November 2018 Investor Presentation Exhibit 99.1

Non-GAAP Financial Measures This presentation includes Adjusted EBITDA, Adjusted EBITDA including environmental indemnification payments, Adjusted EBITDA Margin, Segment Profit, Segment Profit Margin and other financial measures not compliant with generally accepted accounting principles in the United States (GAAP). The non-GAAP financial measures provided herein are adjusted for certain items as presented in the Appendix and may not be directly comparable to similar measures used by other companies in our industry, as other companies may define such measures differently. Management believes that, when considered together with reported amounts, these measures are useful to investors and management in understanding our ongoing operations and in analysis of ongoing operating trends. These metrics should be considered in addition to, and not as replacements for, the most comparable GAAP measure. Refer to the Appendix attached to this presentation for reconciliations of non-GAAP financial measures to the most directly comparable GAAP measures. We believe EBITDA, Adjusted EBITDA, Adjusted EBITDA including environmental indemnification payments, Adjusted EBITDA Margin, Segment Profit, and Segment Profit Margin are important indicators of operating performance which more closely measure our operating profit. A reconciliation of Adjusted EBITDA and Adjusted EBITDA Margin to the closest GAAP financial measure is not available without unreasonable efforts on a forward-looking basis due to the impact and timing on future operating results arising from items excluded from these measures, particularly standalone costs, environmental indemnification reimbursement expense, non-operating (income) expense, stock compensation expense and repositioning charges. For additional information with respect to our Unaudited Combined Financial Statements, see our Form 10.

Cash Reimbursement Payments to Honeywell Capped at $140M in Respect of Any Year Indemnification and Reimbursement Overview and Impact Background Honeywell is responsible for the environmental remediation of ~230 sites or groups of sites currently undergoing environmental remediation On the effective date, Resideo will enter into an Indemnification and Reimbursement Agreement (Reimbursement Agreement) with Honeywell Resideo will have obligation to make cash payments to Honeywell related to the remediation of the sites subject to the agreement, up to 90% of cash payments made by Honeywell less 90% of Honeywell’s net insurance receipts and less 90% of certain other specified amounts received by Honeywell Indemnity Obligation Payments subject to a cap of $140M in respect of any year (exclusive of any late payment fees up to 5% per annum) plus any deferred amounts Indemnity payment will be subject to compliance with financial covenants in credit agreement and is subordinated to all material indebtedness Agreement for a duration of 25 years, up to December 31, 2043, or 3rd consecutive year during which the annual indemnity payment obligations are less than $25M Honeywell’s Net Liability Upon spin, Resideo recognizes a liability to account for the contingent aspect of the indemnification and carries over Honeywell’s historical basis of the underlying obligation being indemnified As of June 30, 2018, the Company would have approximately $640M of liability under the Reimbursement Agreement Based on the Reimbursement Agreement, the liability will generally be recorded at 90% of Honeywell’s accrued liability (net of 90% of insurance receipts and certain other specified amounts) Quarterly meetings between Honeywell counsel managing liability and Resideo counsel to discuss claims experience P&L Impact Resideo will generally record 90% of the costs recorded by Honeywell Honeywell accrues noncash expense related to environmental matters when it is probable that it has incurred a liability and the amount can be reasonably estimated Note: Expense was $282M in 2017; Averaged ~$215M over last three years Cash Flow Impact Resideo will record an operating cash outflow for amounts paid to Honeywell in respect of a given year not to exceed the $140M cap plus any late payment amounts accruing if Resideo is subject to a specified event of default under certain indebtedness or is not compliant with certain financial covenants in certain indebtedness on a pro forma basis, provided these conditions are not continuing at this time of payment Tax Treatment Resideo’s payments to Honeywell will not be tax deductible by Resideo

Note: Margins calculated as % of net sales. 1 Assumed cash paid for the environmental obligations subject to the cap of $140M in respect of a year in accordance with the terms of the Indemnification and Reimbursement Agreement. Independent of the Indemnification and Reimbursement Agreement, Resideo will have ongoing liability for certain environmental claims which are part of SpinCo’s going forward business. For 2017 these payments totaled ~$1.1M. Net Loss to EBITDA Reconciliation | (US$ in Millions) Reconciliation Commentary 1 Represents historical environmental expenses as reported under 100% carryover basis Represents the difference between Resideo’s estimate of Selling, general and administrative costs as a stand-alone company and historical allocated costs. The preliminary estimates is ~$265M on an annual basis, which replaces the historical allocations on a carve-out basis of presentation Stock compensation expense adjustment includes only non-cash expenses Non-operating income / expense adjustment excludes net interest income / expenses On a going forward basis, pursuant to the Indemnification and Reimbursement Agreement Resideo expects to indemnify Honeywell in amounts equal to 90% of payments.
