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 weaknesses 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.

Management’s Responsibility for Financial Statements

17 unchanged sentences

As disclosed in Part II, Item 9A of our Annual Report on Form 10-K for fiscal 2024, we previously identified a material weakness related to deficiencies in our manage change and manage access processes that were not designed and operating effectively.

These deficiencies related to our CRM system and affected revenue and receivables as well as a group of legacy applications which affected revenue and receivables, supply inventory and merchandise in service.

While we worked during fiscal 2024 to remediate the previously identified material weakness, we were unable to fully remediate the material weakness prior to the end of fiscal 2024 and also identified deficiencies within the manage change and manage access processes related to additional applications.

The material weaknesses identified as of the end of fiscal 2024 include design and operating deficiencies in the manage change and manage access processes impacting all financially relevant business processes.

These deficiencies affected all financially relevant business processes.

While we worked during fiscal 2025 to remediate the previously identified material weakness, we were unable to fully remediate the material weakness prior to the end of fiscal 2025.

However, we made significant progress in remediating the design and operating effectiveness of our control environment and successfully addressed IT General Controls (ITGCs) for several key financial systems, including our legacy ERP platform and supporting tools and utilities.

At the end of fiscal 2025, the material weakness had been narrowed to deficiencies related to our CRM system which affected revenue and receivables as well as a group of legacy applications which affected revenue and receivables, supply inventory and merchandise in service.

Consequently, our automated and manual business process controls that rely upon information from the IT systems 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 30, 2025, which is included in Item 8 of this Annual Report on Form 10-K.

As a result of the identification of the material weaknesses, and prior to filing this Annual Report, along with our auditors, we performed further analysis and completed additional procedures intended to ensure our consolidated financial statements for the years ended August 31, 2024 and August 26, 2023 fairly present in all material respects the financial condition, results of operations and cash flows of the Company and have been prepared in accordance with generally accepted accounting principles.

Based on these procedures and analysis, and notwithstanding the material weaknesses in our internal control over financial reporting, our management has concluded that our consolidated financial statements and related notes thereto included in this Annual Report fairly present in all material respects the financial condition, results of operations and cash flows of the Company and have been prepared in accordance with generally accepted accounting principles.

As a result of the identification of the material weakness, and prior to filing this Annual Report, along with our auditors, we performed further analysis and completed additional procedures intended to ensure our consolidated financial statements for the years ended August 30, 2025 and August 31, 2024 fairly present in all material respects the financial condition, results of operations and cash flows of the Company and have been prepared in accordance with generally accepted accounting principles.

Based on these procedures and analysis, and notwithstanding the material weakness in our internal control over financial reporting, our management has concluded that our consolidated financial statements and related notes thereto included in this Annual Report fairly present in all material respects the financial condition, results of operations and cash flows of the Company and have been prepared in accordance with generally accepted accounting principles.

Our Chief Executive Officer and Chief Financial Officer have certified that, based on each such officer’s knowledge, the financial statements, as well as the other financial information included in this Annual Report, fairly present in all material respects the financial condition, results of operations and cash flows of the Company as of, and for, the periods presented in this Annual Report.

Ernst & Young LLP has issued an unqualified opinion on our financial statements, which is included in Part IV of this Annual Report on Form 10-K.

Our management is committed to maintaining a strong internal control environment.

In response to the material weaknesses described above, management is continuing to take actions to remediate the material weaknesses in internal control over financial reporting.

The intended remediation actions include:

(i) reassessing and redesigning our manage change and manage access processes and controls, (ii) enhancing oversight and involvement from our recently created business controls group, (iii) strengthening our internal policies related to ITGCs, (iv) enhancing training and awareness programs addressing ITGCs and policies, including further education of control owners regarding the principles and requirements of each control, (v) implementing an Identity and Access Management (IAM) system, which will provide enhanced control over the provisioning of user access

management, and (vi) onboarding our new CITO during the first quarter of fiscal 2025, who will oversee and inform the remediation actions.

We believe that these actions, when fully implemented, will remediate the material weaknesses, however, as we continue to evaluate and improve the applicable controls, management may determine that additional remediation measures are required.

The material weaknesses will not be considered remediated until applicable controls operate for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively.

Management is committed to successfully remediating the material weaknesses as promptly as possible.

Our management remains committed to maintaining a strong internal control environment.

In response to the material weakness, we implemented a number of remedial actions, including (i) redesigning our manage change and manage access processes and controls, (ii) invested additional resources to enhance oversight and involvement from our recently created Process, Risk and Controls group, (iii) strengthened our internal policies related to ITGCs, (iv) enhanced training and awareness programs addressing ITGCs and policies, including further education of control owners regarding the principles and requirements of each control, and (v) progressed our implementation of an Identity and Access Management (IAM) system, which will provide enhanced control over the provisioning of user access.

As a result of these efforts, we have made significant progress in remediating the design and operating effectiveness of our control environment and successfully addressed IT General Controls (ITGCs) for several key financial systems, including our legacy ERP platform and supporting tools and utilities.

We also advanced remediation efforts related to deficiencies in change management and access management for our CRM system and certain legacy applications, though some action items remained incomplete at the end of fiscal 2025.

Our focus remains on resolving the design and operational issues tied to change and access management in both the CRM and other legacy applications.

At the same time, we are investing in broader IT system improvements, including the implementation of Oracle Cloud ERP.

While unanticipated delays and complexities may extend the timeline, our plan at this time is to fully remediate the identified material weakness by the end of fiscal 2026.
