Samsung Asset Management Cuts Stake from 5.00% to 2.89% — Park Systems

Summary

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.
