UnitedHealth combines UnitedHealthcare with four Optum businesses, while CVS Health combines Aetna coverage, pharmacy-benefit and health services, and a large retail pharmacy operation.
The figures below use the quarter ended June 30, 2026, the latest period reported by both companies at the October 13, 2026 cutoff. Revenue shows scale; it does not by itself show which company earns more on each dollar, carries lower medical risk, or offers better shareholder returns.

Why Q2 2026 is the correct common period
The comparison is deliberately limited to the second quarter ended June 30, 2026. UnitedHealth had announced that its third-quarter release would arrive before market open on October 13, 2026, but that announcement placed the release after the October 13, 2026, 06:26:41 UTC information cutoff used here. The schedule notice is available from UnitedHealth. Using a later UnitedHealth quarter against CVS’s Q2 would create an uneven comparison.
#1 Best Overall
This timing distinction matters because health insurers can experience sharp quarter-to-quarter changes in medical claims, enrollment mix, pharmacy activity and reserve development. A common period reduces that distortion, although it cannot eliminate differences in accounting or business mix.
How UnitedHealth Group is built
UnitedHealthcare: the health-benefits operation
UnitedHealthcare is UnitedHealth Group’s health-benefits business. It collects premiums or other coverage payments, administers plans and pays or manages covered medical care. Its economics are therefore heavily influenced by enrollment, premium rates, government-program policy, provider costs and the timing of claims.
Optum Health: care and health services
Optum Health delivers care and related health services. It gives UnitedHealth a direct-services component alongside the insurance operation, rather than leaving the group dependent solely on premium revenue.
Optum Insight: data and technology
Optum Insight provides technology, analytics and information-related services. These activities are economically different from underwriting medical risk: contracts, software and data services can have different revenue timing, margins and capital needs than insurance coverage.
Optum Rx: pharmacy services
Optum Rx is the group’s pharmacy-services business. It connects UnitedHealth to prescription-benefit activity and creates another channel through which the group participates in medication spending and management.
UnitedHealth describes UnitedHealthcare and Optum as complementary businesses. That description is company framing, not proof that every internal service produces superior results. For financial analysis, the four reportable segments in the 2025 filing are the authoritative map; see the UnitedHealth Group 2025 Form 10-K.
Rank #2
How CVS Health is built
Health Care Benefits: Aetna coverage
CVS Health’s Health Care Benefits segment contains Aetna health insurance and related services. It is the part of CVS most directly exposed to premiums, enrollment, medical utilization and the difference between collected premiums and the cost of covered care.
The Tool Desk
Outbyte Driver Updater FREEScan for outdated or missing drivers - takes under a minuteDriver Scan →Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →Health Services: pharmacy-benefit and healthcare services
Health Services includes pharmacy benefit management and other healthcare services. A pharmacy-benefit manager may process prescriptions, negotiate or administer benefits and coordinate pharmacy spending; the segment also includes services beyond a traditional retail pharmacy. Because pharmacy transactions can involve large underlying drug amounts, the revenue line must be read with the segment’s accounting presentation and intersegment eliminations in mind.
Pharmacy & Consumer Wellness: stores and products
Pharmacy & Consumer Wellness covers retail and other pharmacy operations together with consumer health products. Its revenue mix includes transactions at physical locations and related consumer activity, making it more visibly retail-oriented than UnitedHealth’s reported structure.
Corporate/Other
Corporate/Other contains activities that are not assigned to the three operating segments. It should not be treated as a fourth customer-facing business equivalent to Aetna, Health Services or the retail operation.
CVS’s four-segment structure is defined in its audited 2025 Form 10-K. The filing is the source of record for segment definitions, annual results, cash flow, balance-sheet items and risk factors.
