CAUTIONARY STATEMENT ON FORWARD-LOOKING STATEMENTS

All statements, other than statements of current or historical fact, contained in this filing are forward-looking statements. Without limiting the foregoing, forward-looking statements often use words such as "believe," "anticipate," "plan," "expect," "estimate," "intend," "seek," "target," "goal," "may," "will," "would," "could," "should," "can," "continue," and other similar words or expressions (and the negative thereof). Centene Corporation and its subsidiaries (Centene, the Company, our or we) intends such forward-looking statements to be covered by the safe-harbor provisions for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995, and we are including this statement for purposes of complying with these safe-harbor provisions. In particular, these statements include, without limitation, statements about our future operating or financial performance, market opportunity, value creation strategy, competition, expected activities in connection with completed and future acquisitions and dispositions, our investments, and the adequacy of our available cash resources. These statements may be found in the various sections of this filing, such as Part I, Item 2. "Management's Discussion and Analysis of Financial Condition and Results of Operations," and Part II, Item 1. "Legal Proceedings."

These forward-looking statements reflect our current views with respect to future events and are based on numerous assumptions and assessments made by us in light of our experience and perception of historical trends, current conditions, business strategies, operating environments, future developments, and other factors we believe appropriate. By their nature, forward-looking statements involve known and unknown risks and uncertainties and are subject to change because they relate to events and depend on circumstances that will occur in the future, including economic, regulatory, competitive, and other factors that may cause our or our industry's actual results, levels of activity, performance, or achievements to be materially different from any future results, levels of activity, performance, or achievements expressed or implied by these forward-looking statements. These statements are not guarantees of future performance and are subject to risks, uncertainties, and assumptions.

All forward-looking statements included in this filing are based on information available to us on the date of this filing. Except as may be otherwise required by law, we undertake no obligation to update or revise the forward-looking statements included in this filing, whether as a result of new information, future events, or otherwise, after the date of this filing. You should not place undue reliance on any forward-looking statements, as actual results may differ materially from projections, estimates, or other forward-looking statements due to a variety of important factors, variables, and events including, but not limited to:

our ability to design and price products that are competitive and/or actuarially sound including but not limited to any impacts resulting from Medicaid redeterminations;
our ability to maintain or achieve improvement in the Centers for Medicare and Medicaid Services (CMS) Star ratings and maintain or achieve improvement in other quality scores in each case that can impact revenue and future growth;

provider, state, federal, foreign, and other contract changes and timing of regulatory approval of contracts;
the expiration, suspension, or termination of our contracts with federal or state governments (including, but not limited to, Medicaid, Medicare, TRICARE, or other customers);
the difficulty of predicting the timing or outcome of legal or regulatory proceedings or matters, including, but not limited to, our ability to resolve claims and/or allegations made by states with regard to past practices, including at Centene Pharmacy Services (formerly Envolve Pharmacy Solutions, Inc. (Envolve)), as our pharmacy benefits manager (PBM) subsidiary, within the reserve estimate we previously recorded and on other acceptable terms, or at all, or whether additional claims, reviews or investigations will be brought by states, the federal government or shareholder litigants, or government investigations;

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 Securities and Exchange Commission (SEC), including our annual report on Form 10-K, other 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.

Non-GAAP Financial Presentation

The Company is providing certain non-GAAP financial measures in this report 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 presentation of this additional non-GAAP financial information 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 information that excludes amortization of acquired intangible assets and 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.

The tables below provide reconciliations of non-GAAP items ($ in millions, except per share data):

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

1. Organization and Operations

Basis of Presentation

The accompanying interim financial statements have been prepared under the presumption that users of the interim financial information have either read or have access to the audited financial statements included in the Form 10-K for the fiscal year ended December 31, 2022. The unaudited interim financial statements herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Accordingly, footnote disclosures that would substantially duplicate the disclosures contained in the December 31, 2022 audited financial statements have been omitted from these interim financial statements, where appropriate. In the opinion of management, these financial statements reflect all adjustments, consisting only of normal recurring adjustments, which are necessary for a fair presentation of the results of the interim periods presented.

Certain 2022 amounts in the consolidated financial statements and notes to the consolidated financial statements have been reclassified to conform to the 2023 presentation, including reclassifications related to the Company's new segment reporting structure as outlined below. These reclassifications have no effect on net earnings or stockholders' equity as previously reported.

Segment Reporting

In the first quarter of 2023, and in conjunction with the Company's updated strategic plan, executive leadership realignment, and corresponding 2023 divestitures, the Company has revised the way it manages the business, evaluates performance, and allocates resources, resulting in an updated segment structure comprised of (1) a Medicaid segment, (2) a Medicare segment, (3) a Commercial segment, and (4) an Other segment.

