Vulcan Energy Bolsters Board and Insider Buying Emerges as Lionheart Construction Gathers Pace

Vulcan Energy advances Lionheart plant construction, gains new director and insider buying, while Citigroup and BNP adjust stakes amid volatile stock.

The recent flurry of activity around Vulcan Energy tells two distinct stories. On one hand, the company is laying groundwork for its most critical operational phase yet — the construction of the Lionheart geothermal power plant. On the other, the share register is churning with institutional repositioning, while management signals its own conviction through a fresh insider purchase and a new board appointment.

Boardroom Reinforcements

Amanda Lacaze joined Vulcan Energy as an independent non-executive director on 17 August, taking a seat on the audit, risk and ESG committee. The company disclosed the appointment on 3 August, and the announcement also revealed Lacaze holds 39,350 fully paid ordinary shares. Her arrival extends a series of governance enhancements the company has made in recent weeks, positioning the board for the operational milestones ahead.

The timing is no coincidence. With Lionheart entering its decisive construction phase, the company is clearly seeking experienced oversight. Lacaze's appointment adds weight to a leadership team preparing for the multi-year build-out that will ultimately determine Vulcan's valuation.

Insider Confidence Amid Institutional Flux

Just days before Lacaze's appointment was announced, the market received another signal. Cristobal Moreno, a member of management, purchased company shares on 13 August, a transaction disclosed under directors' dealings rules. Insider buying is frequently interpreted by investors as a sign that management considers the equity undervalued — a particularly meaningful gesture when the stock trades well below its longer-term averages.

The share register tells a more complicated story. Citigroup Global Markets Australia and affiliated entities lifted their combined voting rights to 4.19 percent, a change effective 20 August and disclosed on 26 August under German securities law. This follows a series of Citigroup-related notifications that have repeatedly drawn investor attention over recent weeks.

Meanwhile, BNP Paribas Funds moved in the opposite direction, trimming its stake to 3.00 percent from 3.37 percent roughly two weeks ago. The threshold was crossed on 14 August, with the remaining position comprising 14,347,011 voting rights attached to shares. Since that reduction, the stock has given back 8.1 percent.

A Stock Caught Between Recovery and Resistance

The share price reflects this mixed backdrop. Vulcan closed Friday at EUR 1.67, up 2.6 percent on the day, yet still down 1.8 percent on the week. The 30-day picture shows a 5.5 percent recovery, but the year-to-date decline stands at a painful 35 percent — a far cry from the 52-week high of EUR 4.15 reached in October 2025.

Technical indicators underscore the fragility. The stock remains below its 50-day moving average of EUR 1.76 and significantly under the 200-day average of EUR 2.23, suggesting the broader downtrend has yet to break despite the recent bounce. At 11 percent above the late-July 52-week low of EUR 1.50, there are tentative signs of a base forming, though the 48 percent 30-day volatility offers little comfort to skittish holders.

Interestingly, the stock has gained 7.3 percent since construction at Lionheart commenced roughly a month ago, and an early-August disclosure that Citigroup-affiliated entities held over five percent reportedly pushed the shares up 3 percent at the time.

Lionheart: The Fundamental Anchor

For all the short-term noise, Lionheart remains the central value driver. A company presentation dated 24 August showed progress on earthworks, high-voltage line installation and the first concrete foundations at the Landau geothermal power plant site. Preliminary work has also begun at the planned lithium chemicals facility in Frankfurt.

The timeline laid out in the presentation targets completion of certain site works in the third quarter of 2026, with first upstream production and first lithium chemicals production slated for 2028. Commercial ramp-up is projected for 2029.

That multi-year horizon stands in stark contrast to the day-to-day trading dynamics — the shifting institutional positions, the volatile swings, the technical resistance levels. For investors, the question is whether the boardroom reinforcement, insider buying and construction progress can eventually outweigh the market's persistent skepticism. The answer will largely depend on how smoothly Lionheart advances and where lithium prices head in the interim.
