Notice of 2023 Annual Meeting of Stockholders and Proxy Statement Our Purpose Transforming the health of the community, one person at a time. Since its founding as a single local healthcare plan in 1984, Centene’s heart and soul has been linked to the health of the communities we serve. From that day until now, Centene has worked tirelessly to fulfill needs in healthcare and help more individuals. As we go about our work today, this long-held commitment to the lives of children, families, seniors, people with disabilities and many more is encapsulated in our purpose: Transforming the health of the community, one person at a time. Our Values Focus on the Individual Whole Health Empowering people to create and maintain lifelong healthy habits Delivering a full spectrum of care from physical health to emotional wellness Active Local Involvement Helping our neighbors create stronger, healthier communities Letter from our CEO and our Chairman 3 Letter from our CEO and our Chairman March 24, 2023 Dear Stockholders: Centene has always believed our work has the potential to transform lives and build healthier communities. Centene was founded on the principle that everyone should have access to high-quality, affordable health care, regardless of age or economic condition. From this principled beginning, Centene has grown to be the leading provider of coverage through government-sponsored programs. We now serve 27 million members across America–primarily those who have been underserved, those with medically complex needs, and frankly, those whose voices too often go unheard. We deliver health care locally through mission-driven employees who reside and are deeply engaged in the communities they serve. Because of this incredible growth, we're now able to combine our on-the-ground insight with the vast experience, data and capabilities of a leading private-sector health care company. That means even more potential to drive meaningful change and improve access for those who remain unable to get the care they deserve. And so that’s been the central inspiration for the organization this past year: evolving the company to seize this new potential, while continuing to deliver for our members and shareholders. A Year of Progress and Change During 2022, Centene took important steps toward operational and cultural transformation and delivered a strong financial performance. Centene committed to a long-term strategy centered on growing from strength and focusing on our three core business- lines: Medicaid, Marketplace and Medicare. Government spending is expected to be the key driver of overall health care spending for the foreseeable future, and our unparalleled expertise serving lower income and complex populations uniquely positions Centene to harness this opportunity. We are positioned to drive significant earnings growth in 2023, demonstrating the power of our core businesses as we draw from positive enterprise momentum generated in 2022. To increase that momentum further, we have emphasized, and will continue to emphasize, operational efficiency and simplicity. We executed on our Value Creation plan, successfully advancing several key initiatives that are fortifying our company’s foundational strengths and reducing complexity across the enterprise. This pivotal work will position us for 2023 and beyond, as we enable the enterprise to better leverage Centene’s capabilities and scale. Thus, Centene enters 2023 with a clearly defined operational focus, a long-term growth algorithm, providing an important standard against which our businesses can be measured over time, and a stronger position from which to navigate the opportunities and challenges 2023 will bring. These include the long-awaited return of Medicaid redeterminations as state partners revisit beneficiary rolls to verify member eligibility. Centene will also manage through the fortification of our Medicare platform as we chart a course toward Medicare Stars scores improvement. As we have shared with investors, these transient dynamics will temper Centene’s earnings power in the near term - most notably in 2024. Simultaneously, we will continue to invest to modernize our infrastructure through selective automation, clinical model standardization and platform consolidation. With this strategy and approach, Centene will emerge with an improved growth trajectory and more enterprise earnings power. Our core businesses will be stronger and more efficient through the deliberate and methodical work outlined in our strategic plan. Members will directly benefit from better service and sharpened capabilities. 4 Centene Corporation Environmental, Social, Health, and Governance Enhancements Centene also made significant enhancements to the company’s governance structure in 2022, to ensure we have the right perspectives and processes to drive this long-term strategy. The company added five new board members since January 2022, and each of our new directors brings impactful insights and experience. We also reduced the number of board committees from seven to four and refreshed the chairmanships of each of the four committees over the past 18 months. Additionally, we listened to our stockholders and conducted a second stockholder meeting in September to declassify the board and implement several other new measures, such as the right to call a stockholder meeting and the right to act by written consent. As a result of these and other actions taken during the past year, Centene has meaningfully modernized its governance structure and continues to move toward best-in-class status as a responsive, stockholder conscious enterprise. Environmental factors contribute to our members’ ability to achieve their best possible health outcomes, so we worked to strengthen our transparency and impact in this area. We implemented enhanced processes and controls to increase our greenhouse gas emissions disclosures to include those within our value chain. We continued to invest in reducing our own carbon footprint, including through a waste reduction program that diverted a million pounds of waste from landfills. We further invested in our communities’ future by continuing to build the workforce we’ll need to best serve our members. At the center of Centene’s strategic plan is a continued focus on diversity of talent, community impact, supplier diversity and stakeholder collaboration. We aim to attract talent that reflects the diversity of our nation, grow leaders and leadership skills, and reward performance. Today, 77% of Centene’s workforce identify as women, 48% identify as people of color, and 11% identify as individuals with disabilities. Further, women make up 66% of employees at the supervisor or above level, and 18% of our employees participate in at least one of the company’s five Employee Inclusion Groups. We are proud of these statistics, and we believe the diversity of experience and viewpoints is an important driver of Centene’s success. For these values and more, Centene was named a 2023 Fortune Most Admired Company and was named to the 2023 Bloomberg Gender-Quality Index, among other prestigious honors. While we are proud of our diverse workforce and actions to advance health equity and positive community impact, we must continue to evolve and advance these efforts across the company and in our local communities. Anchored in Mission Through all the evolution, there is one cornerstone of Centene that will never change: our mission-driven culture. In 2022 our more than 70,000 employees showed up for the communities we serve in extraordinary ways. When natural disasters occurred, local teams supported our state partners in the immediate aftermath and beyond. Centene employees stepped up to bolster recovery efforts during Hurricane Ian in Florida and amid the November wildfires and flash flooding in California. They made sure our members could access essential services and prescription drugs, utilizing Centene’s uniquely local presence on behalf of those in need. Centene also made community investments to strengthen initiatives focused on health care access, education, and social services for our members. The Centene Charitable Foundation and its Texas health plan, Superior HealthPlan, committed to invest $7.9 million in a multipurpose community center in Uvalde, Texas following the devastating events that took 21 lives in that community, including the lives of 19 children. In partnership with Community Health Development, Inc., a federally qualified health center, the soon-to-be-built community center will serve as a whole health resource for the entire Uvalde community and its surrounding region. Letter from our CEO and our Chairman 5 And on May 14th, when shots rang out in the aisle of a neighborhood grocery store in downtown Buffalo, our extraordinary colleagues at Fidelis Care in New York State sprang into action. Within 24 hours, Fidelis employees mobilized to distribute food and needed supplies into a community whose only grocery store was surrounded in police tape. With the neighborhood pharmacy inside the Topp’s Grocery Store suddenly closed, our locally based team identified and called–within 72 hours of the shooting—every one of the 373 members who had filled prescriptions at that pharmacy in the preceding months to make sure they had needed medication. That’s the power of Centene’s mission. Centene employees are not only empowered to engage in simple, but profound, acts of human caring, but people who are drawn to these acts of service are similarly attracted to work for a company whose purpose aligns with their own. In Memoriam Finally, the Centene family experienced profound loss in 2022 with the passing of Michael Neidorff, our long-tenured former CEO. Michael’s loss will long be felt by the many whose lives he touched. His contribution to Centene and to health care in our country is the foundation upon which Centene’s leadership team is committed to building new and innovative platforms to provide high-quality, affordable health care to lower income and medically-complex populations for decades to come. Centene is grateful to him for this strong foundation, his leadership, and his commitment to the underserved in America. We are also grateful for the support of our many shareholders and look forward to the year ahead as we work to seize the powerful opportunities ahead that can differentiate Centene in the future. It’s a transformative time in our history and we’re energized by the opportunity to show up for our members, state partners and other stakeholders, all while enhancing our ability to generate shareholder return. In 2023, we’ll continue to focus on evolving the company to meet the moment we’re in, so that we can realize our full potential to transform health care. Thank you for your continued support of Centene and its essential mission. Sincerely, Sarah London Chief Executive Officer H. James Dallas Chairman of the Board 6 Centene Corporation Notice of 2023 Annual Meeting of Stockholders Time and Date 10:00 AM, Central Time, on Wednesday, May 10, 2023 Place Centene Plaza 7700 Forsyth Boulevard St. Louis, Missouri 63105 Centene Auditorium Record Date Stockholders as of March 13, 2023 are entitled to vote Voting Items Proposal Board Vote Recommendation For Further Details (1) To elect ten directors to hold office until the 2024 Annual Meeting of Stockholders or until their successors are duly elected and qualified; FOR each director nominee (2) To cast a non-binding advisory vote on the compensation of the Company’s Named Executive Officers; FOR Page 21 Page 69 (3) To cast a non-binding advisory vote on how frequently we should provide our stockholders with a Say-on-Pay vote; (4) To ratify the appointment of KPMG LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023; (5) To consider the stockholder proposal for shareholder ratification of termination pay, if properly presented at the Annual Meeting; and (6) To consider the stockholder proposal for maternal morbidity reduction metrics in executive compensation, if properly presented at the Annual Meeting.

Execution of Strategy Our growth over the past decade has positioned us to be a leader in the healthcare industry during this remarkable time, enabling the Company to stay focused on its mission while also delivering strong financial performance for its stockholders. Centene has a unique and powerful platform, and we are working to fortify its foundation to fuel our next phase of innovation and growth. We are focused on strong, long-term growth grounded in our core product lines, investing in becoming easy to work with by building modern systems and processes, and curating an enhanced network of best-in-class partnerships designed to drive value across our portfolio. The Value Creation Plan we initiated in 2021, which includes cost savings, gross margin expansion, and portfolio optimization and strategic capital allocation, supports the execution of this strategy — all aimed at delivering value to our stockholders. We achieved key milestones in our Value Creation Plan in 2022. Who We Are 9 Value Creation: Measuring Progress in 2022 The Company’s Approach to Integrating Technology and Healthcare We have the opportunity to lead the digital transformation of healthcare and to create a seamless experience for our members and providers, closing the gap between health and care. Accordingly, we are investing in scalable innovation and transformation to harness our data. Our rich, local data amassed over decades allows us to track utilization trends, identify health disparities, monitor quality of care, and evaluate the effectiveness of our programs. Through these analyses, we identify and implement interventions that improve health outcomes, advance health equity and population health, and guide high-impact investments into the community. In this way, our data will enable us to transform the health of our communities long-term and deliver value to both members and stockholders. Additionally, we are investing to become easier to work with, in part by designing seamless experiences for our members, providers and government partners. Our goal is a lack of administrative friction, with operational and payment activities largely automated in the background. We believe that deeper innovation at Centene is a catalyst in the creation of a healthcare learning and discovery platform. It is through these innovative solutions that we plan to bring about a unique, personalized digital healthcare experience for each member to deliver better health outcomes. 10 Centene Corporation Commitment to Environmental, Social, Health, and Governance (ESHG) Since its founding as a single local healthcare plan in 1984, Centene has been focused on the health of the communities we serve. In alignment with our purpose of transforming the health of the community, one person at a time, we continue to center around the principles upon which our company was founded: focus on the individual, commitment to whole health, and active local involvement. These principles shape our focus on the environment, the health and social well-being of our communities, and our culture of ethics and governance. At Centene, we include “Health” as a key component of our Environmental, Social, and Governance (ESG) strategy. Our ESHG strategic framework expresses Centene’s commitments to Advancing Environmental Resilience, Serving Our Communities, Living Our Values, and Powering Better Health, all while identifying 16 key business areas essential to our success. Advancing Environmental Resilience • Environmental Impacts on Health • Environmental Sustainability Living Our Values • • • Ethics and Compliance Governance and Accountability Data Privacy and Security Serving Our Communities Powering Better Health • Community Outreach • • • • • Employee Partnership and Development Diversity, Equity and Inclusion Community Investment Community Engagement Employee Health and Well-Being • • • • • Healthcare Quality Healthcare Affordability Healthcare Access Research and Development Public Policy As the leader in government-sponsored healthcare, we hold a unique position to address the environmental, social, and health barriers that impact our most vulnerable populations. Continued focus on ESHG matters remains foundational to supporting our strategy, long-term sustainability, and value creation. As part of this focus, throughout the last year we have made several enhancements to our disclosures and reporting, including issuing reporting aligned with the Sustainability Accounting Standards Board (SASB) and the Task Force on Climate-related Financial Disclosures (TCFD). In addition, diversity, equity, and inclusion has remained a top priority for Centene. Our Diversity, Equity & Inclusion 2022 C-Index Annual Report includes our EEO-1 data and highlights our commitment to sustain and advance our vision of conscious inclusion of talent, community impact, supplier diversity, and stakeholder collaboration.

The 2022 plan design and awards resulted in 9% of base salary, 13% of target annual cash incentive plan, and 78% of target LTI for our current CEO and the following pay elements, metrics, and average target pay mix for all of our NEOs: 2022 Pay Elements Base Salary Award Type Mix Purpose Cash 14% To recognize individual contribution, time in role, scope of responsibility, leadership skills and experience. Annual Cash Incentive Plan Cash 17% Long-Term Incentive Awards Performance-based Restricted Stock Units (PSUs) Service-based Restricted Stock Units (RSUs) Performance-based Stock Options Cash Long-term Incentive Equity Equity Equity Cash To reward executives for performance on key operational and financial measures, with emphasis on individual contribution. To retain and motivate executives to drive long-term stockholder value and align their actions to drive successful business outcomes. 69% The performance-based stock options and cash long- term incentives were awarded in 2021 for many of our NEOs (prior to the Board and committee refreshment in 2022). Beginning in 2023, we will grant annual awards in March and eliminate performance based-stock options or cash long-term incentives. 18 Centene Corporation 2022 Annual Incentive Plan Funding Results Threshold % of Target 50% 2022 Adjusted Diluted EPS Target   100%   Maximum 200%  The Compensation and Talent Committee (Compensation Committee) exercised negative discretion on the Adjusted Diluted EPS metric and reduced the reported result of $5.78 by $0.02 for share repurchases not included in the annual operating plan and funded from free cash flow from operation. While the 2022 bonus plan provides for Adjusted Diluted EPS to fund the pool at 190%, the Compensation Committee exercised negative discretion and reduced the funding pool by 5% as a result of the quality metrics. 2020 - 2022 Performance-based Restricted Stock Unit Award Results Threshold Target Maximum Weight Metric Payout of Target Weighted Payout Pre-tax Margin (As adjusted) Compound Annual Revenue Growth Rate 60% 82.7% 49.6% 40% 132.0% 52.8% 100% 102.4% 2020 - 2022 Cash Long-term Incentive Plan Results Threshold Target Maximum Weight Metric Payout of Target Weighted Payout Pre-tax Margin (As adjusted) Compound Annual Revenue Growth Rate HCI Peer Group Relative TSR Percentile Rank 30% 82.7% 24.8% 20% 132.0% 26.4% 50% —% —% 100% 51.2% Proxy Summary 19 Compensation Best Practices The Compensation Committee establishes and administers the executive compensation philosophy and program and assists the Board of Directors in the development and oversight of all aspects of executive compensation. Presented in the table below are highlights of our compensation practices: What We Do  Pay for Performance A significant portion of our NEOs’ compensation is tied to performance with clearly articulated financial and performance goals.  Competitive Compensation Each component of the NEOs’ annual total direct compensation is generally targeted at the 50th percentile of peer group compensation. The Compensation Committee may consider differences from the median in certain cases.  Long-Term Incentive Awards Reward continuous performance on multiple metrics and vest at the end of a three-year period.  Formula Based Annual Incentive Plan Awards under the Annual Cash Incentive plan are formula based.  Tally Sheets Tally sheets and wealth accumulation analyses for each NEO are reviewed annually.  Annual Compensation Risk Assessment We regularly analyze risks related to our compensation program and we conduct broad risk assessments. What We Don’t Do    Excessive Risk-Taking in Our Compensation Programs The long-term incentive plans use multiple performance measures, capped payouts and other features intended to minimize the incentive to take overly risky actions.    No Tax Gross-ups There are no tax “gross-ups” for perquisites or excise tax gross-ups in the event of a change of control related termination.    No Single-Trigger Employment Agreements Any cash payments in executive employment agreements are subject to a “double-trigger” change in control condition.   Stock Ownership Requirements We maintain rigorous stock ownership requirements for our directors, executives and other members of senior management. Our CEO’s requirement is 5x annual base pay; other NEOs’ requirements are 2.5x annual base pay.   Clawbacks We can recover performance-based cash and equity incentive compensation paid to executives in various circumstances.   Independent Compensation Consultant The Compensation and Talent Committee retains an independent compensation consultant to advise the committee on executive compensation matters.   Executive Severance Arrangements The Compensation and Talent Committee reviews severance policies annually and limits the usage of one-off arrangements.  No Hedging or Pledging Directors and executives are prohibited from hedging, pledging or engaging in any derivatives trading with respect to Company stock.

The stockholders also have the opportunity at the Annual Meeting to cast a non-binding advisory vote on how frequently the Company should provide its stockholders with a Say-on-Pay vote (such as that provided above in Proposal Three). By voting on this proposal, stockholders may indicate whether they would prefer having a Say-on-Pay vote every one, two or three years, or they may abstain. 4 PROPOSAL Ratification of Appointment of Independent Registered Public Accounting Firm The Board recommends a vote FOR this proposal. See page 120 KPMG LLP audited our financial statements for the fiscal year ended December 31, 2022. The Audit and Compliance Committee has appointed KPMG LLP to serve as our independent registered public accounting firm for the current fiscal year, and we are asking stockholders to ratify this appointment. KPMG LLP has been retained as our external auditor continuously since 2005. 5 PROPOSAL 6 PROPOSAL Stockholder Proposal for Shareholder Ratification of Termination Pay See page 123 The Board recommends a vote AGAINST this proposal. Stockholder Proposal for Maternal Morbidity Reduction Metrics in Executive Compensation The Board recommends a vote AGAINST this proposal. See page 126 Proposal 1 – Election of Directors 21 1 PROPOSAL Election of Directors The first proposal on the agenda for the meeting is the election of ten nominees to serve for a one-year term beginning at the meeting and ending at our 2024 Annual Meeting of Stockholders. Pursuant to our agreement with Politan Capital Management, and our mandatory retirement age policy, Mr. Ayala, Mr. Gephardt and Mr. Trubeck are our current directors who are not standing for re-election. In light of these retirements, the Board has reduced the size of the Board to 10 directors, effective upon Messrs. Ayala’s, Gephardt’s and Trubeck’s retirements from the Board. No director, including any director standing for election, or any associate of a director, is a party adverse to us or any of our subsidiaries in any material proceeding or has any material interest adverse to us or any of our subsidiaries. No director, including any director standing for election, is related by blood, marriage, or adoption to any other director or any executive officer. The Board has nominated Jessica Blume, Kenneth Burdick, Christopher Coughlin, James Dallas, Wayne DeVeydt, Frederick Eppinger, Monte Ford, Sarah London, Lori Robinson and Theodore Samuels for re-election to the Board. We expect that all nominees will be able to serve if elected. If any of them are not able to serve, proxies may be voted for a substitute nominee or nominees or the Board may choose to reduce the size of the board. The Board believes the election of these ten nominees is in our best interests and the best interests of our stockholders and recommends a vote “FOR” the election of the ten nominees. 22 Centene Corporation Board Overview Director Qualifications We believe that our directors should understand the diverse populations we serve and possess the highest personal and professional ethics, integrity, and values and be committed to representing the interests of our stockholders. They must also have an inquisitive and objective perspective, practical wisdom, mature judgment and demonstrated leadership skills. We also endeavor to have a Board of Directors representing a range of experiences in areas that are relevant to the Company’s business activities. Below we identify and describe the key experience, qualifications and skills criteria we believe are important for our Board of Directors, as a whole, to possess. These are the criteria our Governance Committee considers when evaluating director nominees. Leadership Experience We believe that directors with experience in significant leadership positions over an extended period, especially chief executive officer positions, chief financial officers and other senior executives, provide the Company with valuable insights and strategic thinking. These individuals generally possess extraordinary leadership qualities and the ability to identify and develop those qualities in others. They demonstrate a practical understanding of organizations, processes, strategy, risk management and the methods to drive change and growth. Finance and Accounting Experience We believe that directors with experience in public accounting, investment banking and financial services companies possess an understanding of finance and the financial reporting process with which to manage our business. We measure our operating and strategic performance by reference to financial targets. In addition, accurate financial reporting and robust auditing are critical to our success and developing stockholders’ confidence in our reporting processes under the Sarbanes-Oxley Act of 2002. Healthcare and Insurance Industry Experience Our industry is complex and rapidly evolving. Healthcare and insurance industry experience includes expertise with healthcare operations, healthcare technology, insurance and other experience. Directors with industry experience help the Company stay abreast of industry best practices and innovations and help us to benchmark our practices against those of our competitors. Environmental, Social & Governance Experience and Community Involvement As a corporate citizen, we believe that sustainable operations are both financially and operationally beneficial to our business, and critical to the health of our employees and the communities in which we operate. We seek directors with experience in building strong environmental, labor, health & safety and ethical practices. Information Technology and Security Experience Because effective information systems and the integrity and timeliness of data we use to serve our customers and healthcare professionals are integral to the operation of our business, and because technology plays a central role in healthcare, including the diagnosis, management and treatment of disease, we seek directors with experience in relevant technology and who have experience managing cybersecurity and information security risks. Public Company Board and Governance Experience Directors with public company board experience understand the dynamics and operation of a corporate board, the relationship of a public company board to the Chief Executive Officer and other senior management personnel, the legal and regulatory landscape in which public companies must operate, the importance of particular agenda and oversight issues, and how to oversee an ever-changing mix of strategic, operational, and compliance-related matters. Proposal 1 – Election of Directors 23 Background & Experience Below we identify and describe the key experience, qualifications and skills our directors bring to the Board that are important considering the Company’s business and structure.

