Important Notices

The Company intends to hold treasury reserves and surplus cash in bitcoin. Bitcoin is a type of cryptocurrency or crypto asset. 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. However, the Board of Directors of the Company consider bitcoin to be an appropriate store of value and growth for the Company's reserves and, accordingly, the Company is 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 cryptocurrencies (such as bitcoin) are 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 bitcoin holdings can fluctuate. The Company may not be able to realise any future bitcoin exposure for the same as it paid in the first place or even for the value the Company ascribes to bitcoin positions due to these market movements. As bitcoin is unregulated, the Company is not 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 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) crypto assets 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. The Board of Directors of the Company does not subscribe to such a negative view, especially in relation to bitcoin. However, prospective investors in the Company are encouraged to do their own research before investing.
