The record profit in the first quarter is due to accounting profits reflected from the business integration of its messaging firm Line Corp. in Japan with Yahoo Japan.

On March 1, Z Holdings Corp., a parent company of Yahoo Japan, and Line announced the completion of the business integration between the two companies.

Operating income reached 288.8 billion won for the cited period, down 1 percent from the year before. Sales reached 1.49 trillion won during the same period, representing a 29.8 percent increase compared with the year before, Naver said.
