SOBO South Bow Corporation

South Bow Corp. (TSX & NYSE: SOBO) (South Bow or the Company) reports its fourth-quarter and year-end 2024 financial and operational results and provides its 2025 outlook. Unless otherwise noted, all financial figures in this news release are in U.S. dollars.

Highlights

Spinoff transaction

• Launched as an independent company on Oct. 1, 2024, completing the planned separation (the Spinoff) from TC Energy Corp. (TC Energy).
• Completed an initial notes offering on Aug. 28, 2024, raising approximately $5.8 billion, in aggregate, of U.S. and Canadian dollar-denominated senior unsecured notes and U.S. dollar-denominated junior subordinated notes. As part of the Spinoff, South Bow repaid the outstanding long-term debt owed to affiliates of TC Energy on Oct. 1, 2024.

Safety and operational performance

• Demonstrated safety excellence in 2024, achieving record occupational and process safety performance during a transformative period.
• Delivered record system availability in 2024, with an annual System Operating Factor (SOF) of 95% for the Keystone Pipeline due to continued improvements in system reliability.
• Recorded annual average throughput on the Keystone Pipeline of approximately 626,000 barrels per day (bbl/d) in 2024, an increase of 5% relative to 2023. Throughput on the U.S. Gulf Coast segment of the Keystone Pipeline System averaged approximately 795,000 bbl/d, increasing by 15% relative to 2023.
  • Fourth-quarter 2024 throughput on the Keystone Pipeline and the U.S. Gulf Coast segment of the Keystone Pipeline System averaged approximately 621,000 bbl/d and approximately 784,000 bbl/d, respectively.
• Advanced the Blackrod Connection Project in Alberta, anticipated to be ready for in-service in early 2026. South Bow is in the final stages of completing construction of the project’s 25-km crude oil and natural gas pipeline segments, with welding complete and hydrostatic testing activities underway. Facility construction, including the tank terminal, is expected to be completed in late 2025.
• Received approval from the Pipeline and Hazardous Materials Safety Administration (PHMSA) in Jan. 2025 of South Bow’s remedial work plan, substantially completing the conditions in the Amended Corrective Action Order (ACAO) related to the Milepost 14 incident (MP-14). In early March 2025, South Bow received approval from PHMSA to lift the pressure restriction on the affected segment to 72% of the specified minimum yield strength of the pipeline. The affected segment includes the section of the pipeline where the MP-14 incident occurred.

Financial performance

• Delivered strong financial performance in 2024, underscored by the highly contracted nature of South Bow’s assets. Revenue and normalized earnings before interest, income taxes, depreciation, and amortization (normalized EBITDA) increased relative to 2023 due to significant demand for uncommitted capacity on the Keystone Pipeline in the first quarter of 2024, and strong demand for capacity on the U.S. Gulf Coast segment of the Keystone Pipeline System throughout the year.
  • Generated revenue of $488 million and $2,120 million for the three months and year ended Dec. 31, 2024, respectively.
  • Recognized net income of $55 million ($0.26/share) and $316 million ($1.52/share) during the three months and year ended Dec. 31, 2024, respectively.
  • Recorded normalized EBITDA1 of $290 million for the three months ended Dec. 31, 2024, an increase of 11% from the three months ended Sept. 30, 2024, primarily due to the timing of trade settlements within South Bow’s Marketing segment. Normalized EBITDA for the year ended Dec. 31, 2024 was $1,091 million, an increase of 2% from 2023.
  • Delivered distributable cash flow1 of $183 million and $608 million for the three months and year ended Dec. 31, 2024, respectively.
• Exited 2024 with total long-term debt and net debt1 outstanding of $5.7 billion and $4.9 billion, respectively. South Bow’s net debt-to-normalized EBITDA ratio1 was 4.5 times at Dec. 31, 2024, supported by the Company’s starting working capital balances and strong normalized EBITDA generated in 2024.
  • South Bow expects that its net debt-to-normalized EBITDA ratio will increase modestly through the course of 2025 as the Company continues to invest in the Blackrod Connection Project and incur one-time costs of approximately $40 million to $50 million associated with the Spinoff. Consistent with the Company’s outlook on leverage, South Bow anticipates exiting 2025 with a net debt-to-normalized EBITDA ratio of approximately 4.8 times and that the Company will begin reducing its leverage once the Blackrod Connection Project starts generating cash flow in 2026.

