Rhea-AI Filing Summary

Form 4 highlights: On 08/01/2025 Sujoda Investments, LP—controlled by Sujoda Management, LLC, a member of the Kim 10%-owner group�received 441,589 AMKR common shares at an implied $21.85 per share (� $9.7 m). The transfer was coded “P,� but the footnote clarifies it was an in-family distribution from James J. Kim rather than an open-market buy. After the transaction, Sujoda Investments� indirect stake rose to 3,789,479 shares.

The reporting entity elects to treat all Sujoda Investments shares as beneficially owned, yet expressly disclaims beneficial ownership beyond its pecuniary interest. No derivative positions were reported.

Takeaway for investors: The filing increases transparency around the Kim family’s internal reallocation of a sizable position (~1.7 % of AMKR’s 264 m shares outstanding). While it signals continued concentrated insider ownership, the non-cash nature of the transfer limits immediate market impact.

Kim, e non di un acquisto sul mercato aperto. Dopo la transazione, la partecipazione indiretta di Sujoda Investments è salita a 3.789.479 azioni.

L'entità che ha effettuato la comunicazione sceglie di considerare tutte le azioni di Sujoda Investments come di proprietà effettiva, pur rinunciando espressamente a qualsiasi diritto di proprietà effettiva oltre il proprio interesse pecuniario. Non sono state segnalate posizioni derivate.

Messaggio per gli investitori: La comunicazione aumenta la trasparenza riguardo alla riallocazione interna alla famiglia Kim di una posizione significativa (~1,7% delle 264 milioni di azioni AMKR in circolazione). Pur indicando una proprietà concentrata e continuativa da parte degli insider, la natura non monetaria del trasferimento limita l'impatto immediato sul mercato.

Formular 4 Highlights: Am 01.08.2025 erhielt Sujoda Investments, LP � kontrolliert von Sujoda Management, LLC, einem Mitglied der Kim 10%-Eigentümergruppe � 441.589 AMKR-Stammaktien zu einem impliziten Kurs von 21,85 $ pro Aktie (� 9,7 Mio. $). Die Übertragung wurde mit „P� codiert, aber die Fußnote stellt klar, dass es sich um eine innerfamiliäre Zuteilung von James J. Kim handelte und nicht um einen Kauf am offenen Markt.

Fazit für Investoren: Die Meldung erhöht die Transparenz bezüglich der internen Umverteilung einer erheblichen Position (~1,7 % der 264 Mio. ausstehenden AMKR-Aktien) innerhalb der Familie Kim.

Negative
  • None.

Insights

TL;DR: Internal share transfer boosts Sujoda’s stake; neutral for AMKR fundamentals.

The 441.6 k-share distribution, though valued near $10 m, is a zero-sum shift inside the Kim family group. No cash leaves or enters Amkor, and the transaction does not alter share count or company liquidity. Insider accumulation can be viewed positively for alignment, but here it reflects estate/partnership structuring rather than a conviction buy. Given Amkor’s 3-month ADV of ~800 k shares, the stake size is material but the nature of the transfer is unlikely to influence trading dynamics or valuation.

TL;DR: Filing maintains Rule 16 compliance; no new control implications.

Sujoda Management remains part of the disclosed 10 % owner group; the updated indirect holdings keep collective ownership levels largely unchanged. The disclaimer of beneficial ownership beyond pecuniary interest is standard and prevents unintended control attributions. Overall, the event is administrative—important for transparency but not impactful to governance risk or voting power dynamics.
