The Company reported first fiscal quarter earnings per diluted share (“EPS”) on a generally accepted accounting principles (“GAAP”) basis of $0.35, and EPS on a non-GAAP adjusted basis, excluding acquisition-related and ERP system implementation costs (“Adjusted”), of $0.38.  Diluted EPS on a GAAP basis and Adjusted basis are reconciled in the table below:

See “Reconciliation of Reported (GAAP) to Adjusted Statements of Operations Data” for Notes

“As the leading bedding specialty retailer in the country, we continued to achieve strong results in the first quarter, evidenced by our 31.5% revenue growth over the prior year, despite the challenging industry consumer traffic and average unit price trends that we previously referenced,” stated Steve Stagner, Mattress Firm’s president and chief executive officer.  “With the opening of 46 new stores during the first quarter, we are well on our way to reaching our goal of opening more than 100 new stores for the third consecutive year and growing our company-operated store base above 1,100 during 2013. We are pleased with the ongoing sales and operating margin growth in the acquired Mattress Giant stores and that comparable-store sales growth turned positive in May now that those stores are included in our comparable-store sales results.  As we look ahead, we are excited by the new and innovative products now on our floors supported with national advertising and anticipate consistent sales and profitability growth over the remainder of 2013.”

The forward-looking statements contained in this press release, such as those relating to our net sales, GAAP and Adjusted EPS and net store unit change for fiscal year 2013, are subject to various risks and uncertainties, including but not limited to downturns in the economy; reduction in discretionary spending by consumers; our ability to execute our key business strategies and advance our market-level profitability; our ability to profitably open and operate new stores and capture additional market share; our relationship with our primary mattress suppliers; our dependence on a few key employees; the possible impairment of our goodwill or other acquired intangible assets; the effect of our planned growth and the integration of our acquisitions on our business infrastructure; the impact of seasonality on our financial results and comparable-store sales; our ability to raise adequate capital to support our expansion strategy; our success in pursuing and

completing strategic acquisitions; the effectiveness and efficiency of our advertising expenditures; our success in keeping warranty claims and comfort exchange return rates within acceptable levels; our ability to deliver our products in a timely manner; our status as a holding company with no business operations; our ability to anticipate consumer trends; risks related to our controlling stockholder, J.W. Childs Associates, L.P.; heightened competition; changes in applicable regulations; risks related to our franchises, including our lack of control over their operation and our liabilities if they default on note or lease obligations; risks related to our stock and other factors set forth under “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended January 29, 2013 filed with the Securities and Exchange Commission (“SEC”) on April 1, 2013 and our other SEC filings.  Forward-looking statements relate to future events or our future financial performance and reflect management’s expectations or beliefs concerning future events as of the date of this press release.  Actual results of operations may differ materially from those set forth in any forward-looking statements, and the inclusion of a projection or forward-looking statement in this press release should not be regarded as a representation by us that our plans or objectives will be achieved. We do not undertake to publicly update or revise any of these forward-looking statements, whether as a result of new information, future events or otherwise.

Non-GAAP Financial Measures

Adjusted EBITDA is defined as net income before income tax expense, interest income, interest expense, depreciation and amortization (“EBITDA”), without giving effect to non-cash goodwill and intangible asset impairment charges, gains or losses on store closings and impairment of store assets, gains or losses related to the early extinguishment of debt, financial sponsor fees and expenses, non-cash charges related to stock based awards and other items that are excluded by management in reviewing the results of operations. We have presented Adjusted EBITDA because we believe that the exclusion of these items is appropriate to provide additional information to investors about our ongoing operating performance excluding certain non-cash and other items and to provide additional information with respect to our ability to comply with various covenants in documents governing our indebtedness and as a means to evaluate our period-to-period results. In evaluating Adjusted EBITDA, you should be aware that in the future we may incur expenses that are the same as or similar to some of the adjustments in this presentation. Our presentation of Adjusted EBITDA should not be construed to imply that our future results will be unaffected by any such adjustments. We have provided this information to analysts, investors and other third parties to enable them to perform more meaningful comparisons of past, present and future operating results and as a means to evaluate the results of our ongoing operations. Management also uses Adjusted EBITDA to determine executive incentive compensation payment levels. In addition, our compliance with certain covenants under the credit agreement between our indirect wholly owned subsidiary, Mattress Holding Corp., certain lenders, and UBS Securities LLC, as sole arranger, bookrunner, and a lender, are calculated based on similar measures and differ from Adjusted EBITDA primarily by the inclusion of pro forma results for acquired businesses in those similar measures. Other companies in our industry may calculate Adjusted EBITDA differently than we do. Adjusted EBITDA is not a measure of performance under U.S. GAAP and should not be considered as a substitute for net income prepared in accordance with U.S. GAAP. Adjusted EBITDA has significant limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results as reported under U.S. GAAP.

The following table contains a reconciliation of our net income determined in accordance with U.S. GAAP to EBITDA and Adjusted EBITDA for the periods indicated (in thousands):

(a)                                 We receive cash payments from certain vendors for each new incremental store that we open (“new store funds”). New store funds are initially recorded in other noncurrent liabilities when received and are then amortized as a reduction of cost of sales over 36 months in our financial statements. Historically, we have considered new store funds as a component of Adjusted EBITDA when received since new store funds are included in cash provided from operations. The adjustment includes the amount of new store funds received during the period presented and eliminates the non-cash reduction in cost of sales included in our results of operations.

(b)                                 Reflects both non-cash effects included in net income related to acquisition accounting adjustments made to inventories and other acquisition-related cash costs included in net income, such as direct acquisition costs and costs related to integration of acquired businesses.

(c)                                  Consists of various items that management excludes in reviewing the results of operations, including $0.7 million of ERP system implementation costs incurred during the thirteen weeks ended April 30, 2013.

Adjusted EPS and the other “Adjusted” data provided in this press release are also considered non-GAAP financial measures.  We report our financial results in accordance with GAAP; however, management believes evaluating our ongoing operating results may be enhanced if investors have additional non-GAAP basis financial measures to facilitate year-over-year comparisons. Management reviews non-GAAP financial measures to assess ongoing operations and considers them to be effective indicators, for both management and investors, of our financial performance over time. Our management does not advocate that investors consider such non-GAAP financial measures in isolation from, or as a substitute for, financial information prepared in accordance with GAAP.  For more information, please refer to “Reconciliation of Reported (GAAP) to Adjusted Statements of Operations Data” below.

(1) On May 2, 2012, we acquired all of the equity interests of MGHC Holding Corporation (“Mattress Giant”), including 181 specialty retail stores.

On December 11, 2012, we acquired the assets and operations of Factory Mattress & Water Bed Outlet of Charlotte, Inc. (“Mattress Source”), including 27 mattress specialty retail stores. Acquisition-related costs, consisting of direct transaction costs and integration costs, are included in the results of operations as incurred. During the thirteen weeks ended May 1, 2012 and April 30, 2013, we incurred approximately $1.2 million and $0.3 million of acquisition-related costs, respectively.

(2) Reflects implementation costs included in the results of operations as incurred, consisting primarily of training-related costs,  related to the roll-out of the Microsoft Dynamics AX for Retail Enterprise Resource Planning system (“ERP system”). During the thirteen weeks ended April 30, 2013, we incurred approximately $1.0 million of ERP system implementation costs.

Our “As Adjusted” data is considered a non-U.S. GAAP financial measure and is not in accordance with, or preferable to, “As Reported,” or GAAP financial data. However, we are providing this information as we believe it facilitates year-over-year comparisons for investors and financial analysts.
