Micron HBM4 volume shipments to NVIDIA Vera Rubin verified as material to earnings
Key Questions
What is the significance of Micron's HBM4 shipments?
Q2'26 confirmed HBM4 36/48GB mass production starting mid-March drove earnings beats. Shipments to NVIDIA Vera Rubin are verified as material to earnings, with volumes sold out through 2026.
What are Micron's HBM4 supply and contract details?
Micron has 5-year contracts and LOIs, with expansions to 15k wafers/month in 2027. Supply remains tight through 2026 due to delayed output, reinforced by hyperscaler AI capex tailwinds.
What expansions is Micron undertaking for HBM?
Micron plans a $9.6B Hiroshima fab for 2027-28 operations. This supports sold-out HBM4 demand and AI-driven surges.
How does SK Hynix compare in the HBM market?
SK Hynix leads in capex to retake HBM dominance from Samsung and Micron, ramping spending and EUV expansion. This heightens competition amid GPU rental shortages up 40%.
Why is HBM demand locked up?
AI-driven demand has memory suppliers booked out two years, with DRAM prices surging 90-95%. Hyperscalers' 30% AI capex provides tailwinds.
What recent stock movement occurred for Micron related to HBM?
Micron stock rose 3.95% on April 6, driven by AI-memory pricing momentum and HBM4 ramp keeping sentiment strong. Shares also jumped 3.1% on bullish KeyBanc notes.
How is Micron advancing AI memory beyond HBM?
Micron is reportedly developing stacked GDDR to address shifting AI memory demand. Partnerships like with Applied Materials deepen R&D for next-gen tech.
What does the 'Father of HBM' predict for AI architecture?
The 'Father of HBM' predicts memory will replace GPUs as the core in AI architecture, disrupting current designs amid ongoing HBM demand lockup.
