Tees Valley Lithium: Publication of Impact Report

Alkemy Capital Investments plc (LSE: ALK) is pleased to announce that its wholly owned subsidiary, Tees Valley Lithium ("TVL"), has published an Economic, Environmental and Social Impact Report (the "Report") setting out the anticipated contribution of its proposed lithium hydroxide refinery at Billingham, Teesside.

The Report is based on previously disclosed project parameters, including TVL's planned capital investment of approximately US$243 million (£185 million) and is being released following the completion of the preliminary independent Life Cycle Assessment.

TVL's refinery is projected to generate £2.1 billion in Gross Value Added over 25 years, representing more than £11 of economic value for every £1 of capital invested, with a substantial share retained in the Tees Valley and the wider North East.

Highlights of the Report include:

The Report reflects the findings of TVL's Front-End Engineering Design ("FEED") study, previously announced on 3 February 2026, and incorporates the Company's site location in Billingham, including the surrounding port, utilities, and chemical cluster infrastructure, which are identified as key enablers for the project.

The Report highlights the alignment between TVL's Billingham facility and a number of UK Government policy priorities, including the UK Critical Minerals Strategy's objective of building domestic processing capacity for battery materials, the Zero Emission Vehicle mandate's requirement for 100% of new car sales to be zero-emission by 2035, and the Government's wider industrial strategy and levelling-up agenda for the North East and Tees Valley.

The projections set out in the Report are illustrative of the Company's current development plans for Train 1, are not a profit forecast, and remain subject to, inter alia, the completion of financing arrangements and a positive final investment decision.

TVL CEO Vikki Jeckell commented:

"With our FEED study and initial Life Cycle Assessment now complete, this Report gives the clearest picture yet of what TVL's Billingham facility means in practice: over £11 of economic value for every £1 invested, close to 1,700 jobs across construction, operations and supply chain, and a facility designed from day one to be among the lowest-carbon lithium hydroxide producers anywhere in the world. We believe TVL represents a genuinely additive opportunity for the Tees Valley, the wider North East, and the UK's critical minerals strategy, and we look forward to continuing our progress."
