Ampol (ASX:ALD) Q1 refiner margin quadruples to US$25.45 as Hormuz squeezes supply

Ampol Shares Jump on Lytton Margin Surge

Ampol (ASX:ALD) shares jumped 3.76% to A$32.80 on Wednesday after the fuel giant delivered a standout quarterly update. The headline was hard to miss: the Lytton Refiner Margin surged to US$25.45 per barrel in the March quarter, more than four times the US$6.07 reported a year ago. The driver is the Middle East crisis and disruptions through the Strait of Hormuz, which have squeezed the global fuel supply. For investors, the real question is no longer whether Ampol had a great quarter but how long these bumper margins can actually last.

Why Lytton Is Winning While Other Refiners Struggle

Ampol is Australia’s only locally listed fuel refiner, and its Lytton plant in Brisbane is doing the heavy lifting right now. The refinery uses a lighter, sweeter type of crude than most Persian Gulf plants, which means it has been largely shielded from the Middle East supply shock. In simple terms, when global fuel supply gets tight, Ampol is one of the few refiners that can keep running smoothly and sell fuel at much higher prices.

What we like here is the planning. Management saw the tension building early and locked in crude and product supplies before things got worse. Diesel and jet fuel are now secured through to the end of May, with petrol supplies covered to the end of June. That is the kind of move that separates a good operator from a lucky one.

Production and Demand Are Both Moving in the Right Direction

The operational side also looks healthy. Total refinery production rose 10% to 1.434 billion litres as earlier weather problems faded. Pump demand in Australia has held up nicely too, with convenience store volumes up 3.5% and wholesale volumes up 5.2%. In our view, this tells us drivers and businesses are absorbing higher fuel prices without cutting back much, which is a good sign for the company’s retail arm.

In another smart move, Ampol has pushed the big Lytton maintenance shutdown back to August. That keeps the refinery running through this high-margin window. Every extra week of full production right now goes almost straight to the bottom line.

The Investor’s Takeaway

Ampol is clearly executing well, and it shows in the share price. The stock has climbed 45% over the past year, leaving the broader ASX 200’s 15% gain in its dust. The market cap now sits at around A$7.8 billion. Here is the catch. Much of this good news already looks priced in. The current sky-high margins depend on a tense geopolitical situation that can change quickly. For context, RBC Capital Markets was forecasting a full-year 2026 Lytton margin of just US$9.70 per barrel in late 2025, which shows how unusual today’s US$25.45 level really is.

Our view is that Ampol is a quality operator, but at current levels, investors need to be clear about what they are buying: a company riding an extraordinary refining window. Watching any progress on US-Iran peace talks and how Ampol handles the August turnaround will help answer whether there is more room to run or whether the easy money has already been made.