Our Board also embraces and encourages a culture of inclusion and diversity. We believe diversity of backgrounds, viewpoints and lived experiences ensures all perspectives are heard and considered and assists our Board in reaching the best decisions for the members we serve. While our Board does not establish specific gender and race/ethnicity goals or quotas with respect to diversity, the Board is committed to actively seeking women and racially/ethnically diverse director candidates as part of the process for selecting new Board members and adopted the “Rooney Rule” requiring that women and minorities be included in the initial pool of candidates when selecting new director nominees.

Mr. Dallas will remain a director of the Company, and is standing for reelection in 2023. 26 Centene Corporation 2023 Director Nominees We have ten nominees for the Board of Directors, all of whom serve on our current Board of Directors.

These nominees, their ages at the date of this Proxy Statement and the year in which they first became directors are summarized in the table below.

In its evaluation, the Board reviewed whether any transactions or relationships exist currently, or existed during the past three years, between each nominee and the Company or its subsidiaries, affiliates or independent auditors. The Board also examined whether there were any transactions or relationships between each nominee and members of the senior management of the Company or their affiliates. Based on this review and the NYSE’s definition of “independence,” the Board has affirmatively determined that all director nominees are independent as defined under the rules of the NYSE, except for Ms. London and Mr. Burdick due to their current or recent employment by the Company, as applicable. In addition, as disclosed under "Related Party Transactions", Mr. Burdick is the Chairman and CEO of LifeStance Health Group, Inc., to which the Company has made payments. The independent directors currently are Mr. Ayala, Ms. Blume, Mr. Coughlin, Mr. Dallas, Mr. DeVeydt, Mr. Eppinger, Mr. Ford, Mr. Gephardt, General Robinson, Mr. Samuels and Mr. Trubeck. The Board has also determined that each of the members of our Compensation and Talent Committee meet the enhanced independence requirements under the rules of the NYSE. The Board has also determined that each of the members of our Audit and Compliance Committee is “independent” for purposes of Rule 10A-3 under the Securities Exchange Act of 1934, as amended, and the NYSE’s listing requirements, and that each member is an “audit committee financial expert” as that term is defined by SEC regulations. The Board previously determined that Robert K. Ditmore, Leslie Norwalk, John R. Roberts, and Tommy G. Thompson, each of whom served on our Board during 2022, satisfied the independence requirements of the NYSE listing standards. In the course of the Board’s determination regarding the independence of each director nominee, it considered that Mr. DeVeydt is the executive chairman of Surgery Partners, Inc., with which the Company conducts business. The Board determined that the Company’s relationship with Surgery Partners, Inc. did not impact Mr. DeVeydt’s independence, including because the amounts paid by the Company to Surgery Partners, Inc. were below the thresholds of the NYSE listing standards. Accordingly, no director or director nominee, excluding Ms. London and Mr. Burdick, has a direct or indirect material relationship with us except for their role as a director or stockholder. Director Nomination Process In making its annual director nominations determination, the Board’s objective is to recommend a group of directors that can best ensure the continuing success of our business and represent stockholder interests through the exercise of sound judgment using its diversity of experience and perspectives. The Governance Committee recommends to the Board director candidates for nomination and election during the annual stockholders meeting or for appointment to fill vacancies. The Governance Committee works with our Board to determine the characteristics, skills, and experience for the Board as a whole and its individual members with the objective of having a board with diverse backgrounds, skills, and experience. The Board has adopted the "Rooney Rule," in which it will include diverse candidates in the interviewing process for a director role. The Board does not believe that directors should expect to be re-nominated annually. In determining whether to recommend a director for re-election, the Governance Committee considers the director’s tenure, participation in and contributions to the activities of the Board, the results of the most recent Board evaluation, meeting attendance and how the director’s experience, qualifications and skills complement the experience, qualifications and skills of the Board as a whole. When the Governance Committee recruits new director candidates, that process typically involves either a search firm or a member of the Governance Committee or Board contacting a prospect to assess interest and availability. A candidate will then meet with members of the Board and our Chief Executive Officer. At the same time, the Governance Committee and the search firm will contact references for the candidate. A background check is completed before a final candidate recommendation is made to the Board. Mr. Ford was initially identified by the search firm and his candidacy was recommended by the Governance Committee. Proposal 1 – Election of Directors 37 Stockholder Nominations of Director Candidates Stockholders may recommend individuals to the Governance Committee for consideration as potential director candidates by submitting their names, together with appropriate biographical information and background materials to Governance Committee, c/o Corporate Secretary, Centene Corporation, 7700 Forsyth Boulevard, St. Louis, Missouri 63105. Assuming that appropriate biographical and background material has been provided on a timely basis in accordance with the procedures set forth in our By-laws, the Governance Committee will evaluate stockholder-recommended candidates by following substantially the same process and applying substantially the same criteria as it follows for candidates submitted by others. 38 Centene Corporation Corporate Governance Corporate Governance Principles The Governance Committee developed and recommended to the Board a set of corporate governance guidelines, which the Board adopted. Our Corporate Governance Guidelines may be found on our website at www.centene.com. These guidelines include: a limitation on the number of boards on which a director may serve, qualifications for directors (including a requirement that directors be prepared to resign from the Board in the event of any significant change in their personal circumstances that could affect the discharge of their responsibilities), director orientation and continuing education, and a requirement that the Board and each of its Committees perform an annual self-evaluation. Our Governance Practices We strive to implement best practices in stockholder rights and strong corporate governance policies that promote the long-term interests of stockholders, strengthen Board and management accountability, and build on our environmental, social and governance leadership. We have enhanced our corporate governance framework over time based on input from our Board, stockholders and other governance experts. Our governance practices include: Stockholder Rights Annual Election of Directors. We have an unclassified Board. All directors are elected annually for one-year terms Majority Voting Uncontested Director Elections. Any director nominee must resign if they do not receive an affirmative vote of a majority of votes cast in an uncontested election. The Board will then determine whether to accept the resignation and disclose any decision not to accept the resignation Removal Rights. Stockholders can remove directors with or without cause Proxy Access. Up to 20 stockholders owning at least 3% of shares continuously for three years may nominate up to the greater of two individuals or 20% of our Board Special Meeting Rights. Stockholders owning at least 10% of our outstanding shares have the right to call a special meeting of the stockholders Action by Written Consent Rights. Stockholders have the right to act by written consent No Stockholder Rights Plan. We do not have a stockholder rights plan, commonly referred to as a “poison pill“ No Supermajority Vote Provisions. We do not have any supermajority vote provisions in our Articles of Incorporation or By-laws No Cumulative Voting. We have a single class of shares with equal voting rights Corporate Governance 39 In response to stockholder feedback, we made a number of changes to our Corporate Governance practices during 2022 as set forth below. Category What We Heard What We Changed Board Refreshment Long-tenured Lead Independent Director Appointed James Dallas as new Lead Independent Director in January 2022 Separate CEO and Chairman roles Separated CEO and Chairman roles in April 2022 Refresh Board Appointed Kenneth Burdick, Christopher Coughlin, Wayne DeVeydt and Theodore Samuels in January 2022 Appointed Monte Ford in November 2022 Average age of Board members reduced to 62 Average tenure of Board members reduced to 3.6 years Adopt retirement policy Adopted mandatory retirement policy at age 75 Enhance Stockholder Rights Declassify Board of Directors Stockholder special meeting rights Modernize Board Committees Stockholder written consent rights Improve stockholder proxy access rights Rotate membership of committees Refresh chairs of committees Reduce the number of committees Clarify roles of committees Declassified Board of Directors; all directors to stand for election annually beginning in 2023 Amended Certificate of Incorporation and By-laws to provide stockholders with 10% ownership the right to call a special meeting Amended Certificate of Incorporation and By-laws to provide stockholders the right to act by written consent Amended By-laws to shorten the proxy access ownership rights to 3 years Amended By-laws to shorten the advance notice window to 90 – 120 days Committee membership refreshed in January 2022 and in August 2022 All committees have refreshed their chairs since November 2021 Number of committees reduced from 7 to 4 in August 2022 Committee charters revised with responsibilities realigned in August 2022 40 Centene Corporation Board Practices Commitment to Board Refreshment. 80% of our directors have joined the Board in the last 3.5 years and have expanded the Board’s scope of experience Independent Board: 80% of the Director Nominees are independent Separate Chair of the Board and Chief Executive Officer. The Board has chosen to separate the roles of Chief Executive Officer and Chairman of the Board Independent Board Leadership. Our Chairman of the Board is a non-executive, independent director. Independent Board Committees. Each of the Audit and Compliance Committee, Compensation and Talent Committee, and Governance Committee is comprised entirely of independent directors “Rooney Rule” for Board Recruitment. The Board requires that women and minorities be included in the initial pool of candidates when selecting new director nominees Committee Charters. Each standing committee operates under a written charter that has been approved by the Board and is reviewed annually Executive Sessions. Independent directors meet regularly without management and non-management directors Mandatory Retirement Age. Mandatory retirement age of 75 provides regular opportunities for Board refreshment Limits on Public Company Directorships. To ensure directors are able to devote sufficient time and attention to their responsibilities as board members, directors may not serve on more than three boards of other public companies Continuing Education for Directors. The Board is regularly updated on the Company’s businesses, strategies, customers, operations and employee matters, as well as external trends and issues that affect the Company. Directors also are encouraged to attend continuing education courses relevant to their service on our Board Board and Committee Self-Evaluation Process. Our Board and committees conduct annual performance self-evaluations led by the chair of the Governance Committee, including one-on-one interviews Political Contributions Disclosures. We publicly disclose our political contributions and public advocacy efforts and the contributions of our federal and state political action committees Strong Codes of Ethics. Centene is committed to operating its business with the highest level of integrity and has adopted codes of ethics that apply to all directors and senior financial personnel, and a code of conduct that applies to all employees The Board continuously reviews our governance practices, assesses the regulatory and legislative environment, and adopts the governance practices that best serve the interests of our stockholders. Changes to Certificate of Incorporation and By-laws During the past few years, we have taken steps to enhance strong governance practices. At our Special Stockholder Meeting on September 27, 2022, our stockholders approved amendments to our Certificate of Incorporation to (i) immediately declassify the Board so that the terms of the Company’s directors end at the 2023 Annual Meeting of Stockholders and all director nominees will stand for election annually, (ii) remove the prohibition on stockholders calling special meetings and (iii) permit stockholders to act by written consent, subject to certain terms and conditions. We also amended our By-laws to permit stockholders holding 10% of our outstanding shares to call a special meeting. In addition, we also amended our By-laws to shorten the “proxy access” ownership requirement to three years and shorten the advance notice window to 90 – 120 days, each to align with market standards. Corporate Governance 41 We believe these changes will enhance our corporate governance practices that promote long-term interests of our stockholders and strengthen Board and management accountability. Proxy Access Proxy access allows stockholders who meet minimum stock ownership and holding period requirements, and who comply with specified procedural and disclosure requirements, the opportunity to include their director nominees in the Company’s proxy materials. We believe proxy access gives our long-term stockholders a valuable right and enables them to have an important voice in director elections. The following is a summary outlining key details of requirements related to our proxy access By-law: Ownership Threshold at least 3% of the Company’s outstanding common stock Group Ownership Ownership Period Number of Nominees a group of 20 or less holders at least 3 years of continuous ownership the greater of two individuals or 20% of the Board (not to exceed one-half of the number of directors up for election at the annual meeting) Board and Committee Structure Board Leadership Structure The Board determines the most suitable leadership structure from time to time. At present, the Board has chosen to separate the roles of Chief Executive Officer and Chairman of the Board. Sarah London is our Chief Executive Officer and H. James Dallas is our independent, non-executive Chairman of the Board. We believe this structure is optimal for Centene at this time because it allows Ms. London to focus on leading the organization while our Chairman focuses on leading the Board. Structure of Board of Directors Our Amended and Restated By-laws provide that our Board of Directors shall consist of five to fourteen directors, with the exact number of directors on the Board being fixed from time to time by resolution adopted by the affirmative vote of a majority of the total number of directors then in office. Currently, the Board is fixed at thirteen directors, with the Board size reduced to ten effective as of the 2023 Annual Meeting, with eight of the ten directors considered independent. H. James Dallas serves as non-executive independent Chairman of the Board. All ten members of the Board are standing for re- election to hold office until the 2024 Annual Meeting of Stockholders. 42 Centene Corporation Board Committees and Functions In response to stockholder feedback, we modernized our Board Committee structure and refreshed our Committee membership as described below. Category What We Heard What We Changed Modernize Board Committees Rotate membership of committees Refresh chairs of committees Reduce the number of committees Clarify roles of committees Committee membership refreshed in January 2022 and in August 2022 All committees have refreshed their chairs since November 2021 Number of committees reduced from 7 to 4 in August 2022 Committee charters revised with responsibilities realigned in August 2022 In August 2022, the Board evaluated its committee structure, including the number of committees, the functions of the committees and the composition of the committee membership, and determined to update its committee structure to better align with our business and operations and the mix of experience, qualifications and skills our directors bring to the Board. As a result of the review, the Board eliminated its Compliance Committee, Environmental and Social Responsibility (ESR) Committee, Government and Regulatory Affairs Committee and Technology Committee. The Board created a new Value Creation Committee, and reallocated oversight responsibilities of the eliminated committees to the remaining standing committees. Following the committee restructuring, the Board now has the following four standing committees: • Audit and Compliance Committee, with jurisdiction over financial statements and disclosures; controls and procedures (including information technology and cybersecurity controls and procedures); the independent auditor; oversight of risk management; reviews capital structure; compliance (specifically, the jurisdiction of the prior Compliance Committee); and those aspects of ESG that relate to financial reporting; • • • Compensation and Talent Committee, with jurisdiction over executive compensation; Governance Committee, with jurisdiction over director evaluation process; the Board and committee composition; succession planning; general environmental, social and governance matters (specifically, the jurisdiction of the prior ESR Committee, except for ESG issues related to financial reporting which are overseen by the Audit and Compliance Committee); government relations (specifically the jurisdiction of the prior Government and Regulatory Affairs Committee); and bi-annual review of the political activity report; and Value Creation Committee, with jurisdiction over value creation, technology (including cybersecurity strategy), digitalization, and quality and member experience (including Star ratings strategy). Our prior committees, the Compliance Committee, the Environmental and Social Responsibility Committee, the Government and Regulatory Affairs Committee and the Technology Committee each met twice prior to their dissolution on August 24, 2022. Corporate Governance 43 The table below shows membership as of March 24, 2023 in our standing committees and the number of meetings of each committee held in 2022.

