Samsung, SK hynix Set to Post Record Q3 Operating Profit - Businesskorea

The record-breaking Q3 earnings of Samsung Electronics and SK hynix underscore a structural shift in the global memory semiconductor market driven by unprecedented AI data center demand. Rather than a... Read original →

This super-cycle is not a demand pulse but a structural supply lock. HBM4 advanced packaging is cannibalizing wafer capacity, creating a hidden shortage: DDR5 lead times have ballooned from six weeks to 52, as AI chips displace legacy server and consumer workloads. Technically, HBM4's expansion into Broadcom and Marvell ASIC ecosystems dilutes NVIDIA's single-customer dependency, yet hybrid bonding's yield threshold for 12+ layer stacks means meaningful capacity additions won't materialize before late 2026. On risk, advanced packaging remains heavily concentrated in Taiwan, China's CoWoS capacity—a single-point-of-failure for Korean memory giants. Any further tightening of U.S. IP export controls on HBM4 would directly impair Samsung and SK hynix's overseas delivery. Competitively, Samsung's 815% profit surge confirms a seller's market, but the real inflection point is 2027. When Samsung's HBM4E yield crosses 85% and Intel's Gaudi4 ramps, the question becomes who fills the supply gap first. My call: through Q4 2027, pricing power stays firmly with the Korean duopoly. By 2028, as ASIC customers mature in-house HBM packaging, premium margins will compress by over 30%.
