Evaluation of Disclosure Controls and Procedures

Our management conducted an evaluation, with the participation of our Chief Executive Officer and our Chief Financial Officer, 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 the end of the period covered by this Annual Report on Form 10-K. Based upon that evaluation, our Chief Executive Officer and our Chief Financial Officer concluded that as a result of the material weakness in our internal control over financial reporting described below, our disclosure controls and procedures were not effective as of April 30, 2026 due to the material weakness in internal control over financial reporting described below.

Management’s Annual Report on Internal Control over Financial Reporting

Management is responsible for the preparation of our financial statements and related information. Management uses its best judgment to ensure that the financial statements present fairly, in material respects, our financial position and results of operations in conformity with generally accepted accounting principles.

Management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in the Exchange Act. These internal controls are designed to provide reasonable assurance that the reported financial information is presented fairly, that disclosures are adequate and that the judgments inherent in the preparation of financial statements are reasonable. There are inherent limitations in the effectiveness of any system of internal controls including the possibility of human error and overriding of controls. Consequently, an effective internal control system can only provide reasonable, not absolute, assurance with respect to reporting financial information.

Our internal control over financial reporting includes policies and procedures that: (i) pertain to maintaining records that, in reasonable detail, accurately and fairly reflect our transactions; (ii) provide reasonable assurance that transactions are recorded as necessary for preparation of our financial statements in accordance with generally accepted accounting principles and that the receipts and expenditures of company assets are made in accordance with our management and directors authorization; and (iii) provide reasonable assurance regarding the prevention of or timely detection of unauthorized acquisition, use or disposition of assets that could have a material effect on our financial statements.

Under the supervision of our Chief Executive Officer and our Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) published in 2013 and subsequent guidance prepared by COSO specifically for smaller public companies. Based on that evaluation, our management concluded that our internal control over financial reporting was not effective as of April 30, 2026, for the reasons discussed below.

A material weakness is a deficiency or a combination of deficiencies in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of the annual or interim consolidated financial statements will not be prevented or detected on a timely basis.

Management identified the following material weakness in its assessment of the effectiveness of internal control over financial reporting as of April 30, 2026:

The Company did not maintain effective controls over certain aspects of the financial reporting process because: (i) we lack a sufficient complement of personnel with a level of accounting expertise and an adequate supervisory review structure that is commensurate with our financial reporting requirements, (ii) there is inadequate segregation of duties due to our limited number of accounting personnel, and (iii) we have insufficient controls and processes in place to adequately verify the accuracy and completeness of spreadsheets that we use for a variety of purposes including revenue, taxes, stock-based compensation, earnings per share computations, and other areas, and place significant reliance on, for our financial reporting.

This material weakness contributed to material misstatements to basic and diluted weighted-average shares outstanding and basic and diluted earnings per share (“EPS”) in the Company’s quarterly reports on Form 10-Q for the second and third quarters for the fiscal year ended April 30, 2026, which were corrected in amendments to such filings prior to the issuance of the consolidated financial statements as of and for the year ended April 30, 2026.

We are in the process of taking appropriate and reasonable steps to make the necessary improvements to remediate these deficiencies. As a significant step in the remediation of these deficiencies, effective March 9, 2026, the Company appointed William B. Miller as Chief Financial Officer. Mr. Miller’s appointment separates the principal financial and accounting officer function from the Chief Executive Officer role for future periods and is expected to strengthen the Company’s financial reporting capabilities, supervisory review structure, and segregation of duties. We are committed to taking additional steps to improve our financial organization when we are able including, without limitation, expanding our accounting staff and improving our systems and controls to reduce our reliance on the manual nature of our existing systems. However, due to our size and our financial resources, remediating the several identified weaknesses has not been possible and may not be economically feasible now or in the future.

Our management, including our Chief Executive Officer and our Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Due to the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within our Company have been detected.

We will continue to monitor and evaluate the effectiveness of our internal control over financial reporting on an ongoing basis and are committed to taking further action and implementing additional enhancements or improvements, as necessary and as funds allow. We do not, however, expect that the material weaknesses in our disclosure controls will be remediated until such time as we have improved our internal control over financial reporting.

This Annual Report on Form 10-K does not include an attestation report of our registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by our registered public accounting firm pursuant to rules of the SEC that permit us to provide only management’s report in this Annual Report on Form 10-K.

Changes in Internal Control over Financial Reporting

There were no changes identified in connection with our internal control over financial reporting during the quarter ended April 30, 2026, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting other than the steps we have taken to address material weaknesses described immediately above.
