Key Takeaways

  • Viva Energy Group (ASX: VEA) expects group EBITDA on a replacement cost basis of $770 million to $780 million for the six months to 30 June 2026, against $305 million in the prior corresponding half.
  • The Geelong Refining Margin averaged US$20.1 a barrel across the half, up from US$8.5 a barrel a year earlier, with the June quarter alone at US$21.1 a barrel.
  • Net debt fell to roughly $1.7 billion at 30 June 2026 from $2.1 billion at the end of 2025. Audited first-half accounts are scheduled for 25 August 2026.

Why Viva Energy is in focus

The unaudited first-half update lodged with the ASX on 27 July 2026 changes the arithmetic. Viva Energy Group (ASX: VEA) now expects group EBITDA on a replacement cost basis of between $770 million and $780 million for the six months to 30 June 2026 - more than its entire 2025 financial year result of $700.9 million and roughly two and a half times the $305 million earned in the corresponding half of 2025.

The cause sits well outside Viva's control. Conflict in the Middle East disrupted crude flows and, more importantly for a refiner, took refining capacity offline across the Gulf. Regional product cracks widened sharply. Viva, which owns the Geelong refinery in Victoria, was positioned to capture it.

What the company actually told the market

The announcement is a trading update and unaudited result, not a full set of accounts. Viva has been careful to label it as such and the audited first-half figures are due on 25 August 2026. Investors should treat the EBITDA range as a guide that could shift once auditors and the final replacement-cost adjustments are applied.

Within the range, the segment split is instructive. Energy and Infrastructure, the division that houses the Geelong refinery, contributed roughly $353 million. Commercial and Industrial, which supplies mining, aviation, transport and marine customers, contributed about $305 million. Convenience and Mobility, the retail arm, contributed approximately $138 million.

Chief executive Scott Wyatt described the half as one "shaped by geo-political events which have caused significant disruption across the global energy markets" - an unusually direct acknowledgement that the result reflects external conditions rather than internal improvement.

Where the margin came from

The Geelong Refining Margin, Viva's headline measure of refining profitability, averaged US$20.1 a barrel across the first half, against US$8.5 a barrel in the same period of 2025. The June quarter was stronger still at US$21.1 a barrel, compared with US$8.2 a barrel in the June quarter of 2025.

Refining intake for the half was 19.7 million barrels, but the split reveals a constraint: 10.2 million barrels in the March quarter and only 9.5 million in the June quarter. Sales volumes held up, with Convenience and Mobility fuel of 2,625 million litres, Commercial and Industrial fuel of 5,865 million litres and total group sales of 8,490 million litres.

The fire that complicated the half

On the evening of 15 April 2026 a fire broke out in the alkylation unit within Geelong's gasoline complex. Petrol output dropped to roughly 60 per cent of normal capacity and diesel and jet fuel to about 80 per cent. By the time of the July update the refinery had returned to more than 90 per cent. The timing was unfortunate: the fire constrained throughput during precisely the quarter when margins were widest. Any insurance recovery has not been quantified.

Strategic significance

Viva's investment case has been built on the argument that refining volatility would matter less over time as convenience retail and commercial fuels grew. This half undercuts that narrative in an awkward way. It demonstrates that refining remains capable of dominating group earnings when conditions turn, which is a double-edged observation: the same operating leverage that produced $353 million in six months can vanish just as quickly.

There is a policy dimension. Geelong is one of only two operating refineries left in Australia and the Commonwealth's Fuel Security Services Payment, enhanced in March 2026, provides support when the refining margin marker falls below a threshold. In a half like this one it pays nothing, but it remains a floor under the downside.

Growth drivers beyond the cycle

The structural work continues regardless. Viva is converting former Coles Express sites to the OTR brand, a program it argues lifts shop sales per site and Convenience and Mobility's $138 million contribution suggests retail is recovering from a difficult 2025. The Geelong energy hub, including a gas import terminal, is a longer-dated infrastructure option, while Commercial and Industrial is a defensive annuity tied to mining and aviation rather than crack spreads.

Balance sheet and capital

Cash generation has repaired the balance sheet quickly. Net debt fell to approximately $1.7 billion at 30 June 2026, from $2.1 billion at 31 December 2025. Viva ended 2025 with gearing around three times net debt to EBITDA and a stated ambition of about two times by the end of 2027; a half like this accelerates that materially.

Capital expenditure guidance for 2026 was set at roughly $350 million to $400 million, down from $494.4 million in 2025. The 2025 full-year dividend was 6.77 cents per share fully franked. The July update did not address the interim dividend, which will be decided with the audited accounts. With gearing falling and cash building, the capital-management question is live.

Principal risks

The dominant risk is that the margin environment normalises. Crude fell sharply in late July 2026 as Washington paused strikes and negotiators worked on reopening shipping through the Strait of Hormuz. Refining margins that widened on supply disruption can compress on the same news and Viva does not control the timing.

Operational reliability is the second risk. The April fire showed how a single unit outage removes a meaningful share of output. Third, the convenience business faces persistent competition and a declining tobacco category. Fourth, the energy transition remains a structural headwind for a fuels-weighted business. Finally, this is an unaudited update; the final numbers may differ.

A balanced outlook

Viva Energy has had a very good six months for reasons that have little to do with management execution and a great deal to do with a war. That does not make the cash less real and a balance sheet repaired by $400 million in one half is a durable benefit even if margins revert.

The question for investors is what multiple to apply to earnings this cyclical. Buyers are arguing that refining scarcity is structural and that the retail turnaround is finally taking hold. Sellers are arguing that US$20 a barrel margins are a spike, not a level. The audited accounts on 25 August will inform that debate rather than settle it.
