Micron Technology, Inc.

Micron Technology, Inc. designs and manufactures DRAM, NAND and NOR memory and storage products — the components that hold working data in every AI accelerator, server, smartphone and car — and sells them under the Micron and Crucial brands into cloud, data-center, mobile and client, automotive and embedded markets. It is one of only a handful of companies that still make memory at scale, the only large one headquartered in the United States, and it operates front-end wafer fabs in Taiwan, Japan, Singapore and the United States with back-end assembly and test in Malaysia, China and India.

This is a story about a commodity producer trying to convince the market it has stopped being one. In the nine months to 28 May 2026 Micron earned $47.3 billion of net income — five and a half times what it earned in the whole of the prior fiscal year, and more than the entire shareholders' equity it carried into fiscal 2025 — and in the most recent quarter alone revenue grew 346% year over year to $41.5 billion on an 85% gross margin. The company argues the change is structural: that AI has recast memory from a component into a strategic asset, and that a set of multi-year, take-or-pay customer contracts with price floors will hold margins above anything the industry has achieved before. Investors have largely accepted the argument. The shares closed at $975.56 on 2 July 2026, giving the equity a market value of about $1.10 trillion, up roughly nine-fold from the low of the trailing year.

The file turns on one question: whether those contracts and the demand behind them represent a genuine regime change in memory economics, or the most elaborate costume a cyclical peak has ever worn. Almost everything else follows from it — the margin debate, the capital-allocation debate, and what a trillion-dollar valuation for a company that lost $5.8 billion three years ago actually implies.
