MORRIS PLAINS, N.J., November 6, 2025 – Solstice Advanced Materials Inc. (Nasdaq: SOLS) (“Solstice” or “the Company”), a global specialty chemicals and advanced materials company with leading positions in refrigerants, semiconductor materials, protective fibers, and healthcare packaging, today reported financial results for the third quarter of 2025.

“I am excited to report Solstice’s third quarter results, marking our first earnings announcement following our spin-off from Honeywell on October 30,” said David Sewell, President and Chief Executive Officer. “Our performance in the third quarter builds on a foundation of growth and reflects the team’s strong execution throughout the business as we prepared to transition to being an independent entity. We continue to see robust demand, especially in Refrigerants, Electronic Materials, and Safety & Defense Solutions, and were pleased to see the order backlog for Alternative Energy Services accelerate on the back of favorable domestic industry dynamics. Despite certain transitory costs that were expected, and a negative impact from Refrigerants mix during the quarter due to the ongoing regulatory transition, we continue to see healthy margins. With a strong balance sheet and a robust liquidity profile, we believe we are well-positioned to execute our strategy and unleash our full growth potential as an independent company.”

Net Sales in the third quarter of 2025 were $969 million, a 7% increase compared to the third quarter of 2024, reflecting a 9% increase in Net Sales in the Refrigerants & Applied Solutions segment and a 2% increase in Net Sales in the Electronic & Specialty Materials segment. Organic Net Sales1 increased by 5% in the third quarter driven by volume growth and favorable pricing in Refrigerants, partially offset by lower volumes in Healthcare Packaging.

Net Loss attributable to Solstice in the third quarter of 2025 was $35 million, compared to Net Income attributable to Solstice of $152 million in the third quarter of 2024, which includes the impact of higher income tax expense driven by frictional taxes associated with the Company’s spin-off from Honeywell. Adjusted Standalone EBITDA (estimate)1 for the third quarter of 2025 was $235 million, a decrease of 5% compared to the third quarter of 2024. Adjusted Standalone EBITDA Margin (estimate)1 for the third quarter of 2025 decreased 290 basis points to 24.3%. The decline was primarily driven by unfavorable product mix in Refrigerants and anticipated transitory cost items, which more than offset the volume growth, favorable pricing, and favorable currency translation underlying strong top line growth.

Please also refer to tables at the end of this news release for a reconciliation of historical non-GAAP measures and ratios to the most directly comparable GAAP measure.

Capital Expenditures for the nine months ended September 30, 2025 were $248 million, a 23% increase compared to the prior-year period due to planned increases in capital spending to drive long-term growth as outlined at the Company’s recent Investor Day.

Adjusted Standalone EBITDA (estimate) - capex1 for the nine months ended September 30, 2025 was $520 million, a 7% decrease compared to the prior-year period. The decrease in Adjusted Standalone EBITDA (estimate) - capex1 was primarily driven by the increase in Capital Expenditures, partially offset by the increase in Adjusted Standalone EBITDA (estimate)1.

Following the execution of the spin-off, the Company’s Total Long-Term Debt was $2.0 billion and Cash and Cash Equivalents were approximately $450 million. As a result, the Company estimates its Net Leverage ratio was approximately 1.5x based on a trailing twelve-month Adjusted Standalone EBITDA (estimate)1. Total liquidity was approximately $1.5 billion, including Cash and Cash Equivalents and $1.0 billion of availability through the Company’s revolving credit facility.

Net Sales for the Refrigerants & Applied Solutions segment were $687 million in the third quarter of 2025, up 9% compared to the third quarter of 2024. Net Sales in Refrigerants increased 22% in the third quarter of 2025 compared to the third quarter of 2024, reflecting favorable pricing and volume growth due to strong demand. This increase was partially offset by a 14% decline in Net Sales in Healthcare Packaging driven by lower volumes. During the third quarter, the Alternative Energy Services backlog increased $0.2 billion, or 12%, to $2.2 billion as of September 30, 2025.

Segment Adjusted EBITDA for the Refrigerants & Applied Solutions segment decreased 3% in the third quarter of 2025 compared to the third quarter of 2024. Segment Adjusted EBITDA Margin for the segment decreased 431 basis points compared to the third quarter of 2024. The decrease was primarily driven by stationary refrigerants product mix as a result of the ongoing transition to low global warming potential refrigerants. This decrease was partially offset by volume growth and favorable pricing.

