NEX Group plc, formerly known as ICAP plc, is a UK-based business focused on electronic markets and post-trade business. The company was listed on the London Stock Exchange until it was acquired by CME Group in November 2018.
The company developed from a merger between Garban plc and Intercapital plc which created Garban-Intercapital plc in 1999. Intercapital plc was founded by Michael Spencer in 1986 as Intercapital Private Group Limited ('IPGL'); in 1998 it was acquired by Exco plc in a reverse takeover and the enlarged business was renamed Intercapital plc. Garban plc was established in the 1970s as the financial services division of MAI plc. Several takeovers followed, starting in 1977 when MAI plc acquired Harlow, Meyer and Co. Mallon & Dorney and Garvin GuyButler were acquired by 1982 and in 1983, Garban LLC was acquired giving MAI plc significant broking interests in the UK and overseas. In 1996, MAI plc was merged into United News & Media plc: its financial services division was then de-merged and listed on the London Stock Exchange in 1998 as Garban plc
