Odyssey Marine Exploration stock: 1-for-25 split tied to merger

Odyssey Marine Exploration said on October 16, 2026, that the U.S. Securities and Exchange Commission had declared effective its Form S-4 registration statement for the proposed merger with American Ocean Minerals Corporation. The company also announced a planned 1-for-25 reverse stock split. The details were published in a company announcement from Odyssey Marine Exploration.

Merger process moves toward vote

The registration statement became effective on October 15, 2026. Odyssey filed a definitive proxy statement and prospectus and plans to hold a special meeting on December 2, 2026, at 10:00 a.m. Eastern Time. Investors will vote on proposals connected with the merger, including the proposed issuance of Odyssey common stock under applicable Nasdaq listing rules.

The transaction has not been completed. Odyssey said the merger with American Ocean Minerals remains subject to shareholder approval and the satisfaction or waiver of other closing conditions. If completed, the company is expected to be renamed American Ocean Minerals Corporation, with the combined company's shares expected to trade on Nasdaq under the symbol AOMC.

Reverse split mechanics

Under the announced plan, the reverse split is scheduled to take effect on October 29, 2026, with split-adjusted trading expected to begin on that date. The company said the measure is intended to increase the trading price and reduce shareholder transaction costs. It also said completion of the split is a condition for certain investors' financing commitments for the combined business.

For holders of record on October 26, every twenty-five pre-split shares would be combined into one share. Odyssey estimated that outstanding common stock would fall from approximately 58.6 million shares to approximately 2.3 million shares. The split would not change a holder's percentage ownership, apart from adjustments related to fractional shares.

Investor context

Odyssey describes itself as a U.S.-based ocean exploration and marine mineral development company with more than 30 years of subsea operating experience. The proposed combination is intended to create a U.S.-based platform focused on offshore critical minerals, but the company's stated completion conditions remain material for investors assessing the timeline.
