Why is CVS Health stock sliding today?
CVS Health stock fell 0.9% premarket after Q3 2026 results showed $108.4B revenue (+5.4% Y/Y) and $2.09 adjusted EPS, beating estimates. The company plans to split its retail pharmacies from Aetna and Caremark by 2028. Despite raised full-year guidance, investors weighed execution risks and Aetna's Medicare Advantage rating decline. Broader market gains did not impact CVS's decline.
