CENTENE CORPORATION REPORTS SECOND QUARTER 2025 RESULTS

ST. LOUIS, July 25, 2025 -- Centene Corporation (NYSE: CNC) (the Company) announced today its financial results for the second quarter ended June 30, 2025. In summary, the 2025 second quarter results were as follows:

"We are disappointed by our second quarter results, but we have a clear understanding of the trends that have impacted our performance, and are working with urgency and focus to restore our earnings trajectory," said Chief Executive Officer of Centene, Sarah M. London. "Despite the shifting landscape, we believe that the staying power of Medicaid, Medicare and the Individual Marketplace is as strong as it has ever been. Centene has significantly fortified our platform in service of these programs over the last three years, and as we move forward, we are focused on continuing to adapt with the market to deliver meaningful value to our members, our stakeholders and our shareholders over the long term."

•Since May, Centene and its Missouri subsidiary, Home State Health, have been supporting the St. Louis community impacted by tornadoes through donations as well as volunteer hours. In June, WellCare of Kentucky announced relief efforts to support communities impacted by the tornadoes in Eastern Kentucky. WellCare, with additional funding from the Centene Foundation, will support housing and rebuilding, disperse financial assistance, and provide basic supplies to help people recover.

•In June, Centene was named one of Newsweek's America's Greatest Workplaces for the third consecutive year. The recognition is based on employee feedback about company culture, leadership, integrity, compensation, work-life balance, and more. In May, the Company was also named to Becker's 150 Top Places to Work in Healthcare and to Newsweek's America's Greatest Workplaces for Gen Z 2025, for the second consecutive year.

•In May, Health Net and the Centene Foundation announced grants to expand healthcare services to underserved Californians through mobile health clinics. The investment is part of Health Net's new Mobile Outreach for Value, Equity and Sustainability (MOVES) program that targets rural or resource-limited areas and will help deliver preventative care, health education, and social services directly to neighborhoods facing barriers to traditional healthcare access.

The following table sets forth membership by line of business:

The following table sets forth supplemental revenue information ($ in millions):

•For the second quarter of 2025, premium and service revenues increased 18% to $42.5 billion from $36.0 billion in the comparable period of 2024. The increase was primarily driven by premium and membership growth in the PDP business along with overall market growth in the Marketplace business, and rate increases in the Medicaid business, partially offset by lower Medicaid membership as a result of redeterminations and lower Marketplace net risk adjustment revenue. The three months ended June 30, 2024, benefited from outperformance in Marketplace risk adjustment for the 2023 benefit year.

•Health benefits ratio (HBR) of 93.0% for the second quarter of 2025 represents an increase from 87.6% in the comparable period in 2024. The increase was primarily driven by a reduction in the Company's net 2025 Marketplace risk adjustment revenue transfer estimate, increased Marketplace medical costs, higher medical costs in Medicaid driven primarily by behavioral health, home health and high-cost drugs, and an increase to the 2025 Medicare Advantage premium deficiency reserve based on the progression of earnings during the year (with higher earnings at the beginning of the year and lower at the end of the year, given cost sharing progression).

•The SG&A expense ratio was 7.1% for the second quarter of 2025, compared to 8.0% in the second quarter of 2024. The adjusted SG&A expense ratio was 7.1% for the second quarter of 2025, compared to 8.0% in the second quarter of 2024. The decreases were primarily driven by continued leveraging of expenses over higher revenues and growth in the PDP business. The decreases were partially offset by growth in the Marketplace business, which operates at a meaningfully higher SG&A expense ratio as compared to the overall company.

•The income tax expense recorded in the second quarter of 2025 reflects the year-to-date impact of a lower estimated full year 2025 effective tax rate.

•Diluted loss per share was $(0.51) for the second quarter of 2025 driven primarily by a reduction in the Company's net 2025 Marketplace risk adjustment revenue transfer estimate.

•Cash flow provided by operations for the second quarter of 2025 was $1.8 billion, primarily driven by improved pharmacy rebate remittance timing.

At June 30, 2025, the Company had cash, investments and restricted deposits of $37.5 billion and maintained $234 million of cash and cash equivalents in its unregulated entities. Medical claims liabilities totaled $20.1 billion. The Company's days in claims payable (DCP) was 47 days, a decrease of two days as compared to the first quarter of 2025 driven by the timing and types of claims, as well as the impact of state-directed payments. Total debt was $17.6 billion, which included no borrowings on the $4.0 billion Revolving Credit Facility at quarter end.

