Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures designed to provide reasonable assurance that information required to be disclosed in reports filed with the SEC under the Exchange Act, is recorded, processed, summarized and reported within the specified time periods, and that such information is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of December 30, 2023 pursuant to Rule 13a-15 and 15d-15 of the Exchange Act. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that, as of such date, our disclosure controls and procedures were effective to meet the objectives for which they were designed and operated at the reasonable assurance level.

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 Rule 13a-15(f) under the Exchange Act. We assessed the effectiveness of our internal control over financial reporting as of December 30, 2023, based on the “Internal Control — Integrated Framework (2013)” issued by the Committee of Sponsoring Organizations of the Treadway Commission. This assessment was conducted utilizing our documentation of policies and procedures, risk control matrices, gap analysis, key process walk-throughs and management’s knowledge of and interaction with its controls and testing of our key controls.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projection of any evaluation of effectiveness to future periods is 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.

A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. Based on such assessment and criteria, management has concluded that the internal controls over financial reporting were effective as of December 30, 2023. The effectiveness of our internal control over financial reporting as of December 30, 2023 has been audited by RSM US LLP, an independent registered public accounting firm, as stated in its report which is included immediately following Item 15.Exhibit and Financial Statement Schedules, in this Annual Report on Form 10-K.

Changes in Internal Control Over Financial Reporting

The Company monitors and evaluates on an ongoing basis its internal control over financial reporting in order to improve its overall effectiveness. In the course of these evaluations, the Company modifies and refines its internal processes as conditions warrant. As required by Rule 13a-15(d), the Company’s management, including the Chief Executive Officer and the Chief Financial Officer, also conducted an evaluation of the Company’s internal control over financial reporting to determine whether any changes occurred during the quarter ended December 30, 2023 that have

materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting. Based on that evaluation, there has been no such change during the period covered by this report.
