Industry Analysis
Micron’s June 24 earnings hinge not on revenue but on delivering its guided 81% gross margin—a litmus test for sustained pricing power in AI-driven DRAM and HBM. Technically, HBM3E/4’s reliance on TSV and advanced packaging ties Micron to TSMC’s CoWoS capacity, where it lags Samsung in ecosystem control. Geopolitically, while U.S. CHIPS Act subsidies ease capex burdens, escalating U.S.-China tech restrictions threaten its mainland China back-end operations, inflating compliance costs. With Samsung and SK Hynix aggressively scaling HBM4, any margin miss could ignite a price war reminiscent of 2019’s memory crash. Even if AI demand holds, the next 12–24 months risk a supply glut that collapses profitability—exposing Micron’s trillion-dollar valuation as built on transient supply-demand imbalances.
