National plaintiffs’ law firm Berger Montague PC announces a class action lawsuit against Marex Group plc on behalf of investors who purchased Marex shares during the period of May 16, 2024 through August 5, 2025 (the “Class Period”).
Investor Deadline: Investors who purchased Marex securities during the Class Period may, no later than December 8, 2025, seek to be appointed as a lead plaintiff representative of the class.
Marex, headquartered in London, is a global financial services firm providing trading, clearing, and risk management solutions.
According to the lawsuit, on August 5, 2025, NINGI Research published a report alleging that Marex 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 true risk exposure.
The report detailed numerous multi-million-dollar discrepancies in intercompany receivables and loans across Marex’s network of over 56 entities. Examples of these discrepancies included a fabricated $17 million receivable, a subsidiary with profits inflated by 150% before liquidation, and an asset valued at $14.9 million sold weeks later for just $2.5 million with no reported loss. The report also alleged nearly $1 billion in off-balance-sheet derivatives exposure concealed through a Marex-controlled fund in Luxembourg was used to generate non-cash trading profits and inflate operating cash flow by misclassifying structured note issuance as income.
Following the issuance of this report, Marex’s stock price fell $2.33, or 6.2%, closing at $35.31 on unusually heavy trading volume, causing investor losses.
