Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information that is required to be disclosed in our Exchange Act reports is recorded, processed, summarized, and reported within the time periods that are specified in the SEC’s rules and forms and that such information is accumulated and communicated to management, including our Chief Executive Officer (Principal Executive Officer) and Chief Financial Officer (Principal Financial Officer), as appropriate, to allow timely decisions regarding any required disclosure. In designing and evaluating these disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives.

As of the end of the period covered by this report, our Chief Executive Officer and Chief Financial Officer evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act). Based on this evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as a result of material weaknesses in internal control over financial reporting as described below, the disclosure controls and procedures were not effective as of December 30, 2023.

Nevertheless, based on the performance of additional procedures by management designed to ensure reliability of financial reporting, our Chief Executive Officer and Chief Financial Officer have concluded that, notwithstanding the material weaknesses described below, the consolidated financial statements, included in this Form 10-K, fairly present, in all material respects, the Company’s financial position, results of operations, and cash flows as of the dates, and for the periods, presented in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP).

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). The Company’s internal control over financial reporting is a process designed by, or under the supervision of, the Company's Chief Executive Officer and Chief Financial Officer and effected by the Company's Board of Directors, management, and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the consolidated financial statements for external purposes in accordance with U.S. GAAP and includes those policies and procedures that:

•Pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company;

•Provide reasonable assurance that transactions are recorded as necessary to permit preparation of the consolidated financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and

•Provide reasonable assurance regarding the prevention or timely detection of any unauthorized acquisition, use, or disposition of the Company’s assets that could have a material effect on the consolidated financial statements.

Internal control over financial reporting has inherent limitations. Internal control over financial reporting is a process that involves human diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human failures. Internal control over financial reporting also can be circumvented by collusion or improper management override. Because of such limitations, there is a risk that material misstatements will not be prevented or detected on a timely basis by internal control over financial reporting. However, these inherent limitations are known features of the financial reporting process. Therefore, it is possible to design into the process safeguards to reduce, though not eliminate, this risk.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company's annual or interim consolidated financial statements will not be prevented or detected on a timely basis.

Our management, including our Chief Executive Officer and our Chief Financial Officer, under the oversight of our Board of Directors, assessed the effectiveness of our internal control over financial reporting as of December 30, 2023. In making this assessment, management used the criteria that have been set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework (2013). Based on its assessment, using those criteria, management concluded that, as of December 30, 2023, our internal control over financial reporting was not effective due to the following control deficiencies:

The Company did not have a sufficient complement of trained resources with specialized skills and knowledge in information technology general controls (ITGCs), or an alternative contingency plan, to timely respond to the impacts of turnover in key personnel with responsibility for ITGCs that occurred during 2023. As a result, the Company did not maintain effective ITGCs in the areas of user access, program change management, and computer operations over the information technology (IT) systems that support the Company’s financial reporting processes. Process-level automated controls that are dependent on the affected ITGCs and manual controls that rely on the integrity of data or reports from the affected systems across substantially all the Company’s processes were also deemed ineffective because they could have been adversely impacted.

The control deficiencies did not result in any identified misstatements to the consolidated financial statements, and there were no changes to previously released financial results. However, these control deficiencies create a reasonable possibility that a material misstatement to the consolidated financial statements will not be prevented or detected on a timely basis and, therefore, we concluded that the deficiencies represent material weaknesses in the Company's internal control over financial reporting.

Our independent registered public accounting firm, KPMG LLP, who audited the consolidated financial statements included in this Annual Report on Form 10-K issued an adverse opinion on the effectiveness of the Company’s internal control over financial reporting, which is included at the end of Part II, Item 9A of this form 10-K.

Remediation Efforts to Address Material Weaknesses

Management is implementing and will continue to implement measures designed to ensure that the control deficiencies contributing to the material weaknesses are remediated, such that the relevant controls are designed, implemented, and operating effectively. The remediation actions include:

•Enhancing our IT organization that is responsible for the development, monitoring, and testing of the ITGCs to ensure sufficiency of resources with the appropriate knowledge, experience, and training; and

•Developing a training program addressing ITGCs and related policies, to educate control owners on the principles and requirements of internal control activities, including maintaining adequate evidence of the controls’ operation and ensuring timely and consistent performance of the controls as designed.

We believe that these actions will remediate the material weaknesses, however, as we continue to evaluate and enhance our internal control over financial reporting, we may determine that additional measures to address the material weaknesses or adjustments to the remediation plan may be required. The material weaknesses will not be considered remediated until the applicable controls operate for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively. We expect that the remediation of these material weaknesses will be completed prior to the end of fiscal year 2024.

Changes in Internal Control over Financial Reporting

Other than with respect to identification of the material weaknesses described above, there were no changes in our internal control over financial reporting during the fiscal quarter ended December 30, 2023 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

USANA Health Sciences, Inc.:

Opinion on Internal Control Over Financial Reporting

We have audited USANA Health Sciences, Inc. and subsidiaries' (the Company) internal control over financial reporting as of December 30, 2023, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, because of the effect of the material weaknesses, described below, on the achievement of the objectives of the control criteria, the Company has not maintained effective internal control over financial reporting as of December 30, 2023, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 30, 2023 and December 31, 2022, the related consolidated statements of comprehensive income, stockholders’ equity, and cash flows for each of the years in the three-year period ended December 30, 2023, and the related notes and financial statement schedule II - valuation and qualifying accounts (collectively, the consolidated financial statements), and our report dated February 27, 2024 expressed an unqualified opinion on those consolidated financial statements.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial statements will not be prevented or detected on a timely basis. The following material weaknesses have been identified and included in management’s assessment: The Company did not have a sufficient complement of trained resources with specialized skills and knowledge in information technology general controls (ITGCs), or an alternative contingency plan, to timely respond to the impacts of turnover in key personnel with responsibility for ITGCs that occurred during 2023. As a result, the Company did not maintain effective ITGCs in the areas of user access, program change management, and computer operations over the information technology (IT) systems that support the Company’s financial reporting processes. Process-level automated controls that are dependent on the affected ITGCs and manual controls that rely on the integrity of data or reports from the affected systems across substantially all the Company’s processes were also deemed ineffective because they could have been adversely impacted. The material weaknesses were considered in determining the nature, timing, and extent of audit tests applied in our audit of the 2023 consolidated financial statements, and this report does not affect our report on those consolidated financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

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.
