“We are pleased we lowered our operating breakeven point to below $800 million and continued to realize improvements that better position us for growth and a return to profitability,” said Robert J. Rivet, chief financial officer. “Despite the effects of the SARS epidemic and weaker than anticipated channel sales in some of our international markets, we reduced our net loss by 24 percent and increased our gross margin as a result of year-on-year sales growth and effective cost management. Quarter-on-quarter, in spite of a sales decline of $69 million, we still managed to reduce our loss and improve our gross margin.

“Our second quarter operating costs of $769 million compared favorably to $897 million in the second quarter of 2002 and to $840 million in the first quarter of 2003. We increased our positive EBITDA quarter-to-quarter and ended the second quarter with a cash balance of $739 million. In addition, we extended our $200 million revolving line of credit, currently untapped, for four years.

“Our recently introduced AMD Opteron^TM processor for servers and workstations is gaining traction in the marketplace. We look forward to the introduction of AMD Opteron processor-based systems from IBM, Fujitsu Siemens and others in the near future. In addition, our AMD Athlon^TM 64 processor for the desktop and mobile PC sectors remains on schedule for a September launch.

“With the successful launch of a single entity that integrates Fujitsu’s and AMD’s Flash memory operations, we believe we are on target to become the number one provider of Flash memory solutions and are focused on establishing Spansion^TM Flash memory as the pre-eminent brand in the Flash memory market.”

BUSINESS OVERVIEW

PC processor sales of $402 million were up 7 percent year-on-year and decreased by 14 percent from the $468 million reported in the first quarter of 2003. Increased second quarter sales to our Tier One OEM customer base

were more than off-set by a decline in the desktop segment, especially in the Asian and European market geographies, where sales were off significantly.

Initial interest and demand for AMD Opteron processors has been tremendous. End-user installations and testing are producing outstanding results in performance and reduced total cost of ownership. AMD expanded its family of AMD Opteron processors with availability of the new AMD Opteron processor 800 Series, for 4-way and 8-way servers and the 100 Series, for 1-way servers and workstations. During the second quarter, AMD also introduced several new processor offerings including the AMD Athlon XP processor 3200+ for desktop computers, and three new mobile processors designed for both thin-and-light and desktop replacement notebook computers. With the upcoming launch of the AMD Athlon 64 processor on September 23, AMD will introduce the world’s first 64-bit PC processor, providing users superior performance and full binary compatibility with today’s 32-bit applications as well as a seamless migration path to pervasive 64-bit computing.

AMD memory sales of $211 million for the second quarter were down slightly from the $218 million reported in the first quarter of 2003. Year-over-year, memory sales were up 20 percent compared to the $175 million in the second quarter of 2002. While the SARS epidemic caused a decline in demand for cellular handsets and resulted in significantly lower memory sales for AMD in Asia, this decline was almost entirely off-set by increased memory sales in North America and Europe. We continued our share gains in the high-end cellular handset market and maintained our leadership position in high density Flash. Bit shipments grew for the seventh consecutive quarter, once again to record levels. Our average Flash density nearly doubled compared to the second quarter of 2002.

In March, AMD signed an MOU with Fujitsu to consolidate the two companies’ Flash memory operations into a single entity. The two companies recently completed the transaction and announced the formation of a new Flash memory semiconductor company, owned 60 percent by AMD, that markets its solutions under the Spansion brand. As a result of the

consolidation of FASL LLC, at the start of the third quarter AMD’s consolidated balance sheet will take on incremental assets and liabilities of approximately $1 billion, which includes $180 million in cash and $190 million in debt. With state-of-the-art wafer fab facilities, leading edge process technology, innovative product design, approximately 7,000 employees and total assets of nearly $3 billion, we believe the company will be the world’s number one Flash memory provider.

CAUTIONARY STATEMENT

This release contains forward-looking statements, which are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Investors are cautioned that forward-looking statements in this release involve risks and uncertainty that could cause actual results to differ materially from current expectations. Risks include the possibility that global business and economic conditions will worsen resulting in lower than currently expected sales in the third quarter of 2003; that Intel Corporation’s pricing, marketing programs, product bundling, new product introductions or other activities targeting the company’s processor business will prevent attainment of the company’s current PC processor sales plans; that demand for personal computers and, in turn, demand for the company’s PC processors will be lower than currently expected; that the sales of AMD PC processors will not follow seasonal patterns or worse in the third quarter despite the availability of a richer mix of the company’s products; that demand for the company’s Flash memory products will be lower than currently expected, particularly in the high-end cellular telephone sector; that we will not be successful integrating the Flash operations of FASL LLC, or be able to achieve or sustain any benefit from its creation; that the company will not achieve sequential growth in sales of Flash memory devices; that the company may not achieve its current product and technology introduction schedules including the current schedule for introducing the AMD Athlon 64 processor, or the schedule for implementing 90nm process technology in Fab 30. We urge investors to review in detail the risks and uncertainties in the company’s Securities and Exchange Commission filings, including but not limited to the Annual Report on Form 10-K for the year ended December 29, 2002, and the Quarterly Report on Form 10-Q for the quarter ended March 30, 2003.
