C. In the course of performing your duties for us, you are likely to acquire confidential and proprietary information belonging to us, our customers, and our suppliers, develop relationships that are vital to our Business and goodwill, and acquire other important assets in which we have a protectable interest, and you have agreed to the covenants in this Agreement required to protect those assets.

In consideration of the foregoing and the representations, warranties and mutual covenants herein, you and we agree as follows:

1. Employment

The job title and duties referred to in the preceding sentence may be changed by us in our sole discretion at any time. This position will be located at our facilities in Wichita, Kansas. You will devote your full time to this employment.

(b) Employment Period Your employment will commence on the Effective Date, will continue for a period of two years after the Effective Date (the “Initial Term”), and will be automatically extended for successive one-year periods thereafter (each a “Renewal

Term”), unless either of us provides the other with written notice at least ninety (90) days in advance of the expiration of the Initial Term or the then-current Renewal Term, as applicable, that such period will not be so extended (the Initial Term and any Renewal Term are, collectively, the “Employment Period”). In all cases, your employment is subject to earlier termination as provided in this Agreement.

2. Performance

You will devote your best efforts and abilities to faithfully preserve and advance our Business, welfare, and best interests.

Except as otherwise provided herein, for all services to be performed by you in any capacity, including without limitation any services as an officer, director, member of any committee, or any other duties assigned to you, during the Employment Period we will pay or provide you with the following, and you will accept the same, as compensation for your covenants in and performance of your duties under this Agreement:

(a) Base Salary You will be entitled to an annual salary of $400,000.00 (“Base Salary”), which will be paid in accordance with our policies and procedures. The Base Salary may be changed from time to time on a discretionary basis or based upon your and/or our performance or such other factors as we deem appropriate in its sole discretion.

    (b) Signing Bonus – Restricted Stock In consideration of entering into this Agreement, we will grant you units in the amount of $500,000 (the “Bonus Units”) under the Holdings Omnibus Incentive Plan, as amended or restated from time to time or any successor thereto (the “OIP”), subject to the terms and provisions of the OIP and this Section 3(b) and further conditioned upon you being employed on the date the Bonus Units are granted to you pursuant to the appropriate approval.

The number of units to be awarded in connection with the grant of the Bonus Units will be determined in accordance with such methods or conventions as are designated by the Board in connection with approval of the award.

(c) Short-Term Incentive Plan You are eligible to participate in the Spirit AeroSystems Holdings, Inc. Short-Term Incentive Plan (“STIP”), pursuant to and in accordance with the terms and conditions of the STIP and the OIP, each as amended or restated from time to time. Your target STIP award opportunity will be 75% of Base Salary if target performance goals are reached and your maximum STIP award opportunity will be 150% of Base Salary if outstanding performance goals are reached. If target performance goals are not reached, you will be entitled to such incentive compensation, if any, as is otherwise provided by STIP and our policies.

(d) Long-Term Incentive Plan You are eligible to participate in annual awards under the Spirit AeroSystems Holdings, Inc. Fourth Amended and Restated Long-Term Incentive Plan (“LTIP”), as granted by the Holdings Board or its designee pursuant to and in accordance with the terms and conditions of the LTIP and the OIP, each as amended or restated from time to time. Each year of the Initial Term, you will receive an annual LTIP award equal to 100% of Base Salary. In each year of employment following the Initial Term, your participation in the LTIP and award opportunity under the LTIP will be pursuant to and in accordance with the terms and conditions of the LTIP and OIP then in effect. Your annual LTIP awards will be granted at the time and on the terms that we grant annual LTIP awards to our other executives. In addition, you will receive an initial LTIP grant for the 2024 plan year consistent with similarly situated employees and otherwise in accordance with the terms of the award agreement, OIP, and LTIP.

