Changes in Internal Control over Financial Reporting

The Company acquired Curtis on September 18, 2025. As a result of the acquisition, management is in the process of integrating, evaluating and, where necessary, implementing changes in controls and procedures. Other than with respect to the Curtis acquisition, there were no changes in our internal control over financial reporting during the fourth quarter of 2026 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Management's Report on Internal Control over Financial Reporting

Our management, including the principal executive officer and the principal financial officer, is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)). We assessed the effectiveness of our internal control over financial reporting as of June 30, 2026. We have excluded Curtis from our evaluation of internal control over financial reporting as of June 30, 2026 because it was acquired in a business combination during the year. Total assets and total revenue that were excluded from management's assessment represented approximately 4% and 1%, respectively, of consolidated total assets and net sales, as of and for the year ended June 30, 2026. In making this assessment, we used the criteria established by the Committee of Sponsoring Organizations of the Treadway Commission in “Internal Control-Integrated Framework (2013).” We concluded that based on our assessment, the Company's internal control over financial reporting was effective as of June 30, 2026.
