“We continued to make progress in the second quarter executing against our strategic initiatives aimed at accelerating revenue growth, rationalizing expenses and improving profitability,” said Marla Ryan, Chief Executive Officer of Destination Maternity. “The hard work of our entire team drove an 18.4% year-over-year increase in ecommerce sales in the quarter, the 11^th consecutive quarter of online sales growth. Comparable sales also increased 1.2%, and our disciplined cost savings measures reduced SG&A costs by 5.1% year-over-year in the second quarter. On the ecommerce front, we are rolling out enhanced site capabilities and faster shipping solutions over the next 90 days to better serve the needs of the digital savvy, millennial mom. We have retained a leading marketing advisory firm to assist us in identifying ways to drive higher e-Commerce revenue growth, improve online conversion, and maximize our marketing spend. Our brick and mortar business is stabilizing as we are actively realigning our product offering and shifting inventory towards more evergreen styles to increase conversion and drive sales. We are confident the right steps are being taken to position the business for future success. With this momentum and our year to date results, we are reaffirming our full-year guidance of 30% to 45% growth in Adjusted EBITDA, before other charges. We expect Adjusted EBITDA, before other charges will more than double over last year’s second half.”

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 loss, 2) adjusted net loss per share - diluted, 3) Adjusted EBITDA, 4) Adjusted EBITDA before other charges, 5) Adjusted EBITDA margin, and 6) Adjusted EBITDA margin before other charges. In the accompanying financial tables, the Company has provided reconciliations of these non-GAAP financial measures to the most directly comparable GAAP financial measures. The Company’s 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. The Company uses each of these non-GAAP financial measures as a measure of the performance of the Company. In addition, certain of the Company’s cash and equity incentive compensation plans are based on the Company’s level of achievement of Adjusted EBITDA before other charges. The Company provides these various non-GAAP financial measures to investors to assist them in performing their analysis of its historical operating results. Each of these non-GAAP financial measures 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 (loss) or operating income (loss) as an indicator of the Company’s operating performance, as determined in accordance with generally accepted accounting principles. The Company may calculate each of these non-GAAP financial measures differently than other companies.

Although it is believed that the expectations reflected in such forward-looking statements are reasonable, no assurance can be given that such expectations will prove to have been correct and persons reading this announcement are therefore cautioned not to place undue reliance on these forward-looking statements which speak only as at the date of this announcement.
