Analysis · AMKR · Manufacturing
This amended Schedule 13D formally updates the beneficial ownership of the Kim Family Group following the previously announced secondary offering where 915 Investments, LP, a family investment vehicle, sold 10 million shares. The transaction, valued at approximately $484.9 million, represents a significant disposition by the controlling family, reducing their collective stake in Amkor Technology to just under 50%. This shift in ownership could have long-term implications for corporate governance and control, as the family's voting power is now below a simple majority.
