Rhea-AI Filing Summary

Form 4 highlight: On 01-Aug-2025 the "2023 Grantor Retained Annuity Trust of Agnes C. Kim" executed two Code G (bona-fide gift) transactions involving Amkor Technology (AMKR) common stock.

  • Gifted 280,000 shares to Susan Y. Kim.
  • Gifted 280,001 shares to John T. Kim.

No cash consideration was received (price $0). The trust’s direct beneficial ownership fell from 560,001 shares to zero. The filing states that the trust does not concede beneficial ownership of shares now held by other group members.

Because the transfers are intra-family gifts rather than open-market sales, trading supply is unchanged. Still, investors may note that one insider vehicle has fully exited its direct position, marginally reducing reported insider ownership.

Riepilogo del Modulo 4: Il 01-agosto-2025 il "2023 Grantor Retained Annuity Trust di Agnes C. Kim" ha effettuato due transazioni Codice G (donazione autentica) riguardanti azioni ordinarie di Amkor Technology (AMKR).

  • Ha donato 280.000 azioni a Susan Y. Kim.
  • Ha donato 280.001 azioni a John T. Kim.

Non è stata ricevuta alcuna contropartita in denaro (prezzo $0). La proprietà diretta del trust è passata da 560.001 azioni a zero. La dichiarazione specifica che il trust non rinuncia alla proprietà effettiva delle azioni ora detenute da altri membri del gruppo.

Poiché i trasferimenti sono donazioni intra-familiari e non vendite sul mercato aperto, l'offerta di azioni sul mercato non cambia. Tuttavia, gli investitori possono notare che un veicolo interno ha completamente ceduto la sua posizione diretta, riducendo leggermente la proprietà interna riportata.

Resumen del Formulario 4: El 01 de agosto de 2025, el "2023 Grantor Retained Annuity Trust de Agnes C. Kim" realizó dos transacciones Código G (donación genuina) que involucraron acciones comunes de Amkor Technology (AMKR).

  • Donó 280,000 acciones a Susan Y. Kim.
  • Donó 280,001 acciones a John T. Kim.

No se recibió contraprestación en efectivo (precio $0). La propiedad directa del fideicomiso disminuyó de 560,001 acciones a cero. La presentación indica que el fideicomiso no renuncia a la propiedad beneficiaria de las acciones que ahora poseen otros miembros del grupo.

Dado que las transferencias son regalos dentro de la familia y no ventas en el mercado abierto, la oferta de acciones en el mercado no cambia. Sin embargo, los inversores pueden notar que un vehículo interno ha salido completamente de su posición directa, reduciendo marginalmente la propiedad interna reportada.

Formular 4 Zusammenfassung: Am 01. August 2025 führte der "2023 Grantor Retained Annuity Trust von Agnes C. Kim" zwei Code G (echtgeschenkte) Transaktionen mit Stammaktien von Amkor Technology (AMKR) durch.

  • 280.000 Aktien wurden an Susan Y. Kim geschenkt.
  • 280.001 Aktien wurden an John T. Kim geschenkt.

Es wurde keine Barzahlung erhalten (Preis $0). Das direkte wirtschaftliche Eigentum des Trusts sank von 560.001 Aktien auf null. Die Meldung stellt klar, dass der Trust das wirtschaftliche Eigentum an den Aktien, die nun von anderen Gruppenmitgliedern gehalten werden, nicht aufgibt.

Da es sich bei den Übertragungen um innerfamiliäre Schenkungen und nicht um Verkäufe am offenen Markt handelt, ändert sich das Handelsangebot nicht. Dennoch könnten Investoren feststellen, dass ein Insidervehikel seine direkte Position vollständig aufgegeben hat, was den gemeldeten Insiderbesitz leicht verringert.

Positive
  • None.
Negative
  • Trust reduced its direct AMKR holdings by 560,001 shares, eliminating its stake

Insights

TL;DR Intra-family gifts; trust exits 560 k-share stake, minimal market impact.

The transactions are classified under Code G, confirming they are non-market gifts at $0. Although 560,001 shares represent roughly 0.23 % of AMKR’s outstanding shares, the lack of sale pressure means limited short-term price effect. The trust’s exit does, however, reduce the aggregate reported insider position, which some investors track for sentiment. Overall impact is neutral.

TL;DR Estate-planning move; ownership shifts but governance control unchanged.

The shares move from a GRAT to beneficiaries while remaining under the Kim family sphere; Susan Y. Kim is both recipient and sole trustee. There is no implication of strategic disagreement or loss of board influence. Disclosure language preserves distance regarding group beneficial ownership, a standard legal safeguard. Governance risk appears unchanged; materiality to outside shareholders is low.
