Top Standard Corporation reported earnings guidance for the six months ended September 30, 2018. For the period, the company expects to record a net loss as compared to a net profit a year ago. The increase in the cost of raw materials and the additional staff costs paid to the Group's employees due to a higher number of administrative and management personnel of the Group, continued to affect the Group's profitability for the three months ended 30 September 2018, which in turn negatively affected the Group's profitability during the reporting period.
