Frontline has its origin in Frontline AB, which was founded in 1985, and which was listed on the Stockholm Stock Exchange from 1989 to 1997. Hemen Holding became the largest shareholder of Frontline in 1996. In May 1997, a decision was made at the general meeting in Frontline AB to change its domicile from Sweden to Bermuda and to list its shares on the Oslo Stock Exchange. The change of domicile was executed through a share for share exchange offer from the then newly formed Frontline in Bermuda.
Under Fredriksen the company absorbed several other companies: London and Overseas Freighters , ICB , and Golden Ocean . These takeovers made Frontline the world's largest tanker company, a position it has retained to the present day.
