UnitedHealth Group reported second-quarter adjusted EPS of $6.38 against roughly $4.85 expected, on revenue of $112.03 billion, and raised full-year adjusted EPS guidance to $19.50 to $20.00 from a prior outlook above $18.25. The stock rose about 7% premarket.
The number driving all of it was the medical benefit ratio, the share of premium dollars paid out as medical care. It fell to 86.7% from 89.4% a year earlier, roughly 270 basis points, against analyst expectations closer to 88.5%. On a base of $112 billion in quarterly revenue, that spread is enormous.
Now the other set of numbers from the same quarter. UnitedHealthcare served 48.5 million people, down 525,000 sequentially. Medicare Advantage membership has contracted by 965,000 since year-end 2025. Community and State, its Medicaid business, fell by 380,000 in the quarter. Optum Health revenues declined 5% year over year on roughly 700,000 fewer value-based care patients. For the full year, the company forecasts losing about 500,000 ACA exchange members and 1.1 million Medicare Advantage members.
Profits up sharply, membership down sharply. Those are not independent developments.
The CFO said the quiet part plainly
The most useful thing in the entire earnings cycle was CFO Wayne DeVeydt's characterization of what happened, and it is unusually direct for a company reporting a 30% beat. Medical costs, he said, remained elevated over historical levels, and: these results are not a reflection of trend bending or coming under control, but rather our efforts to start pushing down what is already an elevated number.
That is a chief financial officer stating that the improvement did not come from health care getting cheaper. It came from the company managing its exposure to health care that remains expensive.
The mechanics are visible in the disclosures. The margin improvement came from changes to health insurance benefits, product pricing strategy, and the exit of membership in Medicare Advantage and ACA exchange plans that were priced below cost. Benefit redesign, repricing, and exiting unprofitable business.
And the revenue effect is the tell: premium increases have been large enough to keep overall revenue flat despite the drop in members. Fewer members, each paying more, selected toward the profitable end. That is a coherent and entirely legal business strategy. It is also, precisely, margin improvement through selection and pricing rather than through cost control.
Where those members went
DeVeydt attributed membership declines largely to affordability pressures driven by higher healthcare costs.
That sentence deserves to be read alongside everything else known about 2026. Enhanced ACA subsidies expired at the end of 2025 and out-of-pocket premiums roughly doubled for subsidized enrollees. Marketplace enrollment fell by millions. Surgical device makers are reporting that patients are deferring elective procedures.
So when the largest US insurer forecasts losing 500,000 exchange members and 1.1 million Medicare Advantage members to affordability pressure, it is describing, from the inside, the same phenomenon those other data points describe from outside. The difference is that for the company, this shows up in the margin line as an improvement.
That is not a moral accusation. An insurer cannot force people to buy coverage they cannot afford, and exiting plans priced below cost is what a responsible operator does rather than subsidize losses indefinitely. But it is worth being clear-eyed about the structure: when the people leaving are disproportionately those who cost more relative to what they pay, their departure improves the remaining pool. The affordability crisis and the margin recovery are the same event viewed from two sides of the ledger.
Three details that matter more than the headline
Medicaid is losing money and Medicare is not. Medicaid margins are expected to run between negative 1% and negative 1.7% for the full year, while Medicare margins are projected to finish above 3%. That gap explains a lot of behavior across the industry. Medicaid managed care is a business insurers participate in at or below breakeven, dependent on state rate-setting, while Medicare Advantage is where the margin lives. The company also exited the Louisiana health plan, contributing to the Community and State decline.
The company is naming provider billing as a cost driver. Commercial cost trend is running modestly above 11%, driven by the Independent Dispute Resolution process and more intensive provider billing practices. That is the payer side of the documented arms race in which providers deploy AI to capture more billable complexity and payers respond with automated review and downcoding. UnitedHealth is now quantifying it in its cost trend, which is a notable acknowledgment that the escalation is measurably expensive.
Star ratings are deteriorating industry-wide. Management noted the Stars program has continued to get more challenging, with 2026 industry scores at the lowest level in about a decade. Since star ratings drive quality bonus payments, that is a forward revenue headwind for the whole sector, and it is one reason several insurers have been litigating against CMS over ratings calculations.
The concessions worth noticing
Alongside the results, the company announced it will rebate 2026 profits on individual ACA coverage to roughly 1 million members, cut 30% of prior approvals, and target 100% pass-through of manufacturer drug rebates by January 1, 2028, plus a $1 billion commitment to the United Health Foundation.
These are meaningful, particularly the prior authorization reduction, which addresses a genuine and well-documented source of patient harm. They are also arriving during active DOJ civil and criminal investigations into Medicare Advantage coding and risk-adjustment practices and sustained congressional scrutiny. Both things can be true: the commitments have real value for patients, and they are being made by a company with strong reasons to demonstrate good faith. Whether the 30% prior-approval cut covers the categories where denials do the most damage, drugs and post-acute care, is the detail to watch.
What the quarter actually demonstrates
Strip it down and this earnings report is a clean illustration of how health insurance profitability works when costs are rising.
An insurer facing elevated medical trend has three levers: cut costs, raise prices, or change who it covers. Cost trend did not improve, and the CFO said so. So the improvement came from the other two. Prices rose enough to hold revenue flat with 525,000 fewer members, and the company exited business priced below cost.
The result is a company earning more from covering fewer people, in a year when affordability is pushing people out of coverage. The system is not getting cheaper. The largest participant in it is getting better at not paying for the parts that cost the most, and its shareholders are being rewarded for it while 1.6 million people are expected to leave its rolls this year.
