Vulcan Energy’s Lionheart Clears Final Financial Hurdle, Shifts Focus to Construction Milestones

The €2.2 billion financing package for Vulcan Energy’s Lionheart project has formally closed, marking the transition from planning to execution for one of Europe’s most ambitious lithium-geothermal ventures. The company achieved financial close on 28 May, removing what had been the single largest risk hanging over the stock in recent months.

A consortium of 13 institutions has committed roughly €1.2 billion in senior loans, supplemented by more than €204 million in government grants. The lenders include the European Investment Bank, five export credit agencies such as Bpifrance and Export Finance Australia, and seven commercial banks including BNP Paribas, ING and UniCredit. Vulcan structured the capital at project, subsidiary and corporate levels, with future drawdowns tied to construction progress and the investment plan.

Lionheart is designed to produce 24,000 tonnes of lithium hydroxide monohydrate annually — enough to equip around 500,000 electric vehicles. Over a 30-year operating life, the project is also expected to generate 275 GWh of renewable electricity and 560 GWh of thermal energy as by-products. Around 72% of planned output is already covered by fixed-price or floor-price offtake agreements, including a 128,000-tonne, ten-year deal with Stellantis, a 31,000-tonne contract with LG Energy Solution, and commitments from Umicore and Glencore.

On the construction front, the sixth well at Lionheart, LSC-2, has reached its target depth of 3,000 metres, with completion work and flow tests due in the current quarter. Drilling of LSC-3 and LSC-4 is scheduled for later this year and into 2026. Production well LSC-1 is already delivering flow rates between 105 and 125 litres per second, and a second drilling rig is expected to be mobilised in the second half of 2026. Vulcan is also installing a commercial electrolysis system at the Industriepark Höchst in Frankfurt, having named Siemens as preferred supplier for automation and digitalisation technology under an agreement running to 2035.

Should investors sell immediately? Or is it worth buying Vulcan Energy?

The stock responded briskly to the financing news: on the ASX, shares jumped roughly 8%, while the Frankfurt listing closed on Friday at €2.39, a one-day gain of 6.5%. Over seven days the equity has advanced about 10%. Yet the longer-term picture remains subdued. The 52-week high of €3.98, set in October 2025, still lies 40% above the current level, and the stock is down around 8.5% year to date. The relative strength index of 4.4 points to extreme oversold conditions — a technical reading that historically precedes sharp reversals, and the recent bounce appears to fit that pattern.

What happens next will hinge on execution milestones. The LSC-2 flow test results are expected in the second quarter, followed by the half-year report on 11 September. A quarterly update for the June period lands on 30 July. Macro factors could also lend a hand: Eurostat publishes its May inflation estimate on 2 June, and the European Central Bank holds its next policy meeting on 10-11 June. Lower borrowing costs would improve the economics of long-duration infrastructure projects like Lionheart.

Ownership dynamics are shifting as well. VanEck Associates has raised its stake to 6.06%, equating to roughly 28.96 million shares. Hochtief’s strategy chief, Roberto Gallardo, is joining the supervisory board, adding another experienced voice to the governance side. Hochtief invested €169 million in Vulcan last December and now holds 15.4% of the company.
