Sony Ericsson sees moderating growth of mobile phone units with related effects
on sales and profit in the first quarter 2008

Sony Ericsson Mobile Communications AB ("Sony Ericsson"), an equity affiliate of
Sony Corporation ("Sony"), today announces that moderating sales growth of
mobile phone units is expected to negatively impact net sales and net income
before tax for the first quarter of 2008. Please refer to the attached press
release for details.

At this time, Sony has no plan to revise its equity in net income of affiliated
companies forecast of 100 billion yen for the fiscal year ending March 31, 2008
on a consolidated basis as announced on January 31, 2008.

Press Release                                                      19 March 2008


Sony Ericsson sees moderating growth of mobile phone units with related effects
on sales and profit in the first quarter 2008

London, UK - Sony Ericsson Mobile Communications AB ("Sony Ericsson") today
announces that moderating sales growth of mobile phone units is expected to
negatively impact net sales and net income before tax ("NIBT") for the first
quarter of 2008. Slowing market growth of mid-to-high end phones in markets
where Sony Ericsson has a strong presence is affecting sales. In addition,
certain component shortages for popular mid-priced phones have contributed to
modest unit sales growth in the first quarter.

"As discussed during our fourth quarter 2007 Media and Analyst Call, the market
is proving to be challenging. This has been more pronounced in the mid-to-high
end replacement sector of the market in Europe, where Sony Ericsson has stronger
than average market share," says Dick Komiyama, President of Sony Ericsson. "For
the last year, Sony Ericsson has been focused on expanding the breadth of its
portfolio and developing its presence in new markets to lessen its historic
reliance on the European high-end sector for growth. This strategy will
continue, and our objective remains to become a top three player globally by
2011. As part of this strategy, we have announced fifteen new phones and
introduced a new platform to the portfolio, Windows Mobile(R), this year. We
expect to start seeing a positive effect from these announcements during the
second half of 2008."

Although final results may differ, Sony Ericsson now plans to ship approximately
22 million phones during the first quarter of 2008 with an estimated ASP
(Average Selling Price) of EUR 120. This is expected to generate net sales lower
than the first quarter of 2007, and NIBT is estimated to be in the range of EUR
150 - 200 million due to increased R&D expenses as a percentage of sales. The
increased investments in R&D are in line with the company's strategy to meet
future growth ambitions. In addition, Sony Ericsson currently expects gross
margin to remain relatively stable for the first quarter of 2008 compared with
the first quarter of 2007.

Sony Ericsson plans to announce first quarter 2008 results on April 23rd.
