Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

Bancshares maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed in Bancshares’ reports under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to Bancshares’ management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives.

Bancshares’ management carried out an evaluation, under the supervision and with the participation of its Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of Bancshares’ disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) promulgated under the Exchange Act) as of September 30, 2024, pursuant to the evaluation of these controls and procedures required by Rule 13a-15 of the Exchange Act. Based on that evaluation, Bancshares’ management concluded, as of September 30, 2024, that Bancshares’ disclosure controls and procedures were effective at the reasonable assurance level to ensure that the information required to be disclosed in Bancshares’ periodic filings with the SEC is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

Changes in Internal Control Over Financial Reporting

There were no changes in Bancshares’ internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) during the quarter ended September 30, 2024 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
