1 EXHIBIT 99 [ON LOGO] Everett Tackett Dan Martin Director Public Relations Director Investor Relations ON Semiconductor ON Semiconductor (602) 244-4534 (602) 244-4905 everett.tackett@onsemi.com dan.martin@onsemi.com ON SEMICONDUCTOR ANNOUNCES FIRST QUARTER 2001 RESULTS PHOENIX, ARIZ. - APRIL 25, 2001 - ON Semiconductor Corporation (Nasdaq: ONNN) today announced that total product revenues in the first quarter of 2001 were $357.0 million, a decrease of 13% compared to the first quarter of 2000 and a decrease of 24% from the fourth quarter of 2000. Excluding amortization of intangibles, restructuring charges and the cumulative effect of an accounting change, the Company had a net loss of $12.7 million, or ($0.07) per diluted share, in the first quarter of 2001 compared to net income of $10.9 million, or $0.03 per diluted share, in the first quarter of 2000. Including amortization of intangibles, restructuring charges and the cumulative effect of an accounting change, the Company reported a net loss of $159.4 million, or ($0.92) per diluted share, in the first quarter of 2001 compared to net income of $7.9 million, or $0.01 per diluted share, in the first quarter of 2000. Effective January 1, 2001, the Company changed its accounting method for recognizing revenue on shipments to distributors. On that date, the Company began deferring revenues on shipments to distributors until products are resold to end users. The cumulative effect of this change in accounting method was a charge of $116.4 million (net of $38.8 million of income taxes) in the first quarter. For comparative commentary purposes, prior period figures are pro forma as if the change in distributor revenue recognition had been in effect in all periods discussed. Commenting on the accounting change, Dario Sacomani, senior vice president and chief financial officer, said, "Our new method of revenue recognition on shipments to distributors is a more conservative approach. This policy will increase the Company's focus on end user demand and will be an important first step in minimizing future volatility and excess inventory in the supply chain." -more-

2 ON Semiconductor Announces First Quarter 2001 Results 2-2-2-2 As part of cost reduction actions, the Company also incurred restructuring charges of $38.0 million, or $26.8 million on an after-tax basis, in the first quarter of 2001 primarily associated with manufacturing and administrative overhead workforce reductions worldwide. Overall gross margin was 24.0% in the first quarter of 2001, down 7.2 percentage points from the first quarter of 2000 primarily due to lower unit shipments and resulting lower factory utilization. Operating expenses were significantly reduced in the quarter, particularly general and administrative expenses, which were cut 37% from the fourth quarter 2000, as a result of aggressive cost reduction actions. Earnings before interest, taxes, depreciation and amortization, excluding minority interests and restructuring charges in the first quarter of 2001 were $43.5 million, compared to $92.1 million in the first quarter of 2000. "Within this challenging business environment, we continue to stay focused on serving our customers, developing new products and executing on company-wide cost reductions. This continued drive to develop relationships, enrich our product portfolio and improve operational efficiency will strengthen our competitive position to better capitalize on a market upturn," said Steve Hanson, president and chief executive officer. "We are also accelerating several of our supply-chain initiatives with the intent of getting closer to our customers. These efforts will help us to better manage the inventory situation during abrupt changes in the market." For its second quarter outlook, the Company anticipates approximately flat to slightly down sequential revenues with slightly better gross and operating margins as compared to the first quarter of 2001 as the Company begins to realize the impact of cost reduction actions taken in the first quarter.