(e) Other Benefit Plans You will also be eligible to participate in other benefit plans, policies, practices, and arrangements in which one or more of our senior executives is eligible to participate from time to time, including without limitation (i) any defined benefit or defined contribution retirement plan, excess or supplementary plan, profit-sharing plan, savings plan, health and dental plan, disability plan, survivor-income and life-insurance plan, executive financial planning program, or other arrangement, or any successors thereto; (ii) any perquisite allowance or reimbursement arrangement the Holdings Board or its designee may adopt; and (iii) such other benefit plans as we may establish or maintain from time to time (collectively “Benefit Plans”). Your entitlement to any other compensation or benefits will be determined in

accordance with the terms and conditions of the Benefit Plans and other applicable programs, practices, and arrangements then in effect.

(f) Holiday and Time Off You will be provided with 12 paid holidays each year and with responsible paid time off in accordance with our policies and practices in effect from time to time.

(i) Expenses During your employment, we will promptly pay or reimburse you for all reasonable out-of-pocket expenses incurred by you in the performance of your duties, in accordance with our policies and procedures then in effect.

The payment or reimbursement of expenses described in this Section 3 are not intended to provide for the deferral of compensation within the meaning of Code Section 409A because all such expenses are to be paid or reimbursed currently and/or will be tax-free. To the extent such expenses are deemed to provide for the deferral of compensation within the meaning of Code Section 409A, they are intended to meet the requirements of a specified date or a fixed schedule of payments, and this reimbursement provision will be interpreted and applied in a manner consistent with such requirements. The right to payment of, or reimbursement for, expenses is not subject to liquidation or exchange for any other benefit.

4. Restrictions

(b) Reasonableness In view of the foregoing and in consideration of the remuneration to be paid to you, you agree that it is reasonable and necessary for the protection of our Business and goodwill that you undertake the covenants in this Section 4 regarding your conduct during and subsequent to your employment by us, and acknowledge we will suffer irreparable injury if you engage in any conduct prohibited by this Section 4.

(e) Confidentiality

(i) Confidential Information For purposes of this Agreement, “Confidential Information” means any information (whether in written, oral, graphic, schematic, demonstration, or electronic format, whether or not specifically marked or identified as confidential, and whether obtained by you before or after the Effective Date), not otherwise publicly disclosed by Spirit, regarding (without limitation) Spirit, its Business, customers, suppliers, business partners, prospects, contacts, contractual arrangements, discussions, negotiations, evaluations, labor negotiations, bids, proposals, aircraft programs, costs, pricing, financial condition or results, plans, strategies, governmental relations, projections, analyses, methods, processes, models, tooling, know-how, trade secrets, discoveries, research, developments, inventions, engineering, technology, proprietary information, intellectual property, designs, computer software, intelligence, legal or regulatory compliance, accounting

decisions, opportunities, challenges, and any other information of a confidential or proprietary nature. Notwithstanding the foregoing, Confidential Information will not include any information that (A) you are required to disclose by the order of a court or administrative agency, subpoena, or other legal or administrative demand, so long as (1) you give us written notice and an opportunity to contest or seek confidential treatment of such disclosure; and (2) you fully cooperate at our expense with any such contest or confidential treatment request; (B) has been otherwise publicly disclosed or made publicly available by Spirit; or (C) was obtained by you in good faith after your employment with us ended from a source that was under no obligation of confidentiality to Spirit or any customer or supplier.

(ii) Non-Use and Non-Disclosure Without our express written consent, you will not at any time (whether during the Employment Period or after any termination of your employment for any reason) use for any purpose (other than for our exclusive benefit) or disclose to any Person (except at our direction) any Confidential Information.

            (iii) Permitted Disclosure Notwithstanding any other provision of this Agreement, and specifically paragraph (ii) above, nothing in this Agreement is intended to, or does, preclude you from (A) contacting, reporting to, responding to an inquiry from, filing a charge or complaint with, communicating with, or otherwise participating in an investigation conducted by a federal, state, or local governmental agency, commission, or regulatory body; (B) giving truthful testimony or making statements under oath in response to a subpoena or other valid legal process or in any legal proceeding; (C) otherwise making truthful statements as required by law or valid legal process; (D) engaging in any concerted or other legally protected activities; or (E) disclosing a trade secret in confidence to a governmental official, directly or indirectly, or to an attorney, if the disclosure is made solely for the purpose of reporting or investigating a suspected violation of law. 

