Industry Analysis
Micron’s surge stems from AI’s insatiable demand for HBM, colliding with constrained advanced-node capacity. Its tight co-design loop with NVIDIA’s CoWoS has set a de facto standard, pressuring SK Hynix and Samsung to accelerate 3nm EUV-based HBM3E yield ramps—though equipment lead times and material shortages delay scaling. U.S. export controls shield Micron’s China exposure short-term but inflate compliance costs and cloud customer visibility. Strategically, Samsung may exploit any memory price dip to launch counter-cyclical capex, echoing its 2017 DRAM offensive. Over the next 12–24 months, slower AI cluster deployment or breakthroughs in CPO (co-packaged optics) that reduce HBM reliance could trigger a valuation reset. The memory industry hasn’t escaped cyclicality—it’s merely stretched the cycle’s wavelength.
