Micron Technology, Inc. (MU) Business Profile

What it does

Micron Technology is a semiconductor memory and storage company founded in 1978 and headquartered in Boise. Sanjay Mehrotra is its Chairman and Chief Executive Officer. It designs and manufactures chips that hold data temporarily while a system is working and chips that retain data when power is off.

Its main technologies are DRAM, NAND and NOR. DRAM is fast, temporary memory used in data centers, PCs, graphics, mobile devices, industrial equipment and vehicles. NAND is persistent storage used in solid-state drives, smartphones and other devices. NOR provides fast-read storage for software code in automotive, industrial and consumer applications.

Micron sells individual chips, memory modules, wafers, solid-state drives, managed NAND and multi-chip packages. Some system-level products combine NAND with a controller, firmware and, sometimes, DRAM. High-bandwidth memory, or HBM, is stacked DRAM designed to move data at high speed with lower power use for AI and high-performance computing.

The company organizes sales around four markets: cloud memory for hyperscale cloud customers and data-center HBM; core data-center storage and server memory; mobile and client devices; and automotive, industrial and consumer embedded systems. It manufactures in its own facilities and uses subcontractors for some manufacturing processes. It had 61,000 employees in FY2026.

How it makes money

Micron earns revenue by selling memory and storage products into its four business units. Cloud Memory Business Unit sells HBM, DDR, LPDDR and GDDR memory to large hyperscale cloud customers and other data-center customers. Core Data Center Business Unit sells data-center SSDs, NAND components, and DDR memory to OEM, enterprise and NeoCloud customers. Mobile and Client Business Unit sells mobile memory and storage, PC products, consumer DRAM and NAND components. Automotive and Embedded Business Unit sells DRAM, NAND, managed NAND, SSDs and NOR for intelligent-edge applications.

Sales are principally driven by bit shipments and average selling prices. DRAM represented the larger share of FY2026 product revenue, while NAND includes SSDs and component sales. Higher-value products, including HBM, high-capacity server modules and data-center SSDs, affect product mix and manufacturing complexity.

Contracts with some customers are short term. Micron also has strategic customer agreements: multiyear take-or-pay contracts with binding volume commitments. Prices may be fixed or periodically negotiated; most strategic agreements use minimum and maximum pricing bands. Customers provide cash deposits and letters of credit under these agreements. Management said on the call that 26 strategic customer agreements represented over 35% of revenue through 2030, with approximately $150 billion of remaining performance obligations where pricing frameworks are determined.

FY2026 revenue was $133.2 billion; fiscal Q4 2026 revenue was $54.2 billion.

Customers and how it sells

Micron serves large hyperscale cloud companies, other data-center customers, OEM data-center customers, enterprises, NeoCloud providers, smartphone makers, PC makers, automotive customers, industrial customers and channel partners. It works with customers early in product design to incorporate required features and performance characteristics and to meet product-qualification timelines.

The customer base is concentrated: in each of the last three years, approximately one-half of total revenue came from the top ten customers. An undisclosed customer represented 17.0% of revenue in FY2025. The company sells mainly through its direct sales force, supported by worldwide sales and representative offices. It also uses distributors, retailers and independent sales representatives. Distributors hold inventory and may sell competing semiconductor products; Micron also keeps inventory near certain key customers for rapid delivery.

Its manufacturing footprint spans Taiwan, Singapore, Japan, the United States, Malaysia, China and India. Its sales base is worldwide, and its international operations expose it to differing trade rules, tariffs, currency effects and regional conditions. Management said on the call that more than 75% of 2027 output was already committed across strategic-agreement and non-agreement customers.

Suppliers and costs

Micron operates wafer fabrication, assembly and test facilities, while outsourcing some assembly and other manufacturing processes. Its fabs generally run continuously on 300mm wafers. Manufacturing cost is shaped by process line width, NAND layers and cell levels, process complexity, equipment, yields, material and labor costs, package type, testing, facility utilization and subcontractor use. The company seeks to raise bit density per wafer and reduce cost per bit through new product and process technology.

The company generally has multiple sources for materials and services, but only a limited number of suppliers can meet standards for certain inputs. Some materials, components or services come from a single or sole source. It also depends on outside suppliers of controllers and analog integrated circuits, foundries, assembly and test providers, contract manufacturers, logistics, equipment maintenance and utilities. Long-term supplier contracts do not always secure capacity or pricing.

