This EXECUTIVE EMPLOYMENT AGREEMENT (“Agreement”) is made as of April 27, 2022, by and between Centene Corporation (together with its successors and assigns, the “Company”), and Sarah M. London (“Executive”).

WHEREAS, the Company desires to continue to employ Executive as the Company’s Chief Executive Officer; and

WHEREAS, the Company and Executive mutually desire to set forth and agree to certain terms of Executive’s employment.

NOW, THEREFORE, in consideration of the foregoing recitals, the mutual covenants and conditions herein, and other good and valuable consideration, the receipt and adequacy of which is hereby acknowledged, the parties hereby agree as follows:

1.Employment and Term. The Company hereby agrees to continue to employ Executive and Executive hereby accepts continued employment by the Company on the terms and conditions hereinafter set forth. Executive’s term of employment by the Company under this Agreement (the “Term”) commenced on March 21, 2022 (the “Effective Date”) and shall continue through the three-year anniversary of such date; provided, however, that the Term shall thereafter be automatically extended for unlimited additional one-year periods unless, at least ninety (90) days prior to the then-scheduled date of expiration of the Term, either (x) the Company gives written notice to Executive that it is electing not to so extend the Term or (y) Executive gives written notice to the Company that Executive is electing not to so extend the Term. Notwithstanding the foregoing, the Term may be earlier terminated in strict accordance with the provisions of Section 5 below, in which event Executive’s employment with the Company shall expire in accordance therewith.

2.Position, Duties and Responsibilities; Location.

2.1     Position and Duties. Executive shall be employed as Chief Executive Officer of the Company and shall serve as a member of the Company’s Board of Directors (the “Board”). Executive shall have, subject to the Company’s Bylaws and the direction of the Board, general overall authority and responsibility for the day-to-day management of the affairs and business of the Company and its subsidiaries, if any, and primary responsibility for the formulation, implementation and execution of strategic policies relating to the Company’s business operations, financial objectives and market growth. Executive shall have such duties, powers and authority as are commensurate with her position, including such other duties and responsibilities as are reasonably delegated to Executive, from time-to-time by the Board. Executive shall report solely and directly to the Board and, for the avoidance of doubt, shall not report to any specific member of the Board.

2.2     Exclusive Services and Efforts. Executive agrees to devote Executive’s best reasonable efforts, energies, and skill to the full discharge of the duties and responsibilities attributable to Executive’s position and, except as set forth herein, agrees to devote substantially all of Executive’s professional time and attention exclusively to the business and affairs of the Company. Notwithstanding

the foregoing, Executive may (a) serve on the boards of a reasonable number of trade associations and charitable organizations, (b) engage in charitable activities and community affairs, (c) manage Executive’s personal investments and affairs and (d) subject to prior approval by the Board (which approval shall not be unreasonably withheld), serve on up to two (2) boards of directors of unaffiliated companies, so long as such activities do not, either individually or in the aggregate, materially interfere with the proper performance of Executive’s duties and responsibilities hereunder.

3.Compensation.

3.1    Base Salary. During the Term, the Company hereby agrees to pay to Executive an annualized base salary (the “Salary”) of One Million Four Hundred Thousand Dollars ($1,400,000), less all applicable federal, state and local income and employment taxes and other required or elected withholdings and deductions, payable in equal installments on the Company’s regularly-scheduled paydays as it is earned. Executive’s Salary will be reviewed at least annually by the Compensation Committee of the Board (the “Compensation Committee”) and may be adjusted upward (in which case such increased amount shall be the “Salary” hereunder) or remain the same (but in no event shall the Salary be reduced). Notwithstanding the foregoing, the Company may reduce the Salary if such reduction is also applicable in a substantially similar manner and proportion to reductions to other senior executives of the Company generally.

3.2 Annual Bonus. For each calendar year that ends during the Term, Executive shall be entitled to receive an annual cash incentive award (the “Annual Bonus”). Executive’s target Annual Bonus shall be no less than one hundred fifty percent (150%) of Executive’s Salary. For purposes of calculating any Annual Bonus payable for 2022, Executive’s Salary shall be calculated using the following proration formula:

For each year, the Compensation Committee shall award the Annual Bonus based on an evaluation of performance and peer company compensation practices, taking into account Company and individual performance objectives. The Compensation Committee may award an Annual Bonus in excess of the target amount, and may grant a special bonus at any time. The Annual Bonus shall be paid in the calendar year following the year in which the services were performed, as soon as reasonably practicable following the Compensation Committee’s approval thereof, but in no event later than March 15 of the year following the year in which services were performed.

