Founded in 1984 in St. Louis, Missouri and now headquartered in St. Louis, Centene serves approximately 27 million members across all 50 states through its subsidiaries including WellCare, Ambetter, and other regional health plans. The company is listed on the NYSE and generates approximately $145-150 billion in annual revenue. Centene grew rapidly through acquisitions and organic growth in the Medicaid managed care market, which expanded dramatically after the ACA. The company's acquisition of WellCare Health Plans in 2020 for $17.3 billion was transformative, making Centene the dominant Medicaid and Medicare managed care organization nationally. Centene's business model involves winning government contracts to manage healthcare for low-income and government-program members, earning a per-member-per-month capitation rate. In 2025, Centene navigates a challenging Medicaid environment following the unwinding of pandemic-era continuous enrollment provisions, which resulted in significant Medicaid membership losses as states re-verified eligibility. The company has been restructuring its cost base and shedding businesses (including an international JV) to focus on its core US government programs business. Centene competes with UnitedHealth Group's Medicaid division, Molina Healthcare, and Elevance Health for state Medicaid contracts. The company's 2025-2026 strategy centers on returning to enrollment growth as Medicaid redeterminations stabilize and Medicare Advantage continues expanding. ## Frequently Asked Questions ### What is Centene Corporation?
