DESTINATION MATERNITY REPORTS

FIRST QUARTER FISCAL 2015 FINANCIAL RESULTS

Moorestown, NJ, June 11, 2015 – Destination Maternity Corporation (NASDAQ: DEST), the world’s leading maternity apparel retailer, today announced results for the first quarter ended May 2, 2015. On May 28, 2015 the Company announced that its Board of Directors declared a regular quarterly cash dividend of $0.20 per share payable July 23, 2015.

For the first quarter of fiscal 2015, the Company reported income of $0.19 per diluted share on a GAAP basis, or $0.27 per diluted share, excluding other charges associated with relocation of the Company’s headquarters and distribution operations, and management and organizational changes. This compares to adjusted earnings per diluted share (non-GAAP) of $0.59 for the comparable three month period ended May 3, 2014. For a reconciliation of GAAP to non-GAAP financial information, refer to the financial tables at the end of this press release.

Anthony M. Romano, Chief Executive Officer of Destination Maternity Corporation, said, “While our adjusted EBITDA before other charges of $12.0 million was less than the prior year’s $18.1 million, our performance was about where we expected given this point in our turnaround. Our reported comparable sales for the quarter were down 1.1% versus the prior year’s down 4.0%, driven entirely by a slow February, which was significantly impacted by weather. The Easter sales shift performed in line with typical before and after sales builds and generated a slightly positive comp for the combined months of March and April versus a negative 3.6% comp in the prior year.

“Our gross margin declined year-over-year by approximately 400 basis points, driven by continued aggressive promotions to liquidate excess prior season inventory, including our adoption of a more typical markdown cadence and in-season clearance process. The promotional activity impacted most of the quarter as the excess prior season inventory was not removed from our stores and leased partners until after Easter. After the removal of the excess inventory, we have seen early signs of improvement, including stores with less inventory that are easier to shop, marketing messages that are visually more appealing, and higher average unit retail selling prices and increased conversion rates. We are also encouraged by the ongoing momentum and improving sales comp trend in several key classes at both Motherhood and A Pea in the Pod.

“We are keenly focused on appropriate inventory levels to generate modest comp sales with faster turns. However, inventory purchases for spring and summer were made under the old

methodology and thus have excess units in the pipeline relative to the needs of the current sales plan. This will continue to pressure margins in the second and third quarters, as we transition seasons and timely exit seasonal product to achieve healthy inventory levels. We have been aggressively changing our processes, refining our technology tool set and adding key talent to address the inventory productivity opportunities. We are in the final stages of the selection process for a new best-in-class allocation tool, which we anticipate will be live in early Fiscal 2016.

“We have also been busy developing a comprehensive real estate portfolio strategy, re-evaluating and re-engaging each of our third party strategic partners, and finalizing the relocation of our distribution center from Philadelphia to Florence, NJ.

“In summary, it has been a productive quarter. Our culture change is in full swing. Customer focused decisions are being made more consistently. We have ingrained inventory discipline into the culture with clear strategies and life cycle for each SKU. We have assembled a strong and diverse leadership team and have highly engaged and aligned corporate and store team members, all critical components of a strong foundation to support future success.”

First Quarter Fiscal 2015 Financial Results

Net sales for the first quarter of fiscal 2015 were $141.6 million compared with $143.5 million for the comparable three month period ended May 3, 2014. The slight decrease in total reported sales resulted primarily from decreased sales related to the Company’s continued efforts to close underperforming stores and a decrease in comparable sales, substantially offset by increased international sales. The primary driver of the comparable sales decrease was adverse weather conditions across much of the United States during February, which suppressed store traffic and adversely impacted sales, particularly sales of Spring merchandise, which represent a significantly larger percentage of the Company’s total sales for the first fiscal quarter than do sales of Fall merchandise.

Comparable sales for the first quarter of fiscal 2015 decreased 1.1%, compared to a 4.0% decrease for the three months ended May 3, 2014.

Gross margin for the first quarter of fiscal 2015 decreased to 50.4% from 54.4% for the three months ended May 3, 2014. The year-over-year decrease in gross margin is consistent with the Company’s previous estimates and reflects price promotional and markdown activity to spur sales and more aggressively manage inventory, including the Company’s continued efforts to dispose of out-of-season merchandise.

Selling, general and administrative expenses (“SG&A”) for the first quarter of fiscal 2015 decreased 0.7% to $64.0 million from $64.5 million for the three months ended May 3, 2014. As a percentage of net sales, SG&A increased to 45.2% for the first quarter of fiscal 2015 compared to 45.0% for the three months ended May 3, 2014. The slight decrease in expense reflects a non-recurring reduction of $1.2 million from settlement of certain unclaimed property matters, cost reductions resulting from the Company’s continued closure of underperforming stores, and lower marketing and advertising expense, substantially offset by higher expenses for self-insured employee healthcare benefits and variable incentive compensation (based on pro-rata financial projections).