3.3 Long-Term Incentive Awards. Executive shall be eligible for annual grants of long-term cash and equity compensation awards at the Company’s good faith discretion, based upon the Compensation Committee’s evaluation of her performance and peer company compensation practices (each, a “Long-Term Award”). The Long-Term Awards may consist of (a) a cash-based long-term incentive awards (the “Cash Awards”) under the Company’s 2007 Long-Term Incentive Plan, as amended, or successor-plan (the “LTIP”), and (b) service-based restricted stock units, performance-based restricted stock units and performance-based stock options (the “Equity Awards”) issued under the Company’s 2012 Stock Incentive Plan, as amended, or successor plan (the “Stock Plan”). Each Cash Award shall be subject to the terms of the LTIP and an award agreement to be executed by Executive and the Company, and each Equity Award shall be subject to the terms of the Stock Plan and award agreements to be executed by Executive and the Company; provided, that the terms of such awards shall be no less favorable than provided to other senior executives of the Company generally. Executive’s annual target Long-Term Awards shall be not less than $12,500,000. The Company may reduce the target

value of the Long-Term Awards if such reduction is also applicable in a substantially similar manner and proportion to reductions to other senior executives of the Company generally.

4.Employee Benefits.

4.1    Participation in Benefit Plans. During the Term, Executive shall be entitled to participate in such health, group insurance, welfare, pension, and other employee benefit plans, programs and arrangements as are made generally available from time to time to senior executives of the Company (which shall include customary life insurance and disability plans), such participation in each case to be on terms and conditions no less favorable to Executive than to other senior executives of the Company generally.

4.2    Fringe Benefits, Perquisites and Vacations. During the Term, Executive shall be entitled to participate in all fringe benefits and perquisites made available to other senior executives of the Company, such participation to be at levels, and on terms and conditions, that are commensurate with her position and responsibilities at the Company and that are no less favorable than those applying to other senior executives of the Company. In addition, Executive shall be entitled to twenty-five (25) days’ paid vacation per calendar year (which, if not used, may be carried over from year to year).

4.3    Reimbursement of Expenses. The Company shall reimburse Executive for all reasonable business and travel expenses incurred in the performance of her job duties and the promotion of the Company’s business, promptly upon presentation of appropriate supporting documentation and otherwise in accordance with the expense reimbursement policy of the Company.

4.4    Use of Company Aircraft. Executive shall be entitled to use aircraft operated by the Company (the “Company Aircraft”), to the extent such aircraft are reasonably available, (a) for business uses related to Executive’s responsibilities with respect to the management of the Company’s operations and (b) for reasonable personal uses, subject to the Company’s priority for business purposes. The timing and amount of Executive’s use of the Company Aircraft shall be at Executive’s reasonable discretion but, in any event, shall be subject to reasonable limitations established by the Board. In no event shall Executive be permitted to use any Company Aircraft if and to the extent it would cause the Company’s ability to deduct the use, ownership or operation of any Company Aircraft as an expense or otherwise to be impaired or lost.

6.Excess Parachute Payments.

6.1    If any payment or benefit (including payments and benefits pursuant to this Agreement) that Executive would receive in connection with a Change in Control from the Company or otherwise (“Transaction Payment”) would (a) constitute a “parachute payment” within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”); and (b) the net after-tax benefit (after giving effect to all federal, state and local taxes) that Executive would receive by reducing the Transaction Payments to three times the “base amount,” as defined in Section 280G(b)(3) of the Code (the “Parachute Threshold”), is greater than the net after-tax benefit (after giving effect to all federal, state and local taxes, including any applicable excise taxes) Executive would receive if the full amount of the Transaction Payments were paid to Executive, then the Transaction Payments payable to Executive shall be reduced (but not below zero) so that the Transaction Payments due to Executive do not exceed the amount of the Parachute Threshold, reducing first any Transaction Payments under Section 5.5(a) and (b) hereof.

