Investors Can Lead Class Action Against Marex Group plc

A class action lawsuit has been initiated against Marex Group plc, a financial services company, by investors who purchased its securities between May 16, 2024 and August 5, 2025. The case, filed by the Rosen Law Firm, seeks to address allegations of securities fraud, with investors potentially eligible for compensation without upfront costs.

The Rosen Law Firm announced the formation of this class action on October 22, 2025. Investors wishing to serve as lead plaintiffs must submit a motion to the court by December 8, 2025. Those who purchased Marex securities during the specified period may be entitled to recovery through a contingency fee arrangement, which means they would incur no out-of-pocket expenses.

As part of the lawsuit, Rosen Law Firm reports that Marex made several materially false statements and failed to disclose critical information. The allegations include that Marex sold over-the-counter financial instruments to itself and exhibited inconsistencies in its financial statements among subsidiaries and related parties. As a result, the firm claims that Marex’s financial records were unreliable, which misled investors regarding the company’s business operations and prospects.

The firm has a notable track record in securities litigation, having achieved significant settlements for investors in the past. For instance, in 2019, the Rosen Law Firm secured over $438 million for its clients. In 2020, founding partner Laurence Rosen was recognized as a Titan of the Plaintiffs’ Bar by Law360, highlighting the firm’s expertise in navigating complex securities class actions.
