What does it do?
UnitedHealth Group is the largest health insurance company in the United States. If your employer offers health insurance, there's a good chance UnitedHealth is the company actually paying your medical bills. Beyond insurance, they run Optum — a massive healthcare services arm that owns doctor's offices, surgery centers, and even a pharmacy benefit manager that decides which drugs your insurance will cover. Think of them as a one-stop shop that sits between you, your doctor, your pharmacy, and your employer.
UnitedHealth covers roughly 50 million Americans, making it a bellwether for the entire U.S. healthcare system — when medical costs rise or fall, UnitedHealth feels it first. The company has been under intense public and political scrutiny following the murder of its insurance CEO Brian Thompson in December 2024, which sparked a national conversation about insurance claim denials and healthcare affordability. Investors are watching closely because regulatory and reputational pressure could reshape how the company operates at scale.
How does it make money?
UnitedHealth makes money two main ways. First, through UnitedHealthcare, it collects insurance premiums from employers and government programs like Medicare and Medicaid, then profits on the difference between what it collects and what it pays out in medical claims — this is called the medical loss ratio. Second, through Optum, it earns fees for managing pharmacy benefits, running clinics, and selling data analytics software to hospitals and insurers. Total revenue hit $447.6 billion in the latest year, up from $400.3 billion the prior year, with net income of $12.1 billion.
Why do investors care?
The core growth story is that UnitedHealth keeps expanding Optum, which is higher-margin and less volatile than pure insurance. As America's population ages, more people enter Medicare Advantage — a government-funded private insurance plan where UnitedHealth is the dominant player — creating a built-in growth runway. For the thesis to work, medical cost inflation needs to stay manageable, government reimbursement rates need to hold up, and Optum needs to keep growing faster than the insurance side. If all three hold, UnitedHealth can compound earnings reliably for years.
