Amendment Description | EXPLANATORY NOTE Odyssey Marine Exploration, Inc. (the “Company,” “we,” or “our”) is filing this Form 10-K/A (this “Amendment”) to further amend our Annual Report on Form 10-K for the year ended December 31, 2021, which we filed with the Securities and Exchange Commission (the “SEC”) on March 31, 2022 (the “Original Filing”), as amended by the Form 10-K/A that we filed with the SEC on July 19, 2022 (the "First Amendment"). As used in this Amendment, the Original Filing, as previously amended by the First Amendment, is referred to as the "Amended Filing." This Amendment is being filed to amend and restate Item 2 of Part I and Item 9A of Part I in their entirety in response to comments received from the SEC staff with respect to the First Amendment. This Amendment also restates Item 15 of Part IV in its entirety and, pursuant to Rule 12b-15, new certifications by our principal executive officer and our chief financial officer as required by Section 302 and Section 906 of the Sarbanes-Oxley Act of 2002 are filed as exhibits to this Amendment. Other than the items referenced above, this Amendment does not attempt to modify or update the Amended Filing. This Amendment does not reflect events occurring after the date of the Original Filing or modify or update those disclosures that may be affected by subsequent events. Such subsequent matters are or will be addressed in subsequent reports filed by the Company with the SEC. Accordingly, this Amendment should be read in conjunction with the Amended Filing. Capitalized terms not defined in this Amendment have the meaning given to them in the Original Filing. |