The Company will provide 2025 earnings expectations on the conference call.

The Company is providing certain non-GAAP financial measures in this release as the Company believes that these figures are helpful in allowing investors to more accurately assess the ongoing nature of the Company's operations and measure the Company's performance more consistently across periods. The Company uses the presented non-GAAP financial measures internally in evaluating the Company's performance and for planning purposes, by allowing management to focus on period-to-period changes in the Company's core business operations, and in determining employee incentive compensation. Therefore, the Company believes that this information is meaningful in addition to the information contained in the GAAP presentation of financial information. The Company strongly encourages investors to review its consolidated financial statements and publicly filed reports in their entirety and cautions investors that the non-GAAP financial measures used by the Company may differ from similar measures used by other companies, even when similar terms are used to identify such measures. The presentation of non-GAAP financial measures is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with GAAP.

Specifically, the Company believes the presentation of non-GAAP financial measures that excludes amortization of acquired intangible assets, acquisition and divestiture related expenses, as well as other items, allows investors to develop a more meaningful understanding of the Company's core performance over time.

(4) The income tax effects of adjustments are based on the effective income tax rates applicable to each adjustment.

To provide clarity on the way management defines certain key metrics and ratios, the Company is providing a description of how the metric or ratio is calculated as follows:

•Health Benefits Ratio (HBR) (GAAP) = Medical costs divided by premium revenues.

•SG&A Expense Ratio (GAAP) = Selling, general and administrative expenses divided by premium and service revenues.

•Adjusted SG&A Expense Ratio (non-GAAP) = Adjusted selling, general and administrative expenses divided by premium and service revenues.

•Adjusted Effective Tax Rate (non-GAAP) = GAAP income tax expense (benefit) excluding the income tax effects of adjustments to net earnings divided by adjusted earnings (loss) before income tax expense.

•Adjusted Net Earnings (non-GAAP) = Net earnings less amortization of acquired intangible assets, less acquisition and divestiture related expenses, as well as adjustments for other items, net of the income tax effect of the adjustments.

•Adjusted Diluted EPS (non-GAAP) = Adjusted net earnings divided by weighted average common shares outstanding on a fully diluted basis.

•Debt to Capitalization Ratio (GAAP) = Total debt, divided by total debt plus total stockholder's equity.

•Average Medical Claims Expense (GAAP) = Medical costs for the period divided by number of days in such period. Average medical claims expense is most often calculated for the quarterly reporting period.

•Days in Claims Payable (GAAP) = Medical claims liabilities divided by average medical claims expense. Days in claims payable is most often calculated for the quarterly reporting period.

In addition, the following terms are defined as follows:

•State-directed Payments: Payments directed by a state that have minimal risk but are administered as a premium adjustment. These payments are recorded as premium revenue and medical costs at close to a 100% HBR. In many instances, the Company has little visibility to the timing of these payments until they are paid by a state.

•Pass-through Payments: Non-risk supplemental payments from a state that the Company is required to pass through to designated contracted providers. These payments are recorded as premium tax revenue and premium tax expense.

This list of important factors is not intended to be exhaustive. We discuss certain of these matters more fully, as well as certain other factors that may affect our business operations, financial condition, and results of operations, in our filings with the SEC, including our annual report on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K. Due to these important factors and risks, we cannot give assurances with respect to our future performance, including without limitation our ability to maintain adequate premium levels or our ability to control our future medical and selling, general and administrative costs.

The changes in medical claims liability are summarized as follows (in millions):

Centene's claims reserving process utilizes a consistent actuarial methodology to estimate Centene's ultimate liability. Any reduction in the "Incurred related to: Prior periods" amount may be offset as Centene actuarially determines the "Incurred related to: Current period." Additionally, approximately $124 million was recorded as a reduction to premium revenues resulting from development within "Incurred related to: Prior periods" due to minimum HBR and other return of premium programs.

The amount of the "Incurred related to: Prior periods" above represents favorable development and includes the effects of reserving under moderately adverse conditions, new markets where we use a conservative approach in setting reserves during the initial periods of operations, receipts from other third party payors related to coordination of benefits and lower medical utilization and cost trends for dates of service June 30, 2024, and prior.
