The announcement Tuesday comes several days after another federal judge rejected a tie-up between two other massive insurers. Blue Cross-Blue Shield carrier Anthem is attempting to buy Cigna for $48 billion. Anthem has vowed to appeal that decision.
Aetna, the nation’s third largest insurer, had announced its bid for Humana in 2015. The deal would have given Aetna the opportunity to significantly expand its presence in the fast-growing market for Medicare Advantage plans, privately run versions of the federal Medicare program for people who are over 65 or disabled.
But Aetna’s attempt to gobble up the nation’s fifth largest health insurer brought in the Department of Justice, which sued to block the deal last summer.
U.S. District Judge John Bates wrote in the decision last month that neither new competition nor plans to shed some of the combined company’s businesses would be enough to ease antitrust concerns. Federal regulation would likely be “insufficient to prevent the merged firm from raising prices or reducing benefits,” Bates ruled.
Aetna Chairman and CEO Mark Bertolini said in a company release Tuesday that “the current environment makes it too challenging to continue pursuing the transaction.”
Humana is entitled to a $1 billion breakup fee, which would amount to about $630 million after taxes. The Louisville, Kentucky, insurer says it will announce its 2017 forecast and provide an update on its strategic plan after markets close Tuesday.
Aetna is based in Hartford, Connecticut.
The two deals blocked in federal courts would have melded the nation’s five largest insurers into three, with UnitedHealth Group Inc. currently the biggest.
The insurers have argued that growing through acquisitions would allow them to better negotiate prices with pharmaceutical companies, hospitals and doctor groups that also are merging and growing larger. They also expect to cut expenses and add more customers, which helps them spread out the cost of investing in technology to manage and improve care.
Insurers have also said that combining would help them stabilize their business on the Affordable Care Act’s public insurance exchanges.
But the American Medical Association said last week, after the Anthem-Cigna deal was shot down, that a merger would have created a health care behemoth too large to regulate and with too much control over the lives of consumers.
