Odyssey Marine Exploration, Inc. (“Odyssey”) is holding its Annual Meeting of Stockholders (the “Annual Meeting”) on June 4, 2014, beginning at 9:30 a.m. (Eastern time). Attached as Exhibit 99.1 to this Current Report on Form 8-K is an excerpt from the script of the presentation to be made by Gregory P. Stemm, Odyssey’s Chief Executive Officer, at the Annual Meeting.

The information in this Item 7.01, including Exhibit 99.1, will not be treated as filed for the purposes of Section 18 of the Securities Exchange Act of 1934 or otherwise subject to the liabilities of that section. This information will not be incorporated by reference into a filing under the Securities Act of 1933, or into another filing under the Securities Exchange Act of 1934, unless that filing expressly refers to specific information in this report. The furnishing of the information in this Item 7.01 of this report is not intended to and does not, constitute a representation that such furnishing is required by Regulation FD or that the information in this Item 7.01 is material investor information that is not otherwise publicly available.

Forward Looking Information

Odyssey believes the information set forth in this Item 7.01, including Exhibit 99.1, may include “forward looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933 and Section 21E of the Securities Act of 1934. Certain factors that could cause results to differ materially from those projected in the forward-looking statements are set forth in “Risk Factors” in Part I, Item 1A of the Company’s Annual Report on Form 10-K for the year ended December 31, 2013, which was filed with the Securities and Exchange Commission (the “SEC”) on March 17, 2014. The financial and operating projections as well as estimates of mining assets are based solely on the assumptions developed by Odyssey that it believes are reasonable based upon information available to Odyssey as of the date of this report. All projections and estimates are subject to material uncertainties, and should not be viewed as a prediction or an assurance of actual future performance. The validity and accuracy of Odyssey’s projections will depend upon unpredictable future events, many of which are beyond Odyssey’s control and, accordingly, no assurance can be given that Odyssey’s assumptions will prove true or that its projected results will be achieved.
