The Main Market is also one of the world's most international and diverse stock markets and there are different routes to joining which are outlined below:

Routes to Main Market



The   Premium segment is only open to equity shares issued by trading companies and   investment entities. Issuers with a Premium Listing are required to meet the   UK’s super-equivalent rules which are higher than the EU minimum   requirements. Premium Listed companies comply with the UK’s highest standards   of regulation and corporate governance, as a consequence they may enjoy a   lower cost of capital through greater transparency and through building   investor confidence.


The   Standard segment is open to issuance of equity shares, Global Depositary   Receipts (GDRs), debt securities, and securitised derivatives that are   required to comply with EU minimum requirements. A Standard Listing allows   issuers to access the Main Market by meeting EU harmonised standards.

High   Growth Segment

The new   High Growth Segment is subject to the EU minimum standards and the HGS   rulebook issued by London Stock Exchange. The segment is designed   specifically for high growth, revenue generating businesses incorporated in   an EEA state, that over time are aspiring to the join the Premium segment.

As successful companies expand in today's global market place, they need capital to fund their growth. An admission to London Stock Exchange’s Main Market enables companies to access deep pools of capital and gain benefits of an enhanced profile and liquidity. These benefits are underpinned by the Main Market's balanced and respected framework of regulation and corporate governance.

Companies who are not yet eligible for Premium or Standard Listing on the Main Market can now gain access to capital via our High Growth Segment which provides companies the opportunity to fund their growth whilst preparing for an official listing in the future.

In general, the Main Market suits ambitious companies that are confident that they can exploit the benefits that the market offers, and meet its high standards of disclosure, governance and regulation.
