On November 3, 2026, the Board of Directors of Weyco Group, Inc. (the “Company”) approved and adopted an amended and restated Code of Business Ethics (the “Code”), effective November 3, 2026. The Code applies to the Company’s directors, officers and employees, including the Company’s principal executive officer, principal financial officer and principal accounting officer.

The amended and restated Code reflects updates intended to enhance and clarify the Company’s existing standards regarding ethical conduct, compliance with applicable laws and Company policies, conflicts of interest, protection and appropriate use of Company and employee information, and the reporting of potential violations. The amended and restated Code also includes various other administrative, stylistic and non-substantive changes. The amendments did not result in any waiver, explicit or implicit, of any provision of the Company’s prior code of ethics.

The foregoing description of the amendments to the Code is a summary only and is qualified in its entirety by reference to the full text of the Code, which is filed herewith as Exhibit 14.1 and is incorporated herein by reference. The Code is also available on the Company’s website, https://www.weycogroup.com, by navigating to the “Investor Relations” page.
