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.
