WHEREAS, the Company desires to employ the Executive as its Chief Financial Officer and the Executive desires to serve in such capacity on behalf of the Company. NOW, THEREFORE, in consideration of the premises and of the mutual covenants and agreements hereinafter set forth, the Company and the Executive hereby agree as follows: 1. Employment. (a) Term. The term of this Agreement and the effective date of the Executive’s commencement of employment with the Company shall begin on March 25, 2024 (the “Effective Date”) and shall continue for four years from the Effective Date, or until the termination of the Executive’s employment, if earlier (the “Term”). (b) Duties. During the Term, the Executive shall serve as the Chief Financial Officer of the Company, with such duties, responsibilities and authority commensurate therewith, and shall report to the Chief Executive Officer of the Company (the “CEO”). The Executive shall perform all duties and accept all responsibilities incident to such position as may be reasonably assigned to the Executive by the CEO. (c) Best Efforts. During the Term, the Executive shall devote his best efforts and full time and attention to promote the business and affairs of the Company and its affiliated entities, and shall be engaged in other business activities only to the extent that such activities do not materially interfere or conflict with the Executive’s obligations to the Company hereunder, including, without limitation, obligations pursuant to Section 14 below. The foregoing shall not be construed as preventing the Executive from (i) serving on civic, educational, philanthropic or charitable boards or committees, or, with the prior written consent of the Board, on corporate boards, and (ii) managing personal investments, in each case so long as such activities are permitted under the Company’s code of conduct and employment policies and do not violate the provisions of Section 14 below. (d) Principal Place of Employment. The Executive understands and agrees that his principal place of employment will be in the Company’s offices located in Oaks, Pennsylvania and that the Executive will be required to travel for business in the course of performing his duties for the Company. 2. Compensation. (a) Base Salary. During the Term, the Company shall pay the Executive a base salary (“Base Salary”), at the annual rate of $750,000.00 which shall be paid in installments in accordance with the Company’s normal payroll practices. The Executive’s Base Salary shall be reviewed annually by the Compensation Committee of the Board (the “Compensation

2 Committee”) pursuant to the normal performance review policies for senior-level executives and may be increased from time to time as the Board deems appropriate. (b) Annual Bonus. The Executive shall be eligible to receive an annual bonus for each fiscal year during the Term, commencing with the 2024 fiscal year, based on the attainment of individual and corporate performance goals and targets established by the Board (“Annual Bonus”). The target amount of the Executive’s Annual Bonus for any fiscal year during the Term, including 2024, is $1,700,000.00; provided that actual payout of the Annual Bonus will be determined by the Board or Compensation Committee in its discretion based on the achievement of applicable performance goals for the relevant performance period. Notwithstanding the foregoing, for 2024, the Annual Bonus will be guaranteed paid at the target amount above, prorated based on the Effective Date and payable at 100% of the prorated amount. Any Annual Bonus shall be paid after the end of the fiscal year to which it relates, at the same time and under the same terms and conditions as the bonuses are paid to other executives of the Company; provided, that in no event shall the Executive’s Annual Bonus be paid later than two and a half months after the last day of the fiscal year to which the Annual Bonus relates. The Annual Bonus shall be subject to the terms of the annual bonus plan that is applicable to other executives of the Company, including requirements as to continued employment. (c) Staking Grant. Upon, or as soon as practicable following, the Effective Date, the Board or Compensation Committee shall grant the Executive a restricted stock unit grant with respect to 45,000 shares of the Company’s common stock, which will vest ratably over three years from the Effective Date, with 33.33% of the award vesting each year starting on the first anniversary of the Effective Date (the “Staking Grant”). Vesting is conditioned on continued employment through the specified vesting dates, subject to Sections 6, 9, and 10 below. The Staking Grant will be made under the Company’s 2014 Omnibus Equity Compensation Plan, with such terms as the Board or Compensation Committee deems appropriate, consistent with the terms of this Agreement and applicable law. (d) Annual Equity Grants. During the Term, if the Executive is an employee in good standing and has met the Board’s performance expectations, as determined in the sole discretion of the Board or the Compensation Committee by considering such factors as the Board or the Compensation Committee may them deem appropriate, then the Executive shall be eligible to receive annual equity awards under the Company’s 2014 Omnibus Equity Compensation Plan or a successor plan on the same terms and in substantially similar value, as awards to other similarly situated senior executives of the Company, starting in December 2024. Notwithstanding the foregoing, upon, or as soon as practicable following, the Effective Date, the Board or Compensation Committee shall grant the Executive an option to purchase 22,500 shares of the Company’s common stock, and in December 2024 grant to the Executive 15,000 restricted stock units and an option to purchase 22,500 shares of the Company’s common stock, in each case, with an exercise price for such options and vesting and other terms similar to the annual equity awards granted to other similarly situated senior executives at that time, as determined by the Board or Compensation Committee. 3.

