EXPLANATORY NOTE

This Registration Statement on Form S-8 (this “Registration Statement”) is filed by Marex Group Limited (the “Registrant”) to register an additional 5,459,693 ordinary shares, par value US$0.001551 per share (the “Ordinary Shares”), that may be offered and sold pursuant to the Marex Group Limited Employee Share Purchase Plan and the Marex Group Limited Global Omnibus Plan (collectively, the “Plans”).

The Registrant previously registered shares for issuance under the Marex Group plc Global Omnibus Plan and the Marex Group plc Employee Share Purchase Plan (collectively, the “Prior Plans”) pursuant to the Registration Statement on Form S-8 (Registration No. 333-278953) filed with the Securities and Exchange Commission on April 26, 2024, as amended by the Post-Effective Amendment No. 1 to the Registration Statement (the “Prior Registration Statement”). The Post-Effective Amendment reflects the scheme of arrangement completed by the Registrant and Marex Group plc, a public limited company incorporated under the laws of England and Wales (“Marex plc”), whereby the Registrant became the holding company of Marex plc (the “Reorganization”). Pursuant to the Reorganization, all issued ordinary shares of Marex plc were cancelled and, in consideration for such cancellation, each Marex plc ordinary shareholder as at the scheme record time (6:00 p.m. Eastern Time on June 30, 2026) received, on a one-for-one basis, Ordinary Shares of the Registrant. As a result of the Reorganization, each outstanding equity award under the Prior Plans, and any other right to receive ordinary shares thereunder, was exchanged for an equivalent equity award under the Plans relating to Ordinary Shares of the Registrant on a one-for-one basis.

The additional shares registered pursuant to the Plans are of the same class as other securities relating to the Plans for which the Prior Registration Statement is effective and incorporated by reference herein.
