Destination XL Group, Inc. Reports Third Quarter Financial Results

Sales of $101.9 million, Net Loss of $(0.08) per diluted share

Separately Announces Definitive Agreement to Combine with FullBeauty in a Merger of Equals

CANTON, Mass., December 11, 2025 – Destination XL Group, Inc. (NASDAQ: DXLG), the leading integrated-commerce specialty retailer of Big + Tall men’s clothing and footwear, today reported operating results for the third quarter of fiscal 2025.

Third Quarter Financial Highlights

Management’s Comments

“Since the start of the fiscal year, we have pursued three critically important strategic initiatives to address ongoing volatility, evolving consumer dynamics, and challenges specific to the Big +Tall retail sector: assortment, our proprietary FiTMAP® technology, and promotions. We believe these strategic initiatives will better position the Company’s return to growth and enhance value for our shareholders,” said Harvey Kanter, President and CEO.

“Our sales results continue to reflect a big and tall customer who is not shopping as frequently or spending as much money with DXL as we have seen in prior years. There has been a discernable shift in customer preference towards entry level price points and private brands, which compels us to extend and evolve our core assortment to provide a greater selection of our private and value-driven brands. In addition, we are also accelerating the roll out of our FiTMAP scanning technology to additional stores, which allows us to build a deeper level of engagement with our customers. FiTMAP scanning uniquely positions DXL to more rapidly help consumers respond to GLP-1 medications which are transforming their lives. As weight loss journeys accelerate, customers’ needs are shifting - sizes are changing, confidence is growing, and shopping habits are evolving. DXL is embracing that journey using tools like FiTMAP.”

“Despite the dynamic consumer environment, we are confident in our regimented process, structure and discipline that sets us up for greater success when we return to growth. As noted, this discipline has been key in guiding our marketing and promotional strategies, enabling us to make dynamic, real-time adjustments to our assortment. Our operating regimen has maintained solid merchandise margins while proactively managing our inventory to a healthy position for the holiday season. We have been aggressively pivoting our sourcing strategy to diversify away from high tariff countries, negotiate better cost sharing with vendors, and value engineer product cost savings. We are also conducting a comprehensive review of our pricing across all private brands.”

“Our strategic priorities are supported through strong positions in cash, investments, debt, merchandise margins and inventory. We are ending the quarter with $27.0 million in cash and investments, no debt, merchandise margins that only decreased by 30 basis points from last year’s third quarter and an inventory position that is down 4.6% from last year's third quarter, and importantly, is down over 30% from 2019,” Mr. Kanter concluded.

Strategic Priorities:

Assortment

Over the course of the next two years, we are strategically shifting our assortment to prioritize private brands, which deliver consistent fit, the flexibility to balance trend-right fashion with core essentials and stronger margins. To support this focus, we are reducing investment in underperforming national brands, which will drive higher profitability and enable us to leverage strategic promotions to fuel customer acquisition and sales growth. Our intent is to grow private brand sales penetration from 57% at the start of fiscal 2025 to greater than 60% in 2026 and to greater than 65% in 2027. We are confident that with the strength of our assortment, enhanced storytelling, and strategic marketing efforts, we can drive greater customer loyalty and position our private brands as a primary reason customers choose DXL.

FiTMAP

Over the past three years, we have been working with and testing a proprietary FiTMAP® Sizing Technology for which we have an exclusive license for Big + Tall men until 2030. This innovative, contactless, digital scanning technology captures 243 unique measurements and offers custom clothing options and a great fit for all our customers. FiTMAP offers a unique experience for our customers, whether selecting from our Ready-to-Wear clothing or opting for custom garments. We are able to provide recommended sizes in all of our private brands, as well as 29 of our national brands. We believe this technology will enhance customer engagement, attract new customers and further establish DXL as a technology leader in men's big + tall apparel. To date, we have scanned over 30,000 customers. At the end of the third quarter of fiscal 2025, FiTMAP was in 88 DXL retail locations, and as of the end of September 2025, the technology is available on our mobile app, providing our customers with the ability to self-scan. We plan to expand to another 100 stores in the first half of fiscal 2026.

