Centene sells health insurance, mostly to people covered by government programs like Medicaid and Medicare.
Centene is a health insurance company that mostly doesn't sell to you or your employer. It sells to governments — states and the federal government — which pay Centene to cover people on Medicaid (health care for lower-income families), Medicare (health care for seniors), and the individual insurance marketplaces set up under the Affordable Care Act. So the customer paying the bills is often a state agency, not a person writing a check. It's one of the biggest players in government-backed health coverage in the United States, and its headquarters in St. Louis mostly matters because it operates plans in dozens of states, each with its own rules.
Think of it as the company that runs the plumbing behind a lot of government health care: states decide who qualifies for help, and Centene takes on the job of actually arranging and paying for that care. Its main business by far is Medicaid, which brings in roughly two-thirds of its revenue, with Medicare and the commercial marketplace plans making up most of the rest. It makes money by collecting premiums (per-member payments) and then trying to spend less on medical care than it takes in — that gap is its profit. If members get sicker or care costs jump, that gap shrinks fast.
The last few years have been a bumpy ride. During the pandemic, states couldn't easily kick people off Medicaid, so Centene's rolls swelled. When that rule ended, millions of people got re-checked for eligibility and many lost coverage, which shrank Centene's membership and revenue. On top of that, Centene spent years selling off side businesses — pharmacy operations and overseas units — to refocus on its core insurance plans and pay down debt, a cleanup that has helped steady the ship. The big ongoing risks are government policy and rate-setting: states decide how much they'll pay Centene, and if costs run hotter than expected, margins get squeezed. When profits are good, the company tends to reinvest in its plans, pay down debt, and buy back its own stock.
