New Credit Agreement

On February 14, 2025 (the “Closing Date”), ONEOK, Inc. (“ONEOK” or the “Company”), as borrower, entered into a second amended and restated credit agreement (the “New Credit Agreement”) with Citibank, N.A. (“Citibank”), as administrative agent, a swing line lender, a letter of credit issuer and a lender, and each of the other lenders, swing line lenders and letter of credit issuers party thereto (the “Lenders”), pursuant to which the Lenders agreed to provide loans and other extensions of credit to ONEOK. The New Credit Agreement amends and restates the Company’s existing revolving credit agreement, dated as of June 10, 2022 (as amended by that certain First Amendment to Credit Agreement, dated as of May 26, 2023, the “Existing Credit Agreement”), by and among the Company, Citibank and the lenders party thereto. The terms of the New Credit Agreement (as discussed in more detail below) are substantially similar to the Existing Credit Agreement, except for modifications to (i) increase the size of the revolving unsecured credit facility from $2.5 billion to $3.5 billion and (ii) extend the maturity date from June 2028 to February 2030.

Pursuant to the New Credit Agreement, the Lenders have provided to ONEOK a $3.5 billion revolving unsecured credit facility, which includes a $100 million letter of credit subfacility and a $200 million swing line subfacility. The revolving loans will bear interest at a rate per annum based upon, at the Company’s option, the Term SOFR rate or the alternative base rate, plus, in each case, a ratings-based margin.

Under the terms of the New Credit Agreement, ONEOK will be able to request an increase in the commitments of up to an additional $1.0 billion upon satisfaction of customary conditions, including receipt of commitments from either new lenders or increased commitments from existing lenders.

Proceeds from borrowings under the New Credit Agreement may be used to provide liquidity for working capital, capital expenditures, acquisitions, mergers, issuance of letters of credit and for other general corporate purposes.

The New Credit Agreement contains various conditions to borrowing, certain affirmative and negative covenants, which ONEOK considers to be customary for facilities of this type, and a covenant to maintain a net leverage ratio not to exceed 5.00:1.00, stepping up to 5.50:1.00 for the two fiscal quarters following the consummation of an acquisition with a purchase price in excess of $25 million. The New Credit Agreement also contains various events of default, which ONEOK considers to be customary for facilities of this type, the occurrence of which could result in a termination of the Lenders’ commitments and the acceleration of all of the Company’s obligations thereunder.

The New Credit Agreement will mature in five years after the Closing Date. ONEOK will be able extend the maturity date, subject to the lenders’ consent, by one year up to two times.

The foregoing description of the New Credit Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the New Credit Agreement, a copy of which has been filed as Exhibit 10.1 to this Current Report on Form 8-K and which is incorporated by reference herein.

Under the New Credit Agreement Guaranty, each Guarantor will be jointly and severally liable for ONEOK’s obligations under the New Credit Agreement. Any such liabilities will be senior unsecured obligations of the Guarantors and will rank equally in right of payment with all existing and future senior unsecured indebtedness of the Guarantors.
