The information in this presentation has been prepared in connection with the previously announced plan by Honeywell International Inc. (“HON” or “Honeywell”) to spin off its Advanced Materials business (the “Company”, "Solstice Advanced Materials Inc.“, “Solstice Advanced Materials” or “Solstice”) from information provided by management and other sources. This presentation contains “forward-looking statements” that involve risks and uncertainties. These statements can be identified by the fact that they do not relate strictly to historical or current facts, but rather are based on current expectations, estimates, assumptions and projections about Solstice's industry and its business and financial results. Forward-looking statements often include words such as “anticipates,” “estimates,” “expects,” “projects,” “forecasts,” “intends,” “plans,” “continues,” “believes,” “may,” “will,” “goals” and words and terms of similar substance in connection with discussions of future operating or financial performance. As with any projection or forecast, forward-looking statements are inherently susceptible to uncertainty and changes in circumstances. Solstice’s actual results may vary materially from those expressed or implied in its forward-looking statements. Accordingly, undue reliance should not be placed on any forward-looking statement made by Solstice or on Solstice’s behalf. Although Solstice believes that the forward-looking statements contained in this presentation are based on reasonable assumptions, you should be aware that many factors could affect Solstice’s actual financial results or results of operations and could cause actual results to differ materially from those in such forward-looking statements, including, but not limited to: the ability to effect the proposed spin-off transaction and to meet the conditions related thereto; the possibility that the spin-off transaction will not be completed within the anticipated time period or at all; the possibility that the spin-off transaction will not achieve its intended benefits; the possibility of disruption, including disputes, litigation or unanticipated costs, in connection with the spin-off transaction; the uncertainty of the expected financial performance of Solstice following completion of the spin-off transaction; the ability to achieve anticipated capital structures in connection with the spin-off transaction, including the future availability of credit and factors that may affect such availability; the ability to achieve anticipated credit ratings in connection with the spin-off transaction; the ability to achieve anticipated tax treatments in connection with the spin-off transaction and future, if any, divestitures, mergers, acquisitions and other portfolio changes and the impact of changes in relevant tax and other laws; and the failure to realize expected benefits and effectively manage and achieve anticipated synergies and operational efficiencies in connection with the spin-off transaction and future, if any, divestitures, mergers, acquisitions, and other portfolio management, productivity and infrastructure actions; Solstice’s lack of operating history as an independent, publicly traded company and unreliability of historical combined financial information as an indicator of Solstice’s future results; Solstice’s ability to successfully develop new technologies and introduce new products; changes in the price and availability of raw materials that Solstice uses to produce its products; Solstice’s ability to comply with complex government regulations and the impact of changes in such regulations; global climate change and related regulations and changes in customer demand; the public and political perceptions of nuclear energy and radioactive materials; economic, political, regulatory, foreign exchange and other risks of international operations; the impact of tariffs or other restrictions on foreign imports; Solstice’s ability to borrow funds and access capital markets and any limitations in the terms of Solstice’s indebtedness; Solstice’s ability to compete successfully in the markets in which it operates; the effect on Solstice’s net sales and cash flow from seasonal fluctuations and cyclical market conditions; concentrations of Solstice’s credit, counterparty and market risk; Solstice’s ability to successfully execute or effectively integrate acquisitions; Solstice’s joint ventures and strategic co-development partnerships; Solstice’s ability to recruit and retain qualified personnel; potential material environmental liabilities; the hazardous nature of chemical manufacturing; decommissioning and remediation expenses and regulatory requirements; potential material litigation matters and government proceedings; the impact of potential cybersecurity attacks, data privacy breaches and other operational disruptions; increasing stakeholder interest in public company performance, disclosure, and goal-setting with respect to Environmental, Social, and Governance ("ESG") matters; failure to maintain, protect, and enforce Solstice’s intellectual property or to be successful in litigation related to intellectual property of Solstice or others, or competitors developing similar or superior intellectual property or technology; unforeseen U.S. federal income tax and foreign tax liabilities; U.S. federal income tax reform; Solstice’s ability to operate as an independent, publicly traded company without certain benefits available to Solstice as a part of Honeywell; Solstice’s inability to maintain intellectual property agreements; timing, declaration, amount and payment of Solstice’s dividend program; potential cash contributions to benefit pension plans; Solstice’s ability to maintain proper and effective internal controls; and certain factors discussed elsewhere in this presentation. These risks could cause actual results to differ materially from those implied by forward-looking statements in this presentation, in Solstice's Form 10 Registration Statement, as amended, and its other filings with the Securities and Exchange Commission (the "SEC"). Even if Solstice’s results of operations, financial condition and liquidity and the development of the industry in which we operate are consistent with the forward-looking statements contained in this presentation, those results or developments may not be indicative of results or developments in subsequent periods. Any forward-looking statements made by us in this presentation speak only as of the date on which they are made. We are under no obligation to, and expressly disclaim any obligation to, update or alter Solstice’s forward-looking statements, whether as a result of new information, subsequent events or otherwise. Non-GAAP Financial Measures This presentation contains financial measures presented on a non-GAAP basis. The non-GAAP financial measures used in this presentation are as follows: Adjusted EBITDA, on a total company basis; Adjusted EBITDA margin, on a total company basis; Adjusted Standalone EBITDA (estimate); Adjusted Standalone EBITDA Margin (estimate); Adjusted Standalone EBITDA (estimate)- capex; Cash conversion; Net debt, Net leverage ratio, and Return on invested capital; if and as noted in the presentation. Management believes that, when considered together with comparable GAAP measures, these non-GAAP measures are useful to investors and management in understanding our ongoing operations and in the analysis of ongoing operating trends. These measures 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 historical reconciliations of non-GAAP financial measures to the most directly comparable GAAP measures. Forward-looking non-GAAP measures are estimated consistent with the relevant definitions and assumptions. We have not reconciled Adj. Standalone EBITDA Margin, Adj. EBITDA, Adj. EBITDA Margin, Adj. Standalone EBITDA (estimate) – Capex and Cash Conversion 2025 full year guidance and medium-term financial outlook, as applicable, because the information needed to reconcile these measures is unavailable due to the inherent difficulty of forecasting the timing or amount of various items that have not yet occurred. Additionally, estimating such future estimated measures and providing a meaningful reconciliation consistent with our accounting policies for future periods requires a level of precision that is unavailable for these future periods and cannot be accomplished without unreasonable effort.

