CleanTech Lithium PLC ("CleanTech" or "CTL" or the "Company") 

Results of WRAP Retail Offer

Investor Webinar

CleanTech Lithium PLC (AIM: CTL), an exploration and development company advancing sustainable lithium projects in Chile, is pleased to announce the results of its retail offer via the Winterflood Retail Access Platform (the "WRAP Retail Offer").

The WRAP Retail Offer was well supported and has conditionally raised gross proceeds of £603,830 in addition to the £4.77 million (gross) Placing proceeds announced on 5 June 2026.  The net proceeds from the WRAP Retail Offer will be applied in the same way as the net Placing proceeds. The WRAP Retail Offer, the Conditional Placing, the Subscription and the grant of the Warrants and the Bookrunner Warrants (each defined in the Launch Announcement on 4 June 2026) are conditional on shareholder approval at a General Meeting scheduled for 1 July 2026.

Ignacio Mehech, CEO, CleanTech Lithium Plc, commented:

"I would like to extend my thanks to retail investors who, alongside institutional investors, have supported CleanTech Lithium as we progress our flagship project Laguna Verde in Chile. This fundraising and the associated conversion of loan notes, in my view, reflect encouraging confidence in our long-term plan to develop lithium projects of high quality."

Results of the WRAP Retail Offer

10,063,749 new ordinary shares ("Retail Offer Shares") will be issued to new retail investors or existing retail shareholders who subscribed via the Winterflood Retail Access Platform ("WRAP") at a price of 6 pence per Retail Offer Share (the "Issue Price").  In addition, the Retail Offer Shares carry a warrant entitlement of one warrant ("Warrant") for every two Retail Offer Shares issued. Each Warrant grants the holder the right to subscribe for one new ordinary share at a price of 9 pence, being at a 50% per cent premium to the Issue Price, at any time from one year after the date of Second Admission until up to and including the date which is 3 years from the date of Second Admission expected to take place on or about 2 July 2026.

Subject to shareholder approval, a total of 10,063,749 Retail Offer Shares and 5,031,874 Warrants will be issued pursuant to the WRAP Retail Offer, and noting that fractional entitlements to Warrants will not be issued but rather rounded down to the nearest whole number. 

The Retail Offer Shares will, when issued, be credited as fully paid and will rank pari passu in all respects with the existing ordinary shares of the Company, including the right to receive all dividends or other distributions made, paid or declared in respect of such shares after the date of issue of the Retail Offer Shares.
