1 EXHIBIT 99 FOR IMMEDIATE RELEASE Dan Martin Linda Capcara Director Investor Relations Group Manager ON Semiconductor Brodeur Worldwide 602-244-4905 602-954-0044 dan.martin@onsemi.com lcapcara@brodeur.com - -------------------------------------------------------------------- SCG HOLDING CORPORATION IS NOW OFFICIALLY ON SEMICONDUCTOR CORPORATION PHOENIX, AZ (AUGUST 9, 2000) - ON Semiconductor(TM) (Nasdaq: ONNN) today announced that the official name of the Company has changed to ON Semiconductor Corporation from SCG Holding Corporation, effective today, August 9, 2000. SCG Holding Corporation has been doing business under the trade name ON Semiconductor(TM) since its separation from Motorola in August 1999. The Company's Board of Directors approved the official name change for several reasons including the desire to have its company name more closely parallel its ticker symbol of ONNN on the Nasdaq National Market as well as for branding and marketing purposes. Effective with the name change, the Company began reporting financial information as ON Semiconductor Corporation. "While most of our customers and stockholders have known us as 'ON Semiconductor' since we started as an independent organization last year, our legal name was SCG Holding Corporation," said Steve Hanson, President and Chief Executive Officer of ON Semiconductor Corporation. "Today's announcement makes it official. We are ON Semiconductor Corporation - a company committed to providing our customers with the highest quality data and power management semiconductors." The only entity affected by this name change at this time is SCG Holding Corporation. The legal names of the company's various domestic and foreign operating subsidiaries remain the same and all will continue to do business under the trade name of ON Semiconductor(TM). ON Semiconductor Corporation anticipates that starting tomorrow, the Nasdaq National Market will recognize its new name for listing purposes.
