EMPLOYMENT AGREEMENT

This Employment Agreement (the “Agreement”) is entered into on December 31, 2024 between Mistras Group, Inc., a Delaware corporation (such entity or its successor, the “Company”), and Manny N. Stamatakis (“Executive”) and the Agreement shall become effective on January 1, 2025 (the “Effective Date”).

WHEREAS, Executive is currently employed by the Company as interim President and Chief Executive Officer of the Company under an agreement dated October 9, 2023 (“2023 Letter Agreement”) and serves as Chairman of Board of Directors of the Company (the “Board”); and

WHEREAS, effective as of the Effective Date, this Agreement sets forth the terms and conditions of the Company’s continued employment of Executive as an employee of the Company and appointment of Executive in the position as Executive Chairman of the Board.

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound hereby, the parties agree as follows:

1.    Employment. The Company shall employ Executive as an employee of the Company and appoint Executive to the position of Executive Chairman, upon the terms and conditions set forth in this Agreement.

2.    Term. Executive’s employment and appointment pursuant to this Agreement will commence on the Effective Date and will continue until terminated in accordance with Section 10 hereof.

3.    Position and Duties.

(a)Executive shall serve as the Executive Chairman of the Company, will report to the Company’s Board of Directors (the “Board”), will carry out such duties and responsibilities as are customarily performed by persons in Executive’s position generally for public companies within the industry, including, but not limited to: the primary responsibility to manage the affairs of the Board; the primary responsibility to manage and direct strategic planning, merger, acquisition, and disposition activities and margin expansion activities of the Company; in coordination with the Board, the reporting accountability for the Company’s Chief Executive Officer (the “CEO”); and the cultivation of external partnerships, alliances, and relationships which benefit the Company, including with investment banks.

(b)Executive is currently serving as a member and Chairman of the Board, and at the annual meeting of shareholders to be held in calendar year 2025, Executive shall be nominated for re-election as a member of the Board, and, upon election to the Board, Executive shall be re-appointed as Chairman of the Board and each annual meeting of shareholders thereafter while

employed hereunder, Executive shall be nominated for re-election as a member of the Board, and, upon election to the Board, Executive shall be re-appointed as Chairman of the Board.

(c)Executive agrees to devote his best efforts to the performance of his duties and responsibility hereunder. However, the Company acknowledges that Executive has other business and non-profit commitments and agrees that Executive may continue to devote a portion of his business time to those other activities, so long as they do not conflict with his duties hereunder.

4.    Company Policies. Executive will comply with Company policies regarding ethics, personal conduct, stock ownership, securities trading, compensation claw backs, and hedging and pledging of securities.

5.    Place of Performance. Executive may perform Executive’s duties at any location. While employed by the Company, the Company will provide Executive with such computer and other electronic equipment and services as are reasonably required to enable Executive to tend to the business of the Company. During Executive’s employment with the Company, the Company shall hire for Executive with Executive’s approval a direct report, full-time business analyst employee with at least five years relevant experience and at a compensation level commensurate with similar positions with the Company.

6.    Salary. The Company will pay Executive a salary (the “Base Salary”) at an initial annual rate of $725,000, payable in accordance with the Company’s standard payroll schedule and subject to applicable deductions and withholdings. The amount of the Base Salary shall be reviewed on an annual basis and may be increased from time to time by the Board or the Compensation Committee of the Board (the “Compensation Committee”). During Executive’s employment with the Company pursuant to this Agreement, Executive shall not be eligible to receive any fees or stock awards generally payable to members of the Board for their service as members of the Board, by reason of Executive’s service as a member of the Board, as Chairman of the Board, or as a member of any Committee of the Board; provided that equity-based awards previously granted to Executive will remain in effect in accordance with their terms.

