ONEOK INC NEW

Current Maturities -At Sept. 30, 2024, our current maturities of long-term debt consist of the following:

Debt Issuances - In September 2024, we completed an underwritten public offering of $7.0 billion senior unsecured notes consisting of $1.25 billion,4.25% senior notes due 2027; $600 million,4.4% senior notes due 2029; $1.25 billion,4.75% senior notes due 2031; $1.6 billion,5.05% senior notes due 2034; $1.5 billion,5.7% senior notes due 2054; and $800 million,5.85% senior notes due 2064. The net proceeds, after deducting underwriting discounts, commissions and offering expenses, were $6.9 billion. We intend to use the net proceeds from this offering to fund the EnLink Controlling Interest Acquisition and the Medallion Acquisition, purchase additional interests in a Medallion joint venture owned by a separate third party and to pay fees and expenses related to the acquisitions. We intend to use any remaining net proceeds for general corporate purposes, which may include the repayment of outstanding indebtedness, including the repurchase or redemption of existing notes. Cash held as of Sept. 30, 2024, to fund the acquisitions is classified as a long-term asset within the Consolidated Balance Sheet due to its designation for use in conjunction with these acquisitions.

Subsequent event - In October 2024, we used a portion of the net proceeds to fund the EnLink Controlling Interest Acquisition upon closing.

Debt Repayments- In September 2024, we repaid the remaining $484 million of our $500 million,2.75% senior notes at maturity with cash on hand.

Commercial Paper Program - At Sept. 30, 2024, and Dec. 31, 2023, we hadno commercial paper outstanding.

$2.5 Billion Credit Agreement- Our $2.5 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 $2.5 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 $2.5 Billion Credit Agreement allows inclusion of the trailing 12 months of consolidated adjusted EBITDA of any acquired business. In May 2024, we entered into an amendment to our $2.5 Billion Credit Agreement that extended the maturity date byone year, from June 2027 to June 2028. All other terms and conditions of our $2.5 Billion Credit Agreement remain unchanged. In June 2024, we completed the acquisition of a system of NGL pipelines, which allowed us to elect an acquisition adjustment period under our $2.5 Billion Credit Agreement and, as a result, increased our leverage ratio covenant to 5.5 to 1. In October 2024, we completed the EnLink Controlling Interest Acquisition, which effectively extended our acquisition adjustment period until the quarter ended June 30, 2025, after which it will decrease to 5.0 to 1. As of Sept. 30, 2024, we hadno outstanding borrowings, our ratio of consolidated indebtedness to adjusted EBITDA was 3.7 to 1, and we were in compliance with all covenants under our $2.5 Billion Credit Agreement.
