Micron Earnings Have Never Looked Better. Start Worrying. - Trefis

Micron Technology has seen an extraordinary stock performance, with its share price rising nearly ninefold over the past year and market capitalization surpassing $1.2 trillion—marking the largest sin... Read original →

Micron’s valuation surge stems from HBM3e’s tight integration with AI accelerators, yet this boom is destabilizing memory’s cyclical equilibrium. Upstream EUV and 3nm advanced packaging bottlenecks are forcing GPU makers into long-term contracts, masking inherent volatility. Samsung and SK Hynix are fast-tracking HBM4 while leveraging U.S.-Japan-Korea supply chain realignments to gain customer trust—despite higher compliance costs. Crucially, if AI capex growth decelerates in late 2026 as model ROI plateaus, Micron’s 9.6x forward P/E will quickly unravel. History shows memory markets never escape cyclicality, regardless of 'structural demand.' With $75B+ annual capacity investments set to flood the market by 2027, a price war looms. The real long-tail advantage lies not in HBM volume, but in fusing AI memory with near-memory or in-memory compute architectures—otherwise, today’s euphoria becomes tomorrow’s inventory crisis.