7.    Annual Incentive Awards.

(d)(a)    For each calendar year of Executive’s employment hereunder (beginning with the 2025 calendar year), Executive will have the opportunity to earn an annual incentive award under the Company’s “executive annual incentive plan” (sometimes referred to as the “bonus plan”) applicable to senior executives generally, with Executive’s annual incentive target opportunity amount for each calendar year to be 100% of Base Salary (the “Target Bonus Opportunity”) and with the actual incentive award ranging from 0% to 200% of target based on actual performance results. Any annual incentive award that is earned by Executive will be payable consistent with the Company’s regular payroll practices applicable to annual incentive awards for senior executives generally, but in no event will it be paid later than March 15 of the calendar year that immediately follows the calendar year to which the annual incentive award relates. The actual amount that will be earned will depend upon the extent to which performance targets established by the Compensation Committee under the bonus plan are or are not achieved. Except as otherwise expressly provided in Section 11(b), payment of any otherwise earned

annual incentive award will be conditioned on Executive’s continued employment with the Company through the end of the calendar year for which such payment was earned.

(e)(b)    Nothing in this Agreement shall affect Executive’s entitlement to an annual incentive bonus for 2024 as provided in paragraph 3 of the 2023 Letter Agreement.

8.    Long-Term Equity Incentive Grants. For each calendar year of the Executive’s employment hereunder, Executive will be eligible to receive a grant of performance-based equity at the target opportunity amount of 200% of Base Salary, with the actual incentive award ranging from 0% to 200% of target based on actual performance results, which, as of the Effective Date, is contemplated to be in the form of performance-based Restricted Stock Unit Awards (“Performance-Based RSUs”) under the Company’s Long-Term Incentive Plan as in effect from time to time. The terms of each such equity award will be determined by the administrator of the applicable equity plan and memorialized in a separate award agreement. Upon termination of Executive’s employment under this Agreement for any reason other than for “Cause,” the service condition with respect such outstanding unvested Performance-Based RSUs shall be deemed satisfied in full upon such termination and will be paid out in accordance with the formula in Section 11(b)(iii).

9.    Benefits; Business Expenses.

(a)    Executive shall be entitled to participate in Company benefit plans that are generally available to the CEO and other executive-level employees of the Company, in accordance with and subject to the terms and conditions of such plans, as in effect from time to time. Notwithstanding the foregoing, Executive will not participate in the Company’s Executive Severance Plan or any other severance plan, policy or arrangement maintained by the Company or its affiliates (other than the terms of Section 11(b) below).

(f)(b)    Company shall reimburse you for all travel, entertainment and other expenses reasonably incurred or paid by you in connection with, or related to, the performance of your duties and responsibilities to the Company.

10.    Termination.

(g)(a)    Executive’s employment hereunder shall terminate on the earliest of: (i) on the date set forth in a written notice to Executive from the Board that Executive’s employment with the Company has been or will be terminated, (ii) on the date not less than thirty (30) days following written notice from Executive to the Board that Executive is resigning from the Company, (iii) on the date of Executive’s death, or (iv) on the date set forth in a written notice to Executive from the Board that Executive’s employment is terminated on account of Executive’s Disability (as defined in Section 14). Notwithstanding the foregoing, in the event that Executive gives notice of termination to the Board, the Board may unilaterally accelerate the

date of termination and such acceleration shall not constitute a termination by the Board for purposes of this Agreement.

(h)(b)    Upon cessation of Executive’s employment for any reason, unless otherwise consented to in writing by the Board, Executive will resign immediately from any and all officer, director and other positions Executive then holds with the Company and its affiliates and agrees to execute such documents as may be requested by the Company to confirm that resignation.

(i)(c)    Upon any cessation of Executive’s employment with the Company, Executive will be entitled only to such compensation and benefits as described in Section 11 below.

(j)(d)    Executive agrees that, following any cessation of Executive’s employment and subject to reimbursement of Executive’s reasonable expenses, Executive will cooperate with the Company and its counsel with respect to any matter (including litigation, investigations, or governmental proceedings) in which Executive was in any way involved during Executive’s employment with the Company. Executive agrees to render such cooperation in a timely manner on reasonable notice from the Company, provided the Company exercises reasonable efforts to limit and schedule the need for Executive’s cooperation so as not to materially interfere with Executive’s other professional obligations.