6.2    Unless Executive and the Company otherwise agree in writing, any determination required under this section shall be made in writing by the Company’s independent public accountants (the “Accountants”), whose determination shall be conclusive and binding upon Executive and the Company for all purposes. Subject to Section 7.4 of this Agreement, for purposes of making the calculations required by this section, the Accountants may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code. The Accountants shall provide detailed supporting calculations to the Company and Executive as requested by the Company or Executive at least thirty (30) days prior to the date the excise tax imposed by Section 4999 of the Code (including any interest, penalties or additions to tax relating thereto) is required to be paid by Executive or withheld by the Company. Executive and the Company shall furnish to the Accountants such information and documents as the Accountants may reasonably request in order to make a determination under this section. The Company shall bear all costs the Accountants may incur in connection with any calculations contemplated by this section as well as any costs incurred by Executive with the Accountants for tax planning under Sections 280G and 4999 of the Code.

7.Indemnification.

7.1    If Executive is made a party, is threatened to be made a party, or reasonably anticipates being made a party, to any Proceeding by reason of the fact that Executive is or was a director,

officer, shareholder, employee, agent, trustee, consultant or representative of the Company or any of its affiliates or is or was serving at the request of the Company or any of its affiliates, or in connection with Executive’s service hereunder as a director, officer, shareholder, employee, agent, trustee, consultant or representative of another Person, or if any Claim is made, is threatened to be made, or is reasonably anticipated to be made, that arises out of or relates to Executive’s service in any of the foregoing capacities, then Executive shall promptly be indemnified and held harmless to the fullest extent permitted or authorized by any Company Arrangement, or if greater, by applicable law, against any and all costs, expenses, liabilities and losses (including, without limitation, attorneys’ and other professional fees and charges, judgments, interest, expenses of investigation, penalties, fines, excise taxes under the Employee Retirement Income Security Act of 1974 or penalties and amounts paid or to be paid in settlement) incurred or suffered by Executive in connection therewith or in connection with seeking to enforce Executive’s rights under this Section 7.1, and such indemnification shall continue even if Executive has ceased to be a director, officer, shareholder, employee, agent, trustee, consultant or representative of the Company or other Person and shall inure to the benefit of Executive’s heirs, executors and administrators.

7.2    A directors’ and officers’ liability insurance policy (or policies) shall be kept in place, during the Term and thereafter until the sixth (6th) anniversary of the Termination Date, providing coverage to Executive that is no less favorable to Executive in any respect than the coverage then being provided to any other current or former director or officer of the Company.

7.3    For purposes of this Agreement, the following terms shall have the following meanings: “Affiliate” of a Person shall mean any Person that directly or indirectly controls, is controlled by, or is under common control with, such Person; “Claim” shall mean any claim, demand, request, investigation, dispute, controversy, threat, discovery request, or request for testimony or information; “Person” shall mean any individual, corporation, partnership, limited liability company, joint venture, trust, estate, board, committee, agency, body, employee benefit plan, or other person or entity; and “Proceeding” shall mean any threatened or actual action, suit or proceeding, whether civil, criminal, administrative, investigative, appellate, formal, informal or other.

7.4    The Company hereby agrees that, for purposes of determining whether any parachute payment would be subject to the excise tax under Section 4999 of the Code (the “Excise Tax”), the non-compete set forth in Section 9.2 (the “Non-Compete Provision”) shall be treated as an agreement for the performance of personal services. The Company hereby agrees to indemnify, defend, and hold Executive harmless from and against any adverse impact, tax, penalty, or excise tax resulting from the Company or Accountants’ attribution of a value to the Non-Compete Provision that is less than the product of (i) the greater of (A) the total compensation amount that would be disclosed under Item 402(c) of Securities and Exchange Commission Regulation S-K if Executive had been a “named executive officer” of the Company in the year prior to the year of the event that triggers the Excise Tax or (B) an independent valuation of the Non-Compete Provision, multiplied by (ii) the duration of the Non-Compete Provision in years (this product, the “Post Change in Control Reasonable Compensation”), to the extent that use of such lesser amount results in a larger excise tax under Section 4999 of the Code than Executive would have been subject to had the Company or Accountants attributed a value to the Non-Compete Provision that is at least equal to the Post Change in Control Reasonable Compensation.

