Transition and Separation Agreement

Dear Xiao:

This letter agreement (this “Agreement”) sets out the terms and conditions that we previously discussed regarding your employment with Thoughtworks, Inc. (the “Company”). This Agreement shall be effective as of the date signed by you (such date, the “Effective Date”).

In recognition of your prior service, and in order to facilitate a smooth transition of your duties, we would like you to provide services as an employee of the Company for a transition period on the terms set forth in this Agreement as well as services as a consultant after your employment terminates.

(a)Transition and Termination of Employment. From the Effective Date through the Employment Termination Date (as defined below) (such period, the “Transition Period”), you will continue to be an employee of the Company. During the Transition Period, your duties will be as reasonably directed by the Company’s board of directors or its designee, including, without limitation, transitioning your prior duties and responsibilities. During the Transition Period, you shall devote substantial business time and efforts to the performance of your services to the Company. Until the commencement of employment of a new Chief Executive Officer (the date of such officer’s commencement of employment with the Company is the “New CEO Hire Date”), your title will remain Chief Executive Officer, reporting to the Company’s Board of Directors and thereafter, your title will be Senior Advisor. You acknowledge and agree that the Company’s hiring of a new Chief Executive Officer (and any related change in title or transition of your duties) will not constitute “Good Reason” for purposes of the Thoughtworks Holding, Inc. Executive Severance Plan (the “Severance Plan”) or the Employment Agreement between you and the Company dated as of October 12, 2017 (the “Employment Agreement”). For purposes of this Agreement, the “Employment Termination Date” shall be the date occurring three (3) months following the New CEO Hire Date; provided, however, that (i) you may elect to terminate your employment at any time and for any reason, (ii) the Company may terminate your employment for Cause (as defined in the Employment Agreement) at any time during the Transition Period if Cause exists, and (iii) the Company may terminate your employment without Cause at any time on or after a Change in Control (as defined in the Company’s 2021 Omnibus Incentive Plan). (For the avoidance of doubt, the Company cannot terminate your employment without Cause during the Transition Period prior to a Change in Control.) If your employment with the Company terminates before the date occurring three (3) months after the New CEO Hire Date, the date of your termination of employment will be the Employment Termination Date.

(b)Consulting Services. If your employment terminates upon the expiration of the Transition Period in the natural course (i.e., three (3) months following the New CEO Hire

Date or your resignation for Good Reason (as defined in the Severance Plan), as compared to your earlier resignation without Good Reason or a termination due to your death or Disability (as defined in the Employment Agreement) or a termination by the Company for Cause, such a termination in the natural course, a “Natural Course Termination”), then during the period commencing on the Employment Termination Date and ending on June 17, 2025 (the “Consulting Period”), you will be engaged as a consultant and shall provide services to the Company with respect to such projects as reasonably requested by the Company’s Chief Executive Officer, including, without limitation, services related to the transition of your prior duties and responsibilities (the “Services”); provided that such Services shall not materially interfere with any employment or other consulting by you. The Company may terminate the Consulting Period if, and only if, it determines, in its reasonable discretion, that you are not performing the Services in good faith. Your relationship with the Company during the Consulting Period will be that of an independent contractor and not that of an employee. You shall be solely responsible for determining the method, details and means of performing the Services and you will have no authority to enter into contracts that bind the Company or create obligations on the part of the Company without the prior written authorization of the Company. In addition, you agree to execute the Company’s standard form of confidential information and invention assignment agreement for consultants if requested by the Company.

(a)Transition Period. So long as you remain employed during the Transition Period, (a) the Company shall continue to pay you your current base salary until the New CEO Hire Date, and for the period commencing on the first day after the New CEO Hire Date, the Company will pay you an aggregate amount of base salary of $200,000 (such amount based on the assumption that you remain employed through the date occurring three (3) months after the New CEO Hire Date), prorated and ratably paid in accordance with the Company’s standard payroll periods subject to your continued employment, (b) you will remain eligible to participate in the Company’s general employee benefit plans on terms consistent with those provided to all other employees and (c) you will continue to vest in any equity awards granted to you by Thoughtworks Holding, Inc. (“Holding”) in accordance with the terms of the agreements evidencing such awards.

(b)Consulting Period. During the Consulting Period, the Company will pay you a total of $50,000 (assuming continued service through June 17, 2025) as fees for services, in substantially equivalent monthly installments (and pro-rated for any partial months), payable on the last day of the applicable service month. You acknowledge and agree that you will only be eligible to receive the compensation described in the preceding sentence with respect to the Services and you will not be eligible for any other Company employee benefits, although you will continue to vest during the Consulting Period in any equity awards granted to you by Holding. Your compensation for the Services will not be subject to withholding by the Company for the payment of any taxes and the Company will report amounts paid to you on a Form 1099-NEC.

