ITEM 9A. CONTROLS AND PROCEDURES Disclosure Controls and Procedures As required by Rule 13a-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), we carried out an evaluation under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this report. Based upon their evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, solely as a result of the material weakness identified by management and described below, our disclosure controls and procedures were not effective to ensure that material information relating to the Company required to be disclosed by the Company in reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms and to ensure 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. In designing and evaluating our disclosure controls and procedures, our management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurances of achieving the desired control objectives, and management necessarily was required to apply its judgment in designing and evaluating the controls and procedures. We continue to review our disclosure controls and procedures, and our internal control over financial reporting, and may from time to time make changes aimed at enhancing their effectiveness and to ensure that our systems evolve with our business. Changes in Internal Control over Financial Reporting Except for the material weakness identified by management and described below, there were no changes in our internal control over financial reporting during the quarter ended August 27, 2022 that have materially affected, or that are reasonably likely to materially affect, our internal control over financial reporting. Management’s Responsibility for Financial Statements Our management is responsible for the preparation, integrity and objectivity of our Consolidated Financial Statements and other financial information contained in our Annual Report on Form 10-K. Those Consolidated Financial Statements were prepared in conformity with accounting principles generally accepted in the United States. In preparing those Consolidated Financial Statements, management was required to make certain estimates and judgments, which are based upon currently available information and management’s view of current conditions and circumstances. The Audit Committee of our Board of Directors, which consists solely of independent directors, oversees our process of reporting financial information and the audit of our Consolidated Financial Statements. The Audit Committee stays informed of our financial condition and regularly reviews management’s financial policies and procedures, the independence of our independent auditors, our internal control over financial reporting and the objectivity of our financial reporting. Our independent registered public accounting firm has full access to the Audit Committee and meets with the Audit Committee periodically, both with and without management present. We have retained Ernst & Young LLP, an independent registered public accounting firm, to audit our Consolidated Financial Statements found in this Annual Report on Form 10-K for the year ended August 27, 2022. We have made available to Ernst & Young LLP all of our financial records and related data in connection with their audit of our Consolidated Financial Statements. 72 Management’s Report on Internal C ontrol Over Financial Reporting Our management is responsible for establishing and maintaining adequate internal control over financial reporting. 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 reporting purposes in accordance with accounting principles generally accepted in the United States. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Management has assessed the effectiveness of our internal control over financial reporting as of August 27, 2022. In making its assessment, management has utilized the criteria set forth by the Committee of Sponsoring Organizations (“COSO”) of the Treadway Commission in Internal Control—Integrated Framework (2013 Framework). Management concluded that based on its assessment, our internal controls over financial reporting were not effective as of August 27, 2022. Material Weakness 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. Our management identified a material weakness in internal control over financial reporting related to the revenue and accounts receivable process, primarily due to ineffective information technology general controls (ITGCs) in the area of user access over the CRM system that we are in the process of deploying. This issue was attributable to numerous role security defects that we experienced in the application and uncertainty that additional role security defects would not arise. Our business process controls within the revenue and accounts receivable process, both automated and manual, that are dependent on the completeness and accuracy of the information derived from the affected IT system were also deemed ineffective because they could have been adversely impacted. Our independent registered accounting firm, Ernst & Young LLP has issued an adverse audit report on the effectiveness of our internal control over financial reporting as of August 27, 2022, which is included in Item 8 of this Annual Report on Form 10-K. Following identification of the material weakness and prior to filing this Annual Report on Form 10-K, we completed substantive procedures for the year ended August 27, 2022 over our revenue and accounts receivable balances. Based on these procedures, management believes that our consolidated financial statements included in this Annual Report on Form 10-K have been prepared in accordance with U.S. GAAP. Our Chief Executive Officer and Chief Financial Officer have certified in certifications furnished with this Annual Report on Form 10-K that, to the best of their knowledge, the information contained in this Annual Report on Form 10-K fairly present, in all material respects, the financial condition and results of operations of the Company as of, and for, the periods presented in this Annual Report on Form 10-K. Ernst & Young LLP has issued an unqualified opinion on our financial statements, which is included in Item 8 of this Annual Report on Form 10-K. Remediation Management is currently working with the application provider to implement near-term and longer-term security enhancements to the CRM system that will provide improved control over user access. We believe that these actions as well as other enhancements to our business process controls, both automated and manual, will enable us to remediate the material weakness. The material weakness 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 currently believe that the remediation of the material weakness will be completed by the end of our fiscal 2023. 73 Report of Independent Regist ered Public Accounting Firm To the Shareholders and the Board of Directors of UniFirst Corporation Opinion on Internal Control over Financial Reporting We have audited UniFirst Corporation and subsidiaries’ internal control over financial reporting as of August 27, 2022, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 Framework) (the COSO criteria). In our opinion, because of the effect of the material weakness described below on the achievement of the objectives of the control criteria, UniFirst Corporation (and subsidiaries) (the Company) has not maintained effective internal control over financial reporting as of August 27, 2022, based on the COSO criteria. A material weakness is a deficiency, or 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 weakness has been identified and included in management’s assessment. Management has identified a material weakness in controls related to the Company’s revenue and accounts receivable process. The material weakness is the result of the aggregate effect of: (i) ineffective information technology (IT) controls over user access and security related to a new billing system that supports the revenue and accounts receivable process for a material volume of transactions and locations and (ii) design and operating deficiencies for certain transaction level controls within the revenue and accounts receivable process. As a result of the ineffective IT controls, process level automated controls and manual controls that are dependent on the completeness and accuracy of information derived from the affected IT system were concluded to be ineffective because they could have been adversely impacted. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of UniFirst Corporation as of August 27, 2022 and August 28, 2021, the related consolidated statements of income, comprehensive income, shareholders’ equity and cash flows for each of the three years in the period ended August 27, 2022, and the related notes and the financial statement schedule listed in the Index at Item 15(a) of the Company. This material weakness was considered in determining the nature, timing and extent of audit tests applied in our audit of the fiscal 2022 consolidated financial statements, and this report does not affect our report dated October 25, 2022, which expressed an unqualified opinion thereon. 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 included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and 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 74 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. /s/ Ernst & Young LLP Boston, Massachusetts October 26, 2022 75 ITEM 9B.
