TOKYO, Feb 12 (Reuters) - SoftBank Corp, which runs Japan's third-largest mobile carrier by subscriber numbers, reported a 13.4 percent fall in third-quarter net profit on Wednesday because of an increase in sales costs.
SoftBank now owns stakes in over 1,000 mobile-related enterprises, adding to its empire this fiscal year with purchases including U.S. No.3 carrier Sprint Corp, U.S. handset distributor Brightstar, and Japanese app developer Gungho Online Entertainment Inc.
In October-December, SoftBank's net profit reached 97.25 billion yen ($949.89 million) from 112.28 billion yen a year earlier, the company said in a statement.
Shares of SoftBank closed 0.2 percent lower ahead of the earnings release compared with a 0.6 percent rise in the benchmark stock index.
