About
CVS Pharmacy is the largest pharmacy chain in the United States, operating approximately 9,000 retail pharmacy locations nationwide. Founded in 1963 and headquartered in Woonsocket, Rhode Island, CVS has grown from a regional drugstore chain into a healthcare mega-platform through decades of acquisitions and vertical integration. The retail pharmacy business — dispensing prescriptions, selling health and wellness products, and providing immunizations and clinical services — is the customer-facing foundation of a much larger healthcare enterprise that includes pharmacy benefit management and health insurance.\n\nCVS Pharmacy is the consumer brand within the broader CVS Health corporation, which also operates Caremark (one of the largest pharmacy benefit managers in the US, processing hundreds of millions of prescriptions annually) and Aetna (a major health insurer with tens of millions of members). This integration of retail pharmacy, PBM, and health insurance makes CVS Health one of the most vertically integrated healthcare companies in the world, with levers spanning drug dispensing, formulary management, and member health management across the full care continuum. CVS has also expanded into primary care through its MinuteClinics and the acquisition of Oak Street Health.\n\nIn 2026, CVS Pharmacy is actively expanding its pharmacy-only format — smaller footprint locations focused exclusively on prescription fulfillment and clinical pharmacy services, rather than the traditional front-end retail merchandise mix. This format evolution reflects a strategic pivot toward healthcare services as retail foot traffic shifts to e-commerce. CVS Health reported approximately $372B in total revenue, reflecting its scale across all business segments. The company faces ongoing margin pressure from drug pricing dynamics and PBM reform discussions, but its integrated model and massive national footprint make it a structurally important player in US healthcare delivery.
