Management Commentary

Gross margin expanded by 1,810 basis points to 72.8% of net sales in the three months ended August 2, 2026, compared to 54.7% of net sales in the three months ended August 3, 2025. We recorded a reduction to cost of goods sold of $16.0 million related to refunds of previously incurred tariff charges. Excluding the impact of tariff refunds, gross margin was 59.6% in the three months ended August 2, 2026, an expansion of 490 basis points compared to the prior year. This increase in gross margin rate was primarily driven by an increase in average unit retail prices from reduced promotional activity, coupled with an improvement in product costs from our direct to factory sourcing initiative.

Selling, general and administrative expenses increased $0.7 million, or 1.1%, to $69.5 million in the three months ended August 2, 2026 compared to $68.8 million in the three months ended August 3, 2025. Selling, general and administrative expenses as a percentage of net sales increased by 510 basis points to 57.3% in the three months ended August 2, 2026, compared to 52.2% in the three months ended August 3, 2025. The increase in selling, general and administrative expenses as a percentage of net sales was mainly driven by an increase in advertising and shipping expenses, which was partially offset by leverage in variable expenses in our fulfillment centers and stores coupled with lower overhead expenses.

Balance Sheet and Liquidity

The Company ended the quarter with $26.8 million of cash and cash equivalents, $85.7 million of net working capital, and zero outstanding debt on the $70.0 million Asset Based Lending facility resulting in approximately $96 million of net liquidity.

Fiscal 2026 Outlook

Non-GAAP Measurements

Management believes that non-GAAP financial measures may be useful in certain instances to provide additional meaningful comparisons between current results and results in prior operating periods. Within this release, including the tables attached hereto, reference is made to adjusted earnings before interest, taxes, depreciation and amortization (EBITDA), Adjusted Net Income (Loss), Adjusted EPS, and Forecasted Adjusted EBITDA. See attached table “Reconciliation of Net Income (Loss) to EBITDA and EBITDA to Adjusted EBITDA,” for a reconciliation of net income (loss) to EBITDA and EBITDA to Adjusted EBITDA and “Reconciliation of

Net Income (Loss) to Adjusted Net Income (Loss) and EPS to Adjusted EPS” for a reconciliation of net income (loss) to adjusted net income (loss) and EPS to adjusted EPS for the three and six months ended August 2, 2026 and August 3, 2025. Also see attached table “Reconciliation of Forecasted Net Income (Loss) to Forecasted EBITDA and Forecasted EBITDA to Forecasted Adjusted EBITDA” for a reconciliation of forecasted Adjusted EBITDA for Fiscal 2026.

Adjusted EBITDA is a metric used by management and frequently used by the financial community, which provides insight into an organization’s operating trends and facilitates comparisons between peer companies, since interest, taxes, depreciation and amortization can differ greatly between organizations as a result of differing capital structures and tax strategies. Adjusted EBITDA excludes certain other items, which include significant non-cash items, and other charges or benefits resulting from transactions or events that are highly variable, significant in size, and that we do not believe are indicative of ongoing or future business operations.

Adjusted Net Income (Loss) and Adjusted EPS are metrics used by management and frequently used by the financial community, which provides insight into the effectiveness of our business strategies and to compare our performance against that of peer companies. Adjusted Net Income (Loss) and Adjusted EPS exclude restructuring expenses and impairment expenses that are not comparable from period to period.

The Company provides this information to investors to assist in comparisons of past, present and future operating results and to assist in highlighting the results of on-going operations. While the Company’s management believes that non-GAAP measurements are useful supplemental information, such adjusted results are not intended to replace the Company’s GAAP financial results and should be read in conjunction with those GAAP results.
