Grocery Outlet Holding Corp.

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of our management including our Principal Executive Officer and Principal Financial Officer, we evaluated the effectiveness of the design and operation of our disclosure controls and procedures as defined by Rule 13a-15(e) and 15d-15(e) under the Exchange Act as of the end of the period covered by this report. Our disclosure controls and procedures are designed to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act, is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, and that such information is accumulated and communicated to our management, including our Principal Executive Officer and our Principal Financial Officer, as appropriate, to allow timely decisions regarding required disclosures.

Based on that evaluation, our Principal Executive Officer and Principal Financial Officer have concluded our disclosure controls and procedures were effective at a reasonable assurance level as of January 3, 2026.

Remediation of Previously Identified Material Weakness

As disclosed in our 2024 10-K, the Company previously identified a material weakness in internal control over financial reporting related to deficiencies in the design and operating effectiveness of certain information technology general computer controls.

Management’s remediation efforts began during the fourth quarter of fiscal 2023, which included a redesign of controls, implementation of additional training for user access, program change management and IT operations controls, and hiring additional internal and external resources. As of January 3, 2026, management concluded through continued testing that these specific controls have operated effectively for a sufficient period of time, and the material weakness was remediated.

Management's Report on Internal Control Over Financial Reporting

The Company's management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined by Rule 13a-15(f) of the Exchange Act. The Company's management conducted an assessment of the Company's internal control over financial reporting based on the framework established by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control - Integrated Framework (2013). Based on this assessment, the Company's management has concluded that, as of January 3, 2026, the Company's internal control over financial reporting was effective.

The Company's internal control over financial reporting as of January 3, 2026 has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report which is set forth below.

Changes in Internal Control over Financial Reporting

During the fiscal quarter ended January 3, 2026, there was no change in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting, other than the remediation of previously identified material weakness.

Limitations on Effectiveness of Controls

In designing and evaluating the disclosure controls and procedures and internal control over financial reporting, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs.

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.