The Compliance Committee, the Environmental and Social Responsibility Committee, the Government and Regulatory Affairs Committee and the Technology committee each met twice in 2022. During 2022, each of our directors attended at least 80% of the aggregate number of meetings of the Board and all committees held during the period in which the director served. Average meeting attendance by all current directors serving during 2022 was 93%. As stated in our Corporate Governance Guidelines, we believe it is important for the members of our Board to attend the annual meeting of stockholders. All directors who were members of the Board at the time of the 2022 annual meeting of stockholders attended the meeting. During each regularly scheduled Board and Committee meeting, and as appropriate during special meetings, the directors meet privately in executive session. During each regularly scheduled Board meeting, the non-management directors meet privately in executive session as well. Director Education and Orientation Program The Company provides an orientation and continuing education process for Board members to enable them to stay current on developments related to their Board and committee service. Educational opportunities may include seminars, presentations, relevant materials, meetings with key management, and/ or visits to Company facilities. The Governance Committee is responsible for reviewing the Company’s programs relating to director orientation and continuing education from time to time. New Director Orientation Continuing Education Shortly after joining the Board, the Company provides an in-person, high-touch, customizable orientation and onboarding experience. At the end of their orientation, new directors should: know key information about Centene’s business, vision, strategy, leaders, and organization; feel excited about joining the Board, welcomed and supported as a new director, and well-informed about their responsibilities and duties as directors and on any committees in which they serve; and have access to resources, information, and contacts that will enable them to be effective in their role. We joined the National Association of Corporate Directors and encourage our Board members to take advantage of its numerous educational resources and programs. The Company provides quarterly updates on continuing education opportunities and, pursuant to our director education policy, will reimburse Board members for the cost of any programs Board members attend as well as costs related to membership in relevant associations. Beyond the Boardroom Throughout their service, our directors have discussions with each other and senior leadership of the Company outside of regularly scheduled Board and committee meetings in order to share ideas and perspectives, build relationships, and gain a deeper understanding of the Company’s business. Corporate Governance 49 Annual Board and Committee Self-Evaluations Our Corporate Governance Guidelines and each of our committee charters require the Board and each committee to conduct an annual self-evaluation to determine whether the Board and its committees are functioning effectively. The following are some of the enhancements made to the self-evaluation process in 2022: • Evaluation Survey: The Governance Committee reviews and approves evaluation survey forms for each committee and the Board. These surveys are completed by each Board and committee member. • The evaluations ask for feedback on the leadership of the Board and committee, the content of the meetings, the role and structure of the committees, interaction with management, and each individual's performance. The evaluations also survey the Board members on the topics they deemed most important to discuss. • One-on-one Director Discussions: The Chair of the Governance Committee conducts individual meetings with each director to obtain candid feedback. • • Executive Session: Each committee and the Board discusses the results of the evaluations during executive session following the end of the fiscal year. The Chair of the Governance Committee shares the feedback with the Board to focus on areas in which the Board believes that it could improve. Implementation: Areas for improvement are communicated to the Board, management and the committees and action plans are developed and implemented. Board Oversight of Risk Management Strategic Oversight Our Board oversees and provides advice and guidance to senior management on the formulation and implementation of the Company's strategic plans, including the development of growth strategies by our senior management team. • This occurs year-round through presentations and discussions covering the competitive landscape, strategy, business planning and growth initiatives, both during and outside Board and committee meetings. The Board annually holds a Board retreat focused on the Company's long-term strategy. Our Board’s focus on overseeing risk management enhances our directors’ ability to provide insight and feedback to senior management on its development and implementation of the Company's long-term strategic plan. Our Chairman helps facilitate our Board’s oversight of strategy, including through discussions with independent directors during executive sessions, as needed. • • • Throughout 2022, our Board engaged on an ongoing basis with our CEO and CFO, as well as other key members of senior management to develop a growth-focused long-term strategy. The Company announced our long-term financial targets at our Investor Day in December 2022. • This took various forms, ranging from high-level discussions regarding strategic direction, reviews of existing and new business initiatives and progress on the execution of our value creation strategy as well as organic and inorganic growth opportunities. • The Board provided oversight on the execution of several key milestones in our Value Creation Plan including (1) a reduction of our real estate footprint following a strategic review of our real estate portfolio, representing an approximate 70% decrease in domestic leased space, which is expected to result in annual expense savings of more than $200 million, (2) signing a multi-year contract with Express Scripts, Inc. to provide our pharmacy benefit services commencing in 2024, and expected to drive significant value in 2024 and beyond, (3) completing the divestitures of PANTHERx Rare (PANTHERx), our Spanish and Central European businesses, and Magellan Rx, (4) completing $3.0 billion of common stock repurchases, $318 million of senior note repurchases, repaying our $180 million construction loan, and repaying over $100 million in revolver and term loan borrowings. • Discussions are focused on the quality and diversity of our people as well as alignment with our goal of long-term value creation for our stockholders and underscored by considerations such as risk management, culture and reputation. 50 Centene Corporation Our Board will continue to receive regular updates from, and provide advice to, management as they execute on the Company's strategy. Risk Oversight The Board has overall responsibility for the oversight of enterprise-wide risk management at Centene, while management is responsible for day-to-day risk management. The Board implements its risk oversight function both as a whole and through its committees. Each Board committee oversees risks associated with its respective principal areas of focus and then reports to the Board. These areas of focus include competitive, economic, operational, financial (including accounting, credit, liquidity and tax), legal, regulatory, compliance, political, strategic and reputational risks. The oversight responsibility of the Board and its committees is assisted by management reporting processes designed to provide visibility to the Board of the identification, assessment, prioritization and management of critical risks and management’s risk mitigation strategies. The Company’s process for the evaluation of risk is based on a blend of principles associated with the Committee of Sponsoring Organizations of the Treadway Commission (COSO) enterprise risk management framework, Enterprise Risk Management – Integrating with Strategy and Performance and ISO 31000: 2018 Risk Management. The primary goals of the enterprise risk management program are to enhance management’s ability to identify and assess the Company’s current risk status, gain insights on emerging risks, improve management’s strategic and operational decision-making ability and provide clear and timely communication of cross-functional risks to management and the Board. The enterprise risk management process is facilitated by the Company’s Internal Audit department. An enterprise risk management committee comprised of senior leaders within the Company meets at least four times per year to discuss the most significant known and emerging risks to the Company identified by the Company’s enterprise risk management process and the steps management has taken to identify, monitor, assess, and control or avoid such exposures. The enterprise risk management committee also reviews performance measures against the company's risk appetite and tolerance and provides recommendation(s) of corrective action, where appropriate. The enterprise risk management process is an active process and is continually enhanced and updated. The Company’s Risk department provides an enterprise risk management report to the full Board at least four times per year. Each Board committee reports to the Board any significant issues relating to their relevant risk areas. The principal areas of focus for enterprise risk management of the Board and each of its committees are summarized below. Each committee may meet in executive session with key management personnel and representatives of outside advisors as the committee members deem appropriate. Corporate Governance 51 Primary Areas of Risk Oversight • Strategic, financial and execution risks and exposures associated with the annual operating plan and long-term strategic plan • Major litigation and regulatory exposures, information security and other current matters that may present material risk to the Company’s operations, plans, prospects or reputation; and material acquisitions and divestitures Full Board Audit and Compliance Committee Compensation and Talent Committee Governance Committee Value Creation Committee • • • Risks and exposures associated with financial matters and regulatory requirements, including financial reporting, accounting, disclosure and compliance, internal control over financial reporting, financial policies, capital structure investment guidelines, liquidity matters and the Company’s regulatory compliance programs Legal and compliance risks Risks associated with information technology, including cybersecurity, privacy, disaster recovery and critical infrastructure assets Cybersecurity • Risks and exposures associated with leadership assessment and executive and non-executive compensation programs and arrangements, including incentive plans • • • Risks and exposures associated with quality and member experience initiatives Quality and effectiveness of the execution of the Company’s information technology initiatives and programs Risks associated with the execution of the Company’s long-term value creation (including margin expansion), growth and strategic initiatives and plans • • • • • Risks and exposures relating to the Company’s programs and policies relating to compliance with SEC governance requirements, NYSE listing requirements and similar legal requirements Corporate governance and director independence Director and chief executive officer succession planning Risks associated with environmental and social responsibility, social determinants of health and healthcare reform related risks and opportunities Risks associated with political and regulatory changes The Value Creation Committee is responsible for the quality and effectiveness of the Company's information technology, including cybersecurity programs, and the Audit and Compliance Committee manages the risks related to cybersecurity. The Audit and Compliance Committee receives updates on the Company's cybersecurity incident response plan and disaster recovery. Succession Planning As reflected in our Corporate Governance Guidelines, the Board's primary responsibilities include planning for CEO succession and monitoring and advising on succession planning for other executive officers. The Board's goal is to have a long-term and continuous program for effective senior leadership development and succession. The Board also has contingency plans in place for emergencies such as departure, death, or disability of the Chairman of the Board, the CEO or other executive officers.   52 Centene Corporation This involves extensive planning and oversight, including: • The entire Board works with the Governance Committee to evaluate potential successors to the CEO. • • • • • The CEO regularly evaluates and recommends potential successors for her role as well as other senior management roles, and recommends development plans for such individuals to the Governance Committee. The CEO discusses with the Compensation Committee individuals with high potential for succession as compensation decisions are being made. High-potential executives are regularly challenged with additional responsibilities to expose them to our diverse operations, as we strive to develop well-rounded and experienced senior leaders. Potential successors attend Board and Committee meetings and interact frequently with the Board in informal settings, so directors can get to know and evaluate them. The Governance Committee formally reports to the full Board at least annually on succession planning, and the Board discusses succession planning regularly at scheduled meetings, including in executive sessions, as appropriate. Sarah London's appointment as CEO of the Company in March 2022 and James Dallas as Chairman of the Board in April 2022, was the culmination of a nine-month long succession planning process. In July 2021, our longstanding CEO, Michael Neidorff informally communicated to the Board that he may decide for personal reasons to step down before the end of his contract, after which the Board and Mr. Neidorff established a succession planning initiative to ensure a full continuity plan. Sarah London was appointed Vice Chairman of the Board in September 2021. James Dallas was appointed as the Lead Independent Director in January 2022. In February 2022, the Board of Directors approved a request from Michael Neidorff for a paid medical leave of absence from his roles as Chief Executive Officer, Chairman, and a director of the Company. The Board also (i) appointed James Dallas as the Acting Chairman of the Board and (ii) appointed an expanded Office of the Chairman, consisting of Sarah London, Vice Chairman of the Board; Brent Layton, the Company’s President and Chief Operating Officer; Drew Asher, the Company’s Chief Financial Officer; and Shannon Bagley, the Company’s Chief Administrative Officer, to oversee the day-to-day management of the Company and discharge the duties of the Chief Executive Officer on an interim basis. During this time, the Board conducted an internal and external search process to determine a permanent CEO, which concluded as Sarah London was appointed as CEO in March 2022. In addition, Ken Fasola was appointed as President in December 2022, and James Murray as Executive Vice President, Chief Operating Officer, as Brent Layton, the Company's then-President and Chief Operating Officer announced his intention to retire in late 2023. Management also focuses on succession planning at all people leader positions throughout the organization. During the Company's annual performance review process, each leader identifies high performing talent who are potential successors for their roles, as well as any areas where we might have gaps. Government Relations and Related Activities We believe that engagement with governmental officials and agencies plays a key role in influencing sound public healthcare policy as well as shaping regulations and legislation that govern our business now and into the future. In keeping with our purpose to transform the health of the community, one person at a time, and in an effort to be transparent about the principles that govern our participation in the political process, in 2020, we began posting disclosures concerning our political and lobbying activities on our corporate website. Our Political Activity Reports are available at www.centene.com. Our Governance committee oversees policies and practices regarding political and charitable activities, including any contributions therewith. Corporate Governance 53 Environmental, Social, Health, and Governance and Corporate Sustainability With nearly four decades of experience operating government-sponsored programs, we understand the importance of how environmental and social factors impact the long-term health and well-being of people. We refer to four pillars within our sustainability strategy and framework: environmental, social, health, and governance (ESHG). We separately highlight Health (H) as a pillar because improving the health of our members is our purpose. Our trusted relationships with stakeholders are built on transparency and aligned incentives to do what is best for our members and their health and deliver better health outcomes at lower costs. We harness the power of data to help us identify social determinants of health (SDoH) and enable us to reach out and provide support to our members. We are leading this effort with a health equity lens applied to managed care; creating a more robust healthcare experience for our members, addressing disparities, and improving trust. Ultimately, helping our members achieve improved health lowers our costs and theirs, and delivers value to our government partners and other stakeholders. Our focus on issues that fall within the Social (S) pillar of ESHG, like employee health and well-being, employee development, and Diversity, Equity, and Inclusion (DEI), helps us differentiate ourselves in the marketplace and produce a more resilient and innovative workforce. We cement our social and community impact through partnerships, local investment, and volunteerism that mutually support our goals and strategy. For example, by focusing giving efforts on social services and education, and directing care management towards SDoH needs identification, we aim to improve the socioeconomics of our nation’s most vulnerable children. Our community investments are directed towards enhancing the well-being of our members and their communities, which is foundational to healthier lives. By leveraging our scale and expertise, while at the same time using a hyper-local approach to health insurance, we deliver on quality healthcare for our members, and financial predictability and reduced administrative burden for our government partners. We address Environmental (E) topics by reducing our operational resource usage and identifying how we can help members and our communities with climate resiliency. Our success is dependent on a culture of accountability and a commitment to strong ethics, compliance, and data privacy and security, which are essential to strong corporate governance and the (G) pillar. The following paragraphs provide a brief overview of the context of ESHG at Centene and highlight examples of how we deliver value through our mission-driven strategy. Health The health pillar is core to our strategic vision and execution. As we get the basics right and honor our commitments to healthcare quality, we will improve quality care delivery. As we look to lead the conversation on health equity and drivers of health, we will strengthen the healthcare system and in turn, outcomes for our members. And as we design solutions for the most complex members, we will deliver measurable value to the most vulnerable populations. Our efforts are focused on meeting local needs in tailored ways. Key principles of this work include: • Highly local system engagement – we partner across community, member, and provider stakeholders to drive system- level support. • • • Data driven – we use evidence-based approaches and both qualitative and quantitative insights to identify, address, and improve outcomes. Population health – we create tailored, whole-health interventions to meet needs unique to each population. Health equity – we view interventions and outcomes through an equity lens, acknowledging disparities and working toward equity across factors such as race, geography, and socioeconomic status. 54 Centene Corporation Healthcare Affordability Amid an evolving healthcare landscape, we are committed to supporting policies that promote healthcare access and reduce the cost of receiving care. Leveraging our many years of experience in government-sponsored healthcare, we can deliver cost effective services for the benefit of both our members and government partners. We seek to establish and strengthen durable, trusted partnerships, enabling us to offer a variety of healthcare coverage options to meet the different needs of our members and those seeking affordable care. • Optimizing Site of Service: Through managed care of government-sponsored programs, we drive greater affordability for the health system by helping our members access high-quality care in lower-cost settings. We provide a comprehensive set of education and outreach programs to inform, assist and incentivize members to access high-quality, appropriate healthcare services in an efficient manner. For example, our Emergency Department Diversion program is designed to collaboratively work with hospitals to reduce avoidable emergency department visits through patient education and alternative urgent care settings. We also make available, as an alternative to high-cost settings, the use of telehealth visits either through our network of qualified providers or contracted national vendors to provide expanded capacity. • Value-Based Care: Value-based models of care are a foundation of the interactions we have with our network providers. Centene is working with providers across our product offerings to implement value-based programs, enabling providers to share in a percentage of savings through improving the overall quality of care. Beyond traditional provider incentives, Centene embeds SDoH and health equity as core components of our value-based approach. We focus on incentivizing primary care providers to further enhance care for our members by providing information and wrap around support, such as claims, member experience, and discharge information via detailed reporting packages. The programs empower physicians to provide the best care to our members. As of December 31, 2022, 45% of our Medicare Advantage members, 41% of our Medicaid members, and 9% of our Marketplace members were served by providers in value-based contracts. Healthcare Access From its inception, Centene has understood the importance of SDoH on access to care. Centene sees our members often disproportionately impacted by SDoH barriers that lead to negative health outcomes. As the largest healthcare insurer of underserved and underinsured populations in the United States, we leverage our data to better understand our members and lead through innovation to address health equity and drivers of health. By cultivating multi-year partnerships, locally and nationally with community, provider, and civic and government organizations, we work to solve cross-sector problems our members face, sustainably and at scale. • Virtual Care: Centene recognizes that virtual care can not only improve continuity of care but can enhance and optimize our members’ physical and behavioral healthcare experience. Through national telehealth partnerships, we aim to deliver high-quality, patient-centered care in a way that works best for our members–easily accessible and when they need it. In 2022, Centene partnered with various telehealth vendors to provide over 14 million virtual visits to Centene’s members. We are planning to further expand our virtual care network with a focus on holistic delivery of care, which includes adding specialty providers such as pediatric therapy, reproductive health, and substance abuse treatment. • Centene’s care management teams also utilize virtual tools to enhance the member experience. Digital Care Management is an interactive platform that offers simple and real-time chat interaction to increase member engagement, promotes active involvement in the management of a member's own health, and provides an alternative care management approach for members who prefer digital outreach. Healthcare Quality and Member Well-Being The delivery of high-quality health services to at-risk populations serves as a living expression of our purpose – transforming the health of communities, one person at a time. While Centene leads in Medicaid and Marketplace, Medicare Advantage (MA), in particular, represents a critical area of the company’s future growth. Quality is a cornerstone to the success of Centene and a large focus across the organization, especially relating to our Medicare Stars ratings. Members deserve nothing less than high-quality healthcare. Corporate Governance 55 The Medicare Advantage Five-Star Quality Rating System, developed by the Centers for Medicare & Medicaid Services (CMS), aims to elevate accountability of health plans and serves as a roadmap to shape Centene’s MA program in a way that makes it easier for clinicians to work with us and assists them in helping our members lead their healthiest lives. In recent years, CMS has made several significant revisions to the Stars rating process, placing a greater emphasis on member experience and day-to-day health plan operations. As we enter the next Stars rating cycle, Centene is focused on improving its Stars ratings, including the measures relating to member experience and day-to-day health plan functions. Ensuring we continue advancing our mission of achieving better health outcomes for our members has led to recent investments in key initiatives involving people, processes, technology, and partner management. We have increased staffing in critical customer-facing areas, improved processes within operational business units to drive more efficiency and effectiveness, and developed advanced analytics to orchestrate pivotal member engagement, and increase clinical outcomes and satisfaction in the care being delivered to our members. We are using these tools to better support and strengthen partnerships with providers to improve access to care and the quality of care members receive. • 62 Centene legal entities hold one or more National Committee for Quality Assurance accreditations • 3 Centene specialty companies hold one or more URAC accreditation Social Creating positive social impact is the central theme of the topics we focus on within the social pillar. Diversity is a strategic imperative and is one way in which we embody "One CenTeam". Having both a diverse workforce and developing diverse, trusted partnerships enable us to better understand the unique needs of the communities we serve. Other focus areas within the social pillar highlight how we make lasting impacts through partnerships, investments, and employee volunteerism. Diversity, Equity & Inclusion Diversity is a strategic imperative. The framework of Centene’s Diversity, Equity & Inclusion (DEI) strategy guides our efforts and holds us accountable for measurable progress. Data and analytics are key, and we continuously adapt how we measure and review our data to find opportunities for improvement. In partnership with our five Employee Inclusion Groups, our Executive DEI Council, leaders, and employees across Centene, we are committed to advancing the implementation of DEI principles into all aspects of our business, empowering and aligning our people as one team. The Company is committed to a workforce that represents diversity, equity, and inclusion as shown below: OUR COMMITMENT TO DIVERSITY, EQUITY, AND INCLUSION 77% 48% 3% 11% 66% 36% 18% Women People of Color Veterans Identify as Having a Disability Supervisor+ Positions Held by Women Supervisor+ Positions Held by People of Color Employee Inclusion Group Participation Information as of December 31, 2022.

In 2022, the DEI Office and Employee Inclusion Groups hosted a total of over 250 programs with over 25,000 employees attending across all programs. Additionally, Centene has established a network of business unit DEI Councils and local Employee Inclusion Group chapters across the country, allowing the organization to further deliver nuanced and impactful initiatives to employees. 56 Centene Corporation • Centene’s Human Resources Compliance team, in partnership with the DEI Office and Centene University, delivers Inclusive and Responsible Workplace learning to ensure employees are exposed to best practices and policies to sustain an equitable workplace. • • Employee Inclusion Groups encompass multicultural, veterans and military, LGBTQ+, and networks for women and people with disabilities. As a demonstration of our hyper-local approach, our local boards are comprised of members of our communities. As of December 31, 2022, the 198 directors on the external boards of our regulated health plans reflected diversity as follows: 65% 39% 23% 7% 6% 5% 3% 1% Caucasian Female African American Veteran Hispanic Asian/ Indian Disability Native American Employee Focus EMPLOYEE HEALTH AND WELL-BEING Our mission to transform the health of our communities includes enabling our employees to pursue their personal and career development, engage in healthy lifestyles, and actively contribute to their families and communities. As a reflection of this, our Social pillar includes employee-focused topics such as Employee Health and Well-being, Employee Partnership and Development, and Community Engagement. It is through these topics that we frame strategic discussions and efforts around employee wellness. These include lifestyle improvements through on-campus facility designs or reduced need for in- office work, and benefits that support healthy living, caregiver support, financial health, work-life balance, professional growth, and connecting with our communities. For more information regarding our employee health and other benefits, please visit our prospective employee website: https://jobs.centene.com/us/en/benefits. EMPLOYEE PARTNERSHIP AND DEVELOPMENT At Centene, we strive to empower each employee to lead from where they are. For this reason, we regularly offer a variety of development opportunities through enterprise-wide training, specially curated learnings, and targeted leadership programs. These offerings inspire a culture of learning, curiosity and collaboration. Through our employee intranet site CNET, our employees stay informed, access resources, and engage in opportunities to serve communities. Through Centene University, we support employees in achieving their career and learning goals by offering over 10,000 courses on topics such as leadership, operations, technology, mentoring, career development, as well as our DEI and ESHG frameworks. Our employees are provided with opportunities to engage with others throughout the company by becoming mentors, joining virtual communities, and taking leadership positions within employee project groups and committees. Our corporate leaders directly engage employees through our Coffee with Leadership Series, DEI Employee Inclusion Groups, town halls, and company wide newsletters. We also host innovative crowdsourcing competitions, which result in employee ideas helping our organization better serve our members and communities. EMPLOYEE ENGAGEMENT • Employee Engagement Index: Centene’s 2022 overall engagement score exceeded the Fortune 100 75th top quartile benchmark, at 88% favorability. • • People Leader Index: Centene's 2022 measure of individual people leader effectiveness (encouraging teamwork/ collaboration, providing regular feedback and supporting career development) was 86%, 2 points higher than the Fortune 100 75th top quartile benchmark.

Community Outreach, Investment and Engagement Centene is uniquely focused on underserved populations, investing in local institutions and organizations that address the needs of their communities through initiatives that demonstrate inclusion, consider the whole person, and enable Corporate Governance 57 community development. The Centene Charitable Foundation is an essential part of how we pursue that purpose, as we prioritize partnership and giving initiatives that take a holistic approach to disrupting barriers to health and provide measurable impact to the communities where we live, work, and serve. Through strategic partnerships with local organizations and a commitment to our company’s overarching purpose, The Centene Charitable Foundation aims to remove barriers to health for the underserved and provide long-term results that truly transform our communities in the following areas: • Healthcare Access (including Social Determinants of Health) • • Education Social Services Centene’s community outreach, investment, and employee engagement efforts reflect a diverse geographic footprint that benefits economically challenged communities and engages employees at all levels within the organization. Environmental Our approach to environmental topics at Centene is one way in which we lead through innovation. We are mindful about environmental stewardship and that where and how we work impacts the environment. Our health plans maintain a local presence in our communities enabling us to be proactive where possible and quickly help our members navigate and manage weather-driven events. Analysis of our data helps us identify health issues that may be the result of environmental impacts. Environment and Health Scientific research continues to show a causal relationship between environmental factors and negative impacts on health. Rising temperatures are linked to increases in mental health issues as well as cardiovascular failure. More extreme weather events are linked to increases in the prevalence of asthma and vector-borne diseases. While climate change impacts everyone, its results are often disproportionately felt by the vulnerable populations we serve. As an insurer of millions of members’ health, we strive to understand the impacts of environmental factors, analyze our data, and promote and advance innovation to improve health drivers for our members and our communities. Our corporate, local health plan, and business unit leadership is engaged in closely monitoring environmental and climate-related risks and their potential impact on our members. To further advance our work around climate-related risks, the Climate Change Task Force was formed and meets as needed to identify climate-related issues, outline climate change scenarios, assess transition and physical factors, and determine mitigation actions. Environmental Disclosures As part of our commitment to being good stewards of the environment, we work to understand, quantify, and reduce our impact on the natural world. As part of our Value Creation Plan, we have significantly reduced our need for physical office space and daily employee commuting, and will continue to cultivate an ecosystem of strategic partners that enables innovation to reduce our physical impact on the environment. Through an initial assessment performed in 2021, we recognize climate change can pose both risk and opportunity for our business. We complete the following to raise understanding about climate change, better manage risk, address opportunities, and improve disclosures around environmental topics: • • • Issue annual reporting aligned with the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD) Evaluate potential enterprise risks associated with climate change Disclose our baseline and recent years’ scope 1, scope 2, and scope 3 greenhouse gas emissions through CDP, a global non-profit that runs the world's environmental disclosure system 58 Centene Corporation Evaluation of Enterprise Risks Associated with Climate Change Centene’s Enterprise Risk Management (ERM) function coordinates and applies an integrated approach whereby risks are identified and assessed across Centene and its business units. The ERM team reports risk information on a quarterly basis to the Enterprise Risk Committee, a cross-functional group of senior leaders chaired by the Chief Ethics & Compliance Officer. The ERM and ESHG functions are led by the same individuals and work in close collaboration, sharing people and other resources. The ESHG function coordinates and facilitates all internal and external ESHG reporting and works closely with ERM to incorporate climate-related risks within the corporate risk register for monitoring. For more information regarding our assessment of climate risks and opportunities, please see our TCFD reporting. Governance Sound corporate governance, a strong culture of compliance and unwavering ethics are foundational to our ESHG strategy, enabling us to honor our commitments and make it easier to work with us. Governance and accountability for corporate sustainability begin at the top of the organization. Through its Governance Committee, the Centene Board of Directors provides strategic oversight into how the company addresses matters of ESHG importance. The Audit and Compliance Committee oversees the procedures and controls related to ESG financial reporting disclosures. Over the past several years, we have significantly improved our ESHG governance and reporting to be consistent with leading businesses, as highlighted in the 2022 Stockholder Engagement and Response section of this proxy statement. We leverage external reporting frameworks to guide disclosure of relevant data and align with best practices for reporting. Additionally, we engage our employees in enterprise-wide sustainability and social activities and communicate key information via our intranet website. To improve access to and awareness of our ESHG initiatives and key reports and disclosures, we make this information available within the Corporate Sustainability section of our external corporate website and via an ESG page on our investor-focused website. We support worldwide efforts as expressed through commitments with the UN Global Compact, Women’s Empowerment Principles, and the Ethical Principles in Health Care. Each provides us opportunities to contribute towards a more just and equitable healthcare landscape.   Corporate Governance 59 ESHG information and related disclosures are available on our external website, including the following: Our ESHG Report to the Community details the key partnerships, initiatives, and programs that exemplify our commitment to advancing environmental resilience, serving our communities, powering better health, and living our values.

