UnitedHealth Group (NYSE: UNH) continued its strong 2026 performance on Thursday by delivering an outstanding second-quarter earnings report, with lower medical costs allowing profitability to soar. UnitedHealth Group raised its full-year guidance, and shares were up more than 8% in morning trading.
UnitedHealth Group stock is now up 37% in 2026, but it still has a potential long runway. The nation's largest health insurer is still more than 25% off all-time highs set in 2024 and seems to be building momentum to return to those lofty levels.

UnitedHealth Group's earnings
Revenue for the second quarter was solid, but unspectacular, coming in at $112 billion versus $111.6 billion a year ago. But earnings from operations were much higher, at $8 billion versus $5.2 billion in Q2 2025. And earnings per share were $6.04, up from $3.74 a year ago.
In addition, the company's medical care ratio -- the percentage of premium revenue paid in medical claims -- was 86.7%, compared to 89.4% a year ago. Management attributed the improvements to pricing discipline, member mix, and medical cost management initiatives.
"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," CEO Stephen Hemsley said.
UnitedHealth Group increased its full-year guidance to $25.45 billion in operating earnings, versus previous expectations of $24 billion. The company now expects adjusted earnings per share to be in a range of $19.50 to $20, versus previous guidance of $17.75 per share. It expects the full-year medical care ratio to be 88.1%, down from a previous expectation of 88.8%.
Improvements at Optum
Optum, which is UnitedHealth Group's healthcare services and technology business, also showed improved performance for the quarter. Revenue dropped from $67.2 billion a year ago to $65.7 billion in the most recent quarter as Optum served 700,000 fewer patients. However, earnings from operations were $4 billion, up from $3.1 billion a year ago.
Management attributed the improvement to operational improvements and medical cost management. And Optum is also rolling out a series of AI-enhanced products that should improve the company's revenue in the future, including autonomous coding and digital prior authorization tools.
"We are committed to making the health system work better for all stakeholders by simplifying processes, by being clearer, more consistent, and faster in the experience we offer, and by redesigning and modernizing that experience altogether," Hemsley said. "AI technology is helping us move faster."
Is UnitedHealth Group stock a buy?
UnitedHealth Group is a much different company than it was a year ago -- you may recall that the insurer missed analysts' estimates in the first quarter of 2025, triggering a massive sell-off and forcing management to undertake a host of projects to improve margins, including redesigning benefits, repricing plans, and making operational changes.
That work isn't over, but UnitedHealth Group is well on its way. And now that the federal government has announced better-than-expected payment rates for Medicare Advantage plans in 2027, increasing payments by 2.48%, UnitedHealth Group will be better positioned to maintain its margins and keep its medical care ratio at a reasonable level.
On top of that, UnitedHealth Group stock pays a solid 2% dividend yield, which is better than the 1.6% average yield for healthcare stocks.
Can the stock return to its 2024 high and top $600? That's a long road to go, but UnitedHealth Group is in a much better position today than it was a year ago, and I think it's a strong buy moving on the strength of its earnings report and guidance increase.

Four leading AI models discuss this article
"UNH's improved medical-cost ratio and guidance raise are real but insufficient to declare it a 'strong buy' while legacy risks around regulation, cyber exposure, and Optum membership erosion remain under-discussed."
UNH's Q2 results show genuine operational progress: medical care ratio improved 270bp to 86.7%, operating earnings jumped 54% to $8B, and full-year EPS guidance was raised $1.75–$2.25 to $19.50–$20.00. Optum's margin expansion despite lower revenue is encouraging, and the 2.48% Medicare Advantage rate increase for 2027 removes a prior overhang. At 37% YTD gains yet still 25% below 2024 highs and sporting a 2% dividend yield, the stock looks reasonably valued on 11–12x forward earnings against mid-teens EPS growth. However, the article glosses over persistent regulatory scrutiny, cyber-risk from the 2024 Change Healthcare breach, and Optum's patient loss of 700k which may signal competitive pressure or network narrowing.
A single quarter of margin recovery does not prove the redesign and repricing initiatives are sustainable; medical-cost trends can re-accelerate, Medicare rates can be clawed back in future years, and any renewed political push for price controls or public option could erase the current tailwinds.
"UNH's margin expansion is currently driven by defensive patient shedding and repricing, which creates a long-term regulatory and growth risk that the current price rally ignores."
