MATTRESS FIRM ANNOUNCES FIRST QUARTER FINANCIAL RESULTS

—  Net Sales Increased 38.1% With 16.1% Comparable-Store Sales Growth  —

—  Earnings per Diluted Share of $0.29 on a GAAP Basis, $0.31 on an Adjusted Basis  —

—  Raises Full Year Fiscal 2012 Guidance  —

HOUSTON, June 5, 2012 /BUSINESSWIRE/ — Mattress Firm Holding Corp. (NASDAQ: MFRM) today announced its financial results for the fiscal first quarter (13 weeks) ended May 1, 2012. Net sales for the first quarter increased 38.1% to $209.8 million, compared to $151.9 million in the first quarter of 2011, driven by comparable-store sales growth of 16.1% and an increase in store units from new store openings and acquisitions. The Company reported first-quarter GAAP earnings per diluted share (“EPS”) of $0.29. Excluding $1.2 million in acquisition-related costs attributable to the acquisition of Mattress Giant, which closed on May 2, 2012, first-quarter adjusted earnings per diluted share (“adjusted EPS”) were $0.31 compared with $0.05 in the first quarter of 2011.

On May 2, 2012, subsequent to the end of the fiscal first quarter, Mattress Firm completed the acquisition of the equity interests of Mattress Giant for approximately $44 million.  Mattress Giant is a specialty mattress retailer with approximately 180 stores in certain Texas and Florida markets where the Company also operates 240 Mattress Firm stores.  The acquisition is expected to advance the Company’s market-level profitability model that is centered on the benefits of increasing its “relative market share” in a given market.  The Company benefited from its accelerated efforts of an initial rebranding and transition of the acquired stores in advance of the Memorial Day holiday.  As a result, the vast majority of the acquired stores operated during the Memorial Day holiday (1) with Mattress Firm’s product offerings and its unique “Comfort by Color” merchandising approach, (2) utilizing Mattress Firm’s point of sale systems, (3) with initial training of substantially all of the former Mattress Giant sales associates, (4) with temporary signage in place where allowable and (5) with significant advertising investment and Mattress Firm’s brand presence.  After Labor Day, permanent signage as well as required renovations to bring the stores up to Mattress Firm’s standards will be undertaken and are expected to be substantially complete by the start of fiscal year 2013.

“Our first quarter results reflect our ability to execute on our profitable growth strategy through a combination of store unit growth and consistent increases in comparable-store sales,” stated Steve Stagner, Mattress Firm’s president and chief executive officer.  “We are extremely pleased with the successful execution of our plan to transition the newly acquired Mattress Giant stores in advance of the Memorial Day weekend, which is the beginning of our key summer selling season.  The  acquisition  has significantly strengthened our presence in several key markets.  We remain well positioned to capture additional market share and build long-term shareholder value as the largest U.S. specialty bedding retailer.”

First Quarter Financial Summary

·                  Net sales increased $57.9 million or 38.1% to $209.8 million in the first quarter of fiscal year 2012 from $151.9 million in the first quarter of fiscal year 2011.  The increase in net sales was the result of comparable-store sales growth of 16.1%, adding $24.0 million in net sales, and incremental net sales of $36.0 million from the opening of new stores and acquired stores prior to their inclusion in comparable-stores sales results, with such increases offset by a reduction in net sales of $2.1 million related to closed stores.

·                  The Company opened 30 new stores in the first quarter of fiscal year 2012, while closing four stores, bringing the total Company-operated stores to 755 as of May 1, 2012 (excluding the newly acquired Mattress Giant stores).

·                  Income from operations for the first quarter was $18.0 million.

This operating margin growth on an adjusted basis was driven primarily by a 250 basis-point improvement in gross profit margin and a 40 basis-point improvement in general and administrative expenses (excluding acquisition-related costs).

·                  Net income was $9.7 million in the first quarter of fiscal year 2012 and EPS was $0.29.  Excluding acquisition-related costs, net income was $10.5 million for the quarter and adjusted EPS was $0.31.

·                  Earnings before interest, taxes, depreciation and amortization and other adjustments (“Adjusted EBITDA”) increased 73.4% to $25.4 million in the first quarter of fiscal year 2012, compared to $14.7 million in the same period of fiscal year 2011.  Adjusted EBITDA as a percentage of sales improved 250 basis points to 12.1% from 9.6%.  See “Non-GAAP Financial Measures” below for a reconciliation of Adjusted EBITDA to net income.

Financial Guidance

The Company is raising EPS expectations for the fiscal year (52 weeks) ending January 29, 2013 (“fiscal year 2012”) to a range from $1.46 to $1.50, an increase from the previously communicated range from $1.40 to $1.48.  This outlook continues to assume fiscal 2012 sales in a range from $1.03 billion to $1.06 billion based on opening approximately 100 new stores and comparable-store sales growth of 10.0% to 12.0%.  Such net sales guidance for fiscal 2012 continues to include $90 million to $95 million of net sales from the Mattress Giant stores acquired on May 2, 2012.  Such EPS guidance for fiscal 2012 continues to include estimated nonrecurring direct transaction and integration costs (“acquisition-related costs”) of the Mattress Giant acquisition that are estimated to have a total per diluted share effect of $0.17 to $0.19, consisting of $0.09 to $0.11 in the second quarter, $0.04 to $0.05 in the third quarter and $0.02 in the fourth quarter.

For the fiscal second quarter ending July 31, 2012, the Company expects sales in a range from $270 million to $275 million, and EPS in a range from $0.26 to $0.29, inclusive of acquisition-related costs of the Mattress Giant acquisition.

The forward-looking statements contained in this press release, such as those relating to our net sales and EPS for fiscal year 2012, are subject to various risks and uncertainties, including but not limited to downturns in the economy and a 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 (including our acquisition of Mattress Giant) 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 31, 2012 filed with the Securities and Exchange Commission (“SEC”) on April 20, 2012 (as amended on May 30, 2012) 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.

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 and bookrunner and a lender, are calculated based on similar measures, which 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.
