ON Semiconductor Corp. and SANYO Electric Co. Ltd. announced the signing of a definitive purchase agreement providing for the acquisition of SANYO Semiconductor Co. Ltd., a subsidiary of SANYO Electric, and other assets related to SANYO Electric’s semiconductor business, by ON Semiconductor in a cash and stock transaction with a purchase price of approximately $366 M (¥33.0 B), subject to adjustment pursuant to the terms of the transaction. Based on the most recently completed quarter, SANYO Semiconductor’s annualized revenue was approximately $1.2 B and the annualized revenue of the combined entity would be approximately $3.5 B. The acquisition is expected to be completed before the end of 2010.

Transaction Highlights:

• Highly complementary products, customers and geographic regions

• Expected to provide SANYO Semiconductor customers with access to advanced front-end mixed-signal and analog manufacturing, and ultra high volume back-end facilities

• Expected to provide ON Semiconductor with access to market-leading Japanese and Asian customers

• Significant efficiency gains expected through optimization of manufacturing, process technology platforms and efficient capital investments

• Transaction is expected to be accretive to ON Semiconductor non-GAAP EPS approximately 12 months after closing

“The pending acquisition of SANYO Semiconductor is another significant step by ON Semiconductor to solidify its position as a premier global supplier of high-performance, energy efficient silicon solutions with increased manufacturing scale and an expanded addressable market,” said Keith Jackson, President and CEO of ON Semiconductor. “By combining these two highly complementary businesses, we will be better positioned to capture growth on a global scale. We believe the union of ON Semiconductor and SANYO Semiconductor will greatly enhance our presence in the automotive and consumer end-markets and significantly strengthen our geographic presence in the Asia-Pacific region. Strategically, this acquisition is expected to provide us with increased access to an important part of the global semiconductor market - the Japanese market, where SANYO Semiconductor has a more than 50 year operating history, and a longstanding presence at leading electronics manufacturers.”

This acquisition will expand and strengthen ON Semiconductor’s product portfolio, adding new capabilities ranging from microcontrollers and custom Application Specific Integrated Circuits (ASIC) to integrated power modules and motor control devices for the consumer, automotive and industrial end-markets.

“Having completed seven acquisitions, ON Semiconductor has a proven track record of successfully integrating acquired businesses, and realizing manufacturing and operational efficiencies,” said Jackson. “While ON Semiconductor has had a manufacturing and sales presence in Japan for more than a decade, this acquisition is an exciting move on our part to wholeheartedly enter the Japanese market. Customers of both SANYO Semiconductor and ON Semiconductor will benefit from what will become the combined expertise of talented engineering, manufacturing, sales, service and supply chain teams. We value SANYO Semiconductor’s customer knowledge and understanding, and look forward to building upon these important longstanding relationships. Our goal is to continue the structural transformation efforts begun by SANYO Electric. We welcome SANYO Electric as a shareholder and hope to build a collaborative long-term relationship.”

Teruo Tabata, President of SANYO Semiconductor, added, “There will be no change in the strategy as far as technology is concerned, as both companies specialize in analog technology. Instead, following the acquisition by ON Semiconductor, new opportunities to introduce both companies’ existing products in our newly combined markets will be available. We can also expect to expand the consumer base and further grow the business by offering complementary products and services to each other. In addition, we can expect further business development by strengthening product competitiveness through ON Semiconductor’s superior cost control measures in a value-added supply chain.”
