ON Semiconductor Seeks Bank Amendment to Increase its Financial Flexibility

Intends to Prepay High Cost Bank Debt

PHOENIX, Ariz. – Nov. 29, 2006 – ON Semiconductor Corporation (NASDAQ: ONNN) today announced that it is seeking an amendment of its senior secured credit facility to enable it to replace a significant portion of its bank debt with indebtedness to be incurred outside of the facility, to incur additional junior indebtedness and to permit the expenditure of up to $300 million to repurchase shares of common stock, all subject to market and certain financial conditions. Indebtedness under the senior secured credit facility at September 29, 2006 was approximately $574 million, and the company has prepaid $55 million of that amount during the fourth quarter.

The company also announced today that its board of directors has authorized the company to repurchase up to 50 million shares of common stock from time to time in the open market.

“With our current strong cash position, ongoing cash flow generating capabilities of the business and the availability of lower cost financing, we believe we are in a position to take a number of steps to continue improving our overall financial performance. The proposed changes to our bank facility will allow us to be opportunistic in taking advantage of market conditions.” said Donald Colvin, ON Semiconductor executive vice president and CFO.
