STO has rallied 17.6% in 2025 while TCL remains near its lows. A simple valuation approach can help decide which offers better value based on commodity cycles and infrastructure cash flows.
The Santos Ltd (ASX:STO) share price and Transurban Group (ASX:TCL) share price are in focus in 2026. Here is a way to put a value on them.
STO has risen 17.6% since the start of 2025. TCL sits about 8.6% above its 52-week low. The difference in performance reflects their different businesses. Santos is an oil and gas producer tied to commodity cycles. Transurban is a toll road operator with regulated revenues.
A simple approach for STO uses the price-to-earnings ratio. Compare the forward P/E to the sector average and to its own five-year range. If the multiple is below the historical mid-point and the oil price outlook is stable, the stock may be cheap. Production growth from the Barossa project could support higher earnings. For more context on Santos operations, see the recent production update.
Transurban requires a different lens. Infrastructure stocks are often valued on dividend yield and the regulated asset base. The yield relative to government bond rates matters. If the yield is above the sector average and traffic volumes are recovering, the stock offers income with low volatility. The company's next regulatory determination will set allowed returns for years ahead.

These two stocks do not compete in the same sector. Each has a clear valuation anchor. STO's anchor is the oil price and production volume. TCL's anchor is traffic growth and regulation. Investors can pick the one that fits their view on commodities versus infrastructure.
The next catalyst for STO is the quarterly production report due in April. That will show if Barossa is ramping as expected. For TCL, the annual revenue decision in June will set the tone for the stock.