Materials include chemicals, silicon wafers, gases, photoresists, substrates, printed circuit boards and reticle glass blanks. Supply constraints, AI-driven competition for equipment and packaging, and power, gas or water outages can raise costs or limit shipments.

Competitive position

Micron competes in semiconductor memory and storage with Samsung Electronics Co., Ltd.; SK hynix Inc.; Kioxia Holdings Corporation; Sandisk Corporation; ChangXin Memory Technologies, Inc. and Yangtze Memory Technologies Co., Ltd. Competition covers DRAM, NAND and storage products. Competitors may use aggressive pricing, have greater resources or manufacturing scale, and may operate with lower labor and compliance costs. Government support for competitors and new entrants, including CXMT and YMTC, can add DRAM and NAND supply.

Micron reported a 24.0% DRAM market share in Q2 and an 18.0% HBM market share in Q2. The company seeks to compete through product and process technology, bit density, manufacturing execution, advanced packaging, customer collaboration and its product range. Its 1γ DRAM node was the majority of its DRAM bit production in the fourth quarter of 2026, and its G8 and G9 nodes were the majority of NAND bit production in 2026.

Our reading: Technology-node execution and advanced packaging are meaningful competitive defenses because they influence memory performance, power use, density and manufacturing cost, but competitors are investing in the same markets.

Our reading: Strategic take-or-pay agreements provide visibility into customer demand and supply planning, though they do not eliminate price, technology or capacity competition.

Growth opportunities

Micron is expanding its exposure to AI-related data-center memory and storage, including HBM, server DRAM and data-center SSDs. The company states that cloud servers supporting AI and data-centric workloads require increasing quantities of DRAM and NAND. It also identifies higher memory and storage content in AI PCs, smartphones, autonomous vehicles, robotics and other intelligent-edge systems as growth opportunities.

Data-center SSD revenue was nearly $10.0 billion in fiscal Q4 2026 and represented over two-thirds of company NAND revenue. Management said on the call that it had completed agreements for the vast majority of calendar 2027 HBM bit supply, with significant year-over-year price increases. The company expects its next-generation DRAM and NAND technology nodes to begin volume production in the second half of calendar 2027.

Capacity expansion is a second growth vector. Micron expects first wafer output from its Idaho ID1 fab in mid-calendar 2027, ID2 in late calendar 2028 and its first New York fab in calendar 2030. It also expects initial output from Singapore HBM advanced packaging in early calendar 2027, the Japan DRAM expansion in late calendar 2028 and the Singapore NAND facility in the second half of calendar 2028. The company expects to increase FY2027 capital expenditure versus prior plans, largely to accelerate clean-room availability from late calendar 2028.

Structural risks

• Memory pricing and supply cycles: Average selling prices can vary significantly. If worldwide demand does not grow or remain stable while industry supply rises, prices could decline materially. The company does not have line of sight to when memory supply and demand will return to balance.

• Technology and manufacturing execution: Micron must develop and qualify new products and process nodes, increase bit density and maintain yields. Complexity, defects, equipment issues, underutilization and delayed capacity ramps can raise cost per gigabit and impair output.

• Competitive capacity and pricing: Larger competitors, new entrants and government-backed investment can expand worldwide DRAM and NAND supply. CXMT and YMTC are specifically identified as sources of potential oversupply, and competitors may use aggressive pricing.

• Supply-chain and utility dependence: Limited or sole-source inputs, controllers, foundry and assembly services, logistics, electricity, gas and water can constrain production. Geopolitical tensions, trade restrictions and shortages can delay materials or increase cost.

• Customer and end-market exposure: Revenue depends on certain customers, international customers and demand in end markets. AI-related demand depends on customer investment in hardware and data centers, while some contracts remain short term.

• International regulation: Export controls, tariffs, sanctions, currency movements and other regulations can restrict product sales, technical-information transfers or material availability. China’s CAC decision limiting purchases by critical information infrastructure operators adversely affected the company’s ability to compete in China and elsewhere.

Bottom line

Our reading

Our reading: Micron is a memory and storage manufacturer whose earnings are closely tied to product pricing, shipment volumes, factory utilization and technology transitions. AI-oriented data-center products and strategic customer agreements have increased its exposure to HBM, server memory and SSD demand while providing contracted volume visibility. Its global, capital-intensive manufacturing network and reliance on constrained inputs leave the business exposed to supply disruptions, new industry capacity and memory-price volatility.
