Softbank Corp. said Tuesday it posted a 63.0 percent rise in group net profit to ¥94.86 billion in the April-December period from a year earlier due to brisk cell phone business.

In an earnings statement for the first three quarters of fiscal 2009, Softbank said its group operating profit grew 33.4 percent to ¥366.32 billion and pretax profit rose 61.1 percent to ¥281.19 billion.

Sales increased 3.2 percent to ¥2.05 trillion, according to the parent of Softbank Mobile Corp.

Softbank said the result was attributable to the increased number of subscription contracts for mobile phone services and the expanded use of data communications services.

For the whole of fiscal 2009 ending in March, Softbank forecasts a group operating profit of ¥420 billion, up 16.9 percent from the previous year.
