CALGARY, Alberta, May 07, 2026 (GLOBE NEWSWIRE) -- South Bow Corp. ((TSX &, NYSE:SOBO) (South Bow or the Company) reports its first-quarter 2026 financial and operational results. Unless otherwise noted, all financial figures in this news release are presented in U.S. dollars.

Highlights

Safety and operational performance

Recorded first-quarter 2026 average throughput of approximately 616,000 barrels per day (bbl/d) on the Keystone Pipeline due to strong operational performance, including a System Operating Factor (SOF) of 95%. Throughput on the U.S. Gulf Coast segment of the Keystone Pipeline System averaged approximately 709,000 bbl/d.
As disclosed on March 5, 2026, placed the Blackrod Connection Project into commercial service during the first quarter of 2026, on schedule, on budget, and with a zero recordable case rate. Cash flows are expected to increase throughout the second half of 2026 and into 2027, with the project expected to contribute approximately $10 million in normalized earnings before interest, income taxes, depreciation, and amortization (normalized EBITDA)¹ in 2026.
Progressed remedial actions relating to the Milepost 171 (MP-171) incident, including completing 11 in-line inspections and 76 integrity digs to date, and continuing to work closely with the Company's in-line inspection technology vendors. As South Bow conducts its remedial work, findings are being incorporated into the Company's remedial work plan and ongoing programs to enhance system integrity and ensure safe operations.

Financial performance

Delivered stable financial results in the first quarter of 2026 amid ongoing geopolitical and market uncertainty. South Bow generated revenue of $491 million, and reported net income of $77 million ($0.37/share), normalized EBITDA of $257 million, and distributable cash flow¹ of $168 million.
- Normalized EBITDA of $257 million increased by $5 million from the fourth quarter of 2025. This increase was primarily due to higher contributions from the Marketing segment, and was partially offset by lower normalized EBITDA in the Keystone Pipeline System segment, reflecting reduced maintenance activities.
- Distributable cash flow of $168 million increased by $19 million from the fourth quarter of 2025, driven primarily by lower current taxes.
Maintained total long-term debt and net debt¹ outstanding of $5.8 billion and $4.7 billion, respectively, in the first quarter of 2026. As at March 31, 2026, the Company's net debt-to-normalized EBITDA ratio¹ was 4.7 times.

Returns to shareholders

Returned $104 million or $0.50/share to shareholders in the first quarter of 2026 through South Bow's sustainable dividend.
South Bow's board of directors (the Board) approved a quarterly dividend of $0.50/share, payable on July 15, 2026, to shareholders of record at the close of business on June 30, 2026. The dividends will be designated as eligible dividends for Canadian income tax purposes.

Corporate updates

Closed bids for the previously announced open season on March 30, 2026, which solicited commitments for long-term firm transportation service from Hardisty, Alta., to multiple U.S. delivery points, including Cushing, Okla., and destinations on the U.S. Gulf Coast. A 60-day period is underway to determine whether sufficient commercial support exists to advance the proposed Prairie Connector project. At the end of this evaluation period, South Bow will provide the results of the open season and, if advanced, indicate the project's potential next steps.

South Bow's unaudited consolidated interim financial statements and notes (the financial statements) as at and for the three months ended March 31, 2026 and related management's discussion and analysis (the Q1 2026 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.

Outlook

Market outlook

Recent geopolitical events have caused significant market volatility, underscoring the importance of a secure and reliable energy supply. While commodity prices have strengthened in response to the geopolitical events, the pricing differentials that drive contributions from uncommitted capacity on South Bow's Keystone Pipeline have not materially changed.
South Bow continues to expect that Western Canadian Sedimentary Basin (WCSB) crude oil supply will grow modestly throughout 2026 and remain below total pipeline egress capacity.
Physical crude oil market constraints resulting from recent geopolitical events have led to stronger demand for capacity on the U.S. Gulf Coast segment of South Bow's Keystone Pipeline System.

2026 guidance

South Bow's annual guidance aims to inform readers about Management's expectations for 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.
South Bow is reaffirming its 2026 annual guidance, with the Company's financial outlook underpinned by highly contracted cash flows and strong structural demand for services. Normalized EBITDA is projected to be approximately $1.03 billion, within a range of 2%, with approximately 90% secured through committed arrangements, which carry minimal commodity price or volumetric risk.
Normalized EBITDA for the second quarter of 2026 is expected to be slightly higher than first-quarter 2026 normalized EBITDA of $257 million, primarily due to expected elevated demand on the Company's U.S. Gulf Coast segment of its Keystone Pipeline System.
South Bow will update its outlook for growth capital expenditures once it sanctions its next development project. The Company continues to expect its net debt-to-normalized EBITDA ratio to decrease modestly through 2026.

South Bow's 2026 annual guidance and results for the three months ended March 31, 2026 are outlined below:

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, enhanced optionality, and value chain expansions.

Specified financial measures

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 financial measures and non-GAAP ratios include 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 financial measures and non-GAAP ratios should not be considered in isolation or as a substitute for financial information or measures of performance presented in accordance with GAAP.

South Bow's non-GAAP financial measures used in this news release include:

normalized EBITDA;
segment normalized EBITDA;
normalized net income;
distributable cash flow; and
net debt.

South Bow's non-GAAP ratios used in this news release include:

normalized net income per share; and
net debt-to-normalized EBITDA ratio.

These non-GAAP financial measures and non-GAAP 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 non-GAAP ratios and include normalized EBITDA, segment 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 (loss), adjusted for specific normalizing items that are believed to be significant; however, are not reflective of South Bow's underlying operations in the period.

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

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 these items 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.

South Bow excludes tariff charges as they are not reflective of ongoing business conducted by the Company and are subject to uncertainty.

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 and segment normalized EBITDA

Normalized EBITDA and segment normalized EBITDA are used as measures of earnings from ongoing operations. Management uses these measures to monitor and evaluate the financial performance of the Company's operations and to identify and evaluate trends. These measures are useful for investors as they allow for a more accurate comparison of financial performance of the Company across periods for ongoing operations. Normalized EBITDA and segment normalized EBITDA represent income (loss) before income taxes, adjusted for the normalizing items, in addition to excluding charges for depreciation and amortization, interest expense, interest income and other, and other income.

Normalized EBITDA and segment normalized EBITDA guidance are forward-looking non-GAAP financial measures. South Bow does not provide a reconciliation of such forward-looking measures 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 unreasonable efforts. Guidance for normalized EBITDA and segment normalized EBITDA are calculated in the same manner as described above for historical normalized EBITDA and segment normalized EBITDA, as applicable.

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 under the heading "Normalizing items" 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 diluted 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

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 unreasonable 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
$ millions	Dec. 31, 2025		March 31, 2026		March 31, 2025
Income before income taxes	153		100		114

Maintenance capital expenditures are generally recoverable through South Bow's tolling arrangements.
Refers to adjustments made to normalized net income, net of tax, and includes other income, risk management instruments, Keystone variable toll disputes, separation costs, tariff charges, and Keystone XL costs and other.

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.

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.
