Odyssey Marine Exploration, Inc. (OMEX) entered into an Amendment to its Note Purchase Agreement with American Ocean Minerals Corporation (AOM) on September 8, 2026, modifying existing secured financing arrangements between the parties while they pursue a pending merger. Under the original Note Purchase Agreement dated April 8, 2026, Odyssey issued and sold to AOM secured promissory notes in an aggregate principal amount of up to $5.0 million between May and July 2026, with AOM also having the option to purchase additional secured “Pre-Closing Notes” in an aggregate principal amount of up to $5.0 million. AOM purchased one such Pre-Closing Note on May 28, 2026 in the principal amount of $700,000. The notes are secured by a security interest in substantially all of Odyssey’s assets, bear interest at 8.0% per annum capitalized quarterly, and all principal and accrued interest are due on the earlier of April 8, 2027 or consummation of the proposed merger with AOM; upon an event of default on interest payments, amounts accrue interest at 11.0% per annum.
Odyssey Marine Exploration, Inc. reported that Nasdaq notified the company its common stock no longer met the $1.00 minimum bid price requirement for 30 consecutive business days under Nasdaq Listing Rule 5550(a)(2).

Odyssey Marine Exploration is pursuing an all-stock merger with American Ocean Minerals Corporation to create what management describes as a large U.S.-controlled deep-sea critical minerals platform. The combined company would focus on polymetallic nodules containing nickel, cobalt, copper, manganese, and rare-earth elements.
The transaction is framed as a roughly billion‑dollar merger, supported by more than $230 million of equity capital, including an oversubscribed $156 million PIPE and $75 million of bridge financing. A 25‑to‑1 reverse stock split is planned before closing, and the combined entity is expected to trade on NASDAQ under the ticker AOMC.
Management highlights over 500,000 square kilometers of licensed and targeted areas, dual regulatory pathways through the Cook Islands and U.S. frameworks, and SK 1300–compliant resources exceeding 2 billion tons inferred in one license area and 417 million tons indicated in another. They emphasize existing deep‑sea operating experience, policy tailwinds for critical minerals, and a capital‑light, phased processing strategy, while cautioning that the merger remains subject to stockholder approvals, regulatory processes, and other customary closing conditions.
Odyssey Marine Exploration agreed to an all-stock merger with American Ocean Minerals Corporation, creating a deep-sea critical minerals platform valued at approximately $1 billion. AOM stockholders will receive 4.5017 shares of Odyssey common stock per AOM share, with certain holders instead receiving convertible preferred shares to keep ownership below 4.99%.
The deal includes assumption of AOM PIPE warrants, a planned 25-for-1 reverse stock split, and an increase in authorized Odyssey common shares from 75 million to 750 million, subject to stockholder approval. AOM has arranged approximately $75.6 million of bridge financing and a $156.0 million PIPE, while Odyssey may issue up to $10.0 million of secured notes at 8.0% interest.
Odyssey plans to divest its Mexican phosphate business into a liquidating trust for existing shareholders, which is expected to remove about $60 million of related liabilities, and the combined company is expected to have more than $175 million in cash after closing. Multiple option and note agreements with Cook Islands–focused entities and Ocean Minerals LLC aim to consolidate large polymetallic nodule resources under a U.S.-controlled supply chain.
Odyssey Marine Exploration entered into an amended and restated joint venture agreement with Capital Latinoamericano and their affiliates to continue developing a strategic fertilizer production project in Mexico through Phosagmex.

Prior steps included initial capital contributions by both parties and an agreement for ExO to assign specified mining concessions to Phosagmex if those concessions are reinstated.
