onsemi and Semtech Shares Are Falling, What You Need To Know - FinancialContent

The semiconductor sector experienced a notable correction amid a sharp downturn in South Korean chip stocks, renewed concerns over debt-financed AI capital spending, and a hawkish repricing of Fed rat... Read original →

SK Hynix’s reallocation from HBM to mainstream DRAM isn’t a demand collapse but a margin-driven retreat amid soaring EUV costs and sub-3nm packaging yield constraints. This shift disrupts the HBM ecosystem—especially TSV and advanced substrate suppliers—while benefiting logic-focused players like onsemi and Semtech, whose automotive SiC and analog chips are insulated from AI capex volatility. Geopolitically, tightening U.S. export controls compel Korean foundries to accelerate U.S. fab builds, inflating Capex and squeezing near-term margins. Samsung and Micron may seize HBM3E share as ASML’s High-NA EUV delays widen the technology gap. Over the next 18 months, expect consolidation: low-margin AI accelerator vendors will exit, while vertically integrated IDMs solidify dominance in automotive and industrial segments.
