Long-Term Debt

Senior Revolving Credit Facility—Our $3,750 million senior unsecured revolving credit facility (the “Senior Revolving Credit Facility”), which expires in July 2029, may be used for dollar and euro denominated borrowings. The facility also supports our commercial paper program, has a $200 million sub-limit for dollar and euro denominated letters of credit and a $1,000 million uncommitted accordion feature. Borrowings under the facility bear interest at either a base rate, secured overnight financing rate or EURIBOR rate, plus an applicable margin. Additional fees are incurred for the average daily unused commitments. As of September 30, 2025, we hadno borrowings or letters of credit outstanding and $3,750 million of unused availability under this facility.

In September 2025, we amended the Senior Revolving Credit Facility primarily to increase the Maximum Leverage Ratio (as defined in the Credit Agreement) through 2027 unless we elect to terminate such provisions sooner. The Maximum Leverage Ratio is as follows:

•4.25 to 1.00 for the fiscal quarters ending September 30, 2025 and December 31, 2025;

•4.50 to 1.00 for the fiscal quarters ending March 31, 2026 through June 30, 2027;

•4.25 to 1.00 for the fiscal quarter ending September 30, 2027;

•4.00 to 1.00 for the fiscal quarter ending December 31, 2027; and

•3.50 to 1.00 thereafter.

Included in the amendment are certain limitations, including restrictions on dividend increases, if our leverage ratio is greater than or equal to 4.00 to 1.00, and share repurchases except to offset dilution.

Guaranteed Notes due 2035—In May 2025, LYB International Finance III, LLC (“LYB Finance III”), a wholly owned finance subsidiary of LyondellBasell Industries N.V., issued $500 million of 6.150% guaranteed notes due 2035 (the “2035 Notes”) at a discounted price of 99.7%. Net proceeds after deducting original issuance discounts, underwriting fees and offering expenses totaled $494 million. Net proceeds from the sale of the notes were used for general corporate purposes, including the repayment of our 2025 Notes.

These unsecured notes, which are fully and unconditionally guaranteed by LyondellBasell Industries N.V., rank equally in right of payment to all of LYB Finance III’s and LyondellBasell Industries N.V.’s existing and future senior unsecured indebtedness and will rank senior in right of payment to any future subordinated indebtedness that LYB Finance III or LyondellBasell Industries N.V. incurs. There are no significant restrictions that would impede LyondellBasell Industries N.V., as guarantor, from obtaining funds by dividend or loan from its subsidiaries. The indenture governing these notes contains limited covenants, including those restricting our ability, and the ability of our subsidiaries, to incur indebtedness secured by significant property or by capital stock of subsidiaries that own significant property, enter into certain sale and lease-back transactions with respect to any significant property or enter into consolidations, mergers or sales of all or substantially all of our assets.

The 2035 Notes may be redeemed at any time in whole, or from time to time in part, prior to the scheduled maturity date, at a redemption price equal to the greater of (i) the sum of the present values of the remaining scheduled payments of principal and interest (discounted at the treasury rate plus the applicable basis points) less interest accrued on the notes to be redeemed, and (ii)100% of the principal amount of the notes redeemed; plus, in either case, accrued and unpaid interest thereon to, but excluding, the redemption date.

The 2035 Notes may also be redeemed at any time, on or after the date that is three months prior to the scheduled maturity date of the notes at a redemption price equal to 100% of the principal amount of the notes to be redeemed plus accrued and unpaid interest thereon to, but excluding, the redemption date. The notes are also redeemable upon certain tax events.

Guaranteed Notes due 2025—In October 2025, we repaid the outstanding principal on our 1.25% guaranteed notes due 2025 of $492 million.

U.S. Receivables Facility—Our U.S. Receivables Facility has a purchase limit of $900 million in addition to a $300 million uncommitted accordion feature. In May 2025, we extended the term of the facility to June 2026. This facility provides liquidity through the sale or contribution of trade receivables by certain of our U.S. subsidiaries to a wholly owned, bankruptcy-remote subsidiary on an ongoing basis and without recourse. We pay variable interest rates on our secured borrowings. Additional fees are incurred for the average daily unused commitments. This facility also provides for the issuance of letters of credit up to $200 million. As of September 30, 2025, we hadno borrowings or letters of credit outstanding and $900 million unused availability under this facility.
