UnitedHealth Surprises Wall Street and Signals Turnaround

UnitedHealth delivered a type of result in the second quarter that investors did not expect to see so soon. The net income was $5.48 billion, equivalent to $6.04 per share, against a market projection of $4.91. The loss ratio, the most closely watched metric in the healthcare sector, was 86.7%, nearly two percentage points below the 88.4% estimated by analysts.

The numbers were strong enough for the company to revise its annual guidance. The earnings per share expectation rose from $18.25 to a range between $19.50 and $20, a significant jump for a company valued at $392 billion. The shares opened up more than 10% on the day of the announcement and continue on a positive trajectory.

What stands out is not just the number itself, but what is behind it. UnitedHealth comes from one of the worst moments in its recent history, and the speed of recovery says a lot about how large American corporations are using operational restructuring and artificial intelligence to restore margins.

To understand the extent of the turnaround, it is necessary to go back to the problem. UnitedHealth is one of the largest operators of Medicare Advantage, a U.S. government health program primarily aimed at the elderly. For years, the company aggressively grew in this segment, expanding its beneficiary base and its network of doctors through Optum, its health services vertical.

The problem came on two simultaneous fronts. On one side, beneficiaries began to use more consultations, exams, and procedures than the company had projected, raising medical costs. On the other, the U.S. government tightened oversight on payments made to program operators and slowed the growth rate of reimbursements.

The result was a devastating combination: rising costs and slowing revenue. Shares plummeted. Then-CEO Andrew Witty resigned in May of last year amid pressure from investors and results that were consistently below expectations. For those following the American financial market, the deterioration of UnitedHealth became one of the most emblematic cases of regulatory risk in the healthcare sector.

The choice to replace Witty was Stephen Hemsley, who had previously been CEO of UnitedHealth and was serving as chairman. Hemsley took over with a clear mandate: to reverse the Medicare Advantage operation and cut whatever was necessary to restore profitability.

He replaced much of the senior leadership, reduced the extensive network of doctors at Optum, and, in a move that contradicts years of expansionist strategy, decreased the number of beneficiaries in the main Medicare plans. The logic is straightforward: it is better to have fewer clients and make money than to have many and lose.

The changes in plan design were also significant. The company replaced fixed copayments with coinsurance models, in which beneficiaries bear a percentage of the cost of procedures. This transfers part of the risk to the user and, at the same time, tends to reduce excessive use of services, as we have shown in previous analyses of the healthcare sector.

CFO Wayne DeVeydt acknowledged that the first signs of recovery appeared in the first quarter but gained traction in the second. "We saw some signs of recovery that were very encouraging and proved consistent in the following months," he stated in a call with analysts.

One of the most relevant aspects of UnitedHealth's recovery is the role of artificial intelligence. The company is investing more than $1.5 billion this year in AI, focusing on two fronts: detecting inappropriate payments and combating the use of AI by companies that bill medical expenses irregularly.

According to the CFO, the company was able to identify "unusual anomalies" in payments using AI tools. This is a concrete case of how artificial intelligence is being applied to generate measurable financial results, not just as a promise of future efficiency.

The $1.5 billion investment in AI may seem high in absolute terms, but for a company with quarterly revenue in the tens of billions of dollars, the return justifies itself quickly if the loss ratio falls by two percentage points. The difference between 88.4% and 86.7% in medical loss ratio, in an operation the size of UnitedHealth, represents billions of dollars in annual savings.

David Wagner, manager of Aptus Capital and shareholder of UnitedHealth, summarized the market sentiment by saying that the numbers "are a great reminder that this could be a turnaround story much faster than most believed."

For Brazilian investors following the healthcare sector, the case brings applicable lessons. Operators like Hapvida and SulAmérica face similar challenges of high loss ratios and regulatory pressure in Brazil. The scale difference is enormous, but the operational logic is the same: utilization control, repricing of plans, and the use of technology to reduce fraud and inefficiencies.

The case of UnitedHealth also reinforces a thesis that has been gaining traction among analysts: companies that can implement AI in a practical way focused on cost-cutting, rather than just announcing generic partnerships, tend to be disproportionately rewarded by the market. The more than 10% rise on the day of the announcement reflects exactly that.

With the revision of guidance and the consistency of quarterly results, UnitedHealth moves out of the "crisis company" category and into the "turnaround in progress" category. For the second half of the year, the central question is whether the trend of improvement in the loss ratio is sustainable or if there was some favorable seasonal effect. The answer will come in the next earnings reports.
