CompanyYearPricePurpose
Caremark Rx2007$26.5BCVS merged with Caremark Rx, one of the United States' largest pharmacy benefit managers, to gain control over a critical link in the pharmaceutical distribution chain. The deal was defensive and offensive simultaneously defensive in that PBM power over retail pharmacy reimbursement rates was threatening CVS's core business economics, and offensive in that owning a major PBM would give CVS access to prescription volume and employer relationships that retail pharmacy alone could not generate. The transaction created CVS Caremark Corporation, one of the largest healthcare companies in the U.S. By revenue at the time.
MinuteClinic2006$170.0MCVS acquired MinuteClinic, a walk-in clinic operator staffed by nurse practitioners providing acute and preventive care services, to establish a clinical care capability within its retail pharmacy footprint. The acquisition was prescient it gave CVS the infrastructure to offer healthcare services beyond prescription dispensing, positioning the company as a primary care access point for patients seeking convenient, affordable alternatives to traditional physician office visits. MinuteClinic's model aligned naturally with CVS's retail pharmacy traffic patterns and high-volume, appointment-free service model.
Aetna Inc.2018$69.0BCVS's acquisition of Aetna, America's third-largest health insurer at the time, was the defining strategic move of the company's modern era and the largest healthcare acquisition in U.S. History. The deal was driven by the belief that owning an insurance company would give CVS both a captive customer base for its pharmacy and PBM services and the ability to align financial and clinical incentives across the full healthcare journey of millions of members. CVS's leadership argued that Aetna's insurance economics and CVS's pharmacy and clinical capabilities were mutually reinforcing reducing medical costs through better medication management, care coordination, and preventive services.
Oak Street Health2023$10.6BCVS acquired Oak Street Health to establish a value-based primary care capability specifically designed for Medicare patients, adding a critical clinical layer to its integrated healthcare model. Oak Street's differentiated approach serving Medicare patients in underserved urban communities through a capitated, outcomes-focused primary care model complemented Aetna's Medicare Advantage insurance operations and Caremark's pharmacy benefit management by providing the primary care coordination function that CVS had lacked. The acquisition was intended to demonstrate that CVS's integrated model could genuinely reduce total medical costs by keeping high-risk patients healthier through proactive primary care.
Peoples Drug Stores1990UndisclosedCVS acquired Peoples Drug, an approximately 490-store chain concentrated in the Mid-Atlantic region, to extend its pharmacy retail footprint beyond New England into the Washington D.C. Metropolitan area and surrounding markets. The acquisition represented CVS's first major geographic expansion outside its northeastern stronghold and established the acquisition-led growth playbook that would define CVS's retail pharmacy strategy through the 1990s and into the 2000s.

Oak Street Health

2023

$10.6B

Why

CVS acquired Oak Street Health to establish a value-based primary care capability specifically designed for Medicare patients, adding a critical clinical layer to its integrated healthcare model. Oak Street's differentiated approach serving Medicare patients in underserved urban communities through a capitated, outcomes-focused primary care model complemented Aetna's Medicare Advantage insurance operations and Caremark's pharmacy benefit management by providing the primary care coordination function that CVS had lacked. The acquisition was intended to demonstrate that CVS's integrated model could genuinely reduce total medical costs by keeping high-risk patients healthier through proactive primary care.

Impact

Oak Street gave CVS a value-based primary care model for Medicare patients, paid largely through capitated arrangements, alongside its existing MinuteClinic acute care.

Outcome

Center growth and profitability lagged plan, and CVS recorded a $5.7B goodwill impairment on its Health Care Delivery reporting unit in 2025. CVS reported modest improvement in health care delivery results in 2026, but the deal's payoff remains unproven.

Signify Health

2023

$8.0B

Why

CVS bought Signify Health, a provider of in-home health evaluations and value-based care enablement, to extend its reach into patients' homes and support risk-based contracts.

Impact

Signify added a large network of clinicians performing in-home assessments, mainly for Medicare Advantage plans, inside the Health Services segment.

Outcome

Signify remains part of CVS's care delivery business, which was hit by the 2025 Health Care Delivery goodwill impairment.

Aetna Inc.

2018

$69.0B

Why

CVS's acquisition of Aetna, America's third-largest health insurer at the time, was the defining strategic move of the company's modern era and the largest healthcare acquisition in U.S. History. The deal was driven by the belief that owning an insurance company would give CVS both a captive customer base for its pharmacy and PBM services and the ability to align financial and clinical incentives across the full healthcare journey of millions of members. CVS's leadership argued that Aetna's insurance economics and CVS's pharmacy and clinical capabilities were mutually reinforcing reducing medical costs through better medication management, care coordination, and preventive services.

Impact

The acquisition immediately vaulted CVS to the top tier of American healthcare companies by revenue, adding approximately $60 billion in annual revenues and coverage of more than 22 million medical members. It gave CVS access to Aetna's provider network, brand recognition, and enrollment infrastructure across commercial, Medicare, and Medicaid markets. The deal also introduced CVS to the operating dynamics and regulatory complexity of health insurance underwriting, a business with different risk management requirements than retail pharmacy or PBM administration.

Outcome

Aetna's Medicare Advantage losses drove the 2024 earnings collapse and CEO change. Repricing restored segment adjusted operating income to about $2.9B in 2025, and Q2 2026 segment adjusted operating income rose 85.5% to $2.4B.

