CONSOLIDATED FINANCIAL STATEMENTS

MANAGEMENT’S REPORT ON INTERNAL CONTROL

The Company has assessed the effectiveness of its internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) (2013 framework). The Company’s management is responsible for establishing and maintaining adequate internal controls over financial reporting. The effectiveness of the Company’s internal control over financial reporting as of December 31, 2025, has been audited by the Company’s independent registered public accounting firm, as stated in their report that is included herein.

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. Internal control over financial reporting includes those policies and procedures that: (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of the 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.

The Company’s assessment of the effectiveness of its internal control over financial reporting included testing and evaluating the design and operating effectiveness of its internal controls. In management’s opinion, the Company has maintained effective internal control over financial reporting as of December 31, 2025, based on criteria established in the COSO 2013 framework.
