Item 5.07 Submission of Matters to a Vote of Security Holders

On June 17, 2024, Nauticus Robotics, Inc. (the "Company") held a special meeting of stockholders (the "Meeting"). At the Meeting, the Company's stockholders (1) approved the issuance of shares upon the conversion of debt under the Company's Senior Secured Term Loan Agreement dated January, the Company's Original Issue Discount Exchanged Secured Convertible Debentures Due September 9, 2026 and certain warrants to purchase shares of the Company's common stock, (2) approved a proposal authorizing the board of directors of the Company to enact a reverse split of its shares at a ratio between one to six and one to seventy, and (3) approved a proposal to adjourn the Meeting to a later date or date to permit further solicitation and vote of proxies, if necessary or appropriate. While a majority of votes cast were in favor of a proposal to increase the authorized shares of the Company's common stock from 625,000,000 to 5,000,000,000, the proposal did not reach the required threshold of a majority of all issued and outstanding common stock, and was therefore not approved.

A total of 43,879,371 shares of common stock of the Company attended the Meeting by proxy or in person, representing 76.55% of the Company's outstanding common stock entitled to vote as of March 26, 2024, the record date. The results of the voting were as follows:

Proposal 1: approve an amendment to the Company’s Second Amended and Restated Certificate of Incorporation, as amended, to increase the number of authorized but unissued shares of the Company’s common stock from 625,000,000 to 5,000,000,000 shares
