SONY CORPORATION (Registrant) By: /s/ Nobuyuki Oneda (Signature) Nobuyuki Oneda Executive Vice President and Chief Financial Officer Date: April 13, 2006 List of materials Documents attached hereto: i) A press release announcing - Sony Ericsson Q1 Results SONY ERICSSON Sony Corporation Telefonaktiebolaget LM Ericsson 6-7-35, Kitashinagawa SE-164 83 Stockholm Shinagawa-ku, Tokyo, 141-0001 Japan Sweden PRESS RELEASE April 13, 2006 Greater depth in portfolio contributes to strong growth Q1 Highlights: - Strong sales & volume growth - Expansion of portfolio at all price points - Income before tax Euro 151 million - 115% year-on-year increase The consolidated financial summary for Sony Ericsson Mobile Communications AB (Sony Ericsson) for the first quarter ended March 31, 2006 is as follows: Q1 2005 Q4 2005 Q1 2006 Numbers of units shipped (million) 9.4 16.1 13.3 Sales (EURO m.) 1289 2310 1992 Income before taxes (EURO m.) 70 206 151 Net income (EURO m.) 32 144 109 Units shipped in the quarter reached 13.3 million, a 41% increase compared to the same period last year, higher than general market growth but down 17% sequentially. Sales for the quarter were Euro 1,992 million, representing a year-on-year increase of 55%. Income before taxes was Euro 151 million, which represents a year-on-year increase of 115%. Net income more than tripled year-on- year to Euro 109 million. Earlier increases in R&D investment enabled Sony Ericsson to announce more new products during the first quarter than in previous years. These products included a further three Walkman(R) phones; the tri-band edge W810, the high-end W950 with 4GB flash memory, and the mass market W300 clamshell. Building upon the success of bringing Sony's very popular Walkman(R) brand to the mobile phone, Sony Ericsson also announced the K800 and K790, flagship 3.2 megapixel imaging phones and the first Cyber-shot TM branded phones in the portfolio. Average Selling Price (ASP) rose 4% to Euro 149, reflecting the greater proportion of higher-end products entering the product mix due to the new phones for both KDDI and NTT DoCoMo in Japan. In GSM markets a number of lower priced handsets such as the Z300, J230, J220 started to ramp up and ship. In Japan, NTT DoCoMo announced and started shipping Sony Ericsson's first FOMA TM phone, the SO902i, and KDDI launched the W41S, an EV-DO handset with Sony's FeliCa* multi-purpose IC card technology. Growth in the global handset market continued to outpace earlier expectations, and Sony Ericsson now forecasts the global market outlook for 2006 to be over 900 million units. Our previous guidance was 10% growth versus estimated 2005 market volumes of about 780 million units. In March, Sony Ericsson strengthened its strategy of focusing on compelling consumer mobile solutions through innovative mobile phones, accessories and PC cards by signing an agreement to sell its business-to-business Telemetry and Automotive M2M business units to Wavecom. "The first quarter has seen Sony Ericsson announce a host of exciting products which address a wide variety of consumer needs and lifestyle choices. We have announced flagship models in our three key strategic areas: music, imaging and enterprise, and feel well positioned to deliver an enhanced user experience at all price points of our portfolio. The W800, W550 and W600 Walkman(R) phones were big sellers during the quarter and we have now sold 5.5 million Walkman(R) branded phones since mid-August, proving the success of our mobile music strategy. With a total of eight Walkman(R) phones now announced or shipping, plus the introduction of new Cyber-shot TM imaging phones, we are beginning to deliver the differentiation in our product portfolio which Sony Ericsson promised at the start of the joint venture," said Miles Flint, President of Sony Ericsson. The Shareholders decided on a dividend of Euro 247 million paid to the parent companies on March 30, 2006. FOMA TM is a trademark of NTT DoCoMo, Inc. in Japan and other countries. *FeliCa is Sony's contactless IC card technology, providing advantage of multi-applications in a single card, as well as high security features and processing speed. WALKMAN(R) and Cyber-shot TM are registered trademarks of Sony Corporation.