3.Termination of Employment. Notwithstanding any contrary provision herein, your employment is “at will” and may be terminated at any time by either you or the Company, for any or no reason; provided, however, that the Company may not terminate your employment without Cause during the Transition Period prior to a Change in Control. Upon any termination of

(a)Severance. If your employment terminates due to a Natural Course Termination, then, notwithstanding the agreed upon termination of your employment, you shall be eligible for severance benefits under the Severance Plan, at the CEO level, as if your employment had been terminated by the Company without Cause, subject to the terms and conditions of the Severance Plan (including, without limitation, a release of claims (in substantially the form attached hereto as Exhibit A, but as the Company may reasonably revise to reflect changes in applicable law), the Code Section 409A provisions set forth in Section 6 of the Severance Plan, and the limitation on payments set forth in Section 7 of the Severance Plan); provided, however, that (i) your Base Cash Severance (as defined in the Severance Plan) will be calculated based on your annual base salary as of the date immediately preceding the Effective Date, (ii) you will receive the full amount of your Target Bonus (as defined in the Severance Plan) instead of a Pro- Rata Target Bonus (as defined in the Severance Plan), (iii) subject to your continued compliance with your post-employment obligations, your options to purchase shares of common stock of Holding shall remain exercisable for a period of three (3) years commencing on the New CEO Hire Date (provided that in no event shall an option be exercisable later than its original maximum term and the options are subject to earlier termination in the event of a Change in Control (or similar event) as provided in the applicable equity plan pursuant to which it was granted), and (iv) subject to your continued compliance with your post-employment obligations and the continuation of the Consulting Period through June 14, 2025, on June 14, 2025 you shall vest in 50% of your outstanding restricted stock units that otherwise were scheduled to vest in 2025 solely subject to continued service if, as of June 14, 2025 such restricted stock units had not otherwise vested pursuant to the Severance Plan, applicable equity plan, or applicable award agreement (such benefits, collectively in clauses (i) through (iv), and along with the payments and benefits under the Severance Plan, the “Severance Benefits”). For the avoidance of doubt, if your employment terminates for any reason other than (i) a Natural Course Termination or (ii) due to a termination by the Company without Cause, you will not be entitled to the Severance Benefits.

(b)Termination. Upon the Employment Termination Date, your employment and service in any position you hold with the Company (other than with respect to the Services to be provided pursuant to this Agreement) and any of its affiliates and any of its affiliates or direct or indirect subsidiaries, shall terminate; provided, however, that your service on the Board of Directors of Holding shall terminate on the New CEO Hire Date. Upon the Employment Termination Date (or the New CEO Hire Date with respect to service on the board of directors of Holding), you agree to execute any letter of resignation consistent with the foregoing that the Company may reasonably request.

4.Restrictive Covenants. You acknowledge, are reminded of, and affirm your agreement to abide by the terms and conditions of the restrictive covenants set forth in Sections 7, 8, and 9 of the Employment Agreement (which such provisions are hereby incorporated herein by this reference).

5.Withholding. All amounts payable to you pursuant to this Agreement shall be subject to such withholding and deductions by the Company as is required by law and any applicable benefit plans.

6.Assignment. This Agreement is binding upon and shall inure to the benefit of the parties hereto and their respective successors and permitted assigns. You shall not assign or transfer any rights or obligations hereunder. The Company shall have the right to assign or transfer any rights or obligations hereunder only to (a) a successor corporation in the event of a merger, consolidation, or transfer or sale of all or substantially all of the assets, of the Company or (b) an affiliate of the Company. No such assignment referred to in the foregoing clause (a) or (b) shall relieve the Company of its obligations hereunder. Any purported assignment, other than as provided above, shall be null and void.

7.Notices. All notices, requests, consents and other communications required or permitted to be given hereunder, shall be in writing and shall be delivered personally, via e-mail, or sent by prepaid overnight courier or mailed, first class, postage prepaid by registered or certified mail, as follows:

Any such notice shall be deemed given when so delivered personally, e-mailed, or if sent by overnight courier, one day after delivery to such courier by the sender or if mailed, five days after deposit by the sender in the U.S. Mail.

8.Entire Agreement; Non-Exclusive Rights. This Agreement shall constitute the entire agreement between you, on the one hand, and the Company, on the other hand, concerning the subject matter hereof. No provision of this Agreement may be modified, amended, waived or discharged unless such waiver, modification, amendment or discharge is agreed to in writing, signed by you and an authorized officer of the Company. For the avoidance of doubt, this Agreement, once effective, supersedes all prior agreements regarding your employment (and the termination thereof) with the Company or any of its respective affiliates, including, without limitation, the Employment Agreement (although provisions of the Employment Agreement have been incorporated herein).

10.Severability. If any provision of this Agreement or the application thereof is held invalid, the invalidity shall not affect the other provisions or applications of this Agreement which can be given effect without the invalid provisions or applications and to this end the provisions of this Agreement are declared to be severable.
