Sony is weighing a partial spinoff and separate listing for its financial unit in two to three years, a major decision aimed at bankrolling an investment push in gaming and electronics.

The Tokyo-based company will assess the spinoff plan, which would reverse a $3.7 billion (¥508.5 billion) take-private deal concluded in 2020, over the course of this fiscal year. It would aim to retain just under 20% of Sony Financial Group and sell its shares on a Japanese exchange, the company said in presentation materials accompanying a strategy briefing on Thursday.

Its shares rose as much as 7.3% in Tokyo, their biggest intraday jump in half a year.
