SONY CORPORATION (Registrant) By: /s/ Nobuyuki Oneda (Signature) Nobuyuki Oneda Executive Vice President and Chief Financial Officer Date: January 18, 2006 List of materials Documents attached hereto: i) Press release announcing Sony Ericsson Q4 Results Sony Corporation Telefonaktiebolaget LM Ericsson 6-7-35, Kitashinagawa SE-164 83 Stockholm Shinagawa-ku, Tokyo, 141-0001 Japan Sweden PRESS RELEASE January 18, 2006 Sony Ericsson reports record shipments, sales and profits Highlights: - Record year due to strong 2H 2005 - 3 million Walkman(R) phones shipped since launch - Further strengthened portfolio with 3G and entry level handsets The consolidated financial summary for Sony Ericsson Mobile Communications AB (Sony Ericsson) for the fourth quarter ended December 31, 2005 and full-year 2005 are as follows: Q4 2004 Q3 2005 Q4 2005 2004 2005 Numbers of units shipped (million) 12.6 13.8 16.1 42.3 51.2 Sales (EURO m.) 2,005 2,055 2,310 6,525 7,268 Income before taxes (EURO m.) 140 151 206 486 514 Net income (EURO m.) 55 104 144 316 356 Units shipped in the quarter reached 16.1 million, a 28% increase compared to the same period last year and a 17% increase sequentially, in-line with the sequential growth in the market. Sales for the quarter were Euro 2,310 million, representing a year-on-year increase of 15%. Income before taxes was Euro 206 million and net income was Euro 144 million, which represents a year-on-year increase of Euro 66 million and Euro 89 million respectively. The fourth quarter witnessed very strong sequential market growth which Sony Ericsson matched, resulting in a record quarter in terms of volumes, sales and net income for the company. The second half of 2005 was particularly strong due to the success of hit model phones in both the imaging and music product categories. A highlight of Sony Ericsson's year was the global success of Walkman branded music phones such as the W800, W600, W550 and the W900, which have established Sony Ericsson at the forefront of expanding consumer choice in how people enjoy digital music on the move. Since the first Walkman phone was launched in volume in August, Sony Ericsson has shipped 3 million Walkman branded units. "This was another solid quarter for Sony Ericsson, and has enabled us to finish the year with great momentum. We are now seeing the benefit of our earlier investments in R&D which have enabled us to expand the product line-up and successfully appeal to new consumers with products like the Walkman phone series. At the same time, investment in developing the Sony Ericsson brand during 2005 is increasingly supporting our position in the market place," said Miles Flint, President of Sony Ericsson. "In the fourth quarter we continued to announce exciting new products at a variety of price points; from high-end 3G products like the new W900 3G Walkman phone to attractive mid-tier clamshell phones like the Z520 model to lower-priced essential phone models such as the J230, J210 and Z300 that will appeal to consumers who want a simple and stylish handset." During the fourth quarter Sony Ericsson announced an approximately $14 million investment to purchase a controlling 64.5% stake in Beijing Suohong Electronics Co, Ltd (BSE) from Sony China, in order to strengthen its in-house manufacturing processes. Sony Ericsson's majority ownership in BSE will be consolidated into Sony Ericsson from the first quarter of 2006. Walkman(R) is the registered trademark of the Sony Corporation. Sony Ericsson Mobile Communications serves the global communications market with innovative and feature-rich mobile phones, accessories, PC-cards and M2M solutions. Established as a joint venture by Sony and Ericsson in 2001, with global corporate functions located in London, the company employs approximately 5,000 people worldwide, including R&D sites in Europe, Japan, China and America.
