Changes in Internal Control Over Financial Reporting

The Company completed the Envaplast Acquisition on June 2, 2026. The scope of the Company’s assessment of the effectiveness of internal controls over financial reporting for the fiscal year ending September 30, 2026, will not include the Envaplast Acquisition. This exclusion is in accordance with the SEC’s general guidance that an assessment of a recently acquired business may be omitted from the Company’s scope in the year of acquisition.

We are currently integrating the processes and internal controls of Envaplast. Except for the Envaplast Acquisition, there has been no change in our internal control over financial reporting that occurred during the most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
