Amkor (AMKR) CEO Kevin Engel Converts RSUs; Shares Withheld for Taxes
What Happened
- Kevin K. Engel, President, CEO and Director of Amkor Technology (AMKR), had time‑vested restricted stock units (RSUs) convert into 16,853 shares on Feb 20, 2026 (reported on Feb 24). The company withheld 6,883 of those shares to satisfy tax withholding at $47.94/share (total withheld value reported as $124,500 and $205,471, combined ~$329,971).

These transactions are conversions of RSUs (transaction code M) with withholding for tax liabilities (code F), not open‑market sales.
Key Details
- Transaction date: February 20, 2026; Filing date: February 24, 2026 (filed within the required reporting window).
- Prices/values: tax withholding executed at $47.94 per share; withheld shares valued at $124,500 and $205,471 (total ~$329,971).
- Shares involved: 16,853 RSUs converted to common stock; 6,883 shares withheld for taxes; net ~9,970 shares issued to Engel.
- Shares owned after transaction: not disclosed in the filing.
- Notable footnotes: RSUs were granted under the company’s 2021 Equity Incentive Plan. The converted RSUs were from the 2024 and 2025 grant dates; the withheld shares satisfy tax withholding and the issuer will pay the related taxes on Engel’s behalf (see F1–F4).
- Transaction codes: M = exercise/conversion of derivatives (conversion of RSUs); F = shares withheld to cover taxes.
Context
- This was not an open‑market sale; it was a routine conversion/settlement of RSUs that vested according to their time‑based schedules (three equal annual installments per the grant agreements). Because shares were withheld to cover taxes, the transaction resembles a cashless settlement of vested awards rather than a sale indicating a change in sentiment.