8.Other Tax Matters.

8.1    The Company shall withhold all applicable federal, state and local taxes, social security and workers’ compensation contributions and other amounts as may be required by law with respect to compensation payable to Executive pursuant to this Agreement.

8.2    Notwithstanding anything herein to the contrary, this Agreement is intended to be interpreted and applied so that the payment of the benefits, severance, incentive compensation and/or equity compensation set forth herein shall either be exempt from the requirements of Section 409A of the Code (“Section 409A”) or shall comply with the requirements of such provision. If the Company and Executive reasonably agree that this Agreement is not in compliance with Section 409A, the parties shall in good faith attempt to modify this Agreement to comply with Section 409A while endeavoring to maintain the intended economic benefits hereunder. Notwithstanding any provision of this Agreement to the contrary, if Executive is a “specified employee” within the meaning of Section 409A, any payments due upon a termination of Executive’s employment under any arrangement that constitutes a “deferral of compensation” within the meaning of Section 409A and which do not otherwise qualify under the exemptions under Treas. Regs. Section 1.409A-1 (including without limitation, the short-term deferral exemption or the permitted payments under Treas. Regs. Section 1.409A-1(b)(9)(iii)(A)), shall be delayed and paid or provided on the earlier of (i) the date which is six months after Executive’s “separation from service” (as such term is defined in Section 409A and the regulations and other published guidance thereunder) for any reason other than death, and (ii) the date of Executive’s death.

8.3    After any Termination Date, Executive shall have no duties or responsibilities that are inconsistent with having a “separation from service” within the meaning of Section 409A as of the Termination Date and, notwithstanding anything in the Agreement to the contrary, distributions upon termination of employment may only be made upon a “separation from service” as determined under Section 409A and such date shall be the Termination Date for purposes of this Agreement. Each payment under this Agreement or otherwise shall be treated as a separate payment for purposes of Section 409A. In no event may Executive, directly or indirectly, designate the calendar year of any payment to be made under this Agreement which constitutes a “deferral of compensation” within the meaning of Section 409A.

8.4    Any amounts otherwise payable to Executive following a termination of employment that are not so paid by reason of this Section 8 shall be paid as soon as practicable following, and in any event within thirty (30) days following, the date that is six months after Executive’s separation from service (or, if earlier, the date of Executive’s death). All reimbursements and in-kind benefits provided under this Agreement shall be made or provided in accordance with the requirements of Section 409A.

8.5    To the extent that any reimbursements pursuant to Section 4.3 or otherwise are taxable to Executive, any reimbursement payment due to Executive pursuant to such Section shall be paid to Executive on or before the last day of the Executive’s taxable year following the taxable year in which the related expense was incurred. The reimbursements pursuant to Section 4.3 or otherwise are not subject to liquidation or exchange for another benefit and the amount of such reimbursements that Executive receives in one taxable year shall not affect the amount of such reimbursements that Executive receives in any other taxable year.

9.Restrictive Covenants.

9.1    Confidentiality.

9.2    Non-Competition.

(a)    Executive acknowledges that, during the Term, Executive has had access to information concerning the Company’s critical business strategies, engineering and technology development plans, competitive analyses, organizational structure. Accordingly, in consideration of the compensation provided under this Agreement, Executive agrees that during the Term and for the twenty-four (24)-month period thereafter (provided, that, in the event of a Change in Control this twenty-four (24) month period shall be reduced to twelve (12) months), Executive will not directly or indirectly, (i) own,

manage, operate, control (including indirectly through a debt or equity investment), provide services to, or be employed by, any person or entity engaged in any business that is (A) located in or provides services or products to a region in which the Company does business (or in which the Company has taken substantial steps to do business), and (B) competitive with the business activities of the Company as they existed during the period that Executive provided services to the Company (or with business activities in which the Company has taken substantial steps to engage); provided, that, following the Term this clause (i) shall only apply to business activities of the Company as they existed as of the Termination Date (or to business activities in which the Company has taken substantial steps to engage as of the Termination Date); (ii) solicit, induce, encourage, or attempt to induce or encourage any employee or consultant of the Company to terminate his or her employment or consulting relationship with the Company, or to breach any other obligation to the Company (other than advertising not specifically targeted at the Company’s employees and serving as a reference upon request); or (iii) interfere with, disrupt, alter, or attempt to disrupt or alter the relationship, contractual or otherwise, between the Company and any consultant, contractor, customer, potential customer, or supplier of the Company.

