Enbridge Buys Tallgrass Energy Assets for $2.55 Billion

Enbridge is significantly expanding its footprint in the U.S. Rocky Mountains through a definitive agreement to acquire a substantial portfolio of crude oil infrastructure from Tallgrass Energy. The transaction, valued at $2.55 billion, will integrate key gathering, transportation, storage, and terminal assets, enhancing Enbridge's liquids pipeline network and providing direct access to vital production basins.

This strategic move grants Enbridge new conduits for crude oil originating from the Powder River Basin and the Denver-Julesburg Basin. These newly accessible resources will be connected to the critical Cushing, Oklahoma, crude oil trading hub, a cornerstone of North American energy logistics. The acquisition is expected to close in the latter half of 2026, subject to customary closing conditions.

Central to the deal is Enbridge's acquisition of a 75% stake in the Pony Express Pipeline. This 1,050-mile system, stretching from Guernsey, Wyoming, and various Colorado locations to Cushing, boasts an average annual capacity of approximately 460,000 barrels per day. Furthermore, Pony Express offers direct connections to around 500,000 barrels per day of refining capacity, underscoring its market significance.

The transaction also includes a 51% interest in the Powder River Gateway system, comprising the Iron Horse and Powder River Express pipelines. These assets, with a combined capacity of roughly 240,000 barrels per day, serve as crucial links from the Powder River Basin to the Pony Express system. Complementing these pipelines are approximately 8.4 million barrels of storage capacity across nine terminals, including a significant non-operating interest in the Deeprock Crude Terminal in Cushing. The deal also encompasses Stanchion Energy’s crude marketing business.

Looking ahead, Enbridge will assume responsibility for the $300 million PXP2 expansion project on the Pony Express system. This initiative is projected to boost the pipeline's capacity to 515,000 barrels per day and is slated for service by late 2027. This expansion aligns with Enbridge's strategy to capitalize on growing production trends in the region and further solidifies its market position.

The acquired assets are highly complementary to Enbridge's existing Express-Platte network, which currently moves crude from Alberta, Canada, to Illinois. The Pony Express system is notably well-contracted through the end of the decade, primarily with investment-grade counterparties, signaling a stable and predictable revenue stream. Enbridge anticipates this acquisition will generate substantial free cash flow, unlock further growth avenues, and realize operational synergies across its extensive liquids pipeline operations.

This acquisition represents an estimated forward enterprise value to EBITDA multiple of 10x to 11x, reflecting a disciplined approach to capital allocation within the energy infrastructure sector. The deal's structure and valuation are consistent with recent transactions in the midstream space, where strategic consolidation continues to drive efficiency and market access. As operator of Pony Express, Enbridge, through its Executive Vice President and President of Liquids Pipelines, Colin Gruending, expressed confidence in leveraging its operational expertise to ensure safe and reliable service for customers.
