South Bow Corporation Common Shares (SOBO) fair value

ACCE thesis

South Bow owns and operates the Keystone pipeline system and Canadian crude and natural gas liquids infrastructure, earning mostly fee-based and contracted cash flows rather than commodity price exposure. Its moat is physical: a large, hard-to-replicate network of long-haul pipe moving Western Canadian barrels to US Gulf and Midwest markets, with contracts that tend to be long-dated and take-or-pay. Revenue growth of 4.2% is modest, but a 43.8% operating margin and 17.3% return on equity show how much of each dollar the system keeps. At 15.3 times trailing earnings and 17.5 times forward, the stock is priced for steady throughput rather than expansion, so the question for a deeper look is whether contracted volumes and Keystone's utilization hold up through a cycle, and how much of the earnings base depends on any single customer or contract roll.
