Basis for Opinions

The Company’s management is responsible for these financial statements, 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 these financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (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 audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures to respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. 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 audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

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.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Inventory, Net – Excess and Slow-Moving Inventory Reserve – Refer to Note 2 to the financial statements

Critical Audit Matter Description

The Company establishes inventory reserves to record its inventory at the lower of cost or net realizable value. A portion of the inventory reserves represents an amount for excess and slow-moving inventory on hand that is expected to be written-off or otherwise disposed of below cost at a future date. The Company’s estimate of the appropriate amount of the excess and slow-moving inventory reserve utilizes certain inputs and involves judgment. Such inputs include data associated with historical trends, historical inventory write-off activity, and the on-hand inventory aging. The calculation and analysis of historical trend data, historical write-off activity, and the application of this analysis to on-hand inventory involves complex calculations.

We identified the estimated inventory reserve for excess and slow-moving inventory as a critical audit matter given the estimation uncertainty is impacted by a number of subjective factors including current and future customer merchandise preference, consumer spending trends and economic conditions. This required a high degree of auditor judgment and an increased extent of effort when performing audit procedures to evaluate the methodology and the reasonableness of these subjective factors in combination with assumptions and inputs including historical inventory trends, historical inventory write-off activity, and the on-hand inventory aging used to determine excess and slow-moving inventory.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the excess and slow-moving inventory reserve included the following, among others:

•We tested the effectiveness of controls over management’s excess and slow-moving inventory reserve estimate.

•We compared actual write-off activity in the current year to the excess and slow-moving inventory reserve estimated by the Company in the prior year to evaluate management’s ability to accurately estimate the excess and slow-moving inventory reserve.

•We evaluated the appropriateness of and performed audit procedures over specified inputs supporting management’s excess and slow-moving inventory reserve estimate, including the age of on-hand inventory, historical inventory trends, and historical write-off activity.

•We evaluated the appropriateness and consistency of management’s methods and assumptions used in developing their estimate of the excess and slow-moving inventory reserve, which included consideration of write-off trends by merchandise category, on-hand inventory aging distribution and the impact of current and future customer merchandise preference, consumer spending trends and economic conditions.

•We reperformed the calculation of the excess and slow-moving inventory reserve utilizing the inputs, assumptions, and methodology consistent with management’s estimate.

•We looked for indications that the reserve for excess and slow-moving inventory may be understated by evaluating write-off activity of inventory subsequent to August 2, 2025.
