Re: Separation Agreement Dear Thomas:

This letter sets forth the substance of the separation agreement (the “Agreement”) between you and IonQ, Inc. (the “Company”).

Transition. Your last day as Chief Financial Officer and your last day of employment with the Company was September 4, 2025 (the “Transition Date”).

Consideration. In reliance on such voluntary representations and the promises and releases contained in this Agreement, the Company will provide you with the following pay and benefits, subject to you signing and not revoking the Release as set forth herein, and complying with the terms hereof:

(a)

Cash Severance. Following your execution of this Agreement, the Company agrees to pay you a gross amount, less all applicable withholdings and deductions, equal to (i) nine (9) months’ of your base salary, (ii) 100% of your 2025 annual target bonus and (iii) a portion of your 2025 annual target bonus, pro-rated to the number of days worked as an employee in 2025 (the “Severance Payment”), pursuant to Section 4.1.1 of the Company’s Executive Severance Plan and your participation agreement thereunder (the “Executive Severance Plan”) for a Covered Termination (as defined in the Executive Severance Plan). The Severance Payment will be made in a single lump sum on the first payroll date following the Release Effective Date (or if such payment timing is not administratively practicable, no more than thirty (30) days following the Release Effective Date).

(b)

Equity Vesting. In 2021 and 2022, you were granted stock options (“Options”), in 2023, 2024 and 2025 you were granted restricted stock units (“RSUs”) and in 2023 you were granted performance-based restricted stock units (“PSUs”) pursuant to the Company’s 2021 Equity Incentive Plan (the “Plan”). Pursuant to Section 4.1.5 of the Executive Severance Plan and your PSU award agreement, you will vest into the number of Options, RSUs and PSUs set forth on Schedule I hereto, subject to your execution and non-revocation of this Agreement. Any other equity awards or portions thereof that do not vest in accordance with Schedule I hereto shall be forfeited on the Transition Date. The RSUs and PSUs in which you vest pursuant to this Section 2(b) will be settled as soon as reasonably practicable following the Release Effective Date, but in no event later than January 31, 2025.

(c)

COBRA Benefits. Your participation as an employee in the Company’s group health insurance plans ended on September 30, 2025. Thereafter, to the extent provided by the Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”) or, if applicable, state insurance laws, and by the Company’s current group health insurance policies, you are eligible to continue your group health insurance benefits for yourself and your dependents. Pursuant to Section 4.1.4 of the Executive Severance Plan, the Company will pay the applicable premiums for such continuation coverage until the earlier of (x) nine (9) months following the Transition Date and (y) the date upon which you become eligible for coverage under a health, dental or vision insurance plan of a subsequent employer (the “COBRA Reimbursement Period”). For the avoidance of doubt, if, following the COBRA Reimbursement Period, you remain eligible for COBRA continuation coverage under applicable law, such continuation coverage will be at your sole cost and expense. You have received additional COBRA information from the Company’s COBRA administrator to your mailing address following the termination of your benefits. Later, you may be able to convert to an individual policy through the provider of the Company’s health insurance, if you wish.

(d)

This Agreement, all of its terms, and all of the obligations of the Company contained herein are expressly contingent upon the condition that you do not exercise your right of revocation as described in Section 13 below.

Accrued Salary. You agree and acknowledge that on or as soon as reasonably practicable following the Transition Date, the Company paid you all of the accrued salary earned through the Transition Date, subject to standard payroll deductions and withholdings. Your receipt of these payments was not subject to whether or not you sign this Agreement. You acknowledge that the Company maintains a non-accrual PTO policy and as a result, you have no accrued but unused PTO that the Company is obligated to pay you upon your separation from employment.

Benefit Plans. Your participation in Employer-Sponsored Group Life Insurance and Short- and Long-Term Disability Insurance, if applicable, ended on the Transition Date. Deductions for the 401(k) Plan ended with your last regular employee paycheck. Your right to vesting with respect to any Company contributions in your 401(k) Plan account will be as set forth in the 401(k) Plan. You received information by mail concerning 401(k) rollover procedures should you be a participant in this program.

No Other Compensation or Benefits. You acknowledge that, except as expressly provided in this Agreement, you will not receive any additional compensation, severance or benefits after the Transition Date.

Expense Reimbursements. You agree that, within ten (10) days of your execution of this Agreement, you will submit your final documented expense reimbursement statement reflecting all business expenses you incurred through the Transition Date, if any, for which you seek reimbursement. The Company will reimburse you for reasonable business expenses pursuant to its regular business practice.

Return of Company Property. You represent that you have already returned to the Company all Company documents (and all copies thereof) and other Company property that you have had in your possession at any time, including, but not limited to, your Company-issued phone, Company files, notes, drawings, records, business plans and forecasts, financial information, specifications, computer-recorded information, tangible property (including, but not limited to, computers), credit cards, entry cards, identification badges and keys; and, any materials of any kind that contain or embody any proprietary or confidential information of the Company (and all reproductions thereof). Receipt of the severance benefits under this Agreement is expressly conditioned upon return of all Company property within five (5) days of the date of this Agreement.

