1.01 Entry into a Material Definitive Agreement

On November 23, 2021, LyondellBasell Industries N.V. (the “Company”) and LYB Americas Finance Company LLC, a wholly owned subsidiary of the Company, as Borrowers, the Lenders from time to time party thereto, Citibank, N.A., as Administrative Agent, Wells Fargo Bank, National Association as Syndication Agent and the other parties thereto, entered into an Second Amended and Restated Credit Agreement (the “Amended and Restated Credit Agreement”). The Amended and Restated Credit Agreement provides for a $3.25 billion senior unsecured revolving credit facility that matures on November 23, 2026 and allows for euro and dollar denominated letters of credit and loans.

The Amended and Restated Credit Agreement is maintained for general corporate purposes, including the repayment of indebtedness. The Amended and Restated Credit Agreement amends and restates the previously reported $2.5 billion five-year credit agreement dated as of June 5, 2014 (as amended from time to time, the “Prior Agreement”). Amounts borrowed under the Amended and Restated Credit Agreement are required to be repaid no later than November 23, 2026 unless such date is extended pursuant to the terms of the Amended and Restated Credit Agreement.

The Amended and Restated Credit Agreement contains customary representations and warranties of each of the Company and LYB Americas Finance Company LLC. The Amended and Restated Credit Agreement requires the Company to maintain a maximum consolidated leverage ratio and contains certain restrictive covenants regarding additional indebtedness, including secured and subsidiary indebtedness, and mergers and sales of assets. The minimum liquidity requirements for dividends and share repurchases contained in the Prior Agreement were removed. The Amended and Restated Credit Agreement includes provisions permitting the Company, in consultation with one or more lenders selected by the Company, to establish key performance indicators (“KPIs”) with respect to certain environmental, social and governance targets of the Company and its subsidiaries and upon the effectiveness of any such amendment, the KPIs will be used, together with the pricing grid, to determine pricing under the Amended and Restated Credit Agreement.

The Amended and Restated Credit Agreement contains customary events of default, including nonpayment of principal when due, nonpayment of interest or other amounts after a customary grace period, violation of covenants (subject, in the case of certain of such covenants, to a thirty day grace period), incorrectness of representations and warranties in any material respect, cross acceleration to terms of material indebtedness and cross payment default, bankruptcy or other insolvency events of the Company or its material subsidiaries (with a customary grace period for involuntary events), material monetary judgments, ERISA events, actual or asserted invalidity of loan documents and changes of control.

A copy of the Amended and Restated Credit Agreement is included in this Form 8-K as Exhibit 10.1 and incorporated herein by reference. The summary description of the Amended and Restated Credit Agreement in this report is qualified in its entirety by reference to Exhibit 10.1.
