Item 9A. Controls and Procedures Evaluation of disclosure controls and procedures . The Company’s disclosure controls and procedures are designed to ensure that information required to be disclosed by the Company in reports filed or submitted under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. The Company’s disclosure controls and procedures are also designed to ensure such information is accumulated and communicated to management, including the principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosures. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance that control objectives are attained. Based upon this evaluation, our Chief Executive Officer and Interim Chief Financial Officer have concluded that our disclosure controls and processes were not effective at December 31, 2025, because of the material weakness in our internal control over financial reporting described below. Management’s Annual Report on Internal Control over Financial Reporting The Company’s management, including the Chief Executive Officer and the Interim Chief Financial Officer, are responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule 13a-15(f) of the Exchange Act. The Company's management conducted an assessment of the Company's internal control over financial reporting based on the framework and criteria established by the Committee of Sponsoring Organizations of the Treadway Commission in "Internal Control - Integrated Framework" (2013). As of December 31, 2025, Company’s management has evaluated the effectiveness of its internal control over financial reporting under the Exchange Act and concluded, that our internal control over financial reporting was not effective based on those criteria because of the material weakness described below. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company’s annual or interim financial statements will not be prevented or detected on a timely basis. The Company previously identified deficiencies in its internal control over financial reporting that represented a material weakness. Specifically, the Company’s management determined that the Company did not, as of December 31, 2024, design and maintain effective internal controls over financial reporting related to ineffective design and operation of controls over significant complex transactions, which resulted in restatements of all interim periods of 2024. As of December 31, 2025, the material weakness had not yet been remediated. The Company believes that, notwithstanding the material weakness mentioned above, the consolidated financial statements contained in this Form 10-K present fairly, in all material respects, the consolidated financial positions, results of operations and cash flows of the Company in conformity with generally accepted accounting principles as of the dates and for the periods stated therein. Remediation Plan. The Company continues to implement certain remediation actions and continues to test and evaluate the elements of the remediation plan. These elements include: • Design and implementation of a Significant Complex Transaction policy which identifies transactions that should be evaluated for additional 3 rd party expert evaluation for proper accounting treatment; The Company believes that the actions listed above will provide appropriate remediation of the material weakness; however, the testing of the effectiveness of the controls has not been completed by the Company. Due to the nature of the remediation process and the need for sufficient time after implementation to evaluate and test the effectiveness of the controls, no assurance can be given as to the timing for completion of remediation. The material weaknesses will be fully 56 Table of Contents remediated when the Company concludes that the controls have been operating for sufficient time and independently validated by management. Remediation of previously reported Material Weaknesses The Company previously identified deficiencies in its internal control over financial reporting that represented material weaknesses. Specifically, the Company’s management determined that the Company did not, as of December 31, 2024, design and maintain effective internal controls over financial reporting related to failure to remediate reported material weaknesses over years 2021-2023 related to ineffective design and operation of user access controls. These historical deficiencies stemmed from a lack of qualified accounting and financial reporting personnel and inadequate procedures for the accounting close process. Remediation efforts in 2022, 2023 and 2024 were unsuccessful as a result of the significant turnover of key finance personnel. Specifically, despite significant process improvements and hiring of personnel, at the end of 2023 there was a gap in the implementation of the remediation initiatives with certain tasks that would have to be completed to remediate the material weakness not being handed over to the new personnel. During the year ended December 31, 2025, the Company implemented and tested remediation actions including these specific elements: • Designed and implemented user access controls and proper segregation of duties for all critical accounting systems, supported by formal policies and training for all Information Technology personnel. The Company concludes that the controls have been operating for sufficient time and independently validated by management and the material weakness related to the design and operation of user access controls is fully remediated. Changes in internal control over financial reporting. During