South Bow has rewarded shareholders with a 41.9% return over the past year, yet on broad valuation checks the stock no longer looks plainly cheap or clearly expensive at current levels.
The issue now is whether South Bow's recent share price gain has already absorbed most of that valuation support or if there is still a margin of safety left for new investors.
Find out why South Bow's 41.9% return over the last year is lagging behind its peers.
The P/E ratio is a useful way to look at South Bow because it links what you pay today to the earnings the company is currently generating. It also lets you line it up quickly against other oil and gas stocks.
South Bow trades on a P/E of about 16.6x, which is lower than the Oil and Gas industry average of around 21.2x and well below the peer group average near 27.1x. The Fair Ratio model, which looks at factors such as growth profile, margins, size and risk, points to a P/E of about 18.1x as a reasonable anchor. That is slightly above where the stock trades now, indicating only a modest gap between the current market price and what this framework implies.
Despite the strong Q2 2026 earnings beat and higher 2026 EBITDA outlook lifting sentiment, South Bow's current P/E still sits close to this Fair Ratio estimate rather than moving up to peer-like levels.
Overall, South Bow appears roughly fairly valued on the P/E multiple with only a small discount to its modelled fair level.

Bull case: 16% undervalued

South Bow now appears fairly valued on the P/E checks, with only a small discount implied by the Fair Ratio model. This leaves less room for a straightforward valuation benefit and places greater importance on execution. The key question from here is whether South Bow can deliver on its pipeline project plans without major setbacks. If progress stays on track, today’s valuation could represent a reasonable entry point. If delays or regulatory issues emerge, the current pricing may begin to look stretched.
