Nando's, the peri peri chicken restaurant chain, has reported that, in the 36 weeks up to February 2009, it made a loss of £23m. However the group, which is led by chief executive David Niven, said it was “satisfied” with the company’s progress after achieving sales of £167m, according to recently filed accounts with Companies House. It is thought that the losses stem partly from an aggressive opening programme that has seen the company adding up to 30 restaurants per year. It said the losses were also impacted by the rising costs of raw ingredients and slower consumer spending. It also said that it expected to improve its margins this year. Nando's has plans to open 20 new restaurants this year to add to its 220 existing sites.
