Consolidated Variable Interest Entities (VIEs) - As a result of the Delaware Basin JV Acquisition and the EnLink Acquisition, these respective entities are no longer considered VIEs.

As of September 30, 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 liquefied 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.

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.

As of September 30, 2025, the assets and liabilities of our consolidated VIEs were not material.
