Since April 2010, companies looking to list in the UK have had a wider choice for listing their shares on the main market for listed securities (the “Main Market”) of the London Stock Exchange plc (the “LSE”). The Main Market is the LSE’s principal market for listed companies from the UK and overseas. There is a choice between a “premium” and a “standard” listing on the UKLA’s Official List. Alternately, there is the option to list on the Alternative Investment Market (“AIM”), on which many smaller and growth companies are traded. 
On 27 March 2013, the LSE launched the new High Growth Segment (the “HGS”) of its Main Market and published the final version of the HGS Rulebook.  The HGS has been designed for high growth issuers that are seeking a listing on the Main Market due to their size and stage of development. There are some parallels with the US’s relaxation of certain regulatory requirements under the Jumpstart Our Business Startups (JOBS) Act to encourage “emerging growth companies” to list in the US. The HGS is intended to provide issuers with a transitional route to the UKLA’s Official List and, as such, should help issuers prepare for admission to the UK’s listed premium market over time and the obligations that accompany it. Indeed, HGS issuers must “clearly set out their intention” to eventually join the Main Market (if and when they become eligible).
