MICRON TECHNOLOGY INC Segments Disclosure
Segment and Other Information
We initiated a strategic reorganization of our business units to a market segment-focused business unit structure, with AI growth opportunities in every business unit. We completed the reorganization of our operations and organizational structure and began to manage operations under our new segment structure effective in the fourth quarter of 2025. As high-performance memory and storage become increasingly vital to drive the growth of AI, this business unit reorganization allows us to stay at the forefront of innovation in each market segment through deeper customer engagement and to address the dynamic needs of the industry.
All prior-period segment amounts have been retrospectively adjusted to reflect the way our Chief Executive Officer, who is our Chief Operating Decision Maker (“CODM”), assesses the performance of our segments based on segment revenue, cost of goods sold, operating expenses, and operating income (loss). The segment information reported herein is regularly provided to and reviewed and evaluated by our CODM to budget, forecast, and decide how to allocate resources for capital investments, human capital, and other strategic investments across our segments. There are no changes to our Consolidated Financial Statements for any prior periods.
We have the following four business units, which are our reportable segments:
•Cloud Memory Business Unit (“CMBU”): Focused on memory solutions for large hyperscale cloud customers, and HBM for all data center customers.
•Core Data Center Business Unit (“CDBU”): Focused on memory solutions for mid-tier cloud, enterprise, and OEM data center customers and storage solutions for all data center customers.
•Mobile and Client Business Unit (“MCBU”): Focused on memory and storage solutions for the mobile and client segments.
•Automotive and Embedded Business Unit (“AEBU”): Focused on memory and storage solutions for the automotive, industrial, and consumer segments.
Our other operations do not meet the thresholds of a reportable segment and are reported under All Other. Certain operating expenses directly associated with the activities of a specific segment are charged to that segment. Other indirect operating income and expenses are generally allocated to segments based on their respective percentage of cost of goods sold or forecasted wafer production. Certain income and expenses are not allocated to segments because our CODM does not consider these amounts in the assessment of the performance of our segments. The unallocated amounts primarily include stock-based compensation, the impact of inventory NRV write-downs, gains and losses from settlements, restructure and asset impairment, and goodwill impairment.

We do not identify or report internally our assets (other than goodwill) or capital expenditures by segment, nor do we allocate gains and losses from equity method investments, interest, other non-operating income or expense items, or taxes to segments.
As a result of reorganizing our segments in the fourth quarter of 2025, we reallocated goodwill among our reporting units on a relative fair value basis. We performed a quantitative goodwill impairment assessment for each of our reporting units immediately before and after our business unit reorganization. We concluded based on both our pre- and post-reorganization impairment assessments that goodwill was not impaired. As of August 28, 2025, CMBU, CDBU, MCBU, and AEBU had goodwill of $654 million, $109 million, $284 million, and $103 million, respectively.
We performed a qualitative assessment for goodwill impairment in 2024 and did not identify any impairment indicators for our reporting units. Due to global and macroeconomic challenges, as well as lower expected demand resulting from customer actions to reduce elevated inventory levels, in 2023, we performed a quantitative assessment for goodwill impairment for each of our reporting units. We evaluated the fair value of our reporting units based on an income approach, using a discounted cash flow methodology. We recognized a $101 million charge in 2023, included in other operating income (loss) to impair all of the goodwill assigned to our former Storage Business Unit based on our best estimates of projected future cash flows at that time.

About Segments Disclosures
Segment disclosures break a company into its reportable operating units, revealing revenue, profit, and asset allocation that consolidated financial statements obscure. Under ASC 280, segments must match how the chief operating decision maker views the business, providing a window into internal management structure and resource allocation priorities.
Key signals: compare segment margins to identify which units drive profitability and which destroy value. Watch for changes in the number of reportable segments — segment aggregation or disaggregation often coincides with strategic shifts or attempts to obscure declining performance. Intersegment elimination patterns reveal internal pricing practices. The reconciliation between segment totals and consolidated figures exposes corporate overhead allocation and unallocated items. Geographic revenue concentration highlights regulatory and currency exposure. Compare segment-level capital expenditure against segment revenue to assess where management is investing for future growth versus harvesting existing assets.
