Marex and certain of its executives are charged with failing to disclose material information during the Class Period, violating federal securities laws.

On August 5, 2025, NINGI Research reported numerous allegations about the Company including, among other things, that it “has engaged in a multi-year accounting scheme involving a web of opaque off-balance-sheet entities, fictitious intercompany transactions, and misleading disclosures to conceal significant losses, inflate profits, and mask its true risk exposure” and that it has “numerous multi-million-dollar discrepancies in intercompany receivables and loans across Marex’s sprawling network of 56+ entities.” The report further identified “a $17 million receivable created out of thin air, a subsidiary whose reported profit was inflated by 150% in group filings before being liquidated, and an asset valued at $14.9 million that was sold to Robinhood for just $2.5 million weeks later, with no reported loss” and that the Company concealed nearly $1 billion in off-balance-sheet derivatives exposure through a Luxembourg fund it both controls and trades with, and that it is using the fund to generate non-cash trading profits and inflate operating cash flow by misclassifying structured note issuance as income.

On this news, the price of Marex’s shares fell $2.33, or 6.2%, to close at $35.31 per share on August 5, 2025, on unusually heavy trading volume.

The case is Narayanan v. Marex Group PLC, et al., No. 25-cv-08393.
