 limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. Management, under the supervision and with the participation of its Chief Executive Officer and Chief Financial Officer, carried out an evaluation of the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e)) as of December 31, 2024. Based upon that evaluation, the Company’s Chief Executive Officer and Chief Financial Officer concluded that, as of December 31, 2024, the Company’s disclosure controls and procedures were effective. Management’s report on internal control over financial reporting Management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a-15(f) of the Exchange Act. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies and procedures may deteriorate . Management assessed the effectiveness of internal control over financial reporting as of December 31, 2024 based upon the framework in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). Based on this assessment, management concluded that ArcelorMittal’s internal control over financial reporting was effective as of December 31, 2024. The effectiveness of management’s internal control over financial reporting as of December 31, 2024 has been audited by the Company’s independent registered public accounting firm, Ernst & Young S.A., and their report as of March 10, 2025 below expresses an unqualified opinion on the Company’s internal control over financial reporting. Remediation of Previously Disclosed Material Weakness A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company's financial statements will not be prevented or detected on a timely basis.
