The Schall Law Firm, a national shareholder rights litigation firm, announces that it is investigating claims on behalf of investors of Marex Group plc (“Marex” or “the Company”) (NASDAQ: MRX) for violations of the securities laws.

The investigation focuses on whether the Company issued false and/or misleading statements and/or failed to disclose information pertinent to investors. Marex is the subject of a report published on NINGI Research on August 5, 2025, titled: "Marex Group plc: A Financial House of Cards." According to the report, the Company “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. We have uncovered evidence suggesting Marex is a financial house of cards, with a balance sheet riddled with holes and financials that we believe are unreliable." Based on this news, shares of Marex fell by almost 6.2% on the same day.
