Viva Energy's Refining Windfall Keeps Building, and Not Everyone Sees It

A geopolitically driven surge in refining margins and rapid debt reduction have fund managers debating how much of the good news is still to be priced in.

7 Oct 2026 · 4 min read

Viva Energy rallied more than 45 percent in a single month in March as the Iran conflict shut the Strait of Hormuz and sent Asian refining margins to record levels, and the stock has kept climbing since, with first-half profit up 482 percent year on year, as fund managers debate how much of the windfall reflects a temporary geopolitical spike versus a genuinely improved fuel security and industry structure.

A refinery security deal, then a geopolitical windfall

Pendal Group said the stock rose in March after Viva Energy reached agreement with the federal government to amend the terms of the Fuel Security Support Package, with revised terms better reflecting how refinery costs have evolved and back-testing suggesting support payments under the new framework would have been roughly double prior levels. Ellerston Capital said refining margins in Asia took off after the closure of the Strait of Hormuz, worsened by China suspending exports rather than drawing on its 90 to 120 day reserve, with Viva and Ampol, the only two remaining domestic refiners addressing around 20 percent of Australia's fuel demand, benefiting from gross refining margins spiking to record levels. Perennial Partners said the stock rallied 45.2 percent in March as energy became the standout sector, with the market materially re-rating earnings expectations for the Geelong refinery on top of the revised government fuel security settings. Paradice Investment Management added the stock in February on an undemanding valuation below 10 times forward earnings, asymmetric medium-term upside in the Refining and Mobile and Convenience divisions, and an irreplicable asset base.

A strategic scarcity value

Cadence Capital said Viva's first-half 2026 result captured substantially improved refining margins largely tied to the Middle East conflict, noting only two refineries remain in Australia today, down from seven fifteen years ago, underscoring the strategic nature of Viva's assets. Lennox Capital Partners, which does not hold the stock and counted missing it as its largest single detractor from relative returns, said the shares rose 38 percent to become the best performer in the ASX200 as renewed conflict drove Brent crude up 24 percent to around US$90 a barrel, compounding a strong June quarter in which Viva guided to first-half EBITDA around 10 percent ahead of consensus on strong fuel volumes.

A blowout result, mostly pre-announced

Pendal Group said Viva's quarterly update showed first-half FY26 guidance with Convenience and Mobility EBITDA and Commercial and Industrial EBITDA both roughly 30 percent above market, partly offset by Refining coming in about 10 percent light, for group EBITDA around 10 percent ahead of expectations, while net debt of $1.7 billion beat consensus by $100 million and prior expectations by $450 million. First-half profit rose 482 percent on the prior corresponding period, on similar dynamics to rival Ampol, with the result thoroughly pre-announced so there were no surprises at the headline level, though slightly higher depreciation led to a small 2 percent miss at the bottom line, while the dividend came in around 25 percent ahead of expectations. Firetrail Investments said the stock hit 12-month highs as refining margins rebounded on the reignited Iran conflict and increased Ukrainian strikes on Russian refinery output, with preliminary results beating consensus earnings by 10 percent and cutting net debt by $200 million versus forecast, a rapid de-gearing it argues the market has not yet fully credited.

What fund managers say they are watching next is whether Middle East-driven refining margins persist or normalise, whether the Refining division catches up after coming in below market guidance, continued balance sheet de-gearing that Firetrail believes remains under-appreciated, and whether the revised Fuel Security Support Package terms provide a more durable earnings floor going forward.
