Haghighi Farshad 4

What Happened
Farshad Haghighi, Executive Vice President of Amkor Technology (AMKR), had performance-vested restricted stock units (PSUs) vest on Feb 18, 2026 (7,597 shares total) and received a new grant of 18,185 time‑vested restricted stock units (RSUs). To cover tax withholding on the vested PSUs, the issuer withheld 3,659 shares (disposed) at an attributed price of $46.74 per share, totaling about $171,022 (two withholdings: 1,038 shares = $48,516; 2,621 shares = $122,506). The RSUs were awarded for service and will vest in three equal annual installments beginning on the first anniversary of the Feb 18, 2026 grant date.

Context
These were award/vesting and withholding transactions (codes A and F). The PSUs vested based on a company performance metric (basic EPS), and the withheld shares were used to meet tax obligations — a routine administrative step, not an open‑market sale. New RSUs are time‑vested equity compensation that vests over three years. Such grant/withholding filings are common for executives and do not by themselves indicate a buy/sell signal.
