(a) Disclosure Controls and Procedures. Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this report. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of such period, our disclosure controls and procedures are effective.

(b) Internal Control Over Financial Reporting. The Company's management, with the participation of the Company's Chief Executive Officer and Chief Financial Officer, evaluated any change in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) and determined that there was no change in our internal control over financial reporting during the quarter to which this report relates that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. We completed the Bren-Tronics acquisition on July 26, 2024 and are in the process, but have not yet concluded our assessment of the effectiveness of our internal control over financial reporting including this recent acquisition. Accordingly, pursuant to the SEC's general guidance that an assessment of a recently acquired business may be omitted from the scope of an assessment in the year of acquisition, the scope of our assessment of the effectiveness of our disclosure controls and procedures does not include Bren-Tronics. For both the second quarter and six months of fiscal 2026, Bren-Tronics accounted for approximately 3% of sales and as of September 28, 2025 approximately 5% of total assets.
