Evaluation of Disclosure Controls and Procedures

The Registrants, through the oversight of FirstEnergy's Disclosure Committee, have established disclosure controls and procedures to ensure that information is accumulated and communicated to management, including their respective principle executive officer and principle financial officer, as appropriate to allow timely decisions regarding required disclosure, and ensure that information required to be disclosed in the reports the Registrants file or submit under the Exchange Act, are recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms.

The management of the Registrants, with the participation of their respective principal executive officer and principal financial officer, have established and evaluated the effectiveness of their disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Based on that evaluation, the principal executive officers and principal financial officers of the Registrants have concluded that the disclosure controls and procedures in place were effective as of the end of the period covered by this report.

Management’s Report on Internal Control over Financial Reporting

Management of FirstEnergy is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. FirstEnergy’s 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 or procedures may deteriorate.

Management conducted an evaluation of the effectiveness of FirstEnergy's internal control over financial reporting as of December 31, 2025, based on the framework in "Internal Control-Integrated Framework" (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on that evaluation, management concluded that FirstEnergy's internal control over financial reporting was effective as of December 31, 2025.

The effectiveness of FirstEnergy's internal control over financial reporting as of December 31, 2025 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report, which is included herein.

This Annual Report does not include a report of JCP&L’s assessment regarding internal control over financial reporting due to the transition period established by the rules of the SEC for newly public companies.

Changes in Internal Control over Financial Reporting

During the quarter ended December 31, 2025, there were no changes in internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that have materially affected, or are reasonably likely to materially affect, the Registrants’ internal control over financial reporting.
