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.

Amkor Technology, Inc. (AMKR) – Transazione interna Form 4

Il direttore David N. Watson ha presentato un modulo Form 4 segnalando un acquisto di 38,5269 unità azionarie vincolate (RSU) in data 25 giugno 2025. Le RSU sono state accumulate automaticamente come unità equivalenti ai dividendi (DEU) collegate a una precedente assegnazione di RSU con maturazione temporale datata 15 maggio 2025. In linea con il funzionamento delle DEU, il prezzo di transazione è indicato a $0 e mantiene le stesse condizioni di maturazione del premio sottostante.

A seguito dell'accredito di queste DEU, la proprietà effettiva di Watson in titoli derivati legati alle azioni ordinarie Amkor è aumentata a 9.827,5269 RSU, tutte detenute direttamente. Non sono state vendute azioni né è stato scambiato denaro sul mercato aperto.

La dichiarazione non fa riferimento a un piano di trading Rule 10b5-1 e non mostra variazioni nella proprietà di azioni non derivate. Considerata la piccola entità della concessione incrementale rispetto alla posizione esistente di Watson e al numero di azioni Amkor, l'evento è ordinario e non si prevede che abbia un impatto significativo sulla struttura del capitale della società o sul sentiment degli insider.

El director David N. Watson presentó un Formulario 4 reportando una adquisición de 38.5269 unidades restringidas de acciones (RSU) el 25 de junio de 2025. Las RSU se acumularon automáticamente como unidades equivalentes a dividendos (DEU) vinculadas a una concesión previa de RSU con vencimiento por tiempo fechada el 15 de mayo de 2025. Conforme a la mecánica de las DEU, el precio de la transacción se registra en $0 y mantiene las mismas condiciones de adquisición que el premio subyacente.

Tras el abono de estas DEU, la propiedad beneficiaria de Watson en valores derivados vinculados a acciones ordinarias de Amkor aumentó a 9,827.5269 RSU, todas mantenidas directamente. No se vendieron acciones ni se intercambió efectivo en el mercado abierto.

La presentación no menciona un plan de negociación bajo la Regla 10b5-1 y no muestra cambios en la propiedad de acciones no derivadas. Dado el pequeño tamaño de la concesión incremental en relación con la posición existente de Watson y el número de acciones de Amkor, el evento es rutinario y no se espera que tenga un impacto material en la estructura de capital de la empresa o en el sentimiento de los insiders.

이사 David N. Watson2025년 6월 25일38.5269개의 제한 주식 단위(RSU) 취득을 보고하는 Form 4를 제출했습니다. 이 RSU는 2025년 5월 15일에 부여된 시간 기반 RSU에 연동된 배당금 등가 단위(DEU)로 자동 적립되었습니다. DEU의 특성에 따라 거래 가격은 $0로 기재되었으며, 기본 부여 조건과 동일한 베스팅 규정을 따릅니다.

이 DEU가 적립된 후 Watson의 Amkor 보통주 관련 파생증권 실소유량은 9,827.5269 RSU로 증가했으며, 모두 직접 보유하고 있습니다. 주식 매도나 공개 시장에서 현금 교환은 없었습니다.

해당 신고서에는 Rule 10b5-1 거래 계획이 언급되지 않았으며, 비파생 주식 소유에는 변동이 없습니다. Watson의 기존 보유량과 Amkor 주식 수에 비해 이번 추가 부여 규모가 작아 이번 거래는 일상적인 사항으로 회사의 자본 구조나 내부자 심리에 중대한 영향을 미치지 않을 것으로 예상됩니다.

Amkor Technology, Inc. (AMKR) – Insider-Transaktion Form 4

Direktor David N. Watson reichte ein Form 4 ein, in dem er den Erwerb von 38,5269 Restricted Stock Units (RSUs) am 25. Juni 2025 meldete. Die RSUs wurden automatisch als Dividendenäquivalente Einheiten (DEUs) gutgeschrieben, die mit einer früheren Zuteilung von zeitlich vesteten RSUs vom 15. Mai 2025 verknüpft sind. Gemäß der DEU-Mechanik wird der Transaktionspreis mit 0 $ angegeben und unterliegt den gleichen Vesting-Bedingungen wie die zugrunde liegende Zuteilung.

Nach der Gutschrift dieser DEUs erhöhte sich Watsons wirtschaftliches Eigentum an derivativen Wertpapieren, die an Amkor-Stammaktien gebunden sind, auf 9.827,5269 RSUs, die alle direkt gehalten werden. Es wurden keine Aktien verkauft und kein Bargeld über den offenen Markt ausgetauscht.

Die Meldung verweist nicht auf einen Rule 10b5-1 Handelsplan und zeigt keine Änderung des Eigentums an nicht-derivativen Aktien. Angesichts der geringen Größe der zusätzlichen Zuteilung im Verhältnis zu Watsons bestehender Position und der Aktienanzahl von Amkor ist das Ereignis routine und wird voraussichtlich keine wesentlichen Auswirkungen auf die Kapitalstruktur des Unternehmens oder die Insiderstimmung haben.

Insights

TL;DR: Small, automatic DEU accrual—neutral for AMKR investors.

The transaction is administratively triggered by Amkor’s June 25 dividend, adding 38.53 RSUs to Director Watson’s account at no cost. Post-transaction ownership rises to 9,827.53 RSUs, indicating continued alignment but not a strategic buy. There are no sales, no option exercises, and no cash proceeds. Given the de-minimis size versus Amkor’s ~246 million shares outstanding and lack of new information on operations or guidance, I view the filing as neutral with negligible market impact.
