Key Highlights

• Design reviews at the 30% stage are finished for both the extraction and chemicals plants, with 60% reviews next.

• The Lionheart package totals €2.2 billion, comprising strategic Equity and debt, with financial close reported in the second quarter of 2026 and earlier coverage dating the package's announcement to December 2025.

• Foreign-exchange exposure also matters, since Vulcan reports in euros and the Quartr summary noted a €12.7 million foreign-exchange loss in the half.

• With a €2.2 billion funding package at financial close, the questions have shifted from whether the project can be financed to whether it can be built on time and in budget.

How far has Vulcan Energy Resources Ltd. (ASX:VUL) moved from lithium developer to builder? The company's Quarterly Report for the period ending 30 September 2026 says its Lionheart project in Germany is "progressing on schedule and within budget", with first production targeted for 2028. With a €2.2 billion funding package at financial close, the questions have shifted from whether the project can be financed to whether it can be built on time and in budget.

The central development

According to the quarterly report, early earthworks and the relocation of a 110kV power line at the lithium extraction plant site are complete, and civil works have begun at the site of the 30MW geothermal plant. Design reviews at the 30% stage are finished for both the extraction and chemicals plants, with 60% reviews next. Production of VULSORB adsorbent, the material used to capture lithium from brine, has started for the first Fill of the extraction columns. A re-injection well, LSC-3a, showed about 64 litres per second of injection capacity against an assumption of about 40 litres per second, a favourable technical data point for the geothermal side of the project.

The company's timeline lists further milestones for the fourth quarter of 2026, including completion of the Trappelberg well pad, mobilisation of a drilling rig, awards of construction contracts and restart of the Insheim power plant, and completion of ICPP Section 1 in the third quarter of 2027. Lionheart first production and commissioning are targeted for 2028. These are company targets, not outcomes.

Business model and Commodity exposure

Vulcan's primary commodity is lithium, specifically lithium hydroxide, a chemical used in lithium-ion batteries. It also sells renewable electricity and heat from geothermal energy. Its stated aim is to produce lithium with a lower carbon footprint than many conventional sources, and the integrated geothermal-plus-lithium model is designed to use the heat and power from the brine to run the process. The geothermal power and heat contribute separately to revenue.

Revenue so far is small. For the half-year to 30 June 2026, a Quartr AI-generated summary reported Revenue of €2.3 million, mainly electricity sales, a net loss after tax of €51.8 million (versus €30.7 million a year earlier) and Capital Expenditure outflows of €168.0 million, mostly on Lionheart. The key point is that Vulcan will remain pre-revenue in lithium until 2028 or later and will depend on financing until then.

Funding

The Lionheart package totals €2.2 billion, comprising strategic equity and debt, with financial close reported in the second quarter of 2026 and earlier coverage dating the package's announcement to December 2025. In the September quarter, Vulcan received €53.7 million of strategic equity drawdowns and €10.7 million of German grant payments. Further equity instalments are expected until the first Debt drawdown, scheduled for the first quarter of 2027.

Cash and deposits accessible after 90 days stood at €209.4 million at 30 September 2026 (€129.4 million in cash plus €80.0 million in longer-dated term deposits). Development spend in the quarter was €88.8 million. The Quartr summary reported €273.9 million at 30 June 2026, down from €517.8 million in December 2025, so cash is being drawn down as construction proceeds. This is normal for a build, but it makes the timing of equity and debt drawdowns important.

Sector and competitive position

Lithium prices were weak for much of the period after the 2022 peak, and the pace of electric-vehicle adoption in Europe affects Demand for battery chemicals. The European Union is seeking to build domestic Supply of battery materials, which supports projects like Lionheart, and Vulcan's location near German automotive and battery customers is an advantage. Competition includes Australian and South American hard-rock and brine producers and Chinese converters, which dominate chemical processing.

Risks and what to monitor

Key risks include construction cost overruns and delays; first-of-a-kind technology risk in integrating geothermal extraction with lithium chemicals production; lithium price risk; and the execution of the remaining financing drawdowns. Permitting is a specific risk: the quarterly report says a French court decision went against a geothermal permit for the Kachelhoffa project, and both that decision and a lithium permit validation are subject to appeal. Some exploration licences are due to expire in December 2026. Future phases, including Project Ludwig, have no Investment decision until Lionheart operates successfully. Foreign-exchange exposure also matters, since Vulcan reports in euros and the Quartr summary noted a €12.7 million foreign-exchange loss in the half.

Dates to monitor include the fourth quarter 2026 milestones listed above, the first debt drawdown in the first quarter of 2027, the December 2026 licence expiries, the December 2026 quarterly report, and completion of ICPP Section 1 in the third quarter of 2027.

In short, Vulcan is in the build phase with early technical results ahead of assumptions, but with several years of spending, permitting and commissioning risk before lithium revenue starts.
