Why Is Micron Stock Falling Despite Solid Results?

Key Points:

• Micron reported a record fiscal Q3 2026 with revenue of $41.46 billion, adjusted EPS of $25.11, and a gross margin of 84.9%, surpassing expectations and guiding fiscal Q4 revenue $6.5 billion above estimates, yet its stock fell over 20% from post-earnings highs amid a broad memory sector selloff.
• Despite strong earnings, investors remain cautious due to concerns about the sustainability of Micron's peak margins and pricing power, especially given the cyclical nature of the memory industry and the risk of increased supply.
• Major competitors Samsung and SK Hynix are heavily investing in capacity expansion, with combined capital expenditures around $130 billion in 2026 and plans for massive semiconductor clusters, which could increase supply and pressure prices.
• Customers like Apple have raised product prices due to rising memory costs, and some companies are imposing limits on AI-related spending, signaling potential constraints on demand growth for memory used in AI infrastructure.
• SK Hynix’s upcoming Nasdaq listing provides U.S. investors a new pure-play memory stock option, potentially prompting portfolio shifts away from Micron, while Apple’s negotiations to source memory from China’s CXMT suggest quicker resolution of memory shortages than previously expected.
