Disclaimer Forward-Looking Statements This presentation and the related conference call contain "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, Section 21E of the Securities Exchange Act of 1934, and the "safe harbor" provisions under the Private Securities Litigation Reform Act of 1995. 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) our ability to achieve our outlook regarding the first quarter 2026 and full year 2026, (2) risks related to our anticipated separation of Resideo Technologies' Products & Solutions and ADI Global Distribution businesses into two independent publicly traded companies, including the timing thereof and that we may experience operational or other disruptions as a result of the separation and the planning therefor, (3) our ability to recognize the expected savings from, and the timing and impact of, our existing and anticipated cost reduction actions, and our ability to optimize our portfolio and operational footprint, (4) the amount of our obligations and nature of our contractual restrictions pursuant to, and disputes that have or may hereafter arise under the agreements we entered into with Honeywell in connection with our spin-off, (5) the ability of Resideo to drive increased customer value and financial returns and enhance strategic and operational capabilities, (6) risks and uncertainties relating to tariffs that have been or may be imposed by the United States and other governments, and (7) the other risks described under the headings "Risk Factors" and "Cautionary Statement Concerning Forward-Looking Statements" in our Annual Report on Form 10-K for the year ended December 31, 2025 and other periodic filings we make 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 the Company 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 the Company which was completed on June 14, 2024. Any pre-acquisition financial information has been combined with the Company's historical financial data for purposes of this presentation. In addition, for the three months period ended June 30, 2024 (which is the fiscal quarter in which the acquisition of Snap One by the Company 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. For the fiscal year ended December 31, 2025, management has included an adjustment to revenue of $174.9 million to account for intercompany sales between Resideo Technologies' Products & Solutions and ADI Global Distribution businesses that would have been recognized if they had been third-party sales. 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.
