Notes
Tese is a leading Korean test consumables maker, historically focused on memory probe cards for SK Hynix and Samsung, and has been expanding into DRAM/HBM probe cards and test sockets to capture growing AI memory test demand. The company also has an OSAT-style packaging/test services arm via subsidiaries, diversifying revenue beyond consumables.
CEO Kim Chul Ho filed an amended major shareholding report following an on-market sale by a related party, with the reporting group's combined stake decreasing by 706 shares to 3,219,696 shares. Despite the share count reduction, the ownership ratio remains unchanged at 29.11% of the 11,061,429 voting shares outstanding. The number of related parties declined from 10 to 9, suggesting one related party exited the reporting group entirely. The stated purpose remains influence over management control, consistent with Kim's role as CEO. The transaction is immaterial in size and unlikely to signal any meaningful shift in insider sentiment or control structure.
