Although sandwich and food-to-go manufacturer Greencore is concerned about the outlook for the UK economy, it believes the short-term impact on the business is likely to be modest. Supplying half of all the sandwiches sold in the UK, Greencore does not expect the weakening of sterling to affect profits in the current financial year. This is mainly because of forward purchasing arrangements and that less than a quarter of ingredients and packaging materials are imported for the UK businesses.
