CVS Health Corp.: CVS Health is a Woonsocket, Rhode Island-based health care company and one of the largest U.S. companies by revenue. Most consumers know it as the CVS Pharmacy on the corner, but the retail store is only one of three businesses. CVS also owns Aetna, one of the largest U.S. health insurers, and CVS Caremark, one of the three largest pharmacy benefit managers. Together with Oak Street Health clinics, Signify Health in-home visits, and MinuteClinic, the company connects with roughly 185 million consumers.

UnitedHealth Group Incorporated: UnitedHealth is best understood as a healthcare operating system: insurance premiums and claims create scale, Optum manages pharmacy and care services, and data flows help price risk, coordinate care, and manage cost.

CVS Health Corp. and UnitedHealth Group Incorporated pursue distinct approaches to generating revenue, and understanding how each company operates is the foundation of any fair comparison between CVS Health Corp. and UnitedHealth Group Incorporated.

CVS Health Corp. business model: 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.

UnitedHealth Group Incorporated business model: UnitedHealth makes money in two connected ways. UnitedHealthcare collects premiums from employers, individuals and government programs (Medicare Advantage and Medicaid) and earns fees for administering self-funded employer plans; profit depends on keeping medical costs below premiums. Optum sells services: Optum Rx runs pharmacy benefit management and specialty pharmacy, Optum Health delivers primary, specialty and home care (often under value-based contracts that pay a fixed amount per patient), and Optum Insight sells data, analytics, claims and revenue-cycle technology. Optum serves UnitedHealthcare and outside payers, so some dollars UnitedHealthcare pays out return as Optum revenue. Premiums from CMS programs made up 44% of 2025 consolidated revenue.

The durability of a company's moat often decides long-term winners. Here is how the competitive advantages of CVS Health Corp. stack up against those of UnitedHealth Group Incorporated.

CVS Health Corp. competitive advantage: CVS's edge is integration at national scale. About 85% of Americans live within 10 miles of a CVS Pharmacy, Caremark manages roughly 1.9 billion prescriptions a year, and Aetna covers about 26 million medical members. Owning the insurer, the PBM, and the pharmacy lets CVS capture purchasing economics (including private-label biosimilars through Cordavis), steer care to lower-cost settings such as MinuteClinic and Oak Street Health, and combine claims and pharmacy data that standalone rivals cannot match. The same integration is also what draws regulators' attention.

UnitedHealth Group Incorporated competitive advantage: UnitedHealth's advantage is vertical integration. It combines the largest U.S. health insurer with Optum's pharmacy, care delivery, data, analytics, and services assets, giving it scale in claims, benefits, networks, prescriptions, and care management.

Future prospects matter as much as current results. The growth strategies below explain how CVS Health Corp. and UnitedHealth Group Incorporated each plan to expand from here.

CVS Health Corp. growth 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.

UnitedHealth Group Incorporated growth strategy: UnitedHealth is focused on pricing and benefit design, medical cost management, Medicare Advantage discipline, Medicaid and employer offerings, Optum Rx scale, Optum Health care delivery, technology, data analytics, and value-based care capabilities.

A closer look at the financial trajectory of CVS Health Corp. and UnitedHealth Group Incorporated rounds out the comparison.

CVS Health Corp.: CVS Health's revenue grew from $292.1B in 2021 to $402.1B in 2025, an 8.3% compound rate, but profitability moved the other way: adjusted EPS fell from $8.40 to $6.75 as Aetna's Medicare Advantage costs surged in 2024. FY2025 GAAP diluted EPS was just $1.39 because of a $5.7B goodwill impairment in the Health Care Delivery unit and $1.2B in legacy litigation charges, while cash flow from operations was $10.6B. 2026 marks a turnaround: first-half revenue reached $206.5B, Aetna's medical benefit ratio improved to 87.4% in Q2 from 89.9% a year earlier, and full-year guidance was raised to at least $414B in revenue, $7.90-$8.10 adjusted EPS, and at least $11.5B in operating cash flow.

UnitedHealth Group Incorporated: UnitedHealth Group grew 2025 revenue 12% to $447.6 billion, yet earnings from operations fell from $32.3 billion in 2024 to $19.0 billion as Medicare Advantage and Optum Health medical costs ran well above pricing. Net margin was 2.7% and operating cash flow was $19.7 billion. 2026 is a repair year: management guided to more than $439 billion in revenue, a slight decline from planned right-sizing of membership, and after a Q2 with $112.0 billion revenue, $8.0 billion operating earnings and an 86.7% adjusted medical care ratio, raised adjusted EPS guidance to $19.50 to $20.00.