(k)(e)    Executive agrees that, upon any cessation of Executive’s employment, Executive will deliver to the Company (and will not retain in Executive’s possession or control, or deliver to anyone else) all property and equity of the Company, including without limitation (i) all keys, books, records, access cards, credit cards and identification, and (ii) all other Company materials (and copies thereof), including any Company records, data, notes, reports, proposals, lists or correspondence; provided that Executive may retain his Company supplied laptop computer after the removal of all Company data and files.

11.    Rights Upon Termination.

(l)(a)    Termination without Cause, Death, Disability, or Resignation for Good Reason. If Executive’s employment by the Company ceases due to a termination by the Board without Cause (as defined in Section 14), Executive’s death or Disability, or a resignation by Executive for Good Reason (as defined in Section 14):

(i)(i)    the Company shall pay to Executive all accrued and unpaid Base Salary through the date of such cessation of employment at the time such Base Salary would otherwise be paid according to the Company’s usual payroll practices;

(ii)(ii)    the Company shall pay to Executive any business expenses that were incurred prior to the date of such cessation of employment but not reimbursed and that are otherwise eligible for reimbursement, within 30 days following Executive’s termination of employment;

(iii)(iii)    to the extent then unpaid, the Company shall pay to Executive the annual incentive award (if any) earned with respect to the calendar year ended on or immediately prior to the date of such cessation of employment, paid at the time such bonus would normally be paid to Executive as provided in Section 7(a); and

(iv)(iv)     any vested benefits under any Company benefit plan in which Executive participated and any other benefits for which Executive is entitled to from the Company for periods after cessation of employment, in each case payable as provided under the applicable plan.

(m)(b)    Termination without Cause or Resignation for Good Reason. In addition to the payments set forth in subparagraph (a), if Executive’s employment by the Company ceases due to a termination by the Board without Cause or a resignation by Executive for Good Reason, the Executive shall be entitled to the following severance benefits:

(i)a total of 200% of the Base Salary as in effect immediately prior to such cessation of employment (or, if such cessation is due to the Good Reason described in clause (i) of that definition, 200% of the Base Salary in effect immediately prior to such material diminution), which amount will be paid in a lump sum on the 35th day following such cessation of employment (the “Settlement Date”); provided, however, if Executive’s employment by the Company ceases due to a termination by the Board without Cause or a resignation by Executive for Good Reason upon or following a Change in Control, Executive shall not receive the payment described in this subsection 11(b)(i);

(ii)a lump sum cash payment equal to a pro rata portion of the annual incentive award, at the higher of the Target Bonus Opportunity or the actual award that Executive would have earned for the calendar year of Executive’s termination based on actual performance results for such year (the “Terminal Award”). The pro-rated portion of the Terminal Award shall be determined by multiplying the Terminal Award by a fraction, the numerator of which is the number of days during which Executive was employed by the Company in the calendar year of Executive’s termination of employment and the denominator of which is three hundred sixty-five (365). Any payment due under this subsection shall be paid at the time that an annual bonus would normally be paid to Executive for such year, as provided in Section 7(a) (or if later, on the Settlement Date);

(iii)Executive will remain eligible to earn a pro-rata portion of any Performance-Based RSUs outstanding and subject to an open performance period as of the date of his termination. For each such award, the Performance-Based RSUs earned under this paragraph will be determined by multiplying (A) the number of such RSUs that would otherwise have been earned (but for Executive’s termination), based on actual performance results through the end of the applicable performance period, by (B) a fraction, the numerator of which is the number of days Executive was employed by the Company in the applicable performance period, and the denominator of which is the total number of days in the applicable performance period. Any Performance-Based RSUs earned under this paragraph will be immediately vested and paid out following the end of the performance period for such Performance-Based RSU; and

(iv)Executive will vest in any outstanding (A) time-vested stock options, and (B) Performance-Based RSUs earned on or prior to the date of Executive’s termination of employment, in each case to the extent such awards were not then otherwise vested.

