CVS Health to Split in Two, Separating Aetna and Caremark From 9,000 Pharmacies
CVS Health plans to split into two companies by 2028, separating Aetna and Caremark from its 9,000 pharmacies. The move aims to allow each business to pursue independent strategies, though the company denies regulatory pressure as the driver. CVS reported Q3 revenue of $108.4B, up 5.4% YoY, and raised its full-year earnings forecast. Shares fell 12.5% on the news.
