The Access segment of the AQSE Growth Market, which is operated by Aquis Stock Exchange Limited (“Aquis Stock Exchange“), a recognised investment exchange under Part XVIII of FSMA, is a market designed primarily for emerging or smaller companies to which a higher investment risk tends to be attached than to larger or more established companies. It is not classified as a regulated market under Directive 2014/65/EU of the European Parliament and of the Council on markets in financial instruments, and AQSE Growth Market securities are not admitted to the Official List of the FCA. Investment in an unlisted company is speculative and tends to involve a higher degree of risk than an investment in a listed company. The value of investments can go down as well as up and investors may not get back the full amount originally invested. An investment should therefore only be considered by those persons who are prepared to sustain a loss on their investment. A prospective investor should be aware of the risks of investing in AQSE Growth Market securities and should make the decision to invest only after careful consideration and, if appropriate, consultation with an independent financial adviser authorised under FSMA if you are in the UK or, if not, another appropriately authorised independent financial adviser who specialises in advising on the acquisition of shares and other securities.
