Important Note about Combined and Non-GAAP Financial Information

The financial information for the combined businesses of Solstice and Element Solutions is based on management's estimates, assumptions and projections and has not been prepared in conformance with the applicable requirements of Regulation S-X relating to pro forma financial information, and the required pro forma adjustments have not been applied and are not reflected therein. This information is provided for illustrative purposes only and should not be considered in isolation from, or as a substitute for, the historical financial statements of Solstice and Element Solutions. These measures are provided for illustrative purposes and are based on an arithmetic sum of the relevant historical financial measures of Solstice and Element Solutions. Combined Adjusted EBITDA is the arithmetic sum of Solstice's Adjusted Standalone EBITDA and Element Solutions' Pro Forma Adjusted EBITDA, inclusive of expected net synergies. Combined Adjusted EBITDA Margin is inclusive of expected net synergies. These measures do not reflect what the combined company's financial condition or results of operations would have been had the proposed transaction occurred on or prior to the dates indicated. Such illustrative information may differ materially from pro forma information included in SEC filings. Various factors could cause actual future results to differ materially from those currently estimated by management, including, but not limited to, the risks described above and in each of Solstice's and Element Solutions' respective filings with the SEC.

This communication also includes certain financial measures not calculated in accordance with U.S. generally accepted accounting principles ("GAAP"), such as adjusted standalone EBITDA, pro forma adjusted EBITDA, combined adjusted EBITDA, combined adjusted EBITDA margin, combined sales, synergies, integration benefits, free cash flow, net debt and net leverage. Non-GAAP financial measures have limitations as an analytical tool and are not meant to be considered in isolation from, or as a substitute for, the comparable GAAP measures. There are limitations to non-GAAP financial measures because they are not prepared in accordance with GAAP and may not be comparable to similarly titled measures of other companies due to potential differences in methods of calculation and items being excluded. Solstice and Element Solutions caution you not to place undue reliance on these non-GAAP financial measures.

For a definition of Solstice's adjusted standalone EBITDA and Element Solutions' adjusted EBITDA and a reconciliation of adjusted standalone EBITDA and adjusted EBITDA to the most comparable GAAP financial measure for 2025, please see Solstice's Current Report on Form 8-K furnished with the SEC on February 11, 2026 and Element Solutions' Current Report on Form 8-K furnished with the SEC on February 17, 2026 and Element Solutions' 2026 Investor Day presentation at its website at https://www.elementsolutions.com (information included on or accessible through Element Solutions' website is not incorporated by reference into this communication). Element Solutions' pro forma Adjusted EBITDA for fiscal year 2025 is from Element Solutions' 2026 Investor Day presentation and is Element Solutions' Adjusted EBITDA inclusive of a pro forma adjustment of $61 million from the impact of the acquisitions of Micromax and EFC Gases. Combined Adjusted EBITDA and Combined Adjusted EBITDA margin includes expected synergies, net of the costs to achieve.
