Item 1.01. Entry into a Material Definitive Agreement.

On December 29, 2025, Huntsman International LLC ("Huntsman International") entered into Master Amendment No. 13 to the U.S. Receivables Loan Agreement and Transaction Documents (the "U.S. A/R Program Amendment 13"), among Huntsman International, Huntsman Receivables Finance II LLC, VANTICO GROUP S.à r.1., as master servicer, The Toronto-Dominion Bank ("TD"), as successor administrative agent and successor collateral agent, and the other financial institutions party thereto.

The U.S. A/R Program Amendment 13, among other things, replaces PNC Bank, National Association with TD as administrative agent and collateral agent, among other responsibilities, increases the lender commitments to $180 million, extends the maturity date to December 29, 2028, and makes certain other amendments to the existing U.S. accounts receivable securitization program.

The parties had previously entered into Master Amendment No. 12 to the U.S. Receivables Loan Agreement dated December 10, 2025 (the "U.S. A/R Program Amendment 12") pursuant to which TD was designated as an issuing bank.

The foregoing does not constitute a complete summary of the terms of the U.S. A/R Program Amendment 12 or the U.S. A/R Program Amendment 13. The description of the terms of the U.S. A/R Program Amendment 13 is qualified in its entirety by reference to such agreement, which is attached hereto as Exhibit 10.1 and incorporated herein by reference. The Company deems the U.S. A/R Program Amendment 12 to be an immaterial amendment and intends to file the amendment with its upcoming Annual Report on Form 10-K.
