Evaluation of Disclosure Controls and Procedures

Evaluation of Disclosure control and Procedures. We carried out an evaluation, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, of the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) to ensure that information required to be disclosed in reports filed under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the required time periods and is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

Based upon that evaluation, our principal executive officer and principal financial officer concluded that, as of September 27, 2025, the period covered in this report, our disclosure controls and procedures were not effective because of the material weaknesses discussed below.

In light of the conclusion that our internal disclosure controls are ineffective as of September 27, 2025, we have applied procedures and processes as necessary to ensure the reliability of our financial reporting in regard to this Quarterly Report. Accordingly, the Company believes, based on its knowledge, that: (i) this Quarterly Report does not contain any untrue statement of a material fact or omit a material fact; and (ii) the financial statements, and other financial information included in this Quarterly Report, fairly present in all material respects our financial condition, results of operations and cash flows as of and for the periods presented in this Quarterly Report.

Management’s Report on Internal Control Over Financial Reporting. Our management 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)). Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our management assessed the effectiveness of our internal control over financial reporting as of September 27, 2025. In making this assessment, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in 2013 regarding Internal Control – Integrated Framework. Based on our assessment using those criteria, our management concluded that our internal control over financial reporting was not effective as of September 27, 2025.

Management noted material weaknesses in internal control when conducting their evaluation of internal control as of September 27, 2025. (1) Insufficient written documentation of our internal control policies and procedures. Written documentation of key internal controls over financial reporting is a requirement of Section 404 of the Sarbanes-Oxley Act; and (2) Insufficient resources to maintain adequate segregation of duties and maintain its internal control environment.

These material weaknesses remained outstanding as of the filing date of this Form 10-Q and management is currently working to remedy these outstanding material weaknesses.

The Company’s management, including the Company’s CEO and CFO, does not expect that the Company’s disclosure controls and procedures or the Company’s internal controls over financial reporting will prevent or detect all error and all fraud. A control system, regardless of how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system will be met. These inherent limitations include the following: judgments in decision-making can be faulty, and control and process breakdowns can occur because of simple errors or mistakes, controls can be circumvented by individuals, acting alone or in collusion with each other, or by management override, the design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions, over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures. 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.

Changes in Internal Control Over Financial Reporting. There were no changes in the Company’s internal control over financial reporting during the fiscal year ended September 27, 2025 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
