Management’s Report on Internal Controls Over Financial Reporting

The Company's management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule 13a-15(f) of the Exchange Act. Because of its inherent limitations, internal control over financial reporting may not prevent or detect all misstatements or fraud. Any control system, no matter how well designed and operated, is based upon certain assumptions and can provide only reasonable, not absolute, assurance that its objectives will be met. Management, with the participation of its principal executive officer and principal financial officer assessed the effectiveness of the Company's internal control over financial reporting based on the criteria for effective internal control over financial reporting established in "Internal Control—Integrated Framework (2013)," issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based upon its assessment, management concluded that the Company maintained effective internal control over financial reporting as of February 28, 2026.

The Company’s independent registered public accounting firm, Grant Thornton, LLP, has issued an audit report on the Company’s internal control over financial reporting, which is included in "Item 8. Financial Statements and Supplementary Data" of this Form 10-K.
