CVS Health (originally Consumer Value Stores) traces its roots to 1963, when brothers Stanley and Sidney Goldstein, along with partner Ralph Hoagland, opened a single discount health and beauty store in Lowell, Massachusetts. For its first few decades, the company was a relatively straightforward retail operation, growing steadily by acquiring smaller regional pharmacy chains. However, as the American healthcare system became increasingly complex and expensive, CVS realized that merely dispensing pills at the end of the supply chain was a low-margin, vulnerable business model.
The Caremark Acquisition
The turning point for the modern CVS occurred in 2007 with the roughly $26.5 billion merger with Caremark Rx. Caremark is a Pharmacy Benefit Manager (PBM). PBMs operate in the opaque, lucrative middleman layer of the pharmaceutical industry. When a corporation provides health insurance to its employees, it hires a PBM to negotiate bulk discounts (rebates) with drug manufacturers and dictate which pharmacies the employees are allowed to use. By acquiring Caremark, CVS gained leverage over the pharmaceutical industry and the ability to financially steer millions of patients directly into its own retail pharmacies, creating a profitable closed loop.
The Aetna Megadeal
Realizing that the physical retail store was under prominent threat from Amazon (which acquired PillPack and launched Amazon Pharmacy), CVS decided to double down on vertical integration. In 2018, the company executed a very large $69 billion acquisition of Aetna, one of the largest health insurance companies in the United States. This transformed CVS from a pharmacy chain into a full-fledged healthcare payer. The strategic logic was unprecedented: CVS now owns the insurance company that pays the medical bill, the PBM that prices the drugs, and the physical clinic (MinuteClinic) where the patient is diagnosed and the prescription is filled.
The Retail Healthcare Pivot
The acquisition of Aetna changed the purpose of the physical CVS retail store. The company is actively shrinking the amount of floor space dedicated to retail merchandise (like greeting cards and candy) and converted some stores into "HealthHUB" locations with expanded clinical services, a format it later scaled back. The goal is to manage the health of Aetna's insured members. If an Aetna member uses a CVS MinuteClinic for basic blood pressure management rather than going to an expensive hospital emergency room, the insurance division saves amounts of money, increasing the overall profitability of the conglomerate.
Primary Care Consolidation
To finalize the vertical integration strategy CVS is moving into primary care. In 2023, the company acquired Oak Street Health for $10.6 billion, a major network of primary care clinics focused specifically on Medicare Advantage patients. By controlling the primary care doctor, CVS controls the starting point of the patient's healthcare journey, dictating which specialists they see and which drugs they are prescribed. The integrated model has also drawn scrutiny from antitrust regulators and lawmakers, who argue that CVS's market power across insurance, pharmacy, and primary care allows it to squeeze out independent pharmacies and artificially inflate the cost of prescription drugs for the American consumer.
The 2024 Crisis and 2026 Recovery
Rising Medicare Advantage costs crushed Aetna's profits in 2024, and David Joyner replaced Karen Lynch as CEO in October. CVS still posted record FY2025 revenue of $402.1 billion, but a $5.7 billion goodwill impairment on its care delivery unit cut net income to $1.77 billion. In 2026, Aetna's medical benefit ratio improved to 87.4% in the second quarter, quarterly net income tripled to $3.0 billion, and CVS raised full-year guidance to at least $414 billion in revenue.