Please also refer to tables at the end of this news release for a reconciliation of historical non-GAAP measures and ratios to the most directly comparable GAAP measure.

Net Sales for the Electronic & Specialty Materials segment were $282 million in the third quarter of 2025, up 2% compared to the third quarter of 2024. Growth was primarily driven by a 6% increase in Safety & Defense Solutions and a 4% increase in Electronic Materials attributable to volume growth in both businesses as well as favorable foreign currency translation. This increase was partially offset by a 2% decline in Research & Performance Chemicals due to lower volumes more than offsetting favorable pricing.

Segment Adjusted EBITDA for the Electronic & Specialty Materials segment decreased 15% in the third quarter of 2025 compared to the third quarter of 2024. Segment Adjusted EBITDA Margin for the segment decreased 319 basis points compared to the third quarter of 2024. The decrease was primarily driven by anticipated transitory cost items.

Corporate Expenses totaled $54 million in the third quarter of 2025, compared to $33 million in the third quarter of 2024. The change primarily reflects increased costs associated with the Company’s transition to operating on a standalone basis, including for personnel in a number of Corporate functions. This increase is directly correlated with a corresponding decrease in estimated incremental ongoing standalone costs to be incurred.

Income Tax Expense was $182 million, an increase of $133 million compared to the third quarter of 2024 due to frictional taxes associated with the Company’s separation from Honeywell.

Solstice is reaffirming its full-year 2025 financial guidance as outlined at the Company’s recent Investor Day.

For full-year 2025, Solstice expects the following:

•Net Sales between $3.75 billion and $3.85 billion;

•Adjusted Standalone EBITDA Margin (estimate)1 of approximately 25%; and

•Capital Expenditures between $365 million and $415 million.

“Driven by strong demand and bolstered by our operational excellence, we are on track to deliver on our full-year commitments,” said David Sewell, President and Chief Executive Officer. “We look forward to driving long-term value for all our stakeholders as we focus on our attractive end markets, grow our industry-leading technology platforms, and execute on our strategy as an independent company.”

The Company uses non-GAAP financial measures to supplement the financial measures prepared in accordance with U.S. GAAP. These include (1) Organic sales percentage, (2) Adjusted EBITDA, (3) Adjusted EBITDA Margin, (4) Adjusted Standalone EBITDA (estimate), (5) Adjusted Standalone EBITDA margin (estimate), (6) Adjusted Standalone EBITDA (estimate) - capex, (7) Cash conversion, (8) Net debt, (9) Total leverage ratio, and (10) Net leverage ratio.

Below are definitions and reconciliations of certain non-GAAP financial measures to the most directly comparable financial measures calculated and presented in accordance with U.S. 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. Management believes these non-GAAP financial measures provide investors with a meaningful measure of its performance period to period, align the measures to how management evaluates performance internally, and make it easier for investors to compare our performance to peers. These measures should be considered in addition to, and not as replacements for, the most directly comparable U.S. GAAP measure. The non-GAAP financial measures we use are as follows:

•Organic sales percentage: The Company defines organic sales percentage as the year-over-year change in reported sales relative to the comparable period, excluding the impact on sales from foreign currency translation and acquisitions, net of divestitures, for the first 12 months following the transaction date. We believe this measure is useful to investors and management in understanding our ongoing operations and in analysis of ongoing operating trends.

•Adjusted EBITDA, Adjusted EBITDA margin, Adjusted Standalone EBITDA (estimate), and Adjusted Standalone EBITDA margin (estimate): The Company defines 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). The Company defines Adjusted EBITDA Margin as Adjusted EBITDA divided by Net sales. The Company defines 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 were transferred to the Company in connection with the spin-off. The Company defines 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: The Company defines Adjusted Standalone EBITDA (estimate) - capex as Adjusted Standalone EBITDA (estimate) less capital expenditures. The Company defines 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: The Company defines net debt as total debt less cash. The Company defines total leverage ratio as total debt divided by Adjusted EBITDA. The Company defines net leverage ratio as net debt divided by Adjusted EBITDA. For purposes of showing total leverage ratio and net leverage ratio as expected, 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.
