Burger King has today unveiled a 0.7% decline in global like-for-like sales as it reported that fourth quarter profits had slumped by 17% to $49m, off the back of falling sales and increased costs. It was the fifth consecutive drop in like-for-like sales for the fast food operator, as it also revealed that the key performance indicator was down by 1.5% in the USA and Canada. However it was an improvement on the –2.4% fall in its fourth quarter last year. For the full year, Burger King earned $186.8m, or $1.36 per share – 7% from last year's net income of $ 200m. Full-year revenue slipped 1% to $2.50bn. Worldwide restaurant margins fell to 10.7% from 12.5%, mostly on higher costs for food and paper costs, said the operator. In the USA and Canada, the figure declined to 11.7% from 13.5%. John Chidsey, Burger King’s chairman and chief executive, said: "In fiscal year 2010, we faced sustained levels of high unemployment and a fragile global economy that combined made this one of the toughest operating environments in recent history.” He added the group was “laser focused” on its operations in the US – where it is revamping its breakfast offering and attempting to steer consumers away from its value menu items. Chidsey added: “"Going forward, we believe we are well-positioned to further expand our global footprint and continue to invest in our re-imaging program. "There is great enthusiasm in the system around our 20/20 design and we have rolled out an attractive development and re-imaging incentive program for our franchisees in select key markets.”
