Jardine Matheson took a minority interest in Gammon in 1969 and it became a public company in 1970. Then in 1975, Jardines acquired the remaining shareholding and thus Gammon became a wholly owned subsidiary of Jardines.[3] In late 1983 Jardine Matheson sold 50 percent of Gammon to Trafalgar House, a UK based company involved in construction, shipping and property.[4]
