Written on October 22, 2026, after its third-quarter results. Figures are from the company’s filings and releases unless noted. Not investment advice. The author holds no UNH shares directly.

01 · The business

Insurer, doctor and pharmacy manager.

UnitedHealthcare insures tens of millions of people through employers, Medicare Advantage and Medicaid. Optum Health employs or contracts with tens of thousands of doctors; Optum Insight sells data, software and claims services to hospitals and insurers; Optum Rx manages drug benefits.

The combination is the point and the controversy: UnitedHealth earns money on both sides of many transactions, which lowers costs when it works and draws scrutiny from regulators.

02 · Latest results

Profit up 52%, guidance raised a third time.

88.4%Medical care ratio, from 89.9%
$6.6BEarnings from operations
≥$20.502026 adjusted EPS guidance
13–16%Long-term EPS growth target

Third-quarter revenue was flat at $112.7 billion as UnitedHealth shed unprofitable members, but earnings from operations rose 52% to $6.6 billion and adjusted earnings to $4.69 a share, well above forecasts. The medical care ratio, the share of premiums paid out in care, fell to 88.4% from 89.9%, helped by $610 million of favorable reserve releases. Optum Health’s profit rose to $735 million from $41 million.

Guidance was raised for the third time, to at least $20.50 a share. Medicare Advantage margins should end the year near the top of the 2–4% target and Medicaid margins return to target by the end of 2028; commercial medical costs remain above the 11% trend the company assumed.

03 · The numbers

Margins halved, now recovering.

Free cash flow$19.9B$23.4B$25.7B$20.7B$16.1B$23.6B

The operating margin fell from more than 8% to about 4% in 2025 as medical costs, especially in Medicare Advantage, ran far ahead of what UnitedHealth had priced, and it changed chief executive and faced a federal investigation of its Medicare billing. The last column is to June 2026, before the third-quarter recovery. The quarterly view shows each quarter.

04 · Balance sheet and ownership

Debt to capital above target.

At September 30 UnitedHealth had $74.3 billion of debt and $28.5 billion of cash and short-term investments, much of it held by regulated insurance subsidiaries. Its debt-to-capital ratio was 41.7%, above its 40% target. It bought back $5.0 billion of shares and paid $6.2 billion of dividends in the first nine months.

Every figure in this valuation comes from one model script, rerun and checked against this page each time the site is built. The XLSX model rebuilds it in live formulas: change any blue input and every year’s cash flow, the bridge to the value, the scenarios and the sensitivity table recalculate.

06 · What the price assumes

At $425, a partial recovery.

To justify the price, you needAgainst
Revenue growth of about 2% a year for two years, then the same fade4% and 7%
Or a long-run operating margin of about 5.9%7%

The price assumes margins recover only a little from here. The shares rose about 12% after the results, to near their 52-week high; analysts average about $481.

07 · Risks

What could go wrong, and what could go right.

RiskWhy it matters
Medical costsCommercial cost trend is still above plan; specialty drugs and hospital use keep rising.
Medicare AdvantageGovernment rates, star ratings and coding rules set most of the profit.
InvestigationsFederal scrutiny of Medicare billing and of Optum’s ties to the insurer.
Pharmacy benefitsRebate pass-through by 2028 and drug-pricing reform reshape Optum Rx.
Reserve releasesPart of this year’s improvement came from one-off releases.

Upside: margins back to pre-2025 levels, Optum Health recovering further, and buybacks resuming at scale once debt is back at target.

08 · Rating

Buy. A recovery the price only partly believes.

UnitedHealth’s margins have started to recover after the 2025 collapse, and guidance has been raised three times. The price assumes an operating margin of about 6% for good, against more than 8% before 2025.

What would change the value: The 2027 outlook, expected around the turn of the year, Medicare Advantage rates for 2028 and the outcome of federal investigations are the next inputs.

Ranges, not three cases. The expected value is the average of 4,000 runs of this report’s own model, with every input drawn from a range: the base case is the middle, and the bear and bull cases are the 10th and 90th percentiles. Business inputs move together; the discount rate moves on its own. The 25/50/25 weighting in the valuation section gives $538. How the ranges work

Two different questions. The rating is relative: it asks whether the stock is cheaper or dearer than the S&P 500 on the same assumptions. The absolute view asks whether it is worth its price at all: on its own the stock trades 22% below our estimated value.

On the same assumptions every report uses (a 5.15% Treasury yield and a 4.5% equity premium), the S&P 500 itself is worth about 68% of its price. The rating compares each stock with that: Buy if it is at least 15% cheaper than the market on this basis, Sell if at least 15% dearer, Hold in between. It is the same rule for every company, whoever owns it. The rating is the same whether the index is assumed to grow 6% or 10% a year. How ratings work

Against the Street: Analysts average about $481, closer to this model’s base case of $516; both assume margins keep recovering.

Final view

A recovery the price only partly believes.

Margins are coming back; the price assumes they stop short.
