Executive Summary

Megan Faust, an officer of Amkor Technology, filed a Form 144 notice of intent to sell 1,000 shares of common stock, with an estimated aggregate market value of $46,920. The shares were acquired as performance-based equity awards. This is a small, routine sale relative to the company's market cap and the insider's likely holdings.

Key Facts

  • Megan Faust (officer) filed Form 144 to sell 1,000 shares of Amkor common stock.

  • Shares were acquired as performance shares on 12/31/2022.

Financial Impact
