Food giant 2 Sisters Food Group is investing in biscuit and pizza categories, it has revealed in its Q3 results.

The company saw total like-for-like (LFLs) sales up 1.1% to £798.7m in the 13 weeks ended 2 May 2015, as it gears up to launch new products.

2 Sisters owns the Fox’s Biscuits brand, and said it would invest in marketing and promotions across the biscuit category.

It said it had addressed the cost base of its biscuit business across all functions, which, along with new product launches, will enable the group “to drive benefits later in the year going forward”.

The frozen food category also looked positive, seeing LFL revenue up 2% to £92.5m. The company will invest in its frozen pizza capacity to make way for new product launches.

It has also secured a contract for more retail ranges to launch in November this year.

Chief executive Ranjit Singh said: “This is an encouraging performance and in line with expectations. It underlines our commitment to focus on building a better business, which leads the food sector and is passionate about putting customers and consumers first.

“In our Chilled business, we are looking at further investment in capacity to enable us to meet our growth ambitions, and we can report a good performance by our Branded division.

“All this activity sets a very solid foundation for future growth of the business.”

This comes after 2 Sisters workers at its Gunstones bakery in Sheffield went on a 48-hour strike over pay freezes. Another 48-hour strike is set to take place on 17 and 18 July.
