TVL Industry Engagement Update

Alkemy Capital Investments plc (LSE: ALK) is pleased to provide an update on recent industry engagement activities undertaken by its wholly owned subsidiary, Tees Valley Lithium ("TVL"), which continues to see strong engagement across the European battery supply chain, as industry participants increasingly prioritise the development of domestic lithium refining capacity.

Industry Engagement

Representatives of TVL attended the Benchmark GigaEurope Conference in Brussels last week, a leading industry event focused on the global battery supply chain.

TVL entered the conference with an established commercial position, including a binding offtake agreement for up to 40 per cent of planned production capacity with a wholly owned subsidiary of Glencore Plc.

During the conference, TVL held a series of meetings with participants across the battery materials ecosystem, including lithium feedstock suppliers and Tier 1 cathode and battery manufacturers. These discussions focused on potential collaboration across feedstock supply and additional product offtake, as the Company continues to build out its commercial framework.

Following the conference, the Company has commenced follow-up discussions with a number of counterparties across the battery supply chain, including potential feedstock suppliers and Tier 1 offtake participants.

Project Development

Following completion of the Front-End Engineering Design study, TVL has initiated the next phase of project development, focused on advancing commercial, financing and delivery workstreams.

The Company continues to engage with participants across the battery supply chain alongside progressing the development of the Tees Valley Lithium project.

Issue of Shares

The Company also announces that it has agreed to issue 100,000 new ordinary shares (the "New Ordinary Shares") at £3.97 per share, being the closing price on 18 March 2026, to Wave International ("Wave") in connection with engineering and project development services provided to TVL.

Wave has supported the delivery of engineering work for the Tees Valley Lithium project, including contributions to the completed Front End Engineering Design study. The issuance of shares reflects the agreed commercial framework between the parties and provides alignment with the continued development of the Tees Valley Lithium project.

Application will be made for the New Ordinary Shares to be admitted to trading on the Equity Shares (transition) category of the Official List and the Main Market of the London Stock Exchange at 8.00 a.m. on 24 March 2026 ("Admission").

The Company also announces that it has issued 61,004 warrants at an exercise price of £6.15 for a period of 48 months.

TVL CEO Vikki Jeckell commented:

"The level of engagement we are seeing across the European battery supply chain reflects both the progress of the Tees Valley Lithium project and the increasing focus on establishing domestic lithium refining capacity.

Our recent discussions with participants across feedstock supply and Tier 1 customer markets highlight the importance of developing reliable refining infrastructure within Europe, and we continue to advance these engagements as we progress the project through its next phase of development."
