What Happened?

On August 5, 2025, NINGI Research published a report alleging, among other things, that Marex “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.” The report alleged, among other things, that the Company has “numerous multi-million-dollar discrepancies in intercompany receivables and loans across Marex’s sprawling network of 56+ entities.” The report identified examples, including “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.” The report further alleged 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, Marex’s stock price fell $2.33, or 6.2%, to close at $35.31 per share on August 5, 2025, on unusually heavy trading volume.

What Is The Lawsuit About?

The complaint filed in this class action alleges that throughout the Class Period, Defendants made materially false and/or misleading statements, as well as failed to disclose material adverse facts about the Company’s business, operations, and prospects. Specifically, Defendants failed to disclose to investors that: (1) the Company sold over-the-counter financial instruments to itself; (2) Marex had inconsistencies in its financial statements between its subsidiaries and related parties, including as to intercompany receivables and loans; (3) as a result of the foregoing, Marex’s financial statements could not be relied upon; and (4) that, as a result of the foregoing, Defendants’ positive statements about the Company’s business, operations, and prospects were materially misleading and/or lacked a reasonable basis.

If you purchased or otherwise acquired Marex securities during the Class Period, you may move the Court no later than 60 days from the date of this notice to ask the Court to appoint you as lead plaintiff.
