LSEG works closely with the FCA and key advisers on deals to provide an efficient listing process that best suits the needs of issuers.
  • International Securities Market (ISM) is LSEG’s Exchange Regulated Market and operates as a Multilateral Trading Facility (MTF) under UK law. ISM operates under its own Rulebook, which provides for tailored Admission and Disclosure requirements.
