KIM SUSAN Y 4

What Happened

• Susan Y. Kim, a reported 10% owner of Amkor Technology (AMKR), exercised stock options on April 7, 2026. She acquired 20,000 shares at $5.66 per share for a cash outlay of $113,200 (reported as an "Acquired" M-code transaction). The filing also reports a related "Disposed" M-code entry for 20,000 derivative units at $0.00 (no cash proceeds), reflecting conversion/settlement of derivative securities associated with the option exercise.
• This transaction is an option exercise (M code). It represents a purchase of common stock via exercise rather than an open‑market sale; it does not show that shares were sold on the market.

Context

• M-code transactions = exercise/conversion of derivatives (options). The pair of entries (one acquired at $5.66, one disposed at $0.00) commonly reflects settlement mechanics of an option exercise (e.g., conversion/surrender of option rights), not an open‑market sale of acquired shares.
• As a reported 10% owner with holdings held through trusts and partnerships, Ms. Kim’s trading is institutional/beneficial-interest reporting rather than routine executive trading. These kinds of filings document changes in economic interest but do not by themselves indicate company outlook.