Proprietary Information and Post-Termination Obligations. Both during and after your employment you acknowledge your continuing obligations under your Employee Confidential Information, Inventions, Non-Solicitation and Non-Competition Agreement (“CIIA”) not to use or disclose any confidential or proprietary information of the Company and to refrain from certain solicitation and competitive activities. If you have any doubts as to the scope of the restrictions in your agreement, you should contact the Company immediately to assess your compliance. As you know, the Company will enforce its contractual rights. Please familiarize yourself with the agreement which you signed. Confidential information that is also a “trade secret,” as defined by law, may be disclosed (A) if it is made (i) in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney and (ii) solely for the purpose of reporting or investigating a suspected violation of law; or (B) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. In addition, in the event that you file a lawsuit for retaliation by the Company for reporting a suspected violation of law, you may disclose the trade secret to your attorney and use the trade secret information in the court proceeding, if you: (A) file any document containing the trade secret under seal; and (B) do not disclose the trade secret, except pursuant to court order.

Confidentiality. If and to the extent this Agreement is not publicly filed, summarized or the material terms otherwise publicly disclosed by the Company, the provisions of this Agreement will be held in strictest confidence by you and will not be publicized or disclosed in any manner whatsoever; provided, however, that: (a) you may disclose this Agreement to your immediate family; (b) you may disclose this Agreement in confidence to your attorney, accountant, auditor, tax preparer, and financial advisor; and (c) you may disclose this Agreement as

may be required by law. Notwithstanding the foregoing, nothing in this Agreement shall limit your right to voluntarily communicate with the Equal Employment Opportunity Commission, United States Department of Labor, the National Labor Relations Board, the Securities and Exchange Commission, other federal government agency or similar state or local agency or to discuss the terms and conditions of your employment with others to the extent expressly permitted by Section 7 of the National Labor Relations Act.

10.

Non-Disparagement. You agree not to disparage the Company, the Company Parties or their products, employment practices, business practices, services, or management (whether orally, in written statements, via electronic writings, anonymously, via the internet, or otherwise). You specifically agree that you will not post or make any disparaging reference to the Company or Company Parties on any internet website or through any other social media source. The Company agrees to instruct its current executive officers (known within the Company as the S-team) and members of its Board of Directors not to disparage you (whether orally, in written statements, via electronic writings, anonymously, via the internet, or otherwise). The foregoing shall not preclude any party from (i) testifying truthfully in response to a legally-imposed subpoena or otherwise as required by law, including the Company’s obligations under applicable securities laws or (ii) providing truthful statements or comments in good faith or to the extent reasonably necessary to correct or refute any disparaging public statements.

11.

Cooperation after Termination. In exchange for the payments and benefits provided under this Agreement, without further consideration, you agree to cooperate fully and completely with the Company and any of the other Company Parties with respect to matters on which you worked during you employment and to assist with pending or future legal investigations, proceedings, or litigation, public or private, involving the Company or any of the other Company Parties on matters about which you have personal knowledge. This includes your obligation to promptly meet with representatives of the Company or the other Company Parties, either personally or by telephone, at reasonable times upon their request and without unreasonable interference with your employment or personal activities, and providing information and, where applicable, testimony, that is truthful, accurate, and complete according to information known to you. Reasonable assistance includes, but is not limited to, (i) transitioning any matters on which you worked during your employment to your successor and/or another Company representative; (ii) being available by telephone to answer questions, provide guidance, or discuss matters as needed; (iii) providing information and materials to the Company’s counsel; (iv) providing truthful testimony, if necessary; maintaining the confidentiality of the Company’s and all Company Parties’ privileged or confidential information, including without limitation, attorney-client privileged communications and work product, unless disclosure is expressly authorized by the Company’s legal department; and (v) notifying the Company’s Chief Executive Officer promptly of any requests made for information related to any pending or potential legal claim or litigation involving the Company or any Company Party, reviewing any such requests with a designated representative of the Company prior to disclosing such information, and permitting a representative of the Company to be present during any communication of such information. The Company will use its best efforts to ensure that any assistance requested will be arranged so that it does not unreasonably interfere with your other work or personal commitments. You acknowledge that you will not receive any additional pay for your assistance beyond that provided in Section 2 of this Agreement, but will be reimbursed for any reasonable travel or related costs incurred for services provided under this paragraph.

12.

