FS Bancorp, Inc.

(i) Evaluation of Disclosure Controls and Procedures.

An evaluation of the disclosure controls and procedures as defined in Rule 13a-15(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) was carried out as of December 31, 2024 under the supervision and with the participation of the Company’s Chief Executive Officer (“CEO”), Chief Financial Officer (“CFO”), and several other members of the Company’s senior management. In designing and evaluating the Company’s disclosure controls and procedures, management recognized that disclosure controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the disclosure controls and procedures are met. Additionally, in designing disclosure controls and procedures, management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible disclosure controls and procedures. The design of any disclosure controls and procedures also is 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.

The Company’s CEO (principal executive officer) and CFO (principal financial officer) concluded that based on their evaluation at December 31, 2024, the Company’s disclosure controls and procedures were effective in ensuring that information we are required to disclose in the reports we file or submit under the Exchange Act is (1) recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and (2) accumulated and communicated to FS Bancorp management, including its CEO and CFO, as appropriate to allow timely decisions regarding required disclosure, specified in the SEC’s rules and forms.

a) Management’s Report on internal control over financial reporting.

FS Bancorp’s management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule 13a‑15(f) of the Exchange Act. FS Bancorp’s internal control system is designed to provide reasonable assurance to our management and the Board of Directors regarding the preparation and fair presentation of published financial statements for external purposes in accordance with generally accepted accounting principles.

This process includes policies and procedures that: (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions of FS Bancorp; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of FS Bancorp are being made only in accordance with authorizations of management and directors of FS Bancorp; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of FS Bancorp’s assets that could have a material effect on the financial statements. A control procedure, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Also, 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. Additionally, in designing disclosure controls and procedures, FS Bancorp’s management was required to apply its judgment in evaluating the cost-benefit relationship of possible disclosure controls and procedures. The design of any disclosure controls and procedures 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. As a result of these inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Furthermore, projections of any evaluation of effectiveness to future periods are subject to risk that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate.

FS Bancorp’s management assessed the effectiveness of FS Bancorp’s internal control over financial reporting as of December 31, 2024. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control-Integrated Framework (2013 Framework). Based on management’s assessment, it was concluded that, as of December 31, 2024, FS Bancorp’s internal control over financial reporting was effective based on those criteria.

c) Changes in internal control over financial reporting.

There were no changes in FS Bancorp’s internal control over financial reporting during FS Bancorp’s most recent fiscal quarter that would have materially affected or is reasonably likely to materially affect, FS Bancorp’s internal control over financial reporting.
