DPA Brazil had been held for sale in Fonterra’s financial statements since January 2020.
Fonterra and Nestlé created DPA in 2003 to manufacture and commercialise dairy products throughout Latin America.
In 2014, the joint venture refocused its activities on Brazil and chilled dairy.
Fonterra holds a 51 per cent stake and Nestlé 49 per cent.
DPA operates two plants and employs 1,300 people.
Nestlé, Chamyto, Ninho, Chandelle, Chambinho, Neston and Molico are among the well-known brands DPA marketed in Brazil.
The sale is subject to receipt of regulatory approvals from competition authorities.
Fonterra’s previously announced 2023 earnings guidance will still reflect the underlying performance of the DPA Brazil business during the pre-completion period.
The co-op said it would provide an update on the overall impact of its divestment programme as part of its 2023 financial reporting.
