TABLE OF CONTENTS Security Ownership of Certain Beneficial Owners and Management

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE Section 16(a) of the Exchange Act requires the executive officers and directors and persons who beneficially own more than 10% of a class of securities registered under Section 12(b) the Exchange Act to file initial reports of ownership and reports of changes in ownership with the SEC. Such officers, directors and stockholders are required by SEC regulations to furnish us with copies of all such reports that they file. None of our directors or executive officers owns more than 10% of our securities. Based solely upon our review of such forms furnished to us during the fiscal year ended June 30, 2025, and written representations from certain reporting persons, we believe that our executive officers and directors have complied with the requirements imposed on them by Section 16(a) of the Exchange Act, with the exception of two late Form 4 filing by Mr. Ballhaus and one late Form 4 filing by Mr. Hawkins.
