Short Sellers Intensify Pressure on Vulcan Energy Despite €2.2 Billion Lionheart Financing Milestone
Published on 06/15/2026 at 10:06 | Redaktion boerse-global.de
Vulcan Energy has crossed a pivotal financing threshold for its Lionheart project in Germany’s Upper Rhine Valley, yet the market’s mood remains distinctly sour. A consortium of 13 lenders, including the European Investment Bank, several export credit agencies and commercial banks, has closed a €2.2 billion funding package for the first phase of development. The money can now be drawn down as needed.
But rather than rewarding the milestone, bears have been doubling down. New data from Australia shows the short interest in Vulcan Energy has climbed to 5.16% of shares outstanding — a marked increase from the prior week. The reading reflects positioning through early June and therefore lags current trading, but it signals growing conviction among hedge funds that the stock will fall further.
Price bounces, but stays below key averages
The equity itself has shown some resilience in recent sessions. On Monday it rallied 4.65% to €2.12, bringing it within a whisker of the 50-day moving average at €2.14. That technical level now acts as a short-term resistance point. Should the shares push through, short sellers may begin to cover, adding upward momentum. A failure to hold could see the bears emboldened to test the year’s lows.
Despite the bounce, the stock is still trading roughly 19% lower year-to-date and sits about 22% below its 200-day moving average of €2.61. The 52-week high of €3.98 is nearly 50% above Friday’s close of €2.02. The relative strength index stands at 41.6 — under downward pressure but not yet oversold — while annualised volatility above 56% underscores the nervousness surrounding a project with such enormous capital requirements.
Should investors sell immediately? Or is it worth buying Vulcan Energy?
Drilling and construction advance in parallel
On the operational front, work is accelerating. The sixth well at the LSC-2 site has reached its target depth of 3,000 metres, and completion work together with flow tests are next, aimed at confirming the productivity of the brine. Meanwhile, the central lithium chemical plant is taking shape at the Industriepark Höchst in Frankfurt. There, electrolysis will convert lithium chloride extracted from the geothermal brine into battery-grade lithium hydroxide.
Vulcan markets the integrated model as “Zero Carbon Lithium” because the geothermal energy itself provides both heat and electricity as by-products. At full capacity, Phase One is designed to produce 24,000 tonnes of lithium hydroxide annually — enough to supply roughly 500,000 electric vehicles.
Lithium price stabilisation offers some comfort
The spot lithium price has steadied near $29,000 per tonne, providing a more predictable backdrop for the project’s economics than the volatile swings seen last year. That, along with the secured financing and active construction, might seem to justify a higher valuation. Yet the market is clearly demanding proof of execution before it re-rates the stock.
Vulcan Energy at a turning point? This analysis reveals what investors need to know now.
Commercial production from Phase One is still ahead, and until tangible output data emerges from the Upper Rhine Valley, investors appear inclined to stay cautious. The high short interest adds a layer of uncertainty: if the recovery can break through €2.14, covering could accelerate; if the lithium market weakens again, the elevated bearish positioning gives short sellers plenty of ammunition to push the stock back toward its year-to-date troughs.
