Highlights

  • Viva Energy reported a significant improvement in first-half trading conditions, supported by a Geelong Refining Margin of approximately US$21.10 per barrel compared with around US$8.20 a year earlier.
  • Replacement-cost EBITDA was estimated at approximately A$770-A$780 million for the first half, significantly above the previous corresponding period.
  • Net debt reduced to around A$1.7 billion by 30 June 2026, supported by improved cash generation during the period.
  • The audited half-year result due on 24 August 2026 will provide further clarity on earnings, segment performance and dividend decisions.

Viva Energy Group Limited (ASX: VEA) has entered the second half of 2026 with improved operating momentum after a sharp increase in refining margins boosted expectations around earnings performance.

The company’s Geelong refinery has been the primary driver of recent improvement, benefiting from stronger regional refining conditions and supply disruptions. However, the sustainability of these elevated margins remains uncertain, as refining profitability is highly cyclical and influenced by global energy markets.

Favourable trading update driven by refining performance

On 28 July 2026, Viva Energy released an unaudited trading update for the six months ended 30 June 2026. The update showed replacement-cost EBITDA of approximately A$770-A$780 million, compared with around A$305 million in the prior corresponding period.

The company’s Geelong Refining Margin averaged approximately US$21.10 per barrel during the first half, compared with roughly US$8.20 per barrel a year earlier.

The improvement reflects stronger refining conditions, particularly wider product margins caused by regional supply constraints and shifting energy market dynamics.

Viva Energy also reported that net debt had reduced to approximately A$1.7 billion at 30 June 2026, compared with around A$2.1 billion at the end of 2025.

The company’s audited half-year results, scheduled for release on 24 August 2026, will confirm the trading update figures and provide further details on financial performance.

Refining remains the main earnings driver

The improvement in earnings has been largely driven by refining operations.

Refiners generate returns from the difference between crude oil input costs and the selling prices of refined products such as petrol, diesel and jet fuel. During the first half, this spread expanded significantly, supporting stronger profitability.

The improvement came despite operational disruption at the Geelong refinery following a fire incident in April 2026. The event temporarily affected production levels, reducing petrol output and limiting diesel and jet fuel production.

Production recovered progressively, with operations returning above 90% of normal levels by June.

The combination of stronger refining economics and operational recovery helped offset some disruption-related impacts. However, the exceptional margin environment remains dependent on external market conditions rather than being fully structural.

Energy market conditions remain influential

Global energy markets continue to play an important role in Viva Energy’s performance.

Refining margins have benefited from supply constraints and geopolitical uncertainty affecting regional fuel markets. However, higher crude oil prices alone do not determine refinery profitability, as earnings depend more directly on the difference between crude costs and refined product prices.

If supply conditions normalise or geopolitical pressures ease, refining margins could moderate from current elevated levels.

This creates uncertainty around how much of the recent earnings improvement can be sustained over the longer term.

Business diversification provides additional support

Beyond refining, Viva Energy operates across Commercial & Industrial, Convenience & Mobility, and Energy & Infrastructure segments.

The Convenience & Mobility division has been strengthened through the integration of the OTR Group and the earlier Coles Express network transition.

The company continues to focus on expanding its convenience retail presence and improving operational efficiency across its network.

Government support measures for domestic refining also provide additional downside protection by supporting fuel security objectives and improving resilience for local refining operations.

Growth drivers

Viva Energy’s growth outlook is supported by several factors.

The primary driver remains the performance of the Geelong refinery, where improved margins and increased operational stability could continue supporting earnings.

The company’s convenience network expansion provides another avenue for long-term growth, while its diversified operating model reduces reliance on a single business segment.

Further debt reduction through stronger cash generation could also improve financial flexibility over time.

Key risks

The biggest risk remains refining margin volatility.

The current earnings improvement has been supported by unusually favourable market conditions, which may not continue if global supply constraints ease.

Operational disruptions remain another consideration, as demonstrated by the Geelong refinery incident earlier in 2026.

The company’s debt levels, although reduced, remain an important factor, particularly if refining margins weaken.

Longer-term changes in fuel demand, including increased adoption of alternative energy sources, could also influence future growth opportunities.

Upcoming catalysts and dates

The main upcoming event is Viva Energy’s audited half-year result on 24 August 2026.

The announcement is expected to provide:

  • Confirmation of first-half earnings.
  • Detailed segment performance.
  • Updated balance-sheet information.
  • The board’s decision regarding the interim dividend.

Investors will also monitor refinery operating performance, fuel market conditions and global energy developments.

Balanced outlook

Viva Energy has delivered a strong operational update, with refining margins providing a significant boost to first-half performance.

The improvement in EBITDA expectations and reduction in net debt demonstrate stronger financial momentum. However, the current earnings environment remains closely linked to cyclical refining conditions and global energy markets.

The upcoming half-year results will be important in determining whether the recent improvement represents a temporary margin benefit or the beginning of a more sustained earnings recovery.
