Specifically tailored for the needs of smaller, growth companies, AIM combines the benefits of a public quotation with a flexible regulatory approach. AIM gives smaller and growing companies of all sectors access to a public market at an earlier stage of their development, whilst providing a central focus for investors who understand growing companies and are keen to invest in their potential.

Whether as a means of gaining your first experience of a public market, or as a stepping stone to the Main Market, the flexibility of AIM makes it attractive to a wide range of companies, from young, venture-backed businesses or long established family concerns to growing companies requiring capital for development and acquisition. AIM gives companies from all countries and sectors access to the market at an earlier stage of their development, allowing them to experience life as a public company.

An AIM quotation offers:

  • A flexible regulatory regime
  • Access to a unique, globally respected market
  • Access to a wide pool of capital
  • Enhanced profile & heightened interest in your company
  • Increased status and credibility
  • Currency for and easier rules on acquisition
  • Eligibility for a range of tax benefits
