(a) EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES

The SEC defines the term “disclosure controls and procedures” to mean a company’s controls and other procedures that are designed to ensure that information required to be disclosed in the reports that it files or submits under the Exchange Act is recorded, processed, summarized, and reported, within the time periods specified in the SEC’s rules and forms. “Disclosure controls and procedures” include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Exchange Act of 1934, as amended, is accumulated and communicated to the issuer’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Our disclosure controls and procedures are designed to provide reasonable assurance that such information is accumulated and communicated to our management. Our management (with the participation of our Chief Executive Officer (CEO) and Chief Financial Officer (CFO)) has conducted an evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act). Based on such evaluation, our CEO and our CFO have concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of June 28, 2025.

(b) 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) and 15d-15(f) under the Exchange Act). Our management, including our CEO and CFO, conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in the Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on its evaluation under the framework in the Internal Control-Integrated Framework (2013), our management concluded that our internal control over financial reporting was effective as of June 28, 2025.

In accordance with guidance issued by the Securities and Exchange Commission, companies are permitted to exclude acquisitions from their final assessment of internal control over financial reporting for the first fiscal year in which the acquisition occurred. Our management’s evaluation of internal control over financial reporting excluded the internal control activities of Inertial Labs, Inc. (Inertial Labs), which we acquired on January 28, 2025, as discussed in “Note 5. Acquisitions” under Item 8 of this Annual Report on Form 10-K. We have included the financial results of Inertial Labs in the Consolidated Financial Statements from the date of acquisition. Total revenues of Inertial Labs subject to the Company’s internal control over financial reporting represented approximately 2.3% of our consolidated revenue for the fiscal year ended June 28, 2025. Total assets of Inertial Labs subject to the Company’s internal control over financial reporting represented approximately 2.1% of our consolidated total assets as of June 28, 2025. Inertial Lab’s goodwill and intangible assets were subject to our management’s evaluation of internal control over financial reporting.

Our management has concluded that, as of June 28, 2025, our internal control over financial reporting was effective at the reasonable assurance level based on these criteria.

The effectiveness of the Company’s internal control over financial reporting as of June 28, 2025 has been audited by our independent registered public accounting firm PricewaterhouseCoopers LLP, as stated in their report which appears in this Annual Report on Form 10-K under Item 8 “Financial Statements and Supplementary Information.”

(c) CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING

There were no changes in our internal control over financial reporting, as defined in Exchange Act Rule 13a-15(f), during the quarter ended June 28, 2025, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

(d) LIMITATIONS ON EFFECTIVENESS OF CONTROLS

Our management, including our CEO and CFO, does not expect that our disclosure controls and procedures or our internal control will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. 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, within our company have been detected. Accordingly, our disclosure controls and procedures and our internal control provide reasonable assurance of achieving their objectives.
