The firm also saw sales increase to £33.4m from £30m in its previous results.

The firm’s increase in turnover was better than originally forecast with performance at the company charging ahead of market benchmarks in both core and gluten-free ranges, The Herald reports.

Nairn’s has been investing heavily in expanding its offering in such ranges and in developing new products such as oat bars and pop oat products. In the company’s strategic report, contained within its accounts for the year, directors at Nairn’s stated that the new products offer a healthy alternative in the snacking category.

Nairn’s directors said: “Like many other businesses, the company has faced challenges in the form of continued uncertainty and potential implications from Brexit, further expected cost increases in key ingredients and a challenging domestic retail landscape.”

The directors highlighted, however, that “the company has a specific Brexit risk mitigation plan” to deal with changes in global raw material prices and regulatory changes which may occur.
