High Growth Segment or HGS meaning

In UK capital markets practice, the High Growth Segment (HGS) is the London Stock Exchange’s Main Market segment used to admit fast‑growing, revenue‑generating companies, often as a stepping‑stone to a later premium listing. It is a UK regulated market but sits outside the FCA’s Official List. Admission and continuing obligations are set by the LSE’s High Growth Segment Rulebook, which forms part of the LSE Admission and Disclosure Standards. The term is not defined in legislation or case law; it is a rulebook term used in LSE documentation and market practice. Because HGS securities trade on a UK regulated market, the UK Prospectus Regulation regime, the FCA’s Disclosure Guidance and Transparency Rules (DTRs) and the UK Market Abuse Regulation (UK MAR) apply, in addition to the HGS rule requirements. Eligibility is targeted at companies incorporated in the UK or an EEA state with demonstrable revenue generation and growth, appropriate financial reporting and governance. The segment is designed to provide regulated‑market access with obligations tailored to growth issuers, while facilitating potential transition to a premium listing. Usage and legal effect are consistent across England & Wales, Scotland and Northern Ireland. In Ireland, the term refers to this LSE segment, not a category on Euronext Dublin.
