MRX DEADLINE: ROSEN, A RANKED AND LEADING LAW FIRM, Encourages Marex Group plc Investors to Secure Counsel Before Important Deadline in Securities Class Action – MRX

NEW YORK (Nov. 16, 2025) — The Rosen Law Firm, P.A., a global investor‑rights law firm, is alerting purchasers of Marex Group plc (NASDAQ: MRX) securities who bought shares between May 16, 2024 and August 5, 2025 (inclusive) of a critical deadline: December 8, 2025. If you acquired Marex securities during that “Class Period”, you may be eligible to participate in a class action without paying any out‑of‑pocket fees—through a contingency fee arrangement. To join the lawsuit, investors can submit the online form (case ID: 43100), call toll‑free, or email the firm. If you wish to serve as lead plaintiff you must file a motion with the court no later than December 8, 2025. Why Rosen? The firm emphasises the importance of selecting experienced counsel with a proven track record, warning that many firms issuing such notices may lack meaningful experience in securities class litigation. Regarding the case itself: According to the complaint, during the Class Period Marex allegedly: (1) sold over‑the‑counter financial instruments to itself; (2) reported inconsistent financial statements between its subsidiaries and related parties (including inter‑company receivables and loans); (3) issued financial statements that could not be relied upon; and (4) made materially misleading positive statements about its business, operations and prospects. When the true details emerged, investors allegedly suffered damages. The class has not yet been certified; until such certification, participants are not represented by counsel unless they retain one themselves. Choosing not to act now may still allow you to remain an absent class member and share in any potential recovery, but serving as lead plaintiff may offer greater influence. Contact details for The Rosen Law Firm are provided for those seeking additional information or wanting to participate. #MarexGroup #SecuritiesClassAction #InvestorRights #MRXDeadline #SlimScan #GrowthStocks #CANSLIM
