Micron Technology, Inc.

Micron Technology, Inc. is an American semiconductor company that designs, manufactures, and sells memory and storage products — primarily DRAM, NAND flash, and high-bandwidth memory — to customers across data center, mobile, PC, automotive, and industrial markets, generating $37.4 billion in revenue in fiscal 2025. As the only U.S.-based manufacturer of advanced DRAM, and one of only three global players at the leading edge alongside Samsung and SK hynix, Micron occupies a structurally scarce position in the semiconductor supply chain at a moment when memory has been recast from a commodity input into a strategic enabler of artificial intelligence.

This is a story about cyclicality meeting a secular demand shock. Micron has spent four decades navigating the memory industry's violent boom-bust cycles — losing over $5 billion in FY2023, then earning $8.5 billion in FY2025, and now running at an annualized net income approaching $50 billion based on its most recent quarter. The difference this time is that AI workloads are generating demand for memory that the industry's wafer fabrication capacity cannot satisfy, creating a supply-demand imbalance that management expects to persist beyond 2026. The file turns on a single question: whether the structural drivers of AI memory demand can keep the cycle elevated long enough for Micron to build a permanently more valuable business — or whether the old rhythm of overbuild and price collapse reasserts itself before the company's $25 billion-plus annual capital expenditure program generates a return.

The tension is live. Micron's stock has tripled in the past year to a market capitalization above $1 trillion, and the guided FQ3 2026 gross margin of 81% exceeds anything in the company's history. The numbers are breathtaking but so is the embedded expectation. What follows is an attempt to understand the business underneath the cycle.
