CVS Split Could Push UnitedHealth Group To Sell Or Split Off Assets
CVS Health plans to split into two companies, separating its retail pharmacies and clinics from its Aetna health insurance and Caremark PBM unit. This move, driven by regulatory scrutiny, may pressure UnitedHealth Group and Cigna to sell or spin off assets. Analysts suggest such splits could mitigate regulatory pressures. CVS, UnitedHealth, and Cigna own major PBMs, controlling 80% of the U.S. prescription market.
