Short Sellers Circle Vulcan Energy Even as Lionheart Cash Piles Up
Published on 07/23/2026 at 14:22 | Redaktion boerse-global.de
Lithium developer Vulcan Energy is presenting investors with a puzzle. The company has locked down billions in project financing and boosted its cash reserves to levels not seen in its history, yet short sellers are adding to their bearish bets and the stock has slumped to a two-year low.
Shares closed at €1.64 on Wednesday, just 2.05 percent above the 52-week trough of €1.61 hit earlier in the session. That marks a 58.74 percent collapse from the October 2025 high of €3.98. The stock has shed 17.10 percent over the past month alone, bringing the year-to-date decline to roughly 35 percent — though a small bounce on Thursday lifted the price to €1.68, a 2.31 percent gain.
Short Interest Climbs Despite Funding Milestone
The most recent short report from FNArena, dated July 23, puts the short interest in Vulcan Energy at 6.89 percent, up from 5.88 percent at the end of June. Bearish speculators are increasing their positions even as the company ticks off major financing boxes.
On July 15, Vulcan confirmed it had satisfied the initial conditions for drawing down capital from its multibillion-euro funding package for the Lionheart project — a combined lithium extraction and geothermal energy development in the Upper Rhine Valley. The package reached financial close in late May, and the company says equity contributions from strategic partners have already started flowing.
Should investors sell immediately? Or is it worth buying Vulcan Energy?
The rising short interest against this backdrop raises a natural question: what are the bears worried about? The answer may lie in the company's cash burn.
Cash Pile vs. Cash Burn
A Simply Wall St analysis from July 21 flags a stark reality: at current free cash flow trends, Vulcan has less than a year of liquidity runway. Free cash flow was negative €98 million in the latest period. The company also has a history of significant share dilution that has weighed on the stock in the past.
Yet the balance sheet tells a more nuanced story. Cash and equivalents have surged from €97.1 million to roughly €517.8 million in 2025, against total debt of about €40.8 million. With a market capitalisation of €791.14 million, a substantial chunk of the company's valuation is backed by hard cash. The €2.2 billion Lionheart financing package for the first construction phase provides additional financial headroom.
The catch: Vulcan remains firmly in the pre-revenue phase on the lithium side. Revenue stands at just A$12.94 million, while the company booked a net loss of roughly €69.6 million for fiscal 2025. The cash pile acts as a buffer, but the investment thesis still hinges entirely on successful project execution.
Institutional Caution and Technical Weakness
Institutional investors are also showing signs of caution. State Street Corporation disclosed on July 17 that its stake in Vulcan had fallen to 2.97 percent as of July 10, down from 3.01 percent and slipping below the reporting threshold.
The technical picture reinforces the bearish positioning. The 14-day relative strength index sits at 36.5 — one source puts it at 32, approaching oversold territory. Either reading points to negative momentum. The stock trades well below both its 50-day moving average of €2.01 and its 200-day average of €2.56, confirming that the downtrend has legs beyond the short term.

What Comes Next
No single corporate event triggered the latest leg lower. There was no profit warning, no surprise announcement — just a market that appears to be pricing in fundamental doubts about construction timelines and the path to commercial lithium production.
The next major test arrives on July 30, when Vulcan releases its second-quarter report. Investors will scrutinise construction progress, capital expenditure, and the pace of Lionheart drawdowns. A separate financial update is scheduled for September 11, which will provide further detail on cash consumption and build-out milestones.
Until concrete production targets are met, analysts expect the stock to remain volatile in the €1.60 to €2.00 range. The July quarterly report will be the first real test of whether the funding progress can outweigh the balance sheet concerns — or whether the short sellers have read the situation correctly.
