Notes
Global leader in industrial AFM with dominant share in semiconductor-grade AFM systems, benefiting from rising demand for advanced-node metrology (EUV, HBM, advanced packaging). Expanding into in-line process AFM as nodes shrink below 3nm, where traditional CD-SEM struggles. Key risk is concentration in capex-sensitive memory customers and competition from optical/e-beam metrology alternatives from KLA and Applied Materials.
Samsung Asset Management filed an abbreviated large-holding report disclosing that its stake decreased from 350,152 shares (5.00%) to 201,905 shares (2.89%), a reduction of 148,247 shares (-2.11 percentage points) as of May 12, 2026. The change was triggered by trading activity, with the holding purpose declared as simple investment (no management participation intent). The reported position includes 530 shares (0.01%) entrusted to Samsung Active Asset Management. Detailed transaction records show a mix of on-market purchases and ETF setup/redemption-related movements at prices around KRW 258,000–271,125. Because the stake fell below the 5% threshold, this is the institutional shareholder's final mandatory disclosure unless its holding rises back above the reporting trigger.
