Micron Technology reported full-year FY2025 revenue of $37.4B, a 48.9% YoY increase, with gross margins of 39.8% and diluted EPS of $7.59 — a dramatic improvement from the trough of the memory downcycle. The headline figure of 346% likely refers to the HBM3E segment or a specific quarterly revenue comparison that underscores how sharply AI-driven demand has inflated memory unit economics.

Micron is the primary pure-play on HBM (high-bandwidth memory), which sits inside every major AI accelerator including NVIDIA's H100 and B200. This positions MU as a structural beneficiary of hyperscaler capex expansion, alongside names like Samsung and SK Hynix on the supply side.

The bull tension here is whether the HBM cycle has legs deep into 2026 or whether the current surge pulls forward demand, creating a hangover. Memory is notoriously cyclical: DRAM pricing can reverse sharply on supply expansion, and Micron is aggressively ramping capacity. Net margin of 22.8% is healthy but not yet peak-cycle territory, suggesting room to run if pricing holds.

What to watch: HBM allocation announcements, any signs of pricing softness in commodity DRAM, and capex guidance updates from hyperscalers (MSFT, GOOGL, META, AMZN). A deceleration in AI server orders would reprice MU faster than almost any other chip name given its memory-price sensitivity.
