Highlights

  • Ampol Limited (ASX:ALD) reported unaudited replacement cost operating profit (RCOP) EBITDA of about A$1.6 billion for the six months to 30 June 2026.
  • Lytton refinery margins averaged US$28.26 a barrel in H1 FY26, compared with US$7.44 a barrel in the prior corresponding period.
  • EG Australia Acquisition expanded Ampol’s retail footprint with targeted annual synergies of A$65 million to A$80 million within two years.
  • Planned Lytton refinery maintenance from August to October 2026 is expected to reduce production by about 300 million litres.

Ampol reported unaudited replacement cost operating profit (RCOP) EBITDA of about A$1.6 billion for the six months to 30 June 2026 in a trading update released on 30 July, against A$649 million in the corresponding half of 2025. RCOP EBIT came in at roughly A$1.35 billion, versus A$404 million. Almost all of that improvement traces to a single asset. At the Lytton refinery in Brisbane, the Lytton Refiner Margin averaged US$28.26 a barrel across the half, against US$7.44 a barrel a year earlier. Audited accounts are due on 24 August. The backdrop is the closure of the Strait of Hormuz, which has reduced refined product availability in the Asian market Australia depends on and pushed cracks to elevated levels.

Company and market context

Ampol Limited (ASX:ALD) supplies and markets transport fuels across Australia and New Zealand and owns one of the country's two surviving oil refineries. Lytton, on the Brisbane River, has nameplate capacity of roughly 109,000 barrels a day and produced 5.5 billion litres in 2025. Around it sits a fuel and convenience business: a national retail network, a wholesale arm serving mining, aviation and transport customers, Import and storage infrastructure, and Z Energy in New Zealand. Smaller international operations include Gull and Seaoil in the Philippines.

Australia has retired most of its refining capacity over the past decade. Lytton and Viva Energy's Geelong plant are what remain, and between them they cover less than a fifth of domestic consumption. The balance arrives as finished product, mainly from refineries in Singapore, South Korea, Japan and China — the same plants whose Gulf crude feedstock must now find alternative routes around a disrupted waterway.

The latest catalyst

Two developments landed in quick succession. On 30 June Ampol Limited (ASX:ALD) completed the acquisition of EG Australia, the retail network Woolworths sold to Britain's EG Group in 2019, in a cash-settled deal of about A$1.1 billion. The Australian Competition and Consumer Commission cleared the transaction on condition that 41 sites be divested, and later approved Dib Group, trading as Metro Petroleum, as buyer of that package. Ampol has put the combined footprint at roughly 1,100 company-owned and operated sites nationally, with annual synergies of A$65 million to A$80 million targeted within two years.

The trading update followed on 30 July. Chief executive Matt Halliday said the conflict in the Middle East had created disruption across global energy markets, reinforcing the importance of liquid fuel Supply and domestic refining capability. Ampol also confirmed planned maintenance at Lytton from August to October, which it expects to reduce production by about 300 million litres.

What the numbers show

The June quarter did the heavy lifting. The Lytton Refiner Margin averaged US$30.93 a barrel in the second quarter against US$8.71 a barrel in the same quarter of 2025, an increase of 255 per cent. Refinery production for the half was 2,945 million litres, up 8.7 per cent year on year.

Volumes elsewhere grew more modestly. Australian fuel sales excluding net-sell reached 6,834 million litres, against 6,650 million litres, a gain of 2.8 per cent. Convenience Retail volumes rose 2.4 per cent to 1,778 million litres and Australian wholesale volumes 2.9 per cent to 5,056 million litres. Ampol secured roughly 250 million litres of fuel through an Export Finance Australia arrangement, while Z Energy secured about 90 million litres of diesel for New Zealand government inventory.

The base those figures are measured against matters. Ampol Limited (ASX:ALD)’s 2025 full-year result, released on 23 February 2026, showed RCOP EBIT of A$947 million and RCOP net profit after tax of A$429 million on Revenue of A$34.88 billion, with a fully Franked Dividend of 100 cents. Adjusted net Debt sat at about A$2.9 billion, or 2.3 times RCOP EBITDA. Lytton contributed A$163 million of EBIT that year, after a A$42 million loss in 2024.

Why investors are watching

The Investment case starts with refining asset scarcity. For most of the past decade the market treated Lytton as a capital-intensive asset attached to a fuel and convenience business. The recent supply disruption has highlighted the role of domestic refining capacity, while Earnings assumptions based on lower historical margins may not fully reflect the first-half margin environment.

The second strand is Capital returns. Ampol Limited (ASX:ALD) lifted its 2025 dividend 54 per cent to 100 cents fully franked, and the interim distribution on 24 August will provide further detail on how the board intends to allocate capital between shareholders, the Balance Sheet and integrating EG Australia. The retail and wholesale businesses also continued operating through the period, supporting earnings diversification.

What could drive the next move

The audited half-year result on 24 August is the near-term event, carrying the Interim Dividend decision and the first segment view including EG Australia. The Lytton maintenance programme runs to October, and the third-quarter update will show the production impact of that work and whether margins remained elevated while it was under way. The 41-site divestment and early synergy capture are the checkpoints on the acquisition. Above all, the status of the Strait of Hormuz sets the margin environment: a reopening, or a durable rerouting of Asian feedstock, would influence refining margins.

Risks

Concentration is the obvious one. A large share of group earnings now rests on one refinery running well through a margin environment influenced by geopolitical factors and market conditions. An unplanned outage at Lytton could affect earnings, while the August-to-October turnaround introduces execution risk during a period of elevated refining margins.

Volatile crude also affects Working Capital and widens the gap between RCOP and statutory profit, which in 2025 was the difference between A$429 million and A$82.4 million. Windfall refining earnings during a period of higher fuel prices can attract political attention. EG Australia adds integration risk and additional debt following the transaction. Longer term, electrification of light vehicles remains a structural headwind to fuel demand, and Z Energy is exposed to New Zealand economic conditions.

Outlook

Ampol Limited (ASX:ALD) enters the second half with a higher first-half earnings base, a larger retail network following the EG Australia acquisition and a refinery scheduled for planned maintenance. Attention on 24 August will centre on the interim dividend, the balance sheet following the EG payment, and management commentary on refining margin sustainability. Beyond that, the key external Factor remains global fuel supply conditions, including whether shipping routes normalise and how quickly international refining capacity adjusts.
