Company Snapshot
Centene Corporation provides managed healthcare services, including Medicaid, Medicare, commercial health plans, specialty pharmacy, and ancillary health services.
The company generates revenue primarily through government-subsidized programs by managing care for under-insured and uninsured populations, leveraging contracts with state agencies and commercial organizations.
Centene’s main customers are state governments, correctional facilities, employer groups, and individuals eligible for Medicaid, Medicare, and related health programs.
Centene Corporation is a leading healthcare enterprise focused on delivering managed care solutions for government-sponsored and commercial health programs across the United States. With a diversified portfolio spanning Medicaid, Medicare, and specialty services, the company leverages scale and expertise to serve complex and underserved populations.
Foolish take
Centene is a big provider of Medicaid services, but marketplace plans made possible by the Affordable Care Act (ACA) are also a significant part of its business. At the end of June, 21% of Centene’s total membership roster was made up of marketplace plan members.
Enhanced premium tax credits introduced in 2021 are set to expire at the end of 2025. Since the enhanced credits were introduced, enrollment in marketplace plans has more than doubled from 11 million to over 24 million people.
If those credits are allowed to expire, Centene could lose a lot of business. According to the Kaiser Family Foundation, a family of four trying to get by on $75,000 annually will see their premium payments more than double to reach about $489 per month.
This year, Centene expects adjusted earnings to come in at about $1.75 per share. That’s down from an estimate of $7.25 per share that it announced earlier this year. With earnings in freefall, it’s probably best to watch this stock’s story play out from a safe distance.
