Smart Money Convergence

OMEX does not currently have enough recent insider (Form 4) trading activity to compute a convergence signal against its 13F institutional flows.

13F data as of 2026-06-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.

Odyssey Marine Exploration (OMEX) received a Nasdaq deficiency notice on July 21, 2026, because its stock failed to maintain a minimum bid price of $1.00 for 30 consecutive business days. The company has until January 19, 2027, to regain compliance by closing at $1.00 or higher for ten straight days. If it doesn't, it may qualify for an additional 180-day period. Notably, shareholders already approved a reverse stock split (1:20 to 1:25) that the company expects will help it meet the listing requirement before its planned merger with American Ocean Minerals Corporation.