Furthermore, you understand that you will not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that (i) is made (A) in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney, and (B) solely for the purpose of reporting or investigating a suspected violation of law; or (ii) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal.  You likewise understand that, if you file a lawsuit for retaliation by us for reporting a suspected violation of law, you may disclose our trade secret(s) to your attorney and use the trade secret information in the court proceeding, if you (i) file any document containing the trade secret under seal; and (ii) do not disclose the trade secret, except pursuant to court order.

(f) Effect of Breach You agree that a breach of this Section 4 cannot adequately be compensated by money damages and, therefore, we will be entitled, in addition to any other right or remedy available to us (including, but not limited, to an action for damages, accounting, or disgorgement of profit), to an injunction restraining such breach or a threatened breach and to specific performance of such provisions, and you consent to the issuance of such injunction and

the ordering of specific performance without the requirement for us to post a bond or other security or to prove lack of an adequate remedy at law.

(g) Other Rights Preserved Nothing in this Section 4 eliminates or diminishes rights we may have with respect to the subject matter hereof under other agreements, our governing documents or statutes, or provisions of law (including but not limited to common law and the Uniform Trade Secrets Act), equity, or otherwise. Without limiting the foregoing, this Section 4 does not limit any rights we may have under any applicable policies or any agreements with you regarding Confidential Information.

5. Termination Your employment with us will terminate upon the following circumstances:

(a) Without Cause At any time at the election of either you or us for any reason or no reason, without Cause, but subject to the provisions of this Agreement. It is expressly understood that your employment is strictly “at will.”

(b) Cause At any time at our election for Cause.

“Cause” for purposes of this Agreement means (i) your commission of a material breach of this Agreement; acts involving fraud, material and intentional dishonesty; material and intentional unauthorized disclosure of Confidential Information; the commission of a felony or other crime involving moral turpitude; or acts deemed to be unaligned with Spirit values or material violation of Spirit policies; (ii) direct and deliberate acts constituting a material breach of your duty of loyalty to Spirit; (iii) your refusal or material failure (other than by reason of your serious physical or mental illness, injury, or medical condition) to perform your job duties and responsibilities, including, but not limited to, any duties or responsibilities reasonably assigned to you by the Board, if such refusal or failure is not remedied within thirty (30) days after you receive written notice thereof from the Board; (iv) your material underperformance as determined by Spirit leadership; or (v) your inability to obtain and maintain the appropriate level of United States security clearance if required for your position.

(c) Death or Disability Your death or your inability to perform the services required of you for a period of 180 days during any twelve-month period (“Disability”).

6. Effect of Termination

(a) General Rule If your employment terminates for any reason other than as described in Section 6(b) below, we will pay your compensation only through the last day of employment, and, except as otherwise expressly provided in this Agreement or the STIP, the LTIP, the Deferred Compensation Plan (“DCP”), or any Benefit Plan, we will have no further obligation to you.

(b) Termination Without Cause If your employment is terminated by us without Cause at any time during the Initial Term of the Agreement, then for so long as you comply with your continuing obligations under Section 4 we will (i) pay your monthly Base Salary in effect immediately before termination of your employment for a period of one (1) year and (ii) pay the cost of COBRA medical and dental benefits coverage for a period of six (6) months.

To receive the benefits described in this Section 6(b), you will be required to sign a general release of claims in a form we deem acceptable. The release must be provided, and any revocation period must have expired, not later than 60 days after termination of employment. If the foregoing conditions are satisfied then, except as provided below, payment of salary continuation and other benefits will begin 60 days after termination of employment.

Notwithstanding any contrary provision of this Section 6(b), if you are a Specified Employee (as defined in Section 409A of the Code) at the time employment terminates, the payments described in Section 6(b) will, to the extent such amounts are deferred compensation within the meaning of Code Section 409A, be delayed until the date that is the earlier of (i) six (6) months after your termination of employment, or (ii) the date of your death, and upon reaching that date, all amounts that would have been paid during the six-month delay period, plus interest thereon at the prime rate (as published in the Wall Street Journal) from the date the payment would have been made but for this paragraph to the date of payment, will be paid in a single lump sum, and all remaining amounts will be paid in equal monthly payments for the remainder of the Salary Continuation Period.