the fiscal year ended December 31, 2025, there were no other changes in our internal control over financial reporting identified in connection with the evaluation required by Rules 13a-15(d) and 15d-15(d) of the Exchange Act that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Inherent limitation on the effectiveness of internal control. The effectiveness of any system of internal control over financial reporting, including ours, is subject to inherent limitations, including the exercise of judgment in designing, implementing, operating, and evaluating the controls and procedures, and the inability to eliminate misconduct completely. Accordingly, in designing and evaluating the disclosure controls and procedures, management recognizes that any system of internal control over financial reporting, including ours, no matter how well designed and operated, can only provide reasonable, not absolute assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints, and that management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs. Moreover, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. We intend to continue to monitor and upgrade our internal controls as necessary or appropriate for our business but cannot assure you that such improvements will be sufficient to provide us with effective internal control over financial reporting. Item 9B. Other Information Trading Plans During the most recent fiscal quarter ended December 31, 2025, no director or Section 16 officer of the Company adopted or terminated a “Rule 10b5-1 trading arrangement” or “non-Rule 10b5-1 trading arrangement,” as each term is defined in Item 408(a) of Regulation S-K. Item 9C. Disclosures Regarding Foreign Jurisdiction that Prevent Inspections None. 57 Table of Contents PART III Item 10. Directors, Executive Officers and Corporate Governance The information required by this Item (other than the information set forth in the following paragraphs under this Item 10) will be included in our Definitive Proxy Statement to be filed with the SEC within 120 days after the end of the fiscal year pursuant to Regulation 14A in connection with our 2026 Annual Meeting of Stockholders and is incorporated herein by reference. Adoption of Code of Ethics The Company has adopted a Code of Business Conduct and Ethics (the "Code") applicable to all of our board of director members, employees and executive officers, including our Chief Executive Officer (Principal Executive Officer), and Chief Financial Officer (Principal Financial Officer and Principal Accounting Officer). The Company has made the Code available on our website at http://ir.nauticusrobotics.com. The Company intends to satisfy the public disclosure requirements regarding (1) any amendments to the Code, or (2) any waivers under the Code given to our Principal Executive Officer, Principal Financial Officer and Principal Accounting Officer by posting such information on our website at http://ir.nauticusrobotics.com. There were no amendments to the Code or waivers granted thereunder relating to the Principal Executive Officer, Principal Financial Officer or Principal Accounting Officer during 2025. Adoption of Insider Trading Policy The Company has adopted an insider trading policy governing the purchase, sale, and other dispositions of its securities by our directors, officers and employees that we believe is reasonably designed to promote compliance with insider trading laws, rules and regulations and any applicable listing standards. A copy of our insider trading policy is filed as Exhibit 19 to this Annual Report. Item 11. Executive Compensation The information required by this Item (other than the information set forth in the following paragraphs under this Item 11) will be included in our Definitive Proxy Statement to be filed with the SEC within 120 days after the end of the fiscal year pursuant to Regulation 14A in connection with our 2026 Annual Meeting of Stockholders and is incorporated herein by reference. Recovery Analysis of Incentive-based Compensation We previously restated our unaudited condensed consolidated financial statements as of and for the quarterly periods ended March 31, June 30 and September 30, 2024 (the “2024 Restated Periods”). In consultation with the Audit Committee of our Board of Directors (the “Audit Committee”) and our auditors, we made the determination to restate such financial statements following the identification of errors related to the accounting treatment of significant unusual transactions (collectively, the “2024 Restatement”). Due to such errors, the Company’s management and the Audit Committee concluded that our previously issued financial statements for the 2024 Restated Periods should no longer be relied upon. The 2024 Restatement does not affect any of the Company’s key business metrics or compliance with any financial covenants. The 2024 Restatement does not have any impact on management's or other employees' compensation, as incentive compensation plans were based on the attainment of metrics and operational goals unaffected by the adjustments. Accordingly, the Company concluded that recovery of erroneously awarded compensation was not required pursuant to the Clawback Policy. Item 12. Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters The information required by this Item is incorporated herein by reference to information contained in our Definitive Proxy Statement to be filed with the SEC within 120 days after the end of the fiscal year pursuant to Regulation 14A in connection with our 2026 Annual Meeting of Stockholders.
