        <footnote id="F1">On October 30, 2025, Honeywell International Inc. (&quot;Honeywell&quot;) disposed of all 158,727,456 issued and outstanding shares of common stock, par value $0.01 per share (the &quot;SOLS Common Stock&quot;), of Solstice Advanced Materials Inc., a Delaware corporation (&quot;SOLS&quot;), by distributing a pro rata dividend to Honeywell shareowners of one share of SOLS Common Stock for every four shares of Honeywell Common Stock, par value $1.00 per share, held by each holder of record as of the close of business on October 17, 2025, to effect the previously announced spin-off of SOLS from Honeywell.</footnote>
        <footnote id="F2">On September 30, 2025, Honeywell reported that it owned 158,724,140 shares of SOLS Common Stock, which at the time constituted all the issued and outstanding shares of SOLS Common Stock. Pursuant to an amended and restated certificate of incorporation of SOLS filed with the Secretary of State of the State of Delaware on October 24, 2025, the 158,724,140 shares of SOLS Common Stock were automatically converted into an aggregate of 158,727,456 shares of SOLS Common Stock (the &quot;Recapitalization&quot;).  The Recapitalization was exempt pursuant to Rules 16a-9 and 16b-7 under the Exchange Act and did not result in a change in the pecuniary interest of Honeywell in SOLS.</footnote>
