Commercial Paper Program - At March 31, 2025, we had $200 million of commercial paper outstanding, bearing a weighted-average interest rate of 4.64%. At December 31, 2024, we had no commercial paper outstanding.

$3.5 Billion Credit Agreement - In February 2025, we amended and restated our $2.5 Billion Credit Agreement to increase the size to $3.5 billion, extend the term to February 2030 and make other nonmaterial modifications. Our $3.5 Billion Credit Agreement is a revolving credit facility and contains certain customary conditions for borrowing, as well as customary financial, affirmative and negative covenants. Among other things, these covenants include maintaining a ratio of consolidated net indebtedness to adjusted EBITDA (EBITDA, as defined in our $3.5 Billion Credit Agreement, adjusted for all noncash charges and increased for projected EBITDA from certain lender-approved capital expansion projects). In addition, adjusted EBITDA as defined in our $3.5 Billion Credit Agreement allows inclusion of the trailing 12 months of consolidated adjusted EBITDA of the acquired business. In February 2025, we announced definitive agreements to form joint ventures with MPLX, which allowed us to effectively extend the acquisition adjustment period under our $3.5 Billion Credit Agreement and, as a result, our leverage ratio covenant of 5.5 to 1 was extended through the quarter ending September 30, 2025, after which it will decrease to 5.0 to 1. As of March 31, 2025, we had no outstanding borrowings, our ratio of consolidated indebtedness to adjusted EBITDA was 4.1 to 1, and we were in compliance with all covenants under our $3.5 Billion Credit Agreement.
Debt Repayments - In March 2025, we repaid our $250 million, 3.2% senior notes at maturity with cash on hand.

EnLink Acquisition - Upon the closing of the EnLink Acquisition on January 31, 2025, we terminated the EnLink Revolving Credit Facility. We also effectively terminated the agreement to provide revolving unsecured loans to EnLink through a promissory note. For further details on the EnLink Revolving Credit Facility and the promissory note, see Note H of the Notes to Consolidated Financial Statements in our Annual Report.

Debt Guarantees - At the completion of the EnLink Acquisition on January 31, 2025, ONEOK assumed the outstanding debt of EnLink and EnLink Partners (the “Assumed Debt”). EnLink and EnLink Partners were released from all debt obligations and each entity provided a guarantee for our and ONEOK Partners’ indebtedness to the holders of each series of outstanding securities, including for the Assumed Debt.

ONEOK, ONEOK Partners, the Intermediate Partnership, Magellan, EnLink and EnLink Partners have cross guarantees in place for ONEOK’s and ONEOK Partners’ indebtedness. For further details on our indebtedness, see Note H of the Notes to Consolidated Financial Statements in our Annual Report.
