NEW YORK, Oct. 20, 2025 (GLOBE NEWSWIRE) — Lowey Dannenberg P.C., a preeminent law firm in obtaining redress for consumers and investors, announces the filing of a class action lawsuit against Marex Group PLC (“Marex” or the “Company”) (NASDAQ: MRX) for violations of the federal securities laws on behalf of investors who purchased or acquired Marex securities between May 16, 2024 and August 5, 2025, inclusive (the “Class Period”).

On October 9, 2025, a complaint was filed against the Company and certain of its current officers, alleging that throughout the Class Period, Defendants made false and/or misleading statements and/or failed to disclose 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.

When investors learned the truth, Marex’s common stock declined precipitously, injuring investors.