Segment map: what is and is not comparable
| Economic activity | UnitedHealth reporting home | CVS Health reporting home | Comparison caution |
|---|---|---|---|
| Health insurance and benefits | UnitedHealthcare | Health Care Benefits | These are the closest insurance comparisons, but enrollment mix, government exposure and product composition can differ. |
| Care delivery and clinical services | Primarily Optum Health | Health Services and some activities associated with Health Care Benefits | CVS does not present a segment named Optum Health, so a one-to-one match is unavailable. |
| Pharmacy-benefit services | Optum Rx | Health Services | Both participate in pharmacy-benefit activity, but reporting boundaries and revenue presentation differ. |
| Data, analytics and technology | Optum Insight | Included within CVS Health Services or other disclosed activities | CVS does not report a separately named equivalent segment in the cited structure. |
| Retail pharmacy and consumer products | No separately reported retail-pharmacy segment in the cited structure | Pharmacy & Consumer Wellness | CVS has a substantial consumer-facing retail component that changes its revenue mix. |
Q2 2026 financial comparison
Revenue scale
UnitedHealth reported $112.0 billion of Q2 2026 revenue, while CVS Health reported $106.096 billion. The arithmetic difference is approximately $5.904 billion, or about 5.6% of CVS Health’s reported quarterly revenue. That answers the narrow question “which reported more revenue?”: UnitedHealth did.
Rank #3
It does not answer which company has better revenue quality. UnitedHealth’s total combines health-benefit premiums with Optum activities. CVS’s total combines insurance, pharmacy-benefit and healthcare services, retail pharmacy and consumer products. A dollar of retail sales, a dollar of pharmacy-service revenue and a dollar of insurance premium do not carry the same costs or risks.
Operating earnings: keep GAAP and adjusted measures separate
UnitedHealth reported $8.0 billion in earnings from operations. CVS reported $4.703 billion of GAAP operating income and separately reported $5.157 billion of adjusted operating income. The CVS release’s two figures are different measures; an adjusted figure reflects exclusions or adjustments defined in the company’s reconciliation, while GAAP operating income follows generally accepted accounting principles.
A fair comparison therefore starts with reported operating measures on the same basis. Pairing CVS’s adjusted operating income with UnitedHealth’s reported earnings from operations and calling the result a definitive profitability ranking would mix definitions. If an analyst chooses adjusted figures, the same adjustment policy should be applied consistently to both companies, with every exclusion disclosed.

UnitedHealth’s reported net margin
UnitedHealth’s Q2 release states a 4.9% net margin. Net margin is calculated after operating costs, non-operating items, interest, taxes and other items affecting net income; it is not the same as an operating margin. CVS’s cited Q2 release supplies GAAP and adjusted operating measures and segment information, but the comparison above does not establish a matching CVS net-margin figure.
For that reason, the table’s operating figures should be used to understand the quarter, not to make a blanket statement that one company is permanently more profitable. Medical-cost trends, pharmacy economics, reserve development and one-time items can change the relationship in later periods.
What CVS’s medical benefit ratio says
CVS Health reported an 87.4% Health Care Benefits medical benefit ratio for Q2 2026, compared with 89.9% in Q2 2025. In plain language, this is an insurance medical-cost indicator for that segment: it tracks medical benefit costs relative to the applicable premium base. It is not CVS Health’s consolidated operating margin and should not be compared directly with UnitedHealth’s net margin or total-company earnings from operations.
CVS attributed the year-over-year reduction primarily to improved underlying performance in its Government business and the absence of the prior-year premium deficiency reserve. Those explanations describe the quarter’s movement; they do not establish that the lower ratio is a permanent trend. A reader evaluating future periods should check whether the same drivers persist, whether utilization changes, and whether new reserve adjustments appear.

Different kinds of sales are combined
Insurance premiums, pharmacy-benefit services, care-delivery contracts, data services and retail purchases all appear within these groups’ consolidated results. They can have different gross-versus-net presentation, timing and cost structures. A higher consolidated revenue number can therefore reflect a different mix rather than superior economics.
Internal transactions are eliminated
Each company has businesses that transact with other businesses in the same group. Consolidated statements eliminate intersegment revenue so internal activity is not counted as external sales. Segment totals may consequently add to more than the consolidated figure, or require reconciliation, even though every segment is reported correctly.
Pharmacy transaction volume is not the same as profit
Pharmacy claims, prescription payments, rebates and retail copayments can involve large dollar flows. The amount processed or sold is not equivalent to the fee or margin retained by the company. Always inspect the segment’s reported revenue, operating income, cash flow and reconciliation rather than interpreting transaction volume as profit.

