EXHIBIT 99.1 [AMD Letterhead] CONTACT: John Greenagel Corporate Communications (408) 749-3310 Toni Beckham Investor Relations (408) 749-3127 AMD SAYS FOURTH-QUARTER OPERATING RESULTS COULD BE BREAK-EVEN BASED ON STRONG DEMAND SUNNYVALE, CA - November 11, 1999 - With strong demand for Flash memory products and microprocessors, AMD today announced that it currently expects to achieve revenues of more than $800 million in the current quarter. The company currently forecasts that its goal of achieving break-even operating results in the current quarter is attainable, barring unforeseen events or disruptions in the supply chain. While motherboard availability remains an issue, the company believes that its goal of shipping 800,000 AMD Athlon processors in the current quarter is increasingly realistic. At an analyst meeting at company headquarters in Sunnyvale, California, Chairman and Chief Executive Officer W.J. Sanders III said the company had sold out its Flash memory availability for the current quarter, and that he expects that the company will achieve $250 million in sales of Flash memory devices in the current quarter. Based on presently available information, the company expects that an imbalance of supply and demand in Flash memories will continue for the foreseeable future. Sanders also said that he expects AMD will ship more than 5 million processors for PCs in the current quarter, including both AMD-K6 family processors and AMD Athlon processors. All AMD Athlon processor wafer starts are now on 180-nanometer (0.18-micron) technology, enabling production of higher- frequency devices. Sanders said the company will begin shipments of 750MHz AMD Athlon processors this quarter, and he expects AMD will begin shipments of 800MHz AMD Athlon processors in the first quarter of 2000.
