Earnings Call Highlights:
Guiding 2025 DRAM bit demand growth mid-to-high teens% (raised); NAND bit demand growth low-teens% (unchanged); Guiding mid-term DRAM/NAND bit demand CAGR mid-teens%;
Guiding DRAM front-end cost including HBM flat in FY25 (reduced); NAND front-end cost down low-teens% (unchanged);
HBM3E consumes 3x wafers vs. D5; HBM4 will consume more; HBM4E will consume >4x wafers;
Guiding FQ3 capex >$3B; FY25 capex $14B (unchanged), mostly HBM-related; Guiding gross margin to improve in FQ4;
DIO 158 days this quarter, up 9 days sequentially; Guiding DIO to gradually decline, below 120 days by FY25Q4;
Guiding FY25 full-year LP4 and DDR4 related global revenue exposure ~10%;

Overall, Micron's earnings were mediocre, mainly due to weak consumer electronics and auto, plus near-term data center SSD oversupply concerns.
This quarter Micron again lifted its 2025 HBM TAM by $5B to $35B; at a 20% share target that implies $7B, another roughly $1B increase, though it may be offset by weakness in other businesses.
Micron currently trades at 2.2x P/B, one standard deviation above its historical valuation range, while global HBM leader SK hynix is at 2.1x P/B (24Q4) and laggard Samsung Electronics at 0.96x P/B (24Q4).
