The deal has yet to be approved by the Romanian Competition Council.
Heidi Chocolat and Kandia Dulce will become sister companies, to be owned by Kex Confectionery, the newly created company said in a press release Monday.
The current management teams of the two companies will remain unchanged.
Heidi Chocolat was set up in 1994 and is a family-owned business. In Romania, it owns a production unit near Bucharest, which employs over 350 people.
Kandia is owned by Austrian group Meinl, after several years of functioning under Cadbury’s umbrella. Last year, Kandia took over Supreme Chocolat, another local producer.
