Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	NOTE 1 - BASIS OF PRESENTATION The accompanying unaudited condensed consolidated financial statements of Odyssey Marine Exploration, Inc. and subsidiaries (the “Company,” “Odyssey,” “us,” “we” or “our”) have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission and the instructions to Form 10-Q and, therefore, do not include all information and footnotes normally included in financial statements prepared in accordance with generally accepted accounting principles. These interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023. In the opinion of management, these financial statements reflect all adjustments, including normal recurring adjustments, necessary for a fair presentation of the financial position as of March 31, 2024 and the results of operations and cash flows for the interim periods presented. Operating results for the three months ended March 31, 2024, are not necessarily indicative of the results that may be expected for the full year. Going Concern Consideration We have experienced several years of net losses and may continue to do so. Our ability to generate net income or positive cash flows for the following twelve months is dependent upon financings, our success in developing and monetizing our interests in mineral exploration entities, generating income from contracted services, collecting on amounts owed to us. Our 2024 business plan requires us to generate new cash inflows to effectively allow us to perform our planned projects. We continually plan to generate new cash inflows through the monetization of our receivables and equity stakes in seabed mineral companies, financings, syndications or other partnership opportunities. If cash inflow becomes insufficient to meet our desired projected business plan requirements, we would be required to follow a contingency business plan based on curtailed expenses and fewer cash requirements. On December 1, 2023, we entered into the December 2023 Note Purchase Agreement with institutional investors pursuant to which we issued and sold to the investors the December 2023 Notes in the principal amount of up to $6.0 million and the December 2023 Warrants to purchase shares of our common stock. We issued December 2023 Notes in the aggregate amount of $3.75 million and related warrants on December 1, 2023, and December 2023 Notes in the aggregate amount of $2.25 million and related warrants on December 28, 2023. On May 3, 2024, we received a payment of approximately $9.4 million arising from a residual economic interest in a salvaged shipwreck. The balance of the proceeds from the December 2023 Notes and a portion of the proceeds received in May 2024 , together with other anticipated cash inflows, are expected to provide operating funds through at least the third quarter of 2024 . Our consolidated non-restricted cash balance at March 31, 2024 was $2.1 million. We have a working capital deficit at March 31, 2024 of $30.1 million. The total consolidated book value of our assets was approximately $20.6 million at March 31, 2024, which includes cash of $2.1 million. The fair market value of these assets may differ from their net carrying book value. The factors noted above raise substantial doubt about our ability to continue as a going concern. These condensed consolidated financial statements do not include any adjustments to the amounts and classification of assets and liabilities that may be necessary should we be unable to continue as a going concern.
