Evaluation of Disclosure Controls and Procedures

Our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), with the assistance of other members of management, have performed an evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of June 30, 2026. Based on this evaluation, our CEO and CFO have concluded that as of June 30, 2026, the Company’s disclosure controls and procedures were effective in ensuring that information required to be disclosed in reports that we file or submit under the Exchange Act is (1) recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms, and (2) accumulated and communicated to management, including the chief executive officer and chief financial officer, as appropriate to allow timely decisions regarding required disclosure.

Management’s Report on Internal Control over Financial Reporting

The Company’s management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rule 13a-15(f) of the Exchange Act. 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.

The Company’s 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 the Company’s management and directors; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of assets of the Company that could have a material effect on the financial statements.

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.

Under the supervision, and with the participation, of management, including the CEO and CFO, we conducted an evaluation of the effectiveness of internal control over financial reporting as of June 30, 2026. In making this assessment, management used the criteria established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). Based on this assessment, management, including the Company’s CEO and CFO, has concluded that the Company’s internal control over financial reporting was effective as of June 30, 2026.

The effectiveness of the Company’s internal control over financial reporting as of June 30, 2026 has been audited by Ernst & Young LLP, an independent registered public accounting firm, as stated in their report which appears herein.

Remediation of Previously Identified Material Weakness

As previously reported in Item 9A of our Annual Report on Form 10-K for the fiscal year ended June 30, 2025, and subsequent Quarterly Reports on Form 10-Q during the fiscal year ended June 30, 2026, we disclosed a material weakness related to our controls to review on a timely basis and in sufficient detail the projected financial information and certain key assumptions and underlying calculations used in goodwill and indefinite-lived intangible asset quantitative impairment tests.

During the fiscal year ended June 30, 2026, we implemented and tested remediation measures designed to address the above noted control deficiencies. These measures included enhancing the design of existing controls and implementing additional procedures to independently corroborate in a timely manner the assumptions and inputs used in its projected financial information. Management completed its testing of the design and operating effectiveness of these controls during fiscal year 2026. Based on the successful implementation and testing of these remediation efforts, management concluded that the previously identified material weakness was remediated as of June 30, 2026.

Changes in Internal Control over Financial Reporting

Other than the actions taken to remediate material weakness in internal control over financial reporting, there were no changes in internal controls over financial reporting that occurred during the quarter ended June 30, 2026 that have materially affected, or are reasonably likely to materially affect, internal control over financial reporting.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
