EVP & General Counsel · AMKOR TECHNOLOGY, INC. (AMKR)
This is the public record of open-market stock transactions Mark N. Rogers has reported to the SEC on Form 4 as EVP & General Counsel of AMKOR TECHNOLOGY, INC. (AMKR). Every figure below is the reported share count multiplied by the reported price, so the dollar amounts are exact disclosed values rather than estimates. It is a record of what has been filed, not a portfolio or a recommendation, and insider selling in particular is routine and rarely a signal on its own.
Most of Mark N. Rogers's sales were pre-scheduled or tax-related rather than discretionary, which further weakens any read of them as a market call.
All 8 disclosed transactions, newest filing first.
How many shares has Mark N. Rogers bought and sold?
Mark N. Rogers has disclosed 8 Form 4 transactions in the record we track, from Jul 31, 2025 to Aug 17, 2026: 8 sales worth $3,557,377 and no open-market purchases. Each figure is the reported share count multiplied by the reported price, so these are exact disclosed amounts, not estimates.
Is Mark N. Rogers selling a bearish signal?
Not on its own. Insiders sell for many reasons that have nothing to do with a view on the stock — diversification, taxes, estate planning, or a pre-scheduled plan set up months earlier. Of the 8 sales on this record, 7 were made under a Rule 10b5-1 plan and 0 were automatic tax withholding on vesting shares, leaving 1 that were the insider's own discretionary decision (worth $353,727). Buying is the cleaner signal, because there is only one reason to buy. This page is a record, not a recommendation.