(v)Except as and solely to the extent otherwise provided in this Section 11(a) and (b), all compensation and benefits will cease at the time of Executive’s cessation of employment and the Company will have no further liability or obligation by reason of such cessation of employment. The payments and benefits described in this Section 11(a) and (b) are in lieu of, and are not in addition to, any other severance plans, policies or arrangements maintained by the Company, including but not limited to severance plans applicable to other Company executives. Notwithstanding any other provision of this Agreement, the payments and benefits described in Section 11(b) are conditioned on Executive’s execution and delivery to the Company and the expiration of all applicable statutory revocation periods, by the 30th day following the effective date of Executive’s cessation of employment, of a general release of claims against the Company and its affiliates in substantially the form attached hereto as Exhibit A (but subject to such revisions as may be required, in the judgment of Company counsel, to reflect then applicable legal or regulatory requirements) (the “Release”).

(c)    Other Terminations. If Executive’s employment with the Company ceases for any reason other than as described in Sections 11(a) and (b) above (including but not limited to termination by the Board for Cause or resignation by Executive without Good Reason), then the Company will provide to Executive:

(i)    the payment of accrued and unpaid Base Salary through the date of such cessation of employment, paid at the time such Base Salary would otherwise be paid according to the Company’s usual payroll practices;

(ii)    payment of any business expenses that were previously incurred but not reimbursed and are otherwise eligible for reimbursement, paid within 30 days following Executive’s termination of employment;

(iii)    to the extent then unpaid, and solely with respect to resignation by Executive without Good Reason, the Company shall pay to Executive the annual incentive award (if any) earned with respect to the calendar year ended on or immediately prior to the date of such cessation of employment, paid at the time such bonus would normally be paid to Executive as provided in Section 7(a); and

(iv)    to the extent not forfeited as a result of termination of Executive’s employment for Cause or resignation by Executive without Good Reason, any vested benefits under any Company benefit plan in which Executive participated and any other benefits for which Executive is entitled to from the Company for periods after cessation of employment, in each case payable as provided under the applicable plan.

Except as otherwise provided by COBRA, all compensation and benefits will cease at the time of such cessation of employment and the Company will have no further liability or obligation by reason of such termination; and, unless otherwise determined by the Committee at or after the time of the grant, all unvested and/or unearned equity and equity-based awards then held by Executive will be forfeited. The foregoing will not be construed to limit Executive’s right to payment or reimbursement for claims incurred prior to the date of such termination under any

insurance contract funding an employee benefit plan or arrangement of the Company in accordance with the terms of such insurance contract.

12.    Section 409A.

(n)(a)    The parties intend for this Agreement to comply with or be exempt from Section 409A of the Code, and all provisions of this Agreement will be interpreted and applied accordingly. Nonetheless, the Company does not guaranty the tax treatment of any compensation payable to Executive.

(o)(b)    Notwithstanding anything to the contrary in this Agreement, to the extent necessary to facilitate compliance with Section 409A of the Code, no portion of the benefits or payments to be made under Section 11 above will be payable until Executive has a “separation from service” from the Company within the meaning of Section 409A of the Code. In addition, to the extent compliance with the requirements of Treas. Reg. § 1.409A-3(i)(2) (or any successor provision) is necessary to avoid the application of an additional tax under Section 409A of the Code to payments due to Executive upon or following Executive’s “separation from service,” then notwithstanding any other provision of this Agreement (or any otherwise applicable plan, policy, agreement or arrangement), any such payments that are otherwise due within six (6) months following Executive’s “separation from service” (taking into account the preceding sentence of this paragraph) will be deferred without interest and paid to Executive in a lump sum immediately following that six (6) month period. This paragraph should not be construed to prevent the application of Treas. Reg. § 1.409A-1(b)(9)(iii) (or any successor provision) to amounts payable hereunder. For purposes of the application of Section 409A of the Code, each payment under this Agreement is a separate payment and each installment payment will be deemed a separate payment.

