Solstice Advanced Materials Inc. (the “Company”), a wholly-owned subsidiary of Honeywell International Inc. (“Honeywell”), previously filed with the U.S. Securities and Exchange Commission (the “SEC”) a Registration Statement on Form 10, initially filed on August 21, 2025 and amended on September 30, 2025 (as amended, the “Form 10”), in connection with the anticipated spin-off of Honeywell’s Advanced Materials business into an independent, publicly traded company (the “Spin-Off”). On September 30, 2025, the Form 10 was declared effective by the SEC. The Form 10 includes a preliminary information statement that describes the Spin-Off and provides important information regarding the Company’s business and management.

The final information statement, dated October 17, 2025 (the “Information Statement”), is attached hereto as Exhibit 99.1. Honeywell has made the Information Statement publicly available on Honeywell’s website at https://investor.honeywell.com under the “About Our Spin-Offs” tab and expects to begin mailing to its stockholders a Notice of Internet Availability of Information Statement Materials, the form of which is attached hereto as Exhibit 99.2, on or around October 17, 2025.

As announced by Honeywell on October 16, 2025, Honeywell will distribute all of the issued and outstanding shares of Company common stock to the holders of record of Honeywell common stock at 12:01 a.m. (New York City time) on October 30, 2025 (the “Distribution Date”). On the Distribution Date, holders of record of Honeywell common stock will receive one share of Company common stock for every four shares of Honeywell common stock they hold as of the close of business on October 17, 2025, the record date for the distribution.

Completion of the Spin-Off is conditioned upon the satisfaction or waiver of certain conditions, as set forth in the form of Separation and Distribution Agreement filed with the SEC as part of the Form 10.

Cautionary Statement About Forward-Looking Statements

Certain statements in this Current Report on Form 8-K are forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934. Forward-looking statements are those that address activities, events, or developments that management intends, expects, projects, believes, or anticipates will or may occur in the future. They are based on management’s assumptions and assessments in light of past experience and trends, current economic and industry conditions, expected future developments, and other relevant factors, many of which are difficult to predict and outside of the

Company’s control. They are not guarantees of future performance, and actual results, developments and business decisions may differ significantly from those envisaged by the Company’s forward-looking statements. The Company does not undertake to update or revise any of the Company’s forward-looking statements, except as required by applicable securities law. The Company’s forward-looking statements are also subject to material risks and uncertainties, including ongoing macroeconomic and geopolitical risks, such as changes in or application of trade and tax laws and policies, including the impacts of tariffs and other trade barriers and restrictions, lower GDP growth or recession in the U.S. or globally, supply chain disruptions, capital markets volatility, inflation, and certain regional conflicts, that can affect the Company’s performance in both the near- and long-term. In addition, no assurance can be given that any plan, initiative, projection, goal, commitment, expectation, or prospect set forth in this Current Report on Form 8-K can or will be achieved. Some of the important factors that could cause the Company’s actual results to differ materially from those projected in any such forward-looking statements include, but are not limited to: (i) the ability of Honeywell to effect the Spin-Off described above and to meet the conditions related thereto; (ii) the possibility that the Spin-Off will not be completed within the anticipated time period or at all; (iii) the possibility that the Spin-Off will not achieve its intended benefits; (iv) the possibility of disruption, including disputes, litigation or unanticipated costs, in connection with the Spin-Off; (v) the uncertainty of the expected financial performance of the Company following completion of the Spin-Off; (vi) the ability to achieve anticipated capital structures in connection with the Spin-Off, including the future availability of credit and factors that may affect such availability; (vii) the ability to achieve anticipated tax treatments in connection with the Spin-Off and future, if any, divestitures, mergers, acquisitions and other portfolio changes and the impact of changes in relevant tax and other laws; and (viii) the failure to realize expected benefits and effectively manage and achieve anticipated synergies and operational efficiencies in connection with the Spin-Off and future, if any, divestitures, mergers, acquisitions, and other portfolio management, productivity and infrastructure actions. These forward-looking statements should be considered in light of the information included in this Current Report on Form 8-K, the Form 10 and the Company’s other filings with the SEC. Any forward-looking plans described herein are not final and may be modified or abandoned at any time.
