Largest Shareholder Group Share Holdings Change Report — Samsung Electronics

Summary

Samsung Life Insurance's special account reported a net decrease of 32,729 shares in its Samsung Electronics holdings between May 8 and June 8, 2026, comprising a 40,179-share reduction in common stock partially offset by a 7,450-share increase in preferred stock. The activity reflects routine in-market trading by the special account rather than a strategic stake change, with the largest shareholder group's combined ownership ratio unchanged at 17.33%. Samsung Life's principal account still holds 8.51% of common shares, with affiliates Samsung C&T (5.11%) and Samsung Fire & Marine (1.49%) rounding out the major insider holdings. This is a standard monthly regulatory filing capturing routine portfolio rebalancing within an insurer's special account, not a directional signal on the stock.
