Executive Stock Holdings Report: Director Exercises Options After Selling Same Quantity — Hana Micron

Summary

A non-registered executive (Managing Director Kim Jin-seok) reported a two-step transaction that left his total holdings unchanged at 5,200 shares (0.01%). On May 26, 2026, he sold all 5,200 shares on the open market at KRW 57,000 per share, then on June 2, 2026, he exercised stock options to acquire 5,200 new shares at an exercise price of KRW 8,065. The net economic gain from the spread (roughly KRW 48,935 per share, or ~KRW 254 million total) suggests an option-cashout strategy rather than a directional view on the stock. Net ownership change is zero, limiting signaling impact, though the open-market sale could be read as mildly negative sentiment by retail investors.
