Vulcan Energy’s Lionheart Project Gathers Pace, But the Share Price Remains Stuck in the Mud
Published on 07/29/2026 at 12:02 | Redaktion boerse-global.de
The disconnect between Vulcan Energy’s operational milestones and its stock market performance has rarely been starker. While the company is pouring concrete, drilling wells, and locking in major supply contracts, its shares are plumbing depths not seen in a year. The equity closed at €1.61 on Tuesday, barely above the 52-week low of €1.55 hit the previous day — a far cry from the €3.98 peak reached in October 2025.
The culprit isn’t bad news. On the contrary, the second quarter delivered a string of regulatory wins and construction breakthroughs. Investors, however, appear fixated on the pace at which the company is burning through its cash pile as it races toward industrial-scale production.
Siemens signs on for €40 million automation deal
A fresh commercial agreement underscores the project’s maturation. Vulcan has secured a supply contract worth approximately €40 million with Siemens, naming the German industrial giant as its preferred partner for automation and digitalisation technology. The preferential agreement runs through 2035 and represents one of the last major procurement steps for the current construction phase.
The deal adds to a growing list of institutional validations. In the second quarter, the company also finalised a €2.2 billion financing package, with the first equity tranches from funding partners already received after the quarter closed. Total liquidity stood at €273.9 million as of 30 June, comprising €193.9 million in cash and cash equivalents plus €80 million in high-yield term deposits with a 90-day notice period.
Should investors sell immediately? Or is it worth buying Vulcan Energy?
Ground broken at Landau geothermal plant
On the ground, the Lionheart project is advancing according to plan. Civil works have begun at the 30-megawatt geothermal power plant in Landau, following initial earthworks. The roughly ten-hectare site in the Messeplatz SĂĽdost industrial park is now seeing foundations laid, concrete poured for the power plant buildings, and road infrastructure developed.
CEO Cris Moreno described the transition from preparatory earthworks to civil construction as a significant milestone for the geothermal plant — a core component of the integrated lithium and geothermal project. Lionheart aims to produce 24,000 tonnes of lithium hydroxide monohydrate annually, enough for roughly 500,000 electric vehicle batteries, while generating baseload renewable electricity from the same geological source.
The construction phase is slated for completion by 2027. Civil works for the lithium extraction plant in Frankfurt-Höchst are due to start later this year, while drilling for new geothermal wells is already underway. A second drilling site is expected to be operational in the second half of 2026.
Tax break and sixth well complete
Regulatory support has also strengthened. Rhineland-Palatinate has granted Vulcan a five-year exemption from the lithium extraction levy, valid until the end of 2030, designed to de-risk the critical ramp-up phase of Lionheart.
On the drilling front, the sixth production and reinjection well is finished, and the seventh is already in progress. The company has also begun above-ground construction of the central lithium plant in Frankfurt-Höchst.
Board changes and share rights expiry
There have been minor adjustments at the corporate level. In April, HOCHTIEF, a cornerstone investor, appointed Roberto Gallardo to the supervisory board. Meanwhile, 134,225 performance rights lapsed on 28 July after failing to meet vesting conditions. These unlisted securities have no impact on the outstanding share count, though they slightly reduce the potential dilution from incentive instruments. Vulcan now holds 3,028,139 unlisted performance rights.
Vulcan Energy at a turning point? This analysis reveals what investors need to know now.
Technical picture points to oversold conditions
The stock’s slide has been relentless. It now trades 36.95% below its 200-day moving average of €2.53, underscoring the persistent downtrend. Year-to-date losses stand at 36.72%, while the gap from the 52-week high of €3.98 amounts to 59.44%.
Yet the technical indicators suggest the selling may have gone too far. The 14-day relative strength index sits at 29.7, firmly in oversold territory. The annualised 30-day volatility of 36.36% reflects the sharp swings typical of a capital-intensive development-stage company.
Operationally and regulatorially, Vulcan Energy hit nearly all its targets in the second quarter. The market, however, continues to price the stock based on the speed of cash consumption on the road to first production — and that dynamic shows no sign of easing just yet.
