Santos shares are up 31% since early 2025, Transurban 17% above its low. Here's how to check if the run has room using EV/EBITDA and dividend yield.
The Santos Ltd (ASX:STO) share price has climbed 31.2% since the start of 2025. Transurban Group (ASX:TCL) shares trade 17.1% above their 52-week low. After moves of that size, a simple valuation check can help decide whether the run has room or is getting stretched.
Start with Santos. Oil and gas producers are typically valued on enterprise value relative to earnings before interest, tax, depreciation and amortisation. EV/EBITDA captures debt and is less distorted by depreciation than a plain price-to-earnings ratio. Santos's Barossa project ramp-up is a key production driver. The company reported a 3% rise in quarterly output in February, with first gas from Barossa on track for mid-2026. A rising production base can support EBITDA even if crude prices soften. Investors should track the EV/EBITDA multiple against Santos's own five-year range and against peer Woodside. If the multiple sits above the mid-cycle average, the rally may already price in the Barossa contribution. If it is below, the stock could offer value for those willing to wait for output to hit the income statement. Santos reports its next quarterly production data in April. That print will either confirm the ramp-up trajectory or raise questions about timing.

Transurban is a different beast. Toll-road operators are valued on dividend yield and discounted cash flow, because free cash flow is lumpy and debt is high. Transurban's yield is a function of traffic growth, toll escalation and construction spend on projects like Sydney's M12 and Brisbane's Logan Enhancement. The current yield, relative to the ASX 200 average and to the company's own historical bands, tells you whether the market is pricing in too much or too little growth. A yield below 3.5% in the current rate environment would imply investors are paying up for future traffic. A yield above 4.5% would suggest the opposite – the market is discounting the project pipeline. Traffic data releases are the primary catalysts. A sustained uptick in vehicle movements can push the yield lower as the share price rises. Transurban's next traffic update is due in March. That release will show whether the post-pandemic recovery in commuter and freight volumes is holding. For a broader framework on valuing ASX stocks with different cash-flow profiles, the Valuing FLT and STO: 2026 Growth vs. Dividend Strategy piece covers similar ground.
Neither metric works in isolation. For Santos, the EV/EBITDA reading needs to be checked against oil-price assumptions and the Barossa schedule. For Transurban, the yield must be viewed alongside debt levels and the timing of major capital outlays. The discipline of picking one benchmark per company forces a concrete question: is the share price in line with the underlying earnings and cash-flow trajectory? The April production data for Santos and the March traffic update for Transurban will provide the next real answers.
