Management Commentary

President and CEO Stephanie Pugliese stated, “I am proud of the team for delivering another quarter of improved profitability, continuing our discipline on promotional reset, managing expenses and inventory levels, and further streamlining operations. These efforts led to enhanced gross margin, lower costs, reduced inventory levels, and improved free cash flow.”

“Through rigorous preparation and the alignment across all functions of the business, we entered the fourth quarter poised to exceed our customers’ expectations. We are pleased with the holiday results to date and are encouraged by our continued improvement in gross margin, operational execution, and customer response.”

“As we continue with our turnaround efforts, we are committed to building on this momentum. Moving forward, we will focus on re-energizing and expanding our customer base and prioritizing our assortment on the core durable products that our customers love.”

Operating Results for the Third Quarter ended November 2, 2025

Net sales decreased $12.2 million, or 9.6%, to $114.9 million in the three months ended November 2, 2025 compared to $127.1 million in the three months ended October 27, 2024. Direct-to-consumer net sales decreased by 15.5% to $67.4 million due to lower traffic, partially offset by higher average order values. Retail store net sales increased by 0.4% to $47.4 million primarily driven by two new store openings and higher average order values.

Gross margin increased to 53.8% of net sales in the three months ended November 2, 2025, compared to 52.3% of net sales in the three months ended October 27, 2024 overcoming a $3.0M tariff impact. The increase in gross margin rate was primarily driven by an increase in average unit retail sales from reduced promotional activity coupled with an improvement in product costs from our direct to factory sourcing initiative.

Selling, general and administrative expenses decreased $11.6 million, or 14.1%, to $70.7 million in the three months ended November 2, 2025 compared to $82.3 million in the three months ended October 27, 2024. Selling, general and administrative expenses as a percentage of net sales decreased to 61.5% in the three months ended November 2, 2025, compared to 64.8% in the three months ended October 27, 2024. The decrease in selling, general and administrative expense as a percentage of net sales was mainly driven by lower marketing costs coupled with a reduction in personnel and depreciation expenses.

Balance Sheet and Liquidity

The Company ended the quarter with $8.2 million of cash and cash equivalents, $51.1 million of net working capital, $44.6 million of outstanding debt on the $125.0 million Asset Based Lending facility resulting in $88.6 million of net liquidity.

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 and adjusted earnings per share (“EPS”). 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 for the three and nine months ended November 2, 2025, versus the three and nine months ended October 27, 2024 and attached table “Reconciliation of Net Income (Loss) to Adjusted Net Income (Loss) and Adjusted Net Income (Loss) to Adjusted EPS,” for a reconciliation of net income (loss) to adjusted net income (loss) and adjusted net income (loss) to adjusted EPS for the three and nine months ended November 2, 2025 versus the three and nine months ended October 27, 2024.

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 items that are unusual in nature or not comparable from period to period.

Adjusted Net Income (Loss) and Adjusted EPS is a metric 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 excludes restructuring expenses, impairment expenses and an addition to our valuation allowance on our deferred tax asset 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.
