PART III – NARRATIVE State below in reasonable detail the reasons 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. Castor Maritime Inc. (the “Company”) has determined that it is unable to file its Annual Report on Form 20-F for the fiscal year ended December 31, 2024 by the prescribed due date without unreasonable effort or expense. As disclosed the Company’s report on Form 6-K furnished to the Securities and Exchange Commission on December 17, 2024, the Company completed its acquisition of a majority stake in Münchmeyer Petersen & Co. GmbH (“MPC Capital”) on December 16, 2024. This transaction will be referred to herein as the “Acquisition”. The Company requires additional time to finalize its consolidated financial statements due to the need to consolidate MPC Capital, whose financial statements need to be converted from German GAAP to U.S. GAAP, and to complete the acquisition accounting with respect to the Acquisition. Cautionary Statement Regarding Forward-Looking Statements This Form 12b-25 contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements are based on management’s current expectations or beliefs about the Company’s future plans, expectations and objectives. Although the Company believes the expectations reflected in any forward-looking statement are based on reasonable assumptions, it can give no assurance that its expectations will be attained, and it is possible that actual results may differ materially from those indicated by these forward-looking statements due to a variety of risks and uncertainties. The information set forth herein speaks only as of the date hereof, and we disclaim any intention or obligation to update any forward looking statements as a result of developments occurring after the date of this communication, except to the extent required by applicable law.
