Vivartia was formed by the merger of Delta Holding S.A. and Mechelany International S.A. This merger was the result of a process led by Justin Jenk, the then CEO of Delta Holding, Spyridon Theodoropoulos, majority shareholder of Chipita and Dimitris Daskalopoulos, majority shareholder of Delta. The merged entity became the largest food group in Greece. The merger was the culmination of a highly successful turnaround and improvement strategy put in place by Jenk in 2003. The major shareholder of Vivartia was the Daskalopoulos family until a 76.89% share was sold to the Marfin Investment Group.