Our information security and privacy programs are built to support that goal and help us to design and deliver seamless member and provider experiences using modernized systems and processes. Our Enterprise Data Privacy Program describes the measures we take to protect information and how individuals may exercise their data privacy rights under applicable regulations. Federal, state, and international regulations, in addition to contract obligations, create a highly regulated environment in which our business operates. To effectively manage, we maintain comprehensive information security and privacy programs that allow for full compliance with these regulations. These programs are assessed annually in compliance with the HIPAA Privacy and Security Rules, HITECH Act, and the GDPR. Our information security program conforms with ISO 27001and is certified by an accredited organization. We provide annual information security and privacy training and specialized role-based training to our employees and communicate security awareness items in multiple formats including awareness of the importance of timely notification of potential security and privacy issues. We also conduct a “Compliance and Security Awareness” week to build and support our culture of compliance and reduce risk across the enterprise. HIPAA privacy breaches, as required by law, are reported by Centene to the U.S. Department of Health and Human Services, Office for Civil Rights (OCR). Our reports can be obtained through the OCR Portal at: https://ocrportal.hhs.gov/ocr/breach. In addition to the information security and privacy programs described above, we annually purchase a security and privacy risk insurance policy that could offset some of the costs associated with an information security breach. Please refer to our ESHG Report to the Community for further information regarding data privacy and security. Stockholder Engagement We believe that engaging with stockholders and other stakeholders is fundamental to the Company’s success and our commitment to good governance. We seek to proactively listen to, understand and consider the opinions of our stockholders to stay aligned with stockholder priorities. Over the past several years, we have significantly expanded our governance-focused engagement program to better understand the issues that are important to our stockholders and incorporate feedback into the Board’s decision-making process. Members of our management team, including our CEO, CFO, General Counsel and our Senior Vice President of Investor Relations and Board regularly meet with stockholders to gather their perspectives on key topics including our performance and strategy, corporate governance, management succession planning, executive compensation, human capital management and corporate responsibility. Beyond our governance-focused engagement, our investor relations team and members of our senior management team regularly communicate with investors in connection with quarterly earnings calls, investor and industry conferences, analyst meetings and individual discussions with stockholders. As described in the diagram below, we report stockholder feedback regularly to our Board, which in turn uses this feedback to evaluate any changes to the Company’s practices year-round. Corporate Governance 61 September-November (Fall) • Conduct meetings with our largest stockholders, to discuss corporate governance, corporate responsibility and executive compensation matters, and solicit feedback • Share the feedback with the Board for discussion and consideration May-August (Summer) • Review annual meeting results, ongoing stockholder feedback and determine any next steps, including corporate governance and compensation trends to help develop stockholder engagement priorities December-February (Winter) • Incorporate feedback from stockholder meetings into annual meeting planning, including potential changes to corporate governance practices, the executive compensation program and corporate responsibility • Review stockholder proposals and determine next steps March-April (Spring) • Conduct Investor meetings in advance of the annual meeting to answer questions and obtain stockholder feedback on proxy matters In response to the 66% of our stockholders voting against our 2022 say-on pay, the Board undertook an extensive outreach effort to understand our stockholders’ concerns and make responsive changes to our executive compensation program which are summarized below.

Compensation Committee Interlocks and Insider Participation During all or part of 2022, Orlando Ayala, Jessica Blume, Christopher Coughlin, Wayne DeVeydt, Robert Ditmore, Monte Ford, Richard Gephardt, Lori Robinson, Theodore Samuels and William Trubeck served as members of the Compensation and Talent Committee. Robert Ditmore served as chairman until January 5, 2022, at which time Christopher Coughlin was appointed chairman and continues to serve as chairman. None of these directors served as an officer or employee of the Company or any of its subsidiaries before or at the time he or she served on the Compensation and Talent Committee or had any relationship during 2022 that would require disclosure under Item 404 of SEC Regulation S-K. During 2022, none of our executive officers served on the Compensation and Talent Committee (or its equivalent) or board of directors of another entity, one of whose executive officers served on our Board or Compensation and Talent Committee. Related Party Transactions We have a written policy for reviewing transactions between us and our executive officers, directors and certain of their immediate family members and other related persons, including those required to be reported under Item 404 of Regulation S-K. Under this policy, the Governance Committee must approve any transaction in which we participate that involves more than $120,000 and in which a related person has a direct or indirect material interest. Pursuant to our policy, we enter into a transaction with such related persons only if the transaction is on terms deemed comparable to those that could be obtained in arm’s length dealings with an unrelated third party and is otherwise fair to us. Effective January 23, 2021, the Company entered into a consulting agreement with Kenneth Burdick, our former Executive Vice President, Markets and Products and former Chief Executive Officer of WellCare. Under the terms of the agreement, Mr. Burdick provided strategy advice and counsel, including, but not limited to WellCare legacy operations, integration matters, and ongoing guidance to his successor. In exchange for these services, the Company paid Mr. Burdick $350,000 per quarter in cash. The agreement expired in accordance with its terms on January 22, 2022. In addition, Mr. Burdick became Chairman and CEO of LifeStance Health Group, Inc. in September 2022. Centene paid LifeStance for behavioral health services provided by LifeStance to the Company's health plans in accordance with contracts entered into between the companies prior to Mr. Burdick's employment with LifeStance. These contracts were obtained on arms' length dealings prior to the time that Mr. Burdick became affiliated with LifeStance. In 2022, one of our executive officers had a related party employed by the Company who earned total compensation above $120,000. The employee's compensation and benefits was consistent with total compensation and benefits provided to other employees of the same level with similar responsibilities. 64 Centene Corporation Compensation of Directors For 2022, non-employee directors received an annual cash retainer of $100,000. If the director elected to receive 100% of the retainer in Company stock and, for directors who served prior to 2022, defer settlement of the stock until termination of Board service, the retainer was increased to $125,000. In addition, the Chairman of the Audit Committee received an annual retainer of $30,000, the Chairman of the Compensation Committee and Nominating and Governance Committee each received an annual retainer of $20,000, and the Chairman of the Government and Regulatory Affairs Committee, Technology Committee, and Environmental and Social Responsibility Committee, and Compliance Committee each received an annual retainer of $15,000. All fees were pro-rated, as applicable throughout 2022 based on time served on the respective committee. Directors can elect to receive any of these retainers in deferred stock under the Non-Employee Directors Deferred Stock Compensation Plan. Expense recognized in conjunction with the deferred stock election is included in the “Stock Awards” column in the Director Compensation Table below. In August 2022, the Company restructured the Board Committees resulting in an updated fee structure set forth below.

For 2022, the grant was valued at $200,000 based on the first quarter average stock price and resulted in a grant of 2,323 restricted shares of our common stock in April 2022. The restricted stock units vest on the earlier of April 26, 2023 or the 2023 Annual Meeting of Stockholders, subject to satisfying Board of Director meeting attendance conditions. In addition, each new non-employee director was granted an option under our 2012 Stock Incentive Plan to purchase 10,000 shares of our common stock, vesting in three equal annual installments commencing on the first anniversary of the grant date. Variable compensation for meetings in excess of six per year was eliminated in 2022. Directors are reimbursed for all reasonable expenses incurred in connection with their service. Directors who are also our employees receive no additional compensation for serving on our Board of Directors. In February 2023, the Compensation Committee made further changes to the director compensation program: • The Chairman of the Board is also eligible to receive the annual retainer for the Non-Employee Directors, in addition to the $150,000 stock retainer and $50,000 cash retainer for the Chairman. • • The initial grant of 10,000 options provided upon first election to the Board has been eliminated.

Pursuant to Section 14A of the Securities Exchange Act of 1934, as amended (the Exchange Act), we are again holding an advisory vote on the Company’s executive compensation, as described in this Proxy Statement (commonly referred to as “say-on-pay”). In accordance with the results of the vote we conducted at the 2017 Annual Meeting on the frequency of say- on-pay votes, we present a say-on-pay vote every year. The Board of Directors strongly endorses the Company’s executive compensation program and recommends that stockholders vote in favor of the following resolution: RESOLVED, that the stockholders approve the compensation of those NEOs listed in the Summary Compensation Table of this proxy statement, as disclosed pursuant to the compensation disclosure rules of the SEC, including the Compensation Discussion and Analysis and the tabular and narrative disclosure included herein under “Executive Compensation.” Because the vote is advisory, it will not be binding upon the Board of Directors or the Compensation Committee and neither the Board of Directors nor the Compensation and Talent Committee will be required to take any action as a result of the outcome of the vote on this proposal. The Compensation and Talent Committee strongly considers the views of the Company’s stockholders when making compensation decisions. Additionally, the Compensation and Talent Committee monitors the results of the annual advisory “say-on-pay” proposal and incorporates such results as one of many factors considered in connection with the discharge of its responsibilities. The Board recommends a vote “FOR” the approval of the compensation of the NEOs. 70 Centene Corporation Letter from Chairman of Compensation and Talent Committee Dear Stockholder: 2022 was a year of extraordinary change for Centene Corporation. I joined the Board of Directors in January 2022, and became chairman of the Compensation Committee, which was renamed the Compensation and Talent Committee in August 2022. In connection with that, we replaced our prior executive compensation consulting firm with Frederic W. Cook & Co., Inc. I, along with other members of the Board of Directors, have met with stockholders representing 41% of the Company's outstanding shares and the leading proxy advisory firms. As a result of the feedback we received from stockholders and the proxy advisory firms, we have made some important changes to our compensation program as summarized in this proxy statement, and outlined below. 2022 Highlights • Our new CEO's compensation was set slightly below the median in April 2022. • • • We adopted a cash severance policy to limit cash severance to 2.99 times annual salary and bonus. We limited our former CEO's death benefits to those of his pre-existing employment agreement. We welcomed General Robinson, Mr. Ford and Mr. Samuels as new members of the committee during 2022, decreasing the average tenure of our committee members to four years from 11 years compared to December 2021. After the 2023 Annual Meeting, the average tenure of our committee members is expected to further decrease to less than two years. 2023 Highlights • We have provided additional disclosure of our performance metrics and targets for the Business Unit and Quality components, which, like the Adjusted Diluted EPS component, are measurable and financially and operationally driven. We increased the Adjusted Diluted EPS component of our 2023 annual cash incentive plan from 50% to 65%. • • • Beginning with our 2023-2025 long-term incentives, we have moved away from the use of performance-based stock options and the cash long-term incentive plan (LTIP) to simplify overall program design, better align with leading market and peer practices, and further enhance the alignment between management incentives and stockholder value creation. Beginning with our 2023-2025 performance-based RSUs, we have moved away from the use of Adjusted Diluted EPS in favor of adjusted pre-tax earnings growth to avoid the use of duplicative measures in both the short- and long-term incentive programs while maintaining a robust focus on long-term profitability and stockholder value creation for management incentives. Previously, the performance-based RSUs had no total shareholder return (TSR) metric. Beginning with our 2023-2025 performance-based RSUs, the plan metrics include a 33% weighting on a target relative TSR performance above the median. • We revised certain employment agreements to change provisions that could be perceived as problematic pay practices. Please see the Compensation Discussion and Analysis below for further details of our compensation changes. Sincerely, Christopher J. Coughlin Chair Proposal 2 – Advisory Resolution to Approve Executive Compensation 71 Compensation Discussion and Analysis This CD&A describes the principles, objectives, and compensation policies and arrangements of our executive compensation program which is generally applicable to each of our senior officers. This CD&A focuses primarily on our Chief Executive Officer and the other executive officers whose 2022 compensation is included in the Summary Compensation Table, whom we collectively refer to in this proxy as our Named Executive Officers (NEOs). Name Sarah M. London Andrew L. Asher Kenneth J. Fasola James E. Murray Position Chief Executive Officer Executive Vice President, Chief Financial Officer President Executive Vice President, Chief Operating Officer Christopher A. Koster Executive Vice President, Secretary and General Counsel In addition, as required by SEC rules, we also include as NEOs our former Chairman and Chief Executive Officer, Michael F. Neidorff, as well as Brent D. Layton, Senior Advisor to the Chief Executive Officer, and David P. Thomas, Chief Executive Officer of Markets and Medicaid. Mr. Layton and Mr. Thomas are included as they otherwise would have been NEOs except for the fact that they were not serving as an executive officer at the end of 2022. Mr. Layton and Mr. Thomas remain with the Company in non-executive officer roles. Executive Summary As our new Chairman of the Compensation Committee stated in his letter to stockholders, 2022 was a year of extraordinary change for Centene Corporation. In March 2022, Centene executed on its succession plan by appointing Sarah London, Vice-Chairman, to the role of Chief Executive Officer. In August 2022, and as part of Centene’s broader plan to enhance governance and refresh board committees, Christopher Coughlin was named Chair of the Compensation Committee. 2022 also was the year Centene embarked on a multi-year journey to ensure its compensation programs evolved to align better with market practices, incorporate the strong and clear feedback from our shareholders, drive strong performance, and create shareholder value. We also made a concerted effort to enhance our disclosures around the process and criteria used to make these important compensation decisions related to our NEOs. The following provides an overview of the evolution of our compensation programs and governance practices, which were informed by our stockholder outreach and “best practice” market trends: 72 Centene Corporation Category 2021 2022 2023 Annual Incentive Plan Metrics & Weighting Granted in Dec. 2020 Granted in Dec. 2021 Granted in Mar. 2023 Adjusted Diluted EPS 35% Adjusted Diluted EPS 50% Adjusted Diluted EPS 65% Business Unit & Individual Goals SG&A Expense Management 50% 15% Business Unit & Individual Goals Quality 40% 10% Business Unit & Individual Goals Quality 25% 10% • • • Reduced Individual weighting • Reduced Individual weighting Increased Adjusted Diluted EPS Weighting • Increased Adjusted Diluted EPS Weighting Added Quality Metric PSUs Adjusted Pre-Tax Margin 60% Adjusted Diluted EPS 70% Revenue Growth CAGR 40% Adjusted Net Earnings Margin 30% Stock Options Granted to CEO without a stock appreciation condition Cash LTIP Adjusted Pre-Tax Margin Granted in Dec. 2021 with a stock appreciation condition No Stock Options Granted in 2022 30% Adjusted Diluted EPS 35% Adjusted Pre-Tax Earnings Growth CAGR Adjusted Net Earnings Margin Relative TSR 34% 33% 33% Added rTSR with target > median Eliminated duplicative Adjusted Diluted EPS measure • • Eliminated Stock Options Revenue Growth CAGR 20% Adjusted Net Earnings Margin Relative TSR 50% Relative TSR 15% 50% Eliminated Cash LTIP Other • • New CEO compensation set slightly below the median New policy limits cash severance to 2.99x base + bonus Refer to Appendix A for reconciliations of non-GAAP measures throughout this proxy statement. In addition to these important changes around leadership, governance and compensation, we continue to move forward with our Value Creation Plan, which is focused on increased stockholder value through actions including cost reduction initiatives, gross margin expansion through bid discipline and cost management, portfolio optimization, and strategic capital allocation. Along with creating stockholder value, this plan encompasses a larger organizational mission to enhance our member and provider experience, improve outcomes for our members, and initiate new ways of doing business that make Centene a valued partner in all aspects of our operations. During 2022, we completed key milestones in our Value Creation Plan: Proposal 2 – Advisory Resolution to Approve Executive Compensation 73 >$200M Cost Savings By 70% decrease in domestic footprint $3B Common Stock Repurchases >$800M Debt Reduction Further, in 2022, Centene signed a multi-year contract with Express Scripts, Inc. to provide our pharmacy benefit services, commencing in 2024, and expected to drive significant value in 2024 and beyond and completed the divestitures of PANTHERx, our Spanish and Central European businesses, and Magellan Rx. During 2022, our stock price performance remained relatively flat at -0.5%, outperforming the S&P 500 index return of -19.4%. 2022 Performance Highlights The Company delivered solid financial performance in 2022 as outlined below.

Our directors, including Jessica Blume, Christopher Coughlin, Wayne DeVeydt and Theodore Samuels participated in a number of these engagements. We extended meeting invitations to 16 stockholders, representing approximately 56% of our outstanding shares, and ultimately met with 11 stockholders, representing approximately 41% of our outstanding shares. In addition, members of our management team and Board regularly meet with stockholders and proxy advisor firms to gather their perspectives on key topics including our performance and strategy, corporate governance, management succession planning, executive compensation, human capital management and corporate responsibility. Beyond our governance-focused engagement, our investor relations team and members of our senior management team regularly communicate with investors in connection with quarterly earnings calls, investor and industry conferences, analyst meetings and individual discussions with stockholders. In response to the result of our 2022 say-on-pay vote, and our subsequent stockholder outreach, we have made some important changes to our compensation program starting with the 2023 short-term annual incentive plan and our 2023-2025 long-term incentive plan as summarized below. Category What We Heard What We Changed Executive Compensation Align CEO compensation with peers Align NEO compensation with peers Annual Incentive Plan should have clearer performance targets Long-Term Incentive Compensation Program should have fewer components Long-Term Incentive Compensation Program should have targets different from Annual Incentive Plan Long-Term Incentive Plan should use relative Total Shareholder Return (TSR) as a performance metric Performance against targets should be disclosed more clearly Limit severance payments Review relationship with compensation consultant New CEO compensation set slightly below the median in April 2022 Offers for new hires made with the goal of being at the 50th percentile Increased Adjusted Diluted EPS to 50% of the performance criteria in 2022 and a further increase to 65% in 2023 Weighting of business unit and individual goals have been decreased to 40% in 2022 and 25% in 2023; business unit goals are measurable against key financial and operational priorities Quality metrics represent 10% of the performance criteria 2023-2025 Plan no longer includes performance-based stock options 2023-2025 Plan no longer includes Cash LTIP 2023-2025 Plan metrics are all different from the Annual Incentive Plan targets 2023-2025 Plan includes 33% of PSUs tied to relative TSR performance metric Performance against targets is described in the 2022 Executive Compensation Program section under Compensation Discussion and Analysis Limited Michael Neidorff’s death benefits to those required by his pre-existing employment agreement Adopted cash severance policy to limit cash severance to 2.99 times annual salary and bonus Appointed Frederic W. Cook & Co., Inc. (FW Cook) as new compensation consultant in 2022 Proposal 2 – Advisory Resolution to Approve Executive Compensation 75 Our Compensation Programs and Governance Practices Compensation Philosophy The following principles guide the Company’s compensation philosophy: • Pay for Performance - Our overall compensation philosophy is to pay for performance. Executive compensation is directly linked to performance and the achievement of both Company and individual goals. Superior performance and the achievement of goals results in higher compensation. • • • Create Long-term Stockholder Value - Both performance-based and service-based long-term incentive awards with meaningful retention requirements are used to encourage sustained stockholder value creation. Foster a Culture of Risk Management and Compliance - A portion of senior executive compensation is based on meeting financial, business, and quality goals that align with our corporate mission statement and promote a culture of compliance with rules, regulations and the Company’s vision and values. Attract and Retain Top Executive Talent - We offer competitive pay to attract, motivate, and retain industry executives with the skills and experience to drive superior long-term Company success. Executive Compensation Practices The Compensation Committee establishes the executive compensation philosophy and administers the executive compensation program and assists the Board of Directors in the development and oversight of all aspects of executive compensation. Presented in the table below are highlights of our compensation practices: What We Do    Pay for Performance    Stock Ownership Requirements A significant portion of our NEOs’ compensation is tied to performance with clearly articulated financial and performance goals.    Competitive Compensation Each component of the NEOs’ annual total direct compensation is generally targeted at the 50th percentile of peer group compensation. The Compensation Committee may consider differences from the median in certain cases.    Long-Term Incentive Awards Reward continuous performance on multiple metrics and vest at the end of a three-year period.    Formula Based Annual Incentive Plan Awards under the Annual Cash Incentive plan are formula based.  Tally Sheets Tally sheets and wealth accumulation analyses for each NEO are reviewed annually.  Annual Compensation Risk Assessment We regularly analyze risks related to our compensation program and we conduct broad risk assessments. We maintain rigorous stock ownership requirements for our directors, executives, and other members of senior management. Our CEO’s requirement is 5x annual base pay; other NEOs’ requirements are 2.5x annual base pay. Clawbacks We can recover performance-based cash and equity incentive compensation paid to executives in various circumstances. Independent Compensation Consultant The Compensation Committee retains an independent compensation consultant to advise the committee on executive compensation matters. Executive Severance Arrangements The Compensation Committee reviews severance policies annually and limits the usage of one-off arrangements.                   76 Centene Corporation What We Don’t Do     Excessive Risk-Taking in Our Compensation Programs The long-term incentive plans use multiple performance measures, capped payouts, and other features intended to minimize the incentive to take overly risky actions. No Tax Gross-ups There are no tax “gross-ups” for perquisites or excise tax gross-ups in the event of a change of control related termination. No Single-Trigger Employment Agreements Any cash payments in executive employment agreements are subject to a “double-trigger” change in control condition. Compensation Component Overview     No Hedging or Pledging Directors and executives are prohibited from hedging, pledging, or engaging in any derivatives trading with respect to Company stock. No Backdating or Repricing of Stock Options Stock options are never backdated or issued with below-market exercise prices. Repricing of stock options without stockholder approval is expressly prohibited. No Single-Trigger Stock Grants Equity compensation awards are subject to a “double-trigger” change in control condition. The following is an overview of our 2022 executive compensation program which was approved by the Compensation Committee in place prior to 2022. The 2022 plan design and awards resulted in 9% of base salary, 13% of target annual cash incentive plan, and 78% of target LTI for our current CEO and the following pay elements, metrics, and average target pay mix for all of our NEOs: 2022 Pay Elements Base Salary Award Type Mix Purpose Cash 14% To recognize individual contribution, time in role, scope of responsibility, leadership skills and experience. Annual Cash Incentive Plan Cash 17% To reward executives for performance on key operational and financial measures, with emphasis on individual contribution. Long-Term Incentive Awards Performance-based Restricted Stock Units (PSUs) Service-based Restricted Stock Units (RSUs) Equity Equity Performance-based Stock Options Equity Cash Long-term Incentive Cash To retain and motivate executives to drive long-term stockholder value and align their actions to drive successful business outcomes. 69% The performance-based stock options and cash long- term incentives were awarded in 2021 for many of our NEOs (prior to the Board and committee refreshment in 2022). Beginning in 2023, we will grant annual awards in March and eliminate performance based-stock options or cash long-term incentives.                     Proposal 2 – Advisory Resolution to Approve Executive Compensation 77 Base Salary Annual Incentives Long-Term Incentives Performance Measure g Adjusted Diluted EPS Target g Quality, Member, and Provider Satisfaction Business Unit Goals / Individual Performance Objectives The 2022 Annual Cash Incentive Plan pool was not funded unless the Adjusted Diluted EPS objective was achieved.

