What has pushed Ampol shares to a multi-year high?
Ampol's shares have been driven higher by a combination of volatile global oil supply and company growth, including improved production and profit.
The company is Australia's largest transport energy distributor and retailer, with more than 1,800 Ampol-branded service stations across the country.
Unsurprisingly, its shares have rocketed higher on the back of conflict in the Middle East and concerns about global oil supply.
Ampol shares have jumped 37% higher since the war between the US and Iran ramped up in late February.
The shares suffered a temporary lull towards the back end of June when it looked like the two nations had reached a peace deal. Even so, the ceasefire was unstable, and even though the Strait of Hormuz partially reopened, supply continued to be very constrained and unpredictable.
But Ampol shares rocketed higher again this morning as the peace talks fell apart in early July and the region descended into war again.
According to Trading Economics, the price of WTI crude oil has also surged higher this month, and is trading over the US$83 per barrel mark at the time of writing.
There is still some way to go before the price returns to the US$113 per barrel level seen in April, but it is still significantly higher than the US$60 per barrel levels seen earlier this year.
Prices for Brent oil, gasoline, heating oil, and Ethanol have also jumped higher over the past month.
It's not only oil supply and prices supporting this year's share price rise.
Ampol has also posted a few updates that have gathered investor attention. In June, Ampol received the green light, with conditions, from the Australian Competition and Consumer Commission (ACCC) for a proposed acquisition of fuel and convenience store operator EG Australia.
The company previously confirmed a 10% increase in refinery production, higher refiner margins, and increased production in its Q1 FY26 trading update.
