Thanks for your outstanding contributions to the company. Tempur has made incredible progress over the past two years and we know how much work went into that.

Over That Same Time Period, Mattress Peers Select Comfort and Simmons Co.

Total shareholder return includes stock price appreciation and dividends reinvested. Note 2:  Represents performance from December 19, 2007 to December 19, 2008.

Note 5:  During 2008-2014, the Company’s reported net income under U.S. generally accepted accounting principles ("GAAP") grew at a 10.8% CAGR and GAAP EPS grew at a 14.2% CAGR. Adjusted EBITDA and Adjusted EPS are not recognized terms under GAAP and do not purport to be alternatives to GAAP net income or GAAP EPS. Management believes that the use of Adjusted EPS and Adjusted EBITDA provide investors with additional useful information with respect to the operating performance of the Company, and the impact of costs associated with   the Sealy acquisition, and (where applicable) the disposal of three U.S. innerspring component facilities, the accelerated amortization of deferred financing charges for voluntary debt prepayment of Term A and Term B loans, other income related to certain other non-recurring   items, including income from a partial settlement of a legal dispute, and adjustment of taxes to a normalized tax rate related to the aforementioned items as well as other discrete income tax events. In addition, the use of Adjusted EBITDA provides investors with additional useful   information with respect to the Company’s senior secured credit facility and covenant compliance. For a reconciliation of Adjusted EBITDA and Adjusted EPS to the applicable GAAP information please refer to “Reconciliation of Non-GAAP Financial Measures”. +95% Strong Financial Performance (2008 – 2014 CAGR) +21.5% +15.2% +18.9% Adj.

EBITDA/Adjusted EBITDA Management believes that the use of EBITDA and adjusted EBITDA provides investors with useful information with respect to the terms of the Company’s senior secured credit facility and the Company’s compliance with key financial covenants. For more information regarding the types of reconciling adjustments made between these non-GAAP financial measures and the corresponding GAAP information set forth above under “Reconciliation of Non-GAAP Financial Measures”, please refer to the Company’s SEC filings, including the Company’s report on Form 8-K filed on February 5, 2015. 9 TEMPUR SEALY INTERNATIONAL, INC.