Promotional Strategy

We have continued to reframe our promotional strategy around a more disciplined, strategic framework that prioritizes relevance, competitiveness, and a stronger perception of value. Our customer has been telling us that we need to create greater levels of value, and our go-forward approach treats promotions like a managed category, with a clear and deliberate intent around timing, product focus, and purpose to drive sales, engagement, and brand equity. We continue to drive our positioning to maximize the return on every markdown dollar, better align with strategic imperatives, and precisely target specific customer cohorts.

Third Quarter Results

Sales

Total sales for the third quarter of fiscal 2025 were $101.9 million, as compared to $107.5 million for the third quarter of fiscal 2024. The decrease in total sales was primarily attributable to a decrease in comparable sales for the third quarter of 7.4%, partially offset by an increase in non-comparable sales from new stores. Comparable sales were down 6.7% in August, down 9.3% in September, and down 5.8% in October, which was a slight improvement from the first half of fiscal 2025.

The third quarter comparable sales decrease of 7.4% consisted of a comparable sales decrease of 5.2% from stores and a comparable sales decrease of 13.1% from our direct business. The decrease in traffic continued to be the primary driver for the decrease in comparable sales. While conversion rate was up slightly, our dollars per transaction were down, partly due to the shift in product mix toward more value-driven merchandise, as our customers continue to be price sensitive due to reduced discretionary spending.

While we have seen positive results from our loyalty program, Price Match Guarantee, FiTMAP, and our Heroes discounts, our total active customer file has continued to be under pressure as customers are spending less and shopping less frequently in the current environment.

Comparable sales through the first five weeks of the fourth quarter of fiscal 2025 were down 5.7%, which is an improvement in trend over the third quarter of fiscal 2025.

Gross Margin

For the third quarter of fiscal 2025, our gross margin rate, inclusive of occupancy costs, was 42.7% as compared to a gross margin rate of 45.1% for the third quarter of fiscal 2024.

Our gross margin rate decreased by 240 basis points, which was driven by an increase of 210 basis points in occupancy costs, as a percentage of sales, due to the deleveraging from lower sales and increased rents from new stores and lease extensions. Merchandise margin for the third quarter decreased by 30 basis points, as compared to the third quarter of fiscal 2024, primarily due to the impact of tariffs and increased markdown activity and promotional offers associated with our marketing initiatives. These increased costs were partially offset by an improvement in merchandise margins as a result of a shift in product mix toward our private brand merchandise.

There remains significant volatility with respect to evolving trade policies and the enactment of additional tariffs globally. Through vendor negotiations, sourcing diversification and cost mitigation programs, we have and will continue to take proactive measures to mitigate the impact of tariffs and trade restrictions on our business and our customers. Given the volatility that currently exists around these trade discussions, it is difficult to determine the potential impact that these tariffs may have on our financial results. However, if currently enacted rates remain in effect throughout the remainder of the fiscal year, and no new tariffs are added, we estimate that the impact of tariffs on gross margin for fiscal 2025 will be approximately $2.0 million. For the third quarter and first nine months of fiscal 2025, the impact of tariffs on merchandise margins was estimated to be approximately 60 basis points and 25 basis points as a percentage of sales, respectively.

Selling, General & Administrative

As a percentage of sales, SG&A (selling, general and administrative) expenses for the third quarter of fiscal 2025 were 44.7% as compared to 44.1% for the third quarter of fiscal 2024.

On a dollar basis, SG&A expenses decreased by $1.9 million as compared to the third quarter of fiscal 2024. The decrease was primarily due to a decrease in supporting payroll costs and incentive-based compensation.

Marketing costs were 6.0% of sales for the third quarter of fiscal 2025 as compared to 5.7% of sales for the third quarter of fiscal 2024. For fiscal 2025, marketing costs are expected to be approximately 6.0% of sales.

