PART III – NARRATIVE

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-CEN, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

Landmark Bancorp, Inc. (the “Company”) is unable to file its Annual Report on Form 10-K for the year ended December 31, 2025 (the “2025 Form 10-K”) by the prescribed due date without unreasonable effort or expense for the reasons described below.

After the Company’s earnings release on January 28, 2026, information was brought to the attention of management, which promptly informed the Audit and Risk Committee (the “Committee”) of the Board of Directors of the Company, that caused management and the Committee to commence an internal investigation with the assistance of outside counsel and advisors, regarding allegations of misconduct by a non-executive officer employee of the Company’s wholly-owned subsidiary, Landmark National Bank. The investigation is ongoing and all parties are working diligently to complete the investigation. The amounts at issue are not expected to materially impact any previously reported periods, and the Company currently does not believe that any of the matters under investigation materially affect any previously issued financial statements or the information in the Company’s earnings release on January 28, 2026; however, the investigation has not been completed and actual results may differ from current expectations.

This matter affected the progress of the Company’s annual close process and preparation of the 2025 Form 10-K. Management is in the process of completing the financial statements and assessing matters relating to the Company’s internal control over financial reporting, including the effectiveness of the Company’s internal control over financial reporting.

Management is working under the Committee’s oversight to complete the additional procedures necessary to file the 2025 Form 10-K as soon as practicable.

Forward-Looking Statements

This Form 12b-25 contains “forward-looking statements” as defined in the Private Securities Litigation Reform Act of 1995 that are subject to risks and uncertainties, including statements regarding the Company’s expectations regarding the timing of filing its 2025 Form 10-K on or before the fifteenth day following its prescribed due date (the “extension deadline”), the consistency of the financial statements in the 2025 Form 10-K with the Company’s previously reported financial results and the completion of matters necessary to permit filing by the extension deadline. Such forward-looking statements are based on assumptions about many important factors that could cause actual results to differ materially from those in the forward-looking statements, including risks identified in the Company’s most recent periodic reports and other Securities and Exchange Commission filings, all of which are available on the Company’s website. The Company can provide no assurance that these forward-looking statements will be achieved, and actual results could differ materially from those suggested by such forward-looking statements. The Company does not undertake to update its forward-looking statements unless otherwise required by the federal securities laws.
