Expert Systems Holdings Limited provided earnings guidance for the nine months ended December 31, 2016. Based on the information currently available to the board, the Group is estimated to record a substantial increase in reported net profit for the nine months ended 31 December 2016, as compared to that of the corresponding period of 2015. Based on the information currently available, the estimated substantial increase in reported net profit of the group for third quarter of fiscal year 2017 as compared to third quarter of fiscal year 2016 is mainly attributable to the substantial decrease in administrative expenses for third quarter of fiscal year 2017 as compared to third quarter of fiscal year 2016 mainly due to the non-recurring listing-related expenses of approximately HKD 9.3 million incurred in third quarter of fiscal year 2016 while no such expenses were incurred in third quarter of fiscal year 2017. However, after adjustment by adding back the said non-recurring listing-related expenses incurred in third quarter of fiscal year 2016, the Group is estimated to record a substantial decrease in underlying net profit (representing reported net profit adjusted for non-recurring expenses/gains, if any) for third quarter of fiscal year 2017 as compared to third quarter of fiscal year 2016. The estimated decrease in underlying net profit of the Group for third quarter of fiscal year 2017 as compared to that of third quarter of fiscal year 2016 is mainly due to the decrease in gross profit margin during the period as a result of the Group's efforts in maintaining its market share by offering more competitive pricing under the challenging business environment.
