Saudi Electricity Co said on Wednesday its first quarter net loss narrowed by 25 percent, thanks to increased revenue, beating the market forecast.
The firm recorded a net loss of SR583m ($155m) compared with a loss of SR774m in the same period of last year, it said in a statement.
Three analysts surveyed by Reuters had on average forecast a loss of SR814m.
The company attributed the improved performance to increased revenue from higher energy sales.
