Cigna-Humana Merger Is Likely to Face Antitrust Challenge

From a financial perspective, a Cigna-Humana megamerger makes a lot of sense. 

Cigna has a huge pharmacy benefit management business, but has been largely missing out on the highly lucrative Medicare Advantage industry. Humana has the second largest Medicare Advantage business after UnitedHealth Group. Combining the two businesses would create a healthcare powerhouse that could go toe-to-toe with that industry behemoth.
