SECOND AMENDMENT AGREEMENT This SECOND AMENDMENT AGREEMENT (this “Amendment”) is made as of the 10th day of June, 2025 among: (a) DMC GLOBAL INC., a Delaware corporation (“DMC Global”); (b) each Domestic Subsidiary Borrower, as defined in the Credit Agreement, as hereinafter defined (each such Domestic Subsidiary Borrower, together with DMC Global, collectively, the “Borrowers” and, individually, each a “Borrower”); (c) the Lenders, as defined in the Credit Agreement, party hereto; and (d) KEYBANK NATIONAL ASSOCIATION, a national banking association, as administrative agent for the Lenders under the Credit Agreement (the “Administrative Agent”). WHEREAS, the Borrowers, the Administrative Agent and the Lenders are parties to that certain Amended and Restated Credit and Security Agreement, dated as of December 23, 2021 (as amended and as the same may from time to time be further amended, restated or otherwise modified, the “Credit Agreement”); WHEREAS, the Borrowers, the Administrative Agent and the Lenders desire to amend the Credit Agreement to modify certain provisions thereof and add certain provisions thereto; WHEREAS, each capitalized term used herein and defined in the Credit Agreement, but not otherwise defined herein, shall have the meaning given such term in the Credit Agreement; and WHEREAS, unless otherwise specifically provided herein, the provisions of the Credit Agreement revised herein are amended effective as of the date of this Amendment; NOW, THEREFORE, in consideration of the premises and of the mutual covenants herein and for other valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Borrowers, the Administrative Agent and the Lenders agree as follows: 1. Amendment to Definitions. Section 1.1 of the Credit Agreement is hereby amended to delete the definitions of “Applicable Commitment Fee Rate”, “Applicable Margin”, “Consolidated EBITDA”, and “Debt Service Coverage Ratio” therefrom and to insert in place thereof, respectively, the following: “Applicable Commitment Fee Rate” means: (a) for the period from the Second Amendment Effective Date through August 31, 2025, thirty-five (35.00) basis points; and (b) commencing with the Consolidated financial statements of DMC Global for the fiscal quarter ending June 30, 2025, the number of basis points set forth in the

2 following matrix, based upon the result of the computation of the Leverage Ratio as set forth in the Compliance Certificate for such fiscal period and, thereafter, as set forth in each successive Compliance Certificate, as provided below: Leverage Ratio Applicable Commitment Fee Rate Greater than or equal to 3.00 to 1.00 45.00 basis points Greater than or equal to 2.00 to 1.00 but less than 3.00 to 1.00 40.00 basis points Greater than or equal to 1.00 to 1.00 but less than 2.00 to 1.00 35.00 basis points Less than 1.00 to 1.00 30.00 basis points Notwithstanding the language in subsection (b) of the definition of Applicable Commitment Fee Rate, the first date on which the Applicable Commitment Fee Rate is subject to change is September 1, 2025. After September 1, 2025, changes to the Applicable Commitment Fee Rate shall be effective on the first day of the calendar month following each date upon which the Administrative Agent should have received, pursuant to Section 5.3(c) hereof, the Compliance Certificate. The above pricing matrix does not modify or waive, in any respect, the requirements of Section 5.7 hereof, the rights of the Administrative Agent and the Lenders to charge the Default Rate, or the rights and remedies of the Administrative Agent and the Lenders pursuant to Articles VIII and IX hereof. Notwithstanding anything herein to the contrary, (i) during any period when the Borrowers shall have failed to timely deliver the Consolidated financial statements pursuant to Section 5.3(a) or (b) hereof, or the Compliance Certificate pursuant to Section 5.3(c) hereof, until such time as the appropriate Consolidated financial statements and Compliance Certificate are delivered, the Applicable Commitment Fee Rate shall, at the election of the Administrative Agent (which may be retroactively effective), be the highest rate per annum indicated in the above pricing grid regardless of the Leverage Ratio at such time, and (ii) in the event that any financial information or certification provided to the Administrative Agent in the Compliance Certificate is shown to be inaccurate (regardless of whether this Agreement or the Commitment is in effect when such inaccuracy is discovered), and such inaccuracy, if corrected, would have led to the application of a higher Applicable Commitment Fee Rate for any period (an “Applicable Commitment Fee Period”) than the Applicable Commitment Fee Rate applied for such Applicable Commitment Fee Period, then (A) the Borrowers shall promptly deliver to the Administrative Agent a corrected Compliance Certificate for such Applicable Commitment Fee Period, (B) the Applicable Commitment Fee Rate shall be determined based on such corrected Compliance Certificate, and (C) the Borrowers shall promptly pay to the Administrative Agent, for the benefit of the Lenders, the accrued additional fees owing as a result of such increased Applicable Commitment Fee Rate for such Applicable Commitment Fee Period. “Applicable Margin” means:

