Ahold "has reached an agreement with Hakon Invest regarding the sale of Ahold's 60 percent holding in Ica, the Scandinavian retailer, for 21.2 billion kronor," the company said in a statement.
The deal included Ica's 2012 dividend of 1.2 billion kronor.
In conjunction with the announcement of the deal, Ica also released its quarterly results, reporting profit of 812 million kronor before tax for the fourth quarter of last year - compared to 853 million kronor in the corresponding period from 2011.
Anders Nyrén, CEO of Industrivärden, praised the move by Hakon Invest.
"Ica is a very strong brand, and the company has shown good volume growth and rising margins over a number of years," he said in a statement.
The deal is contingent upon regulatory approval and is predicted to be completed in April this year.
Hakon Invest has owned part of Ica since 2000, when it bought its share in the company together with Royal Ahold.