During the Term, the Executive shall be eligible to participate in the Company’s health, life insurance, long-term disability, retirement and welfare benefit plans and programs available to employees of the Company, pursuant to their respective

Termination Without Cause. The Company may terminate the Executive’s employment with thirty (30) days’ advance notice without Cause. Upon termination by the Company without Cause during the Term, if the Executive executes and does not revoke a written Release (as defined below), the Executive shall be entitled to receive, in lieu of any payments under any severance plan or program for employees or executives, the following: (a) The Company will pay the Executive an amount equal to the sum of (x) the amount of the Executive’s annual Base Salary as of the termination date and (y) the amount of the Executive’s target Annual Bonus for the year of termination.

6 13. Section 409A. (a) This Agreement is intended to comply with Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), and its corresponding regulations, or an exemption thereto, and payments may only be made under this Agreement upon an event and in a manner permitted by section 409A of the Code, to the extent applicable. Severance benefits under this Agreement are intended to be exempt from section 409A of the Code under the “short-term deferral” exception, to the maximum extent applicable, and then under the “separation pay” exception, to the maximum extent applicable. Notwithstanding anything in this Agreement to the contrary, if required by section 409A of the Code, if the Executive is considered a “specified employee” for purposes of section 409A of the Code and if payment of any amounts under this Agreement is required to be delayed for a period of six months after separation from service pursuant to section 409A of the Code, payment of such amounts shall be delayed as required by section 409A of the Code, and the accumulated amounts shall be paid in a lump-sum payment within 10 days after the end of the six-month period. If the Executive dies during the postponement period prior to the payment of benefits, the amounts withheld on account of section 409A of the Code shall be paid to the personal representative of the Executive’s estate within 60 days after the date of the Executive’s death. (b) All payments to be made upon a termination of employment under this Agreement may only be made upon a “separation from service” under section 409A of the Code. For purposes of section 409A of the Code, each payment hereunder shall be treated as a separate payment, and the right to a series of installment payments under this Agreement shall be treated as a right to a series of separate payments. In no event shall the timing of the Executive’s execution of the Release, directly or indirectly, result in the Executive’s designating the fiscal year of payment of any amounts of deferred compensation subject to section 409A of the Code, and, to the extent required by section 409A of the Code, if a payment that is subject to execution of the Release could be made in more than one taxable year, payment shall be made in the later taxable year. All reimbursements and in-kind benefits provided under this Agreement shall be made or provided in accordance with the requirements of section 409A of the Code. 14. Restrictive Covenants. (a) The Executive agrees to comply with the obligations set forth in the Confidentiality, Non-Solicitation and Non-Competition Agreement, attached as Exhibit B hereto, and any other restrictive covenants agreement that the Company and the Executive may enter into from time to time. (b) Nothing in this Agreement shall prohibit or restrict the Executive from initiating communications directly with, responding to any inquiry from, providing testimony before, providing confidential information to, reporting possible violations of law or regulation to, or filing a claim or assisting with an investigation directly with a self-regulatory authority or a government agency or entity, including the Equal Employment Opportunity Commission, the Department of Labor, the National Labor Relations Board, the Department of Justice, the Securities and Exchange Commission, Congress, any agency Inspector General or any other federal, state or local regulatory authority, or from making other disclosures that are protected under the whistleblower provisions of state or federal law or regulation. Please take notice that

