Clear Media (0100) reported a 15.5 percent fall in net profit to 76.9 million yuan (HK$89.9 million) in the first half of 2017. Total turnover increased 1.8 percent to 762.5 million yuan.
The company said the decrease was partly because some important clients suspended their marketing campaigns in the first quarter.
Chief operating officer Harrison Zhang Huaijun said the price of advertising panels will increase by up to 5 percent this year.
He said the company lost some clients from traditional industries such as food and beverages as they had reduced their costs because of rising prices. However, the number of major clients had increased.
