Santos vs Viva Energy shares: Which ASX energy stock stands out?
Investors looking at Santos Ltd (ASX: STO) and Viva Energy Group Ltd (ASX: VEA) are sizing up two heavyweights in Australia’s energy sector. Both play a vital role in supplying the fuel and energy keeping the nation running, but their businesses and financial profiles are quite different. Here’s how Santos and Viva Energy stack up for the everyday Aussie looking to buy into the local energy scene.
The case for Santos
Santos is a major oil and gas producer, based in Adelaide but operating across Australia, Papua New Guinea, Timor-Leste, and as far afield as Alaska. With decades of experience, it boasts one of Australia’s largest resource acreages and substantial infrastructure, especially for natural gas. The company’s reach covers both domestic supply and Asian export markets, and it’s busy developing big-ticket LNG projects.
Looking at the numbers, Santos commands a market cap of $27.77 billion, which makes it one of the largest ASX-listed energy names. Its shares are currently on a price-to-earnings ratio (P/E) of 26.58 and the stated dividend yield is 3.66%. EPS comes in at $0.225, and the declared dividend per share is $0.31. Santos has delivered an impressive year-to-date return of 41.1%.
When it comes to dividends, Santos’s record shows regular payouts, but recent dividends have been unfrankedâso investors in higher tax brackets may not get the full benefit. According to its most recent company profile, Santos continues to expand its LNG portfolio with projects like PNG LNG and Barossa LNG, supporting future growth, although it’s worth noting specific project updates weren’t available in the data supplied here.
The case for Viva Energy
Viva Energy is Australia’s second-largest refined fuel supplier and the exclusive Australian licensee of the Shell brand. It manages a major chunk of the nation’s fuel logistics: making, importing, blending, and distributing about a quarter of Australia’s demand. Viva owns the Geelong Refineryâone of just two left in the countryâand supplies over 1,300 branded service stations. In recent years, the business expanded into convenience store retailing after acquiring Coles Express and is eyeing new frontiers with natural gas and hydrogen technology.
Viva’s market cap sits at $5.26 billionâsmaller than Santos, but nothing to sneeze at for a company focused mainly on fuel distribution and refining. Its P/E ratio is 23.58, slightly lower than Santos, and its dividend yield is 3.69%. The latest EPS is $0.134, with a dividend per share of $0.15. Franking is a standout point here: every recent dividend is fully franked, which increases their appealing yield for local investors. Viva shares have also soared this year, posting a massive year-to-date return of 59.8%.
Dividend history is solid, with consistent, fully franked payouts across both interim and final periods. According to its current public description, Viva is buying into energy transition themes, including hydrogen and EV charging opportunities, though again, specific revenue figures weren’t available for this piece.
Valuation comparison
There are some clear differences between these energy stocks in both scale and capital structureâwhich can matter depending on what you’re after as an investor.
| Metric | Santos | Viva Energy |
|---|---|---|
| Market Cap | $27.77 billion | $5.26 billion |
| P/E Ratio | 26.58 | 23.58 |
| Dividend Yield | 3.66% | 3.69% |
| Dividend Franking | 0â6.6% (recent unfranked) | 100% fully franked |
| Earnings Per Share (EPS) | $0.225 | $0.134 |
| Dividend Per Share | $0.31 | $0.15 |
| YTD Return | 41.1% | 59.8% |
Note: Santos’ reported P/E ratio and EPS figures may reflect differences in accounting measurement (e.g. underlying vs. statutory earnings), so they might not correspond exactly.
Recent share price performance
Let’s compare both shares’ price action as of 24 September 2026:
- Santos closed at $8.55, gaining 1.79% for the day. Over the year to date, its shares are up 41.1%.
- Viva Energy closed at $3.20, rising 1.27% on the same day. Viva’s year-to-date return is a standout 59.8%.
These moves reflect a period of strength for both, but especially for Viva Energy, which has left most of the sector in its rear-view mirror.
Which is the better buy?
Both Santos and Viva Energy offer exposure to the backbone of Australia’s energy economy, but for me, the more compelling case is with Viva Energy right now. Here’s why: Viva’s shares have surged even further than Santos’s in 2026, but their P/E ratio is actually a touch lower, so investors aren’t paying up dramatically more for that growth. The dividend yields are virtually identical, but Viva’s dividends are fully frankedâwhich is a direct win for Aussie investors, as it means those payouts go further after tax.
On top of that, Viva is visibly leaning into the future of fuelâwhether it’s hydrogen, EV infrastructure, or importing natural gasâat a time when legacy oil and gas-focused models are facing longer-term questions. The company’s smaller market cap might mean less institutional following, but that can also present extra room for re-rating if execution continues.
Santos remains a cornerstone exposure with its global LNG and oil exposureâand it’s not a poor choice, especially for those seeking oil and gas project leverage. But purely on the numbers and strategy shown here, my pick would be Viva Energy for its franking advantage and stronger share momentum.
