PEABODY ENERGY CORP

Peabody’s disclosure controls and procedures are designed to, among other things, provide reasonable assurance that material information, both financial and non-financial, and other information required under the securities laws to be disclosed is accumulated and communicated to senior management, including the principal executive officer and principal accounting officer, on a timely basis. As of March 31, 2026, the end of the period covered by this Quarterly Report on Form 10-Q, the Company carried out an evaluation of the effectiveness of the design and operation of its disclosure controls and procedures. Based upon that evaluation, Peabody’s Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of the period covered by this report, such disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) were effective to achieve the desired control objectives.

During the first quarter of 2026, the Company completed the first phase of modernizing its enterprise resource planning (ERP) system with further phases planned in 2026. The upgraded ERP system has resulted in, and may continue to result in, changes to existing operational, financial and administrative business processes. The Company believes this will enhance its internal control over financial reporting due to improved operational functionality. In connection with the ERP system modernization, additional internal controls have been implemented and modifications have been made to existing internal control frameworks and procedures, as appropriate.

Except as described above, there have been no other changes to the Company’s internal control over financial reporting during the most recent fiscal quarter that materially affected, or are reasonably likely to materially affect, its internal control over financial reporting.
