Company Description
South Bow Corporation (SOBO) is an energy infrastructure company in the oil and gas midstream sector. According to company disclosures, South Bow safely operates approximately 4,900 kilometres (3,045 miles) of crude oil pipeline infrastructure. Its systems connect Alberta crude oil supplies to U.S. refining markets in Illinois, Oklahoma, and the U.S. Gulf Coast. The company focuses on the safe and reliable transportation of crude oil to some of North America's highest demand markets and trades on both the Toronto Stock Exchange (TSX) and the New York Stock Exchange (NYSE) under the symbol SOBO.
South Bow is based in Calgary, Alberta, and is the spinoff company of TC Energy. The company states that Oct. 1, 2024 marked its first day as a standalone entity following this spinoff. As a result, South Bow has been implementing its own systems and processes, including a new enterprise resource planning system and a new supervisory control and data acquisition (SCADA) system, to fully establish itself as an independent midstream operator.
Business model and segments
According to South Bow’s public communications, the company is engaged in constructing and operating pipeline systems that safely transport liquids such as crude oil across Canadian provinces, U.S. states, and the U.S. Gulf Coast. The business is organized into three reportable segments: Keystone Pipeline System, Marketing, and Intra-Alberta & Other. The Keystone Pipeline System segment is identified as the primary contributor to revenue. South Bow’s financial results highlight normalized earnings before interest, income taxes, depreciation, and amortization (normalized EBITDA) by segment, reflecting the importance of the Keystone Pipeline System, as well as contributions and, at times, losses from the Marketing segment and additional contributions from Intra-Alberta & Other.
The Keystone Pipeline System is central to South Bow’s operations. Company reports describe throughput volumes on the Keystone Pipeline and on the U.S. Gulf Coast segment of the Keystone Pipeline System, as well as a System Operating Factor (SOF) that measures the company’s ability to deliver crude oil at the planned maximum rate. Marketlink throughput, which comprises barrels originating in Hardisty, Alberta and Cushing, Oklahoma for delivery to the U.S. Gulf Coast, is also disclosed as part of operational performance.
Pipeline network and market connectivity
South Bow’s crude oil pipeline infrastructure connects supply from the Western Canadian Sedimentary Basin to multiple U.S. refining markets. The company notes that its system links Alberta crude oil supplies to refineries in Illinois, Oklahoma, and the U.S. Gulf Coast. South Bow refers to its market position as providing connections to North America’s highest demand markets for crude oil, reflecting the strategic location of its pipeline assets relative to key refining hubs.
Operational metrics disclosed in quarterly updates include average daily throughput on the Keystone Pipeline, throughput on the U.S. Gulf Coast segment, Marketlink throughput, and SOF percentages. These measures provide insight into how intensively the pipeline network is being used and how reliably it is operating over time.
Spinoff from TC Energy and corporate development
South Bow describes itself as the spinoff company of TC Energy, with Oct. 1, 2024 identified as the date it began operating as a standalone entity. In its first full year as an independent company, South Bow has focused on establishing separate corporate systems and exiting a Transition Services Agreement with TC Energy. Reported milestones include the implementation of a new enterprise resource planning system and the planned transition to a new SCADA system, which is described as the final significant item in exiting the Transition Services Agreement.
The company has also undertaken capital projects within its strategic corridor. South Bow reports progress on the Blackrod Connection Project, including construction of crude oil and natural gas pipeline segments and related terminal facilities. The project includes a 25-kilometre natural gas lateral and a 150,000-barrel crude oil storage tank. South Bow has indicated that the Blackrod Connection Project is expected to be placed into service in early 2026, with associated cash flows anticipated to increase over subsequent periods, as described in its outlook and guidance discussions.
Safety, integrity, and regulatory oversight
Safety and system integrity are recurring themes in South Bow’s disclosures. The company highlights safety and operational performance as part of its quarterly results, referencing SOF, throughput, and project execution. South Bow describes an extensive integrity program that continuously incorporates new learnings and technologies to support the long-term safety and reliability of its assets.
