Highlights

  • H1 replacement cost EBITDA is expected at AUD 770-780 mn, up from AUD 305 mn a year earlier.
  • The Geelong Refining Margin averaged US$21.1/bbl in the first half.
  • The refinery recovered to more than 90% capacity after an April fire.
  • Net Debt fell to AUD 1.7 bn from AUD 2.1 bn at the end of 2025.

Viva Energy Group (ASX:VEA) has moved from outage concerns to an unusually strong refining Earnings period. Despite an April fire at Geelong, regional product shortages lifted the refining margin to US$21.1 a barrel across the first half, driving replacement cost EBITDA guidance to AUD 770-780 mn. The refinery also returned above 90% capacity before period end and net debt fell. The issue now is durability.

Recent Developments

The half did not begin well. On 15 April a fire broke out in the alkylation unit within the refinery's gasoline complex. No injuries were reported and crews extinguished the blaze the following morning. Crude distillation and the reformer were unaffected, but petrol production fell to about 60 per cent of normal and diesel and jet fuel to about 80 per cent. Recovery ran ahead of guidance. The residue catalytic cracking unit restarted in June and the refinery returned to more than 90 per cent of capacity by the end of the half.

Why It Matters

The Investment case starts with operating leverage. The case centres on a Business carrying fixed refinery costs converts each extra dollar of margin almost entirely into EBITDA, which is why a US$12.9 a barrel improvement in the Geelong margin produced a near two-and-a-half-fold lift in group earnings. They also point to AUD 400 million of debt reduction in one half, restoring headroom consumed by the OTR acquisition.

Revenue will show how operating progress converts into scale.

Cash Flow remains central to funding flexibility and balance-sheet strength.

Free Cash Flow will determine how much operating progress reaches the balance sheet.

Capital Expenditure remains a key consideration through the next growth phase.

Company Overview

Viva Energy runs three businesses. Energy & Infrastructure is built around the Geelong refinery in Victoria, which supplies roughly 10 per cent of Australia's fuel. Commercial & Industrial sells fuel and lubricants to mining, transport, aviation and marine customers and operates terminals and pipelines. Convenience & Mobility covers the retail network: about 900 company-operated sites under the OTR, Reddy Express and Shell brands, plus supply into roughly 1,300 dealer-operated service stations.

Financial Snapshot

Figures below are for the six months to 30 June 2026 on an unaudited, replacement cost basis, as disclosed on 28 July. Energy & Infrastructure delivered EBITDA of about AUD 353 million. Crude intake at Geelong was 19.7 million barrels, up from 18.8 million despite the fire. With the realised margin well above the AUD 15.9 a barrel trigger, no Fuel Security Service Payment was received from the Commonwealth. Commercial & Industrial contributed roughly AUD 305 million on sales of 5,865 million litres, about 1.0 per cent above the 5,804 million litres a year earlier, helped by resources Demand and marine spot sales.

What to Watch

The audited half-year result on 24 August is the near-term event. It will confirm the trading update, break out segment detail and carry the board's Interim Dividend decision — the first real test of whether the deleveraging is shared with shareholders. Beyond that, the second-half refining margin is the swing factor, and the sell side is not aligned on it.

Risks

The central risk is that the earnings driving the re-rating are borrowed from geopolitics. Refining margins are cyclical and Viva Energy does not control them. A de-escalation in the Middle East that restores product flows would compress the Geelong margin quickly, and the Fuel Security Service Payment cushions the downside below AUD 15.9 a barrel rather than protecting current levels. Asset concentration compounds that.

What Could Test Viva Energy's Refining Upswing

The half was exceptional and the market has repriced the stock accordingly, from a June low of AUD 1.96 to a 52-week high inside six weeks. The question the 24 August result must begin to answer is how much of that AUD 770 million to AUD 780 million is repeatable.
