Micron's Sept 30 print tests memory sold out into 2028 while HBM price growth decelerates
Micron reports September 30 with HBM4 ramping about twice as fast as HBM3E, 86% gross margins, roughly $100bn of customer agreements and tightness guided beyond CY2027, while Samsung is set for its first 100tn-won quarter. The debate is the slope: TrendForce shows Q3 memory price gains slowing to low double digits from about 60% in Q2, and BofA expects 2027 HBM ASP growth far below 100%. Consensus is high.
