TAMPA, Fla., November 12, 2025--(BUSINESS WIRE)--Odyssey Marine Exploration, Inc. (NASDAQ: OMEX), a U.S.-based ocean exploration and marine resource development leader, reported results today for the third quarter ended September 30, 2025, and provided an update on current projects and future plans. "Odyssey is turning strategy into action," said Mark Gordon, Chairman and CEO. "Our plan is straightforward: build a geologically and geographically diverse portfolio to serve multi-year demand for critical minerals. Currently spanning phosphate, polymetallic nodules, and other strategic deposits, our portfolio offers investors exposure to multiple mineral systems, jurisdictions, and development pathways and is designed for continued growth. We are advancing projects that strengthen transparent, reliable supply chains for battery materials, agriculture and food security, and manufacturing—translating this vision into tangible, long-term value through responsible, science-led operations." Recent milestones (Q3 and Early Q4) Concessions confirmed: A Mexican court issued orders annulling the earlier cancellations of our subsidiary’s concessions, thereby restoring the legal validity of the concessions. Subject to the court’s resolution of certain concession-fee matters, the concessions will be assigned to PHOSAGMEX, our Mexican joint venture with Capital Latinoamericano (CapLat), which is focused on strengthening North American fertilizer supply and sustainable agricultural practices. U.S. request for a lease sale submitted: Advanced our U.S. strategy with the submission of an unsolicited request for a lease sale to the Bureau of Ocean Energy Management (BOEM) for a Mid-Atlantic Outer Continental Shelf area prospective for phosphate, titanium, zirconium and rare earth elements—aligning directly with U.S. resource-security priorities. Technical execution in the Cook Islands: Deployed two Autonomous Benthic Mini Landers (ABMLs) in the Cook Islands Exclusive Economic Zone to collect geophysical and environmental data at 5,000 meters’ depth—demonstrating our technical and scientific leadership in deep-ocean resource exploration. Balance sheet simplified: $20.0 million of the Company’s debt was converted into common stock, eliminating all the outstanding obligations under our promissory notes and enhancing liquidity. Industry engagement: Joined the National Ocean Industries Association (NOIA), the leading trade association representing the U.S. offshore energy and ocean industries, expanding Odyssey’s platform for collaboration, policy dialogue, and responsible development across the offshore economy. Odyssey CEO and Chairman Mark Gordon will present at the Emerging Growth Conference on December 10, 2025, at 4:10 PM EST. Interested individual and institutional investors, analysts, and advisors are invited to register to attend live or gain access to the archived webcast.

TAMPA, Fla., August 20, 2025--(BUSINESS WIRE)--Odyssey Marine Exploration, Inc. (NASDAQ: OMEX), an ocean exploration pioneer engaged in the discovery, development, and extraction of subsea strategic minerals that provide solutions to global challenges, today announced its results for the second quarter ended June 30, 2025, and provided updates on key operational and strategic initiatives. "The recognition of ocean minerals as a sustainable source of critical minerals essential to the global economy, food security, and energy transition has accelerated this year with United States (U.S.) leadership now driving global momentum. This marks a breakthrough moment for Odyssey and for the entire ocean mineral resource sector - the time for responsible ocean mineral exploration to advance is now here," said Mark Gordon, Odyssey Chief Executive Officer and Chairman of the Board of Directors. "The recent cooperation agreement between the U.S. and the Cook Islands underscores this momentum and, more specifically, our approach to working directly with governments with a strong regulatory framework and foresight to see the potential of ocean resources to strengthen their economies. Odyssey has been positioning itself for the past 15 years to help create and remain at the forefront of this emerging industry. Now that our debt is materially reduced, operations are fully funded into next year, and we have the flexibility to invest further in high-value projects, Odyssey is stronger than ever. With a diversified portfolio and growing policy support, we expect to now realize the benefits of our years-long efforts, leveraging this strong momentum." Funding and Capital Structure Update Odyssey has significantly strengthened its financial position since announcing its first-quarter results. Existing investors exercised options and warrants during the second quarter, generating approximately $8.2 million in cash proceeds to fund operations. Additionally, holders of the company’s convertible notes converted more than $9.6 million of indebtedness, representing over 53% of the outstanding note obligations. These transactions not only secure working capital to fund operations into 2026 and reduce the company’s debt but also highlight growing investor confidence in Odyssey’s execution and the broader recognition that subsea minerals represent an outstanding investment opportunity in the current environment. Cook Islands Polymetallic Nodule Project Update On August 4, 2025, the United States and the Cook Islands announced a new cooperation agreement to advance scientific research and the responsible development of seabed mineral resources. Odyssey plays a key role in this effort, holding equity in and providing services to two of the three licensed exploration programs [CIC Limited and Ocean Minerals LLC (OML)] within the Cook Islands’ Exclusive Economic Zone (EEZ), which hosts an estimated 12 billion wet tonnes of polymetallic nodules. This growing alignment between the U.S. and the Cook Islands governments reinforces the global importance of these resources and highlights Odyssey’s role as a key technical and operational partner in one of the world’s most promising seabed mineral regions. As part of its ongoing operations, Odyssey recently deployed two Autonomous Benthic Mini Landers (ABMLs) in the Cook Islands. These advanced systems are engineered to collect critical environmental data from depths of 5,500 meters—data essential for designing and implementing responsible mineral programs. OML recently obtained a Joint Ore Reserve Committee (JORC) compliant report that substantially increases resources reporting to inferred and indicated confidence levels, and continues to advance toward completing OML’s preliminary Feasibility Study, among other important project milestones it is working to achieve. The independent assessment indicates the license area contains approximately 519 million metric tonnes of indicated and inferred polymetallic nodules, including an inferred resource of about one million tonnes of contained cobalt—believed to be the largest primary cobalt resource in the world. The nodules also host significant quantities of manganese, nickel, and rare earth elements, underscoring the strategic importance of this deposit. The summary of OML’s resource assessment is available on its website: www.omlus.com. Information available on OML’s website, including its technical report summary, is not incorporated into our second quarter Form 10-Q. U.S. Policy Update On April 24, 2025, an Executive Order directed U.S. federal agencies to accelerate the responsible exploration and development of offshore critical minerals, strengthen domestic supply chains, and reestablish U.S. leadership in seabed resource technologies. Odyssey is well positioned to benefit from this policy shift, with active projects focused on ocean minerals essential to agriculture and clean energy technology. Odyssey has been qualified by the U.S. Bureau of Ocean Energy Management (BOEM) to acquire and hold a marine minerals lease since 2021, and we will consider submitting lease applications based on the new permitting framework as it emerges because of the Executive Order. PHOSAGMEX JV Update During the quarter, Odyssey marked a significant milestone in the formation and advancement of PHOSAGMEX, its joint venture with Capital Latinoamericano, focused on enhancing North American food security through a sustainable, domestically sourced fertilizer supply. The venture builds on extensive research confirming the presence of a high-quality phosphate resource within Mexico’s EEZ. The project aligns with Mexico’s broader initiative to achieve food and agriculture self-sufficiency by supporting sustainable farming, empowering producers, and driving local economic development. As part of this progress, Odyssey has initiated the transfer of legal rights for mining concessions into the joint venture and anticipates continued project development in the coming months.
