Transtech Optelecom Science Holdings Limited provided consolidated earnings guidance for the year ended December 31, 2021. The group is expected to record a significant decrease of net profit for the current year by approximately 80% to 85% as compared with the net profit for the year ended 31 December 2020. Based on the information currently available, such expected significant decrease of net profit for the group during the current year was mainly attributable to the effect of the following factors: less revenue made given that the selling price and volume generally decreased because of the outbreak of COVID-19; increase of loss allowance for trade receivables; and less foreign exchange gained resulting from the fluctuation of exchange rates among Renminbi, Thai Baht, United States Dollar and Hong Kong Dollar.
