According to Reuters, Kazuo Hirai and other Sony officials are open to any solutions, including selling the phone and TV businesses, or establishing joint ventures with other companies.
To be clear, Sony hasn’t talked to anyone about selling its phone business, but, as Reuters reports, the company acknowledges that "no business is forever", and "every segment now needs to understand that Sony can exit businesses."
While selling the phone division would be a drastic measure, entering a joint-venture wouldn’t be a first for Sony. For more than a decade, Sony was in a joint-venture with Ericsson, but, in 2012, it bought off Ericsson’s stake to establish Sony Mobile Communications.
Sony forecasts a $1.9 billion net loss for the current business year, with the phone division being largely responsible for the loss.
Later this year (likely in March), Sony should launch a brand new family of smartphones, including the Xperia Z4, Z4 Compact, and Z4 Ultra. Perhaps these will represent a new beginning for the company? Let's wait and see.
