Results of Placing

Yellow Cake plc (AIM: YCA), founded and established by Bacchus Capital Advisers to be a specialist company operating in the uranium sector with a view to holding physical uranium for the long-term, is pleased to announce that 15,000,000 new Ordinary Shares (the "Placing Shares") have been placed with existing and new institutional investors at a fixed price of £4.12 per share (the "Placing Price") via an accelerated bookbuild (the "Placing").

Due to strong investor demand, the Company agreed with the Joint Bookrunners to increase the size of the Placing to approximately US$75 million from the approximately US$50 million originally proposed.

The Placing was conducted utilising the Company's existing share authorities.

The Placing comprises 15,000,000 new Ordinary Shares, which will raise gross proceeds of approximately £61.8 million (approximately US$75 million). The Placing Shares being issued represents approximately 8.19% of the existing issued ordinary share capital (excluding treasury shares) of the Company prior to the Placing.

Andre Liebenberg, Chief Executive Office of Yellow Cake, commented:

"We have been delighted with the response to our placing and would like to thank shareholders for their continued support. Demand was again considerable, supporting our view that this remains a compelling time to invest in uranium. Supply demand fundamentals, the increasing global acceptance of nuclear to support future energy security and the new theme of term market strength, all give us confidence in the long term momentum in the uranium price."

It is expected that Admission will become effective at commencement of trading on 7 February 2023 and settlement is expected to take place on the same date on a T+2 basis.

Solely for the purposes of the product governance requirements of Chapter 3 of the FCA Handbook Product Intervention and Product Governance Sourcebook (the "UK Product Governance Requirements"), and disclaiming all and any liability, whether arising in tort, contract or otherwise, which any "manufacturer" (for the purposes of the UK Product Governance Requirements) may otherwise have with respect thereto, the Shares have been subject to a product approval process, which has determined that the Placing Shares are: (i) compatible with an end target market of retail investors and investors who meet the criteria of professional clients and eligible counterparties, each defined in paragraph 3 of the FCA Handbook Conduct of Business Sourcebook; and (ii) eligible for distribution through all permitted distribution channels to professional clients and eligible counterparties (the "Target Market Assessment").

Notwithstanding the Target Market Assessment for the Placing Shares, distributors should note that: the price of the Placing Shares may decline and investors could lose all or part of their investment; the Placing Shares offer no guaranteed income and no capital protection; and an investment in the Placing 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 offering of the Placing Shares. Furthermore, it is noted that, notwithstanding the Target Market Assessment, the Joint Bookrunners will only procure investors who meet the criteria of professional clients and eligible counterparties.

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

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