SoftBank is attempting to return to the black after completing its acquisition of a majority stake in US operator Sprint last year.
According to local Japanese news sources, the company is attempting to implement a number of restructuring measures to help recover subscribers and improve Sprint’s position.
Sprint registered a ¥1.2 billion operating loss in the last fiscal year, according to reports in Japan.
The company is reportedly still in talks with T-Mobile US over a possible merger.
