Micron's FY2025 revenue of $37.4B represents a 49% YoY surge, with gross margins expanding to 39.8% and diluted EPS of $7.59 — numbers that reflect HBM's emergence as a structurally higher-ASP product category versus commodity DRAM. The AI training and inference buildout, led by hyperscalers and GPU platforms, has pulled forward HBM3E demand faster than supply can scale, giving Micron pricing power it hasn't historically enjoyed.

The second-order question is duration: memory markets are historically cyclical, and if AI capex slows or Samsung/SK Hynix catch up on HBM supply, pricing could compress sharply and MU's margins could revert. Investors should watch HBM allocation commentary in the next earnings call, any signal of customer inventory builds, and competitor capacity announcements as the key forward indicators.
