All statements that address activities, events or developments that we or our management intend, expect, project, believe or anticipate will or may occur in the future are forward-looking statements. Although we believe forward-looking statements are based upon reasonable assumptions, such statements involve known and unknown risks and uncertainties, which may cause the actual results or performance of the Company to differ materially from such forward-looking statements. Such risks and uncertainties include, but are not limited to, (1) the separation, (2) expected future financial and operating performance of and future opportunities for, ADI following the separation, (3) anticipated benefits of the separation, (4) the tax treatment of the separation, (5) leadership of ADI following the separation, tax rates, tax provisions, cash flows, pension and benefit obligations and funding requirements, our liquidity position or other financial measures, (6) management's plans and strategies for future operations, including statements relating to anticipated operating performance, cost reductions, restructuring activities, new product and service developments, competitive strengths or market position, acquisitions, divestitures, strategic opportunities, securities offerings, stock repurchases, dividends and executive compensation, (7) the effects of the separation or the distribution, if consummated, on our business, (8) growth, declines and other trends in markets we sell into, including the expected impact of trade and tariff policies; new or modified laws, regulations and accounting pronouncements, (9) impact of climate-related events or transition activities; outstanding claims, legal proceedings, tax audits and assessments and other contingent liabilities, (10) foreign currency exchange rates and fluctuations in those rates, (11) impact of changes to tax laws, (12) general economic and capital markets conditions, including expected impact of inflation or interest rate changes, (13) impact of geopolitical events and other hostilities, (14) the timing of any of the foregoing, (15) assumptions underlying any of the foregoing, (16) and any other statements that address events or developments that we intend or believe will or may occur in the future and (17) the other risks described under the headings "Risk Factors" and "Cautionary Statement Concerning Forward-Looking Statements" in Resideo's Annual Report on Form 10-K for the year ended December 31, 2025 and other periodic filings Resideo makes from time to time with the Securities and Exchange Commission. Forward-looking statements are not guarantees of future performance, and actual results, developments, and business decisions may differ from those envisaged by our forward-looking statements. Except as required by law, we undertake no obligation to update such statements to reflect events or circumstances arising after the date of this presentation and we caution investors not to place undue reliance on any such forward looking statements. This presentation contains projections and other forward-looking financial information, including projected revenues, earnings, capital expenditures, and other financial metrics. These projections are based on assumptions that management believes to be reasonable as of the date of this presentation. However, the projections are inherently uncertain and are subject to significant business, economic, regulatory, and competitive risks and uncertainties that could cause actual results to differ materially from those presented. No representation or warranty, express or implied, is made as to the accuracy or completeness of these projections, and recipients of this presentation should not place undue reliance on any such projections. The Company undertakes no obligation to update or revise any projections to reflect events or circumstances arising after the date of this presentation. Basis of Presentation This presentation contains certain financial information that reflects management's estimates of the stand-alone costs, expenses, and operating results of ADI as if it were operating as a separate, independent company. Because this information is based on estimates and assumptions made by management, it is inherently uncertain, and actual results may differ materially from those presented herein. For the fiscal years ended December 31, 2023 and 2024, management has included the operating results of Snap One for the periods prior to its acquisition by ADI which was completed on June 14, 2024. Any pre-acquisition financial information has been combined with ADI's historical financial data for purposes of this presentation; however, Snap One's accounting policies, practices, and classifications may differ from those of ADI, and no pro forma financial information has been prepared in accordance with Article 11 of Regulation S-X. Accordingly, the combined financial information presented for these periods may not be directly comparable to ADI's post-acquisition reported results. In addition, for the three months period ended June 30, 2024 (which is the fiscal quarter in which the acquisition of Snap One by ADI was completed), the pre-acquisition combined financial information of Snap One included in this presentation are based on management estimates and have not been derived from Snap One's historical books and records for that period. Investors and other recipients of this presentation should consider these limitations when evaluating the financial information contained herein and should not place undue reliance on such information as a substitute for audited or reviewed financial statements prepared in accordance with generally accepted accounting principles. Use of Non-GAAP Measures This presentation includes certain "non-GAAP financial measures" as defined under the Securities Exchange Act of 1934 and in accordance with Regulation G thereunder. Management believes the use of such non-GAAP financial measures assists investors in understanding the ongoing operating performance of the Company by presenting the financial results between periods on a more comparable basis. Such non-GAAP financial measures should not be construed as an alternative to reported results determined in accordance with U.S. GAAP. Please see Appendix for further information relating to these non-GAAP financial measures and reconciliations. Market, Industry and Other Information This presentation includes market, industry and other statistical data, as well as estimates and forecasts, from internal research and third-party publications, surveys and studies. Such information involves numerous assumptions and limitations, and you should not place undue weight on these data or estimates. Information contained herein obtained from third-party sources and has not been independently verified. The Company makes no representation or warranty, express or implied, as to the accuracy or completeness of such information. This presentation is provided solely for your information in connection with your evaluation of the Company and is not intended for redistribution, publication or use by any other person.
