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

On November 6, 2025, the Board of Directors (the “Board”) of Alamo Group Inc. (the “Company”) adopted the Alamo Group Inc. Nonqualified Deferred Compensation Plan, effective January 1, 2026 (the “Deferred Compensation Plan”), pursuant to which eligible employees may receive discretionary contributions of up to 6% of their base salary and bonus (the “Discretionary Contributions”). Eligible employees are selected for participation by the Compensation Committee of the Board of Directors of the Company and include Robert P. Hureau, the Company’s President & CEO, Agnieszka K. Kamps, the Company’s EVP & CFO, and Kevin J. Thomas, the Company’s EVP Industrial Equipment. The Discretionary Contributions will generally vest 100% following the participant’s satisfaction of three-years of service with the Company and its affiliates, subject to earlier acceleration in the event of a change in control of the Company, and will be paid upon the earliest to occur of the participant’s (i) separation from service, (ii) death and (iii) disability. In recognition of the termination of the Alamo Group Inc. Supplemental Executive Retirement Plan (the “SERP”) with respect to new participants, the Company will credit the Deferred Compensation Plan accounts of Ms. Kamps and Mr. Thomas with an initial contribution equal to the actuarial present value of their SERP account, calculated as of December 31, 2025, and which they otherwise would have forfeited due to not satisfying the ten-year service requirement set forth in the SERP.

The foregoing summary description of the Deferred Compensation Plan does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Deferred Compensation Plan, which is filed as Exhibit 10.1 hereto and incorporated by reference herein.
