Kazuo Hirai looks set to end his six-year reign at Sony Corp. on a high note.

The electronics giant said Friday its president and chief executive officer credited for turning around the once-struggling company will assume chairmanship and be replaced by his right-hand man.

The announcement came as Sony posted a nearly fourfold jump in third quarter operating profit and raised its full year profit forecast to a record high, underscoring how a restructuring drive led by Hirai, focusing on image sensors and gaming, is reaping rewards.