Except as otherwise expressly provided in this Agreement or in any Benefit Plan, we will have no further obligation to you upon your termination for any reason.

(c) Disability or Death If your employment terminates due to Disability or death, we will pay your monthly Base Salary only through the date of termination.

(d) Your Post-Termination Obligations On termination of employment for any reason, (i) you will (if applicable) resign as of the date of such termination as a director and officer of Spirit and its affiliates and as a fiduciary of any of Spirit’s or its affiliates’ benefit plans, (ii) you will promptly execute and deliver upon such termination any document reasonably required by Spirit or an affiliate to evidence the foregoing resignations, (iii) you will immediately deliver to us all Confidential Information, all copies and embodiments thereof, and all records, notes, worksheets, schematics, customer lists, supplier lists, memoranda, computer files and storage devices, analyses and derivative works based thereon or which relate in any way thereto, and (iv) you will pay to us any amounts due and owing by you as specified in this Agreement.

(e) Survival of Provisions Your obligations under Sections 4 through 9 of this Agreement will survive the expiration or termination of your employment for any reason.

7. Representations and Warranties You represent and warrant to us that:

(a) No Conflicts To the best of your knowledge, you are under no duty (whether contractual, fiduciary or otherwise) that would prevent, restrict or limit you from entering into this Agreement and fully performing all duties and services for us, and the performance of such duties and services will not conflict with any other agreement, policy or obligation by which you are bound.

(b) No Hardship Your experience and/or abilities are such that observance of the covenants in this Agreement will not cause you any undue hardship and will not unreasonably interfere with your ability to earn a livelihood.

8. Clawback Right You acknowledge that certain amounts paid under this Agreement or the Benefit Plans described herein are subject to any Spirit policy on the recovery of compensation (i.e., a so-called “clawback policy”), as it exists now or as later adopted, and as thereafter amended from time to time.

9. Mediation

(a) General Obligation to Mediate Except as provided in this Agreement, prior to initiating any legal action, the parties agree to submit all unsettled claims, disputes, controversies, and other matters in question between them arising out of or relating to this Agreement (including but not limited to any claim that this Agreement or any of its provisions is invalid, illegal, or otherwise voidable or void) or the dealings or relationship between them (“Disputes”) to mediation in Wichita, Kansas, in accordance with the Commercial Mediation Rules of the American Arbitration Association currently in effect. The mediation will be private, confidential, voluntary, and nonbinding. Either party may withdraw from the mediation at any time before signing a settlement agreement by giving written notice to the other party and the mediator. The mediator will be neutral and impartial. The mediator will be disqualified as a witness, consultant, expert, or counsel for either party with respect to the matters in Dispute and any related matters. Each party will pay its respective attorneys’ fees and other costs associated with the mediation, and each party will equally bear the costs and fees of the mediator. If a Dispute cannot be resolved through mediation within 90 days of its submission to mediation, the parties may proceed with legal action.

(b) Confidentiality The parties agree that they will not disclose, or permit those acting on their respective behalf to disclose, any aspect of the proceedings under Section 9(a), including but not limited to the resolution or the existence or amount of any award, to any Person, unless divulged (i) to an agency of the federal or state government; (ii) pursuant to a court or administrative order; (iii) pursuant to a requirement of law; (iv) pursuant to prior written consent of the parties; (v) pursuant to a legal proceeding to enforce a settlement agreement or arbitration award; or (vi) by Spirit, to the extent required under federal securities laws and regulations. This provision does not prohibit the parties’ disclosure of the terms of any settlement to their attorney(s), accountant(s), financial advisor(s), or family members, so long as such persons first agree to comply with the provisions of this Section 9(b).

(c) Injunctions Notwithstanding anything to the contrary in this Section, the parties will have the right in a proper case to obtain temporary restraining orders and temporary or preliminary injunctive relief from a court of competent jurisdiction.

