UnitedHealth Group has approached Aetna about a takeover deal within the past few days, according toThe Wall Street Journal.
The takeover deal would likely be valued at more than $40 billion, according to The Wall Street Journal, which relied on information from people familiar with the matter. It is still unclear whether Aetna has responded to UnitedHealth's takeover proposal.
This news is the latest in the merger frenzy talks that are going on in the health insurance sector. Within the last two weeks Anthem has made two takeover bids for Cigna, and Cigna has rejected both of them. Humana has also entered into takeover talks with both Cigna and Aetna.
