Business Overview and Basis of Presentation	Business Overview and Basis of Presentation About the Business Solstice Advanced Materials Inc. (“Solstice,” the “Business” or the “Company”) is a global specialty chemicals and advanced materials company with leading positions in refrigerants, semiconductor materials, protective fibers, and healthcare packaging. Prior to October 30, 2025, the Company was wholly owned by Honeywell International Inc. (“Honeywell” or “Parent”). On October 8, 2024, Honeywell announced its plan to spin off its Advanced Materials business into an independent, U.S. publicly traded company through a pro rata distribution of all of the outstanding common shares of Solstice Advanced Materials to Honeywell shareowners (the “Spin-off”) that would be tax-free for U.S. federal tax purposes. On October 30, 2025, the Spin-off was consummated by means of a pro-rata distribution (the “Distribution”), which was intended to be tax-free for U.S. federal tax purposes, of all of the issued and outstanding Solstice Advanced Materials common shares to Honeywell’s shareowners of record as of October 17, 2025 (the “Record Date”), at which time each holder of Honeywell's common shares received one Solstice Advanced Materials common share for every four Honeywell common shares held as of the close of business on the Record Date, resulting in the Distribution of 158,727,456 of the Company’s common shares to Honeywell shareowners. Upon completion of the Distribution, on October 30, 2025, the Company commenced “regular way” trading as an independent public company under the ticker symbol “SOLS” on The Nasdaq Stock Market (“Nasdaq”). Following the Distribution, Honeywell does not beneficially own any Solstice Advanced Materials common shares. Basis of Presentation We prepare our consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”) pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Prior to October 30, 2025 (“the Spin-off date”), the accompanying unaudited combined financial statements have been derived from Honeywell and presented on a standalone basis as if the Company’s operations had been conducted independently. The accompanying financial statements for periods prior to the Spin-off date include all revenues and costs directly attributable to the Solstice Advanced Materials business and an allocation of expenses related to certain Honeywell corporate functions. These expenses were allocated to the Solstice business based on a proportion of net sales. Solstice and Honeywell considered these allocations to be a reasonable reflection of the utilization of services or the benefits received. However, the allocations may not be indicative of the actual expense that would have been incurred had Solstice operated as an independent, standalone entity, nor are they indicative of future expenses of Solstice. Honeywell used a centralized approach to cash management and financing of its operations. Accordingly, for periods prior to the Spin-off, a substantial portion of the Business’s cash accounts were regularly cleared to the former Parent at Honeywell’s discretion and Honeywell funded the Business’s operating and investing activities as needed. Honeywell’s long-term debt and related interest expense were not attributed to Solstice for any of the periods presented as the Business was not the legal obligor of such borrowings and Honeywell’s borrowings were not directly attributable to the Business. All significant intercompany transactions, including transfer of cash, between Solstice and Honeywell prior to the Spin-off were included within Net transfers to Parent on the statements of cash flows and the statements of equity through the pre-Spin-off periods. After the Spin-off date, the Company’s financial statements are consolidated financial statements based on our reported results as a standalone company. All significant transactions between Solstice entities were eliminated. The accompanying financial statements for all periods presented, including the historical results of the Company prior to the Spin-off, are now referred to as “Consolidated Financial Statements.” Certain items have been recast to conform to current-period presentation. We have prepared the accompanying unaudited consolidated financial statements pursuant to the rules and regulations of the SEC applicable to interim financial statements. Accordingly, certain note disclosures have been condensed. These unaudited consolidated financial statements should be read in conjunction with our audited consolidated financial statements, corresponding notes, and significant accounting policies in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025 (the “2025 Annual Report on Form 10-K”). Within the financial statements and tables presented, certain columns and rows may not add due to the use of rounded numbers for presentation and disclosure purposes. Percentages presented are calculated from the underlying whole-dollar amounts. The Company reports its quarterly financial information using a calendar convention; the first, second, and third quarters are consistently reported as ended on March 31, June 30, and September 30, respectively. It is the Company’s practice to establish actual quarterly closing dates using a predetermined fiscal calendar, which requires the Company’s businesses to close their books on a Saturday in order to minimize the potentially disruptive effects of quarterly closing on the Company’s business processes. The effects of this practice are generally not significant to reported results for any quarter and only exist within a reporting year. In the event differences in actual closing dates are material to year-over-year comparisons of quarterly or year-to-date results, the Company will provide appropriate disclosures. The Company’s actual closing dates for the six months ended June 30, 2026, and 2025 were June 27, 2026, and June 28, 2025, respectively.