7 federal law provides criminal and civil immunity to federal and state claims for trade secret misappropriation to individuals who disclose trade secrets to their attorneys, courts, or government officials in certain, confidential circumstances that are set forth at 18 U.S.C. §§ 1833(b)(1) and 1833(b)(2), related to the reporting or investigation of a suspected violation of the law, or in connection with a lawsuit for retaliation for reporting a suspected violation of the law. 15. Venue; Breach of Obligations. (a) The Executive irrevocably and unconditionally (1) agrees that any legal proceeding arising out of this Agreement shall be brought solely in the United States District Court for the Eastern District of Pennsylvania, or if such court does not have jurisdiction or will not accept jurisdiction, in any court of general jurisdiction in the Commonwealth of Pennsylvania (2) consents to the exclusive jurisdiction of such court in any such proceeding, and (3) waives any objection to the laying of venue of any such proceeding in any such court. The Executive also irrevocably and unconditionally consents to the service of any process, pleadings, notices or other papers. (b) Notwithstanding anything in this Agreement to the contrary, if a court of competent jurisdiction issues a final, non-appealable order that the Executive breached any of the Executive’s obligations under Section 14, the Company shall be obligated to provide only the Accrued Obligations, and all payments under Section 2 or Section 6 hereof, as applicable, shall cease. In such event, the Company may require that the Executive repay all amounts theretofore paid to him pursuant to Section 6 hereof (other than Section 6(c)), and in such case, the Executive shall promptly repay such amounts on the terms determined by the Company. 16. Survival. The respective rights and obligations of the parties under this Agreement (including, but not limited to, under Sections 14 and 15) shall survive any termination of the Executive’s employment or termination or expiration of this Agreement to the extent necessary to the intended preservation of such rights and obligations. 17. No Mitigation. In no event shall the Executive be obligated to seek other employment or take any other action by way of mitigation of the amounts payable to the Executive under any of the provisions of this Agreement, and such amounts shall not be reduced as a result of Executive obtaining other employment. 18. Section 280G. In the event of a change in ownership or control under section 280G of the Code, if it shall be determined that any payment or distribution in the nature of compensation (within the meaning of section 280G(b)(2) of the Code) to or for the benefit of the Executive, whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise (a “Payment”), would constitute an “excess parachute payment” within the meaning of section 280G of the Code, the aggregate present value of the Payments under this Agreement shall be reduced (but not below zero) to the Reduced Amount (defined below) if and only if the Accounting Firm (described below) determines that the reduction will provide the Executive with a greater net after-tax benefit than would no reduction. No reduction shall be made unless the reduction would provide Executive with a greater net after-tax benefit. The determinations under this Section shall be made as follows:

