Amended Insider Holdings Report — Corrected Share Count for Executive — Samsung Electronics

Summary

This is an amendment to a previously filed insider ownership report for non-registered executive Henrik Johan Jansson (Strategic Marketing Team VP). The original report incorrectly stated his holdings as 2,443 shares (prior) and 3,046 shares (current); the correct figures are 337 shares and 937 shares respectively. The underlying transaction — an on-market purchase of 600 common shares at 168,000 KRW on April 2, 2026 — remains unchanged. This is purely a clerical correction with no change to the actual trade or economic substance, and the total holding remains negligible at 0.00% of outstanding shares.