UNH is executing a textbook margin recovery, but investors should be wary of the sustainability of this 'medical cost management.' The drop in the medical care ratio (MCR) to 86.7% is impressive, yet it stems from shedding 700,000 patients at Optum and aggressive plan repricing. While the 2027 Medicare Advantage rate hike of 2.48% provides a tailwind, UNH faces significant regulatory and political risk as the DOJ antitrust investigation into the Optum-UnitedHealthcare integration looms. With the stock up 37% YTD, much of the recovery is priced in; the path to $600 requires not just operational efficiency, but a clean bill of health on the legal front.
The MCR improvement may be masking a 'coverage cliff' where aggressive cost-cutting leads to higher future utilization, and the DOJ's scrutiny of the vertical integration model could force a structural breakup of Optum and the insurance arm.
"UNH's earnings beat is real, but Optum's revenue decline signals member flight risk, and the Medicare rate tailwind masks underlying pricing pressure that may not sustain a 25% move back to 2024 highs."
UNH's Q2 beat looks real on the surface—MCR compression from 89.4% to 86.7% YoY is substantial, and the $1.25B operating earnings beat ($8B vs. $5.2B) isn't noise. But the article buries the real story: Optum revenue fell 2.2% while serving 700k fewer patients. That's not operational excellence; that's member shedding. The 2027 Medicare Advantage rate increase of 2.48% is a tailwind, but it's also a ceiling—if UNH needed government help to stabilize margins, the pricing power narrative is weaker than the article suggests. The 37% YoY gain already prices in a meaningful recovery. Valuation matters here, but the article omits it entirely.
If UNH's margin recovery is durable and the Optum patient loss was deliberate (shedding unprofitable members), then the company has genuinely fixed its 2025 Q1 disaster—and the stock could re-rate toward 2024 highs on normalized multiples, not just earnings growth.
"UnitedHealth's run rate depends on durable margin expansion from pricing discipline and AI-driven productivity, plus continued MA rate support; any deterioration in these drivers could undermine upside."
UNH delivered a credible beat with Q2 revenue of $112B and EPS of $6.04, lifting 2026 guidance to $19.50–$20 and nudging the medical care ratio to 88.1%. Optum earnings rose even as revenue declined, aided by cost controls and AI-enabled tools like autonomous coding and digital prior authorization. The positives hinge on durable margin expansion and favorable MA payments in 2027. However, the bull case assumes sustained pricing power and patient volumes, plus ROI from AI that may take time to materialize. With a 37% YTD rise, valuation risk exists if policy or utilization trends disappoint.
The stronger case against is that the margin lift could be a near-term mix effect; AI-driven savings may prove slow to materialize, and Medicare Advantage tailwinds could be reversed or capped, threatening the earnings trajectory.
"Optum patient attrition may signal adverse selection bleeding into UNH's insurance MCR trajectory."
Claude correctly flags member shedding, but nobody has connected the 700k Optum loss directly to UNH's insurance book. If those were dual-eligible or MA lives migrating to competitors, it risks accelerating adverse selection in the core payer segment—precisely where MCR gains are claimed. This could turn the 2027 rate tailwind into a utilization headwind faster than models assume.
"The current valuation ignores the existential risk of a DOJ-mandated breakup of the Optum-UnitedHealthcare vertical integration."
Grok is right to worry about adverse selection, but let's look at the capital allocation risk. UNH is essentially paying for these margins via share buybacks while the DOJ antitrust cloud hangs over the Optum-UnitedHealthcare vertical integration. If the DOJ forces a divestiture, the 'Optum synergy' narrative collapses, and the P/E multiple will compress sharply. Investors are ignoring that the current valuation assumes a status quo that the regulatory environment is actively trying to dismantle.
"Adverse selection from member shedding poses a nearer-term earnings cliff than DOJ divestiture risk."
Gemini's divestiture risk is real, but the timing assumption is loose. DOJ antitrust cases move slowly—UNH likely has 18–36 months of operational runway before any forced breakup. The more immediate threat is Grok's adverse selection spiral: if Optum's 700k patient loss skews sicker in the core MA book, the 86.7% MCR could reverse faster than a regulatory decision would force divestiture. That's a 2026–2027 risk, not 2028.
"Durable margin depends on the Optum patient mix behind the 700k loss; 3–4 quarters of actual mix and utilization data will tell us whether the 86.7% improvement is durable or a near-term mirage."
To Grok: adverse selection could bite, but the key constraint is the patient mix behind Optum’s 700k loss. If exits are low-cost/low-utilization, MCR gains may persist; if they’re sicker or MA-heavy, utilization could rebound and margins compress well before any DOJ action. The timeline matters—3–4 quarters of actual mix and utilization data will tell us whether the 86.7% improvement is durable or a near-term mirage.
UNH's Q2 results showed operational progress, but persistent risks include regulatory scrutiny, potential adverse selection, and the sustainability of margin improvements.
