Many of these statements appear, in particular, under the heading "Management's Discussion and Analysis of Financial Condition and Results of Operations" in Part I, ITEM 2 of this Report. When used in this Report, the words "assumes," "estimates," "expects," "guidance," "anticipates," "might," "projects," "predicts," "plans," "proposed," "targets," "intends," "believes," "will," "may," "could," "is likely to" and variations of such words or similar expressions are intended to identify forward-looking statements. These forward-looking statements are based upon our current expectations and beliefs and various assumptions. There can be no assurance that we will realize our expectations or that our beliefs will prove correct.

Numerous factors, many of which are beyond the Company's control, could cause actual results to differ materially from any that may be expressed herein as forward-looking statements in this Report. These risk factors include the impact of the macroeconomic environment including its impact on consumer behavior in both the U.S. and internationally on our business segments and expectations regarding growth of the mattress industry; changes in economic conditions, including inflationary trends in the price of raw materials; uncertainties arising from global and geo-political events (including the war in Ukraine and the war in the Middle East) and any related effect on pricing, sales and supply of materials, labor costs and other employment-related costs; the imposition of new tariffs and retaliatory tariffs, increases in existing tariffs and other changes in trade policy and regulations; loss of suppliers and disruptions in the supply of raw materials; competition in our industry; the effects of strategic investments on our operations, including our efforts to expand our global market share and actions taken to increase sales growth including the acquisition of Mattress Firm; expectations regarding post-closing supply agreements, future performance, synergies and integration of acquired companies with our business, including Mattress Firm; the ability to close the pending Leggett & Platt acquisition, which depends on the satisfaction of customary closing conditions, including approval by Leggett & Platt's shareholders and receipt of applicable regulatory approvals; the ability to successfully integrate Mattress Firm and Leggett & Platt into the Company's operations and realize all synergies from the transactions; the possibility that the expected benefits of the Mattress Firm and Leggett & Platt acquisitions are not realized when expected or at all; general economic, financial and industry conditions, particularly conditions relating to the financial performance and related credit issues present in the retail sector, as well as consumer confidence and the availability of consumer financing; the ability to develop and successfully launch new products; capital project timelines; the ability to realize all synergies and benefits of acquisitions (including the mergers with Mattress Firm and Leggett & Platt); our reliance on information technology ("IT") and the associated risks involving realized or potential security lapses and/or cyber based attacks; the impact of cybersecurity incidents on our business, results of operations or financial condition, including our assessments of such impact; the Company's ability to restore its critical operational data and IT systems in a reasonable time frame following a cybersecurity incident; changes in interest rates; effects of changes in foreign exchange rates on our reported earnings; expectations regarding our target leverage and our share repurchase program; compliance with regulatory requirements and the possible exposure to liability for failures to comply with these requirements; the outcome of pending tax audits or other tax, regulatory or investigation proceedings and pending litigation; changes in foreign tax rates and changes in tax laws generally, including the ability to utilize tax loss carryforwards and the H.R. 1 tax act ("Tax Act"); and our capital structure and debt level, including our ability to meet financial obligations and continue to comply with the terms and financial ratio covenants of our credit facilities.

Other potential risk factors include the factors discussed in our Annual Report on Form 10-K for the year ended December 31, 2025 (the "2025 Annual Report"). In addition, there may be other factors that may cause our actual results to differ materially from the forward-looking statements.
