MATTRESS FIRM PROVIDES UPDATE

- Reiterates and Tightens Diluted Earnings Per Share Guidance Range for Second Fiscal Quarter -

-      Increases Full Fiscal Year 2012 Diluted Earnings Per Share Guidance -

HOUSTON, TX - July 16, 2012 (BUSINESSWIRE) — Mattress Firm Holding Corp. (NASDAQ: MFRM), a leading retailer of mattresses and accessories in the United States, announced that it is reaffirming and tightening its adjusted diluted earnings per share (EPS) range guidance for the second fiscal quarter ending July 31, 2012 to be $0.38 to $0.40 per share, or $0.27 to $0.29 on a GAAP basis, on revised anticipated net sales in the range of $260 million to $265 million. The Company is also raising its adjusted EPS range for the full fiscal year ending January 29, 2013, which is now expected to be $1.65 to $1.71, or $1.48 to $1.52 on a GAAP basis, on revised anticipated net sales in the range of $1.01 billion to $1.03 billion. The difference between adjusted and GAAP EPS solely reflects the costs related to the recent acquisition of Mattress Giant by the Company.  These acquisition costs remain consistent with the Company’s prior guidance.  Additionally, comparable-store sales for the full fiscal year ending January 29, 2013 are now expected to experience a percentage increase in the high single digits over the prior fiscal year.

Steve Stagner, Mattress Firm’s President and Chief Executive Officer, stated, “We are making significant progress integrating approximately 180 stores that we added in May 2012 from the recent acquisition of Mattress Giant and are pleased with the results in the acquired stores. This acquisition has accelerated our strategy of increasing relative market share in a number of key markets in Texas and Florida. Since January 2011 through the end of the first fiscal quarter ended May 1, 2012, we have opened or acquired approximately 340 stores (including the acquired Mattress Giant stores), representing approximately 58% growth in the Company’s store base.  We believe our ability to reaffirm and raise our earnings expectations in light of the downward pressures on sales experienced during the second fiscal quarter reflects our ability to positively impact our cash flows and earnings through our flexible operating model.  We are also pleased that sales during the key Memorial Day and July 4th holidays met the Company’s expectations.  We remain committed to executing on our growth strategies, which include continuing to selectively expand our store base in underpenetrated markets and providing our customers with great brands to drive our growth, further strengthening our position as the largest specialty bedding retailer in country.”

Revised Net Sales and Diluted Earnings per Share (EPS) Guidance:

*                             Acquisition-related costs resulting from the May 2, 2012 acquisition of MGHC Holding Corporation, the parent company of Mattress Giant Corporation, consisting of direct transaction costs and integration costs, are included in results of operations and GAAP EPS as incurred. Such costs are added back in deriving “As Adjusted” EPS.  “As Adjusted” data is considered a non-U.S. GAAP financial measure and is not in accordance with, or preferable to, GAAP financial data. However, we

are providing this information as we believe it facilitates year-over-year comparisons for investors and financial analysts.
