The non-GAAP adjustments above may or may not be infrequent or nonrecurring in nature, but are a result of periodic or non-core operating activities. We believe this non-GAAP information is helpful in understanding trends and in analyzing our operating results and earnings. We are providing this information to investors to assist in performing analysis of our operating results. When evaluating performance and making decisions on how to allocate our resources, management uses this non-GAAP information and believes investors should have access to similar data when making their investment decisions. We believe these non-GAAP financial measures increase transparency by providing investors with useful supplemental information about the financial performance of our business, enabling enhanced comparison of our operating results between periods and with peer companies. The presentation of these adjusted amounts varies from amounts presented in accordance with U.S. GAAP and therefore may not be comparable to amounts reported by other companies. Our management excludes the following items as applicable in analyzing our operating results and understanding trends in our earnings: • Stock-based compensation; • Gains and losses from settlements; • Gains and losses from debt prepayments; • Restructure and asset impairments; and • The estimated tax effects of above, non-cash changes in net deferred income taxes, assessments of tax exposures, certain tax matters related to prior fiscal periods, and significant changes in tax law. The divergence between our GAAP and non-GAAP income tax (provision) benefit relates to the difference in our GAAP and non-GAAP estimated annual effective tax rates, which are computed separately. Non-GAAP diluted shares are adjusted for the impact of additional shares resulting from the exclusion of stock-based compensation from non-GAAP income. 9 MICRON TECHNOLOGY, INC.

The guidance does not incorporate the impact of any potential business combinations, divestitures, additional restructuring activities, balance sheet valuation adjustments, strategic investments, financing transactions, and other significant transactions. The timing and impact of such items are dependent on future events that may be uncertain or outside of our control. 10
