TIMBERLAND 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) of the Securities Exchange Act of 1934 (the “Exchange Act”)) was carried out under the supervision and with the participation of the Company’s Chief Executive Officer (principal executive officer), Chief Financial Officer (principal financial officer) and several other members of the Company’s senior management as of the end of the period covered by this report. The Company’s Chief Executive Officer and Chief Financial Officer concluded that as of March 31, 2025, the Company’s disclosure controls and procedures were effective in ensuring that the information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is (i) accumulated and communicated to the Company’s management (including the Chief Executive Officer and Chief Financial Officer) in a timely manner to allow timely decisions regarding required disclosure, and (ii) recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

(b)Changes in Internal Controls: There have been no changes in our internal control over financial reporting during the quarter ended March 31, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

The Company does not expect that its disclosure controls and procedures and internal control over financial reporting will prevent all errors and 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 in controls or procedures can occur because of simple error or mistake. 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 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 over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or 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.
