Item 3.03 Material Modification to Rights of Security Holders.
To the extent required by Item 3.03 of Form 8-K, the information contained in Item 5.03 of this Current Report on Form 8-K is incorporated herein by reference.
Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.
On April 17, 2026, Nauticus Robotics, Inc. (the "Company") filed a certificate of amendment to its Second Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware (the "Certificate of Amendment") to effect a 1-for-8 reverse stock split (the “Reverse Stock Split”) of the shares of the Company's common stock, par value $0.0001 per share on April 21, 2026. No fractional shares will be issued in connection with the reverse stock split, but will instead be rounded up to the nearest whole share. The Board of Directors of the Company (the “Board”) approved the Certificate of Amendment to meet the share bid price requirements of the NASDAQ Capital Market. At a special meeting held on January 28, 2026, the Company’s stockholders approved the Board to enact one or more reverse splits of its shares at a range of ratios that includes the Reverse Stock Split ratio.
The Company's common stock is expected to begin trading on a reverse stock split-adjusted basis on the Nasdaq Capital market when the market opens on April 21, 2026. The trading symbol for the Company's common stock will remain "KITT." The Company was assigned a new CUSIP number (63911H 405) in connection with the reverse split.
All options, warrants and other convertible securities of the Company outstanding immediately prior to the effectiveness of the Certificate of Amendment will be adjusted in accordance with the terms of the plans, agreements or arrangements governing such options, warrants and other convertible securities and subject to rounding to the nearest whole share.
Each stockholder’s percentage ownership interest in the Company and proportional voting power will remain virtually unchanged by the Certificate of Amendment, except for minor changes and adjustments that will result from rounding fractional shares into whole shares. The rights and privileges of the holders of shares of the Company’s common stock will be substantially unaffected.
Item 8.01 Other Events.
On April 17, 2026, the Company issued a press release announcing the Reverse Stock Split of the shares of the Company's common stock, par value $0.0001 per share, to be effective on April 21, 2026. A copy of the press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.
The Company currently has several active registration statements listed below (the “Registration Statements”) on Form S-3 and on Form S-8 on file with the SEC. SEC regulations permit the Company to incorporate by reference future filings made with the SEC pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Securities Exchange Act of 1934, as amended, prior to the termination of the offerings covered by registration statements filed on Form S-3 or Form S-8, as applicable. The information incorporated by reference is considered to be part of the prospectus and prospectus supplements included within each of those registration statements. Information in this report is therefore intended to be automatically incorporated by reference into each of the active registration statements listed below, thereby amending them. Pursuant to Rule 416(b) under the Securities Act of 1933, as amended, the number of undistributed shares of common stock deemed to be covered by each of the Registration Statements will be proportionately reduced to a number of shares of the post-reverse-split common stock, as applicable, giving effect to the Reverse Stock Split. The Registration Statements are as follows: (a) Registration Statements No. 333-284675 on Form S-3; and (b) Registration Statements Nos. 333-269349, 333-280824, 333-288641, and 333-294007 on Form S-8.
