**PART III - NARRATIVE**

State below in reasonable details 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. (Attach extra Sheets if Needed).

Nauticus Robotics, Inc. (the "Company") is filing this Form 12b-25 because it has determined that it is unable to file its Annual Report on Form 10-K for the fiscal year ended December 31, 2025 (the "Form 10-K") within the prescribed time period without unreasonable effort or expense. The delay is due to Company's ongoing review of its Series A Convertible Preferred Stock, Series B Convertible Preferred Stock and Series C Convertible Preferred Stock as equity, rather than debt, on the balance sheet of the Company. The Company is working diligently to complete the review, but due to the extended coordination, evaluation and communication needed to conduct the analysis, the Company expects to file the Form 10-K by April 15, 2026.

***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, Section 21E of the Securities Exchange Act of 1934, as amended, and the Private Securities Litigation Reform Act of 1995, as amended, and are intended to enjoy the protection of the safe harbor for forward-looking statements provided by federal securities laws. These forward-looking statements include statements regarding the accounting treatment of the Company's preferred stock and the timing of the filing of the Form 10-K and other public disclosures and related matters. These statements may be preceded by, followed by, or include the words "believes," "estimates," "expects," "projects," "forecasts," "may," "will," "should," "seeks," "plans," "scheduled," "anticipates," "intends," or "continue" or similar expressions. Forward-looking statements inherently involve risks and uncertainties that may cause actual events, results, or performance to differ materially from those indicated by such statements. These forward-looking statements are based on management's current expectations and beliefs, as well as a number of assumptions concerning future events. There can be no assurance that the events, results, or trends identified in these forward-looking statements will occur or be achieved. Forward-looking statements speak only as of the date they are made, and the Company is not under any obligation and expressly disclaims any obligation, to update, alter, or otherwise revise any forward-looking statement, whether as a result of new information, future events, or otherwise, except as required by law. Readers should carefully review the statements set forth in the reports which the Company has filed or will file from time to time with the SEC for a more complete discussion of the risks and uncertainties facing the Company and that could cause actual outcomes to be materially different from those indicated in the forward-looking statements made by the Company, in particular the sections entitled "Risk Factors" and "Cautionary Note Regarding Forward-Looking Statements" in documents filed from time to time with the SEC, including the Company's most recent Annual Report on Form 10-K and subsequently filed Quarterly Reports on Form 10-Q. Should one or more of these risks, uncertainties, or other factors materialize, or should assumptions underlying the forward-looking information or statements prove incorrect, actual results may vary materially from those described herein as intended, planned, anticipated, believed, estimated, or expected.
