Yellow Cake plc

Results of Placing

Yellow Cake plc (AIM: YCA) ("Yellow Cake" or the "Company"), founded and established by Bacchus Capital Advisers ("Bacchus") 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 18,700,000 new Ordinary Shares (the "Placing Shares") have been placed with existing and new institutional investors at a fixed price of £5.50 per share (the "Placing Price") via an accelerated bookbuild (the "Placing").

The Placing was conducted using the Company's existing share authorities. The Placing comprises 18,700,000 new Ordinary Shares, which will raise gross proceeds of approximately £103 million (approximately US$125 million). The Placing Shares being issued represent approximately 9.4% 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 are delighted with the strong response from both existing and new investors, highlighting the growing interest in, and understanding of, both uranium and the Yellow Cake investment case. This has once again resulted in an oversubscribed book. The recent positive momentum in the uranium price is indicative of the themes we have consistently set out, with supply demand fundamentals and a wider acceptance of the critical role nuclear energy will play in supporting our net zero ambitions both acting as long-term drivers. Looking ahead, we remain confident that spot and term prices will need to increase further to reach an incentive price which supports the construction of the new greenfield mines that are needed to meet mid and long-term uranium demand expectations."

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.
