Large Shareholding Change Report: Stake Increased to 8.48% via On-Market Purchases — DKEMS

Summary

Park Young Ok, CEO of Smart Income Co., has filed an abbreviated large shareholding report disclosing an increase in his combined stake in The Nature Holdings (KOSDAQ: 298540) from 7.68% to 8.48%, a gain of 115,425 shares (0.80 percentage points). The purchases were made entirely through on-market transactions between late July and early October 2026, with no control-seeking intent — the declared purpose remains simple investment. Park holds 1,169,352 shares directly while his affiliated company Smart Income Co. holds an additional 58,669 shares, for a combined 1,228,021 shares. Smart Income is a securities investment firm of which Park is the 96.8% majority owner and sole decision-maker, making the combined filing effectively a single-party accumulation. The continued steady buying by a known value investor is a modestly positive signal, though the scale is small relative to total shares outstanding.
