Cigna Group is not pursuing a combination with rival Humana, the health insurer said on Monday, days after Donald Trump's re-election as U.S. president raised investor hopes that the reported merger may pass antitrust scrutiny.

Cigna won’t be pursuing a deal with Humana, the health insurer said Monday. In light of recent and persistent speculation, Cigna confirmed that it is not pursuing a combination with Humana, in a press release early Monday.

The two health insurance giants held talks about a deal last year, but Cigna walked away after the two companies failed to agree on a price.
