Internal Control over Financial Reporting

The SEC, as required by Section 404 of the Sarbanes-Oxley Act of 2002, adopted rules that generally require every company that files reports with the SEC to evaluate its effectiveness of internal controls over financial reporting.

Management has conducted an evaluation of the effectiveness of the Company's internal control over financial reporting based on the criteria set forth in Internal Control-Integrated Framework (2013)issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on the results of this evaluation, management concluded that the Company’s internal control over financial reporting was effective as of December 31, 2025. Management’s report is included on page F-1 of this Annual Report on Form 10-K. KPMG LLP, an independent registered public accounting firm, has made an independent assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2025, and their report is included on page F-4 of this Annual Report on Form 10-K.

There were no changes in the Company’s internal controls over financial reporting that occurred during the fourth quarter of 2025 that have affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
