Farshad Haghighi, Executive Vice President of Amkor Technology (AMKR), reported a sale of company stock on 09/09/2025. The filing shows a disposition of 11,792 shares at a reported price of $25 per share, leaving the reporting person with 8,354 shares beneficially owned after the transaction. The Form 4 is signed by an attorney-in-fact and records the transaction under Section 16.
Form 144 notice for Amkor Technology, Inc. (AMKR) shows a proposed sale of 11,792 common shares by an insider through Morgan Stanley Smith Barney, with an aggregate market value of $294,800 based on the filing. The shares represent part of previously acquired awards (restricted stock and performance shares) granted by the issuer between August 2024 and February 2025. The filing states the approximate sale date as 09/09/2025 on the NASDAQ and confirms no securities were reported sold by this person in the past three months.
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.
Form 4 filing for Amkor Technology (AMKR) discloses that Sujoda Investments, LP—an entity affiliated with the Kim family group—received 441,589 shares of AMKR common stock on 1-Aug-2025. The shares were transferred at a stated price of $21.85 per share and are coded “P,” indicating a purchase/distribution under Section 16 rules.
Following the transaction, Sujoda’s direct holdings rose to 3,789,479 shares. The filing states that the distribution was made by James J. Kim to Sujoda pursuant to an intra-family agreement; Sujoda’s general partner is Sujoda Management, LLC. The filing also clarifies that Sujoda does not concede beneficial ownership of securities held by other members of the Kim family group.
No derivative securities were reported, and no 10b5-1 trading plan was indicated. The change increases Sujoda’s position by roughly 13% versus its immediately prior holding, modestly tightening insider ownership concentration but without altering control status.
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.
