South Bow's 2025 Report Card: Pipeline Integrity and Growth on the Line

CALGARY, Alberta – February 05, 2026 – South Bow Corporation (TSX & NYSE: SOBO) is set to face intense scrutiny from investors as it prepares to release its fourth-quarter and full-year 2025 financial results on March 5, 2026. The pipeline operator, spun off from TC Energy in late 2024, will host a conference call with senior leadership the following morning to dissect a year marked by significant operational challenges, strategic project milestones, and volatile market conditions.

The upcoming report represents a critical barometer for the company's performance and resilience in its first full year as a standalone entity. Stakeholders will be looking beyond the headline numbers for clarity on the company's ability to manage its cornerstone Keystone Pipeline System, execute on its growth strategy, and navigate a complex financial landscape defined by a pressing need to deleverage.

A Year of Operational Tests and Financial Resilience

South Bow's 2025 was largely defined by an operational incident that tested its crisis management and technical capabilities. In April 2025, an oil spill on the Keystone Pipeline near Fort Ransom, North Dakota, referred to as the Milepost 171 incident, forced a temporary shutdown of the critical artery. The event triggered a corrective action order from the U.S. Pipeline and Hazardous Materials Safety Administration (PHMSA) and initiated a costly remediation process estimated at around $55 million, a sum the company expects to be largely covered by insurance.

While the pipeline's throughput saw a temporary dip, with Q2 2025 volumes averaging approximately 544,000 barrels per day (bbl/d), the system demonstrated its essential nature by maintaining high utilization for most of the year. Throughput recovered to 584,000 bbl/d in the third quarter, and the system averaged 94% of its 620,000 bbl/d capacity in the first half of 2025. This underscores Keystone's vital role in connecting heavy crude from Alberta's oil sands to high-demand U.S. Gulf Coast refining markets.

Financially, the company has shown a mixed but resilient picture. In its third-quarter results reported in November 2025, South Bow posted revenue of $461 million, missing analyst consensus. However, it delivered a significant earnings beat, with adjusted earnings per share (EPS) of $0.47, well above the expected $0.38. This outperformance was driven largely by a one-time $71 million tax recovery and disciplined cost management, which helped offset weaker revenue. The company reaffirmed its full-year 2025 guidance for normalized EBITDA of approximately $1.01 billion and even revised its distributable cash flow projection upward to $700 million, signaling underlying financial stability.

Navigating Shifting Market Headwinds

South Bow's performance is inextricably linked to the broader North American energy landscape, which experienced significant shifts in 2025. The fourth quarter saw a decrease in crude oil prices as global supply began to outpace demand, creating headwinds for the sector. Furthermore, the spread between West Texas Intermediate (WTI) and Western Canadian Select (WCS) crude widened, a dynamic that directly impacts the economics of transporting Canadian heavy oil.

A major structural change was the full operational startup of the Trans Mountain Expansion Project (TMEP) in May 2024. The expansion added significant pipeline capacity out of Western Canada, alleviating long-standing export bottlenecks and giving producers new access to tidewater markets. While this introduced a new competitive element, the continued high utilization of the Keystone system suggests its direct route to the specialized heavy crude refineries on the U.S. Gulf Coast remains a highly valued, premium service. Investors will be keen to hear management's perspective on how these market dynamics influenced fourth-quarter volumes and contracting strategies.

Despite the new capacity from TMEP, the industry consensus is that new, large-scale crude oil pipeline projects are unlikely in the near term, placing a greater emphasis on the reliability and optimization of existing infrastructure like Keystone. This positions South Bow as a critical, long-term player, provided it can maintain its operational integrity.

Investor Focus on Deleveraging and the Blackrod Payoff

Beyond the immediate results, the March 6th conference call will be dominated by discussions of South Bow's future financial health and growth drivers. Two topics stand out: the company's deleveraging plan and the imminent contribution of the Blackrod Connection Project.

Since its inception, South Bow has operated with significant leverage, a key concern for analysts and rating agencies. The company anticipates exiting 2025 with a net debt-to-normalized EBITDA ratio of approximately 4.8 times. Management has laid out a clear path to reduce this to a more sustainable 4.0 times by 2028, and progress toward this goal will be a primary focus of investor questions.

Crucial to this deleveraging strategy is the Blackrod Connection Project. This 25-kilometer natural gas lateral, which recently achieved mechanical completion, is expected to enter commercial service in early 2026. The project is designed to serve a major oil sands facility, and its associated cash flows are projected to begin ramping up in the second half of 2026 and into 2027. This new, stable revenue stream is fundamental to South Bow's ability to pay down debt while supporting its stated quarterly dividend of $0.50 per share.

Analysts and investors will be pressing for a detailed timeline on the Blackrod in-service date and the expected trajectory of its cash flow contributions. The company's 2026 guidance, which projects normalized EBITDA of $1.03 billion and distributable cash flow of $655 million, hinges on the successful and timely execution of this project. The upcoming report will serve as a crucial test of management's credibility and its ability to deliver on these foundational promises to the market.
