Evaluation of Disclosure Controls and Procedures

Our management, including our Principal Executive Officer and Principal Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures pursuant to Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act") as of the end of the annual period covered by this report. Based on that evaluation, our Principal Executive Officer and Principal Financial Officer concluded that, as of August 31, 2026, our disclosure controls and procedures were effective.

Remediation of Previously Reported Material Weakness

As first reported in our Annual Report on Form 10-K for the fiscal year ended August 31, 2024, we identified deficiencies in the design and operation of IT general controls that support our revenues, accounts receivable, and deferred revenues processes which, in the aggregate, gave rise to a material weakness in internal control over financial reporting. Management, with the oversight of the Audit Committee of our Board of Directors, executed a remediation plan, which included:

•Implementing controls that increase the frequency and effectiveness of user access management and change management, including improved logging and segregation of duties capabilities.

•Formalizing standard operating procedures and documentation for change monitoring and segregation of duties review controls and training relevant personnel on the design and operation of our IT general controls.

•Performing additional testing of IT general controls to demonstrate the sustainability and repeatability of control operating effectiveness.

•Implementing technology solutions to enhance the control framework for supporting change monitoring, segregation of duties and access management review controls.

•Hiring additional IT compliance personnel and Chief Audit Executive.

During the year ended August 31, 2026, management completed our testing of these remediation measures. The enhanced controls operated for a sufficient period of time, and management completed testing of their design and operating effectiveness in the fourth quarter. Based on the results of this testing, management concluded that the material weakness was remediated as of August 31, 2026.

Changes in Internal Control over Financial Reporting

Other than completion of the remediation measures described above, there were no changes in the Company’s internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the fourth quarter of fiscal 2026 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
