CVS Health breakup may preserve vertical integration despite regulatory scrutiny

On November 4, 2026, CVS Health announced plans to split in the first half of 2028 into two separate entities: CVS Health, focused on healthcare solutions, and CVS Pharmacy, managing retail operations. While CEO David Joyner cited regulatory pressure and the Break Up Big Medicine Act as drivers, experts note the split preserves core vertical integration between insurer Aetna and PBM CVS Caremark, leaving potential conflicts of interest unaddressed.