This pay mix exemplifies that the fixed amount of compensation is only 10% for our CEO and, on average, 17% for all NEOs, resulting in approximately 83% of pay being variable for all NEOs. The graph below illustrates the 2022 values contained in the Summary Compensation Table as percentages of total compensation. The values in the “All Other Compensation” column of the Summary Compensation Table have been excluded from this illustration. Beginning with the 2023 compensation cycle, the Company began awarding long-term incentives in March instead of the previous December. This transition and the death of our former CEO are creating some anomalies in our 2022 pay mix and do not represent the future pay mix expectations. 90% Performance-based CEO pay Base Salary Annual Incentive Long-Term Incentive Alignment of Pay and Performance We are a healthcare leader with almost $145 billion in total revenues, ranking No. 26 on the Fortune 500 list, and again have been named to Fortune’s 2023 list of World’s Most Admired Companies for the fifth consecutive year. In 2022, the Company delivered growth in revenues and adjusted diluted EPS, which was key to our strategy to promote long-term stockholder value in a competitive business environment. Our revenues increased 15% over 2021, with a 25% three-year compound annual growth rate, and our stock price remained relatively flat with depreciation of 0.5% during 2022, compared to the S&P 500 index depreciation of 19.4%. Our NEOs’ total incentive compensation opportunities are contingent on their ability to achieve profitable growth and improve margins that will provide a basis for increasing sustainable long-term value for our stockholders. When reviewing the NEOs’ compensation with our independent executive compensation consultant, the Compensation Committee considered these objectives in conjunction with our executive compensation program in continuing to recognize our pay for performance through the following three primary components: Base Pay Cash Awards Under Our Annual Incentive Plan Long-Term Incentives • Performance-Based RSUs • • • Time-Based RSUs Performance-Based Stock Options Cash LTIP The Board of Directors acknowledged this success and the importance of our CEO’s leadership as she led the Company in focusing on advancing initiatives across the enterprise to deliver on the Value Creation Plan commitments and the 2022 operational objectives. The Compensation Committee, together with our independent executive compensation consultant, analyzed the historical compensation of the Company’s CEOs. Based on their review, they determined that total compensation in 2022 is aligned with the overall growth in revenues, our total shareholder return (TSR), and adjusted diluted EPS. 10%10%10%12%31%27%16%21%28%24%17%20%55%73%40%36%62%66%73%68%14%44%43%LondonAsherFasolaMurrayKosterNeidorffLaytonThomas80 Centene Corporation Our CEO’s total compensation (where 2018-2021 was earned by Michael Neidorff; 2022 was earned by Sarah London) alignment with these metrics is illustrated in the following graphs: TSR and CEO Total Compensation TSR Indexed to $100 on December 31, 2018 Revenue and CEO Total Compensation Former CEO Total Compensation (excluding All Other Compensation), $ in millions Current CEO Total Compensation (excluding All Other Compensation), $ in millions TSR Former CEO Total Compensation (excluding All Other Compensation), $ in millions Current CEO Total Compensation (excluding All Other Compensation), $ in millions Revenues, $ in billions Diluted EPS/Adjusted Diluted EPS and CEO Total Compensation Former CEO Total Compensation (excluding All Other Compensation), $ in millions Current CEO Total Compensation (excluding All Other Compensation), $ in millions Diluted EPS Adjusted Diluted EPS $25.5$25.9$24.4$20.2$13.0$100$109$104$143$14220182019202020212022$25.5$25.9$24.4$20.2$13.0$60.1$74.6$111.1$126.0$144.520182019202020212022$25.5$25.9$24.4$20.2$13.0$2.26$3.14$3.12$2.28$2.07$3.54$4.42$5.00$5.15$5.7820182019202020212022Proposal 2 – Advisory Resolution to Approve Executive Compensation 81 The Decision Making Process Roles and Responsibilities Management reviews the Company's compensation plan design and the Company's results against established metrics. The CEO evaluates the other NEOs' contributions to those results and recommends compensation to the Compensation Committee. The Compensation Committee evaluates the Company, CEO, and other NEOs' performance against metrics. FW Cook advises management and the Compensation Committee on the appropriateness of compensation and plan design based on market comparison. The Board of Directors determines the CEO compensation and the Compensation Committee determines and approves other NEOs' compensation and the overall compensation plan design. Competitive Pay Design Our compensation and benefit practices are designed to attract and retain the best talent and achieve aggressive operating objectives. Programs are designed to both motivate our employees and reward them for exceptional performance. The Company views both private equity firms and competitors with larger market capitalization as significant competition for talent. We also recognize that our Company is a source for these firms and competitors to recruit talent if the appropriate compensation programs are not in place. For the components of target total compensation, the Compensation Committee’s objectives are for base salaries, short- term incentives, and total target compensation to be targeted at the median of peer group practice (or applicable survey sources). Long-term incentives are granted at levels, which when combined with base salary and target short-term incentives, result in the desired competitive positioning of total target compensation. Differences from the market median may be considered for a variety of factors, including performance, retention, tenure, and recruitment requirements. In order to achieve these objectives, the Compensation Committee establishes target, market-based total compensation levels (e.g. base salary, annual bonus target, and long-term incentives) from market data from two different peer groups. Healthcare Industry Peer Group Using the Standard and Poor’s Global Industry Classification System (GICS) codes and other relevant industry parameters, Exequity, LLP (Exequity), the Company's compensation consultant until May 2022, analyzed the managed care industry and determined there are four key segments in the industry: • Managed Healthcare Companies; • Healthcare Distributors; and • Healthcare Services; • Healthcare Facilities. Based on further review by Exequity, the following companies were included in the Company’s Healthcare Industry (HCI) Peer Group for use in determining compensation for NEOs in 2022, which was consistent with the peer group used for 2021: Managed Health Care (Direct Competitors) • Cigna Corporation • Molina Healthcare, Inc. Healthcare Distributors • AmerisourceBergen Corporation Healthcare Services • CVS Health Corporation • • Elevance Health, Inc. • UnitedHealth Group, Inc. Humana, Inc. • • Cardinal Health, Inc. McKesson Corporation Healthcare Facilities • HCA Healthcare, Inc. Based on data compiled by Exequity at the time of the peer group review, our positioning on key financial metrics relative to the peer group was as follows: market capitalization - 39th percentile; revenue - 31st percentile.   82 Centene Corporation In May 2022, the Company appointed Frederic W. Cook & Co., Inc. (FW Cook) as its independent compensation consultant. Based on FW Cook’s review, Walgreens Boots Alliance, Inc. will be added to the HCI Peer Group for 2023 compensation decisions. General Industry Group Since there is a market for executive talent both within and outside our industry, we also benchmark against the general industry. Therefore, the market data the Compensation Committee utilizes includes not only the HCI Peer Group, but also a General Industry (GI) peer group of approximately 400 companies derived from the Willis Towers Watson Compensation Database. Benchmarking Methodology The Compensation Committee’s prior compensation consultant, Exequity, gathered, analyzed, and summarized the market data from the Willis Towers Watson Executive Compensation Database for the CEO and the other NEOs. For this analysis, which is utilized in determining 2022 compensation for the forthcoming year, including base salaries, annual cash incentive targets, and LTIP targets, we size-adjust the general industry peer data to be in line with our forecasted revenues for the upcoming year. All elements of compensation are valued and reviewed in evaluating the relative competitiveness of our compensation practices against both market data and the Compensation Committee’s competitive objectives. In addition, the Compensation Committee annually reviews a tally sheet for each NEO, which includes the current value of all outstanding equity-based awards, benefits, and perquisites. The Compensation Committee uses the tally sheets to analyze each NEO’s base salary, annual incentive target and long-term incentive opportunity in relation to the market and each component of compensation as a percentage of total compensation to determine if there is any risk of retention of key executives. A similar analysis of peer data sets is performed on the other NEOs’ compensation. The Compensation Committee, Chairman, and CEO review the performance of each individual and align compensation based on this analysis. Risk Disclosure The Compensation Committee is aware of the consequences to companies that have not appropriately balanced risk and rewards in executive compensation. The Compensation Committee believes that the emphasis on long-term performance in the incentive plan results in an overall compensation program that does not encourage or reward excessive risk-taking for the Company. Risk is further limited by the ownership guidelines mentioned previously and a clawback provision that provides that any cash bonuses that are paid from the annual incentive plan, Cash LTIP, or vesting of PSUs that are a result of material financial impropriety (as defined by the Audit and Compliance Committee of the Board), including but not limited to financial restatements due to these improprieties, may result in any officers becoming obligated to pay back the amount to the Company. The Company’s compensation strategy is intended to mitigate risk by emphasizing long-term compensation and financial performance measures correlated with growing stockholder value rather than rewarding shorter performance and payout periods. A recent review of the Company’s compensation programs by the Compensation Committee, with the support of FW Cook, did not identify any programs that unduly incentivize employees to take any excessive risks. Proposal 2 – Advisory Resolution to Approve Executive Compensation 83 2022 Executive Compensation Program The 2022 compensation plan design and metrics were developed by prior leadership and prior to the refreshment of the Board of Directors and Compensation Committee. The 2023 compensation plan design and metrics contain substantial changes that are highlighted in the letter from the Compensation Committee Chairman and outlined in this Compensation Discussion and Analysis. The following is an overview of our 2022 executive compensation program which was approved by the Compensation Committee in place prior to 2022. Base Salary In December 2021, the Compensation Committee evaluated the 2022 base salaries of our NEOs and took into account the Company’s 2021 estimated revenue of approximately $125 billion. Our NEOs’ base salaries were compared to competitive market data and the Compensation Committee believed that selective increases in base salaries were only required for Ms. London and Mr. Asher in connection with their new employment agreements and therefore no further salary adjustments were made for 2022. Mr. Asher's base salary was increased to $1.025 million in connection with his updated employment agreement and Ms. London's base salary was increased to $1.4 million in connection with her appointment to CEO. The NEOs were paid competitive base salaries determined by the evaluation of multiple factors: business results for the prior year, individual performance, and the market value for each specific job. Since Centene is a pay for performance company, only 10% of the CEO’s compensation is comprised of base salary and, on average, 17% of the other NEOs’ compensation is comprised of base salary. Beginning with the 2023 compensation cycle, the Company began awarding long-term incentives in March instead of the previous December. This transition and the death of our former CEO are creating some anomalies in our 2022 pay mix and do not represent the future pay mix expectations. While reviewing market data to determine appropriate annual base salaries, the Compensation Committee also considers: • • • • the CEO’s compensation recommendations for all other NEOs; the scope of responsibility, experience, time in position, and individual performance of each executive, including the CEO; each executive’s leadership performance and potential to enhance long-term stockholder value; and internal equity. Annual Cash Incentive Plan Based on a review of industry data, the Compensation Committee approved an annual cash incentive plan target opportunity in 2022 of 150% of base salary for Ms. London, Mr. Neidorff and Mr. Layton, 125% of base salary for Mr. Asher, and 100% of base salary for the other NEOs. The Compensation Committee rewards NEOs with an annual cash incentive bonus if the Company achieves its Adjusted Diluted EPS objective. The allocation of the bonus payout is based on multiple metrics. A. Must Meet Adjusted Diluted EPS Objective (Funding of Bonus) % of Target Adjusted Diluted EPS Metric Criteria Threshold 50% $5.15 Target 100% $5.40 Maximum 200% $5.80 If the Company does not meet its threshold Adjusted Diluted EPS objective, no payments are made. Refer to Appendix A for reconciliations of non-GAAP measures included throughout this proxy statement. 84 Centene Corporation B. Allocation of Bonus Payout Metric Adjusted Diluted EPS Business Unit & Individual Goals Quality, member, and provider satisfaction Weight 50% 40% 10% 100% The Compensation Committee then followed a multi-step process to determine the bonus earned for 2022: 01 Achievement of Adjusted Diluted EPS Objective The Company’s 2022 Adjusted Diluted EPS was determined. 02 Evaluation of Quality, Member and Provider Satisfaction The Compensation Committee assessed the Company’s achievement of quality, member, and provider satisfaction against the Company’s annual business plan using key metrics such as Centers for Medicare & Medicaid Services (CMS) Medicare Star ratings and Medicaid Healthcare Effectiveness Data and Information Set (HEDIS) measures. The Medicare Star ratings evaluated for the 2022 bonus are the result of efforts performed in 2022, impacting the 2025 revenue year. 03 Evaluation of Business Unit Performance The Compensation Committee assessed the Company’s achievement of certain financial and operational business unit performance goals, including: • Achievement of value creation milestones, including selling, general and administrative (SG&A) activities, pharmacy benefits manager (PBM) RFP process, and strategic capital deployment; • • Portfolio review execution, including divestitures and asset repositioning; and Profitable growth, including marketplace margin improvement & Medicaid RFP performance. The Compensation Committee considered these additional aggregate business unit metrics: • Adjusted pre-tax margin • Employee engagement • • Health benefits ratio (HBR) • Compliance Adjusted SG&A ratio 04 Evaluation of Individual Performance Based on input from management, the Compensation Committee assessed each NEO’s individual performance against pre-determined goals and overall determined that goals of the NEOs were met at target. Proposal 2 – Advisory Resolution to Approve Executive Compensation 85 Achievement of Adjusted Diluted EPS Objective The Adjusted Diluted EPS objective is established during our annual operating planning process. Our annual bonus plan is developed each year based on a pay-for-performance approach with rigorous performance metrics that the Compensation Committee believes are challenging but attainable for our short-term and long-term incentive programs. In addition, the performance metrics align closely with our business environment and incorporate initiatives and investments during the year that will extend beyond near-term benefits and will also support favorable longer-term impact on our business. While the Company continues to execute on a rigorous growth strategy, the Compensation Committee continues to set metrics that reflect a continued focus on increased profitability. As illustrated below, based upon the approved Adjusted Diluted EPS metrics, the Compensation Committee had increased these profitability targets for 2022. The Compensation Committee exercised negative discretion on the Adjusted Diluted EPS metric and reduced the reported result of $5.78 by $0.02 for share repurchases not included in the annual operating plan and funded from free cash flow from operations, resulting in an achievement of 190% for funding and the allocation using this metric. However, the pool was reduced by 5% based on quality outcomes as discussed below. Threshold % of Target 50% 2022 Target   100%   Maximum 200%  Evaluation of Quality, Member, and Provider Satisfaction We track internal forecast data around quality metrics for our business lines using dates of service in 2022 including Medicare Star ratings, National Committee for Quality Assurance (NCQA) accreditation, Consumer Assessment of Healthcare Providers and Systems survey results and Medicaid HEDIS measures for 15 priority measures. These metrics reflect the results derived from our comprehensive clinical programs designed to improve quality outcomes. The Medicare Star ratings evaluated for the 2022 bonus are the result of efforts performed in 2022, impacting the 2025 revenue year. The Medicaid HEDIS measures metric is based on 2022 membership weighted national average performance for 15 priority HEDIS measures. The Company's value creation strategy includes initiatives such as the standardization of utilization management, pharmacy platform consolidation, and operational enhancements to improve these quality metrics. The Company has not disclosed the specific threshold, target, and maximum metric amounts as we view these metrics as confidential, and disclosure would create competitive and commercial harm. Quality outcomes for 2022 dates of service resulted in the achievement of 136% of this metric. The results of our quality metrics are shown below: Threshold % of Target 50% Quality Target   100%   Maximum 200%  While the 2022 bonus plan provides for Adjusted Diluted EPS to fund the pool, the Compensation Committee exercised negative discretion and reduced the funding pool by 5% as a result of the quality metrics. The bonus funding pool was intentionally reduced from 190% to 185% to hold all employees accountable for quality outcomes. 86 Centene Corporation Evaluation of Business Unit Performance The evaluation of business unit performance involved a review of performance of executive leadership goals and consideration of additional aggregate enterprise metrics. Our business unit goals include the initiatives developed under our Value Creation Plan, which create additional short-term value and to seek opportunities that position the organization for long-term strength, profitability, growth, and innovation. In 2022, we completed all of our value creation milestones, including the centralization of utilization management, capital deployment, and real estate optimization. The Company successfully negotiated an external PBM contract, exceeding its projected savings targets. The Company has completed seven divestitures since the initiation of the Value Creation Plan in 2021, with six of them negotiated in 2022. A full list of 2022 value creation milestones are shown below the performance metric achievement. Threshold % of Target 50% Target   100%   Maximum 200%  Value Creation Milestones Portfolio Review Execution PBM RFP Value Creation: Measuring Progress in 2022 The Company outperformed in profitable growth, including our Marketplace margin improvement, successful reprocurements and contract expansions in Iowa, Louisiana, Mississippi, Missouri, Nebraska, Nevada, Texas (Foster Care), and Washington. In addition, the Company was awarded a new contract in Missouri as the sole provider of the newly awarded Specialty Plan, serving foster children and children receiving adoption subsidy assistance. The Company was also awarded and commenced a new contract for the statewide Medicaid contract in Delaware, it's 30th Medicaid state. The Company's profitable growth success was partially offset by lost market share in California and the negative impact the initial announcement had on our TSR. Proposal 2 – Advisory Resolution to Approve Executive Compensation 87 The results of our performance against these business unit goals are shown below: Threshold % of Target 50% Target   100%   Maximum 200%  Profitable Growth Success California RFP results The Compensation Committee also considered these additional aggregate business unit metrics. The Company met or exceeded all of the targets, with the exception of the adjusted SG&A expense ratio due to intentional marketing costs and value creation investments. Centene’s 2022 overall engagement score exceeded the Fortune 100 75th top quartile benchmark, at 88% favorability. The results of our performance against these aggregate metrics are shown below: Threshold % of Target 50% Target   100%   Maximum 200%  Pre-Tax Margin (As adjusted)1 HBR Adjusted SG&A Ratio Employee Engagement Compliance • • New Compliance leader; meaningful progress on Compliance discipline Specific Compliance metrics not applicable evenly to all NEOs 1 Pre-tax Margin (As adjusted) represents a non-GAAP measure. Refer to Appendix A for reconciliations of non-GAAP measures throughout this proxy statement. 88 Centene Corporation Evaluation of Individual Performance The Compensation Committee assessed how each NEO contributed to achieve the Company's Adjusted Diluted EPS objective and other pre-determined objectives approved by the Compensation Committee at the beginning of the year. An evaluation of each NEO's individual contribution towards the business unit goals is described below in detail, along with their bonus payout percentage based on their performance. 2022 Annual Cash Incentive Paid ($) % of Target Paid $3,683,466 180% $2,303,777 183% Name Individual Performance Sarah M.

