Canadian acquisition solidifies ON Semiconductor as a leading supplier of ultra-low-power DSP technology for hearing aids and audio processing applications

PHOENIX, Ariz. – June 9, 2010 – ON Semiconductor Corporation (Nasdaq: ONNN) a premier supplier of high performance, energy efficient silicon solutions for green electronics, today announced it has acquired privately held Sound Design Technologies, Ltd. (SDT) from an affiliate of Global Equity Capital, LLC, in an all cash transaction for initial consideration of approximately $22 million.

Under the terms of the acquisition, the seller will also have the ability to receive additional earn-out proceeds of up to $10 million if, among other things, SDT is able to meet certain revenue thresholds in 2010, 2011 and 2012. The initial consideration value represents approximately one times SDT’s first quarter 2010 annualized sales levels. SDT will now become an integrated part of ON Semiconductor’s Medical Division, based in Waterloo, Ontario, Canada.

“The acquisition of Sound Design Technologies solidifies our position as a leading supplier of ultra-low-power digital signal processing (DSP) technology for hearing aids and audio processing applications,” said Robert Tong, vice president of ON Semiconductor’s Medical Division. “In addition, the acquisition strengthens the company’s talent base and adds an experienced design and applications engineering team for the audiology segment. SDT’s advanced manufacturing expertise in chip-scale capacitors and high density packaging will also expand our capabilities in delivering advanced, highly miniaturized packaging technology, crucial for hearing aid and similarly size-constrained applications that demand medical-grade quality.”

Michael Hirano, executive vice president, operations of Global Equity Capital, stated, “Matching SDT’s cutting edge technology with ON Semiconductor’s worldwide presence and industry expertise is a natural next step in the evolution of the business, also benefiting SDT customers building sophisticated hearing products.”

SDT is a leading designer and manufacturer of ultra-low-power semiconductor solutions for hearing aids and portable, battery-powered DSP applications, and a leading provider of advanced high density interconnect technologies used in custom miniaturized packages. Based in Burlington, Ontario, Canada, SDT has a 37-year history of innovation in developing miniaturized audio processors. The hearing instrument products and manufacturing operations of Gennum Corporation were acquired in 2007 to form SDT. For more information, visit www.sounddesigntechnologies.com.
