CVS HEALTH (CVS)

The company’s reach extends well beyond its stores. Through Caremark, CVS operates one of the largest pharmacy benefit managers in the country, administering drug plans for employers, insurers, government programmes, and other clients. That business processes about 2 billion adjusted claims a year and plays a central role in formulary management, pharmacy networks, specialty drugs, and drug cost negotiation.

CVS also owns Aetna, a major health insurer serving about 27 million medical members. This gives the company exposure to commercial, Medicare, Medicaid, and other health plan markets. The addition of Oak Street Health expands CVS into value-based primary care, particularly for older patients, while other care assets support home-based and clinical services.

The investment case for CVS centres on whether it can use this integrated model to lower healthcare costs, improve patient engagement, and capture more spending across the healthcare chain. Its scale is a major advantage, but the company also operates in highly regulated and competitive markets where reimbursement pressure, drug pricing scrutiny, and execution across multiple business lines remain important factors.
