Evaluation of Disclosure Controls and Procedures

The term “disclosure controls and procedures” is defined in Rule 13a-15(e) of the Exchange Act, as “controls and other procedures of an issuer that are designed to ensure that information required to be disclosed by the issuer in the reports that it files or submits under the Act is recorded, processed, summarized and reported, within the time periods specified in the SEC rules and forms.” The Company’s disclosure controls and procedures are designed to ensure that material information relating to the Company and its consolidated subsidiaries is accumulated and communicated to its management, including its Chief Executive Officer and its Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosures.

The Company’s management, with the participation of its Chief Executive Officer and Chief Financial Officer, conducted an evaluation of the effectiveness of its disclosure controls and procedures as of December 31, 2025. Based upon that evaluation, the Company’s Chief Executive Officer and Chief Financial Officer have concluded that the Company’s disclosure controls and procedures were effective as of December 31, 2025, to provide reasonable assurance that information required to be disclosed in the reports that are filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified by the rules and forms of the Exchange Act, and that such information is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the benefits of possible controls and procedures relative to their costs.

Management’s Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting. As defined in Rules 13a-15(f) and 15d(f) under the Exchange Act, internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of the Company’s financial reporting and the preparation of financial statements for external purposes in accordance with U.S. GAAP. Because of its inherent limitations, the Company’s internal control over financial reporting may not prevent or detect all misstatements, including the possibility of human error, the circumvention or overriding of controls, or fraud. Effective internal control can provide only reasonable assurance with respect to the preparation and fair presentation of financial statements.

Management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2025 based on the criteria established by the Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO Framework”).

As a result of management’s review of the Company’s financial and accounting records and the other work completed by the management team and its advisers, management concluded that, as of December 31, 2025, the Company’s internal control over financial reporting was effective.

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.
