KLA is trading at $175.66 (-3.96%) after investors focused on optical-component supply constraints and rising memory costs disclosed at the September 9 Citi conference.
- Memory costs represent an approximately 100-basis-point gross-margin headwind.
- Optical shortages may limit near-term shipments.
- The broader semiconductor sector is also under pressure, but company-specific profitability concerns appear to be the sharper catalyst.
