Mirae Asset Becomes 5%+ Major Shareholder with 9.92% Stake — DB HiTek

Summary

Mirae Asset Global Investments has filed an initial major shareholder disclosure for DB HiTek, reporting ownership of 4,316,405 shares (9.92%) as of May 8, 2026. This is a new filing triggered on May 4, 2026, indicating the asset manager has crossed the 5% reporting threshold and now holds just under 10% of outstanding shares. The bulk of the position (4,246,641 shares) was pre-existing holdings, with subsequent daily changes driven primarily by ETF creation/redemption activity, securities lending, and modest on-market trades. Transaction prices ranged from roughly KRW 152,600 to KRW 162,000 over the May 4-8 reporting window. The disclosure signals that a major domestic institutional investor holds a substantial position in DB HiTek, though much of the activity reflects passive ETF mechanics rather than active conviction trades.
