South Bow Corporation: South Bow Reports Third-quarter 2025 Results, Provides 2026 Outlook, and Declares Dividend

CALGARY, Alberta, Nov. 13, 2025 (GLOBE NEWSWIRE) -- South Bow Corp. (TSX & NYSE: SOBO) (South Bow or the Company) reports its third-quarter 2025 financial and operational results and provides its 2026 outlook. Unless otherwise noted, all financial figures in this news release are in U.S. dollars.

Highlights

Safety and operational performance

• Recorded average throughput of approximately 584,000 barrels per day (bbl/d) on the Keystone Pipeline in the third quarter of 2025, and approximately 703,000 bbl/d on the U.S. Gulf Coast segment of the Keystone Pipeline System.
  • Throughput on the Keystone Pipeline and the U.S. Gulf Coast segment of the Keystone Pipeline System averaged approximately 580,000 bbl/d and approximately 730,000 bbl/d, respectively, during the first nine months of 2025.
• Achieved mechanical completion for the Blackrod Connection Project and placed the 25-km natural gas lateral into commercial service. Final facility activities are currently underway, and the project remains on schedule to be placed into service in early 2026. Associated cash flows are expected to increase throughout the second half of 2026 and into 2027.
• Continued to advance remedial actions relating to the incident that occurred at Milepost 171 (MP-171) of the Keystone Pipeline, including completing six in-line inspections and 37 integrity digs to date. See "Milepost 171 incident" of this news release for additional details.

Financial performance

• Delivered stable financial results in the third quarter of 2025 due to the Company's strong commercial underpinnings.
  • Generated revenue of $461 million and net income of $93 million ($0.45/share).
  • Recorded normalized earnings before interest, income taxes, depreciation, and amortization (normalized EBITDA)¹ of $254 million, representing a 2% increase from the second quarter of 2025 due to higher contributions from maintenance capital expenditures for system integrity projects on the Keystone Pipeline System, offset by expected losses in the Marketing segment.
  • Reported distributable cash flow^{1 2} of $236 million, representing an increase of $69 million from the second quarter of 2025, driven primarily by changes in U.S. tax legislation and South Bow's tax optimization efforts.
• Maintained total long-term debt and net debt¹ outstanding of $5.8 billion and $4.8 billion, respectively, during the third quarter of 2025. The Company's net debt-to-normalized EBITDA ratio¹ was unchanged at 4.6 times as at Sept. 30, 2025.
• On Oct. 3, 2025, extended the tenor of the Company's C$2 billion revolving credit facility by one year, maturing on Oct. 3, 2029.

Returns to shareholders

• Declared dividends totalling $104 million or $0.50/share to shareholders during the third quarter of 2025.
• South Bow's board of directors (the Board) approved a quarterly dividend of $0.50/share, payable on Jan. 15, 2026, to shareholders of record at the close of business on Dec. 31, 2025. The dividends will be designated as eligible dividends for Canadian income tax purposes.

Corporate updates

• South Bow expects to complete the transition to its new supervisory control and data acquisition (SCADA) system in the fourth quarter of 2025, the final significant item in exiting the Transition Services Agreement (TSA) with TC Energy Corporation (TC Energy) as it relates to the spinoff transaction (the Spinoff).
• In early October, South Bow and associated parties mutually agreed to withdraw all complaints and protests relating to the variable toll disputes filed with the Canada Energy Regulator, the Federal Energy Regulatory Commission, the Court of King's Bench of Alberta, and the United States Court of Appeals for the District of Columbia Circuit.
  • As part of the Separation Agreement between South Bow and TC Energy, TC Energy indemnified South Bow for matters that existed prior to the Spinoff. Following the withdrawal of the variable toll disputes, South Bow reached its maximum indemnity liability of $22 million.

• The Board has approved South Bow's 2026 budget, which is focused on strengthening the Company's financial position, maturing and executing a portfolio of organic and inorganic growth opportunities, and delivering strong and sustainable returns to shareholders. Normalized EBITDA is projected to be approximately $1.03 billion, within a range of 2%, with approximately 90% secured through committed arrangements. See "2026 guidance" of this news release for additional details.

South Bow's unaudited consolidated interim financial statements and notes (the financial statements), and management's discussion and analysis (MD&A) as at and for the three and nine months ended Sept. 30, 2025 (the Q3 2025 MD&A) are available on South Bow's website at www.southbow.com, under South Bow's SEDAR+ profile at www.sedarplus.ca, and in South Bow's filings with the U.S. Securities and Exchange Commission (SEC) at www.sec.gov.

Milepost 171 incident

• Following the MP-171 incident, the Pipeline and Hazardous Materials Safety Administration (PHMSA) issued a Corrective Action Order (CAO) requiring South Bow to undertake corrective actions, including operating under pressure restrictions for specific segments of the pipeline.
• Total costs relating to the incident, estimated at approximately $55 million, are largely expected to be recovered through the Company's insurance policies by early 2026. As of Sept. 30, 2025, South Bow has received approximately $16 million in reimbursements under its insurance policies.
• The timing of PHMSA's expected release of the independent third-party root cause analysis (RCA) has been impacted by the U.S. federal government shutdown.
  

Initial findings

• According to the mechanical and metallurgical analysis, both the pipe and welds conformed to industry standards for design, materials, and mechanical properties.
• The failure resulted from a fatigue crack that originated along the pipe's manufactured long-seam weld.

