Check the appropriate box below if the Form 8-K is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

On January 31, 2013, Destination Maternity Corporation (the “Company”) issued a press release and held a broadly accessible conference call to discuss its financial results for its first fiscal quarter ended December 31, 2012. A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated herein by reference.

The press release contained non-GAAP financial measures within the meaning of the Securities and Exchange Commission’s Regulation G, including: (a) Adjusted EBITDA (operating income before deduction for the following non-cash charges: (i) depreciation and amortization expense; (ii) loss on impairment of tangible and intangible assets; (iii) loss on disposal of assets; and (iv) stock-based compensation expense), together with the percentage of net sales represented by this measure; (b) Adjusted net income, before stock-based compensation expense and loss on extinguishment of debt; (c) Adjusted net income per share - diluted, before stock-based compensation expense; (d) Adjusted net income per share - diluted, before stock-based compensation expense and loss on extinguishment of debt; and (e) net cash.

The Company 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. The Company provides these measures to investors to assist them in performing their analysis of its historical operating results. Each of these non-GAAP financial measures, except net cash (debt), 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, 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. The Company may calculate each of these non-GAAP financial measures differently than other companies.

With respect to the non-GAAP financial measures discussed in the press release, the Company has provided, as an attachment to such press release, a reconciliation of the non-GAAP financial measures to the most directly comparable GAAP financial measures.

The disclosure in this Current Report, including in the Exhibits attached hereto, of any financial information shall not constitute an admission that such information is material.
