon. Another large scale healthcare acquisition/merger – CVS/Caremark and Aetna – is currently under DOJ review, but is expected to be approved soon, in a $69 billion transaction. The Cigna/Express Scripts transaction is scheduled to be completed by the end of 2018.
