June 2026 Quarterly Activities — Released 30 July 2026

Quarterly sales revenue for the June 2026 quarter was $584,900, approximately 20% below the prior quarter revenue of $735,200. The reduction was attributable to lower gas production, with the Vali gas field contributing non-cash generating sales during the period. Production for the quarter was 0.05 PJe, down 17% from the prior quarter.

For the full year FY26, sales revenue was $3,006,100, down 35% from FY25's $4,659,700. Sales gas Volume was 0.23 PJ for FY26, down 39% from FY25. Unrestricted cash stood at $1.34 million at 30 June 2026.

The quarter's most significant development was the receipt of $5 million in South Australian government grants allocated to the Southern Flank Joint Ventures — Vintage's share of $2.5 million relates to the PRL 211 and ATP 2021 Joint Ventures (Vintage share 50%). These grants are reserved for the purpose of drilling the Odin-3 and Vali-4 gas production wells, planned for the 2027 financial year subject to JV approvals and rig availability. The grants represent approximately 50% of the estimated cost of drilling both wells.

An Entitlement Offer was completed during the quarter, closing after raising $1.35 million to provide Working Capital for ongoing operations. A Heads of Agreement with Vault Energy was executed, representing the first commercial agreement for the Cullen-1 asset in the Northern Territory, for gas from the well in the event of successful well testing. Managing Director Neil Gibbins noted that Cullen-1, with extensive gas and oil shows, is being reappraised as an enabling energy source for local mobile modular digital infrastructure.

Industry Context

Cooper Basin gas continues to be a strategically important source of domestic gas Supply for the eastern Australian market. The SA government's grant support for the drilling of new gas production wells reflects the broader policy emphasis on gas supply adequacy. The Cullen-1 asset in the Bonaparte Basin represents an emerging opportunity in the Northern Territory, where Demand for modular energy solutions supporting digital infrastructure is being assessed as a new end market for stranded gas assets. Vintage's FY26 production decline of 38% year-on-year to 0.24 PJe reflects the natural decline profile of the Vali and Odin fields without the Odin-3 and Vali-4 infill wells that are planned to reverse this trend.

Risks and Uncertainties

Vintage Energy's revenue and production declined materially in FY26, reflecting field decline and the absence of new production wells. The planned Odin-3 and Vali-4 wells are targeted for FY27, subject to joint venture approvals and rig availability, both of which introduce timing and execution risk. The company's cash position of $1.34 million at 30 June 2026 is modest, and the company relies on the SA government grants and any further capital raising to fund the drilling program. The Cullen-1 commercial agreement with Vault Energy is conditional on successful well testing, which has not yet occurred.
