Business acquisition description       On October 9, 2026, through a wholly-owned subsidiary, we acquired from Salt Creek Midstream (Salt Creek) all of the membership interests of FS Crude Holdings, LLC (FS Crude) for total cash consideration of approximately $892 million (US$625 million) (the Salt Creek Crude Acquisition). FS Crude owns 100% of the Orla and Wink North systems and 50% of the Delaware Crossing system, which combined include approximately 500 miles of crude oil gathering infrastructure located in the Delaware Basin. The Salt Creek Crude Acquisition is expected to strengthen our crude oil value chain in the Permian Basin by providing a strategic connection between crude oil production and our Gray Oak and Cactus II Pipeline systems, as well as our Enbridge Ingleside Energy Center.