3 (a) for the period from the Second Amendment Effective Date through August 31, 2025, two hundred fifty (250.00) basis points for SOFR Loans and one hundred fifty (150.00) basis points for Base Rate Loans; and (b) commencing with the Consolidated financial statements of DMC Global for the fiscal quarter ending June 30, 2025, the number of basis points (depending upon whether Loans are SOFR Rate Loans or Base Rate Loans) set forth in the following matrix, based upon the result of the computation of the Leverage Ratio as set forth in the Compliance Certificate for such fiscal period and, thereafter, as set forth in each successive Compliance Certificate, as provided below: Leverage Ratio Applicable Basis Points for SOFR Loans Applicable Basis Points for Base Rate Loans Greater than or equal to 3.00 to 1.00 350.00 250.00 Greater than or equal to 2.50 to 1.00 but less than 3.00 to 1.00 325.00 225.00 Greater than or equal to 2.00 to 1.00 but less than 2.50 to 1.00 300.00 200.00 Greater than or equal to 1.50 to 1.00 but less than 2.00 to 1.00 275.00 175.00 Greater than or equal to 1.00 to 1.00 but less than 1.50 to 1.00 250.00 150.00 Less than 1.00 to 1.00 225.00 125.00 Notwithstanding the language in subsection (b) of the definition of Applicable Margin, the first date on which the Applicable Margin is subject to change is September 1, 2025. After September 1, 2025, changes to the Applicable Margin shall be effective on the first day of the calendar month following each date upon which the Administrative Agent should have received, pursuant to Section 5.3(c) hereof, the Compliance Certificate. The above pricing matrix does not modify or waive, in any respect, the requirements of Section 5.7 hereof, the rights of the Administrative Agent and the Lenders to charge the Default Rate, or the rights and remedies of the Administrative Agent and the Lenders pursuant to Articles VIII and IX hereof. Notwithstanding anything herein to the contrary, (i) during any period when the Borrowers shall have failed to timely deliver the Consolidated financial statements pursuant to Section 5.3(a) or (b) hereof, or the Compliance Certificate pursuant to Section 5.3(c) hereof, until such time as the appropriate Consolidated financial statements and Compliance Certificate are delivered, the Applicable Margin shall, at the election of the Administrative Agent (which may be retroactively effective), be the highest rate per annum indicated in the above pricing grid for Loans of that type, regardless of the Leverage Ratio at such time, and (ii) in the event that any financial information or certification provided to the Administrative Agent in the Compliance Certificate is shown to be inaccurate (regardless of whether this Agreement or the Commitment is in effect when such inaccuracy is discovered), and such inaccuracy, if corrected, would have led to the application of a higher Applicable Margin

