Management’s Report on Internal Control over Financial Reporting

The Company’s management is responsible for establishing and maintaining adequate internal control over financial reporting. Under the supervision and with the participation of the Company’s management, including the Chief Executive Officer and Chief Financial Officer, the Company evaluated the effectiveness of the design and operation of its internal control over financial reporting based on the framework in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on that evaluation, the Company’s Chief Executive Officer and Chief Financial Officer concluded that the Company’s internal control over financial reporting was effective as of December 31, 2024.

As discussed in Note 3 to the Consolidated Financial Statements in Item 8, the Company completed the acquisition of MTL Holdings LLC ("MTL") on May 1, 2024 and PFB Holdco ("PFB") on December 18, 2024. Management's assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of MTL or PFB, which represented approximately 8% and 6% of total assets, respectively, as of December 31, 2024, and approximately 2% and less than 1% of revenues, respectively, for the year then ended.

The Company's internal control over financial reporting has been audited by Deloitte & Touche LLP, whose report with respect to the effectiveness of internal control over financial reporting is included in Item 8.