The following information provides definitions and historical reconciliations of certain non-GAAP financial measures presented in this presentation to which this reconciliation is attached to the most directly comparable financial measures calculated and presented in accordance with generally accepted accounting principles (“GAAP”). Management believes that, when considered together with reported amounts, these measures are useful to investors and management in understanding our ongoing operations and in the analysis of ongoing operating trends. These measures should be considered in addition to, and not as replacements for, the most comparable GAAP measure. Certain measures presented on a non-GAAP basis represent the impact of adjusting items net of tax. The tax-effect for adjusting items is determined individually and on a case-by-case basis. Other companies may calculate these non-GAAP measures differently, limiting the usefulness of these measures for comparative purposes. Management does not consider these non-GAAP measures in isolation or as an alternative to financial measures determined in accordance with GAAP. The principal limitations of these non-GAAP financial measures are that they exclude significant expenses and income that are required by GAAP to be recognized in the consolidated financial statements. In addition, they are subject to inherent limitations as they reflect the exercise of judgments by management about which expenses and income are excluded or included in determining these non-GAAP financial measures. Investors are urged to review the reconciliation of the non-GAAP financial measures to the comparable GAAP financial measures and not to rely on any single financial measure to evaluate Solstice Advanced Materials’ business. Adjusted EBITDA, Adjusted EBITDA margin, Adjusted Standalone EBITDA (estimate), and Adjusted Standalone EBITDA margin (estimate) We define Adjusted EBITDA as net income excluding income taxes, depreciation, amortization, interest and other financial charges, other expense, stock compensation expense, pension and other postretirement income (expense), transaction-related costs, repositioning charges, asset retirement obligation accretion, and certain other items that are otherwise of an unusual or non-recurring nature (including but not limited to impairment charges, litigation and insurance settlements, and gains and losses on disposal of assets). We define Adjusted Standalone EBITDA (estimate) as Adjusted EBITDA less estimated recurring and ongoing costs required to operate a new independent public company, and autonomous entity adjustments as well as adjustments for certain other employee compensation expense for employees that have historically been shared with other Honeywell businesses and will be transferred to the Company in connection with the spin-off. We define Adjusted Standalone EBITDA Margin (estimate) as Adjusted Standalone EBITDA (estimate) divided by Net sales. We believe these measures are useful to investors as they provide greater transparency with respect to supplemental information used by management in its financial and operational decision making, as well as understanding ongoing operating trends. Adjusted Standalone EBITDA (estimate) – capex, and cash conversion We define Adjusted Standalone EBITDA (estimate) - capex as Adjusted Standalone EBITDA (estimate) less capital expenditures. We define cash conversion as Adjusted Standalone EBITDA (estimate) - capex divided by Adjusted Standalone EBITDA (estimate). We believe these measures are useful to investors and management as a measure of cash generated by operations that can be used to invest in future growth through new business development activities or acquisitions, pay dividends, repurchase stock, or repay debt obligations prior to their maturities. These measures can also be used to evaluate our ability to generate cash flow from operations and the impact that this cash flow has on our liquidity. Net debt, total leverage ratio and net leverage ratio We define net debt as total debt less cash. We define total leverage ratio as total debt divided by Adjusted EBITDA. We define net leverage ratio as net debt divided by Adjusted EBITDA. For purposes of showing total leverage ratio and net leverage ratio as expected from this Transaction, we use LTM Adjusted Standalone EBITDA (estimate) instead of Adjusted EBITDA. We believe these measures are useful to investors and management in understanding our overall financial condition. Return on Invested Capital We define Return on Invested Capital as Net Operating Profit After Taxes ("NOPAT") (which is defined as Standalone Adjusted EBITDA (estimate), less depreciation and amortization, and tax effected), divided by invested capital, which is calculated as debt less cash and cash equivalents, plus equity, each as calculated on a pro-forma basis as of June 30, 2025, after giving effect to the spin-off and related financing transactions. We believe that return on invested capital offers valuable insight to management, investors, analysts, and other stakeholders as a measure of how effectively the Company generates income from the capital provided by shareholders and creditors.
