ONEOK INC NEW

Consolidated Variable Interest Entities (VIE)s - As a result of the EnLink Acquisition completed on January 31, 2025, EnLink is no longer considered a VIE.

As of March 31, 2025, we consolidated the following VIEs:

MBTC Pipeline -On February 4, 2025, we announced a definitive agreement with MPLX to form the MBTC Pipeline joint venture, which will construct and operate a 24-inch pipeline from our Mont Belvieu, Texas, storage facility to a new liquified petroleum gas export terminal in Texas City, Texas. We own an 80% interest in MBTC Pipeline and we are the operator. MBTC Pipeline is a VIE because the nonmanaging member does not have substantive rights (except in the case of default and other triggering events) to remove the managing member or participating rights over the managing member. As the managing member, we are the primary beneficiary because we control the decisions that most significantly impact MBTC Pipeline.

Delaware Basin JV- We own a 50.1% interest in the Delaware Basin JV, which owns processing facilities located in the Delaware Basin in Texas, and we are the operator. The Delaware Basin JV is a VIE because the nonmanaging member does not have substantive rights to remove the managing member or participating rights over the managing member. As the managing member, we are the primary beneficiary because we control the decisions that most significantly impact the Delaware Basin JV. After June 30, 2025, our joint venture partner has the right to cause the Delaware Basin JV to commence a sale process to sell all of the outstanding interests or assets of the Delaware Basin JV for the best available price. If our joint venture partner exercises this right, we are permitted to purchase their interest at a contractually determined call price.

Ascension- We own a 50% interest in Ascension, which owns an NGL transmission pipeline that connects our Riverside fractionator to the other owner’s refinery. Ascension is a VIE because the nonmanaging member does not have substantive rights (except in the case of default and other triggering events) to remove us as the managing member. They also do not have the ability to participate or block our decisions as the managing member, which makes us the primary beneficiary because we control the decisions that most significantly impact Ascension.
