Summary

CEO and de facto controlling shareholder Park Young Jun acquired an additional 10,000 common shares through open-market purchases on May 28 and June 1, 2026, lifting his holdings from 3,268,470 to 3,278,470 shares (22.56% → 22.63%). The purchases were made at 6,600 won (1,000 shares) and 6,369 won (9,000 shares) per share, totaling roughly 64 million won.

The transaction size is small relative to total shares outstanding (14,486,386), so the direct ownership impact is marginal.
