Sound Financial Bancorp Inc

(a) Evaluation of Disclosure Controls and Procedures

An evaluation of the Company’s disclosure controls and procedures (as defined in Rule 13a -15(e) under the Securities Exchange Act of 1934 (the “Act”), was carried out under the supervision and with the participation of the Company’s principal executive officer and principal financial officer, and several other members of the Company’s senior management as of December 31, 2023. Based on this evaluation, the principal executive officer and the principal financial officer concluded that the Company’s disclosure controls and procedures were effective as of December 31, 2023 in ensuring that the information required to be disclosed by the Company in the reports it files or submits under the Act is: (i) accumulated and communicated to the Company’s management (including the Chief Executive Officer and Chief Financial Officer) in a timely manner, and (ii) recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

We intend to continually review and evaluate the design and effectiveness of the Company’s disclosure controls and procedures and to improve the Company’s controls and procedures over time and to correct any deficiencies that we may discover in the future. The goal is to ensure that senior management has timely access to all material financial and non-financial information concerning the Company’s business. While we believe the present design of the disclosure controls and procedures is effective to achieve this goal, future events affecting our business may cause the Company to modify its disclosure controls and procedures.

The Company does not expect that its disclosure controls and procedures will prevent all error and all fraud. A control procedure, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control procedure are met. Because of the inherent limitations in all control procedures, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple errors or mistakes. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any control procedure is also based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies and procedures may deteriorate. Because of the inherent limitations in a cost-effective control procedure, misstatements due to error or fraud may occur and not be detected.

(b) Internal Control Over Financial Reporting

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of Sound Financial Bancorp is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). The Company's internal control over financial reporting is a process designed to provide reasonable assurance to the Company's management and board of directors regarding the reliability of financial reporting and the preparation of the financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America. There are inherent limitations in the effectiveness of any system of internal control over financial reporting, including the possibility of human error and circumvention or overriding of controls. Accordingly, even an effective system of internal control over financial reporting can provide only reasonable assurance with respect to financial statement preparation. Projections of any evaluation of effectiveness to future periods are subject to the risks that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate.

Management assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 2023. In making this assessment, it used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework (2013). Based on this assessment, we concluded that, as of December 31, 2023, the Company's internal control over financial reporting was effective based on those criteria.

(c) Changes in Internal Controls over Financial Reporting

As required by Rule 13a-15(d), our management, including our Chief Executive Officer and Chief Financial Officer, also conducted an evaluation of our internal control over financial reporting to determine whether any changes occurred during quarter ended December 31, 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. There were no changes in our internal controls over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that occurred during the quarter ended December 31, 2023, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
