Item 5.07 Submission of Matters to Vote of Security Holders.

On September 21, 2023, ONEOK, Inc. (“ONEOK”) held a virtual special meeting of shareholders (the “Special Meeting”) to consider and vote upon proposals to (i) approve the issuance of shares of common stock of ONEOK to the holders of common units representing a limited partner interest in Magellan Midstream Partners, L.P. (“Magellan”) pursuant to the terms of the Agreement and Plan of Merger (the “Merger Agreement”), dated May 14, 2023, by and among ONEOK, Magellan and Otter Merger Sub, LLC, a direct subsidiary of ONEOK (the “Stock Issuance Proposal”) and (ii) approve the adjournment of the Special Meeting, if necessary or appropriate, to solicit additional votes from shareholders if there are not sufficient votes to adopt the Stock Issuance Proposal (the “ONEOK Adjournment Proposal”).

A total of 327,056,111 shares of common stock of ONEOK, or approximately 73% of the voting power of the shares entitled to vote at the Special Meeting, were present in person or represented by proxy, constituting a quorum for the transaction of business. The final voting results are set forth below.

Each of the proposals is described in greater detail in the joint proxy statement/prospectus, dated July 24, 2023, as supplemented (the “joint proxy statement/prospectus”), and first mailed to ONEOK’s shareholders on or about July 25, 2023.

ONEOK’s shareholders approved the Stock Issuance Proposal by the following votes:

Because the ONEOK shareholders approved the Stock Issuance Proposal, the vote on the ONEOK Adjournment Proposal was not called.

Consummation of the transactions contemplated by the Merger Agreement are subject to the satisfaction of certain customary closing conditions, all as set forth in the Merger Agreement and discussed in detail in the joint proxy statement/prospectus, which is available on the U.S. Securities and Exchange Commission’s website at www.sec.gov. The foregoing description is qualified in its entirety by reference to the full text of the Merger Agreement, which is attached as Annex A to the joint proxy statement/prospectus. Assuming the satisfaction of such closing conditions, the Company expects the closing of the transactions contemplated by the Merger Agreement to occur on or about September 25, 2023.
