The Company is also conducting a placing of new Ordinary Shares (the "Placing Shares") at the Issue Price by way of a Company led direct placing (the "Placing") as announced earlier today. Through the PrimaryBid Offer, the Company is providing its existing retail shareholders and other investors with the opportunity to participate on the same terms as the Placing. In keeping with the principle of soft pre-emption, the Company will give allocation preference to existing shareholders.

As part of the Placing, Clean Power Hydrogen PLC, the UK manufacturer of electrolysers together with certain directors and senior employees in the Company have subscribed for a total of 2,235,634 Placing Shares.

The PrimaryBid Offer is conditional on the Placing Shares and the Retail Shares being admitted to trading on AIM ("Admission"). Admission is expected to be take place at 8.00 a.m. on 20 December 2022. The PrimaryBid Offer will not be completed without the Placing also being completed.

The Company will use the funds to provide itself with further funding to expedite its growth including the Villeta Project, in addition to allowing it to further exploit other opportunities as well as general working capital purposes.

Details of the PrimaryBid Offer

Notice to distributors

Solely for the purposes of the product governance requirements contained within: (a) the UK's implementation of EU Directive 2014/65/EU on markets in financial instruments, as amended ("UK MiFID II"); and (b) the UK's implementation of Articles 9 and 10 of Commission Delegated Directive (EU) 2017/593 supplementing UK MiFID II, and in particular Chapter 3 of the Product Intervention and Product Governance Sourcebook of the FCA (together, the "MiFID II Product Governance Requirements"), and disclaiming all and any liability, whether arising in tort, contract or otherwise, which any "manufacturer" (for the purposes of the MiFID II Product Governance Requirements) may otherwise have with respect thereto, the Retail Shares have been subject to a product approval process, which has determined that the Retail Shares are: (a) compatible with an end target market of (i) retail investors; (ii) and investors who meet the criteria of professional clients and eligible counterparties and (b) eligible for distribution through all distribution channels as are permitted by UK MiFID II (the "Target Market Assessment"). Notwithstanding the Target Market Assessment, distributors (such term to have the same meaning as in the MiFID II Product Governance Requirements) should note that: (a) the price of the Retail Shares may decline and investors could lose all or part of their investment; (b) the Retail Shares offer no guaranteed income and no capital protection; and (c) an investment in the Retail  Shares is compatible only with investors who do not need a guaranteed income or capital protection, who (either alone or in conjunction with an appropriate financial or other adviser) are capable of evaluating the merits and risks of such an investment and who have sufficient resources to be able to bear any losses that may result therefrom. The Target Market Assessment is without prejudice to the requirements of any contractual, legal or regulatory selling restrictions in relation to the PrimaryBid Offer. 

For the avoidance of doubt, the Target Market Assessment does not constitute: (a) an assessment of suitability or appropriateness for the purposes of UK MiFID II; or (b) a recommendation to any investor or Company of investors to invest in, or purchase, or take any other action whatsoever with respect to, the Retail Shares. 

Each distributor is responsible for undertaking its own target market assessment in respect of the Retail Shares and determining appropriate distribution channels.
