Sam Woo Construction Group Limited provided group earnings guidance for the six months ended 30 September 2016. Based on currently available information, the group expects a substantial drop in profits for the six months ended 30 September 2016 of not less than 60% as compared to that of the corresponding period last year. The decrease was mainly due to decrease in contract revenue and decline in the overall profit margin of the projects undertaken by the group as compared with those projects in the corresponding period last year.