In 2025, South Bow reported an oil release at Milepost 171 (MP-171) of the Keystone Pipeline near Fort Ransom, North Dakota. In response, the company shut down the pipeline, isolated the affected segment, and initiated emergency response procedures, including around-the-clock air and environmental monitoring. South Bow reports that it repaired and replaced the impacted pipe, recovered substantially most of the estimated released volume, and completed cleanup and reclamation of the incident site. The company notes that the Pipeline and Hazardous Materials Safety Administration (PHMSA) issued a Corrective Action Order requiring pressure restrictions on specific segments and a root cause failure analysis.
According to South Bow, mechanical and metallurgical analysis determined that the failure was caused by a fatigue crack originating along the pipe’s long-seam weld, with both the pipe and welds conforming to industry standards for design, materials, and mechanical properties. The company has undertaken multiple in-line inspection runs and integrity digs, reporting preliminary results that indicate no injurious issues. South Bow states that it is finalizing a remedial work plan for regulatory approval and that findings from the root cause analysis and inspections will be incorporated into its integrity programs.
Financial framework and capital allocation
South Bow reports its financial performance using both GAAP and non-GAAP measures, including normalized EBITDA, normalized net income, distributable cash flow, and net debt. The company discloses that a significant portion of its normalized EBITDA is secured through committed arrangements, which it characterizes as carrying minimal commodity price or volumetric risk. South Bow also provides guidance for normalized EBITDA, distributable cash flow, capital expenditures, and effective tax rates, along with explanations of changes in its definitions of certain non-GAAP measures.
The company’s capital expenditures are categorized into growth and maintenance spending. Maintenance capital expenditures are described as generally recoverable through South Bow’s tolling arrangements. South Bow has communicated expectations for one-time separation costs associated with the spinoff from TC Energy and has outlined its approach to leverage, including a net debt-to-normalized EBITDA ratio target range and expectations around that ratio as it invests in projects such as the Blackrod Connection Project.
South Bow’s stated capital allocation priorities include paying a base dividend, strengthening its investment-grade financial position, and using existing infrastructure within its strategic corridor to offer competitive connections and enhanced optionality for customers. The company has declared regular quarterly dividends, designated as eligible dividends for Canadian income tax purposes, and provides information on dividend amounts per share in its quarterly releases.
Regulatory filings and governance
As a foreign private issuer, South Bow files reports with the U.S. Securities and Exchange Commission on Form 40-F and Form 6-K. Recent 6-K filings reference press releases, management’s discussion and analysis, interim financial statements, and certifications under the Sarbanes-Oxley Act. The company also files notices of reliance for South Bow USA Infrastructure Holdings LLC and South Bow Canadian Infrastructure Holdings Ltd., which relate to certain outstanding notes and exchange offers.
South Bow’s annual general meeting materials and related disclosures indicate that shareholders vote on the appointment of directors, the appointment of auditors, and the company’s approach to executive compensation. Resolutions at the annual general meeting have included the election of 11 board members and the appointment of KPMG LLP as auditors.
Market context and outlook as described by the company
In its outlook sections, South Bow comments on crude oil pipeline capacity and supply in the Western Canadian Sedimentary Basin, noting that pipeline egress capacity continues to exceed crude oil supply. The company states that demand for uncommitted capacity on the Keystone Pipeline is expected to remain low in the near term. South Bow also references economic and geopolitical uncertainty, including changing global trade policies and tariffs, as factors contributing to volatility in commodity prices and pricing differentials.
Within this context, South Bow’s guidance emphasizes its highly contracted assets and structural demand for services. The company has reaffirmed normalized EBITDA guidance ranges for 2025 and provided an initial outlook for 2026, including a projection for normalized EBITDA and the proportion expected to be secured through committed arrangements. South Bow also discusses expected performance of its Marketing segment and the impact of U.S. tax legislation changes and tax optimization efforts on distributable cash flow.
