Viva Energy Group Limited

The Business

Viva Energy runs Australia's second-largest integrated fuel business: refining crude at Geelong, distributing fuel through a national terminal network, and retailing via roughly 1,400 service stations under the Shell brand. Commercial & Industrial (C&I) supply, covering aviation, marine, and bulk fuel contracts, generated $17.2 billion of FY25 revenue, versus $13.0 billion from Convenience & Mobility (C&M) retail and non-fuel sales. A third segment, Energy & Infrastructure, houses the refinery itself. Together with Ampol, Viva Energy controls roughly 60% of Australian fuel distribution, a duopoly built on physical infrastructure rather than regulatory protection.

Recent Performance

Viva Energy's shares have run hard over the past year as Middle East supply disruptions pushed refining margins to roughly US$21 a barrel in the first half of 2026, more than double the historical average. That windfall is set to lift FY26 EBITDA to an estimated $1.4 billion, up from $710 million in FY25, a doubling that reflects one commodity input rather than operational improvement. The market has re-rated the stock on the assumption that this margin strength persists.

Outlook

Our analysis assumes refining margins normalise over the next two years, unwinding much of the FY26 windfall as Middle East supply pressures ease. On that basis, EBITDA is forecast to decline materially over FY27 and FY28, with margins compressing back toward the low single digits from the FY26 peak. Earnings per share follow the same path, falling sharply in FY27 and again in FY28, a trajectory that looks dramatic in isolation but reflects the unwind of a temporary windfall rather than a business in structural decline. The swing factor is whether Convenience & Mobility can offset this decline; same-store sales are currently running at negative 3.8%, with a supply chain overhaul due by November 2026.

Key Risks

The dominant risk is refining margin reversion. We regard a normalisation toward historical margin levels as more likely than not, a shift that would materially reduce refining earnings from the current cycle peak and could pressure the balance sheet if it happens faster than the market expects. Convenience retail could disappoint further: same-store sales are already negative, and any additional deterioration risks a further write-down against a balance sheet where goodwill already represents 95% of shareholder equity. Total debt of $5.3 billion, including leases, adds a further layer of risk, since a sustained earnings downturn would bring the business closer to its covenant thresholds.

What to Watch

The thesis-defining event is the FY26 full-year result in Q4 2026, which will confirm whether the extraordinary first-half refining margin was a peak or a new normal. Beyond that, Strait of Hormuz shipping data is the clearest real-time signal, and government confirmation of the next phase of fuel security support would help quantify the earnings floor the business can rely on at trough margins.

• Q4 2026 FY26 full-year results — confirms whether the peak refining margin was transient or the start of a new range; mixed impact expected either way.
• Ongoing, 12-24mo Strait of Hormuz transit recovery — a sustained recovery in shipping volumes would confirm margin reversion is underway, negative for the stock.
• Q1 2027 FSSP Phase 2 government announcement — would clarify the earnings floor Viva Energy receives from fuel security support, positive for the downside case.

Latest Developments

Viva Energy reported first-half 2026 results in August, with refining margins of roughly US$21 a barrel and a $355 million reduction in net debt. Management flagged moderating Commercial & Industrial volumes into the second half and made no claim that the current margin strength is structural.

Company Description

Viva Energy operates three segments. Convenience & Mobility (C&M) runs roughly 1,400 Shell-branded service stations and convenience stores, generating $13.0 billion of FY25 revenue split between fuel and non-fuel sales. Commercial & Industrial (C&I) supplies aviation, marine, and bulk commercial customers directly, contributing $17.2 billion of FY25 revenue and the larger share of group turnover. Energy & Infrastructure operates the Geelong Refinery, Victoria's sole remaining oil refinery, converting crude into refined products for both the group's own distribution network and third-party sale. The refining segment is the smallest by revenue but the most volatile, since its earnings swing directly with the gap between crude costs and refined product prices.

Where the Growth Is

The clearest growth lever is the Convenience & Mobility transformation, a segment contributing roughly 30-35% of group earnings. Same-store sales are currently running at negative 3.8%, reflecting weaker discretionary spending at the till even as fuel volumes hold steady. Management has a supply chain and private label rollout targeted for completion in November 2026, designed to lift non-fuel margins and reverse the sales trend. Success would materially improve the earnings quality of the group's most controllable segment; failure, particularly if it triggers a further write-down against the segment's goodwill, would compound a balance sheet that already carries little tangible buffer.

Competitive Position

Viva Energy's competitive position rests on physical infrastructure that cannot be easily replicated. The Geelong Refinery is Victoria's only oil refinery, and no new refinery has been built in Australia in decades; construction costs and environmental approvals make new entrants effectively impossible. That scarcity is reinforced by federal fuel security policy, which explicitly funds the retention of domestic refining capacity and strengthens further during periods of supply disruption like the current Middle East conflict. Alongside Ampol, Viva Energy controls roughly 60% of Australian fuel distribution, a stable duopoly maintained by the cost of building competing terminal and pipeline networks rather than by regulation. This advantage is durable, likely to persist for five to seven years, but it is not expanding: convenience retail, the segment where genuine differentiation is possible, faces greater competitive pressure from supermarket-aligned and independent operators than the fuel business itself.

Management & Capital Discipline

Management has shifted capital allocation from acquisition-led growth toward deleveraging, cutting net debt by $355 million in the first half of 2026 alone. That shift makes sense given goodwill now represents 95% of shareholder equity, a balance sheet structure with limited tolerance for further impairment. On disclosure, management has been straightforward about near-term risks, flagging moderating Commercial & Industrial volumes and making no claim that current refining margins are structural. The more telling gap is what management has not said: no quantified targets have been given for the convenience-retail turnaround, despite it being the segment most within management's control. That silence, more than any stated risk, suggests internal uncertainty about how quickly the transformation can restore same-store sales growth.

Financial Position

Viva Energy's balance sheet is adequate but not strong. Total debt, including lease liabilities, sits near $5.3 billion, a heavy load against a business whose earnings can swing by hundreds of millions of dollars with the refining cycle. Covenant risk becomes material if EBITDA falls below roughly $860 million, a level our forecasts see the business approach by FY28. Liquidity is a genuine offset: $923 million of undrawn revolving credit facility provides headroom through a downturn. Capital efficiency is modest, with return on invested capital forecast to fall from 15% in FY26 to 8% in FY28 as the margin windfall fades.
