Who are the reporting persons in the OMEX Schedule 13G/A filing?
The reporting persons are FourWorld Capital Management LLC and John Addis, described collectively as the Filers. FourWorld Capital is organized in Delaware and Addis is a U.S. citizen, with their principal business address at 7 World Trade Center, Floor 46, New York, NY 10007.
Are FourWorld Capital’s OMEX shares held directly by the firm or its clients?
The filing states that the securities reported as beneficially owned by FourWorld Capital are directly owned by its advisory clients. Other than the reporting persons, none of these clients individually owns more than 5% of Odyssey Marine’s outstanding common stock.
Does FourWorld Capital intend to influence control of Odyssey Marine (OMEX)?
The filers certify the securities were acquired and are held in the ordinary course of business and not for the purpose or effect of changing or influencing control of Odyssey Marine, nor in connection with any transaction intended to have that purpose or effect.
What voting and dispositive powers over OMEX shares are reported in this filing?
Both FourWorld Capital and John Addis report 0 shares with sole voting or dispositive power and 455,571 shares with shared voting and shared dispositive power. This means decisions on these shares are made jointly rather than by either filer alone.
Why does this OMEX Schedule 13G/A note ownership of 5 percent or less?
Item 5 confirms ownership of 5 percent or less of the class, consistent with the reported 0.8% stake. This indicates the position is below the traditional 5% threshold associated with larger, potentially more influential shareholders.
