Vulcan Energy: VULSORB Goes Commercial as Lithium Sentiment and Custody Filings Set the Tone
Published on 10/25/2026 at 14:01 | Editorial boerse-global.de
Vulcan Energy has begun producing its own lithium-extraction adsorbent, VULSORB, at commercial scale in Germany. The first production campaign is earmarked to supply the extraction columns at the company's Lionheart project, which is scheduled to come online in the second half of 2028. The milestone is a preparatory one: the commercial scale applies to the adsorbent itself, while Lionheart's commissioning still lies ahead.
The operational update landed against a difficult backdrop for lithium equities. Vulcan Energy shares fell 5.6% on Friday to close at €0.6565, caught in a broad selloff of Australian lithium stocks. According to media reports, planned EU restrictions on Chinese hybrid imports deepened worries about lithium demand, while lithium carbonate prices in China slipped again amid downbeat market sentiment. Weaker-than-expected third-quarter results from CATL were cited as an additional drag on the mood. The reports named no company-specific trigger for Vulcan's decline and attributed the move to sector-wide selling pressure; PLS Group and other lithium names also retreated. Lithium prices had already fallen sharply from their May peak.
Custody stakes that are not quite what they seem
Citigroup reported an increased voting stake in Vulcan Energy in a mandatory disclosure on Friday, putting its holding at 11.3823%, up from 9.6615%. The interests described in the filing include securities lending and ordinary market transactions, so the change cannot simply be read as a direct share purchase. JPMorgan Chase & Co.'s previously reported stake likewise includes interests from securities lending and proprietary trading; per the mandatory disclosure published Friday, the substantial holding has existed since Tuesday and amounts to 5.38% of voting rights.
Should investors sell immediately? Or is it worth buying Vulcan Energy?
A well test that clears its own bar
Roughly two weeks ago, Vulcan Energy reported a successful reinjection test at its LSC-3a well — the seventh of 28 wells planned under the development programme. Under the intended operating conditions, the company derived an injection capacity of about 64 standard litres per second, against roughly 40 standard litres per second assumed in the Lionheart field development plan. Vulcan said the result confirms matrix injection as part of the underlying development concept; the higher figure remains explicitly an estimate tied to the planned operating conditions.
Investors get their next formal update on 29 October, when Vulcan Energy is due to publish its third-quarter 2026 results.
