Woodside Energy vs Santos shares: Which is the better investment?

WDS vs STO: How to split them

If you are choosing between Woodside Energy and Santos shares, you are making a choice between two different styles of ASX energy investment. Woodside is the larger, more globally exposed LNG and oil major with more scale, a bigger balance sheet, and a clearer “major-projects plus shareholder returns” profile. Santos is the smaller, cheaper, more domestically familiar energy producer, with a strong base business and meaningful project upside, but less scale and less room for error.

Woodside’s latest official result is its 2025 full-year result, released on 24 February 2026, while Santos has gone one step further and already released its 2026 first-quarter report on 23 April 2026. Woodside reported US$12.984 billion of operating revenue, US$2.649 billion of underlying NPAT, record production of 198.8 MMboe, and a 112 US cent full-year dividend for 2025. Santos’ latest quarterly update reported 22.5 mmboe of production in Q1 2026, up 1% on the prior quarter and 3% year over year, plus US$383 million in free cash flow from operations.

So the real question for you is not which company is “better”, it is whether you want the higher-quality, larger-scale energy major, or the cheaper, more value-tilted energy stock. In that framing, Woodside is usually the cleaner all-rounder, while Santos is usually the more valuation-sensitive pick.

Why Choose Woodside Energy

If you want the bigger and cleaner energy franchise, Woodside has the stronger case as more complete energy major. The company’s 2025 full-year result showed stable EBITDA, record production, strong liquidity, and a business still moving major projects forward. Management highlighted that Scarborough was 94% complete at year-end and remained on track for first LNG cargo in Q4 2026, which is a major part of the Woodside investment story from here.

It has the larger portfolio, stronger LNG positioning, and more obvious scale advantages. In its 2025 full-year result, Woodside reported record production of 198.8 MMboe, US$9.277 billion EBITDA, US$2.718 billion NPAT, and US$2.649 billion underlying NPAT. It also reported US$9.3 billion of liquidity, gearing of 18.2%, and net debt to EBITDA of 0.9x, which gives it a strong balance-sheet profile relative to its project commitments.

There is also a very clear project-driven reason to own it. Woodside said Scarborough was 94% complete at year-end and remained on track for first LNG cargo in the fourth quarter of 2026. That matters because Scarborough is one of the biggest tangible growth drivers in the ASX energy space, and it gives Woodside a more visible medium-term production and cash-flow runway than Santos.

The downside is that Woodside is still an energy major. That means commodity prices, project execution, and LNG market conditions all matter. The 2025 result also showed that revenue was down slightly year over year, with lower realised prices offsetting some of the strong operating performance. So even the stronger business is not immune to cyclicality.

Woodside makes the most sense if you want the higher-quality, larger-scale energy stock and are comfortable owning a business where the core attraction is durability plus major-project upside.

Why Choose Santos

If you want the stock that looks more like a disciplined value-and-projects story, Santos is more naturally positioned that way. Santos’ 2025 full-year materials described a “strong base business performance and dividend growth,” while the 2026 first-quarter report showed continued production growth and strong free cash flow generation. The company is coming out of a heavy capex phase and is trying to convert that into stronger production and cash generation, which is why the investment case can look appealing if you think the operational delivery continues.

Santos is smaller and less diversified than Woodside, but it still has a solid energy portfolio and a strong base business. Its 2025 full-year results showed US$4.939 billion in sales revenue, and the company described the result as demonstrating the continued strength of its disciplined low-cost operating model and dividend growth. Its latest Q1 2026 report then showed 22.5 mmboe of production, up 1% quarter on quarter and 3% year on year, plus US$383 million in free cash flow from operations.

That is why Santos can appeal if you want a more “improving business” style of energy investment. The market case is that the company has already spent through a heavy development phase and is now getting closer to the payoff. That can work well if production ramps smoothly and capital intensity eases. The company’s recent AGM messaging also said it is preparing for a 25% to 30% increase in production, which reinforces that transition from build-out to delivery.

The risk is that Santos has less margin for error. It does not have Woodside’s scale, and while the portfolio is solid, the story depends more on continued execution. On the current figures, Santos also does not screen as clearly cheaper on earnings as you might expect, which weakens the “buy the cheaper one” argument a bit. So Santos is more attractive if you specifically want a smaller-cap energy name with operational momentum, not if you simply want the strongest energy franchise.

Dividend, Income & Valuation

If income matters to you, Woodside has the better case right now. The current data shows a dividend yield of 3.64% for Woodside versus 3.19% for Santos. That lines up with the latest official where Woodside’s 2025 full-year result included a 112 US cent full-year dividend, while Santos’ 2025 full-year communications emphasized dividend growth but do not present a stronger current income case than Woodside.

So if your first priority is yield from an ASX energy stock, Woodside looks better.

When it comes to valuation, this one may surprise some.

• Woodside: ~15.9x earnings
• Santos: ~22.0x earnings

Interestingly, that means Santos is not the obvious valuation winner on current earnings multiples which many investors instinctively assume, that the smaller company must be cheaper. If you care about what you are paying for current earnings, Woodside actually looks easier to defend. Santos’ counterargument is that you may be paying for future production growth and project delivery, but that is a more execution-dependent case.

Woodside also has the stronger profit margin, stronger ROE, stronger EBITDA base, and slightly better earnings trend.

The Better Long Term Investment

If you want the stock you can own more comfortably through a cycle, Woodside has the better long-term investment case. It has more scale, a bigger earnings base, stronger balance-sheet flexibility, and a more obvious major-project catalyst in Scarborough. The company’s 2025 result makes it clear that management is trying to balance growth, shareholder returns, and resilience, and the current project timeline gives you a visible medium-term path.

If you want the stock with the more operationally improving profile, Santos can still make sense, but the case is less straightforward. You are relying more on the company turning recent investment into higher production and stronger free cash flow. That can absolutely work, especially after the encouraging Q1 2026 update, but it is a less obvious “just buy the better business” case than Woodside.

Woodside shapes up as the larger business, the stronger current operator, and the better income stock on the present numbers, and the one with the clearer near-term major-project catalyst through Scarborough. It also does not ask you to pay more than Santos on current earnings multiples. That combination makes it the more compelling all-round choice.

Santos is not a bad option, but it is the stock for you if you specifically want the smaller, more execution-sensitive energy name and you believe the next phase of production growth will materially change the earnings profile. The latest quarter shows progress, but the investment case still depends more on delivery than Woodside’s does.