4 for any period (an “Applicable Margin Period”) than the Applicable Margin applied for such Applicable Margin Period, then (A) the Borrowers shall promptly deliver to the Administrative Agent a corrected Compliance Certificate for such Applicable Margin Period, (B) the Applicable Margin shall be determined based on such corrected Compliance Certificate, and (C) the Borrowers shall promptly pay to the Administrative Agent, for the benefit of the Lenders, the accrued additional interest owing as a result of such increased Applicable Margin for such Applicable Margin Period. “Consolidated EBITDA” means, for any period, as determined on a Consolidated basis, (a) Consolidated Net Earnings for such period plus, without duplication, the aggregate amounts deducted in determining such Consolidated Net Earnings in respect of (i) Consolidated Interest Expense, (ii) Consolidated Income Tax Expense, (iii) Consolidated Depreciation and Amortization Charges, (iv) non-cash charges excluding inventory reserves, (v) non-recurring cash charges not incurred in the ordinary course of business as agreed to by the Administrative Agent in its discretion, (vi) unrealized foreign currency losses, (vii) non-cash stock-based compensation expense, (viii) one time integration expenses incurred in the first twelve months following consummation of an Acquisition permitted hereunder, and (ix) any transaction-related expenses related to (A) an Acquisition permitted hereunder, (B) a disposition of assets permitted hereunder or (C) the consummation of amendments to Loan Documents or other additional Loan Documents entered into on or after the First Amendment Effective Date; provided that, the sum of the amounts added back pursuant to clauses (viii) and (ix) hereof shall not exceed ten percent (10%) of Consolidated EBITDA as calculated pursuant to this definition without reference to clause (viii) or (ix), unless otherwise agreed to by the Administrative Agent in its sole discretion; minus (b) to the extent included in Consolidated Net Earnings for such period, (i) non-cash gains, (ii) non- recurring cash gains not incurred in the ordinary course of business, and (iii) unrealized foreign currency gains. Notwithstanding the foregoing, in connection with an Acquisition or material disposition of assets permitted hereunder, Consolidated EBITDA (and any other applicable financial definitions) shall be calculated for the relevant periods to include the appropriate financial items of the entity or entities that are the target of such Acquisition, or exclude the appropriate financial items attributable to the assets being disposed, to the extent (A) such items are not otherwise included (or excluded) in the financial statements for DMC Global and its Subsidiaries and (B) such items are supported by financial statements or other information reasonably satisfactory to the Administrative Agent, and to include (or exclude) appropriate pro forma adjustments reasonably acceptable to the Administrative Agent and calculated on the same basis as set forth in this definition. “Debt Service Coverage Ratio” means, as determined for the most recently completed four fiscal quarters of DMC Global on a Consolidated basis, the ratio of (a) the sum of (i) Consolidated EBITDA, minus (ii) Capital Distributions paid in cash (other than (A) those made pursuant to Section 5.15(c) hereof, and (B) those made with respect to the Arcadia Equity Repurchase, in each case of subparts (A) and (B), so long as such cash payments are made with balance sheet cash, Revolving Loans or DDTL Loans),

5 minus (iii) Consolidated Unfunded Capital Expenditures, minus (iv) Consolidated Income Tax Expense paid in cash (net of income taxes (1) refunded in cash during such period, and (2) paid in cash in Germany for income taxes incurred during the fiscal year ended December 31, 2022, in an aggregate amount not to exceed Four Million Dollars ($4,000,000) and (y) for income taxes incurred during the fiscal year ended December 31, 2023, in an aggregate amount not to exceed Seven Million Dollars ($7,000,000)), minus (v) cash Restricted Payments pursuant to Section 5.15(d) hereof (except with respect to the portion of such Restricted Payments made with balance sheet cash, Revolving Loans or DDTL Loans); to (b) Consolidated Debt Service. 2. Additions to Definitions. Section 1.1 of the Credit Agreement is hereby amended to add the following new definitions thereto in the appropriate alphabetical order: “Covenant Relief Period” means the period commencing on the first day of the fiscal quarter during which the final payment for the Arcadia Equity Repurchase is made, through the last day of the third full fiscal quarter following such final payment. “Restricted Account” means a commercial Deposit Account designated as the “restricted account” and maintained by a Borrower with the Administrative Agent as set forth in Section 5.18 hereof, subject to a Control Agreement that grants exclusive control (except to the extent such funds are used as permitted by Section 5.18 hereof) of the Deposit Account to the Administrative Agent. “Second Amendment Effective Date” means June 10, 2025. 3.

The Borrowers’ use of the proceeds of the Loans shall be for working capital and other general corporate purposes of the Companies and for the refinancing of existing Indebtedness and for Acquisitions permitted hereunder including the Arcadia Acquisition; provided that (a) the proceeds of the DDTL Loans shall be used solely for the Arcadia Equity Repurchase and (b) the proceeds of the Revolving Loans may be used for the Arcadia Equity Repurchase, so long as, (i) in the case of subpart (a) above, such funds are deposited into a Restricted Account until used

6 as designated, and (ii) in the case of subpart (b) above, such funds are used as designated within five (5) Business Days of the making of any such Loan; provided further that, notwithstanding the foregoing, proceeds of the DDTL Loans in the Restricted Account may be used to repay DDTL Loans.
