Engel Kevin K. 4

What Happened

• Kevin K. Engel, President, CEO and Director of Amkor Technology (AMKR), reported RSU vesting and subsequent share sales. On Feb 16, 2026, 1,345 RSU shares converted to common stock (derivative conversion). The company withheld 559 shares to cover tax withholding (valued at $47.48 each, $26,541). On Feb 17, 2026, Engel sold 5,316 shares in an open-market transaction at $46.03 each for $244,695.
• This sequence (RSU vest → shares withheld for taxes → open-market sale) is a routine insider sale tied to equity award vesting rather than a fresh purchase — typically not a bullish signal.

Context

• This was an RSU vesting event (derivative conversion) with a routine tax-withholding share retention and an open-market sale of vested shares. That pattern is common when executives realize proceeds from vested equity; it documents monetization of compensation rather than a directional investment bet.