Release. In exchange for the consideration under this Agreement, to which you would not otherwise be entitled, and except as otherwise set forth in this Agreement, you, on behalf of yourself and, to the extent permitted by law, on behalf of your spouse, heirs, executors, administrators, assigns, insurers, attorneys and other persons or entities, acting or purporting to act on your behalf (collectively, the “Employee Parties”), hereby generally and completely release, acquit and forever discharge the Company, its parents and subsidiaries, and its and their current and former officers, directors, managers, partners, agents, representatives, employees, attorneys, shareholders, predecessors, successors, assigns, insurers and affiliates (the “Company Parties”) of and from any and all claims, liabilities, demands, contentions, actions, causes of action, suits, costs, expenses, attorneys’ fees, damages, indemnities, debts, judgments, levies, executions and obligations of every kind and nature, in law, equity, or otherwise, both known and unknown, suspected and unsuspected, disclosed and undisclosed, arising out of or in any way related to agreements, events, acts or conduct at any time prior to and including the execution date of this Agreement, including but not limited to: all such claims and demands directly or indirectly arising out of or in any way connected with your employment with the Company or your resignation of that employment; claims or demands related to salary, bonuses, commissions, stock, stock options, or any other ownership interests in the Company, vacation pay, fringe benefits, expense reimbursements, severance pay, or any other form of compensation;

claims pursuant to any federal, state or local law, statute, or cause of action; tort law; or contract law (individually a “Claim” and collectively “Claims”).

Notwithstanding the foregoing, other than events expressly contemplated by this Agreement you do not waive or release rights or Claims that may arise from events that occur after the date this waiver is executed. Also excluded from this Agreement are any Claims which cannot be waived by law, including, without limitation, any rights you may have under applicable workers’ compensation laws and your right, if applicable, to file or participate in an investigative proceeding of any federal, state or local governmental agency. Nothing in this Agreement shall prevent you from filing, cooperating with, or participating in any proceeding or investigation before the Equal Employment Opportunity Commission, United States Department of Labor, the National Labor Relations Board, the Occupational Safety and Health Administration, the Securities and Exchange Commission or any other federal government agency, or similar state or local agency (“Government Agencies”), or exercising any rights pursuant to Section 7 of the National Labor Relations Act. You further understand this Agreement does not limit your ability to voluntarily communicate with any Government Agencies or otherwise participate in any investigation or proceeding that may be conducted by any Government Agency, including providing documents or other information, without notice to the Company. While this Agreement does not limit your right to receive an award for information provided to the Securities and Exchange Commission, you understand and agree that, you are otherwise waiving, to the fullest extent permitted by law, any and all rights you may have to individual relief based on any Claims that you have released and any rights you have waived by signing this Agreement. If any Claim is not subject to release, to the extent permitted by law, you waive any right or ability to be a class or collective action representative or to otherwise participate in any putative or certified class, collective or multi-party action or proceeding based on such a Claim in which any of the Company Parties is a party. This Agreement does not abrogate your existing rights under any Company benefit plan or any plan or agreement related to equity ownership in the Company; however, it does waive, release and forever discharge Claims existing as of the date you execute this Agreement pursuant to any such plan or agreement.

13.

Waiver of Claims under the Age Discrimination in Employment Act. You recognize that, in signing this release of Claims (the “Release”), you are waiving your right to pursue any and all claims under the Age Discrimination in Employment Act, 29 U.S.C. § 621 et seq. (“ADEA”) arising prior to the date that each time you execute this Release. You understand that you may take twenty-one (21) days from the date this Release is presented to consider whether to execute this Release. You are advised through this Agreement that you may wish to consult

with an attorney prior to execution of this Release. Once you have executed this Release, you may revoke the Release at any time during the seven (7) day period following your execution of the Release. After seven (7) days have passed following your execution of this Release, your execution of this Release shall be final and irrevocable (such date, the “Release Effective Date”).

14.

You acknowledge and agree that (i) the consideration given to you in exchange for the waiver and release in this Agreement is in addition to anything of value to which you were already entitled; (ii) that you have been paid for all time worked, have received all the leave, leaves of absence and leave benefits and protections for which you are eligible, and have not suffered any on-the-job injury for which you have not already filed a Claim; (iii) you have been given sufficient time to consider this Agreement and to consult an attorney or advisor of your choosing; and (iv) you are knowingly and voluntarily executing this Agreement waiving and releasing any Claims you may have as of the date you execute it. You affirm that all of the decisions of the Company Parties regarding your pay and benefits through the date of your execution of this Agreement were not discriminatory based on age, disability, race, color, sex, religion, national origin or any other classification protected by law.

15.

No Admission. This Agreement does not constitute an admission by the Company of any wrongful action or violation of any federal, state, or local statute, or common law rights, including those relating to the provisions of any law or statute concerning employment actions, or of any other possible or claimed violation of law or rights.

16.

Breach. You agree that upon any breach of this Agreement or the CIIA, you will forfeit the consideration provided to you under this Agreement and any continuing payments or benefits pursuant to Section 2 hereof shall cease immediately. Further, you acknowledge that it may be impossible to assess the damages caused by your violation of the terms of Sections 8, 9, 10, 11, 12 and 13 of this Agreement and further agree that any threatened or actual violation or breach of those Sections of this Agreement may constitute immediate and irreparable injury to the Company.
