Code of Ethics

We have adopted a Code of Business Conduct and Ethics that applies to all our employees,

officers and directors. Our Code of Business Conduct and Ethics addresses, among other things, conflicts

of interest, confidential information, company assets, confidentiality, compliance with laws and regulations

and corporate opportunity requirements and the process for reporting violations of the Code of Business

Conduct and Ethics. Our Code of Business Conduct and Ethics is intended to meet the definition of “code

of ethics” under Item 16B of 20-F under the Exchange Act.

We will disclose on our website any amendment to, or waiver from, a provision of our Code of

Business Conduct and Ethics that applies to our directors or executive officers to the extent required

under the rules of the SEC or the Nasdaq. Our Code of Business Conduct and Ethics is available on our

website at https://www.marex.com. The information contained on or through our website, or any other

website referred to herein, is not incorporated by reference in this Annual Report.

We granted no waivers under our Code of Business Conduct and Ethics in 2025.
