On August 5, 2025, NINGI Research published a report entitled “Marex Group plc: A Financial House of Cards.” According to the complaint, the NINGI Research report alleges that Marex “has engaged in a multi-year accounting scheme involving a web of opaque off-balance sheet entities, fictitious intercompany transactions, and misleading to conceal significant losses, inflate profits, and mask its true risk exposure.”

Following this news, the price of Marex shares fell $2.33 per share, over 6%, to close at $35.31 per share on August 5, 2025.

The complaint alleges, among other things, that throughout the Class Period, Defendants made false and/or misleading statements and/or failed to disclose that (i) the Company sold over-the-counter financial instruments to itself; and (ii) Marex had inconsistencies in its financial statements between its subsidiaries and related parties, including as to intercompany receivables and loans.