Therefore, no annual grants were made to Ms. London, Messr. Asher, Koster, Layton, and Thomas in 2022. Mr. Fasola and Mr. Murray received annual awards in March 2022 as they joined the Company in January 2022 in connection with the Magellan Health, Inc. (Magellan) acquisition. Those annual awards consisted of the following: • Performance-based Restricted Stock Units (PSUs) (60% of shares granted) - The target metrics for the 2022-2024 performance period are 2024 Adjusted Diluted EPS of a target of $7.62 (70% weight) and adjusted net earnings margin of 3.30% by 2024 (30% weight). Threshold, target, and maximum metric achievement will result in 50%, 100%, or 200% attainment of each metric, respectively. If earned, PSUs will vest in February 2025. • • Service-based Restricted Stock Units (RSUs) (40% of shares granted) - One-third vest annually based on continued service with the Company. Cash Long-Term Incentive Plan (Cash LTIP) - The target metrics for the 2022-2024 performance period are 2024 Adjusted Diluted EPS of $7.62 (35% weight) and Adjusted Net Earnings Margin of 3.30% by 2024 (15% weight), as well as a relative Total Shareholder Return objective (50% weight). Threshold, target and maximum metric achievement will result in 50%, 100% or 200% attainment of the metric respectively, while the threshold level of achievement for the Total Shareholder Return metric will be set at the 25% attainment level. Beginning in 2023, the Company will grant long-term incentives (LTI) to all executives in March. In addition, we have eliminated performance-based stock options and Cash LTIP from our compensation plan design. 2022 Off-Cycle LTI The Compensation Committee also granted LTI to our NEOs in 2022 as off-cycle awards related to employment agreements, the Magellan acquisition or retention awards. Ms. London was awarded PSUs in connection with her promotion to CEO. Mr. Asher and Mr. Layton were awarded LTI pursuant to their employment agreements in the form of PSUs and/or RSUs. Mr. Fasola and Mr. Murray were awarded LTI upon joining the Company in January 2022 in connection with the Magellan acquisition in the form of RSUs and Cash LTIP. Mr. Thomas was awarded a retention LTI in the form of an RSU. 2020-2022 Performance-Based Restricted Stock Unit Award Results In December 2019, the Compensation Committee established the following metrics, targets and weights for the 2020-2022 PSUs. The Company results of both targets as shown below with a total percentage earned at 102.4% of the target: Threshold Target Maximum Weight Metric Payout of Target Weighted Payout Pre-Tax Margin (As adjusted)1 Compound Annual Revenue Growth Rate 60% 82.7% 49.6% 40% 132.0% 52.8% 100% 102.4% 1 Pre-tax Margin (As adjusted) represents a non-GAAP measure.

Other Benefits We provide our NEOs with a defined contribution 401(k) retirement program, which is the same program that is generally provided to all our employees. We also provide our NEOs with a non-qualified deferred compensation plan to make up for matching contributions that are capped by compensation limits imposed on qualified retirement plans under the Internal Revenue Code. We do not provide our NEOs with a defined benefit retirement program. We also do not provide retiree medical coverage to our NEOs, with the previous exception of Mr. Neidorff, as was specified in his employment agreement. With respect to most other benefits, the benefits provided to NEOs and other executive officers are comparable to those provided to the majority of salaried and hourly Company employees. In 2022, NEOs had the option to have their tax returns prepared or reviewed by an independent certified public accounting firm, and costs related to these services were paid by the Company. In addition, each NEO had the option to use a financial advisor for fees that do not exceed $15,000 annually, in total, for both tax preparation and financial advisement. These costs are also fully taxable to them and are not grossed up to cover any personal income tax liability. Additionally, other benefits can include relocation, premiums for life insurance benefits, and Company entertainment event tickets. For 2023, the Company has eliminated the tax preparation and financial advisement benefit to better align the overall compensation program with our pay for performance philosophy. Certain NEOs may use the aircraft for personal travel pursuant to the terms of their employment agreements. In addition, we provide home security services to our NEOs. The personal use of Company provided aircraft and home security services are fully taxable to our NEOs and are not grossed up to cover any personal income tax liability. 94 Centene Corporation 2023 Compensation Decisions 2023 Annual Cash Incentive The Compensation Committee rewards NEOs with an annual cash incentive bonus for achieving the Company’s Adjusted Diluted EPS objective, business unit and individual goals, and quality metrics. Annually, the Compensation Committee assesses how each NEO contributed to achieving the Adjusted Diluted EPS objective and the other pre-determined objectives approved by the Compensation Committee. The Adjusted Diluted EPS objective is established during our annual business planning process. Our annual bonus plan targets are developed each year based on a pay for performance mentality with rigorous performance metrics at target that the Compensation Committee believes are challenging but attainable for our short-term and long-term incentive programs and stretch goals to reach to pay above target. For 2023, Adjusted Diluted EPS no longer funds the pool to better align funding with payouts. 2023 Bonus Metrics Metric Adjusted Diluted EPS Business Unit & Individual Goals Quality, member, and provider satisfaction Weight 65% 25% 10% 100% The Compensation Committee will assess and evaluate how each NEO contributed to achieving this Adjusted Diluted EPS objective and the other pre-determined objectives stated above. Individual awards under our bonus plan are approved by the Compensation Committee based primarily upon: • business performance versus our business plan; • • • the effectiveness of each executive’s leadership performance and potential to enhance long-term stockholder value; targeted bonus amounts, which are based upon market data; and the recommendation of the Chief Executive Officer (for all NEOs other than the CEO). Overall, 65% of each award is aligned with the Adjusted Diluted EPS target, 10% is based on specific metrics tied to quality of the overall company, and the remaining 25% is aligned with specific business unit performance goals. TARGET INCENTIVE OPPORTUNITY PERFORMANCE Base Salary Individual Target Award % Adjusted Diluted EPS Performance Business Unit & Individual Goals Quality Objectives Range: 0% to 200% Range: 0% to 200% Range: 0% to 200% Multiplied by 65% Weight Multiplied by 25% Weight Multiplied by 10% Weight Annual Cash Incentive Award (Maximum @ 200% of Target) Proposal 2 – Advisory Resolution to Approve Executive Compensation 95 Adjusted Diluted EPS Objective % of Target Adjusted Diluted EPS Business Unit and Quality Objectives Metric Criteria Threshold 50% $5.70 Target 100% $6.32 Maximum 200% $7.10 In 2023, we will continue to focus on long-term stockholder value through meeting our financial metrics that are measurable against key financial and operational priorities. As part of our Quality objectives, we have goals that are tied to key quality metrics for service dates in 2023. 2023-2025 Long-Term Incentives Our long-term incentive compensation is designed to attract and retain key executives, build an integrated management team, reward for innovation and appropriate risk-taking, balance short-term planning with long-term successes, and align executive and stockholder interests. This includes using relative TSR, adjusted pre-tax earnings growth, and adjusted net earnings margin targets. The relative TSR target is above the median. If the Company’s TSR for the performance period is negative, then the payout for this component will not exceed 100% of target. Annual grants are based on performance but are guided by market practices. These long-term incentives take the form of the following: • PSUs (65% of stock granted) that are based on meeting predetermined performance targets (TSR, adjusted pre-tax earnings growth and adjusted net earnings margin) vest at the end of the three-year performance period. • RSUs (35% of stock granted) that vest ratably over three years. Long-term incentives are provided through equity (PSUs at 65% and RSUs at 35%), while ensuring that the maximum number of shares of common stock granted in any calendar year (excluding shares granted in connection with an acquisition) does not exceed a level associated with competitive practice. Excluding acquisitions, the Company does not annually grant equity compensation exceeding 2% of the outstanding shares of the Company. In 2022, our run rate was 0.5%. Due to the growth of the Company, the competitive nature of our business, and the necessity of retaining key management level employees, equity grants can be awarded to levels below senior executives. Beginning in 2023, annual PSU and RSU awards will be granted in March, but may also be approved at other times for a promotion, extraordinary performance, a newly hired executive or as determined by the Compensation Committee.

Fasola, James E. Murray, and Brent D. Layton, and with Michael F. Neidorff prior to his death on April 7, 2022, and severance and change in control agreements with Christopher A. Koster and David P. Thomas. The Board has determined that it is in the best interests of the Company and our stockholders that our executives enter into employment agreements to ensure a commitment to individual duties, compliance with restrictive covenants, and the continued dedication of the executive, notwithstanding the possibility, threat, or occurrence of a termination of employment, in particular upon a change in control. The Board believes it is imperative to diminish the inevitable distraction of the executive by virtue of the personal uncertainties and risks created by a pending or threatened change in control, to encourage the executive’s full attention and dedication to the Company, and to provide the executive with compensation and benefits arrangements upon a change in control which (i) will satisfy the executive’s compensation and benefits expectations, and (ii) are competitive with those of other major corporations. 96 Centene Corporation On March 21, 2022, the Board of Directors appointed Ms. London, previously the Company’s Vice Chairman and a member of the Office of the Chairman, to the position of CEO of the Company, effective immediately, succeeding Michael F. Neidorff. Ms. London is party to an employment agreement dated April 27, 2022, entered into in connection with her appointment to the role of CEO. Pursuant to an employment agreement dated April 28, 2022, Mr. Asher agreed to continue serving as our Chief Financial Officer. In an effort to further align our executives’ compensation with the interests of stockholders and promote corporate best practices, Ms. London and Mr. Asher’s employment agreements were amended on February 20, 2023 to eliminate multi-year guaranteed long-term compensation awards. Future long-term compensation awards shall be annually determined by the Compensation Committee in its sole discretion. The Company entered into employment agreements with Messrs. Fasola and Murray on February 20, 2023, pursuant to which Mr. Fasola agreed to serve as our President and Mr. Murray agreed to serve as our Executive Vice President and Chief Operating Officer. Pursuant to an executive employment agreement with Mr. Layton, dated May April 27, 2022, Mr. Layton agreed to serve as our President and Chief Operating Officer. On December 13, 2022, Mr. Layton entered into an amendment to this employment agreement in which he agreed to serve as Senior Advisor to the CEO, until his planned retirement later in 2023. Michael F. Neidorff served as Chairman of our Board and CEO pursuant to an employment agreement dated November 8, 2004 (as subsequently amended). In connection with this death, Mr. Neidorff's estate was eligible to receive a pro-rated target annual incentive of 150% of base salary for 2022 based on actual performance. The agreement also awarded Mr. Neidorff 500,000 RSUs (split adjusted three times to 4,000,000) as of November 8, 2004. The RSUs and all of the related shares of common stock were distributed to Mr. Neidorff's estate on January 15, 2023, the first calendar year following termination of Mr. Neidorff’s employment by death. Mr. Neidorff's estate vested fully in all of his outstanding service-based long-term incentive awards upon his death and shall continue to vest in any outstanding long-term incentives (subject to any performance measures to be determined at the end of the applicable performance period). In addition, for the reasons outlined above, the Board has determined that it is appropriate for senior executives who are not party to individual employment agreements providing for severance, including Mr. Koster and Mr. Thomas, be party to executive severance and change in control agreements. For a summary of the material terms of our executive employment agreements and termination provisions, see “Individual Agreements” on page 103 and “Potential Payments Upon Termination or Change in Control” on page 109. Under the terms of any new employment agreement or executive severance and change in control agreement, if any parts or amounts payable under the agreement are deemed to be “excess parachute payments” within the meaning of Section 280G of the Code or similar provision, the amount shall be reduced to the extent necessary so that no amounts paid shall be deemed excess parachute payments or, if the net benefit is greater, no reduction will be made, but the executive will be required to pay any additional taxes. No agreement provides for an excise tax gross-up. In the agreements, the executives agree to non-competition and non-solicitation provisions that extend through the first anniversary of termination of employment, unless the termination was due to a change in control. Retirement Provisions In addition, for all Company employees, Company awards include a qualified retirement definition. NEOs who are at least 55 years of age and have 10 years of employment at the time of retirement are eligible for the following: • A pro-rated number of PSUs vesting at the end of the performance period, based on the amount of time employed during the performance period and actual performance outcomes. • • • A one-year acceleration of vesting of RSUs for individuals who are retirement eligible. RSUs for the Company’s executive officers are not accelerated, but will have a one-year continuation of vesting upon a qualified retirement. A pro-rated amount of cash LTIP vesting at the end of the performance period, based on the amount of time employed during the performance period and actual performance outcomes. A pro-rated annual paid bonus, if employed for six months of the calendar year, paid at actual performance generally at the same time when bonuses are paid to other employees. Proposal 2 – Advisory Resolution to Approve Executive Compensation 97 Stock Ownership Guidelines We utilize stock ownership guidelines for our NEOs, corporate officers and Board. We believe that ownership of our stock helps align the interests of our executives and stockholders, and encourages executives to act in a manner that is expected to increase stockholder value. The stock ownership guidelines for our officers are as follows: Chief Executive Officer President & Executive Vice Presidents Senior Vice Presidents Market & Specialty Company Presidents & other Corporate Executives Minimum Ownership Requirement as a Multiple of Base Salary 5x 2.5x 2x 1x The Compensation Committee annually reviews the stock ownership levels of the Board and all officers. Future stock awards take into consideration the executive’s level of attainment of the suggested stock ownership amount. The Compensation Committee may elect to award the annual incentive to an executive in stock instead of cash if the suggested stock ownership amount is not achieved. Officers who fail to achieve these ownership levels may not be eligible to receive any stock-based awards until they achieve their required ownership level. Shares owned directly by the officer (including those held as a joint tenant or as tenant in common), unvested RSUs, shares owned in a self-directed IRA, “phantom shares” held in the deferred compensation plan, and certain shares owned or held for the benefit of a spouse or minor children are counted toward the guidelines. Options and unearned PSUs are not counted toward the ownership guidelines. The Board has established a policy requiring executive officers to retain ownership of the shares received from the vesting or payout of any RSU award granted under our stock incentive plan (net of any shares used to satisfy tax obligations) for one year following such vesting or payout. An executive may substitute the tax basis of the shares under restriction for other shares held outright. As of the close of the last fiscal year and the date of this report, all NEOs subject to the ownership guidelines are in compliance with the guidelines. At $82.01 per share (the December 31, 2022 closing stock price), our executive officers held Company stock as of a multiple of their ending 2022 base salaries as follows: Name Sarah M. London Andrew L. Asher Kenneth J. Fasola James E. Murray Christopher A. Koster Brent D. Layton David P. Thomas Minimum Ownership Requirement as a Multiple of Base Salary Ownership as a Multiple of 2022 Base Salary 5x 2.5x 2.5x 2.5x 2.5x 2.5x 2.5x 10.9x 19.2x 13.3x 14.1x 11.2x 34.3x 5.8x Stock ownership guidelines for members of our Board require them to own 7.5 times the annual cash retainer within five years of being appointed to the Board. As of December 31, 2022, all directors were in compliance with this requirement. 98 Centene Corporation Hedging and Pledging Policy The Board maintains the Company’s insider trading policy, which prohibits pledging of shares by executive officers and members of the Board. Our insider trading policy also prohibits members of the Board and any employees from engaging in short-term or speculative transactions involving our securities. Our insider trading policy provides that members of the Board and employees may not engage in short sales of our securities, including short sales “against the box,” or purchase sales of puts or calls for speculative purposes. As of March 13, 2023, all executive officers and directors were in compliance with these policies. Deductibility of Executive Compensation Section 162(m)(6), which was enacted as part of the Patient Protection and Affordable Care Act, amended the Code to limit the amount that certain healthcare insurers and providers, including the Company, may deduct for compensation to any employee in excess of $500,000 for a tax year beginning after December 31, 2012. This legislation does not create any exceptions for performance-based compensation and is not otherwise impacted by the adoption of the Tax Cuts and Jobs Act enacted on December 22, 2017. The Compensation Committee reserves the right to use its judgment to authorize compensation payments that may be subject to the limit when the Compensation Committee believes such payments are appropriate and in the best interests of our stockholders, after taking into consideration changing business conditions and the performance of its employees. We were subject to the limitation in 2022. Proposal 2 – Advisory Resolution to Approve Executive Compensation 99 Compensation and Talent Committee Report The Compensation and Talent Committee, comprised solely of independent directors, has reviewed and discussed the “Compensation Discussion and Analysis” with the Company’s management. Based on this review and discussion, the Compensation and Talent Committee recommended to the Board of Directors that the “Compensation Discussion and Analysis” be included in this proxy statement on Schedule 14A and incorporated by reference into the Company’s Annual Report on Form 10-K for the year ended December 31, 2022.

Additional descriptions of each component of compensation for our NEOs are included elsewhere in this Proxy Statement under the caption, “Compensation Discussion and Analysis.” For 2022, our NEOs included our Chief Executive Officer, Chief Financial Officer, President, Chief Operating Officer, and Secretary and General Counsel. In addition, as required by SEC rules, we also include as NEOs our former Chairman and Chief Executive Officer, Michael F. Neidorff, as well as Brent D.

Mr. Layton and Mr. Thomas are included as they otherwise would have been NEOs except for the fact that they were not serving as an executive officer at the end of 2022. Mr. Layton and Mr. Thomas remain with the Company in non-executive officer roles. Name & Principal Position Sarah M.

Asher, Fasola, Murray, Layton, and Thomas, reflect the grant date fair value of grants made during the current year under the 2012 Stock Incentive Plan computed in accordance with FASB ASC 718. Note 15 to the Notes to Consolidated Financial Statements of our Annual Report on Form 10-K for the year ended December 31, 2022, describes the assumptions used to determine the grant date fair value for overall Company equity awards. There can be no assurance that the grant date fair value of stock awards will ever be realized. Stock awards granted to the NEOs include performance-based restricted stock units. Performance-based units are disclosed at target value. The 2022 performance-based restricted stock units have a maximum payout of 200%. If the maximum performance metrics are achieved, the grant date fair value of the performance awards would be $15,249,948 for Ms. London, $5,999,942 for Mr. Asher, $3,600,014 for Mr. Fasola, $899,962 for Mr. Murray, and $3,119,962 for Mr. Layton. Proposal 2 – Advisory Resolution to Approve Executive Compensation 101 2 3 The amounts shown in the Non-Equity Incentive Plan Compensation column include both the annual cash incentive and the Cash LTIP award payouts.

Note: Certain NEOs utilized timeshare agreements with the Company in which they reimbursed the Company for personal aircraft usage, based on an amount approximately equal to the variable cost of operating the aircraft. Any such amounts are not included in the table above as there is no incremental cost to the Company. 102 Centene Corporation Grants of Plan-Based Awards Table The following table provides information on 2022 grants of performance and service-based restricted stock units and performance-based stock options, under the 2012 Stock Incentive Plan, as well as 2022 cash-based grants under the Cash LTIP and Annual Cash Incentive Plan to each of our NEOs.

Beginning in 2023, the Company moved to granting all awards in March. As a result, no awards were granted in December of 2022. Awards for the 2022 compensation year were granted in December 2021 and are excluded from the table above as they were reported in the 2022 Proxy Statement. All awards reported herein represent off-cycle awards and annual awards for NEOs joining the Company in 2022. 1 No awards were granted for Mr. Koster in 2022 due to changes in the timing of annual awards as discussed above. 2 The amounts shown in the Estimated Future Payouts Under Non-Equity Incentive Plan Awards columns represent the range of the annual cash incentive awards as described in the section titled “Annual Cash Incentive Plan” in the Compensation Discussion and Analysis, above. In addition, the awards include the long-term cash incentive awards for the 2022 - 2024 performance cycle and the 2021 - 2023 performance cycle. Awards for the 2021 - 2023 performance year were awarded to Mr. Fasola and Mr. Murray upon joining the Company in January 2022 in connection with the Magellan acquisition. No awards were granted to other NEOs due to changes in the timing of awards as discussed above. Proposal 2 – Advisory Resolution to Approve Executive Compensation 103 3 4 5 6 The amounts shown in the Estimated Future Payouts Under Equity Incentive Plan Awards columns represent the range of shares that may be earned at the end of the 2022-2024 performance period applicable to our PSUs assuming achievement of the relevant performance objectives. The amounts shown in the All Other Stock Awards column represent off-cycle RSU awards for Mr. Asher, Mr. Fasola, Mr. Murray, Mr. Layton, and Mr. Thomas. In addition, Mr. Fasola and Mr. Murray received annual awards in March of 2022 as they were not employed during the annual award process in December of 2021. The amounts shown in the Grant Date Fair Value of Stock Awards column represent the grant date fair value, measured in accordance with FASB ASC 718. Equity incentive grants contain a performance condition based upon our 2024 Adjusted Net Earnings Margin and Adjusted Diluted EPS. For performance between the threshold and the target or the target and the maximum, the number of performance-based restricted stock units earned will be interpolated. Individual Agreements The following is a description of the material terms of the employment agreements with Ms. London and Messrs. Asher, Fasola, Layton, Murray, and Neidorff. Sarah M.

