ASX Announcement 08 September 2025 ORIGIN ENERGY LONG TERM BIOMETHANE OFFTAKE FOR DELOREAN SA1 SALISBURY BIOENERGY Delorean Corporation Limited (ASX: DEL) (“Delorean” or “the Company”) is pleased to announce that it has completed a binding Gas Sales Agreement with Origin Energy Retail Limited (“Origin”) for the long term supply of renewable biomethane from its SA1 Salisbury bioenergy facility in Edinburgh Parks, South Australia, with renewable gas delivered via the gas network. Under the agreement, Origin will purchase up to 200 terajoules per annum of biomethane ‘as arising’ from Delorean’s SA1 facility (currently under construction) on a take or pay basis for 8 years from expected first gas in April 2026 until March 2034, with a further two year option for Origin to March 2036. The renewable gas offtake agreement includes the purchase of Renewable Gas Guarantee of Origin (RGGO’s) which the SA1 facility will generate and can be used for the large industrial sector to reduce Scope 1 emissions in the hard to abate sector. Pricing for biomethane is escalated to CPI. Delorean’s biomethane offtake agreement with Origin Energy satisfies a key condition precedent for progressive payments up to $6.1m in Australian Renewable Energy Agency (ARENA) grant funding as part of ARENA’s National Industrial Transformation Program as announced to ASX on 6th March 2025, with first milestone payment of $2.7m expected in October 2025. This transaction, which operates under an existing Master Bilateral Gas Sales Agreement between Origin and Delorean, locks in $30-40m in revenue over the 10 year term (factoring in CPI escalations and the 2 year extension). Key conditions precedent to the Gas Sales Agreement are: • • • • Delorean has commenced commissioning of its SA1 Salisbury project; Delorean has obtained all approvals required for the operation of SA1, for Origin to receive biomethane at the gas network injection point, and to permit the injection of the biomethane into the Short Term Trading Market (STTM); Gas network provider Australian Gas Infrastructure Group has completed the construction of, and commissioned the gas network connection and installed all metering equipment at the delivery point so as to allow Delorean to deliver and Origin to receive Gas at the Delivery Point for injection into the STTM; and Origin has obtained all approvals required to receive biomethane at the delivery point for injection into the STTM.

In Stage 2 (future expansion), there is the potential for extension to 125,000 tonnes per annum under the current development approval. The SA1 Project will produce 6 different products and revenue streams, including Renewable Natural Gas (Biogenic Methane), renewable food grade liquid CO2 (Biogenic LCO2), Carbon Credits (ACCUs), Renewable Gas Guarantees of Origin (RGGOs), Liquid Fertilisers and Gate Fees.
