The subsidiary of property developer FLC should have furnished the report within 20 days from the end of each quarter but failed to do so for the quarter ending June.
Its ROS stock, along with FLC and HAI Agrochem’s stocks are currently restricted to trading only in the afternoon daily.
ROS was trading at VND16,000 ($0.66) in January but has lost 80 percent after FLC executives were arrested for alleged stock manipulation.
