Cohort was formed in 2006 and admitted to London's Alternative Investment Market in March 2006.
Originally formed by Stanley Carter and Nick Prest, sharing a common vision to create a publicly quoted defence technical services business that would be independent, expert, practically oriented, flexible and cost-effective.
The Group’s mission remains as it was when it was founded, to build a group of companies applying advanced technology in defence, security and related markets, and combining the innovation and responsiveness of smaller, independent businesses with the stability, shared knowledge, wider market access and lower funding costs of a listed group, to provide enduring benefits to customers, employees and shareholders.
The founding members of the Group in 2006 were SCS and MASS. SEA joined the Group in 2007, MCL in 2014, EID in 2016, Chess Technologies in 2018 and most recently, in December 2020, ELAC SONAR joined the Group.