The Company does not pay above market interest or preferential dividends on investments in the Deferred Compensation Plan. Investment options in the Deferred Compensation Plan are substantially the same as the 401(k) plan, with the exception of the investment in Centene common stock. The returns on the investments available to employees during 2022 ranged from -38.5% to 4.48%, with a median return of -17.62% for the year ended December 31, 2022. The amounts shown in the Aggregate Balance at Last Fiscal Year-End column include money the Company owes these individuals for salaries and incentive compensation they earned in prior years but did not receive because they elected to defer receipt of it until a later time. For fiscal year 2022, the amounts described in Footnote 1 above are included in the Summary Compensation Table. For fiscal year 2021, the following aggregate amounts of executive contributions were included in the Summary Compensation Table: Ms. London - $58,708; Mr. Asher - $54,978: Mr. Koster - $315,046; Mr. Neidorff - $270,000; Mr. Layton - $209,211. For fiscal year 2020, the following aggregate amount of executive contributions was included in the Summary Compensation Table: Mr. Neidorff - $324,000. For prior years, all amounts contributed by a NEO in such years have been reported in the Summary Compensation Table in our previously filed proxy statements in the year earned, to the extent the executive was named in such proxy statements and the amounts were so required to be reported in such tables. Represents the receipt of a previous grant of 500,000 RSUs (split adjusted three times to 4,000,000). Pursuant to the terms of the grant agreement, the receipt of the RSUs which vested from 2009 through 2014 has been deferred until retirement. The total value of the RSUs is reflected in the aggregate balance based on the December 31, 2022 market value. Proposal 2 – Advisory Resolution to Approve Executive Compensation 109 Potential Payments Upon Termination or Change in Control As previously discussed, Ms. London and Messrs.

Retirement Provisions As of December 31, 2022, both Mr. Layton and Mr. Thomas are eligible for qualified retirement treatment as described in Other Compensation Policies and Information in the CD&A. The tables below assume a voluntary termination would be the result of a qualified retirement for these NEOs. Termination and Change-in-Control Tables The section below describes the payments that may be made to our NEOs upon termination or a change in control. Our NEOs may also be entitled to payments under the Company’s Deferred Compensation Plan as set forth in the Nonqualified Deferred Compensation Table section above. The amounts presented below assume the termination or change in control occurred as of December 31, 2022, based on the employment agreements in place at December 31, 2022, in accordance with the applicable SEC rules. The change in control cash payments are subject to the conditions of the “double-trigger” criteria in each of the NEO’s employment agreement or executive severance and change in control agreements, meaning they are only entitled to payment if there is a change in control and the executive officer's employment is terminated without "cause" or the executive officer terminates his or her employment for "good reason" within twenty-four months of the change in control. The equity award acceleration amounts below were calculated using the closing price of our common stock on December 31, 2022 of $82.01. In the Change in Control column, the Cash LTIP and PSU awards are generally included at the greater of the target or actual level of performance as of December 31, 2022. Our equity award agreements include a “double-trigger” provision, which provides for accelerated vesting only if there is a change in control and the executive officer’s employment is terminated without “cause” or the executive officer terminates his or her employment for “good reason” within twenty-four months of the change in control.

Amounts disclosed below reflect compensation to our Principal Executive Officers (PEOs) and Non-PEO Named Executive Officers (Non-PEO NEOs), including compensation reflected on the Summary Compensation Table (SCT) and Compensation Actually Paid (CAP). Performance metrics include Total Shareholder Return (TSR) for the Company, TSR for the S&P Supercomposite Managed Healthcare Index effective as of December 31, 2022, Company Net Income and Adjusted Diluted EPS, which is the measure selected by the Company as the most important financial metric for determining CAP in the current year.

Since the applicable SEC rules allow companies to use a variety of methods to determine this ratio, the ratio disclosed by the Company may not be comparable to the ratio disclosed by other companies. While both Mr. Neidorff and Ms. London served as CEO during 2022, Ms. London was our CEO on December 31, 2022, the date for which we have chosen to identify the median employee and annualize our CEO's compensation. Ms. London’s total compensation for the year ended December 31, 2022 of $13,393,942 reflects annualized amounts, as applicable, consistent with those reported in the Summary Compensation Table as if she had been CEO for the full year, plus $10,000 of the Company-paid portion of Ms. London’s medical plan premiums. The annual total compensation for the median employee for the year ending December 31, 2022 was $78,347, inclusive of the Company-paid portion of the employee’s medical plan premiums. Ms. London’s annual total compensation was 171 times that of our median employee’s pay. We last determined the median employee on December 31, 2021 by examining the total cash compensation (i.e. base wages plus short-term incentive payments) for individuals, excluding our CEO, who were employed by the Company as of December 31, 2021. During this analysis, the compensation for employees hired during the year was annualized. We included all employees, whether employed on a full-time or part-time basis, except for employees which were excluded under the de minimis exemption (1,500 in the United Kingdom), approximately 9,000 employees of our United Kingdom affiliate which we recently acquired, and employees who have anomalous pay characteristics that could significantly distort the pay ratio. This resulted in 64,825 employees being included in our median employee calculation. Notwithstanding a number of divestitures and acquisitions during 2022, there has been no significant overall change in the Company's employee population or employee compensation arrangements, and using the median employee determined in 2021 will not significantly affect the pay ratio disclosure. However, as the median employee was no longer employed with the Company, we used another employee whose compensation was substantially similar to the original median employee. After identifying the median employee, we calculated annual total compensation of the employee using the same methodology used for our NEOs within the Summary Compensation Table of this proxy statement, plus company-paid medical plan premiums capped at $10,000. Proposal 3 – Advisory Vote on How Frequent We Should Provide our Stockholders with a Say-on-Pay Vote 119 3 PROPOSAL Advisory Vote on How Frequently We Should Provide our Stockholders with a Say-on-Pay Vote Stockholders also have the opportunity at the Annual Meeting to cast a non-binding advisory vote on how frequently the Company should provide its stockholders with a Say-on-Pay vote (such as that provided above in Proposal Three). By voting on this proposal, stockholders may indicate whether they would prefer having a Say-on-Pay vote every one, two or three years, or they may abstain. The Company currently provides its stockholders a Say-on-Pay vote every year. The Board is recommending that the Company continue taking an annual Say-on-Pay vote because the Board believes this offers the highest level of accountability to our stockholders and provides the Compensation Committee with more timely, direct communication about our stockholders’ views of the Company’s compensation practices. The incremental cost of holding the Say-on-Pay vote annually is considered to be minimal. The frequency of the Say-on-Pay vote on executive compensation that receives the most votes will be considered the frequency recommended by the stockholders. While this advisory vote on the frequency of the Say-on-Pay vote is non- binding, the Board and the Compensation and Talent Committee will take into account the outcome of the frequency vote when establishing its frequency policy. The Board recommends that stockholders vote for “ANNUAL” Say-on-Pay votes. 120 Centene Corporation 4 PROPOSAL Ratification of Appointment of Independent Registered Public Accounting Firm KPMG LLP audited our financial statements for the fiscal year ended December 31, 2022. The Audit and Compliance Committee is directly responsible for the appointment, compensation, retention and oversight of the independent external audit firm retained to audit our financial statements. The Audit and Compliance Committee has appointed KPMG LLP to serve as our independent registered public accounting firm for the current fiscal year, and we are asking stockholders to ratify this appointment. KPMG LLP has been retained as our external auditor continuously since 2005. Stockholder ratification of this selection is not required by our By-laws or other applicable legal requirements. Our Board of Directors is, however, submitting the selection of KPMG LLP to stockholders for ratification as a matter of good corporate practice. In the event that stockholders fail to ratify the selection, the Audit and Compliance Committee will consider whether or not to retain that firm. Even if the selection is ratified, the Audit and Compliance Committee, in its discretion, may direct the appointment of a different independent registered public accounting firm at any time during the year if the Audit and Compliance Committee believes that a change would be in the best interests of the Company and our stockholders. We expect that representatives of KPMG LLP will be present at our Annual Meeting of Stockholders to answer appropriate questions. They will have the opportunity to make a statement if they desire to do so. The affirmative vote of the holders of a majority of the votes cast at the meeting is being sought to ratify the selection of KPMG LLP as our independent registered public accounting firm for the current fiscal year. The Audit and Compliance Committee believes the continued retention of KPMG LLP to serve as our independent registered public accounting firm is in the best interests of the Company and our stockholders. The Board recommends that stockholders vote "FOR" the ratification of the selection of KPMG LLP to serve as our independent registered public accounting firm for the fiscal year ending December 31, 2023. Independent Registered Public Accounting Firm Fees & Services The following table discloses the aggregate fees for services related to 2022 and 2021 by KPMG LLP, our independent registered public accounting firm ($ in thousands): Audit Fees Audit-Related Fees Tax Fees All Other Fees KPMG 2022 2021 $15,655 $15,512 1,535 2,538 55 — 298 — Audit-related fees in 2022 and 2021 consist primarily of fees for operational control reviews. Tax fees included in the table above relate to tax planning associated with the corporate headquarters development project. 2021 also includes fees associated with international tax matters. Proposal 4 – Ratification of Appointment of Independent Registered Public Accounting Firm 121 The Audit and Compliance Committee is responsible for the audit fee negotiations associated with our retention of KPMG LLP. When assessing services rendered by our auditor and evaluating the quality of their work, the Audit and Compliance Committee considers a variety of factors, including: independence, insight provided to the Audit and Compliance Committee, ability to meet deadlines and respond to issues, management feedback, and relative costs of services. In order to ensure continuing auditor independence, the Audit and Compliance Committee periodically considers whether there should be a regular rotation of the independent audit firm. The Audit and Compliance Committee ensures that the mandated rotation of KPMG LLP’s personnel occurs routinely and is directly involved in the selection of KPMG LLP’s lead engagement partner. Audit and Non-Audit Services Pre-Approval Policy The Audit and Compliance Committee has adopted an Audit and Non-Audit Services Pre-Approval Policy that is designed to assure that the services performed for us by our independent registered public accounting firm do not impair its independence from the Company. This policy sets forth guidelines and procedures the Audit and Compliance Committee follows when retaining an independent registered public accounting firm to perform audit, audit-related, tax and other services. The policy provides detailed descriptions of the types of services that may be provided under these four categories and also sets forth a list of services that our independent registered public accounting firm may not perform for us. Prior to engagement, the Audit and Compliance Committee pre-approves the services and fees of the independent registered public accounting firm within each of the above categories. During the year, it may become necessary to engage the independent registered public accounting firm for additional services not previously contemplated as part of the engagement. In those instances, the Audit and Non-Audit Services Pre-Approval Policy requires that the Audit and Compliance Committee specifically approve the services prior to the independent registered public accounting firm’s commencement of those additional services. Under the Audit and Non-Audit Services Pre-Approval Policy, the Audit and Compliance Committee has delegated the ability to pre-approve audit and non-audit services to the Audit and Compliance Committee chairman, provided the chairman reports any pre-approval decision to the Audit and Compliance Committee at its next scheduled meeting. The policy does not provide for a de minimis exception to the pre-approval requirements. Accordingly, all of the 2022 and 2021 fees described above were pre-approved by the Audit and Compliance Committee in accordance with the Audit and Non-Audit Services Pre-Approval Policy. Audit and Compliance Committee Report The Audit and Compliance Committee operates under a written charter adopted by the Board of Directors. The charter outlines the Audit and Compliance Committee’s duties and responsibilities. The Audit and Compliance Committee reviews the charter annually and works with the Board to amend the charter, as necessary, based on the Audit and Compliance Committee’s evolving responsibilities. The Audit and Compliance Committee charter is available on the Company’s website at investors.centene.com/corporate-governance. The Audit and Compliance Committee consists of five non-employee directors. Each member of the Audit and Compliance Committee is an independent director under the SEC rules for audit committees, financially literate and each of Jessica L. Blume, Christopher J. Coughlin, Wayne S. DeVeydt and William L. Trubeck is an “audit committee financial expert” under SEC rules. The Audit and Compliance Committee assists the Board in its oversight of the integrity of the Company’s financial statements, the Company’s compliance with legal and regulatory requirements, the qualifications and independence of the Company’s independent auditor, and the performance of the Company’s internal audit function and independent registered public accountant. Specifically, the Audit and Compliance Committee has responsibility for providing independent, objective oversight of the accounting and financial reporting process of the Company. These responsibilities include: • appointing, evaluating, and retaining the independent registered public accounting firm, which reports directly to the Audit and Compliance Committee; • • • reviewing and discussing with the auditing firm, and recommending that the Board include, the audited financial statements in the Company’s Annual Report on Form 10-K; reviewing the Company’s other financial disclosures; and assisting the Board in its oversight of the Company’s internal control over financial reporting, disclosure controls and procedures, code of business ethics and conduct and the performance of the Company’s internal audit function. 122 Centene Corporation Management is responsible for the preparation of the Company’s financial statements and the overall reporting process, for maintaining adequate internal control over financial reporting and, with the assistance of the Company’s internal auditors, for assessing the effectiveness of the Company’s internal control over financial reporting. The Company’s independent registered public accounting firm is responsible for performing an independent audit of the Company’s financial statements in accordance with the standards of the Public Company Accounting Oversight Board (the PCAOB), expressing an opinion as to the conformity of the financial statements with generally accepted accounting principles in the United States of America, and auditing management’s assessment of the effectiveness of internal control over financial reporting. KPMG LLP has served as the Company’s independent registered public accounting firm since 2005. Management represented to the Audit and Compliance Committee that the financial statements were prepared in accordance with generally accepted accounting principles and that there were no material weaknesses in its internal control over financial reporting. The Audit and Compliance Committee met and held discussions with management and KPMG LLP to review and discuss the financial statements and the Company’s internal control over financial reporting. The Audit and Compliance Committee has also discussed with KPMG LLP the firm’s judgments as to the quality and the acceptability of the Company’s financial reporting and such other matters as are required to be discussed by the applicable requirements of the PCAOB and the SEC. KPMG LLP also provided the Audit and Compliance Committee with the written disclosures and the letter required by applicable requirements of the PCAOB regarding the independent accountant’s communications with the Audit and Compliance Committee concerning independence. The Audit and Compliance Committee has discussed with KPMG LLP their independence with respect to the Company, including a review of audit and non-audit fees and services and concluded that KPMG LLP is independent. In fulfilling its oversight responsibilities for reviewing the services performed by KPMG LLP, the Audit and Compliance Committee has the sole authority to select, evaluate and replace the outside auditors. The Audit and Compliance Committee discusses the overall scope of the annual audit, the proposed audit fee, and annually evaluates the qualifications, performance and independence of KPMG LLP as independent registered public accountants and the performance of its lead audit partner. The Audit and Compliance Committee meets regularly with the internal auditors and independent registered public accounting firm, with and without management present, to discuss the results of their respective examinations, the evaluation of the Company’s internal control over financial reporting and the overall quality of the Company’s accounting. Based upon the review and discussions with the Company’s management and KPMG LLP referred to above, and its review of the representations and information provided by management and KPMG LLP, the Audit and Compliance Committee recommended to the Board that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, for filing with the SEC. The Audit and Compliance Committee also reappointed KPMG LLP to serve as the Company’s independent registered public accounting firm for 2023. AUDIT AND COMPLIANCE COMMITTEE William L. Trubeck, Chair Orlando Ayala Jessica L. Blume Christopher J. Coughlin Wayne S. DeVeydt Proposal 5 – Stockholder Proposal for Shareholder Ratification of Termination Pay 123 5 PROPOSAL Stockholder Proposal for Shareholder Ratification of Termination Pay In October 2022, the Company received correspondence from a stockholder, John Chevedden, 2215 Nelson Avenue, No. 205, Redondo Beach, CA 90278, beneficial owner of at least $2,000 in market value, of Centene common stock since July 1, 2019 and for the requisite period, who intends to propose the following resolution on shareholder ratification of termination pay at the annual meeting. Stockholder Statement Regarding Proposal for Shareholder Ratification of Termination Pay Proposal Five — Shareholder Ratification of Termination Pay Shareholders request that the Board seek shareholder approval of any senior manager’s new or renewed pay package that provides for severance or termination payments with an estimated value exceeding 2.99 times the sum of the executive’s base salary plus target short-term bonus. “Severance or termination payments” include cash, equity or other pay that is paid out or vests due to a senior executive’s termination for any reason. Payments include those provided under employment agreements, severance plans, and change- in-control clauses in long-term equity plans, but not life insurance, pension benefits, or deferred pay earned and vested prior to termination. “Estimated total value” includes: lump-sum payments; payments offsetting tax liabilities, perquisites or benefits not vested under a plan generally available to management employees, post-employment consulting fees or office expense and equity awards if vesting is accelerated, or a performance condition waived, due to termination. The Board shall retain the option to seek shareholder approval after material terms are agreed upon. Generous performance-based pay can sometimes be justified but shareholder ratification of “golden parachute” severance packages with a total cost exceeding 2.99 times base salary plus target short-term bonus better aligns management pay with shareholder interests. For instance at one company, that does not have this policy, if the CEO is terminated he could receive $44 million in termination pay — over 10 times his base salary plus short-term bonus. In the event of a change in control, the same person could receive a whopping $124 million in accelerated equity payouts even if he remained employed. It is especially important that this type situation be avoided at Centene since management pay was resoundly rejected by 66% of shares in 2022. Plus Mr. Orlando Ayala was rejected by 59 million shares and Mr. James Dallas was rejected by 102 million shares. This is all worse in the case of Mr. Dallas since he was touted under Centene’s Recent Board Refreshment notice. This proposal topic received between 51% and 65% support at: AbbVie (ABBV) FedEx (FDX) Spirit AeroSystems (SPR) Alaska Air (ALK) Fiserv (FISV) Please vote yes: Shareholder Ratification of Termination Pay — Proposal Five 124 Centene Corporation Board of Directors’ Statement in Opposition to Proposal Five The Board has carefully considered this proposal and has concluded that its adoption is not in the best interests of the Company’s stockholders. Accordingly, the Board unanimously recommends a vote AGAINST this proposal for the reasons outlined below. • Centene has an existing policy limiting cash severance under future plans and agreements. • • • Existing plans and agreements are consistent with market norms and provide for a maximum cash severance amount that is equal to or less than 2.99 times the sum of an Executive Officer's Base Salary and Annual Bonus. The proposal would restrict the use of equity incentive awards, creating misalignment between executives and stockholders during change in control transactions and increasing risks to executive retention and deal certainty The proposal would discourage the use of long-term equity awards as an important part of Centene’s executive compensation programs WE HAVE AN EXISTING POLICY REQUIRING STOCKHOLDER APPROVAL OF ANY CASH SEVERANCE PAYMENT TO AN EXECUTIVE OFFICER IN EXCESS OF 2.99 TIMES THE SUM OF THE EXECUTIVE OFFICER’S BASE SALARY AND ANNUAL BONUS Centene's Cash Severance Policy already provides that the Company will not enter into any new employment agreement or severance agreement with any Executive Officer of the Company, or establish any new severance plan or policy covering any Executive Officer of the Company, that provides for cash severance benefits that exceed 2.99 times the sum of the Executive Officer’s Base Salary plus the greater of Target Bonus or the average of the Executive Officer’s two most recent annual bonuses, without seeking stockholder ratification of such agreement, plan or policy. OUR EXISTING EMPLOYMENT AGREEMENTS AND EXECUTIVE SEVERANCE PLAN LIMIT CASH SEVERANCE TO AN AMOUNT EQUAL TO OR LESS THAN 2.99 TIMES THE SUM OF THE EXECUTIVE OFFICER'S BASE SALARY AND ANNUAL BONUS. Pursuant to the Executive Severance Plan, if an executive experiences a qualifying termination of employment in connection with a change in control, the executive receives a lump sum cash payment equal to the sum of (1) an amount equal to 24 months of salary, (b) the average of the executive’s last two annual bonuses multiplied by two, and (c) a prorated annual bonus for the year in which the termination occurs. If an executive experiences a qualifying termination of employment absent a change in control, under our Executive Severance Plan, the executive will receive 12 months of salary continuation and a prorated annual bonus for the year in which the termination occurs. Our executive employment agreements are generally consistent with the above except that our CEO receives, in the case of a qualifying change in control termination, 2.99x the sum of her salary and the greater of her target annual bonus then in effect or the average of the two most recent annual bonuses earned and, in the event of a qualifying termination absent a change in control, two times the sum of her base salary and the greater of her target annual bonus then in effect or the average of the two most recent annual bonuses earned. THE STOCKHOLDER PROPOSAL, IF IMPLEMENTED, WOULD CREATE MISALIGNMENT BETWEEN OUR EXECUTIVE OFFICERS AND OUR LONG-TERM STOCKHOLDERS, INCLUDING DURING A CRITICAL TRANSACTION PROCESS, AND WOULD DISCOURAGE THE USE OF EQUITY AWARDS IN OUR EXECUTIVE COMPENSATION PROGRAM Pursuant to our Executive Severance Plan and our executive employment agreements, if an executive is involuntarily terminated without cause in connection with a change in control, outstanding equity awards will vest in full. Without the ability to accelerate vesting of the equity awards of our senior executives upon an involuntary termination following a change of control, our ability to deliver maximum stockholder value in such a transaction could be impaired. The risk of job loss following a change in control, coupled with a limit on the value that may be realized from previously granted equity awards, may present an unnecessary distraction for our senior executives and could lead them to begin seeking new employment while a transaction is being negotiated or is pending. The proposal would significantly limit our Board’s flexibility to provide reasonable assurance to our senior executives that they could realize the full expected value of their previously granted equity awards even if a change-of-control transaction were completed. In addition, requiring stockholder approval of severance arrangements including acceleration of equity awards on an involuntary termination could place us in Proposal 5 – Stockholder Proposal for Shareholder Ratification of Termination Pay 125 a competitive disadvantage by limiting the Company’s ability to attract and retain key executive talent in a highly competitive market, thereby, ultimately negatively impacting the Company’s long-term success and stockholders’ long-term interest. SUMMARY Centene’s Executive Severance Plan and form of executive employment agreement are reviewed from time-to-time for compliance and alignment with market best practices. Further, the Company reviews all executive level terminations and ensures that severance, where provided, is appropriate and consistent with the approved arrangements, the Company’s objectives, and market practices. We believe that the Company, through the Committee, should have the responsibility and flexibility to set the guidelines and criteria for all plans within Centene’s executive compensation program, including its severance practices. The stockholder proposal, if implemented, would create a misalignment of the interest of our executive officers with those of our stockholders, jeopardize our ability to effectively execute any potential change-in-control transaction that may otherwise maximize stockholder value, impair our ability to incorporate long-term equity awards in our executive compensation program, and prevent us from effectively recruiting, motivating and retaining executive officers. For the reasons discussed above, adoption of this proposal is unnecessary and is not in the best interest of Centene and its stockholders. The Board recommends that stockholders vote “AGAINST” the stockholder proposal regarding shareholder ratification of termination pay. 126 Centene Corporation 6 PROPOSAL Stockholder Proposal for Maternal Morbidity Reduction Metrics in Executive Compensation In November 2022, the Company received correspondence from a stockholder, the New York Office of the Comptroller, 110 State Street, Albany, New York 12236, a beneficial owner of at least $25,000 in market value of Centene's common stock since November 9, 2021 and for the requisite period, regarding a proposal on maternal morbidity reduction metrics in executive compensation it intends to propose at the annual meeting as described below. Resolved: Shareholders of Centene Corporation (Centene) request that the Board of Directors examine and report to shareholders, at reasonable cost and omitting proprietary information, describing if, and how it plans to introduce objective data driven maternal morbidity reduction metrics into the performance measures of senior executives under Centene’s incentive compensation plans. “Maternal morbidity metrics” is defined as (1) the rate of major maternal morbidity of Centene’s members and (2) progress made toward eliminating major maternal morbidity and mortality disparities among racial and ethnic groups. Supporting Statement: As a managed care provider, Centene stands to widen its margins sustainably and grow its business responsibly by improving the health outcomes of its members. When its members’ health improves, medical costs go down. Centene provides its Smart Start for Your Baby program for pregnant members. By helping to lower the risks of premature births and major maternal complications, the program is working to improve maternal and child health outcomes among Centene’s members. This focus on maternal and child health outcomes can create sustainable success for the company In June 2022, the White House released a report examining the state of maternal health across the country. The report, based on examination of trends in pregnancy and childbirth complications, concluded that the nation faces “a maternal health crisis”: • The United States ranks last among developed countries in maternal health care. • • • A Blue Cross Blue Shield study of current trends related to serious complications during labor and delivery (known as “maternal morbidity”) rates increased for all women between the years 2018-2020. Black mothers are twice as likely to experience severe maternal morbidities (SMM) as white mothers. Black mothers are also more than twice as likely to die in childbirth than white mothers. A study based on New York City hospital data found wide disparities in maternal morbidity between races. Women who experience a SMM event are far more likely to be readmitted to a hospital during the postpartum period than women who do not experience one. A recent study published in Women’s Health Reports examining costs found that the total mean per-patient costs of care for women with SMM is 177% higher than for women without SMM. Centene is the largest Medicaid managed care organization in the country. Membership in Medicaid is associated with significantly higher incidence of severe maternal health outcomes compared with privately insured women. Centene can contribute to reducing overall disparities in the United States by undertaking renewed efforts to reduce SMM disparities at Centene among its own members. Narrowing these disparities by improving outcomes may lead to significant cost savings for our company. This type of metric is not unprecedented. Anthem’s May 2022 ESG report notes that a portion of its “executives’ annual incentive compensation is based on the improvement in maternity health outcomes and reduction of pre-term births for black communities in Indiana.” Proposal 5 – Stockholder Proposal for Shareholder Ratification of Termination Pay 127 Board of Directors’ Statement in Opposition to Proposal Six The Board has carefully considered this proposal and has concluded that its adoption is not in the best interests of the Company's stockholders. Accordingly, the Board unanimously recommends a vote AGAINST this proposal for the reasons outlined below. • The Company has comprehensive clinical programs designed to improve the quality of care for our members. • Our 2022 and 2023 short term incentive bonus plans include performance criteria based on quality metrics which relate to prenatal and postnatal care. THE COMPANY HAS COMPREHENSIVE CLINICAL PROGRAMS DESIGNED TO IMPROVE THE QUALITY OF CARE FOR OUR MEMBERS. Centene’s mission is to transform the health of the community, one person at a time. As a result, the Company is focused on the quality of healthcare each of our members receive. Improving quality is a key component of our Company’s strategy, across all of its lines of business, for each of its members. Specifically, the Company has a comprehensive program designed to improve maternal health outcomes, called Start Smart for Your Baby. Start Smart for Your Baby’s goal is to extend the gestational period and reduce the risk of pregnancy complications, premature delivery, low birth weight and infant disease. The program uses a predictive model to identify high-risk pregnancies, allowing clinically informed, culturally sensitive health education materials and wellness programs to be provided to these members. The Company has also launched a doula pilot program that complements the Start Smart for Your Baby program and is focused on black birthing parents to address the adverse maternal health outcomes in this population in New York. In Georgia, the Company has partnered with Quilted to provide clinic-based services in areas of without access to obstetricians to improve outcome metrics for black mothers and babies. In Mississippi, the Company has partnered with Pomelo to provide virtual primary and maternity care to mothers in rural areas. In demonstration of the importance this has to Centene, on January 1, 2023, Centene hired Alice Chen, MD, MPH as our Chief Health Officer. Dr. Chen is responsible for Centene's strategies, policies, and programs in support of improving population health for Centene's more than 26 million members. OUR 2022 AND 2023 SHORT TERM INCENTIVE BONUS PLAN INCLUDE PERFORMANCE CRITERIA BASED ON QUALITY METRICS WHICH RELATE TO PRENATAL AND POSTNATAL CARE. As described below in the Section titled “Compensation Discussion and Analysis,” the Company has a pay for performance compensation structure. Starting in 2022, the Company began including quality as a component of the short term incentive bonus plan, which has been continued in 2023. This holds the Company’s employees, including our CEO, accountable to the quality performance metrics that tie directly to the Company’s Medicaid and Medicare contracts. Our quality metrics include measures related to Medicare Star ratings and 15 Medicaid Priority HEDIS measures, reflecting the most common measures across our Medicaid programs. Two of these measures relate to metrics on prenatal and postnatal care. The Healthcare Effectiveness Data and Information Set (HEDIS) is the most widely used performance improvement tool in government healthcare programs. The National Committee for Quality Assurance (NCQA), the nation’s leading quality accreditation program, collects HEDIS data on behalf of Centers for Medicare & Medicaid Services (CMS) and on behalf of state agencies. NCQA then uses this data collection in NCQA’s Quality Compass tool for comparative health plan performance analyses. SUMMARY Centene has a robust quality improvement program, and objective quality data has already been included in its performance measures under Centene’s incentive compensation plans for senior executives. We believe the criteria we use aligns with our government customers that design the Medicaid and Medicare programs, as well as how each of those programs measure their quality performance. The Board recommends that stockholders vote “AGAINST” the stockholder proposal. 128 Centene Corporation Security Ownership of Certain Beneficial Owners and Management Five Percent Beneficial Owners of Common Stock The following table sets forth the beneficial ownership of our common stock as of March 13, 2023, by (a) each person known to us to be the beneficial owner of more than five percent of the Company’s common stock, (b) each of our NEOs and directors, including our director nominees, and (c) all directors and executive officers as a group.

