In mid-April 2025, UnitedHealth Group (UNH) reported its 1Q25 operating results, including a modest shortfall in expected earnings and lowered its 2025 earnings forecast by 12%. The company blamed accelerating medical costs and federal policy changes for their most profitable service line, Medicare Advantage. Market reaction was swift and savage. UNH stock lost more than 22% in a single day. In May, United fired its CEO, Sir Andrew Witty and withdrew its earnings guidance for 2025, with the stock declining another 15%. Witty was followed out the door two months later by President and CFO John Rex, heir-apparent to longtime Chairman Stephen Hemsley.
Turns out, UNH’s market capitalization trajectory presaged the collapse in UNH’s 2025 cashflow. UNH’s projected cashflow from operations is now expected fall to be half of its 2025 forecast- a breathtaking $16 billion shortfall. In multiple investor calls, the new/old CEO Stephen Hemsley and his new crew have not come remotely close to explaining where the $16 billion went. Struggling UnitedHealth Group is one gigantic smoking black box.
2024 was a nightmare year for the company, beginning with the massive Change Healthcare cyberattack in February and concluding with the brutal killing of their senior health insurance executive, Brian Thompson, in November. It is clear in hindsight that business fundamentals for UNH’s health insurance and care delivery businesses deteriorated sharply during 2024, and its senior leadership were scrambling to repair the damage.
Health insurers across the country are experiencing record operating challenges. However, UNH’s business model enhanced their vulnerability. UNH had spent $118 billion in just five years (2019-2023) buying profitable smaller companies, almost all of which ended up inside of their enormous Optum subsidiary. These acquisitions included: multi-specialty physician groups, ambulatory surgery and urgent care, business intelligence/business process outsourcing and claims management companies.
These businesses are closely intertwined with United’s legacy health insurance business. In order to reach estimated $445 billion in total 2025 UNH revenues, one has to eliminate $165 billion in intercompany revenue flows (Examples- purchases of services by Optum Health from its consulting arm, OptumInsight, or purchase of health services from Optum Health by United Healthcare, UNH’s insurance business).
The company’s nearly fifty year old health insurance business had been a reliable 5.5-6% operating margin generator. However, in 2025, it will produce only a 3% operating margin. However, UNH’s incremental revenues and earnings growth for the past decade have not come from health insurance, but have been produced by Optum, whose revenues were growing much faster than its health insurance business.
Several pieces of Optum have also been far more profitable than United Healthcare itself. Optum Health grew into a $100 billion business (before eliminations), and used to earn an 10% operating margin. In 2025, that margin will be more like 2.5%. Optum Insight, a $19 billion business (before eliminations), which used to earn a sizzling 28% operating margin will be lucky to earn 8% in 2025. The complex interpenetration of Optum and United Healthcare’s businesses makes it impossible to gauge the seriousness of the company’s operating problems.
Optum Health appears to be a major source of the smoke, but it is impossible to tell from the skimpy disclosures where exactly the fire is.
