The state-controlled National Union Engineering Consultants, which is listed on Libya's stock market, held assets of LD10.6bn ($8.3bn) at the end of the first quarter but recorded a sizable loss.
Figures released by Libya's stock market regulator in early August revealed that the company made a loss of LD652m ($513m) during the first half of the year.
It said these figures had not been verified by an external auditor.
National Union Consultants is a subsidiary of the government-controlled National Union Holding and undertakes engineering, design and feasibility studies, project management and related services across the construction and real estate industry, principally on public-sector projects.
