McDonald’s has reported better than expected sales in Q4 of 2015, boosted by the launch of all-day breakfasts in the US.

The fast food giant extended US breakfasts beyond 10:30am in October 2015, saying it was customers’ number one request.

The company, working to turnaround its business under chief executive Steve Easterbrook, said the breakfast change helped US sales grow 5.7%.

Q4 revenue fell 4% to $6.4 billion due to the strong dollar, but profits rose 10% to $1.2 billion, McDonald’s said.

Steve Easterbrook, who was appointed a year ago, said: “We took bold, urgent action in 2015 to reset the business and position McDonald’s to deliver sustained profitable growth.”

McDonald’s said sales in its “high growth” markets, which include Russia and China, rose 3%.
