(the “Company”) for the purpose of increasing the number of shares of its common stock, $0.01 par value per share, that may be issued under the Mistras Group, Inc. 2016 Long-Term Incentive Plan, amended and restated as of March 27, 2024 (the “Plan”) by 1,300,000 shares, to a total of 6,200,000 shares, plus up to an additional 500,000 shares to allow for the recycling of shares back into the Plan in connection with share withholding or expirations, cancellations, forfeitures, or similar events with respect to Plan awards. The Company previously filed with the Securities and Exchange Commission (the “SEC”) three registration statements on Form S-8 (File No. 333-266573, File No. 333-217047 and File No. 333-254369) with respect to the Plan (the “Prior Registration Statements”). This Registration Statement relates to the securities of the same class as that to which the Prior Registration Statements relate and is submitted in accordance with General Instruction E to Form S-8 regarding registration of additional securities. In accordance with such instruction, except as otherwise set forth below, the contents of the Prior Registration Statements relating to the Plan are incorporated herein by reference.

Item 1.    Plan Information.
This Registration Statement omits the information specified in Part I of Form S-8, as permitted by Rule 428 under the Securities Act of 1933, as amended (the “Securities Act”), which shall instead be delivered to participants in the Plan as provided by Rule 428(b)(1) under the Securities Act. Such documents will not be filed with the SEC as part of this Registration Statement or as prospectuses or prospectus supplements pursuant to Rule 424(b) under the Securities Act.

Item 9.    Undertakings.
(a)    The Company hereby undertakes:
(1)    To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:
i.To include any prospectus required by Section 10(a)(3) of the Securities Act;
ii.To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing,



any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Filing Fee Table” or “Calculation of Registration Fee” table, as applicable, in the effective Registration Statement; and
iii.To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement;
provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the Registration Statement is on Form S-8, and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the Company pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the Registration Statement.
(2)    That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(3)    To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
(b)    The undersigned Company hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Company’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(c)    Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Company pursuant to applicable law, the Company’s articles of incorporation or bylaws, as such may be amended from time to time, the Company’s indemnification agreements or otherwise, the Company has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Company of expenses incurred or paid by a director, officer or controlling person of the Company in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Company will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

Re:  Mistras Group, Inc. Registration Statement on Form S-8
 
Ladies and Gentlemen:
 
I am the Executive Vice President, General Counsel and Secretary of Mistras Group, Inc., a Delaware corporation (the “Company”), and have acted as counsel to the Company in connection with the preparation and filing of a Registration Statement on Form S-8 (the “Registration Statement”) under the Securities Act of 1933 (the “Act”), for the registration of an additional 1,800,000 shares of common stock, par value $0.01 per share, of the Company (the “Shares”) that may be issued under the Mistras Group, Inc. 2016 Long-Term Incentive Plan, Amended and Restated as of March 27, 2024 (the “Plan”).
 
In rendering the opinion set forth herein, I have examined and relied on originals or copies, certified or otherwise identified to my satisfaction, the following: (i) the Plan; (ii) the Registration Statement in the form to be filed under the Act; (iii) the Second Amended and Restated Certificate of Incorporation, as amended to date and currently in effect; (iv) the Amended and Restated By-Laws of the Company, as amended to date and currently in effect; (v) certain resolutions of the Board of Directors of the Company (the “Board”) relating to the Plan, the filing of the Registration Statement and certain related matters; (vi) the certificate and report of the inspector of election at the Company’s annual meeting of shareholders held on May 14, 2024; and (vii) such other documents as I have deemed necessary or appropriate as a basis for the opinion set forth below.

In my examination, I have assumed the legal capacity of all natural persons, the genuineness of all signatures, the authenticity of all documents submitted to me as originals, the conformity to original documents of all documents submitted to me as certified, conformed copies and the authenticity of the originals of such latter documents.
 
Based upon the foregoing, I am of the opinion that the Shares to be issued under the Plan have been duly authorized and, when issued, delivered and paid for in accordance with the terms of the Plan and the agreements that accompany the Plan, the Shares will be validly issued, fully paid and nonassessable.
 
I am a member of the bar of the State of New Jersey and I do not express any opinion as to the laws of any other jurisdiction other than the Delaware General Corporation Law.
 
I hereby consent to the filing of this opinion with the U.S. Securities and Exchange Commission as an exhibit to the Registration Statement.
 
Very truly yours,
