Amkor Technology, Inc. (AMKR) – Form 4 filing
Director Gil C. Tily reported the automatic acquisition of 38.5269 restricted stock units (RSUs) on 25 June 2025. The RSUs were issued as dividend equivalent units (DEUs) linked to previously granted, time-vested RSUs dated 15 May 2025. Each DEU carries the same vesting conditions as the underlying award and was credited at no cash cost to the insider (price $0).
Following this routine dividend accrual, Tily’s total beneficial ownership increased to 9,827.5269 RSUs, held in direct form. No common shares were sold, and no option-like derivatives were exercised or disposed.
The transaction represents a 0.4% incremental increase to the insider’s existing RSU position and appears administrative rather than strategic. No immediate cash outlay was made, and there is no indication of market purchase or sale activity under Rule 10b5-1. Overall market impact is expected to be immaterial due to the small size relative to Amkor’s ~247 million outstanding shares.
Amkor Technology, Inc. (AMKR) – Form 4 insider transaction
Director David N. Watson filed a Form 4 reporting an acquisition of 38.5269 restricted stock units (RSUs) on 25 June 2025. The RSUs were accrued automatically as dividend-equivalent units (DEUs) linked to a prior grant of time-vested RSUs dated 15 May 2025. Consistent with DEU mechanics, the transaction price is listed at $0 and carries the same vesting provisions as the underlying award.
Following the crediting of these DEUs, Watson’s beneficial ownership in derivative securities tied to Amkor common stock increased to 9,827.5269 RSUs, all held directly. No shares were sold, and no open-market cash consideration was exchanged.
The filing does not reference a Rule 10b5-1 trading plan and shows no change in non-derivative share ownership. Given the small size of the incremental grant relative to Watson’s existing position and Amkor’s share count, the event is routine and not expected to have a material impact on the company’s capital structure or insider sentiment.