(p)(c)    Notwithstanding anything in this Agreement to the contrary, to the extent an expense, reimbursement or in-kind benefit provided to Executive pursuant to this Agreement or otherwise constitutes a “deferral of compensation” within the meaning of Section 409A of the Code: (i) the amount of expenses eligible for reimbursement or in-kind benefits provided to Executive during any calendar year will not affect the amount of expenses eligible for reimbursement or in-kind benefits provided to Executive in any other calendar year, (ii) the reimbursements for expenses for which Executive is entitled to be reimbursed shall be made on or before the last day of the calendar year following the calendar year in which the applicable expense is incurred, and (iii) the right to payment or reimbursement or in-kind benefits hereunder may not be liquidated or exchanged for any other benefit.

13.    Section 280G. Notwithstanding any contrary provision of this Agreement (or any plan, policy, agreement or other arrangement covering Executive), if any payment, right or benefit paid, provided or due to Executive, whether pursuant to this Agreement or otherwise (each, a “Payment,” and collectively, the “Total Payments”), would subject Executive to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then the Total Payments will be reduced to the minimum extent necessary to avoid the imposition of the Excise Tax, but only if the amount of such Total Payments, as so reduced, is greater than or equal to the amount of such Total Payments without reduction (in each case, determined by the Company on an after-tax

basis). Any reduction of the Total Payments required by this paragraph will be implemented by determining the Parachute Ratio (as defined below and determined by the Company) for each Payment and then by reducing the Payments in order, beginning with the Payment with the highest Parachute Ratio. For Payments with the same Parachute Ratio, later Payments will be reduced before earlier Payments. For Payments with the same Parachute Ratio and the same time of payment, each Payment will be reduced proportionately. For purposes of this paragraph, “Parachute Ratio” means a fraction, (x) the numerator of which is the value of the applicable Payment, as calculated for purposes of Section 280G of the Code, and (y) the denominator of which is the economic value of the applicable Payment. All determinations pursuant to this paragraph shall be determined by an independent accounting firm engaged by the Company for this purpose.

14.    Certain Definitions. For purposes of this Agreement:

(q)(a)    “Cause” means any of the following: (i) gross misconduct by Executive in connection with the performance of Executive’s duties and responsibilities to the Company, including, without limitation, a breach of fiduciary duties or a misappropriation of funds or property; (ii) the conviction of Executive of any felony; (iii) a material breach by Executive of any agreement with or duty owed to the Company or its affiliates, which breach is not cured within fifteen (15) days after the delivery of written notice thereof; (iv) a material violation by Executive of the Company’s written employment policies, which violation is not cured within fifteen (15) days after the delivery of written notice thereof; or (v) Executive’s material failure to cooperate with a bona fide internal investigation or an investigation by regulatory or law enforcement authorities, after being instructed by the Company to cooperate, or the willful destruction or failure to preserve documents or other materials known to be relevant to such investigation or the inducement of others to fail to cooperate or to produce documents or other materials in connection with such investigation.

(s)(c)    “Code” means the Internal Revenue Code of 1986, as amended.

(t)(d)    “Disability” means a condition entitling Executive to benefits under the Company’s long term disability plan, policy or arrangement; provided, however, that if no such plan, policy or arrangement is then maintained by the Company and applicable to Executive, “Disability” will mean Executive’s inability to perform Executive’s duties under this Agreement due to a mental or physical condition that can be expected to result in death or that can be expected to last (or has already lasted) for a continuous period of 180 days or more, or for 180 days in any 240 consecutive-day period.

(u)(e)    “Good Reason” means: (i) a material diminution in Executive’s authority, duties or responsibilities; (ii) if Executive is not re-elected to and/or appointed as Executive Chairman of the Board in 2025 or thereafter in any year in which Executive is still employed under the Agreement; (iii) a reduction in the Base Salary that exceeds ten percent (10%) of the Base Salary as in effect immediately prior to the reduction (excluding, however, the impact of

across-the-board salary reductions similarly affecting other senior executives of the Company); or (iv) the material breach of this Agreement by the Company; provided, however, that no such event will constitute Good Reason unless (x) Executive provides the Company with written objection to such event within ninety (90) days after the initial occurrence thereof, and (y) such event is not reversed or corrected by the Company within thirty (30) days of its receipt of such written objection, in which case Executive’s employment with the Company shall terminate at Executive’s election at the end of such thirty (30) day cure period.

