Why CVS Health plans to split pharmacy and Aetna, Caremark

Key Points:

• CVS Health announced plans to split into two publicly traded companies by mid-2028, separating its retail pharmacy business from its insurance and pharmacy benefit manager (PBM) operations, Caremark.
• The decision follows a successful turnaround under CEO David Joyner, with CVS posting eight consecutive quarters of earnings beats and significant cost-cutting measures improving profitability and cash flow.
• CVS's retail pharmacy has stabilized and gained market share amid competitor closures, while Aetna and Caremark have improved performance despite regulatory challenges and high medical costs.
• The split aims to provide each business greater focus and flexibility, although concerns remain about preserving synergies and competitive advantages previously gained through vertical integration.
• Both new entities face ongoing risks, including regulatory scrutiny for Caremark, competitive pressures for retail pharmacy, and the need for Aetna to continue improving Medicare Advantage margins.
