Micron Technology has confirmed it has begun shipping its next-generation HBM4 high-bandwidth memory chips, a disclosure that marks a significant step ahead in the AI memory race. The company also broke ground on a $9.3 billion manufacturing facility in Japan designed to scale production of AI-focused memory products. This follows a strong Q3 earnings beat and forward guidance that exceeded expectations, though the stock remains roughly 23% below its 52-week high of $1,255.
HBM4 is the memory standard that next-generation AI accelerators will depend on, meaning Micron is positioning itself directly in the spending path of hyperscalers building out AI infrastructure. The Japan plant signals a multi-year capacity commitment that could tighten supply and support pricing power. Investors in AI infrastructure plays — from chip stocks to data center ETFs — should watch Micron as a leading indicator of where AI hardware demand is heading.
Micron's next quarterly earnings report (Q4 fiscal year results, typically late June to late September window). Watch for any NVIDIA or AMD product launch announcements that specify HBM4 compatibility, as those would confirm customer pull-through.
