Re: Position as Interim President and CEO

Dear Jim:
This letter (this “CEO Letter Agreement”) is effective as of November 29, 2024 and will confirm the terms of the agreement offered to you by DMC Global Inc. (the “Company”) with respect to your role as the Company’s Interim President and Chief Executive Officer, which will be in addition to your role as Executive Chairman.
Position as Executive Chairman. As you know, you are a member of the Board of Directors of the Company (the “Board”) and are currently serving as the Company’s Executive Chairman in accordance with the terms of the letter agreement entered into by and between you and the Company dated effective as of October 16, 2024 (the “Executive Chairman Agreement”). Your position as Executive Chairman will continue pursuant to the terms and conditions of the Executive Chairman Agreement except as modified herein.
Position as Interim President and CEO. Should you accept this offer, you will serve as (Interim) President and Chief Executive Officer (“Interim CEO”) of the Company, reporting to the Board. Your position as Interim CEO will commence effective upon November 29, 2024 and continue through June 30, 2025 (the “Term”), unless such period is modified by mutual written agreement of the parties. However, the Company acknowledges that most of the critical transition services outlined in Attachment A hereto commenced and have been administered by you since your appointment as Executive Chairman.
Base Salary. For the period of time during which you serve both as Executive Chairman and as Interim CEO, you have agreed to maintain your base salary at the level agreed upon in the Executive Chairman Agreement.
Strategic Transition Services. So long as you remain continuously employed as Interim CEO, you will be eligible for certain cash payments in the aggregate target amount of $2,000,000 (the “Target Amount”).
The actual amount of such cash payments will be determined based on (as applicable) completion of targets (“Target Goals”) or performance of certain ongoing transition services (“Transition Services”) as set forth on Attachment A to this CEO Letter. These will

be reviewed on a bimonthly basis by the Compensation Committee commencing in December 2024 (each review, a “Progress Review”).
Payments for completed Target Goals shall be made promptly after each Progress Review, and payments for Transition Services shall be made over the Term as part of regular payroll, subject in all cases to applicable taxes and withholdings.
In order to earn the aggregate cash payments referred to above, you must remain continuously employed as Interim CEO through June 30, 2025; provided, however, if your position as Interim CEO terminates prior to June 30, 2025 due to (i) a termination without “Cause” (as defined in Attachment B hereto), or (ii) a resignation by you for “Good Reason” (as defined in Attachment B hereto), then, so long as you sign a release of claims in a form acceptable to the Company, (A) you will be paid, in a single lump sum, an amount equivalent to your base salary for the period from the date of such termination through June 30, 2025, less all applicable taxes and withholdings, and (B) an amount equivalent to the then-unpaid aggregate cash payments (i.e., the target amount less all amounts previously paid in respect thereof), less all applicable taxes and withholdings, with such payments under (A) and (B) to be made within seventy-five (75) days after such termination.
Benefits. To the extent you are not already eligible in connection with your service as Executive Chairman, you will be eligible for the Company’s standard benefits available to similarly situated employees of the Company, including healthcare benefits and participation in the Company’s 401(k) Plan, subject to the terms and condition of all such benefits plans. You will continue to be eligible for four (4) weeks or twenty (20) days of time off per year. The Company may amend, modify or terminate its benefit plans and policies at any time or from time to time.
Proprietary Information and Inventions Agreement. The Company’s standard proprietary information, inventions, and non-solicitation agreement which you signed in connection with your engagement as Executive Chairman, a copy of which is provided herewith as Attachment C, shall remain in full force and effect.
At-Will Employment. As an at-will employer, the Company cannot guarantee your employment for any specific duration. You are free to quit and the Company is entitled to terminate your employment at any time, with or without cause or prior warning.
IRC Section 409A. The intent of the parties is that payments and benefits under this CEO Letter Agreement comply with, or be exempt from, Section 409A of the Internal Revenue Code of 1986, as amended (“Section 409A”), to the extent subject thereto, and accordingly, to the maximum extent permitted, this CEO Letter Agreement shall be interpreted and administered to be in compliance therewith. Notwithstanding anything contained herein to the contrary, you will not be considered to have terminated employment with the Company for purposes of any payments under this CEO Letter Agreement which are subject to Section 409A of the Code until you would be considered to have incurred a “separation from service” from the Company within the

meaning of Section 409A of the Code. Each amount to be paid or benefit to be provided under this CEO Letter Agreement shall be construed as a separate identified payment for purposes of Section 409A of the Code. Without limiting the foregoing and notwithstanding anything contained herein to the contrary, to the extent required in order to avoid accelerated taxation and/or tax penalties under Section 409A of the Code, amounts that would otherwise be payable and benefits that would otherwise be provided pursuant to this CEO Letter Agreement or any other arrangement between you and the Company during the six-month period immediately following your separation from service shall instead be paid on the first business day after the date that is six months following your separation from service (or, if earlier, your date of death). To the extent required to avoid an accelerated or additional tax under Section 409A of the Code, amounts reimbursable to you under this CEO Letter Agreement shall be paid to you on or before the last day of the year following the year in which the expense was incurred and the amount of expenses eligible for reimbursement (and in kind benefits provided to you) during one year may not affect amounts reimbursable or provided in any subsequent year. The Company makes no representation that any or all of the payments described in this CEO Letter Agreement will be exempt from or comply with Section 409A of the Code and makes no undertaking to preclude Section 409A of the Code from applying to any such payment.
Governing Law and Choice of Forum. Your employment will be governed by and interpreted under the laws of the State of Colorado without regard to its conflict of law principles. The parties hereby agree that all demands, claims, actions, causes of action, suits, proceedings and litigation between or among the parties or arising out of the employment relationship shall be filed, tried and litigated exclusively in a state or federal court located in Colorado. In connection with the foregoing, the parties hereto irrevocably consent to the jurisdiction and venue of such courts and expressly waive any claims or defenses for lack of jurisdiction, non-convenience, or proper venue by such courts.
Successors and Assigns. You may not assign or transfer your rights or delegate your duties, responsibilities, or obligations under this CEO Letter Agreement to any person, firm, or corporation without the prior written consent of the Company. This CEO Letter Agreement and all of the Company’s rights and obligations hereunder may be assigned, delegated, or transferred by the Company to any affiliate or subsidiary of the Company, or to any business entity which at any time by merger, consolidation or otherwise acquires all or substantially all of the assets of the Company or to which the Company transfers all or substantially all of its assets. This CEO Letter Agreement shall inure to the benefit of and shall be binding upon the parties hereto, and any successors to or assigns of the Company.
Counterparts. This CEO Letter Agreement may be executed in any number of counterparts, each of which when so executed and delivered shall be deemed an original, and all of which together shall constitute one and the same.
Entire Agreement. By signing this CEO Letter Agreement, you agree that the terms in this CEO Letter Agreement, the Executive Chairman Agreement (as modified by this CEO Agreement), and the terms set forth in the standard proprietary information, inventions and non-solicitation

agreement) constitute the entire agreement between the parties and supersede all other agreements or understandings with respect to the subject matter hereof.
