The third-quarter sales and operating profit represent record-breaking quarterly numbers. Net profit came to 275.1 billion won, up 474 percent from the previous year, the company said.

The strong results in the third quarter were in part due to strong performance of the company's mobile games business, including the continued popularity of Lineage M, a mobile version of its mega-hit game "Lineage."

Revenues from the mobile game business came to 551 billion won for the third quarter, the company said, without releasing the revenues from Lineage M.

Accumulated revenues from Lineage M are forecast to have surpassed 600 billion won since its launch in July, market watchers said, with daily revenue estimated at 5.5 billion won.

By region, sales came in at 631 billion won in South Korea, 32.3 billion won in North America, 10.4 billion won in Japan and 9.9 billion won in Taiwan.

Shares of NCsoft were trading at 427,000 won on the Seoul bourse as of 9:40 a.m., down 5.65 percent from a day earlier. The earnings were announced before the local market opened. (Yonhap)
