million and net income was Euro 55 million, which represent year-on-year
improvements of Euro 94 million (204%) and Euro 12 million (28%) respectively.

The company experienced a strong quarter led by consumer demand for the V800
series and Z1010 3G UMTS phones, as well as GSM models like the S700, K700 and
K500 series. During the quarter Sony Ericsson increased investment in brand and
product development, while the Average Selling Price (ASP), one of the highest 
in the industry, increased sequentially to Euro 160.

"2004 was a good year for Sony Ericsson as the company established profitability
and entered into a growth phase in its development," said Miles Flint, President
of Sony Ericsson. "The fourth quarter continued a trend of expansion in both
volume and sales, showing the company's ability to effectively compete in this
dynamic market. Strong growth in Q4 was led by good up-take of our latest 3G
UMTS phone which has laid the groundwork for future expansion of our 3G

During the fourth quarter, Sony Ericsson launched a new entry-level GSM product,
the J200, for the Asia Pacific and Chinese markets, and introduced the Vodafone
V800 and V802SE UMTS phones for the global and Japanese markets. The company
also announced the entry-level T290 which will start shipping globally during 
Q1 and signed an agreement with Sharp Corporation in relation to the 
co-development of 3G FOMA(R) base software for NTT DoCoMo(2) in Japan. In 
addition, Sony Ericsson announced a major global sports sponsorship with the