8 (a) The “Reduced Amount” shall be an amount expressed in present value which maximizes the aggregate present value of Payments under this Agreement without causing any Payment under this Agreement to be subject to the Excise Tax (defined below), determined in accordance with section 280G(d)(4) of the Code. The term “Excise Tax” means the excise tax imposed under section 4999 of the Code, together with any interest or penalties imposed with respect to such excise tax. (b) Payments under this Agreement shall be reduced on a nondiscretionary basis in such a way as to minimize the reduction in the economic value deliverable to the Executive, consistent with section 409A of the Code. Where more than one payment has the same value for this purpose and they are payable at different times, they will be reduced on a pro rata basis. Only amounts payable under this Agreement shall be reduced pursuant to this Section. (c) All determinations to be made under this Section shall be made by an independent certified public accounting firm selected by the Company and agreed to by the Executive immediately prior to the change-in-ownership or -control transaction (the “Accounting Firm”). The Accounting Firm shall provide its determinations and any supporting calculations both to the Company and the Executive within 10 days of the transaction. Any such determination by the Accounting Firm shall be binding upon the Company and the Executive. All of the fees and expenses of the Accounting Firm in performing the determinations referred to in this Section shall be borne solely by the Company. 19. Notices. All notices and other communications required or permitted under this Agreement or necessary or convenient in connection herewith shall be in writing and shall be deemed to have been given when hand delivered or mailed by registered or certified mail, as follows (provided that notice of change of address shall be deemed given only when received): (a) If to the Company, to: SEI Investments Company 0 Xxxxxxx Xxxxxx Xxxxx Xxxx, XX 00000 Attn: General Counsel If to the Executive, to the most recent address on file with the Company or to such other names or addresses as the Company or the Executive, as the case may be, shall designate by notice to each other person entitled to receive notices in the manner specified in this Section. 20. Withholding. All payments under this Agreement shall be made subject to applicable tax withholding, and the Company shall withhold from any payments under this Agreement all federal, state and local taxes as the Company is required to withhold pursuant to any law or governmental rule or regulation. The Executive shall bear all expense of, and be solely responsible for, all federal, state and local taxes due with respect to any payment received under this Agreement. 21. Remedies Cumulative; No Waiver. No remedy conferred upon a party by this Agreement is intended to be exclusive of any other remedy, and each and every such remedy shall be

9 cumulative and shall be in addition to any other remedy given under this Agreement or now or hereafter existing at law or in equity. No delay or omission by a party in exercising any right, remedy or power under this Agreement or existing at law or in equity shall be construed as a waiver thereof, and any such right, remedy or power may be exercised by such party from time to time and as often as may be deemed expedient or necessary by such party in its sole discretion. 22. Assignment. All of the terms and provisions of this Agreement shall be binding upon and inure to the benefit of and be enforceable by the respective heirs, executors, administrators, legal representatives, successors and assigns of the parties hereto, except that the duties and responsibilities of the Executive under this Agreement are of a personal nature and shall not be assignable or delegable in whole or in part by the Executive. The Company may assign its rights, together with its obligations hereunder, in connection with any sale, transfer or other disposition of all or substantially all of its business and assets, and such rights and obligations shall inure to, and be binding upon, any successor to the business or any successor to substantially all of the assets of the Company, whether by merger, purchase of stock or assets or otherwise, which successor shall expressly assume such obligations, and the Executive acknowledges that in such event the obligations of the Executive hereunder, including but not limited to those under Section 14, will continue to apply in favor of the successor. 23. Company Policies. This Agreement and the compensation payable hereunder shall be subject to any applicable clawback or recoupment policies, share trading policies, and other policies that may be implemented by the Board from time to time with respect to officers of the Company. 24. Entire Agreement. This Agreement sets forth the entire agreement of the parties hereto and supersedes any and all prior agreements and understandings concerning the Executive’s employment by the Company. This Agreement may be changed only by a written document signed by the Executive and the Company. 25. Severability. If any provision of this Agreement or application thereof to anyone or under any circumstances is adjudicated to be invalid or unenforceable in any jurisdiction, such invalidity or unenforceability shall not affect any other provision or application of this Agreement, which can be given effect without the invalid or unenforceable provision or application, and shall not invalidate or render unenforceable such provision or application in any other jurisdiction. If any provision is held void, invalid or unenforceable with respect to particular circumstances, it shall nevertheless remain in full force and effect in all other circumstances. 26. Governing Law. This Agreement shall be governed by, and construed and enforced in accordance with, the substantive and procedural laws of the Commonwealth of Pennsylvania without regard to rules governing conflicts of law. 27. Counterparts. This Agreement may be executed in any number of counterparts (including facsimile counterparts), each of which shall be an original, but all of which together shall constitute one instrument.
