Micron Posted an 84% Gross Margin on Memory. That's the Re-Rate.

The Number That Re-Rated the Stock

Micron's fiscal third quarter was always going to be big — the only question was how big. The answer: $41.46 billion in revenue, up 346% year over year and 74% sequentially, with non-GAAP EPS of $25.11 against roughly $20.63 expected. But the figure that moved the stock isn't on the top line. It's the gross margin of 84.6%. A DRAM and NAND maker — the textbook commodity cyclical, the business that spent decades whipsawing between glut and shortage — just printed a margin that looks like enterprise software. That single number is the entire re-rate, and it's why $MU is trading around $1,236 instead of digesting a good-but-priced-in beat.

How a Memory Maker Prints 85%

Margins like this don't come from selling more chips at last year's price; they come from selling chips the buyer can't source anywhere else. Micron said HBM is sold out through 2026, with HBM4 already in high-volume production for its lead customer and qualification samples out to others. Stack that on the multi-year, fixed-price supply agreements Micron has been signing with hyperscalers — the structure that strips the downside out of the memory cycle — and you get pricing power this industry historically never had. The floors are why the margin holds through a downturn; the sold-out HBM book is why it's this high right now. The bet embedded in a $1,236 share is that neither of those unwinds before 2027.

The Street Is Still Repricing

The analyst reaction tells you how badly the sell side was positioned. KeyBanc lifted its target from $600 to $1,600 in a single note — not a revision, a capitulation — while Susquehanna went to $2,000, Needham to $1,650, and Bank of America to $1,550. Management then guided Q4 to $50 billion in revenue at roughly 86% gross margin, well above the ~$43 billion consensus. When a forward guide lands 16% over the Street and a desk has to nearly triple its price target overnight, the move isn't a reaction to the quarter — it's a reaction to a model that was built for the wrong company. The perp catching $872M in 24h HIP-3 volume is the same repricing playing out with leverage.
