Gouverneur Bancorp, Inc./MD/

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) as of the end of the period covered by this report. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered by this report, our disclosure controls and procedures were effective to ensure (1) that information required to be disclosed in the reports that the Company files or submits under the Securities Exchange Act of 1934, is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms; and (2) that they are alerted in a timely manner about material information relating to the Company required to be filed in its periodic Securities and Exchange Commission filings.

During the quarter ended December 31, 2025, there were no changes in the Company’s internal controls over financial reporting that have materially affected, or are reasonably likely to materially affect, the Company’s internal controls over financial reporting.