(b) Successors Neither this Agreement nor any right or interest herein will be assignable or transferable (whether by pledge, grant of a security interest or otherwise) by you or your beneficiaries or legal representatives, except by will, the laws of descent and distribution, or inter vivos revocable living grantor trust as your beneficiaries, and any other purported assignment will be void. This Agreement will be binding upon and will inure to the benefit of Spirit, its successors and assigns, and will be binding on you and your heirs, beneficiaries, and legal and personal representatives.

(c) Waiver, Modification, and Interpretation No provisions of this Agreement may be modified, waived, or discharged except by written instrument signed by you and an appropriate officer of Spirit empowered to sign the same by our board of directors or the Holdings Board. No waiver by either party at any time of any breach by the other party of, or compliance with, any condition or provision of this Agreement to be performed by the other party will be deemed a waiver of similar or dissimilar provisions or conditions at the same time or at any prior or subsequent time.

(d) Interpretation The validity, interpretation, construction, and performance of this Agreement will be governed by the laws of the State of Kansas, except that the corporate law of the State of Delaware will govern issues related to the issuance of common stock. Any action

brought to enforce or interpret this Agreement will be maintained exclusively in the state and federal courts located in Wichita, Kansas.

(e) Headings The headings in this Agreement are for reference purposes only and will not in any way affect the meaning or interpretation of any provision of this Agreement. No provision of this Agreement will be interpreted for or against either party on the basis that such party was the draftsman of such provision, and no presumption or burden of proof will arise disfavoring or favoring either party by virtue of the authorship of any provision of this Agreement.

(f) Counterparts We and you may execute this Agreement in counterparts, each of which will be deemed an original and both of which will constitute a single instrument. In proving this Agreement, it will not be necessary to produce or account for more than one such counterpart.

(g) Invalidity of Provisions If a court of competent jurisdiction declares that any provision of this Agreement is invalid, illegal, or unenforceable in any respect, then in lieu of such illegal, invalid, or unenforceable provision the court may add as a part of this Agreement a legal, valid, and enforceable provision as similar in terms to such illegal, invalid, or unenforceable provision as is possible. If such court cannot so substitute or declines to so substitute for such illegal, invalid, or unenforceable provision (i) such provision will be fully severable; (ii) this Agreement will be construed and enforced as if such illegal, invalid, or unenforceable provision had never comprised a part hereof; and (iii) the remaining provisions of this Agreement will continue in full force and effect and not be affected by the illegal, invalid, or unenforceable provision or by its severance herefrom. The covenants in this Agreement will each be construed to be a separate agreement independent of any other provision of this Agreement, and the existence of any claim or cause of action of yours against us, predicated on this Agreement or otherwise, will not constitute a defense to the enforcement by us of any covenants in this Agreement.

(h) Entire Agreement This Agreement (together with the documents expressly referred to herein) constitutes the entire agreement between the parties, supersedes in all respects any prior agreement between you and us, and may not be changed except by written instrument duly executed by you and us in the same manner as this Agreement.

(i) Compliance with Code Section 409A The amounts payable to you after separation from service under Section 6(b) (if any) are intended to be exempt from the definition of “deferred compensation” for purposes of Code Section 409A as amounts payable only in the event of involuntary termination without Cause. To the extent any such amounts constitute “deferred compensation” for purposes of Code Section 409A, then those amounts will be paid to you in equal monthly installments, and payment of such amounts may not be accelerated. This Agreement is intended to comply with, and will be interpreted and construed in accordance with and in a manner that complies with, the requirements of Code Section 409A. To the extent that any provision in this Agreement is ambiguous as to its compliance with Section 409A or to the

extent any provision in this Agreement must be modified to comply with Section 409A (including, without limitation, Treasury Regulation 1.409A-3(c)), such provision will be read, or will be modified (with the mutual consent of the parties, which consent will not be unreasonably withheld), as the case may be, in such a manner so that all payments due under this Agreement will comply with Section 409A. For purposes of Section 409A, each payment made under this Agreement will be treated as a separate payment. In no event may you, directly or indirectly, designate the calendar year of payment.