Caremark Rx

2007

$26.5B

Why

CVS merged with Caremark Rx, one of the United States' largest pharmacy benefit managers, to gain control over a critical link in the pharmaceutical distribution chain. The deal was defensive and offensive simultaneously defensive in that PBM power over retail pharmacy reimbursement rates was threatening CVS's core business economics, and offensive in that owning a major PBM would give CVS access to prescription volume and employer relationships that retail pharmacy alone could not generate. The transaction created CVS Caremark Corporation, one of the largest healthcare companies in the U.S. By revenue at the time.

Impact

The merger transformed CVS from a retail pharmacy chain into an integrated pharmacy services company capable of competing on multiple dimensions of the pharmaceutical supply chain. Caremark's employer relationships gave CVS access to benefit design influence that enhanced its competitive position relative to pure retail pharmacy rivals. However, the combination created significant conflict-of-interest perceptions among Caremark's employer clients, who worried that a PBM owned by a retail pharmacy chain would direct members toward CVS stores rather than making objective formulary decisions.

Outcome

CVS Caremark became the dominant integrated pharmacy services company in the U.S. And Caremark has remained the largest revenue contributor to CVS Health's enterprise. Client retention challenges in the early post-merger years were addressed through governance commitments and pricing transparency programs, and Caremark's competitive position stabilized over time as the integrated model demonstrated value in specialty pharmacy and clinical management.

MinuteClinic

2006

$170M

Why

CVS acquired MinuteClinic, a walk-in clinic operator staffed by nurse practitioners providing acute and preventive care services, to establish a clinical care capability within its retail pharmacy footprint. The acquisition was prescient it gave CVS the infrastructure to offer healthcare services beyond prescription dispensing, positioning the company as a primary care access point for patients seeking convenient, affordable alternatives to traditional physician office visits. MinuteClinic's model aligned naturally with CVS's retail pharmacy traffic patterns and high-volume, appointment-free service model.

Impact

MinuteClinic grew from a small regional operator into a network of approximately 1,100 locations embedded in CVS Pharmacy stores across more than 35 states, becoming one of the largest walk-in clinic networks in the United States. The clinics provide an estimated millions of patient encounters annually, generating clinical revenue while deepening patient relationships with the CVS brand. MinuteClinic also serves as a prescription generation channel, as a meaningful share of patients who receive care at MinuteClinic fill resulting prescriptions at the adjacent CVS Pharmacy.

Outcome

MinuteClinic demonstrated the viability of retail-based clinical care at significant scale, validating CVS's broader thesis about transforming pharmacies into healthcare destinations. The network has been instrumental in demonstrating CVS's clinical capabilities to potential Aetna and Caremark clients who benefit from the company's ability to manage patient care across clinical and pharmacy touch points. MinuteClinic was eventually complemented by the larger HealthHUB format and Oak Street Health's primary care model.

Peoples Drug Stores

1990

Why

CVS acquired Peoples Drug, an approximately 490-store chain concentrated in the Mid-Atlantic region, to extend its pharmacy retail footprint beyond New England into the Washington D.C. Metropolitan area and surrounding markets. The acquisition represented CVS's first major geographic expansion outside its northeastern stronghold and established the acquisition-led growth playbook that would define CVS's retail pharmacy strategy through the 1990s and into the 2000s.

Impact

The Peoples Drug acquisition roughly doubled CVS's store count and gave the company a meaningful presence in several of the nation's largest metropolitan markets. It also provided operational scale in purchasing, distribution, and store management that improved CVS's cost position versus smaller regional competitors. The acquisition demonstrated that CVS could integrate a large, geographically distinct retail chain a capability that would prove essential in the far larger acquisitions that followed.

Outcome

Peoples Drug's stores were converted to the CVS format, establishing CVS as a national rather than regional pharmacy chain. The acquisition proved a template for the subsequent Revco acquisition in 1997 and set the organizational capability for large-scale integration that CVS would need repeatedly in its growth-through-acquisition strategy over the following three decades.

CVS Health Corp.'s Growth & Acquisition Strategy

Under David Joyner, CVS has shifted from deal-making to execution: repricing and shrinking unprofitable Aetna business (including exiting the individual ACA exchange market in 2026), moving CVS Pharmacy to cost-based reimbursement contracts, buying prescription files from 626 former Rite Aid pharmacies in 2025, exiting the Omnicare long-term care pharmacy business, and expanding GLP-1 access programs across Caremark, CVS Pharmacy, and MinuteClinic. It is also deploying AI tools such as Aetna's Claims Assist Manager and agentic AI for call centers to cut administrative cost.

How CVS Health Corp. Makes Money

CVS Health earns money in three connected segments. Health Services (FY2025 revenue $190.4B) is mainly CVS Caremark, which administers pharmacy benefits for employers, health plans, and government clients, runs mail-order and specialty pharmacies, and includes Oak Street Health primary care and Signify Health in-home evaluations. Health Care Benefits ($143.4B) is Aetna, which collects premiums and fees for commercial, Medicare Advantage, Medicare Part D, and Medicaid coverage. Pharmacy & Consumer Wellness ($139.4B) is CVS Pharmacy, which dispenses about 28.5% of all U.S. retail prescriptions and sells front-store health and beauty products. Because one segment often sells to another, about $71.6B of intercompany revenue is eliminated to reach the reported $402.1B total.
