Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures and Changes in Internal Control over Financial Reporting

Bancshares maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed in Bancshares’ Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’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) or 15d-15(e) promulgated under the Exchange Act) as of December 31, 2023, 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 December 31, 2023, that Bancshares’ disclosure controls and procedures are effective at the reasonable assurance level to ensure that the information required to be disclosed in Bancshares’ periodic filings with the Securities and Exchange Commission is recorded, processed, summarized and reported within the time periods specified.

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 December 31, 2023 that have materially affected, or are reasonably likely to materially affect, Bancshares’ internal control over financial reporting.