Management views SG&A expenses through two primary cost centers: Customer Facing Costs and Corporate Support Costs. Customer Facing Costs, which include store payroll, marketing and other store and direct operating costs, represented 25.2% of sales in the third quarter of fiscal 2025 as compared to 24.2% of sales in the third quarter of fiscal 2024. Corporate Support Costs, which include the distribution center and corporate overhead costs, represented 19.5% of sales in the third quarter of fiscal 2025 as compared to 19.9% of sales in the third quarter of fiscal 2024.

Interest Income, Net

Net interest income for the third quarter of fiscal 2025 was $0.1 million as compared to $0.6 million for the third quarter of fiscal 2024. For both periods, interest income was earned from investments in U.S. government-backed investments and money market accounts. The decrease in interest income was primarily due to the decrease in the average balance of investments during the first nine months of fiscal 2025 as compared to the prior year period. Interest costs for both periods were minimal because we had no outstanding debt and no borrowings under our credit facility.

Income Taxes

Our income tax provision for interim periods is determined using an estimate of our annual effective tax rate, adjusted for discrete items, if any. Each quarter, we update our estimate of the annual effective tax rate and make a year-to-date adjustment to the provision.

For the third quarter of fiscal 2025, the Company's effective tax rate was 26.1% as compared to an effective tax rate of 9.2% for the third quarter of fiscal 2024. The effective tax rate for the first nine months of fiscal 2025 reflects an annual effective tax rate estimate of 18.3%, net of discrete items and the impact of permanent book-to-tax differences as well as the impact of adjustments to our net operating losses reflected in our recently filed tax returns.

Net Loss

For the third quarter of fiscal 2025, net loss was $4.1 million, or $(0.08) per diluted share, as compared to a net loss for the third quarter of fiscal 2024 of $1.8 million, or $(0.03) per diluted share. The decrease in earnings for the third quarter of fiscal 2025 was driven primarily by the decrease in sales.

Adjusted EBITDA

Adjusted EBITDA, a non-GAAP measure, for the third quarter of fiscal 2025 was $(2.0) million, as compared to $1.0 million for the third quarter of fiscal 2024.

Cash Flow

Cash flow from operations for the first nine months of fiscal 2025 was $(3.2) million as compared to $12.5 million for the first nine months of fiscal 2024. The decrease in cash flow from operations was primarily due to a decrease in earnings as well as the timing of other working capital.

Free cash flow, before capital expenditures for store development, a non-GAAP measure, was $(10.9) million for the first nine months of fiscal 2025 as compared to $2.5 million for the first nine months of fiscal 2024.

Free cash flow, a non-GAAP measure, was $(20.2) million for the first nine months of fiscal 2025 as compared to $(7.0) million for the first nine months of fiscal 2024.

Non-GAAP Measures

Adjusted EBITDA, adjusted EBITDA margin, free cash flow before capital expenditures for store development and free cash flow are non-GAAP financial measures. Please see “Non-GAAP Measures” below and reconciliations of these non-GAAP measures to the comparable GAAP measures that follow in the tables below.

Balance Sheet & Liquidity

As of November 1, 2025, we had cash and investments of $27.0 million as compared to $43.0 million as of November 2, 2024, with no outstanding debt in either period. The decrease in cash and investments at November 1, 2025 as compared to November 2, 2024 included $13.1 million on capital spent over the past 12 months for new store development and $3.3 million of shares repurchased during the fourth quarter of fiscal 2024. We did not have any borrowings under our credit facility during either period and, as of November 1, 2025, the availability under our credit facility was $73.6 million, as compared to $78.1 million as of November 2, 2024. Availability under our credit facility is primarily driven by our available inventory.

