United Energy (00467) said its profit attributable to owners for the six months ended 30 June 2016 dropped 16.1% year-on-year to HK$630 million.
Basic earnings per share were HK4.82 cents.
The turnover from continuing operations was HK$2,196 million, a decrease of 16.5% from a year earlier.
Gross profit fell 4.4% year-on-year to HK$1,275.5 million. The decrease in gross profit was in line with the drop in revenue as a result of weaker international oil price in the reporting period while the scale was significantly offset by the effort in cost control and the increase in production.
No interim dividend will be distributed.