Returns to shareholders

• Committed to paying a strong and sustainable dividend, declared South Bow’s inaugural quarterly dividend of $104 million ($0.50/share) on Nov. 7, 2024. The dividend was paid on Jan. 31, 2025 to shareholders of record on Dec. 31, 2024.
• South Bow’s board of directors (the Board) has approved a quarterly dividend of $0.50/share, payable on April 15, 2025 to shareholders of record at the close of business on March 31, 2025. The dividends will be designated as eligible dividends for Canadian income tax purposes.

South Bow's audited consolidated financial statements and notes (the financial statements), management's discussion and analysis (MD&A), and annual information form (AIF) as at and for the year ended Dec. 31, 2024 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. The disclosure under the section "Non-GAAP Financial Measures" in South Bow's MD&A as at and for the year ended Dec. 31, 2024 is incorporated by reference into this news release.

South Bow's standalone financial statements were prepared using information derived from the consolidated financial statements and accounting records of TC Energy, including the historical cost basis of assets and liabilities comprising the Company, as well as the historical revenues, direct costs, and allocations of indirect costs attributable to the operations of the Company, using the historical accounting policies applied by TC Energy. The presentation of certain prior period comparatives have been updated for consistency with current year presentation.

Outlook

Capital allocation priorities

• South Bow takes a disciplined approach to capital allocation to preserve optionality and maximize total shareholder returns over the long term. The Company’s capital allocation priorities are built on a foundation of financial strength and supported by South Bow’s stable, predictable cash flows. South Bow’s capital allocation priorities include:
  • paying a sustainable base dividend;
  • strengthening the Company’s investment-grade financial position; and
  • leveraging existing infrastructure within South Bow’s strategic corridor to offer customers competitive connections and enhanced optionality.

Market outlook

• Every day, South Bow safely and reliably transports crude oil to key demand and refining markets in the U.S. Midwest and Gulf Coast. With substantially all of the crude oil imported into the U.S. Midwest originating from Canada, and refining facilities in the U.S. Gulf Coast set up to process heavy crude oil, these markets rely heavily on Canadian crude oil supplies to meet their energy needs.
• While approximately 90% of South Bow’s normalized EBITDA is contracted through committed arrangements, which carry minimal commodity price or volumetric risk, demand for uncommitted capacity on the Keystone System is anticipated to remain subdued in 2025 as Western Canadian Sedimentary Basin (WCSB) crude oil pipeline capacity exceeds supply.
• The potential for, and continuation of, tariffs on energy imposed by the U.S. government and counter-tariffs imposed by the Canadian government have created economic and geopolitical uncertainty, resulting in volatility in pricing differentials. Persistence of this uncertainty may create additional headwinds for uncommitted capacity on South Bow’s pipeline systems and impact South Bow’s Marketing segment results. Given the uncertainty, South Bow’s guidance for 2025 does not account for the future potential impact of sustained tariffs.

