Context This was a large, institutional block sale executed through an underwritten secondary offering rather than a routine open-market trade. As a reported 10% owner (an institutional holder) rather than a company executive, this transaction reflects a significant liquidity event by a major shareholder; it should be viewed as an institutional disposition rather than a direct signal about Amkor’s near-term operations. Form 4 reporting documents the sale but does not explain the seller’s motivations.
