Haghighi Farshad 4

What Happened
Farshad Haghighi, Executive Vice President of Amkor Technology (AMKR), had 1,789 restricted stock units (RSUs convert to common shares) vest and converted those RSUs into 1,789 shares on Feb 16, 2026. To satisfy tax-withholding obligations, 816 of those shares were withheld at $47.48 each (total value withheld $38,744). Net shares retained by the reporting person after withholding were 973 shares (approx. $46.2k based on $47.48 per share). This was not an open-market sale but a routine tax withholding on vesting.

Context
This is a routine RSU vesting and tax-withholding transaction (derivative conversion followed by withholding), not an open-market sale or a separate cash purchase. Such transactions are common when equity awards vest and don’t by themselves indicate a buy/sell sentiment.
