This health insurer lost 2 million customers — and made $1.5 Billion anyway. Here’s how

When Centene Corporation reported its first-quarter results in late April, the numbers told two stories that seemed impossible to reconcile.

The St. Louis-based insurer had hemorrhaged customers, watching its Affordable Care Act marketplace membership collapse from 5.6 million to 3.6 million in just one year — a drop of roughly 2 million people. Yet the company posted $1.5 billion in net earnings, raised its full-year profit guidance, and saw its adjusted earnings per share jump to $3.37, well above what Wall Street expected.

How does an insurer make more money with fewer customers? The answer reveals a lot about who is still standing in the post-subsidy-cliff health insurance market — and who is paying for it.

The math of higher prices

The simplest explanation is that Centene raised premiums faster than members walked away. After the enhanced ACA subsidies expired on January 1, premium hikes across the industry averaged 20 to 26 percent. Centene’s revenue actually grew year-over-year, climbing from $46.6 billion to $49.9 billion in the quarter, even as its marketplace book shrank by more than a third. When prices rise enough, fewer paying customers can still mean more money on the top line — and after a punishing 2025 in which insurers were squeezed by high medical spending and an unfavorable member mix, those rate hikes flowed almost directly to the bottom line.

Who left, and who stayed

The more interesting story is in the composition of the customers who remained. When subsidies disappeared, the people most likely to drop coverage or downgrade to a cheaper Bronze plan were the young and healthy — exactly the customers insurers most want to keep. The people who held on tended to be older, sicker, and managing chronic conditions they couldn’t afford to leave untreated.

Insurers call this “adverse selection,” and you can see it directly in Centene’s numbers. The company’s commercial Health Benefit Ratio — the share of premium dollars paid out in medical claims — came in at 75.3 percent, slightly above expectations, reflecting what executives politely called “higher acuity” among remaining members. Translation: the people still in the pool are using more care. But because Centene priced its 2026 plans assuming exactly that, the math still worked.

An industry-wide pattern

Centene isn’t alone. UnitedHealth, Elevance Health, and other major managed-care companies have leaned on the same playbook: raise prices, accept a smaller but more predictable membership base, and lean on the ACA’s risk-adjustment mechanism — which transfers funds from insurers with healthier members to those with sicker ones — to smooth out the rough edges. Analysts at the consultancy Wakely estimate that 14 percent of ACA enrollees missed their January 2026 premium payments, and the marketplace could shrink by as much as 26 percent by year-end. Wall Street, however, has largely cheered the discipline. After a brutal 2025, investors wanted to see margins — and they got them.

What it means for you

For consumers, Centene’s quarter is a reminder that the insurance market and the household budget often move in opposite directions. The same conditions that produced record profits — premium increases, narrower benefits, sicker risk pools — are the ones squeezing your wallet. If you’re still on a marketplace plan, the practical takeaways are familiar but worth repeating: shop carefully during open enrollment rather than auto-renewing, run the numbers on Bronze plans paired with a Health Savings Account, and watch your modified adjusted gross income closely, since one extra dollar above the 400 percent federal poverty level threshold can wipe out your subsidy entirely.

The cliff was supposed to hurt insurers. So far, it’s hurting the rest of us.
