Ownership Ban Pushes Insurer-Pharmacy Split

Do you trust large health companies to put patients ahead of profits?

CVS Health plans to separate its healthcare solutions business, which will keep the CVS Health name, from its retail pharmacy business, to be named CVS Pharmacy. The split is subject to regulatory requirements and is expected to be completed in the first half of 2028.

Why it matters

CVS Health Chairman and CEO David Joyner said the 'Break Up Big Medicine' bill, which would bar companies from owning both a health insurer and a pharmacy benefit manager, is one reason for the breakup, describing the move as made from a position of strength. For healthcare operators, the decision signals how regulatory pressure on vertically integrated care and pharmacy models can reshape corporate structure.

CVS Health reported third-quarter revenue of $108.399 billion, up 5.4% year over year, and raised its 2026 adjusted EPS guidance to at least $8.20 per share from the prior $7.90 to $8.10 range. Shares fell 12.53% to close at $79.96 on Wednesday, and the stub does not specify how the separation will be financed or how regulators will review it.

The players

CVS Health

A large integrated healthcare company spanning retail pharmacy, pharmacy benefit management, and health insurance, led by Chairman and CEO David Joyner.

Elizabeth Warren

A U.S. senator from Massachusetts who co-sponsored the 'Break Up Big Medicine' bill targeting companies that own both insurers and pharmacy benefit managers.

Josh Hawley

A U.S. senator from Missouri who co-sponsored the 'Break Up Big Medicine' bill with Elizabeth Warren.

Mark Cuban

An entrepreneur and investor known for his involvement in healthcare cost debates, who publicly questioned whether the split benefits patients.

The details

The company would divide its operations into two businesses: a healthcare solutions unit retaining the CVS Health name and a retail pharmacy unit renamed CVS Pharmacy. The separation remains subject to regulatory requirements before it can proceed. CVS Pharmacy is guided for a third year of growth into 2027, while the healthcare solutions business carries the parent company's brand and its guidance. Sen. Elizabeth Warren and Mark Cuban publicly questioned whether the split benefits patients.

Market Landscape

The planned split follows the proposed 'Break Up Big Medicine' bill, which would bar companies from owning both a health insurer and a pharmacy benefit manager. CVS is restructuring in response to that named legislative pressure rather than in a vacuum.

Operators in healthcare services, pharmacy, and pharmacy benefit management should track how the proposed ownership restriction and CVS's response affect partner and vendor relationships. Pharmacies and benefit managers that depend on integrated arrangements may need to reassess contracts before any separation takes effect.

The takeaway

Watch how the 'Break Up Big Medicine' bill advances and how regulators treat the separation, since both will determine whether vertically integrated healthcare models face structural limits. Operators should review any contracts tied to CVS's integrated arrangements and track the company's next quarterly results for signs of how the split is being financed.

What happens next

CVS Health expects to complete the separation of its healthcare solutions and retail pharmacy businesses in the first half of 2028, subject to regulatory requirements.
