Viva Energy (ASX: VEA) 1H26: EBITDA jumps to A$780m as Geelong refining margins surge

Viva Energy Group Limited (ASX: VEA) has posted a 1H26 trading update showing unaudited Group EBITDA (RC) of approximately A$770 to A$780 million for the six months to 30 June 2026, more than two-and-a-half times the A$305 million reported in 1H25 and above the entire A$701 million EBITDA the company delivered across FY25. The result is anchored by a Geelong Refining Margin of US$21.1 per barrel, up from US$8.2 in the prior corresponding period, reflecting a regional refined-products shortage triggered by disruption to Middle East oil flows. Net debt has fallen to approximately A$1.7 billion from A$2.1 billion at the end of December 2025, a rare balance-sheet move for a domestic refiner in a single half. The central tension for investors is not the headline number itself, but how much of it is a windfall tied to geopolitics, hedging arrangements struck before the conflict and a temporary refining bottleneck, and how much reflects a durable earnings step-up in the retail and commercial businesses.

How did geopolitical disruption in the Middle East reshape the Geelong Refinery’s earnings in 1H26?

The most consequential number in the trading update is not the EBITDA line, it is the Geelong Refining Margin. At US$21.1 per barrel across the half and US$20.1 per barrel in the second quarter, GRM is running at more than double the long-term average and roughly 2.5 times the level reported for 1H25. Management attributes this to disruption of oil flows from the Middle East, which reduced production and availability of refined products at a regional level, tightening the Singapore-parity pricing environment that anchors Geelong’s economics. Because the Fuel Security Services Payment mechanism only activates when the Margin Marker sits below A$15.9 per barrel, no FSSP was received in 1H26, which is itself a signal of how far above the safety net the market has traded.

The Energy and Infrastructure segment produced approximately A$353 million of EBITDA, up from a low base and now the single largest contributor to the group. Refining intake for the half was 19.7 million barrels, an increase of 4.5 percent versus 1H25, meaning the company captured the elevated margin across a higher throughput than a year earlier. Management has stated that regional refining margins are expected to remain above long-term averages through the remainder of FY26, but that guidance is conditional on the current supply picture holding, and the company has not attempted to quantify how the margin might normalise if Middle East flows recover.

Why does the Alkylation unit fire at Geelong still matter for the shape of the 2H26 result?

On 15 April 2026, a fire in the Alkylation unit at the Geelong Refinery disrupted operations, and the site’s Residue Catalytic Cracking Unit and associated units only restarted in June. Management has confirmed that production has now returned to over 90 percent of normal capacity, but it has not disclosed the full financial impact of the incident, nor whether the remaining shortfall represents a residual constraint or a deliberate operating choice.

The commercial significance is that the 1H26 refining result was achieved despite this outage. If the alkylation unit and associated ancillary systems return to full contribution during the second half, and if regional margins remain elevated, refining earnings could rise from an already high base, although foreign-exchange translation, crude differentials and product-slate mix will all influence the actual outcome. Conversely, any recurrence of unplanned downtime would remove the natural buffer the company currently enjoys and would leave management more exposed to a margin normalisation than the trading update alone suggests.

What does the Commercial & Industrial hedging tailwind mean for the 2H26 earnings trajectory?

The Commercial and Industrial segment delivered approximately A$305 million of EBITDA on volumes that grew only 1.0 percent for the half. That volume growth is respectable but modest, and it makes clear that the segment’s earnings were not driven by underlying demand strength. Management has explicitly stated that C&I benefited from favourable hedging and term supply arrangements that were in place prior to the Middle East conflict, and that these arrangements are expected to be less supportive through 2H26.

That admission is the single most important forward-looking sentence in the trading update. It signals that a portion of the C&I windfall is a timing effect rather than a repeatable operating condition. The segment includes the resource sector, marine, aviation and other bulk fuels, and volumes in 2Q26 actually declined 4.7 percent versus 2Q25 because of a pull-forward of demand into 1Q26 and disruption to aviation fuel demand tied to the same Middle East conflict that lifted refining margins. The read-through is that the C&I earnings profile in 2H26 will depend more on physical volumes and spot supply economics than on the hedging structure that carried the first half, and investors modelling a straight-line extrapolation of 1H26 into a full-year number are likely to overstate the run-rate.

Is the Convenience & Mobility improvement a genuine retail turn or a fuel-margin echo?

The Convenience and Mobility segment produced approximately A$138 million of EBITDA, with fuel volumes up 2.4 percent for the half and 4.0 percent in 2Q26. Retail fuel margins were described as robust across most of 1H26, and stronger fuel sales pulled through slightly higher customer visits, which in turn supported non-fuel activity. Convenience sales excluding tobacco rose 1.3 percent, aided by expansion of third-party delivery arrangements with Uber Eats and DoorDash across the store network.

That 1.3 percent figure deserves attention. It is the cleanest available proxy for the underlying retail turnaround the market has been waiting for, and it is far below the growth rates typically expected from a business in the middle of a store-conversion programme with a new loyalty proposition. Tobacco sales fell 16.8 percent versus the prior period, although management notes that tobacco is stable versus 2H25, suggesting the category has found a lower plateau rather than continuing to decline. Convenience gross margin held at 37.7 percent for the half, but the 2Q26 number was affected by approximately A$6 million of inventory write-downs, without which margin would have been broadly in line with 2Q25. The retail story is therefore progressing, but it is progressing slowly, and the segment’s headline improvement owes as much to fuel economics as to a step-change in the convenience proposition.

