12th November, 2026 – Altilium, a UK-based clean technology company focused on sustainable recovery of critical battery materials, has today announced an employee secondary share sale through Crowdcube, Europe’s leading private market investment platform.

The offer will allow eligible Altilium employees to sell a proportion of their shares through the Crowdcube platform, providing an opportunity for long-serving staff to unlock some of the financial value they have helped create as the company has grown.

Crowdcube will exclusively manage the employee selling and investor purchasing process, facilitating the transfer of existing shares to participating investors. The transaction is designed to provide liquidity for employees without requiring them to wait for a future company sale or public listing.

The announcement comes as Altilium accelerates the commercialisation of its patented EcoCathode™ technology and scales up its UK operations to establish a domestic supply of critical battery materials recovered from end-of-life EV batteries and manufacturing scrap.

The company already operates the UK’s only pilot plant for recovery of cathode and anode materials from black mass at its ACT 2 facility in Plymouth. Construction has also begun on its ACT3 commercial facility, supported by an £18.5 million award through the UK Government’s DRIVE35 programme.

The expansion comes as a new report from the House of Commons Business, Innovation, Science and Trade Committee warns of the UK’s reliance on overseas supply chains for critical minerals essential to EVs, advanced technologies and defence. Altilium is helping address this strategic challenge by establishing a fully circular UK battery materials supply chain, reducing reliance on imported materials and strengthening industrial resilience.

The announcement also follows recent investment from strategic shareholders SQM, one of the world’s leading lithium producers, and Japanese trading and investment group Marubeni Corporation, as part of Altilium’s Series B2 funding round. Both companies were early investors in Altilium, with SQM leading the $12 million Series A round and Marubeni joining as a key investor in the subsequent Series B.

Christian Marston, Altilium COO, commented: “Our people have been instrumental in taking Altilium from an ambitious technology start-up to a business developing the infrastructure needed to build a new strategic industry for the UK. As we move towards commercial-scale operations, we want our employees to share in the success of the business and demonstrate that building innovative clean technology companies in the UK can create real financial value for the people behind them.”

Matt Cooper, Crowdcube’s CEO, said: “Altilium has built a British champion – proprietary technology helping the UK become more self-sufficient in the critical minerals needed for the tools of tomorrow. With our experience in providing liquidity at all stages of a private company’s growth journey, we’re delighted to help Altilium’s employees realise some of the value they’ve created.”

Altilium’s UK team has grown from 13 to 46 employees in the space of just six years, with staff working across its three sites in Tavistock and Plymouth to build the UK’s first closed-loop supply chain for EV battery materials.

By establishing a secure, sustainable domestic supply of critical minerals, including lithium, nickel, cobalt and graphite, the company is helping reduce the UK’s reliance on imported battery materials and minimise the environmental impact of primary mining.

The planned secondary share sale represents a further milestone in Altilium’s corporate development as it progresses towards commercial-scale operations and continues to expand its UK workforce. The move strengthens Altilium’s ability to attract and keep skilled engineers, scientists and operators in a competitive regional market, where new industries are growing fast.

About Altilium

Altilium is building the UK’s first sustainable critical materials platform, creating a sovereign domestic source of battery materials for Britain’s automotive, energy and advanced manufacturing sectors.

Combining first-of-a-kind industrial-scale infrastructure, patented materials processing technology and AI-powered digital intelligence, the company recovers, refines and returns critical minerals to UK industry – delivering domestically sourced and sustainable battery materials that reduce reliance on imports, strengthen national resilience and dramatically lower carbon emissions.

The company’s proprietary EcoCathode™ and EcoAnode™ processes convert end-of-life EV batteries and manufacturing scrap into domestic, sustainable, battery precursors, cathode active materials (CAM), cathode precursor (pCAM) and anode active material (AAM), for direct reuse in new batteries.

Altilium’s ACT 2 pilot plant commenced operations in Plymouth in 2025 while its ACT 3 commercial-scale facility is currently under construction. Its planned ACT 4 plant will be one of the largest EV battery recycling facilities in Europe, with capacity to process scrap from over 150,000 EVs per year, producing 30,000 MT of CAM, enough to meet over 20% of the UK’s expected needs by 2030.

The company is backed by Sociedad Quimica y Minera de Chile (SQM), Japanese trading and investment group Marubeni Corporation and Mizuho Bank.
