Company Overview

Vulcan Energy Resources (ASX: VUL) is a lithium and renewable energy company that produces low-carbon lithium and geothermal energy from underground brine in Germany's Upper Rhine Valley.Founded in 2018 and originally named Koppar Resources before rebranding to Vulcan Energy Resources in September 2019, the company is headquartered in Perth, Western Australia, with Cristian Moreno serving as CEO. Vulcan operates through three main segments: Germany (its core operations base), Other Europe (France and Italy), and Australia, with the German segment generating the bulk of its activity.

We regard Vulcan Energy Resources as one of Europe’s most strategically positioned emerging lithium developers. The company’s Zero Carbon Lithium™ project in Germany is designed to produce both renewable geothermal energy and battery‑grade lithium hydroxide with a net‑zero carbon footprint — a proposition that directly aligns with Europe’s accelerating decarbonisation agenda and domestic battery supply chain requirements.

Recent operational updates, financing progress, and regulatory tailwinds reinforce our conviction that Vulcan is transitioning from a high‑concept story to a maturing development platform. While market sentiment has been volatile, we believe the company’s integrated geothermal‑lithium model remains structurally differentiated and underappreciated.

FY25–26 Performance: Strategic Progress and Operational Depth

Vulcan’s recent updates highlight disciplined execution across development, financing, and commercial partnerships. Vulcan continues to advance its Phase One development plan, aiming to deliver commercial production of lithium hydroxide and renewable geothermal energy from the Upper Rhine Valley. Recent operational progress has been broad‑based and meaningful. Drilling across the Phase One licence area has remained successful, consistently confirming high‑flow geothermal brine characteristics that support long‑term production assumptions. Engineering design work for both the lithium extraction plant and the geothermal power facilities has moved forward, strengthening the technical foundations of the Zero Carbon Lithium project. At the same time, the company has deepened its commercial partnerships with European automotive manufacturers seeking low‑carbon lithium supply, reinforcing demand visibility and strategic alignment with EU battery regulations. Permitting and environmental approvals have also advanced under Germany’s regulatory frameworks, bringing the project closer to full development readiness.

The company’s integrated model — geothermal energy + lithium extraction — remains unique in the global lithium sector and positions Vulcan as a potential cornerstone supplier for Europe’s battery ecosystem.

Strategic Execution: Zero Carbon Lithium™ Development Pathway

1. Phase One Development - Engineering and Approvals

Vulcan continues to advance the engineering design for its Phase One integrated geothermal–lithium facilities, laying the groundwork for commercial development. The plan encompasses the construction of geothermal wells and reinjection systems, which will form the backbone of the project’s energy and brine‑handling infrastructure. Alongside this, the company is developing a central lithium extraction plant that will utilise direct lithium extraction (DLE) technology to produce battery‑grade lithium hydroxide. Renewable energy generation will be integrated into the system to power operations and supply excess electricity to local grids, reinforcing the project’s zero‑carbon credentials. In parallel, Vulcan is working towards finalising permitting under German mining and environmental legislation, a critical step in moving the project toward full construction readiness.

The company’s recent drilling results confirm strong brine flow rates and favourable chemistry, supporting confidence in long‑term operational performance.

2. Commercial Partnerships - OEM Alignment

Vulcan has secured several binding and non‑binding agreements with European automotive manufacturers seeking sustainable lithium supply, and these partnerships have become an important pillar of the company’s commercial strategy. They provide clear offtake visibility, ensuring that future production is anchored to committed buyers. They also create strong strategic alignment with evolving EU battery regulations, positioning Vulcan as a compliant, low‑carbon supplier within a tightly regulated market. In addition, these relationships open potential financing pathways linked to decarbonisation mandates, offering avenues for structured funding as the project advances. Taken together, we believe these partnerships materially de‑risk Vulcan’s commercialisation strategy and reinforce the long‑term viability of its Zero Carbon Lithium proposition.

3. Financing and Funding Pathway

Vulcan continues to engage with strategic investors, export credit agencies, and European financial institutions as it advances toward the next phase of development. The company’s integrated energy–lithium model gives it several distinct funding levers. Revenue from renewable geothermal energy provides an early, recurring cash‑flow pathway, while lithium hydroxide offtake agreements create opportunities for structured financing tied directly to long‑term supply commitments. In addition, Vulcan is well positioned to benefit from potential government support under EU critical minerals frameworks, which prioritise domestic, low‑carbon battery material production. Together, these elements form a diversified funding strategy that strengthens the company’s ability to progress Phase One toward full commercialisation.

While capital intensity remains significant, we believe Vulcan’s positioning within Europe’s decarbonisation ecosystem enhances funding optionality.

Financial Strength and Liquidity

Vulcan now presents a materially strengthened financial profile as Phase One advances toward FID, supported by the Lionheart economics that define the core of the Zero Carbon Lithium™ project. The company maintains a solid liquidity position for a pre‑production developer, backed by equity raises, strategic partnerships, and disciplined cost control, while continuing to allocate capital toward drilling, engineering, permitting, and early‑stage construction.

Lionheart’s financial metrics provide clear visibility on long‑term value creation. The project carries a pre‑tax NPV₈ of €1,838 million and post‑tax NPV₈ of €1,152 million, underpinned by a 15.6% pre‑tax IRR and 13.7% post‑tax IRR. Average revenue over the first decade is projected at €566 million per annum, supported by an assumed €20,456/t realised LHM price. Capital intensity is significant, with €1,476 million in CAPEX, but structurally low operating costs -€3,588/t LHM, firmly in the lowest quartile - enable a robust 75% EBITDA margin, a margin profile rarely seen in the lithium sector.

Phase One capacity is expected to deliver 24 kt LHM per year, alongside 275 GWh of power and 560 GWh of heat, creating dual revenue streams that differentiate Vulcan from conventional lithium developers. The project is underpinned by 29.1 Mt LCE, the largest lithium resource in Europe, and supported by 30 years of proven and probable reserves, providing exceptional longevity.

Valuation and Peer Context

Vulcan sits within the high‑growth, high‑optionalities segment of global lithium developers. Its closest peers include:

Standard Lithium (SLI) - DLE‑focused

E3 Lithium -Canadian brine developer

Lithium Americas (LAC) -large‑scale brine and clay projects

European Lithium - EU‑focused hard‑rock developer

Compared with its peer group, Vulcan offers a distinctly differentiated strategic profile. Its integrated geothermal–lithium model is unique, placing the company in direct alignment with EU decarbonisation mandates and giving it a structural advantage as Europe tightens emissions standards for battery materials. Proximity to European gigafactories strengthens its logistical positioning, while a lower enterprise value relative to long‑term revenue potential highlights clear rerating capacity. Added to this is a differentiated ESG profile, underpinned by renewable energy and lowest‑quartile production costs. In our view, the market has yet to fully recognise the strategic value of a domestic, zero‑carbon lithium supplier within Europe.
