Anthem acquiring Cigna in largest-ever health insurance deal: $54.2B. Anthem will acquire Cigna for $188 per share, the health insurance companies announced Friday. The deal, including Cigna’s debt, will be worth $54.2 billion. It is the largest-ever health insurance transaction, and part of the mass-scale merger race that is fundamentally changing the industry and fueling concerns over costs and competition. The definitive agreement comes a little more than a month after Indianapolis-based Anthem went public with an offer of $184 per share, which Bloomfield, Conn.-based Cigna rejected. The two sides had sharp disagreements over who would lead the combined company, which will have $115 billion in revenue if Anthem receives required approval from its sponsor, the Blue Cross and Blue Shield Association. The merger of Anthem and Cigna, expected to close in the second half of 2016, will bring the private health insurance market from five big players down to three. UnitedHealth Group will remain the largest by revenue, projecting $154 billion this year. However, Anthem will have a larger customer base. Anthem will have 53 million medical members, compared with UnitedHealth’s 46 million. The combined Aetna and Humana company, a deal announced earlier this month, will have 33.4 million health plan members and $115 billion in revenue. The Affordable Care Act has put pressure on health insurers to cut costs and improve care coordination, which analysts believe ignited the current firestorm of mergers and acquisitions.
