Industry Analysis
Micron’s surge reflects AI clusters’ insatiable demand for high-bandwidth DRAM, reshaping the entire hardware stack—from HBM3e packaging to TSMC’s (Taiwan, China) CoWoS bottlenecks, inflating server BOM costs. U.S. export controls, while partially exempting memory chips, have already raised Micron’s China compliance costs by over 12%, forcing costly supply chain redundancies. With Samsung and SK Hynix racing toward HBM4, Micron risks losing its narrow tech window unless it secures advanced packaging capacity like CoWoS or Foveros before 2027. The next 18 months may see an artificially extended memory upcycle, but once large-model training plateaus, inventory corrections could be sharper than historical norms. Current valuation fully prices in 2027 earnings—trading congestion now borders on hazardous.
