Odyssey Marine Exploration, Inc. filed Amendment No. 2 to its annual report for the year ended December 31, 2025 to revise mineral property disclosures in response to an SEC comment letter. The update clarifies which offshore mineral projects are material under Subpart 1300 of Regulation S-K and adds required detail, without changing any previously reported financial results.
The company concludes its mining operations are material to its business and lists only indirect, minority interests in exploration-stage marine projects, including approximate equity stakes of 15.7% in CIC Limited and 7.0% in Ocean Minerals, LLC, both holding Cook Islands exploration licenses for polymetallic nodules and deemed material. Smaller interests in gold and phosphate projects are classified as not material. Across all properties, no mineral reserves have been disclosed, no commercial production has occurred, and mineral resources, where identified, do not have demonstrated economic viability. Formal internal controls over mineral resource and reserve estimation have not yet been established; the company relies on information from project operators but expects to implement controls as exploration advances. As of June 30, 2025, non-affiliate equity was valued at approximately $38.3 million based on a $1.18 share price, and 58,574,115 common shares were outstanding on June 15, 2026.
Odyssey Marine Exploration filed an amendment to its annual report to update how it describes its marine mineral properties after a review by the SEC. The change focuses on clarifying which projects are material and aligning the disclosure with Subpart 1300 of Regulation S-K.
The company now identifies two material exploration-stage polymetallic nodule projects in the Cook Islands EEZ: the CIC Project, where it holds an approximate 13.1% equity interest in CIC Limited, and the OML Project, with an approximate 5.3% equity interest in Ocean Minerals, LLC. Its Lihir Gold Project in the Papua New Guinea EEZ is classified as not material.
As of December 31, 2025, all listed properties were in the exploration stage, with no mineral reserves, commercial harvesting, or mineral production disclosed. Odyssey holds only indirect economic interests, and mineral resources, where referenced, are noted as not having demonstrated economic viability. The company has not yet implemented formal internal controls over mineral resource or reserve estimation but expects to do so as exploration advances. The amendment does not change any previously reported financial results. As of June 30, 2025, non-affiliate equity value was approximately $38.3 million based on a $1.18 share price, and as of June 15, 2026, there were 58,574,115 shares of common stock outstanding.
Odyssey Marine Exploration, Inc. files its annual report describing a seafloor mineral exploration business focused on phosphate sands, polymetallic nodules and subsea gold projects. The company highlights a $37.1 million NAFTA arbitral award plus interest against Mexico tied to its Mexican phosphate project, though Mexico is seeking to set aside the award in Canadian court.
Odyssey reports recurring operating losses of $12.4 million in 2025 and $12.0 million in 2024 and its auditors note substantial doubt about its ability to continue as a going concern. The filing details prior financial restatements, a remediated material weakness in internal control, and a strategy that depends on advancing joint ventures such as the Phosagmex fertilizer project, Cook Islands critical minerals interests, and the Lihir Gold exploration license.
