**Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers**

On September 8, 2025, Natalia Shuman, President and Chief Executive Officer of Mistras Group (the "Company"), was awarded 25,000 restricted stock units ("RSUs") and options ("Options") to purchase 35,000 shares of the Company's common stock, pursuant to approval of the Compensation Committee of the Company's Board of Directors. The RSUs vest in three equal annual installments on the first three anniversary dates of the September 8, 2025, grant date. Upon vesting, each RSU is converted into one share of Mistras common stock. The terms of the award are consistent with the standard terms of RSU awards for senior officers. The Options have an exercise price of $9.71, the September 8, 2025, closing price on the New York Stock Exchange for the Company's common stock. The Options can be exercised any time on or after September 8, 2026, and expire 10 years after the September 8, 2025, grant date, in each case subject to certain exceptions as to the vesting and expiration in case of termination of employment, death or disability. The Option Agreement and RSU Agreement are filed herewith, and the terms of the agreements are incorporated herein by reference.

The Compensation Committee granted Ms. Shuman these awards at this strategic time for the Company because the Board felt that the CEO should have stock ownership to ensure alignment with our shareholders to promote a vested interest in the Company's long-term performance. Ms. Shuman was not granted any equity upon commencing her employment and now that she has been in this key role for 8 months, the Board and the Compensation Committee determined that these awards were warranted.

The minimum required withholding obligations may be settled with the Shares.

This Award Agreement may not be amended except by means of a writing signed by the Company and the Participant, and, for the avoidance of doubt, if any provision of the Plan that is incorporated by reference herein and applicable to the Option is amended, and such amendment would adversely affect the Participant's interest, then such amended provision shall not be given effect hereunder unless reflected in a writing signed by the Company and the Participant. This Award Agreement is governed by the internal substantive laws but not the choice of law rules of the State of Delaware.

Consistent with Article 3 of the Plan, it is expressly understood that the Committee is authorized to administer, construe, and make all determinations necessary or appropriate to the administration of the Option and this Award Agreement, all of which shall be binding upon the Participant and his successors.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9.&nbsp;&nbsp;&nbsp;&nbsp;<u>Successors</u>. This Agreement shall be binding upon, and inure to the benefit of, any successor or successors of the Company, the Participant and any beneficiary of the Participant.

Except as otherwise provided herein or the Plan, the Units will vest in three (3) equal annual installments, with 1/3 of the Units vesting on each of the dates set forth above.

Unless the Committee, acting in its sole and absolute discretion, determines otherwise, upon the termination of your employment and other service with the Company ("<u>Termination of Employment</u>"), you will forfeit all right, title and interest in the unvested RSUs, unless your Termination of Employment is as a result of (i) your death or termination by the Company on account of your Disability, in which case Section 4 below shall control, (ii) termination by the Company other than for Cause, death or Disability or you resign for Good Reason, in which case Section 5 below shall control, or (iii) as expressly set forth in the Plan, such as in connection with a Change in Control.

Upon Termination of Employment by the Company following your Disability (as defined in your Employment Agreement) or death, all unvested RSUs shall vest and, in the case of your death, the shares represented by such RSUs shall be distributed to your heirs.

You may not sell, assign, transfer, pledge, hedge, hypothecate, encumber or dispose of in any way (whether by operation of law or otherwise) any unvested RSUs, and unvested RSUs shall not be subject to execution, attachment or similar process. Any attempt by you or any other person claiming against, through or under you to cause unvested RSUs to be transferred or assigned in any manner and for any purpose not permitted hereunder or under the Plan shall be null and void and without effect upon the Company, you or any other person.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.&nbsp;&nbsp;&nbsp;&nbsp;<u>No Ownership of Stock; No Dividends or Voting Rights</u>. The RSUs do not represent shares of the Company's common stock, and no dividends or other distributions will be payable on unvested RSUs, and you will not have any voting rights with respect to the unvested RSUs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8.&nbsp;&nbsp;&nbsp;&nbsp;<u>Issuance of Shares Upon Vesting</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10.&nbsp;&nbsp;&nbsp;&nbsp;<u>Provisions of the Plan and the Committee's Authority Control</u>. This certificate is subject to all the terms, conditions and provisions of the Plan, and to the rules, regulations and interpretations as may be established or made by the Committee acting within the scope of its authority and responsibility under the Plan.
