SONY CORPORATION (Registrant) By: /s/ Nobuyuki Oneda (Signature) Nobuyuki Oneda Executive Vice President and Chief Financial Officer Date: October 17, 2005 List of materials Documents attached hereto: i)Press release announcing Sony Ericsson Q3 Results Sony Corporation Telefonaktiebolaget LM Ericsson 6-7-35, Kitashinagawa SE-164 83 Stockholm Shinagawa-ku, Tokyo, 141-0001 Japan Sweden PRESS RELEASE October 17, 2005 Hit Models Boost Sony Ericsson Performance Highlights: - Solid growth & market share gain - Increased R&D investment generating expanded portfolio - Strong demand across portfolio The consolidated financial summary for Sony Ericsson Mobile Communications AB (Sony Ericsson) for the third quarter ended September 30, 2005 is as follows: Q3 2004 Q2 2005 Q3 2005 Numbers of units shipped (million) 10.7 11.8 13.8 Sales (EURO m.) 1,678 1,614 2,055 Income before taxes (EURO m.) 136 87 151 Net income (EURO m.) 90 75 104 Units shipped in the quarter reached 13.8 million, a 29% increase compared to the same period last year and a 17% increase sequentially, substantially higher than sequential market growth. Sales for the quarter were Euro 2,055 million, representing a year-on-year increase of 22%. Income before taxes was Euro 151 million and net income was Euro 104 million, which represents a year-on-year increase of Euro 15 million and Euro 14 million respectively. The company continued to increase investment in marketing and R&D to support the expansion of the portfolio going forward. Sony Ericsson began to reap the rewards of earlier increased investment in R&D, expanding the product portfolio with hit models like the K750, the award-winning 2 megapixel, auto-focus camera phone, the first WalkmanTM phone, the W800, which has been exceptionally successful, and the K600 series, which has brought Sony Ericsson UMTS handsets into the mid-tier price category. The company grew faster than the market during the quarter with the popularity of higher-end phones having a positive effect and raising the profile of more affordable, volume models like the T290, J210 and K300. Average Selling Price (ASP) rose during the quarter reflecting the proportion of higher-end products entering the product mix. The global handset market continued to grow faster than expected, and Sony Ericsson is upgrading its global market outlook for 2005 to over 760 million units. "This has been a good quarter for Sony Ericsson, proving that our strategy of expanding the product portfolio upward into best-in-class imaging, music and 3G products while increasing the number of more affordable and attractively designed volume models is paying off. We are increasingly benefiting from the opportunities created by the joint-venture, and with three new Walkman(R) phones shipping in the fourth quarter (W550, W600, W900), we are optimistic that Sony Ericsson can set the standard in music as well as imaging going forward," said Miles Flint, President of Sony Ericsson. Walkman(R) is the registered trademark of 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 Ericsson and Sony in 2001, with headquarters in London, the company employs approximately 5,000 people worldwide, including R&D sites in Europe, Japan, China and America.
