South Bow heads into its third-quarter report with an unusual split between its near-term numbers and its long-term story. Last quarter management delivered the company's first guidance raise since becoming a standalone business and unveiled a contracted growth project. It also warned that the second half of 2026 would look modest next to a strong first half. This report is the first real test of that warning, and of whether the growth narrative can carry the stock through a softer stretch of earnings.

Wall Street expects earnings of $0.43 per share on revenue of about $484.8 million when results arrive after the close on November 4. That revenue figure would be roughly 5% above the year-ago quarter but well below the $546 million posted last quarter. Earnings are projected to fall about 8.5% from a year ago and to drop meaningfully from the prior quarter's $0.50. Put simply, the Street has already accepted management's message that the first half was the high-water mark for 2026. Revenue growth paired with an earnings decline suggests analysts expect costs or below-the-line items to absorb some of the top-line gain, so margin commentary deserves attention.

The bigger question is whether the raised full-year targets of $1.04 billion in normalized EBITDA and $665 million in distributable cash flow still look secure. Because so much of the year's strength was front-loaded, a reaffirmation would effectively confirm that the second-half slowdown is playing out as planned rather than worse. Management tied the expected cooling partly to crude inventories at Hardesty and Cushing sitting at all-time lows, which limits spot shipping opportunities. Any sign that spot volumes have weakened beyond that expectation, or that Gulf Coast throughput has retreated sharply from last quarter's records, would challenge the guidance raise. Continued strength in Gulf Coast demand, by contrast, would suggest the upgrade had more substance than a one-time bump.

Operational housekeeping matters too. The pressure restrictions around Milepost 171 are expected to be lifted in phases through the end of 2026 and into 2027, so an update on that timeline would show whether full system capacity is coming back on schedule. Leverage is another useful indicator. Net debt to EBITDA improved to 4.4 times last quarter on the way to a 4.0 times target, and further progress would matter more now that growth capital spending is rising to support Prairie Connector and the Liberty Bridge venture with Bridger.

Those projects are the real reason to listen to the call. The open season secured 465,000 barrels per day of 20-year commitments, with a final investment decision targeted for mid-2027 and service by the end of 2028. The unresolved piece is permit durability, which management hopes to address through a layered set of government-backed protections in both the U.S. and Canada. Concrete progress on that structure would materially de-risk the project. Silence, or new friction from Montana opposition or talk of a competing West Coast pipeline, would keep a discount on the story.

The market has not paid much for last quarter's good news. Shares have slipped 1.7% since the prior report, trailing the S&P 500 slightly, and sentiment has cooled to modestly bullish from a somewhat warmer reading a quarter ago. At $35.69, the stock sits above its 200-day moving average and near the middle of its post-earnings range, well short of the $39.02 high. That leaves a fairly neutral bar. In the end, the report will be judged on one issue: whether South Bow can keep full-year guidance intact through the expected lull while showing tangible progress on the permit protections that stand between Prairie Connector and a final investment decision.
