On October 9, 2025, a class action complaint was filed, which alleges that the Company and certain of its senior executives engaged in accounting practices that artificially inflated Marex Group's reported cash flow, revenues, assets, and profits. Plaintiffs allege that these misstatements created an artificial inflation in the price of Marex Group securities. Specifically, the complaint alleges that Marex Group used off-book intercompany transactions to improperly inflate its financial metrics, particularly within its Market Making segment.

The complaint further alleges that the Company recorded debt issuances as operating cash flow and excluded significant off-balance-sheet liabilities tied to internal funds. Additionally, the complaint alleges that the Company failed to disclose structural accounting weaknesses, frequent financial restatements, and prior regulatory findings, including a 2020 Commodity Futures Trading Commission fine for failing to recognize an intercompany loan that concealed the Company's undercapitalization for 33 months.

According to the complaint, these artificially inflated prices caused financial harm to short sellers when the stock price remained elevated due to the alleged fraud.

Investors who sold short Marex Group securities during the Class Period may have important legal rights and are encouraged to act promptly. The deadline to seek appointment as lead plaintiff is December 8, 2025.