During the third quarter of fiscal 2025, we amended our credit facility to extend the maturity of the facility from October 28, 2026 to August 13, 2030. In connection with the amendment, we also reduced the size of the credit facility from $125.0 million to $100.0 million to more closely align the credit facility with the Company's lower inventory levels. The Company's availability under the credit facility did not materially change as a result of the amendment.

As of November 1, 2025, our inventory decreased $4.1 million to $85.0 million, as compared to $89.1 million as of November 2, 2024. We continue to take proactive measures to manage our inventory and adjust our receipt plan given the ongoing macroeconomic factors affecting consumer spending, while at the same time, accelerating certain receipts to minimize the impact of tariffs. At November 1, 2025, our clearance inventory was 10.0% of our total inventory, as compared to 9.2% at November 2, 2024. Our inventory position is healthy, and our clearance levels are in line with our benchmark of 10%. Our inventory turnover rate has improved by over 30% from fiscal 2019.

Retail Store Information

The following is a summary of our retail square footage since the end of fiscal 2022 through the end of the third quarter of fiscal 2025:

During the first nine months of fiscal 2025, we opened eight new DXL stores, converted two Casual Male XL retail stores and one Casual Male XL outlet to DXL retail stores and two Casual Male XL outlets to DXL outlets. We expect our capital expenditures for fiscal 2025 to range from $17.0 million to $19.0 million, net of tenant incentives.

Digital Commerce Information

We distribute our national brands and private brand merchandise directly to consumers through our stores, website, app, and third-party marketplaces. Digital commerce sales, which we also refer to as direct sales, are defined as sales that originate online, whether through our website, at the store level or through a third-party marketplace. Our direct business is a critical component of our business and an area of significant growth opportunity for us. For the third quarter of fiscal 2025, our direct sales were $27.3 million, or 26.8% of sales, as compared to $31.3 million, or 29.1% of sales, in the third quarter of fiscal 2024. The decrease in direct sales was driven primarily by a decrease in online traffic.

Non-GAAP Measures

In addition to financial measures prepared in accordance with U.S. generally accepted accounting principles (“GAAP”), this press release contains non-GAAP financial measures, including adjusted EBITDA, adjusted EBITDA margin, free cash flow before capital expenditures for store development, and free cash flow. The presentation of these non-GAAP measures is not in accordance with GAAP and should not be considered superior to or as a substitute for net income (loss), net income (loss) per diluted share or cash flows from operating activities or any other measure of performance derived in accordance with GAAP. In addition, not all companies calculate non-GAAP financial measures in the same manner and, accordingly, the non-GAAP measures presented in this release may not be comparable to similar measures used by other companies. The Company believes the inclusion of these non-GAAP measures help investors gain a better understanding of the Company’s performance, especially when comparing such results to previous periods, and that they are useful as an additional means for investors to evaluate the Company's operating results when reviewed in conjunction with the Company's GAAP financial statements. Reconciliations of these non-GAAP measures to their comparable GAAP measures are provided in the tables below.

Adjusted EBITDA is calculated as earnings before interest, taxes, depreciation and amortization and adjusted for asset impairment charges (gain) and accrual for estimated non-recurring legal settlement costs, if any. Adjusted EBITDA margin is calculated as adjusted EBITDA divided by total sales. The Company believes that providing adjusted EBITDA and adjusted EBITDA margin is useful to investors to evaluate the Company’s performance and are key metrics to measure profitability and economic productivity.

Free cash flow is a metric that management uses to monitor liquidity. Management believes this metric is important to investors because it demonstrates the Company’s ability to strengthen liquidity while supporting its capital projects and new store development. Free cash flow is calculated as cash flow from operating activities, less capital expenditures and excludes the mandatory and discretionary repayment of debt. Free cash flow before capital expenditures for store development is calculated as cash flow from operating activities less capital expenditures other than capital expenditures for store development. Capital expenditures for store development includes capital expenditures for new stores, conversions of Casual Male XL stores to DXL and remodels. Capital expenditures related to store relocations and maintenance are not included in store development.
