KT Corp. said Tuesday that it swung to a net loss in the second quarter from a year earlier, apparently due to falling returns from its traditional fixed-line business and expenditures from its restructuring program in April.

The net loss came to 757.2 billion won ($738 million) in the April-June period, compared to a net profit of 133.3 billion won a year ago, the country’s No. 2 mobile carrier said in a regulatory filing.

The company also posted a net loss of 40.9 billion won in the first quarter.

Revenue edged up 2.4 percent on-year to 5.89 trillion won in the second quarter, while the company posted an operating loss of 813 billion won.

In 2013, the company posted a net profit of 181 billion won, down 83.6 percent from the previous year. Revenue fell 0.2 percent to 23.8 trillion won over the cited period, while operating profit shed 27.7 percent to 873.9 billion won. (Yonhap)
