Vulcan Energy's Lionheart Build-Out Presses Ahead as Ownership Register Reshuffles

Vulcan Energy closed at EUR 1.09, up 4.1%, yet remains 57% lower this year as Lionheart commissioning is slated for H2 2028.

Vulcan Energy shares closed Friday's session at EUR 1.09, a gain of 4.1 percent, without any fresh company-specific announcement to explain the move. The advance offers little comfort against the broader picture: the stock has shed 57 percent since the start of the year, and Friday's close leaves it just 4.6 percent above its 52-week low.

At the heart of the company's long-term strategy sits Project Lionheart, the geothermal brine lithium extraction venture whose commissioning is slated for the second half of 2028. Roughly two weeks ago, Vulcan began commercial output of VULSORB, its proprietary adsorbent, in Germany. The first volumes are destined to serve as the initial fill for the project's extraction columns.

Company figures put the material's performance in earlier trials at an extraction efficiency of as much as 95 percent across thousands of operating cycles. The market, however, has not rewarded that technical progress. Since VULSORB production started roughly two weeks ago, the shares have fallen 20.2 percent — a reminder of the long stretch between engineering milestones and actual revenue, and of a sector where prices swing widely before any commercial output begins.

Investors face a waiting game that extends well beyond the current news flow. Delays or cost overruns on the road to startup remain the key uncertainties, and the industrial build-out demands substantial upfront spending and ties up considerable resources before the first income arrives.

Diverging moves among major holders

Alongside the operational groundwork, Vulcan's shareholder base has been shifting. Regulatory disclosures revealed changed voting rights at significant investors, illustrating how differently institutional and strategic players are positioning themselves at this stage.

The Goldman Sachs Group expanded its holding, with its total stake rising to 5.20 percent from 5.02 percent, crossing the threshold on September 17. The bulk of that position is held through financial instruments, while the share of voting rights attached to directly held stock is small.

Francis Wedin moved in the opposite direction. His stake in Vulcan Energy fell to 1.98 percent, down from a previous 4 percent, with that threshold crossing dated September 24. The two filings point to reallocation rather than any change in the operational direction of the projects.

What emerges is a company pulled by two distinct forces: technical steps on Lionheart that are being pushed forward incrementally, and a shareholder register in flux that keeps sending mixed signals. With commissioning still years away, how faithfully the interim milestones are delivered will shape how the market reads Vulcan Energy from here.
