Forward - Looking Statements & Other Disclaimers This presentation contains “forward - looking statements” within the meaning of the federal securities laws made pursuant to the s afe harbor provisions of the Private Securities Litigation Reform Act of 1995 about us and our industry that involve substantial risks and uncertainties. These statements can be identified by the fact that they do not re lat e strictly to historical or current facts, but rather are based on current expectations, estimates, assumptions and projections about our industry and our business and financial results. Forward - looking statements often include words such as “anticipates,” “estimates,” “expects,” “positioned,” “projects,” “forecasts,” “intends,” “plans,” “continues,” “could,” “believes,” “may,” “will,” “would,” “should,” “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. Our actual results may vary materially from those expressed or implied in our forward - looking statements. Accordingly, undue reliance should not be placed on any forward - looking statement made by us or on our behalf. Although we belie ve that the forward - looking statements contained in this presentation are based on reasonable assumptions, you should be aware that a variety of factors, many of which are difficult to predict and outside of our control, could affect our 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: our limited operating history as an independent, publicly traded company and unreliability of historical consolidated financial information as an indicator of our future results; our ability to successfully develop new technologies and introdu ce new products; an overall decline in the health of the economy and the industries in which we operate, including as a result of inflation, tariffs and other trade barriers and restrictions, market volatility, geopolitic al instability and social unrest, the possibility of an economic downturn or recession or other macroeconomic factors; changes in the price and availability of raw materials that we use to produce our products, including due to factors su ch as supply chain disruptions, including those due to increased energy prices, and the impact of inflation; our ability to comply with complex government regulations and the impact of changes in such regulations; global cl ima te 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 in ternational operations; the impact of tariffs or other restrictions on foreign imports; our ability to borrow funds and access capital markets and any limitations in the terms of our indebtedness; our ability to compete successf ull y in the markets in which we operate; the effect on our revenue and cash flow from seasonal fluctuations and cyclical market conditions; concentrations of our credit, counterparty and market risk; our ability to succe ssf ully execute or effectively integrate potential acquisitions or complete potential divestitures; our joint ventures and strategic co - development partnerships; our ability to recruit and retain qualified personnel; potential material en vironmental liabilities; the hazardous nature of chemical manufacturing; decommissioning and remediation expenses and regulatory requirements; potential material litigation matters, including disputes related to our sp in - off from Honeywell International Inc. (“Honeywell”) completed in October 2025 (the “Spin - Off”); the impact of potential cybersecurity attacks, data privacy breaches and other operational disruptions; increasing stakeholder in ter est in public company performance, disclosure, and goal - setting with respect to sustainability matters; failure to maintain, protect and enforce our intellectual property or to be successful in litigation related to our int ellectual property or the intellectual property of others, or competitors developing similar or superior intellectual property or technology; unforeseen U.S. federal income tax and foreign tax liabilities and our ability to achiev e a nticipated tax treatments in connection with the Spin - off; U.S. federal income tax reform; our ability to operate as an independent, publicly traded company without certain benefits available to us as a part of Honeywell prior to t he Spin - off, including managing the costs of operating as an independent company following the Spin - off; our ability to achieve some or all of the benefits that we expect to achieve from the Spin - off; our inability to maint ain intellectual property agreements; potential timing, declaration, amount and payment of the Company’s dividend program; potential cash contributions to defined benefit pension plans; and our ability to maintain proper an d effective internal controls. These and other factors are more fully discussed in the “Risk Factors” and “Management’s Discussion and Analysis of Financial Co ndition and Results of Operations” sections included in our Annual Report on Form 10 - K for the year ended December 31, 2025, filed with the SEC on February 19, 2026, as may be updated from time to time in our SEC filings . T hese risks could cause actual results to differ materially from those implied by forward - looking statements in this presentation. Even if our 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. The Compa ny does not undertake to update or revise any of its forward - looking statements, which speak only as of the date they are made, except as may be required by law or regulation. Non - GAAP Financial Measures This presentation contains financial measures presented on a non - GAAP basis. The non - GAAP financial measures used in this presen tation are as follows: Adjusted EBITDA, on a total company basis; Adjusted EBITDA margin, on a total company basis; Adjusted Standalone EBITDA; and Adjusted Standalone EBITDA Margin. The Company defines Adjusted EBITDA as net income excluding income taxes, depreciation, amortization, interest and other financial charges, remeasurement of foreign currencies, stock - based compensation expense, pension and other postretirement expen se (income), transaction - related costs, repositioning charges, asset retirement obligations accretion, asset impairment charges, litigation costs and insurance settlements (net of recoveries), gains and losses on disp osa l of assets, and certain other items that are otherwise of an unusual or non - recurring nature. The Company defines Adjusted EBITDA margin as Adjusted EBITDA divided by Net sales. The Company defines Adjusted Standalone EBITD A a s 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 exp ense for employees that have historically been shared with other Honeywell businesses and were transferred to the Company in connection with the Spin - off. The Company defines Adjusted Standalone EBITDA Margin as Ad justed Standalone EBITDA divided by Net sales. When considered together with comparable GAAP measures, these non - GAAP measures are useful to investors and management in unders tanding 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 t he appendix attached to this presentation for historical reconciliations of non - GAAP financial measures to the most directly comparable GAAP measures. 2