How significant is the reduction in net debt for the investment case?

Net debt of approximately A$1.7 billion at 30 June 2026, down from A$2.1 billion six months earlier, represents a meaningful step forward for a company that has historically carried elevated leverage relative to its cash generation. The company describes this as being driven primarily by strong conversion of earnings to cash, which is consistent with the sharp uplift in refining and C&I profitability across the half. Management guided at the FY25 result to lower capital expenditure of A$350 to A$400 million for FY26, and completing the multi-year Ultra-Low Sulphur Gasoline investment programme has removed a significant call on cash. Combining that lower capex intensity with the current earnings environment gives the company an unusual window in which to deleverage.

The strategic question is what management does with the capacity created by this window. Options include accelerating store conversions, funding further tuck-in acquisitions, returning capital via dividends or buybacks, or building a genuine balance-sheet buffer before the next cyclical downturn in refining margins. The trading update does not commit to any of these paths, and the market response will depend on the choices signalled at the interim result on 24 August 2026.

What do the OTR integration milestones and the Coles PSA exit reveal about execution?

The 1H26 update contains several operational data points that are more strategically significant than the headline numbers suggest. The company confirmed that it remains on track to complete the rollout of new convenience supply distribution centres and to exit the Coles Product Supply Agreement by the end of FY26. Ending the Coles PSA is a structural event because it removes a legacy arrangement that has constrained margin economics across a large share of the retail network for years. Distribution centres in Victoria and Queensland are now established, with New South Wales expected to be operational shortly.

The company also extended the FlyBuys loyalty programme to the OTR branded network during 2Q26, giving it a uniform loyalty offer across its Shell-branded company-owned network for the first time. Management has updated network development plans to reflect current project delivery expectations, and now expects approximately 20 to 25 new OTR store openings in FY26, 10 to 15 Reddy Express conversions to a mix of OTR and Liberty Convenience formats, and 25 to 30 store conversions to an unattended self-service format following successful trials. The reduction in the Express network from 669 to 635 sites, alongside the growth of OTR to 251 sites and Liberty Convenience to 97 sites, reflects a deliberate reshaping of the retail portfolio rather than an unplanned drift. The core fuel and convenience network of 983 stores is essentially unchanged versus a year earlier, so the value creation must come from mix change and format upgrades rather than footprint growth.

What would strengthen or weaken the investment thesis into the 24 August result?

The 1H26 trading update sets a high bar for the interim result on 24 August 2026 to convert a windfall into a durable narrative. Strengthening evidence would include a further reduction in net debt without a corresponding lift in working capital, confirmation that refining intake in 2H26 can absorb full alkylation-unit contribution, a lift in non-tobacco convenience growth above the 1.3 percent posted in 1H26, and a capital-return signal calibrated against the deleveraging trajectory. Weakening evidence would include a rapid retreat in the Geelong Refining Margin from current levels, a widening of the hedging fade in C&I that management has flagged, slippage in the Coles PSA exit timetable, or any additional operational incident at Geelong that limits the second-half production recovery.

For a stock trading in a range that has priced in a partial recovery narrative for much of 2026, and with analyst consensus twelve-month price targets clustered around A$2.58 to A$2.77, the trading update strengthens the near-term earnings picture but does not yet resolve the medium-term question of what a normalised refining margin looks like once the Middle East disruption fades.

Viva Energy 1H26 key takeaways: refining windfall, hedging fade and the A$1.7bn deleveraging test

• Viva Energy 1H26 unaudited Group EBITDA (RC) is expected at approximately A$770 to A$780 million, more than double 1H25 and above the full FY25 result of A$701 million.
• Geelong Refining Margin lifted to US$21.1 per barrel, well above long-term averages, driven by Middle East supply disruption and regional refined-products tightness.
• No Fuel Security Services Payment was received in 1H26 because the Margin Marker averaged above A$15.9 per barrel, confirming the market traded well clear of the government floor.
• The Alkylation unit fire on 15 April 2026 constrained production, with capacity now restored to over 90 percent, leaving upside if full recovery lands in 2H26.
• Commercial and Industrial EBITDA of approximately A$305 million was supported by pre-conflict hedging and term supply arrangements that management explicitly expects to be less supportive in 2H26.
• Convenience and Mobility EBITDA of approximately A$138 million was aided by fuel-volume growth of 2.4 percent, but underlying non-tobacco convenience sales grew only 1.3 percent.
• Net debt fell to approximately A$1.7 billion from A$2.1 billion at 31 December 2025, driven by strong earnings conversion into cash.
• The company remains on track to exit the Coles Product Supply Agreement by end of FY26 and to open 20 to 25 new OTR stores, alongside 10 to 15 Reddy Express conversions.
• The FlyBuys loyalty programme was extended to the OTR branded network during 2Q26, giving a uniform loyalty offer across the Shell branded company-owned network.
• The interim result on 24 August 2026 will need to show capital-return discipline, retail traction beyond fuel economics, and a credible base for refining once geopolitical margins normalise.
