Burke & Herbert Financial Services Corp.

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of September 30, 2026. Based on their evaluation of the Company’s disclosure controls and procedures, the Company’s Chief Executive Officer and Chief Financial Officer have concluded that, as of September 30, 2026, our disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Effective on May 1, 2026, Burke & Herbert completed the LNKB Merger. During the second and third quarters of 2026, management commenced an evaluation of the design and operating effectiveness of internal controls over financial reporting related to the LNKB acquired business. The evaluation of changes to processes, technology systems, and other components of internal control over financial reporting related to the LNKB acquired business is ongoing. Except for the changes made in connection with the LNKB Merger, there were no changes in our internal control over financial reporting that occurred during the quarter ended September 30, 2026, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
