Compared with the Prior Period, the Board is of the view that such expected increase in the Group’s results for the Reporting Period is mainly attributable to the continuous improvement in the total revenue of the Group due to the kick-off of 4G network investment cycle and increased investment in wireless enhancement in Mainland China. In addition, overall gross profit margin has been improved due to the optimization of product mix and the growing revenue contribution by some new and high-end products, and greater economy of scale has been achieved as a result of effective cost control measures. Despite partial contribution was offset by foreign exchange loss, the Group still expects to record a substantial increase in Net Profit during the Reporting Period.

The information and figures contained in this announcement are only based on the unaudited consolidated financial information of the Group for the Reporting Period which have not yet been reviewed or audited by auditors of the Company and may be subject to adjustments.
