Largest Shareholder Stake Drops to 25.03% as Special-Relation Parties Removed — DB HiTek

Summary

The largest shareholder group's combined holding decreased by 1,532,260 shares (-3.51%p), falling from 28.55% to 25.03% as of May 19, 2026. The reduction was not driven by share sales but by the dissolution of the special-relationship status of four affiliated parties — Biltech Co., Samdong Heungsan Co., and two affiliate executives (Kim Jae-young, Shin Hae-cheol) — following the suspension of their deemed-inclusion effect. DB Inc. remains the principal shareholder with 19.75% (8,613,783 shares), and no actual disposal of shares by the controlling family occurred. The change is technical/regulatory in nature rather than reflecting a shift in control or insider sentiment.
