The Maze: CVS Health plans to separate its U.S. drugstore and mail-order pharmacy business from its health insurance and prescription benefits operations. The plan would create two publicly traded companies. It would change who owns the pharmacies that fill prescriptions while keeping the insurer that pays for care and the business that manages drug coverage together. CVS expects to complete the separation in the first half of 2028 if the closing conditions are met.
The Details:
The stores and mail service go together. The proposed CVS Pharmacy would include about 9,000 stores, prescription delivery by mail, MinuteClinic walk-in and virtual care, and Health100, a consumer health technology service. The other company would retain Aetna, a U.S. health insurer, and Caremark, which manages drug coverage for health plans and helps determine which pharmacies members can use. CVS Specialty, which fills prescriptions for patients who need specialty medicines, would also stay on the healthcare side, alongside Oak Street Health’s primary care clinics and Signify Health’s home-based services. CVS acquired Caremark in 2007 and Aetna in 2018, when it pitched bringing insurance, pharmacy and local care together. The new plan redraws that boundary around retail and mail.
The same prescription can pass through both businesses. Under an existing option called Maintenance Choice, eligible Caremark members can fill a long-term prescription by mail or pick it up at a CVS store for the mail price. Caremark administers the benefit. The pharmacy fills the prescription. That relationship already shows up inside CVS’s accounts. The current Pharmacy & Consumer Wellness division recorded $32.2 billion in sales to other CVS units in the first nine months of 2026. That figure measures internal business across the current division. It cannot tell us what any future agreement between the new companies would be worth.
The separation has a timetable and unfinished work. CVS says the plan would let each company set its own investment priorities and give CVS Pharmacy room to seek more partners. Before the separation can close, CVS still needs final board approval, an effective registration filing with U.S. securities regulators and confirmation of the expected tax treatment, among other conditions. CVS says it will operate as one company through the transition. CEO David Joyner told investors the two companies would use commercial agreements to preserve services they built together. CVS has yet to publish the final terms that would determine where customers can fill prescriptions or how pharmacies get paid after the split.
MarketMaze Take: A pharmacy’s place in a health plan’s network can matter as much as its distance from the customer. The network determines which pharmacies can fill a prescription under that plan. CVS Pharmacy may be able to win more business from other plans after separating, while Caremark could still contract with CVS to keep some existing pickup and delivery options in place. The same ownership change could therefore widen the chain’s partnerships and preserve familiar routes for some customers.
The split also leaves Caremark and CVS Specialty together. U.S. Federal Trade Commission staff found that past dispensing patterns for certain generic specialty medicines suggested that large benefits managers might direct profitable prescriptions to their own pharmacies. That finding covers a narrower market than CVS’s store network, and the planned split leaves that ownership link in place. The clearest evidence of change will come from the agreements that determine which pharmacies can serve plan members and on what terms.
