Notes
Korea Circuit is part of the Younghwa Group and is one of Korea's major PCB and semiconductor package substrate makers, with ongoing investment in FC-BGA capacity to serve growing demand from memory and SoC packaging. The substrate segment faces cyclical exposure to memory and smartphone demand, and competes against larger Japanese incumbents (Ibiden, Shinko) in high-end FC-BGA.
Mirae Asset Global Investments filed a new 5% bulk shareholding disclosure after its combined holdings (including two affiliated funds) rose to 1,256,367 shares, or 5.24% of outstanding shares, up from 4.96% (1,188,811 shares) one day earlier — an increase of 67,556 shares (+0.28%p). The acquisition was made on-market by the asset manager's internal investment decisions, including ETF creation/redemption activity. The reported purpose is simple investment (passive), not control. Of the reporter's own 1,230,563 shares, 379,143 (1.58%) are held under discretionary investment management contracts. As a passive 5% crossing by an institutional asset manager, this is a disclosure trigger rather than a strategic signal.
