Capitol Federal Financial, Inc.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, evaluated the Company's disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, the "Act") as of March 31, 2026. Based upon this evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that, as of March 31, 2026, such disclosure controls and procedures were effective to ensure that information required to be disclosed by the Company in the reports it files or submits under the Act is accumulated and communicated to the Company's management (including the Chief Executive Officer and Chief Financial Officer) to allow timely decisions regarding required disclosure, and 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
