Donegal Investment Group plc (DIG), formally Donegal Creameries, has reported sales of €86.8m for 2013, an increase of 8.1% from the previous year. Adjusted operating profit increased by 59.2%, from €1.8m to €2.9m.

Donegal, who sold its liquid milk business to Aurivo in 2011, said the results reflected the company’s new strategy, with the group now focused on a streamlined set of businesses, with its seed potato business at the core. The group was renamed Donegal Investment Group in 2013. The company’s produce division, which comprises the seed potato business Irish Potato Marketing (IPM), accounted for 39% of group revenue, with sales of €33.9m in 2013.

Operating profit for the produce division was €1.8m, an increase of 91.7%.
