LSI INDUSTRIES INC

The Management of LSI Industries Inc. and subsidiaries (the “Company” or “LSI”) is responsible for the preparation and accuracy of the financial statements and other information included in this report. LSI’s Management is also responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Securities Exchange Act Rules 13a-15(f). Under the supervision and with the participation of Management, including LSI’s principal executive officer and principal financial officer, the Company conducted an evaluation of the effectiveness of internal control over financial reporting as of June 30, 2026, based on the criteria set forth in “the 2013 Internal Control – Integrated Framework” issued by the Committee of Sponsoring Organizations of the Treadway Commission.

A control system, no matter how well conceived and operated, can provide only reasonable assurance that the objectives of the control system are met. Because of 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, have been detected. These inherent limitations include the reality that judgments in decision making can be faulty, the possibility of human error, and the circumvention or overriding of the controls and procedures.

In meeting its responsibility for the reliability of the financial statements, the Company depends upon its system of internal accounting controls. The system is designed to provide reasonable assurance that assets are safeguarded and that transactions are properly authorized and recorded. The system is supported by policies and guidelines, and by careful selection and training of financial management personnel. The Company also has a Disclosure Controls Committee, whose responsibility is to help ensure appropriate disclosures and presentation of the financial statements and notes thereto. Additionally, the Company has an Internal Audit Department to assist in monitoring compliance with financial policies and procedures.

The Board of Directors meets its responsibility for overview of the Company’s financial statements through its Audit Committee which is composed entirely of independent Directors who are not employees of the Company. The Audit Committee meets periodically with Management and Internal Audit to review and assess the activities of each in meeting their respective responsibilities. Grant Thornton LLP has full access to the Audit Committee to discuss the results of their audit work, the adequacy of internal accounting controls, and the quality of financial reporting.

The Company acquired Royston Group (Royston) on March 24, 2026. Management excluded Royston from its evaluation of the effectiveness of internal control over financial reporting as of June 30, 2026. Including goodwill and acquired intangible assets, Royston represented 50% of the Company’s total consolidated assets as of June 30, 2026, and 11% of the Company’s total consolidated sales for the fiscal year ended June 30, 2026.

Based upon LSI’s evaluation, the Company’s principal executive officer and principal financial officer concluded that internal control over financial reporting was effective as of June 30, 2026. We reviewed the results of Management’s assessment with the Audit Committee of our Board of Directors. Additionally, our independent registered public accounting firm audited and independently assessed the effectiveness of the Company’s internal control over financial reporting. Grant Thornton LLP, an independent registered public accounting firm, has issued an opinion on the effectiveness of the Company’s internal control over financial reporting, which is presented in the financial statements.