Under rules adopted by the U.S. Securities and Exchange Commission (the “SEC”), we provide access to our proxy materials on the Internet. Accordingly, we are sending a Notice of Internet Availability of Proxy Materials (the “Availability Notice”) to some of our stockholders. If you received an Availability Notice by mail, you will not receive a printed copy of the proxy materials unless you request one. The Availability Notice will tell you how to access and review the proxy materials on the Internet at www.proxyvote.com. The Availability Notice also tells you how to access your proxy card to vote on the Internet.

Is there a minimum number of shares that must be represented in person or by proxy to hold the Annual Meeting? Yes. A quorum is the minimum number of shares that must be present to conduct business at the Annual Meeting. The quorum requirement is the number of shares that represent a majority of the outstanding shares of the Company as of the record date. Shares necessary to meet the quorum requirement may be present in person or represented by proxy. There were 550,700,443 shares of our common stock issued and outstanding on the record date. Therefore, at least 275,350,222 shares of our common stock must be present in person or represented by proxy at the Annual Meeting to satisfy the quorum requirement. Your shares will be counted to determine whether there is a quorum if you submit a valid proxy card or voting instruction form, give proper instructions over the telephone or on the Internet, or attend the Annual Meeting in person. Pursuant to Delaware law, proxies received but marked as abstentions and broker non-votes (which are discussed in Question 16 below) are counted as present for purposes of determining a quorum. 10. Who can vote on matters that will be presented at the Annual Meeting? You can vote if you were a stockholder of the Company at the close of business on the record date of March 13, 2023 11. What is the difference between a registered stockholder and a beneficial owner? Many Centene stockholders hold their shares through a stockbroker, bank or other nominee rather than directly in their own names. As summarized below, there are some distinctions between shares held of record and those owned beneficially. • Registered stockholder: If your shares are registered directly in your name with the Company’s transfer agent, Broadridge Corporate Issuer Solutions, Inc., you are considered, with respect to those shares, the “stockholder of record” or a “registered stockholder,” and these proxy materials are being sent directly to you by the Company. As the stockholder of record, you have the right to deliver your voting proxy directly to the Company or to vote in person at the Annual Meeting. • Beneficial owner: If your shares are held in a stock brokerage account or by a bank, trustee or other nominee, you are considered the “beneficial owner” of those shares, and these proxy materials are being forwarded to you by your broker, bank or other holder of record who is considered, with respect to those shares, the stockholder of record. As the beneficial owner you have the right to direct your broker, bank or other holder of record on how to vote your shares and you are invited to attend the Annual Meeting. Your broker, bank, trustee or nominee is obligated to provide you with a voting instruction form for you to use. 12. How many votes am I entitled to per share? Each share of common stock outstanding on the record date is entitled to one vote on each matter properly presented at the Annual Meeting. Stockholders do not have a right to cumulate their votes. 13. Who will count the vote? Broadridge Investor Communications Solutions, Inc. was appointed by our Board to tabulate the vote and act as Inspector of Election. Information about Broadridge Investor Communications Solutions, Inc. is available at www.broadridge.com. 14. How do I cast my vote? Registered stockholders: There are four ways you can cast your vote: • Vote on the Internet at www.proxyvote.com using the control number provided to you by 11:59 PM. Eastern Time on May 9, 2023; • • Vote by telephone at 1-800-690-6903 using the control number provided to you by 11:59 PM. Eastern Time on May 9, 2023; If you received a proxy card, complete and properly sign, date and return it in the postage paid envelope provided. If voting by mail, please allow sufficient time for the postal service to deliver your proxy card before the Annual Meeting; or • Attend the Annual Meeting and deliver your completed proxy card or complete a ballot in person. Commonly Asked Questions and Answers About the Annual Meeting 133 Beneficial owners: Your proxy materials should include a voting instruction form from the institution holding your shares. There are up to four ways you can cast your vote: • Vote on the Internet at www.proxyvote.com using the control number provided to you by the institution holding your shares by 11:59 PM. Eastern Time on May 9, 2023; • • • • Vote by telephone using the telephone number and the control number provided to you (note: the availability of telephone voting will depend upon the institution’s voting processes); Complete and properly sign, date and return a voting instruction form from the institution holding your shares. Please allow sufficient time for your instructions to be received by the institution before the Annual Meeting; or Obtain a legal proxy from the institution holding your shares to vote in person at the Annual Meeting. Please contact the institution holding your shares for additional information, including its deadline for voting. 15. What is the voting requirement to approve each of the proposals? How do abstentions and broker non-votes affect the vote outcome? Proposal 1: Each director will be elected by a majority of votes cast, which means a majority of the votes cast “for” or “against” the particular director, whether in person or by proxy. Proposals 2, 4, 5 and 6: Proposals 2, 4, 5 and 6 will pass with the votes of a majority of votes cast, which means a majority of the votes cast “for” or “against” the proposal, whether in person or by proxy. Proposal 3: Under Proposal 3, stockholders have the choice of recommending that the Company provide a Say-on-Pay vote every 1, 2 or 3 years. The Company will consider the frequency that receives the most votes to be the frequency selected by the stockholders. A broker non-vote (a broker non-vote is explained in the answer to Question 16) on a proposal is considered a share not entitled to vote on that proposal and is not a vote cast. Accordingly, a broker non-vote will have no effect on the vote outcome of any proposal. Abstentions are considered shares entitled to vote on a proposal but are not considered as having been cast “for” or “against” a proposal. Therefore, abstentions will have no effect on the vote outcome of any proposal. Discretionary voting by brokers will be permitted by the New York Stock Exchange only in connection with Proposal 2. Discretionary voting is explained in the answer to Question 16. 16. What if I return my proxy card or voting instruction form but do not provide voting instructions? Registered stockholders: If you are a registered stockholder and you return your signed proxy card, your shares will be voted as you designate on the proxy card. If you do not return your voted proxy card, vote by phone or the Internet, or if you submit your proxy card with an unclear voting designation, your shares will not be voted. If you return your signed proxy card and do not provide a voting designation, your shares will be voted FOR the election of all director nominees listed in Proposal 1; FOR Proposals 2 and 4 and for ANNUAL Say-on-Pay votes under Proposal 3; and AGAINST Proposals 5 and 6. The proxy holders will vote in their discretion as to any other matters that arise at the Annual Meeting. Beneficial owners: In limited instances, your shares may be voted if they are held in the name of a broker, bank or other intermediary, even if you do not provide the holder with voting instructions. This is called “discretionary voting.” Brokerage firms and banks generally have the authority, under NYSE rules, to vote shares on certain “routine” matters for which their customers do not provide voting instructions. Of the six proposals scheduled to be presented at the Annual Meeting, only Proposal 2, Ratification of the Appointment of Independent Registered Public Accounting Firm, is considered a routine matter under the NYSE’s rules. Proposals 1, 3, 4, 5 and 6 and any other matter that may be presented at the Annual Meeting, are not considered routine. When a proposal is not a routine matter and the institution holding the shares has not received voting instructions from the beneficial owner of the shares with respect to that proposal, the institution cannot vote the shares on that proposal. This is called a “broker non-vote.” In tabulating the voting result for any particular proposal, shares represented at the Annual Meeting that constitute broker non-votes will not be included in vote totals. As a result, they will have no effect on the outcome of any vote. 134 Centene Corporation 17. Can I change my mind after I submit my proxy? Yes; if you vote by proxy, you may revoke that proxy by: • voting again on the Internet or by telephone prior to the applicable deadline for the votes to be tabulated at the Annual Meeting; • • signing another proxy card with a later date and mailing it, provided it is received prior to the Annual Meeting; or attending the Annual Meeting in person and delivering your proxy or casting a ballot. If you are a beneficial owner of our stock, you must obtain a legal proxy from the institution holding your shares to vote in person at the Annual Meeting. 18. Where can I find the voting results of the Annual Meeting? We intend to announce preliminary voting results at the Annual Meeting and publish voting results on a Current Report on Form 8-K within four business days after the conclusion of the Annual Meeting. The Form 8-K will be accessible at the SEC’s website at www.sec.gov or on our website at www.centene.com. 20. What if I have additional questions that are not addressed here? You may call Investor Relations at (212) 549-1306, e-mail Investor Relations at investors@centene.com or call the Office of the Secretary at (314) 725-4477. Other Matters 135 Other Matters Committee Reports The information contained in the Compensation and Talent Committee Report and the Audit and Compliance Committee Report does not constitute soliciting material and should not be deemed filed or incorporated by reference into any other of our filings under the Securities Act of 1933 or the Exchange Act, except to the extent the filing specifically incorporates such information by reference therein. Proxy Solicitation Costs This proxy solicitation is sent on behalf of our Board, and all costs and expenses associated with soliciting proxies will be borne by the Company. In addition to the use of the mails, our directors, executive officers and our associates by personal interview, telephone or telegram may solicit proxies. Such directors, executive officers and associates will not be additionally compensated for such solicitation but may be reimbursed for out-of-pocket expenses incurred in connection therewith. Arrangements will also be made with custodians, nominees and fiduciaries for the forwarding of solicitation material to the beneficial owners of our common stock held of record by such persons, and we will reimburse such custodians, nominees and fiduciaries for their reasonable out-of-pocket expenses incurred in connection therewith. We have retained Saratoga Proxy Consulting, LLC, a proxy soliciting firm, to assist with the solicitation of proxies for a fee of $12,500 plus fees for any retail stockholder outreach services and reimbursement for out-of-pocket expenses. 136 Centene Corporation Stockholder Proposals Stockholder Proposals for Inclusion in our 2024 Proxy Statement.

Please be aware that merely submitting a proposal to us is not a guarantee that it will either be included in our 2024 proxy statement or considered at our 2024 annual meeting of stockholders. Multiple Stockholders Having the Same Address We have adopted a process called “householding” for mailing proxy materials in order to reduce costs. Householding means that stockholders who share the same last name and address will receive only one copy of our 2022 Annual Report on Form 10-K and this proxy statement (collectively, the “proxy materials”) unless we receive contrary instructions. For those stockholders receiving our Notice of Internet Availability of Proxy Materials (“Availability Notice”), we will provide a separate Availability Notice for each stockholder. For those households receiving copies of our Annual Reports on Form 10-K and proxy statements, we will continue to mail a proxy card to each stockholder of record. If you prefer to receive multiple copies of the proxy materials at the same address, additional copies will be provided to you promptly upon request. If you hold your shares in street name or are a registered holder, you should direct your request to Broadridge, Householding Department, 51 Mercedes Way, Edgewood, NY 11717, telephone number (800) 542-1061. You may also request copies of our proxy materials or notify us that you wish to receive a separate copy of these documents for each stockholder, or a single copy for each address, by writing to Investor Relations Department, Centene Corporation, 7700 Forsyth Boulevard, St. Louis, Missouri 63105, or by calling (314) 725-4477.

The information contained in any website or report referenced in this proxy statement is not incorporated by reference into, and does not form a part of, this proxy statement. Forward-Looking Statements All statements, other than statements of current or historical fact, contained in this proxy statement 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 (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 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 proxy statement are based on information available to us on the date hereof. Except as may be otherwise required by law, we undertake no obligation to update or revise the forward-looking statements included in this proxy statement, whether as a result of new information, future events, or otherwise, after the date hereof. 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; our ability to accurately predict and effectively manage health benefits and other operating expenses and reserves, including fluctuations in medical utilization rates; competition, including our ability to reprocure our contracts and grow organically; the timing and extent of benefits from our value creation strategy, including the possibility that the benefits received may be lower than expected, may not occur, or will not be realized within the expected time periods; disruption, unexpected costs, or similar risks from business transactions, including acquisitions, divestitures, and changes in our relationships with third parties; impairments to real estate, investments, goodwill, and intangible assets; the risk that the election of new directors, changes in senior management, and any inability to retain key personnel may create uncertainty or negatively impact our ability to execute quickly and effectively; membership and revenue declines or unexpected trends; rate cuts or other payment reductions or delays by governmental payors and other risks and uncertainties affecting our government businesses; changes in healthcare practices, new technologies, and advances in medicine; increased healthcare costs; inflation; changes in economic, political, or market conditions; changes in federal or state laws or regulations, including changes with respect to income tax reform or government healthcare programs as well as changes with respect to the Patient Protection and Affordable Care Act and the Health Care and Education Affordability Reconciliation Act (collectively referred to 138 Centene Corporation as the ACA) and any regulations enacted thereunder; tax matters; disasters or major epidemics; changes in expected contract start dates; 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; challenges to our contract awards; cyber-attacks or other privacy or data security incidents; the exertion of management's time and our resources, and other expenses incurred and business changes required in connection with complying with the undertakings in connection with any regulatory, governmental, or third party consents or approvals for acquisitions or dispositions; any changes in expected closing dates, estimated purchase price, and accretion for acquisitions or dispositions; restrictions and limitations in connection with our indebtedness; a downgrade of the credit rating of our indebtedness; the availability of debt and equity financing on terms that are favorable to us; foreign currency fluctuations; and risks and uncertainties discussed in the reports that Centene has filed with the Securities and Exchange Commission. 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, 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. Appendix A - Reconciliation of Non-GAAP Measures 139 Appendix A - Reconciliation of Non-GAAP Measures This proxy statement includes certain non-GAAP financial measures 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 to allow management to focus on period-to-period changes in the Company’s core business operations. Therefore, the Company believes that this information is meaningful in addition to the presented GAAP financial information. The presentation of this additional non-GAAP financial information is not intended to be considered in isolation or as a substitute for related GAAP financial information. Specifically, the Company believes the presentation of non-GAAP financial information that excludes amortization of acquired intangible assets, acquisition related expenses, as well as other items, allows investors to develop a more meaningful understanding of the Company’s performance over time. The tables and discussion below provide reconciliations of non-GAAP items.
