Amendment to Executive/Major Shareholder Securities Ownership Report — Samsung Electronics

Summary

An amendment was filed to correct the detailed transaction history in an executive's securities ownership report. The reporter, Kim Kyoung-seok, a non-registered executive (Managing Director, Foundry FAB3 Team), holds 237 common shares as of May 29, 2026, representing essentially 0.00% of total shares outstanding. The correction involves restating intraday buy/sell transactions on May 29, 2026 at prices around KRW 320,500-321,000, with a net change of just 1 share from the previous report. Given the negligible share count (237 shares) relative to the 6.6 billion shares outstanding, this filing carries no material implication for the stock.
