Micron Stock Crashes 13% on SemiAnalysis Report, Despite Nvidia HBM4 Certification Approval on June 5

According to a SemiAnalysis report released on Friday (June 5), Micron Technologies stock plummeted 13% to $864.01, marking its largest single-day drop since April 2025. However, on the same day, Nvidia CEO Jensen Huang announced that Micron had been approved as an HBM4 qualified supplier alongside SK Hynix and Samsung, a significant endorsement that typically would be bullish news. The contradiction sent mixed signals to the market, with the stock facing continued selling pressure despite the positive development.

SemiAnalysis' report claimed that Nvidia had reduced module memory capacity (SOCAMM DRAM) for its next-generation Vera Rubin server from 55TB to 28TB, a move the market interpreted as cooling AI memory demand. However, industry analysts clarified that SOCAMM is a different product category from high-bandwidth memory (HBM), which actually powers AI server demand. Micron's CFO subsequently countered inaccurate reporting, confirming that HBM4 had entered mass production with shipment paces ahead of schedule, and formally announced HBM4 36GB 12H production for Nvidia's Vera Rubin with bandwidth exceeding 2.8 TB/s.
