HOUSTON, June 9, 2016 /BUSINESSWIRE/ — Mattress Firm Holding Corp. (the “Company”) (NASDAQ: MFRM), the nation’s largest specialty mattress retailer, today announced its financial results for the first fiscal quarter (13 weeks) ended May 3, 2016.  Net sales for the first fiscal quarter increased 49.2% over the prior year period to $839.4 million, reflecting incremental sales from acquired and new stores, partially offset by a comparable-store sales decline of 1.1%. The Company reported first fiscal quarter earnings (loss) per diluted share (“EPS”) on a generally accepted accounting principles (“GAAP”) basis of $(3.22), and EPS on a non-GAAP adjusted basis, excluding intangible asset impairment charges, acquisition-related costs, fixed asset impairment costs and severance charges (“Adjusted”), of $(0.17).  Excluding the non-cash amortization of tradenames, Adjusted EPS excluding Tradename Amortization was $(0.10), compared with the Company’s guidance for $(0.07) to $0.00 in Q1.

Expected diluted EPS on a GAAP basis, adjusted basis and adjusted basis excluding tradename amortization are reconciled in the table below:

“We are disappointed in our first quarter results, as we experienced unrelated challenges in three primary areas,” stated Steve Stagner, executive chairman and chairman of the board. “These issues have been resolved and are largely behind us, however, there was clearly an impact to sales in Q1 that continued early into Q2.  Due to our results to date, we are revising our guidance for the full year.”

Mr. Stagner concluded, “Trends have returned to positive low-single digit comparable-store sales growth over Memorial Day and in the days since the holiday, in-line with our revised guidance for the remainder of the year.  This gives us additional confidence that we have put these obstacles behind us.  Despite a challenging quarter, I am proud to say that our team worked tirelessly to move the organization past these challenges, and we are now better positioned to execute on our long-term strategy, as we build a national chain under the Mattress Firm brand.”

Preliminary First Quarter Financial Summary

·                  Net sales for the first fiscal quarter increased 49.2% as compared with the comparable prior year period to $839.4 million, reflecting incremental sales from acquired and new stores, partially offset by a comparable-store sales decline of 1.1%. Comparable-store sales growth in the prior year period was 1.3%.

·                  The Company acquired 1,065 stores, opened 85 new stores and closed 37 stores, bringing the total number of Company-operated stores to 3,472 as of the end of the fiscal quarter.

·                  Loss from operations was $167.7 million. Excluding a total of $181.4 million of intangible asset impairment charges, acquisition-related costs, fixed asset impairment costs and severance charges, Adjusted income from operations was $13.7 million, as compared with $29.0 million for the comparable prior year period.  Adjusted operating income margin was 1.6% of net sales as compared to 5.2% in the first fiscal quarter of 2015, and included a 280 basis-point decline in gross margin, an 80 basis-point decrease from sales and marketing expense deleverage, and 20 basis-points of combined operating margin declines from franchise fees and losses on store closings, partially offset by a 20 basis-point improvement in general and administrative expense leverage. Please refer to “Reconciliation of Reported (GAAP) to Adjusted Statements of Operations Data” for a reconciliation of income from operations to Adjusted income from operations and other information.

·                  Net loss attributable to Mattress Firm Holding Corp. was $119.2 million and GAAP EPS was $(3.22).  Excluding $112.7 million, net of income taxes, of intangible asset impairment charges, acquisition-related costs, fixed asset impairment costs and severance charges, Adjusted net loss was $6.5 million and Adjusted EPS was $(0.17). Please refer to “Reconciliation of Reported (GAAP) to Adjusted Statements of Operations Data” for a reconciliation of net income (loss) and GAAP EPS to Adjusted net income (loss) and Adjusted EPS, respectively, and other information.

Announces Plan to Consolidate All Stores Under the Mattress Firm Banner Nationwide

The Company decided in late April 2016 to rebrand all of its stores operating under different brand names to the Mattress Firm brand name over the next approximately 12 to 18 months. The Company expects to largely complete this rebranding by the first fiscal quarter of 2017. In connection with this decision, the Company revalued certain of the tradename intangible assets held by the Company and recorded the corresponding non-cash impairment charge of $138.7 million in the first fiscal quarter to write down these intangible assets to fair value. The remaining value of the tradename intangible assets will be amortized over the period of the transition to one nationwide banner.

Real Estate Optimization

The Company continues to review its real estate portfolio as part of the real estate optimization strategy announced on March 21, 2016.  The Company plans to provide an update on this process on its second quarter earnings call in early September.  After completion of its store optimization review, the Company will provide the estimated number of store closings and related costs.  This store optimization effort is expected to drive a more efficient deployment of capital under one national banner going forward.

Balance Sheet

The Company had cash and cash equivalents of $1.1 million on May 3, 2016, the end of the fiscal first quarter.  Net cash provided by operating activities was $7.2 million for the first fiscal quarter. As of May 3, 2016, there were $95.0 million in borrowings outstanding under the revolving portion of the Senior Credit Facility (as defined in the Company’s filings with the Securities and Exchange Commission) and approximately $12.3 million in outstanding letters of credit, with additional borrowing capacity of $64.2 million.

