## @SemiconductorsX (Semiconductor Insider) · 09-20 20:31 · ♥54 ↻1 💬7 Big: HBM export unit price dropped for the first time in 5 months.
Korea’s HBM export price just slipped for the first time in five months. That is not the same as demand breaking.
Seoul Shinmun cites Korea International Trade Association data. The average HBM-related export price rose from $40.68 in March to $76.14 in July, up about 87%. In August it fell 3.6% to $73.39.
One reading is more supply. Micron is said to be lifting HBM output from 40,000 to 50,000 wafers a month last year toward about 100,000 by year-end. It started HBM4 in the second quarter.
Samsung is rumored to take year-end capacity from about 170,000 wafers a month toward 250,000. SK Hynix said in June it would double wafer capacity over five years.
The paper is careful. August HBM export value and volume still rose. The basket also includes gear and other items, so one month is not a clean market price.
An industry source said do not treat the print as proof of weaker demand.
On plain DRAM, TrendForce put second-quarter share at Samsung 39.4%, SK Hynix 24.9%, Micron 23.3%, CXMT 9.5%. $MU $SKHY $DRAM The two Korean firms’ combined slice fell from 67.3% in the first quarter to 64.3%.
Reported second-quarter operating margins were CXMT 82%, Micron 80.4%, SK Hynix 76.3%, Samsung DS 70%.
A unit-price dip after an 87% run is a flag, not a crash.
If Micron and CXMT keep adding bits, does HBM stay a scarce premium, or does the next fight become cost on commodity DRAM? https://x.com/SemiconductorsX/status/2101771282669093314
