Cigna has officially confirmed that it will not pursue a merger with rival insurer Humana. This announcement follows recent reports suggesting that the two companies had renewed discussions regarding a potential combination. Cigna's decision comes as a relief to investors, with its stock rising by 7.6% in pre-market trading, while Humana's shares fell by 5.9%. The proposed merger, if it had proceeded, would have created a significant competitor in the health insurance market, potentially rivaling UnitedHealth Group. Cigna emphasized that it remains focused on its existing capital priorities.