Financial Guidance

The Company is providing updated financial guidance for the full fiscal year (52 weeks) ending January 31, 2017 (“fiscal 2016”) based on business trends to date and expectations for the remainder of fiscal 2016.  These projections are forecasts and are intended solely to give investors an understanding of management’s expectations for the full fiscal year in light of recent conditions and strategies.  The projections do not take into account, or give effect for, any acquisitions that may be completed by the Company during the fiscal year or any other events that are beyond the Company’s reasonable control.  Please refer to “Reconciliation of Reported (GAAP) to Adjusted Statements of Operations Data” for a reconciliation of GAAP EPS to Adjusted EPS and other information which is not calculated on a GAAP basis. Adjusted data for future periods reflects management’s reasonable estimates of appropriate adjustments based on historical experience.

(1)         Before any incremental closures under the proposed real estate optimization program announced on March 21, 2016.

(2)         Based on midpoint of range for the 52 weeks ended January 31, 2017.

Sleepy’s quarterly sales mix is similar to that of Mattress Firm’s legacy businesses.  However, the expected profitability (as illustrated by Adjusted EBITDA) of the Sleepy’s business differs dramatically by quarter, with approximately breakeven first quarter and 80% to 85% of profitability generated during the second and third quarters.  As a result of the impact of incorporating the Sleepy’s business into the Company’s consolidated results, the Company plans to provide quarterly earnings guidance in connection with its regular earnings announcements throughout fiscal 2016 to provide additional insight.  The Company anticipates returning to its historical practice of only providing annual guidance in fiscal 2017.  For the second quarter, the Company anticipates GAAP EPS of $0.27 to $0.32, and Adjusted EPS before Tradename Amortization of $0.62 to $0.69.

In many cases, you can identify forward-looking statements by terminology such as “may,” “would,” “should,” “could,” “forecast,” “feel,” “project,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “predict,” “intend,” “potential,” “continue” or the negative of these terms or other comparable terminology; however, not all forward-looking statements contain these identifying words. 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 2016 and any anticipated effects of any recent acquisitions, 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 largest 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 February 2, 2016 filed with the U.S. Securities and Exchange Commission (“SEC”) on April 4, 2016 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 (loss) before income tax expense (benefit), 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 Senior Credit Facility, are calculated based on similar measures and differ from Adjusted EBITDA primarily by the inclusion of pro forma results for acquired businesses and new stores

5

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 (loss) 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 $2.1 million of reduction of workforce severance expense incurred during the thirteen weeks ended May 3, 2016 and $0.7 million of ERP system implementation training costs incurred during the thirteen weeks ended May 5, 2015.

Adjusted EPS and the other “Adjusted” data provided in this press release, including Adjusted EPS Excluding Tradename Amortization, 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.

The adjustments for the thirteen weeks ended May 3, 2016 were tax effected using our annualized effective tax rate as of May 3, 2016 of 37.9%.

(1)       Reflects approximately $138.7 million of non-cash impairment of tradenames recorded in the thirteen weeks ended May 3, 2016. We decided in late April 2016 to rebrand all of our stores operating under different brand names to the Mattress Firm brand name.  In conjunction with this decision, we revalued all of our tradename intangible assets held by us and recorded the corresponding non-cash impairment charge to write down these assets to fair value.

(2)       On October 20, 2014, we acquired 100% of the outstanding equity interests in The Sleep Train, Inc., related to the operations of 314 mattress specialty retail stores in California, Oregon, Washington, Nevada, Idaho and Hawaii. On January 6, 2015, we acquired substantially all of the mattress specialty retail assets and operations of Sleep America LLC (“Sleep America”), which operated approximately 45 Sleep America retail stores in Arizona. On January 13, 2015 we acquired substantially all of the mattress specialty retail assets and operations of Mattress World, Inc. (“Mattress World”), related to the operation of 4 mattress specialty retail stores under the brand Mattress World in Pennsylvania. On November 17, 2015, we acquired the assets and operations of Double J-RD, LLC, including nine mattress specialty retail stores located primarily in East Texas.  On February 5, 2016, we acquired 100% of the outstanding equity interests in HMK Mattress Holdings LLC, the holding company of Sleepy’s LLC and related entities, related to the operation of 1,065 mattress specialty retail stores in 17 states in the Northeast, New England, the Mid-Atlantic and Illinois.  Acquisition-related costs, which are included in the “As Reported” results of operations, consist of acquisition-related costs as defined under U.S. GAAP, including advisory, legal, accounting, valuation, and other professional or consulting fees and, in addition, costs of integrating store and warehouse operations and corporate functions that are not expected to recur as acquisitions are absorbed. Acquisition-related costs, consisting of direct transaction costs and integration costs, are included in the results of operations as incurred. We incurred approximately $9.2 million and $31.6 million of acquisition-related costs during the thirteen weeks ended May 5, 2015 and May 3, 2016, respectively.

(3)       Reflects approximately $8.9 million of impairment of store and other fixed assets recorded in the thirteen weeks ended May 3, 2016, primarily related to our plan to close certain stores near the end of their lease term.

(4)       Reflects implementation costs included in the results of operations as incurred, consisting primarily of incremental training-related costs, related to the roll-out of the Microsoft Dynamics AX for Retail ERP system. During the thirteen weeks ended May 5, 2015, we incurred approximately $0.7 million of ERP system implementation training costs.

(5)       Reflects approximately $0.3 million for the thirteen weeks ended May 5, 2015 of costs borne by us in connection with a secondary offering of common stock by certain of our selling shareholders which was completed in April 2015. No offering proceeds were received by the Company.

(6)       Reflects severance expense resulting from the beginning of our integration of the Sleepy’s and Mattress Firm’s management structure recorded in the thirteen weeks ended May 3, 2016.

(7)       The remaining value of the finite lived tradename intangible assets will be amortized over the period of the transition to one nationwide banner.

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.
