Samsung Asset Management Reduces Stake Below 6% Threshold
Samsung Asset Management filed an abbreviated large-shareholding report disclosing that its stake fell from 7.16% to 5.92% as of June 1, 2026, a decrease of 610,707 shares (-1.24 percentage points). The reduction was driven by simple buying and selling activity during March 2026, including on-market sales and ETF-related adjustments, with the holdings classified as simple investment (no management influence intent). The reported figure includes 1,581 shares delegated to Samsung Active Asset Management. With the stake now near the 5% disclosure threshold, further selling could trigger an exit from mandatory reporting, signaling continued institutional outflow.

Notes

Wonik IPS is Korea's largest domestic semiconductor equipment maker, supplying CVD/ALD/etch tools mainly to Samsung Electronics (its dominant customer) and SK Hynix. The company benefits from Korean fabs' localization push but remains heavily exposed to Samsung memory capex cycles, and it faces strong competition from larger global incumbents like Applied Materials and Tokyo Electron.

Major Shareholding Report: Stake Edges Down to 32.95% on Insider Sales & Pledge Extension

Wonik Holdings, the largest shareholder, reported a minor reduction in its combined holding from 32.98% to 32.95% (-18,411 shares) as of May 15, 2026. The change reflects on-market sales by special-related parties and the departure of one executive (reducing the special-related party count from 5 to 4). Wonik Holdings also extended and modified terms on an existing share-pledged loan agreement covering 7,850,000 shares (15.99%), unchanged in size. The holding purpose remains 'influence over management,' though no specific control-related actions are currently planned. Total issued shares remain 49,083,901.

Q1 2026 Preliminary Consolidated Earnings: Revenue +32.8% YoY, Returns to Profit

Wonik IPS reported preliminary Q1 2026 consolidated revenue of KRW 164.9 billion, up 32.8% year-over-year but down 40.0% quarter-over-quarter from a strong Q4 2025. Operating profit came in at KRW 10.7 billion, a swing to profit from a KRW 7.4 billion operating loss in Q1 2025, though down 37.6% sequentially. Net income reached KRW 22.1 billion, also a turnaround from a KRW 4.7 billion loss a year earlier. The strong YoY recovery signals improving demand in the semiconductor equipment cycle, while the sequential decline reflects normal seasonality after a peak Q4. Figures are preliminary K-IFRS consolidated results and unaudited.