Remedial actions

• South Bow is actively progressing its remedial actions, with six in-line inspection runs and 37 integrity digs completed to date. Preliminary results indicate no injurious issues.
• The in-line inspection process has been modified to address tool limitations by overlaying data from previous tool runs and implementing improvements in data analysis methods. South Bow will continue to work closely with its in-line inspection technology vendors to advance tool performance and validation, address and resolve tool limitations, and develop new technologies.
• Additional in-line inspection tool runs and integrity digs are planned for 2025 and 2026 as part of South Bow's comprehensive program to address the findings and recommendations from the RCA investigation.
• As part of PHMSA's CAO, South Bow is finalizing its remedial work plan to submit to the regulator for approval. This plan includes the corrective actions already completed. As South Bow conducts this remedial work, any findings will be incorporated into the plan and the Company's programs to enhance system integrity and ensure safe operations. South Bow is committed to maintaining transparency with its regulators, customers, and industry peers throughout this process.
  

Outlook

Market outlook

• Western Canadian Sedimentary Basin (WCSB) crude oil supply is expected to grow modestly throughout 2026 and remain below available pipeline egress capacity, resulting in continued low demand for uncommitted capacity on the Keystone Pipeline.
• Pricing differentials impacting the rates South Bow can charge for capacity on the U.S. Gulf Coast segment of its Keystone Pipeline System are expected to remain tight throughout 2026.

Guidance

• South Bow's guidance aims to inform readers about Management's expectations for 2025 and 2026 financial and operational results. Readers are cautioned that these estimates may not be suitable for any other purpose. See "Forward-looking information and statements" of this news release for additional information regarding factors that could cause actual events to be significantly different from those expected.
  

2025 guidance

• South Bow is reaffirming its 2025 guidance for normalized EBITDA, including forecasting the Marketing segment to be approximately $30 million lower in 2025 compared to 2024.
• South Bow is revising its outlook for distributable cash flow in 2025 to $700 million, within a range of 2%, to reflect lower expected current taxes resulting from changes in U.S. tax legislation and South Bow's tax optimization efforts, and higher expected interest income and other. With lower expected current taxes in 2025, South Bow's effective tax rate is now expected to range between 20% and 21%.
• All other guidance items remain unchanged.
  

South Bow's updated 2025 annual guidance is outlined below:

Normalized net income and normalized net income per share

Normalized net income represents net income adjusted for the normalizing items described above and is used by Management to assess the earnings that are representative of South Bow's operations. By adjusting for non-recurring items and other factors that do not reflect the Company's ongoing performance, normalized net income provides a clearer picture of the Company's continuing operations. This measure is particularly useful for investors as it allows for a more accurate comparison of financial performance and trends across different periods. On a per-share basis, normalized net income is derived by dividing the normalized net income by the weighted average common shares outstanding at the end of the period. Management believes this per-share measure is valuable for investors as it provides insight into South Bow's profitability on a per-share basis, assisting in evaluating the Company's performance.

The following table reconciles net income to normalized net income for the indicated periods:

$ millions, except common shares outstanding and per share amounts	Three Months Ended						Nine Months Ended

Distributable cash flow

Distributable cash flow is used to assess the cash generated through business operations that can be used for South Bow's capital allocation decisions, helping investors understand the Company's cash-generating capabilities and its potential for returning value to shareholders. Distributable cash flow is based on income (loss) before income taxes, adjusted for depreciation and amortization, the normalizing items discussed above, and further adjusted for specific items, including income and distributions from the Company's equity investments, maintenance capital expenditures, which are capitalized and generally recoverable through South Bow's tolling arrangements, and current income taxes.

Distributable cash flow guidance is a forward-looking non-GAAP financial measure. South Bow does not provide a reconciliation of such forward-looking measure to the most directly comparable financial measure calculated and presented in accordance with GAAP due to unknown variables and the uncertainty related to future results. These unknown variables may be inherently difficult to determine without reasonable efforts.

In the second quarter of 2025, South Bow modified the definition of distributable cash flow to no longer adjust income (loss) before income taxes for interest income and other. Management believes that this modified definition of distributable cash flow more accurately reflects the amount of cash generated through business operations that can be used for South Bow's capital allocation decisions. Comparative measures have been restated to reflect these changes.

The following table reconciles income (loss) before income taxes to distributable cash flow for the indicated periods:

$ millions	Three Months Ended						Nine Months Ended
	June 30, 2025		Sept. 30, 2025		Sept. 30, 2024		Sept. 30, 2025		Sept. 30, 2024

Net debt and net debt-to-normalized EBITDA ratio

Net debt is used as a key leverage measure to assess and monitor South Bow's financing structure, providing an overview of the Company's long-term debt obligations, net of cash and cash equivalents. Management believes this measure is useful for investors as it offers insights into the Company's financial health and its ability to manage and service its debt obligations. Net debt is defined as the sum of total long-term debt with 50% equity treatment of the Company's junior subordinated notes, operating lease liabilities, and dividends payable, less cash and cash equivalents, per the Company's consolidated balance sheets.

Net debt-to-normalized EBITDA ratio is used to monitor South Bow's leverage position relative to its normalized EBITDA for the trailing four quarters. This ratio provides investors with insight into the Company's ability to service its long-term debt obligations relative to its operational performance. A lower ratio indicates stronger financial health and greater capacity to meet its debt obligations.
