Microchip Technology Announces Acquisition Of Silicon Storage Technology, Inc.

Microchip Technology Incorporated (NASDAQ:MCHP), a leading provider of microcontrollers and analog semiconductors, announced today that it has signed a definitive agreement to acquire Silicon Storage Technology, Inc. (Nasdaq:SSTI) for $2.85 per share in cash. The $2.85 per share represents an approximate 35.7% premium to the amount that the holders of SST common stock would have received under the previously announced merger agreement between SST and Technology Resources Holdings, Inc., and an approximate 53.2% premium to the closing price per share of SST’s stock on November 12, 2009, the last day of trading prior to the announcement of the execution of the definitive merger agreement with Technology Resources Holdings, Inc. As separately announced today by SST, SST has terminated its previously announced merger agreement prior to entering into the definitive agreement with Microchip.

The acquisition has been approved by the Boards of Directors of each company and is expected to close in the second quarter of calendar 2010, subject to approval by SST’s stockholders and other customary closing conditions.

“SST’s Superflash ^® technology and extensive patent portfolio are critical building blocks for advanced microcontrollers,” said Steve Sanghi, President and CEO. “This acquisition enables Microchip to gain earlier access to SST’s advanced technologies, as well as the ability to customize technology variants that can give us an advantage over competing technologies.”

“We believe this is an attractive transaction for SST’s stockholders, as it presents a significant premium to the prior transaction and requires no external financing,” continued Mr. Sanghi. “We look forward to completing this transaction early in the second calendar quarter of 2010.”