(b)    Executive acknowledges that the restrictions contained under this Section 9.2 are reasonable and necessary to protect the legitimate interests of the Company, that the Company would not have executed this Agreement in the absence of such restrictions, and that any violation of any provision of this paragraph will result in irreparable injury to the Company. In the event the provisions under this Section 9.2 shall ever be deemed to exceed the time, scope or geographic limitations permitted by applicable laws, then such provisions shall be reformed to the maximum time, scope or geographic limitations, as the case may be, permitted by applicable laws.

9.3    Injunctive Relief. Executive agrees that it is impossible to measure in money the damages which will accrue to the Company by reason of a failure by Executive to perform any of Executive’s obligations under this Section 9. Accordingly, if Company or any of its affiliates institutes any action or proceeding to enforce its rights under this Section 9, to the extent permitted by applicable law, Executive hereby waives the claim or defense that the Company or its affiliates has an adequate remedy at law, and Executive shall not claim that any such remedy at law exists.

No failure to exercise and no delay in exercising any right, remedy, or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any right, remedy, or power hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, or power provided herein or by law or in equity. To be effective, any written waiver must specifically refer to the condition(s) or provision(s) of this Agreement being waived.

15.Inconsistencies.

THIS GENERAL RELEASE OF ALL CLAIMS (this “General Release”), dated as of ________, is made by and between Sarah M. London (“Executive”) and Centene Corporation (together with its successors and assigns, the “Company”).

WHEREAS, the Company and Executive are parties to that certain Employment Agreement, dated as of April 27, 2022 (the “Employment Agreement”);

WHEREAS, Executive’s employment with the Company has been terminated and Executive is entitled to receive severance and other benefits, as set forth in Section 5 of the Employment Agreement subject to the execution of this General Release;

WHEREAS, in consideration for Executive’s signing of this General Release, the Company will provide Executive with such severance and benefits pursuant to the Employment Agreement; and

WHEREAS, except as otherwise expressly set forth herein, the parties hereto intend that this General Release shall effect a full satisfaction and release of the obligations described herein owed to Executive by the Company and to the Company by Executive.

NOW, THEREFORE, in consideration of the premises, the mutual covenants of the parties hereinafter set forth and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby covenant and agree as follows:

1. Executive, for Executive, Executive’s spouse, heirs, administrators, children, representatives, executors, successors, assigns, and all other individuals and entities claiming through Executive, if any (collectively, the “Executive Releasers”), does hereby release, waive, and forever discharge the Company and each of its respective agents, subsidiaries, parents, affiliates, related organizations, employees, officers, directors, attorneys, successors, and assigns in their capacities as such (collectively, the “Employer Releasees”) from, and does fully waive any obligations of Employer Releasees to Executive Releasers for, any and all liability, actions, charges, causes of action, demands, damages, or claims for relief, remuneration, sums of money, accounts or expenses (including attorneys’ fees and costs) of any kind whatsoever, whether known or unknown or contingent or absolute, which heretofore has been or which hereafter may be suffered or sustained, directly or indirectly, by Executive Releasers in consequence of, arising out of, or in any way relating to: (a) Executive’s employment with the Company; (b) the termination of Executive’s employment with the Company; (c) the Employment Agreement; or (d) any events relating to Executive’s employment occurring on or prior to the date of this General Release. The foregoing release and discharge, waiver and covenant not to sue includes, but is not limited to, all waivable claims and any obligations or causes of action arising from such claims, under common law including wrongful or retaliatory discharge, breach of contract (including but not limited to any claims under the Employment Agreement other than claims for unpaid severance benefits, bonus or Salary earned thereunder) and any action arising in tort including libel, slander, defamation or intentional infliction of emotional distress, and claims under any federal, state or local statute including the Age Discrimination in Employment Act (“ADEA”), Title VII of the Civil Rights Act of 1964, the Civil Rights Act of 1866 and 1871 (42 U.S.C. § 1981), the National Labor Relations Act, the Fair Labor Standards Act, the Employee Retirement Income Security Act, the Americans with Disabilities Act of 1990, the Rehabilitation Act of 1973, or the discrimination or employment laws of any state or municipality, and/or

