Explanatory Note

This Form 8-A/A is being filed by DMC Global Inc., a Delaware corporation (the “Company”) to amend the disclosure in the Company’s Registration Statement on Form 8-A filed with the U.S. Securities and Exchange Commission (the “SEC”) on June 6, 2024.

On June 5, 2024, the Board of Directors of the Company declared a dividend of one right (a “Right”) in respect of each share of the Company’s common stock, $0.05 par value per share (“Common Stock”), held of record as of the close of business on June 17, 2024 (the “Record Time”) payable in respect of each such share at the Record Time. As provided in the Amended Rights Agreement (as defined below), one Right will be issued in respect of each share of Common Stock issued after the Record Time and prior to the Separation Time (as defined in the Amended Rights Agreement). Each Right initially represents the right to purchase one one-thousandth of a share of Series B Participating Preferred Stock, upon terms and subject to the conditions set forth in a Stockholder Protection Rights Agreement, dated as of June 5, 2024, between the Company and Computershare Trust Company, N.A., as Rights Agent (the “Original Rights Agreement”).

On May 30, 2025, the Company entered into Amendment No. 1 to Stockholder Protection Rights Agreement (the “Amendment,” and the Original Rights Agreement, as amended by the Amendment, the “Amended Rights Agreement”), which amends the Original Rights Agreement to extend the Expiration Time (as defined in the Amended Rights Agreement) of the Rights for one year from June 4, 2025 to June 4, 2026 (unless the Rights are earlier redeemed, exchanged or terminated in accordance with the terms and conditions of the Amended Rights Agreement).

The foregoing description of the Original Rights Agreement and the Amendment is qualified in its entirety by reference to the full text of the Original Rights Agreement, which is attached hereto as Exhibit 4.1, and the Amendment, which is attached hereto as Exhibit 4.2, each of which is incorporated herein by reference. The Rights, as amended, are in all respects subject to and governed by the provisions of the Amended Rights Agreement. The description of the Rights is qualified in its entirety by reference to the full text of the Amended Rights Agreement and the description of set forth in Items 1.01 and 5.03 of the Company's Current Report on Form 8-K filed June 6, 2024, which is incorporated herein by reference.
