33 Impact of Mattress Firm acquisition ACQUISITION AND DIVESTITURE • The acquisition of Mattress Firm on February 5th • The divestiture of 103 Sleep Outfitters and 73 Mattress Firm stores on May 1st • The elimination of intercompany sales between Mattress Firm and Tempur Sealy, which is expected to be approximately 18% of global Tempur Sealy sales in 2025 • Tempur Sealy has historically accounted for store occupancy costs in operating expense. It is now treated as COGS. This will result in an approximate 150 basis point headwind to North America’s gross margin and an 800 basis point headwind to International’s gross margin year over year • Mattress Firm has historically accounted for co-operative advertising dollars provided by Tempur Sealy as a reduction to COGS. It is now treated as a reduction to advertising expense. Tempur Sealy continues to account for all co-operative advertising investments in Advertising expense P&L LANDSCAPING PURCHASE PRICE ACCOUNTING • Approximately $15 million of incremental expense associated with the step up to fair value of the acquired Mattress Firm business, which will primarily impact Mattress Firm COGS SYNERGIES • Expected first year synergy benefits of $15M, primarily realized in the back half of the year, with an expected ramp in subsequent years 2025 OUTLOOK7

LONG TERM PERSPECTIVE7 34 2026-2028 Adjusted EPS2 INTERNAL TARGETS3 • We are internally targeting sales to grow at a compound annual rate of mid single digits starting in 2025. • This indicates adjusted EPS2 would increase from the $2.50 midpoint for 2025 to approximately $4.85 by 2028, a compound annual growth rate of 25%. $2.50 $4.85 $0.00 $2.00 $4.00 $6.00 2025 2028

44 In this investor presentation and certain of its press releases and SEC filings, the Company provides information regarding adjusted net income, adjusted EPS, EBITDA, adjusted EBITDA, free cash flow, consolidated indebtedness less netted cash, and leverage, which are not recognized terms under U.S. Generally Accepted Accounting Principles (“GAAP”) and do not purport to be alternatives to net income and earnings per share as a measure of operating performance, an alternative to cash provided by operating activities as a measure of liquidity, or an alternative to total debt. The Company believes these non-GAAP measures provide investors with performance measures that better reflect the Company’s underlying operations and trends, including trends in changes in margin and operating expenses, providing a perspective not immediately apparent from net income and operating income. The adjustments management makes to derive the non-GAAP measures include adjustments to exclude items that may cause short-term fluctuations in the nearest GAAP measure, but which management does not consider to be the fundamental attributes or primary drivers of the Company’s business. The Company believes that exclusion of these items assists in providing a more complete understanding of the Company’s underlying results from continuing operations and trends, and management uses these measures along with the corresponding GAAP financial measures to manage the Company’s business, to evaluate its consolidated and business segment performance compared to prior periods and the marketplace, to establish operational goals and management incentive goals, and to provide continuity to investors for comparability purposes. Limitations associated with the use of these non-GAAP measures include that these measures do not present all the amounts associated with the Company’s results as determined in accordance with GAAP. These non-GAAP measures should be considered supplemental in nature and should not be construed as more significant than comparable measures defined by GAAP. Because not all companies use identical calculations, these presentations may not be comparable to other similarly titled measures of other companies. For more information regarding the use of these non-GAAP financial measures, please refer to the reconciliations on the following pages and the Company’s SEC filings. EBITDA and Adjusted EBITDA A reconciliation of the Company’s GAAP net income to EBITDA and adjusted EBITDA per credit facility is provided on the subsequent slides. Management believes that the use of EBITDA and adjusted EBITDA per credit facility provides investors with useful information with respect to the Company’s operating performance and comparisons from period to period as well as the Company’s compliance with requirements under its credit agreement. Adjusted Net Income and Adjusted EPS A reconciliation of the Company’s GAAP net income to adjusted net income and a calculation of adjusted EPS are provided on subsequent slides. Management believes that the use of adjusted net income and adjusted EPS also provides investors with useful information with respect to the Company’s operating performance and comparisons from period to period. Forward-looking Adjusted EPS is a non-GAAP financial measure. The Company is unable to reconcile this forward-looking non-GAAP measure to EPS, its most directly comparable forward-looking GAAP financial measure, without unreasonable efforts, because the Company is currently unable to predict with a reasonable degree of certainty the type and extent of certain items that would be expected to impact EPS in 2025. Leverage Consolidated indebtedness less netted cash to adjusted EBITDA per credit facility, which the Company may refer to as leverage, is provided on a subsequent slide and is calculated by dividing consolidated indebtedness less netted cash, as defined by the Company’s senior secured credit facility, by adjusted EBITDA per credit facility. The Company provides this as supplemental information to investors regarding the Company’s operating performance and comparisons from period to period, as well as general information about the Company's progress in managing its leverage.
