Item 1.01

Entry into a Material Definitive Agreement.

On May 12, 2026, Cabot Corporation (the “Company”) entered into a $1.3 billion unsecured revolving credit agreement (the “Credit Agreement”) with a syndicate of lenders arranged by JPMorgan Chase Bank, N.A. and JPMorgan SE, as Administrative Agents, JPMorgan Chase Bank, N.A., Citibank, N.A., U.S. Bank, National Association and PNC Capital Markets LLC, as Joint Lead Bookrunners and Joint Lead Arrangers, Bank of America, N.A., ING Bank N.V. Dublin Branch and Banco Bilbao Vizcaya Argentaria, S.A. New York Branch, as Joint Lead Arrangers and Co-Documentation Agents, and Citibank, N.A., as Syndication Agent.

Borrowings under the Credit Agreement may be made in multiple currencies and will be used for general corporate purposes. The facility matures on May 12, 2031. At the Company’s election, loans will bear interest at the Term Benchmark or RFR Spread, as applicable, rate plus an applicable margin of between 0.68% and 1.20%, depending on the Company’s credit ratings. The Credit Agreement requires the Company to comply on a quarterly basis with a leverage test requiring net debt (with the ability to offset such debt by the lesser of (i) unrestricted cash and cash equivalents and (ii) $200 million) not to exceed consolidated EBITDA for the four quarters then ending by more than 3.75 to 1.00. Following the consummation of any material acquisition, the maximum leverage ratio shall be increased to 4.25 to 1.00, as of the end of the fiscal quarter in which such material acquisition occurs and the three fiscal quarters immediately thereafter. Consistent with the Company’s former $1 billion revolving credit agreement, the Credit Agreement also includes customary negative covenants, representations and warranties, affirmative covenants and events of default.

This description is a summary and is qualified in its entirety by reference to the Credit Agreement, which is filed as Exhibit 10.1 to this Current Report on Form 8-K.
