S&P/ASX 200 Index (ASX: XJO) energy stock Ampol Ltd (ASX: ALD) is sinking today.
Shares in the Aussie fuel supplier closed on Friday trading for $28.98. In late morning trade on Monday, shares are swapping hands for $27.82 apiece, down 4.0%.
For some context, the ASX 200 is down 0.2% at this same time amid investor concerns over the new global tariffs proposed by United States President Donald Trump over the weekend.
Taking a step back, Ampol shares remain up 2% over the past 12 months, not including dividends. Ampol currently commands a market cap of around $6.6 billion.
Here's why the stock looks to be facing headwinds today.

ASX 200 energy stock drops on full year results
Investors are bidding down Ampol shares following the release of the company's full year results for the 2025 calendar year, despite some positive growth figures.
Highlights include a 20% year-on-year increase in replacement cost operating profit (RCOP) earnings before interest tax depreciation and amortisation (EBITDA) of $1.44 billion.
Management noted that in 2025 Ampol achieved earnings growth achieved across its Convenience Retail, Fuels and Infrastructure and New Zealand segments.
Turning to profits, RCOP net profit after tax (NPAT) leapt 83% to $429 million.
However, the ASX 200 energy stock could be catching headwinds today due to the company reporting a 33% year-on-year decline in statutory NPAT, which fell to $82.4 million in 2025.
On the passive income front, Ampol declared a fully franked final dividend of 60 cents per share. That's up 20% from the 2024 final dividend. At the current share price, that represents an instant yield of 2.2%.
If you want to bank the final Ampol dividend, you'll need to own shares at market close on 5 March. The ASX 200 energy stock trades ex-dividend on 6 March.
What did management say?
Commenting on the results, Ampol CEO and managing director Matt Halliday said:
The financial performance in 2025 is a high quality and broad-based result that reflects the steps taken in recent years to strengthen our delivery and increase our exposure to the more stable and growing business segments. The five-year compound annual growth rate of the combined EBIT from these businesses is about 11%.
Halliday added that this earnings growth includes the contribution of Ampol's acquisition of Z Energy.
With a look ahead, Ampol shares could also be under some pressure today with the ASX 200 energy stock noting that "global market uncertainty remains elevated amid geopolitical developments involving Iran, Venezuela and Russia/Ukraine".
Ampol concluded:
While it is too early to be conclusive on the implications, the integrated nature of Ampol's value chain means we are well placed to navigate changing conditions through our Trading and Shipping operations and the Lytton refinery to maintain supply for our customers.
