Stack BTC Plc (STAK)

WRAP Retail Offer of approximately   £250,000

Stack BTC Plc ("Stack" or the "Company"), the UK-based company focused on building a portfolio of high-quality, cash-generative businesses, alongside a Bitcoin treasury, is pleased to announce the opening of a retail offer via the Winterflood Retail Access Platform ("WRAP Retail Offer") to raise approximately   £250,000   through the issue of approximately 2,500,000 new ordinary shares of £0.01 each in the capital of the Company ("WRAP Retail Offer Shares"), at a price of   10 pence   per share.

Use of Placing, Subscription and WRAP Proceeds

Through a separate announcement earlier today, the Company announced it has raised gross proceeds of   £1,579,400   through the issue of 15,794,000 Ordinary Shares through AlbR Capital Limited (the "Placing") and gross proceeds of £221,300 through the issue of 2,213,000 Ordinary Shares through a Company subscription (the "Subscription"). The net proceeds will be utilised to commence the Company's M&A strategy, buy further Bitcoin to advance the Bitcoin treasury strategy and build a portfolio of high-quality, cash-generative businesses. The proceeds of the WRAP Retail Offer will be utilised in the same way as the proceeds of the Placing and Subscription.

For the avoidance of doubt, the WRAP Retail Offer is not part of the Placing or Subscription. Completion of the WRAP Retail Offer is conditional, inter alia, upon the completion of the Placing and Subscription but completion of the Placing and Subscription is not conditional on the completion of the WRAP Retail Offer.

The WRAP Retail Offer is conditional on the WRAP Retail Offer Shares being admitted to trading on the Aquis Stock Exchange Growth Market ("Admission"). It is anticipated that Admission will become effective and that dealings in the WRAP Retail Offer Shares will commence on the Aquis Stock Exchange Growth Market at 8.00 a.m. on or around 25 March 2026.

Nothing in this announcement amounts to a recommendation to invest in the Company or amounts to investment, taxation or legal advice.

It should be noted that a subscription for Ordinary Shares and investment in the Company carries a number of risks, including the risk that investors may lose their entire investment.   Investors are responsible for assessing whether this investment is suitable for their circumstances and     should take independent advice from a person experienced in advising on investment in securities such as the Ordinary Shares if they are in any doubt.

An investment in the Company will place capital at risk. The value of investments, and any income, can go down as well as up, so investors could get back less than the amount invested.

Notice to distributors solely for the purposes of Paragraph 3.2.7R regarding the responsibilities of UK Manufacturers under the Product Governance requirements contained within 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 Ordinary Shares have been subject to a product approval process by the Company, which has determined that the Ordinary Shares are: (i) compatible with an end target market of (a) retail investors, (b) investors who meet the criteria of professional clients and (c) eligible counterparties, each as defined in UK Product Governance Requirements; and (ii) eligible for distribution through all distribution channels as are permitted by UK Product Governance Requirements (the "Target Market Assessment"). Notwithstanding the Target Market Assessment, distributors should note that: the price of the Ordinary Shares may decline and investors could lose all or part of their investment; the Ordinary Shares offer no guaranteed income and no capital protection; and an investment in the Ordinary 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 fundraise. For the avoidance of doubt, the Target Market Assessment does not constitute: (a) an assessment of suitability or appropriateness for the purposes of MiFID II; 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 Ordinary Shares. Each distributor is responsible for undertaking its own target market assessment in respect of the Ordinary Shares and determining appropriate distribution channels.

Bitcoin Treasury - Important Notice

The Company holds treasury reserves and surplus cash in Bitcoin. Bitcoin is a type of cryptocurrency or cryptoasset. Whilst the Board of Directors of the Company considers holding Bitcoin to be in the best interests of the Company, the Board remains aware that the financial regulator in the UK (the   Financial Conduct Authority   or   FCA) considers investment in Bitcoin to be high risk. At the outset, it is important to note that an investment in the Company is not an investment in Bitcoin, either directly or by proxy and shareholders will have no direct access to the Company's holdings. However, the Board of Directors of the Company consider Bitcoin to be an appropriate store of value and potential growth and therefore appropriate for the Company's reserves. Accordingly, the Company is and intends to continue to be materially exposed to Bitcoin. Such an approach is innovative, and the Board of Directors of the Company wish to be clear and transparent with prospective and actual investors in the Company on the Company's position in this regard.

The Company is neither authorised nor regulated by the FCA, and the purchase of certain cryptocurrencies (such as Bitcoin) are generally unregulated in the UK. As with most other investments, the value of Bitcoin can go down as well as up, and therefore the value of the Company's Bitcoin holdings can fluctuate. The Company may not be able to realise its Bitcoin holdings for the same as it paid to acquire them or even for the value the Company currently ascribes to its Bitcoin positions due to market movements. Neither the Company nor investors in the Company's shares are protected by the UK's Financial Ombudsman Service or the Financial Services Compensation Scheme.

Nevertheless, the Board of Directors of the Company has taken the decision to invest in Bitcoin, and in doing so is mindful of the special risks Bitcoin presents to the Company's financial position. These risks include (but are not limited to): (i) the value of Bitcoin can be highly volatile, with value dropping as quickly as it can rise. Investors in Bitcoin must be prepared to lose all money invested in Bitcoin; (ii) the Bitcoin market is largely unregulated. There is a risk of losing money due to risks such as cyber-attacks, financial crime and counterparty failure; (iii) the Company may not be able to sell its Bitcoin at will. The ability to sell Bitcoin depends on various factors, including the supply and demand in the market at the relevant time. Operational failings such as technology outages, cyber-attacks and comingling of funds could cause unwanted delay; and (iv) cryptoassets are characterised in some quarters by high degrees of fraud, money laundering and financial crime. In addition, there is a perception in some quarters that cyber-attacks are prominent which can lead to theft of holdings or ransom demands. Prospective investors in the Company are encouraged to do your own research before investing.
