Item 12. Results of Operations and Financial Condition.

The information in this Report, including the Exhibit 99.1 attached hereto, is furnished pursuant to Item 12 of this

Form 8-K. Consequently, it is not deemed “filed” for the purposes of Section 18 of the Securities and Exchange Act of 1934, or otherwise subject to the liabilities of that section. It may only be incorporated by reference in another filing under the Exchange Act or Securities Act of 1933 if such subsequent filing specifically references this Form 8-K.

On October 16, 2003, Advanced Micro Devices, Inc. (the “Company”) announced its results of operations and financial condition as of and for the third quarter ended September 28, 2003 in a press release that is attached hereto as Exhibit 99.1.

The Company’s earnings release contains non-GAAP financial measures. Pursuant to the requirements of Regulation G, the Company has provided reconciliations within the press release of the non-GAAP financial measures to the most directly comparable GAAP financial measures in the text of the press release.

EBITDA is presented in the earnings release. EBITDA was determined by adjusting net loss for interest income, interest expense, income tax, depreciation and amortization. Although EBITDA is not a GAAP financial measure, it is calculated and communicated by the Company because management believes it is of interest to investors and lenders in relation to its overall capital structure and its ability to borrow additional funds.

The Company’s calculation of EBITDA may or may not be consistent with the calculation of this measure by other companies in the same industry. Investors should not view EBITDA as an alternative to the GAAP measures of net income as a measure of performance, or cash flows from operating, investing and financing activities as a measure of liquidity. In addition, EBITDA does not take into account changes in certain assets and liabilities as well as interest and income taxes that can affect cash flows. Management does not intend the presentation of EBITDA to be considered in isolation or as a substitute for results prepared in accordance with GAAP.
