The Main Market’s High Growth Segment

Your Vision. Your Business. Your Public Market.

  • A dedicated segment that acts as a launch pad for growth businesses to increase their visibility with the analyst and investor community, as well as enhance their business profile with existing and potential customers and suppliers.
  • The segment’s free float requirement at admission enables founder shareholders, including venture and private equity investors, to float a smaller percentage of the company at an earlier stage of development, as the company transitions from privately-owned to the public markets.
  • Companies enjoy significant benefits from being on a London market – in particular access to capital on an ongoing basis from a diverse and deep investor pool; ability to use shares as acquisition currency; access to an expert advisory community to help gain profile; and a regulatory framework that provides investor confidence without proving burdensome.

  • Publish an prospectus approved by the Financial Conduct Authority (FCA) or another EEA competent authority.