any claims under any express or implied contract which Executive Releasers may claim existed with Employer Releasees. This also includes a release of any claims for wrongful discharge and all claims for alleged physical or personal injury, emotional distress relating to or arising out of Executive’s employment with the Company or any of its subsidiaries or affiliates or the termination of that employment; and any claims under the WARN Act or any similar law, which requires, among other things, that advance notice be given of certain work force reductions. Notwithstanding anything contained in this Section 1 above to the contrary, nothing contained in herein shall constitute a release by any Executive Releaser of any of his, her or its rights or remedies available to him, her or it, at law or in equity, related to, on account of, in connection with or in any way pertaining to the enforcement of: (i) any right to indemnification, advancement of legal fees or directors and officers liability insurance coverage existing under the constituent documents of the Company or applicable state corporate, limited liability company and partnership statutes or pursuant to any agreement, plan or arrangement; (ii) any rights to the receipt of employee benefits which vested on or prior to the date of this General Release; (iii) the right to receive severance and other benefits under the Employment Agreement; (iv) the right to continuation coverage pursuant to the Consolidated Omnibus Budget Reconciliation Act; (v) any equity rights; or (vi) this General Release or any of its terms or conditions.

2. Excluded from this General Release and waiver are any claims which cannot be waived by applicable law, including but not limited to the right to participate in an investigation conducted by certain government agencies. Executive does, however, waive Executive’s right to any monetary recovery should any government agency (such as the Equal Employment Opportunity Commission) pursue any claims on Executive’s behalf. Executive represents and warrants that Executive has not filed any complaint, charge, or lawsuit against the Employer Releasees with any government agency or any court.

3. Executive agrees never to seek personal recovery from any Employer Releasee in any forum for any claim covered by the above waiver and release language, except that Executive may bring a claim under the ADEA to challenge this General Release. If Executive violates this General Release by suing an Employer Releasee (excluding any claim by Executive under the ADEA or as otherwise set forth in Section 1 hereof), then Executive shall be liable to the Employer Releasee so sued for such Employer Releasee’s reasonable attorneys’ fees and other litigation costs incurred in defending against such a suit. Nothing in this General Release is intended to reflect any party’s belief that Executive’s waiver of claims under ADEA is invalid or unenforceable, it being the intent of the parties that such claims are waived.

4. The Employer Releasees do hereby release, waive, and forever discharge Executive, Executive’s heirs, personal representatives and assigns, and any and all other persons or entities that are now or may become liable to any Employer Releasee due to Executive’s act or omission (all of whom are collectively referred to as “Executive Releasees”), from, and do fully waive any obligations of Executive Releasees to Employer Releasees for, any and all liability, actions, charges, causes of action, demands, damages, or claims for relief, remuneration, sums of money, accounts or expenses (including attorneys’ fees and costs) of any kind whatsoever, whether known or unknown or contingent or absolute, that the Employer Releasees, or any person acting under any of them, may now have, or claim at any future time to have, based in whole or in part upon any act or omission occurring from the beginning of time through the date of execution of this General Release.

5. Each party agrees that neither this General Release, nor the furnishing of the consideration for this General Release, shall be deemed or construed at any time to be an admission by any party of any improper or unlawful conduct.

6. Each party acknowledges and recites that he or it has:

Executive acknowledges and agrees that (a) Executive’s execution of this General Release has not been forced by any employee or agent of the Company, and Executive has had an opportunity to negotiate the terms of this General Release; and (b) Executive has been offered twenty-one (21) calendar days after receipt of this General Release to consider its terms before executing it. Executive shall have seven (7) calendar days from the date he executes this General Release to revoke Executive’s waiver of any ADEA claims by providing written notice of the revocation to the Company, as provided in Section 11 of the Employment Agreement.
