Insights

Equity Markets & Insider Transactions Analyst

Routine Rule 144 filing for a 10,000-share planned AMKR sale.

The notice describes a planned resale of 10,000 shares of AMKR common stock under Rule 144, using Morgan Stanley Smith Barney LLC as broker on NASDAQ around 01/15/2026. Rule 144 filings are typically administrative disclosures that allow affiliates or large holders to sell restricted or control securities in the public market subject to volume and other conditions.

The form shows the shares come from restricted stock awards acquired from the issuer on 02/24/2024 and 02/16/2024, and notes prior sales of 20,000 shares in the past three months with gross proceeds of 448,039.00 and 316,791.00. With 247,193,437 common shares outstanding, the planned 10,000-share sale is small in percentage terms, so on the information provided this appears to be a routine liquidity transaction rather than a thesis-changing event.
