Micron Technology, Inc.
Micron Technology, Inc. designs, develops, manufactures, and sells memory and storage products in the United States, Taiwan, Japan, Mainland China, Hong Kong, Europe, and internationally. It operates through the Cloud Memory Business Unit; Core Data Center Business Unit; Mobile and Client Business Unit; and Automotive and Embedded Business Unit segments. The company provides memory products, including dynamic random access memory components and modules, CXL-based memory, LPDDR components and modules, graphics memory, high-bandwidth memory, and data center memory products; multichip packages (MCP) comprising embedded multimedia card-based, universal flash storage-based, and NAND-based MCPs; and technology leadership products that include 1y DRAM and G9 NAND technologies. It also offers storage products, such as data center solid-state drives (SSD), client SSD storage, and auto and industrial SSD storage; managed NAND; NAND flash; NOR flash; and memory cards. In addition, the company provides design tools, including FBGA and part decoders; DRAM power calculators; NAND power calculators; simulation models; chipset compatibility guides; serial presence-detection tools; cross-reference tools; UFSparm; SSD firmware; software and drivers; storage executive software; and obsolete part catalogs. It markets its semiconductor memory and storage products under the Micron and Crucial brands. The company serves the data center, PC, graphics, networking, automotive, industrial, and consumer embedded markets, as well as the smartphone and other mobile-device markets. It sells its products through its direct sales force, independent sales representatives, distributors, and retailers; web-based customer direct sales channel; and channel and distribution partners. Micron Technology, Inc. was founded in 1978 and is headquartered in Boise, Idaho.
What does it do?
Micron makes the memory chips that sit inside almost every piece of modern technology — your phone, laptop, data center server, and even your car. There are two main types: DRAM, which acts like a device's short-term memory (letting it run multiple apps at once), and NAND flash, which is long-term storage (like the chip version of a hard drive). When you open an app instantly or stream a video without lag, memory chips like Micron's are doing the heavy lifting behind the scenes. Micron is one of only three companies in the world that can make these chips at scale — the others are Samsung and SK Hynix, both based in South Korea.
The explosion in AI has made memory chips more critical than ever — AI models require enormous amounts of fast memory to process data, and a new type of chip Micron makes called HBM (High Bandwidth Memory) sits directly alongside AI processors like Nvidia's GPUs to feed them data at extreme speeds. Micron's revenue jumped from $25.1B to $37.4B in a single year, a 49% increase, almost entirely driven by this AI-fueled demand surge. With only three companies on Earth able to supply this technology, Micron sits at a chokepoint in the global AI supply chain.
How does it make money?
Micron sells memory and storage products to four main customer groups: cloud companies like Amazon, Google, and Microsoft (its largest and fastest-growing segment); data centers broadly; smartphone and PC makers; and automotive and industrial clients. Its $37.4B in annual revenue comes almost entirely from selling DRAM and NAND chips, with DRAM — especially the premium HBM variety used in AI servers — now the dominant profit driver. The company turned $8.5B in net profit on that revenue, meaning it kept roughly 23 cents of profit for every dollar earned, a dramatic turnaround from the prior year when the memory market was in a deep slump.
Why do investors care?
The core investment story is simple: AI needs memory, and Micron is one of three companies that can supply it. HBM chips — the premium memory used in AI accelerators — sell for many times the price of standard chips, and Micron is ramping up HBM production aggressively to compete with Samsung and SK Hynix. For the thesis to work, AI infrastructure spending by big tech companies needs to keep rising, and Micron needs to win a larger share of HBM orders from customers like Nvidia. The wildcard upside is that memory has historically been a boom-bust industry, and if this AI cycle proves longer and more stable than past cycles, Micron's earnings could consistently beat expectations for years.