(v)(a)    Restrictive Covenants. It is agreed and understood by the parties hereto that the Board appointed Executive as Executive Chairman to lead and manage a total reorganization of the Company’s business operations and recruit and recommend named officers in the aftermath of challenges following the COVID-19 pandemic. It is agreed and understood by and between the parties that the Executive Chairman shall not solicit Company customers or employees to engage in a competing business with the Company, compete with the Company, nor disclose confidential information or proprietary intellectual property of the Company following separation of Executive; provided, however, that this Section 15(a) shall not apply if Executive’s employment ceases due to a termination by the Board without Cause or a resignation by Executive for Good Reason.

(w)(b)    Whistleblower Activities. Notwithstanding anything herein to the contrary, Executive understands that this Agreement will not (i) prohibit him from making reports of possible violations of federal law or regulation to any governmental agency or entity in accordance with the provisions of and rules promulgated under Section 21F of the Securities Exchange Act of 1934, as amended, or Section 806 of the Sarbanes-Oxley Act of 2002, or of any other whistleblower protection provisions of federal law or regulation, or (ii) require notification or prior approval by the Company of any such report; provided that, Executive is not authorized to disclose communications with counsel that were made for the purpose of receiving legal advice or that contain legal advice or that are protected by the attorney work product or similar privilege.

16.No Duty to Mitigate. Except as otherwise specifically provided herein, Executive’s entitlement to payments or benefits upon or following the termination of his or her employment will not be subject to mitigation or a duty to mitigate by Executive.

17.No Conflicting Agreements. Executive represents and warrants that Executive is not a party to or otherwise bound by any restrictive covenant or similar agreement that will conflict with, or be violated by, the performance of his duties to the Company or his obligations under this Agreement. Executive will not use or misappropriate any intellectual property, trade secrets or confidential information belonging to any third party.

18.Taxes. All compensation payable to Executive is subject to reduction to reflect applicable withholding and payroll taxes and other deductions required by law. Executive hereby acknowledges that the Company does not have a duty to design its compensation policies in a

manner that minimizes Executive’s tax liabilities, and Executive not make any claim against the Company or its board of directors related to tax liabilities arising from his or her compensation.

19.Counsel and Other Fees. Within 14 days of presentment of an invoice following the Effective Date, the Company will pay directly to Executive’s counsel the actual out-of-pocket costs and expenses, including but not limited to attorneys’ fees, reasonably incurred by Executive in connection with the preparation and negotiation of this Agreement and related matters.

20.Indemnification. In addition to, and without limiting, any and all indemnification rights provided to officers, directors, and/or employees of the Company pursuant to the Company’s Certificate of Incorporation and/or Bylaws, the Company shall indemnify and hold Executive harmless to the maximum extent permitted under applicable law for acts and omissions in Executive’s capacity as an officer, director, and/or employee of the Company. To the fullest extent not prohibited by applicable law and subject to Executive’s execution of any repayment undertaking required by applicable law, expenses incurred by Executive in defending any civil, criminal, administrative or investigative action, suit or proceeding in connection with Executive’s service as an officer, director, and/or employee of the Company shall be paid by the Company in advance of the final disposition of such action, suit or proceeding.

21.Entire Agreement; Assignment; Amendment.

(x)(a)    This Agreement, including the exhibits, schedules and other documents referred to herein, constitutes the final and entire agreement of the parties with respect to the matters covered hereby and supersedes any prior and/or contemporaneous agreements, arrangements discussions, negotiations, representations or understandings (whether written, oral or implied) relating to the subject matter hereof; and, for the avoidance of doubt, Executive confirms there are no agreements, arrangements, discussions, negotiations, representations or understandings between Executive and the Company, or any affiliates of the Company, not referred to herein.

Rules for the Resolution of Employment Disputes then in effect of the American Arbitration Association (“AAA”), by one arbitrator mutually agreed upon by the parties (or, if no agreement can be reached within thirty (30) days after names of potential arbitrators have been proposed by the AAA, then by one arbitrator having relevant experience who is chosen by the AAA).