The Medicaid, Medicare, and Commercial segments represent the government-sponsored or subsidized programs under which the Company offers managed healthcare services. Specifically, the Medicaid segment includes the Temporary Assistance for Needy Families (TANF) program, Medicaid Expansion programs, the Aged, Blind, or Disabled (ABD) program, the Children's Health Insurance Program (CHIP), Long-Term Services and Supports (LTSS), Foster Care, Medicare-Medicaid Plans (MMP), which cover beneficiaries who are dually eligible for Medicaid and Medicare, and other state-based programs. The Medicare segment includes Medicare Advantage, Medicare Supplement, Dual Eligible Special Needs Plans (D-SNPs), and Medicare Prescription Drug Plans (PDPs), also known as Medicare Part D. The Commercial segment includes the Health Insurance Marketplace along with individual, small group, and large group commercial healthcare products. The Other segment includes the Company's pharmacy operations, vision and dental services, clinical healthcare, behavioral health, international operations, and corporate management companies, among others.

Accounting Guidance Not Yet Adopted

The Company has determined that there are no recently issued accounting pronouncements that will have a material impact on its consolidated financial position, results of operations, or cash flows.

2. Acquisitions and Divestitures

On January 5, 2023, the Company completed the divestiture of HealthSmart, its third-party health plan administration business.

On January 10, 2023, the Company signed and closed on a definitive agreement to divest Centurion, its prison healthcare business. During 2022, the Company recorded impairment charges related to goodwill and other current assets associated with the pending divestitures. The Company could receive up to an additional $35 million in cash based on the reprocurements of certain Centurion contracts. The Company will recognize the appropriate amount of contingent consideration related to the additional $35 million when realized or realizable.

On January 20, 2023, the Company completed the divestiture of Magellan Specialty Health for approximately $646 million in cash and stock, including an estimated working capital adjustment and recognized a pre-tax gain of $79 million. The stock consideration was subsequently sold in April 2023 for cash proceeds of $245 million. The Company could also receive up to an additional $150 million in cash and stock in 2024 based on certain 2023 performance metrics. The Company will recognize the appropriate amount of contingent consideration related to the additional $150 million when realized or realizable.

(1) Investments in equity securities as of March 31, 2023 primarily consisted of shares received as part of the Magellan Specialty Health divestiture consideration. These shares were subsequently sold in April 2023.

The Company's investments are debt securities classified as available-for-sale with the exception of equity securities, certain private equity investments and life insurance contracts. The Company's investment policies are designed to provide liquidity, preserve capital and maximize total return on invested assets with the focus on high credit quality securities. The Company limits the size of investment in any single issuer other than U.S. treasury securities and obligations of U.S. government corporations and agencies. As of March 31, 2023, 99% of the Company's investments in rated securities carry an investment grade rating by nationally recognized statistical rating organizations. At March 31, 2023, the Company held certificates of deposit, equity securities, private equity investments, and life insurance contracts, which did not carry a credit rating. Accrued interest income on available-for-sale debt securities was $141 million and $132 million at March 31, 2023 and December 31, 2022, respectively, and is included in other current assets on the Consolidated Balance Sheets.

The Company's residential mortgage-backed securities are primarily issued by the Federal National Mortgage Association, Government National Mortgage Association, or Federal Home Loan Mortgage Corporation, which carry implicit or explicit guarantees of the U.S. government. The Company's commercial mortgage-backed securities are primarily senior tranches with a weighted average rating of AAA and a weighted average duration of 4 years at March 31, 2023.

As of March 31, 2023, the gross unrealized losses were generated from 6,109 positions out of a total of 6,936 positions. The change in fair value of available-for-sale debt securities is primarily a result of movement in interest rates subsequent to the purchase of the security.

For each security in an unrealized loss position, the Company assesses whether it intends to sell the security or if it is more likely than not the Company will be required to sell the security before recovery of the amortized cost basis for reasons such as liquidity, contractual, or regulatory purposes. If the security meets this criterion, the decline in fair value is recorded in earnings. The Company does not intend to sell these securities prior to maturity and it is not likely that the Company will be required to sell these securities prior to maturity; therefore, the Company did not record an impairment for these securities.

In addition, the Company monitors available-for-sale debt securities for credit losses. Certain investments have experienced a decline in fair value due to changes in credit quality, market interest rates, and/or general economic conditions. The Company recognizes an allowance when evidence demonstrates that the decline in fair value is credit related. Evidence of a credit related loss may include rating agency actions, adverse conditions specifically related to the security, or failure of the issuer of the security to make scheduled payments.

Actual maturities may differ from contractual maturities due to call or prepayment options. Equity securities, private equity investments and life insurance contracts are excluded from the table above because they do not have a contractual maturity. The Company has an option to redeem at amortized cost substantially all of the securities included in the greater than ten years category listed above.

4. Fair Value Measurements

Assets and liabilities recorded at fair value in the Consolidated Balance Sheets are categorized based upon observable or unobservable inputs used to estimate fair value. Level inputs are as follows:
Level Input:Input Definition:
Level IInputs are unadjusted, quoted prices for identical assets or liabilities in active markets at the measurement date.
 
Level IIInputs other than quoted prices included in Level I that are observable for the asset or liability through corroboration with market data at the measurement date.
 
Level IIIUnobservable inputs that reflect management's best estimate of what market participants would use in pricing the asset or liability at the measurement date.