CVS reported the following company-wide scale indicators at December 31, 2025:
| CVS Health indicator | Reported amount | What it measures |
|---|---|---|
| Retail locations | Approximately 9,000 | Physical retail sites, not covered lives or unique customers. |
| Walk-in and primary-care clinics | More than 1,000 | Clinic locations, not the number of visits or enrolled members. |
| Pharmacy-benefit manager plan members | About 87 million | PBM plan membership, a services denominator rather than an insurance-covered-life count. |
| People served through insurance products and related services | Estimated more than 37 million | An estimated insurance-related population, not directly comparable with PBM plan members or retail shoppers. |
These are company-reported indicators from CVS’s 2025 Form 10-K. The cited materials do not provide a directly equivalent UnitedHealth table of retail locations, PBM plan members, clinics and insurance consumers. “Covered lives,” “PBM plan members,” “locations,” “prescriptions” and “consumers served” should therefore remain separate measures. A larger number in one category does not prove broader reach in another.
How to make an annual comparison
For a full-year analysis, use both companies’ audited fiscal-year filings for the year ended December 31, 2025: the UnitedHealth Group Form 10-K and the CVS Health Form 10-K. Those filings provide the authoritative annual revenue, operating results, cash-flow statements, balance sheets, segment disclosures and risk factors.
Keep the periods aligned. Do not compare UnitedHealth’s fiscal-year 2025 with a CVS quarter, a trailing-twelve-month figure or a management forecast. Record whether each number is GAAP, adjusted, reported for a segment or consolidated, and whether it includes an intersegment-elimination adjustment.
An annual worksheet should include, at minimum:
- Consolidated revenue and the principal external revenue sources.
- GAAP operating income and net income, with adjusted measures in a separate column.
- Medical benefit or care ratios for comparable insurance segments, with their exact definitions.
- Cash from operations, capital spending and major balance-sheet changes.
- Enrollment, PBM membership, clinic and retail-location measures, each labeled by denominator.
- Management guidance shown separately from results already reported.
Management commentary versus demonstrated results
UnitedHealth chief executive officer Stephen Hemsley described the Q2 outlook this way: “Our results and outlook reflect the continuing progress in our work to simplify how we operate, improve both affordability and the healthcare experience for patients and care providers, and apply modern technology to create real improvement for people.” This is management’s framing of its priorities and outlook, not independent evidence that those outcomes have been achieved. The reported revenue, operating earnings, margin and segment metrics remain the evidence to analyze.
A practical framework for deciding what the comparison means
If your question is “Which company is bigger?”
Use consolidated revenue for the same quarter or fiscal year. On the aligned Q2 2026 measure, UnitedHealth reported the higher total. Do not substitute retail locations, PBM members or estimated people served for revenue.
If your question is “Which business is more diversified?”
Map the segments first. UnitedHealth’s structure emphasizes an insurance business alongside Optum care, data, technology and pharmacy services. CVS combines insurance with Health Services and a large retail-pharmacy and consumer-health operation. Diversification can reduce dependence on one revenue source, but it also exposes each group to different execution and cost pressures; the segment disclosures are needed to judge the trade-off.
If your question is “Which is more profitable?”
Start with GAAP operating income and net income for the same period, then show adjusted figures in a separate analysis. Do not compare CVS’s adjusted operating income with a GAAP figure from UnitedHealth as though they were identical.
If your question is “Are insurance costs improving?”
Read the relevant medical-cost ratio within the insurance segment and study its year-over-year drivers. CVS’s Q2 MBR improvement was linked to Government-business performance and the absence of a prior-year reserve; one quarter does not establish a durable trend. A comparable UnitedHealth ratio would need to come from UnitedHealth’s own segment disclosure and definition.
If your question is “Who reaches more people?”
Define the population first: insured members, PBM plan members, clinic users, retail shoppers or people served through related services. The available CVS figures use different denominators, and the cited materials do not establish matching UnitedHealth counts. Any conclusion that ignores those definitions is likely to overstate precision.
Bottom line
UnitedHealth Group led CVS Health in Q2 2026 consolidated revenue, but the gap was a scale observation for one aligned quarter, not a verdict on quality, valuation or future performance. UnitedHealth is organized around UnitedHealthcare and four Optum segments; CVS combines Aetna coverage, Health Services and Pharmacy & Consumer Wellness. The most reliable comparison keeps periods aligned, separates GAAP from adjusted earnings, treats medical benefit ratios as segment measures, and labels every reach statistic by its denominator.
