SILENT SWEDISH PARTNER
The impetus may come instead from partner Ericsson, which could push Sony to buy it out if their joint venture continues to fade in relevance.Sony Ericsson finally turned a profit last year, but that may not last, given the odds currently stacked against it.
"I think it (Sony Ericsson) is already fairly irrelevant in the market in terms of volumes and even value market share," said WestLB's Thomas Langer.
However, Ericsson has no urgent need for the 1 billion to 2.5 billion euros some analysts reckon half of Sony Ericsson's equity is worth, based on its revenues of 6.3 billion euros.
Debt would not be an issue, since the venture had net debt of only 5 million euros at the end of March.
Meanwhile, Ericsson's own core business is soaring as telecom operators raise spending to boost capacity in networks choked by smartphone customers.
It has also made joint ventures part of its targets for the 2010-2013 period, possibly signalling no sale is on the cards.
Even if Sony Ericsson does sort out its ownership issues, the going will be tough.
The smartphone market is growing fast, with shipments nearly doubling year on year in the first quarter to 100 million handsets, according to IDC's mobile phone tracker report.
But competition for a larger slice of the pie is fierce, and Sony Ericsson will not only have to battle deep-pocketed, larger rivals like Samsung Electronics , but also nimbler Asian players such as HTC, China's ZTE and Huawei.
Sony Ericsson has 9 percent of the market for smartphones running on Android software, compared with 26 percent for Samsung, according to researcher Strategy Analytics.
Eight analysts polled by Reuters all thought Sony Ericsson would likely miss its target of becoming the biggest seller of Android.
