EAU Lithium's former shareholders now hold roughly 108 million shares in Cosmos. EAU Lithium will continue operating as the controlling entity for its Bolivian business, retaining its management team, strategic partnerships, and commercial agreements — including a partnership with Vulcan Energy ResourcesDealroom has a profile for this one.

Two EAU Lithium directors, James Durrant and Todd Romaine, have joined Cosmos's board, with Durrant taking the role of chairman. James Bahen stepped down as non-executive director upon completion of the deal.
Why now? The merger follows Cosmos's March 4, 2026 announcement that it would exercise its option to acquire EAU Lithium and raise capital to fund the transaction. EAU Lithium signed a negotiation agreement in February 2026 with Yacimientos de Litio Bolivianos (YLB), Bolivia's state lithium authority, to deploy Direct Lithium Extraction (DLE) technology in the country.
Bolivia holds some of the world's largest lithium reserves but has struggled to commercialise them. EAU Lithium's focus on DLE technology — specifically Vulcan Energy's Vulsorb process — positions the combined entity to tap that opportunity.
What could go wrong? Operating in Bolivia carries significant political and regulatory risk. The company's progress hinges on its negotiation agreement with YLB advancing to a binding commercial deal, and there is no guarantee that will happen.
DLE technology, while promising, remains largely unproven at commercial scale in South American brine environments. Any technical setbacks could delay development timelines and strain the company's finances.
The signal: Bolivia sits on vast lithium reserves that remain largely untapped, and this merger illustrates how early-growth explorers are increasingly pairing with more mature technology partners — in this case late-growth Vulcan Energy Resources — to de-risk entry into challenging jurisdictions. The structure also hints at a capital strategy: listing on the Frankfurt Stock Exchange positions Cosmos to court European investors already backing Vulcan's Zero Carbon Lithium ambitions, at a time when securing upstream lithium supply is a growing priority for the continent's EV industry.
