[Form 4] Odyssey Marine Exploration, Inc Insider Trading Activity

Rhea-AI Filing Summary

On August 14, 2025 the issuer, Odyssey Marine Exploration, Inc. (OMEX), issued a total of 6,056,073 shares of common stock, bringing the outstanding share count to 45,190,598. As reported on Form 4 filed by director Juan Antonio Carlos Cortina Gallardo, the director beneficially owned 3,931,466 common shares indirectly through Promotora de Inversiones CapLat Espana, S.L. The new issuance reduced the director's stake to below 10% of outstanding shares, and the reporting person states they are no longer subject to Section 16 reporting obligations solely because of that issuance.

Insights

Securities Analyst

TL;DR: Share issuance increased outstanding shares and reduced a director's ownership below 10%, altering Section 16 reporting status but not indicating a sale by the director.

The Form 4 discloses an indirect holding of 3,931,466 shares by the director via an entity and notes the issuer issued 6,056,073 shares, lifting total outstanding to 45,190,598. This change is material from a regulatory-compliance perspective because it removes the director from the >10% reporting threshold. There is no indication the director sold shares; the change in percentage ownership resulted from the issuer's dilution. Investor impact is primarily administrative, though dilution modestly reduces existing ownership percentages.

Corporate Governance Expert

TL;DR: The filing documents a regulatory-status change for a director due to issuer dilution; it raises governance transparency but no misconduct.

The signature-dated Form 4 clarifies that the director's Section 16 obligations cease solely because the issuer increased share count. The report specifies indirect ownership via Promotora de Inversiones CapLat Espana, S.L., and includes a manual signature. From a governance viewpoint, the filing is procedurally correct and informative; it does not disclose related-party transactions, sales, or new insider purchases.

Explanation of Responses:

1. On August 14, 2025, the issuer filed a Form 8-K reporting the issuance of an aggregate of 6,056,073 shares of the issuer's common stock and that following the issuances the issuer had 45,190,598 shares of common stock outstanding. Solely as a result of the events disclosed in the Form 8-K, the reporting person no longer holds ten percent or more of the issuer's outstanding common stock and is therefore no longer subject to Section 16 reporting requirements.
