Micron's AI-Driven Memory Expansion

Micron is investing $10B in a Boise research lab and $50B overall to meet surging AI memory demand. Record revenues, 84.6% gross margins, and strong analyst upgrades (BMO $1,300, New Street $1,250) contrast with a recent stock pullback and Bridgewater's stake reduction. The narrative is shifting from cyclical to structural growth, with customers demanding 50% more supply than available. However, new analysis highlights risks: net margin at 56% vs 7.5% average signals potential mean reversion, revenue growth is price-driven not volume, and NAND share is being lost to YMTC. Take-or-pay agreements cover only a fraction of volume, challenging the structural shift thesis. Key risks: macro headwinds and memory cyclicality.
