Comba Telecom Systems Holdings Limited provided earnings guidance for the six months ended 30 June 2018. Based on the preliminary review of the unaudited consolidated management accounts of the Group for the six months ended 30 June 2018, the Group is expected to record a significant drop in the consolidated net profit for the Current Period as compared with the consolidated net profit for the six months ended 30 June 2017. The drop in the Group's consolidated net profit for the Current Period was primarily attributable to the following factors: The Group increased the relevant investment in the research and development in order to well prepare for the launch of the 5G network, which led to an increase in research and development costs; and the turnover of the Group fell, due to a decrease in related products' demand as leading operators in the mainland China had reduced their capital expenditures and delayed some projects during the Current Period.
