Sony Ericsson reports continued growth in sales and profit

Tokyo and Stockholm -- Sony and Ericsson today announced the consolidated
financial summary for the third quarter ended September 30, 2004 of Sony
Ericsson Mobile Communications AB (Sony Ericsson), the 50:50 joint venture of
Sony and Ericsson.

Units shipped in the quarter reached 10.7 million, a 51% increase compared to
the same period last year. Sales for the quarter were Euro 1,678 million,
representing a year-on-year increase of 29%. Income before taxes was Euro 136
million and net income was Euro 90 million, which represent year-on-year
improvements of Euro 97 million (249%) and Euro 28 million (45%) respectively.

The company maintained its momentum from the first half of the year, generating
profitable growth. Sony Ericsson's Average Selling Price (ASP) increased
sequentially in line with company expectations due to new mid and high-end
Japanese and GSM products beginning to ship.

"Sony Ericsson has enhanced its portfolio during the quarter with the launch of
exciting products. Over 60% of phones sold during the quarter featured
integrated cameras which illustrates our position as a market leader in mobile
imaging," said Miles Flint, President of Sony Ericsson. "The quarter has seen us
shipping a number of new products such as our first GSM megapixel camera phone,
the S700, the new P910 smartphone and the youth orientated K500 series. In
addition we also announced together with Vodafone the V800, our second 3G UMTS

In Japan the company launched the mova(R) SO506iC for NTT DoCoMo, Sony
Ericsson's first handset with i-mode(R) FeliCa Service for mobile wallet
applications(1) and the W21S, a 3G CDMA 1x EV-DO phone for KDDI.
