Evaluation of Disclosure Controls and Procedures

Our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act of 1934, as amended (the “Exchange Act”)) are designed to ensure that information required to be disclosed by us in reports we file or submit under the Exchange Act, is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. Our management, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective as of March 31, 2026.

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-15(f) under the Exchange Act). Our 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. 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.

Management assessed, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, the effectiveness of our internal control over financial reporting as of March 31, 2026. In making this assessment, management used the criteria issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in the 2013 “Internal Control-Integrated Framework.” Based on this assessment, management concluded that our internal control over financial reporting was effective as of March 31, 2026.

PricewaterhouseCoopers LLP, our independent registered public accounting firm, has audited the effectiveness of our internal control over financial reporting as of March 31, 2026, as stated in their report which appears in Part II, Item 8 of this Annual Report on Form 10-K.

Remediation of Previously Identified Material Weakness

The material weakness related to not designing and maintaining effective controls over the review and execution of certain balance sheet account reconciliations which was previously identified as of March 31, 2024 and initially reported in our Annual Report on Form 10-K for Fiscal 2024, has been remediated. During Fiscal 2026, we completed the design and implementation of new control activities to ensure balance sheet account reconciliations are appropriately reviewed and executed. Specifically, during the three months ended March 31, 2026, we completed our testing and evaluation of the newly designed and implemented controls and determined that as of March 31, 2026, the controls have been in place and have operated effectively for a sufficient period of time for management to conclude the material weakness has been remediated.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the quarter ended March 31, 2026 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
