Executive Yoon Jang-Hyun Buys 1,890 Shares, Raising Stake to 3,190 — Samsung Electronics

Summary

President Yoon Jang-Hyun, a non-registered executive, purchased 1,890 common shares on the open market on June 4, 2026 at ₩332,000 per share, increasing his total holdings from 1,300 to 3,190 shares. The total transaction value is approximately ₩627 million. While the stake remains effectively 0.00% of the 6.65 billion outstanding shares, insider buying by a sitting president can be read as a mild signal of management confidence.