Store closing, asset impairment and asset disposal expenses for the first quarter of fiscal 2015 increased to $1.0 million from $0.3 million for the three months ended May 3, 2014 primarily due to increased store asset impairments.

Adjusted EBITDA was $10.4 million for the first quarter of fiscal 2015, compared to $17.8 million for the three months ended May 3, 2014. Adjusted EBITDA before other charges was $12.0 million for the first quarter of fiscal 2015, compared to $18.1 million for the three months ended May 3, 2014. Adjusted EBITDA is defined in the financial tables at the end of this press release.

Net income for the first quarter of fiscal 2015 was $2.5 million, compared to net income of $7.7 million for the three months ended May 3, 2014. Adjusted net income for the first quarter of fiscal 2015, which is presented in the financial tables at the end of this press release, was $3.7 million, and excludes total other charges of $1.1 million, net of tax, comprised of $0.6 million, net of tax, or $0.05 per diluted share, related to the Company’s relocations of its headquarters and distribution operations and $0.5 million, net of tax, or $0.04 per diluted share, related to management and organizational changes. Adjusted net income for the three months ended May 3, 2014 was $8.0 million, and excludes total other charges of $0.3 million, net of tax, or $0.02 per diluted share, related to the Company’s relocations of its headquarters and distribution operations.

Credit Facility

In accordance with the terms of its Credit Facility, effective June 3, 2015 the Company’s permitted borrowings under Tranche A of the Credit Facility were increased by $15 million at the Company’s request to provide additional financial flexibility. After the increase, total permitted borrowings under the Credit Facility are $76 million, subject to the Company’s Borrowing Base formula.

Guidance for Fiscal 2015

Financial guidance for the full year fiscal 2015 is as follows:

Relocations of Corporate Headquarters and Distribution Operations

The relocations of the Company’s corporate headquarters and distribution operations from Philadelphia, Pennsylvania to southern New Jersey continue to progress on schedule. In January 2015 the Company completed the relocation of its corporate headquarters into more modern, spacious, bright and open offices in Moorestown, New Jersey. Material handling equipment is currently being installed and tested at the Company’s now completed, state-of-the-art distribution facility in Florence, New Jersey. Relocation of the Company’s distribution operations is expected to be completed in mid-calendar 2015.

The Company projects additional charges of approximately $0.8 million pretax, or approximately $0.5 million after tax ($0.04 per diluted share) through completion of the relocations in mid-calendar 2015. The Company projects that, once it is fully operating in both its new headquarters and new distribution center facilities, its ongoing annualized after-tax earnings benefit from the relocations will be approximately $0.10 per diluted share, and its ongoing annualized after-tax cash benefit from the relocations will be approximately $4 million.

The Company had capital expenditures associated with these relocations of approximately $7 million in the first quarter of fiscal 2015 ($36 million cumulatively through May 2, 2015), and projects additional capital expenditures of approximately $2 million through completion of the relocations, with nearly $4 million of this amount offset by construction allowance contributions from the landlord for its new headquarters building. The Company previously received $15 million from capital equipment financing provided by the Company’s Credit Facility bank to partially finance the material handling equipment in the Florence facility.

Reconciliation of Non-GAAP Financial Measures

This press release and the accompanying financial tables contain non-GAAP financial measures within the meaning of the SEC’s Regulation G, including 1) Adjusted net income, 2) Adjusted net income per share (diluted), 3) Adjusted EBITDA, 4) Adjusted EBITDA before other charges, 5) Adjusted EBITDA margin, 6) Adjusted EBITDA margin before other charges, and 7) Net (debt) cash. In the accompanying financial tables, we have provided reconciliations of these non-GAAP financial measures to the most directly comparable GAAP financial measures. Our management believes that each of these non-GAAP financial measures provides useful information about the Company’s results of operations and/or financial position to both investors and management. Each non-GAAP financial measure is provided because management believes it is an important measure of financial performance used in the retail industry to measure operating results, to determine the value of companies within the industry and to define standards for borrowing from institutional lenders. We use each of these non-GAAP financial measures as a measure of the performance of the Company. We provide these measures to investors to assist them in performing their analysis of our historical operating results. Each of these non-GAAP financial measures, except net (debt) cash, reflects a measure of the Company’s operating results before consideration of certain charges and consequently, none of these measures should be construed as an alternative to net income or operating income as an indicator of the Company’s operating performance, or as an alternative to cash flows from operating activities as a measure of the Company’s liquidity, as determined in accordance with generally accepted accounting principles. We may calculate each of these non-GAAP financial measures differently than other companies.