2025 guidance

• South Bow’s guidance aims to inform readers about Management’s expectations for financial and operational results in 2025. 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.
• The financial outlook for South Bow in 2025 is supported by the Company’s highly contracted cash flows and strong structural demand for services. Normalized EBITDA is projected to be approximately $1.01 billion, within a range of 3%, with approximately 90% secured through committed arrangements. South Bow reaffirms its long-term normalized EBITDA growth outlook of 2% to 3%.
• South Bow has reduced its outlook for normalized EBITDA for its Marketing segment by approximately $30 million relative to 2024, due to continued impacts of WCSB crude oil pipeline capacity exceeding supply and South Bow’s response to market uncertainty caused by the potential for, and continuation of, tariffs, including the unwinding of certain positions to minimize South Bow’s exposure to further pricing volatility.
• South Bow anticipates that its interest expense for 2025 will be approximately $325 million, within a range of 2%, and that the Company’s current tax rate will range from 23% to 24%.
• Distributable cash flow is expected to be approximately $535 million, within a range of 3%, which South Bow will use to fund its expected annual dividend of $416 million ($2.00/share), subject to approval and declaration by the Board, and investments required to continue advancing the Blackrod Connection Project.
• South Bow expects that its net debt-to-normalized EBITDA ratio will increase modestly through the course of 2025 as the Company continues to invest in the Blackrod Connection Project and incur one-time costs of approximately $40 million to $50 million associated with the Spinoff. Consistent with the Company’s outlook on leverage, South Bow anticipates exiting 2025 with a net debt-to-normalized EBITDA ratio of approximately 4.8 times and that the Company will begin reducing its leverage once the Blackrod Connection Project starts generating cash flow in 2026.
• South Bow plans to invest approximately $110 million, within a range of 3%, in growth capital expenditures for the Blackrod Connection Project in 2025. The total expected capital cost of the project is estimated to be $180 million, targeted to be ready for in-service in early 2026. As of Dec. 31, 2024, South Bow has invested $62 million in the project.
• Maintenance capital expenditures are estimated to be approximately $65 million, within a range of 3%, in 2025, as South Bow proactively completes maintenance activities while demand for uncommitted capacity is expected to be subdued, and invests in information services infrastructure. These expenditures are generally recoverable through South Bow’s tolling arrangements.

Non-GAAP financial measures

In this news release, South Bow references certain non-GAAP financial measures and non-GAAP ratios that do not have standardized meanings under GAAP and may not be comparable to similar measures presented by other entities. These non-GAAP measures include or exclude adjustments to the composition of the most directly comparable GAAP measures. Management considers these non-GAAP financial measures and non-GAAP ratios to be important in evaluating and understanding the operational performance and liquidity of South Bow. These non-GAAP measures and non-GAAP ratios should not be considered in isolation or as a substitute for financial information presented in accordance with GAAP.

South Bow’s non-GAAP financial measures and non-GAAP ratios include:

• normalized EBITDA;
• normalized net income;
• normalized net income per share;
• distributable cash flow;
• net debt; and
• net debt-to-normalized EBITDA ratio.

These measures and ratios are further described below, with a reconciliation to their most directly comparable GAAP measure.

Normalizing items

Normalized measures are, or include, non-GAAP financial measures and ratios and include normalized EBITDA, normalized net income, normalized net income per share, distributable cash flow, and net debt-to-normalized EBITDA ratio. Management uses these normalized measures to assess the financial performance of South Bow’s operations and compare period-over-period results. During certain reporting periods, the Company may incur costs that are not indicative of core operations or results. These normalized measures represent income (losses), adjusted for specific normalizing items that are believed to be significant; however, they are not reflective of South Bow’s underlying operations in the period.

These specific items include gains or losses on sales of assets or assets held for sale, unrealized fair value adjustments related to risk management activities, acquisition, integration, and restructuring costs, and other charges, including but not limited to, impairment, contractual costs, and settlements.

South Bow excludes the unrealized fair value adjustments related to risk management activities, as these represent the changes in the fair value of derivatives, but do not accurately reflect the gains and losses that will be realized at settlement and impact income. Therefore, South Bow does not consider them reflective of the Company’s underlying operations, despite providing effective economic hedges. Realized gains and losses on grade financial contracts are adjusted to improve comparability, as they settle in a subsequent period to the underlying transaction they are hedged against.

Separation costs relate to internal costs and external fees incurred specific to the Spinoff. These items have been excluded from normalized measures, as Management does not consider them reflective of ongoing operations and they are non-recurring in nature.

Normalized EBITDA

Normalized EBITDA is used as a measure of earnings from ongoing operations. Management uses this measure to monitor and evaluate the financial performance of the Company’s operations and to identify and evaluate trends. This measure is useful for investors as it allows for a more accurate comparison of financial performance of the Company across periods for ongoing operations. Normalized EBITDA represents income before income taxes, adjusted for the normalizing items, in addition to excluding charges for depreciation and amortization, interest expense, and interest income.

The following table reconciles income (loss) before income taxes to normalized EBITDA for the indicated periods:

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. 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:

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 before income taxes, adjusted for depreciation and amortization, interest income and other, 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.

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

$ millions	Three Months Ended						Year Ended

2. Maintenance capital expenditures are generally recoverable through South Bow’s tolling arrangements.

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. 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% 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 the 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.
