"We remain focused on managing the pace of our growth and development of Ted Baker as a global brand," he said.
Ted Baker has 341 stores and concessions worldwide, including 178 in the UK, 60 in Europe, 58 in the US and Canada, 40 in the Middle East and Asia, and five in Australasia.
Chairman David Bernstein said there would be one-off costs in the second half of the year as the business closes stores "that are no longer appropriate for the brand" or relocates outlets.
Cantor analyst Freddie George said profits were at the lower end of expectations due to the higher than expected cost of overseas expansion.
