Amkor CFO Reports Routine RSU Vesting, Minimal Share Disposition
Rhea-AI Filing Summary
Form 4 highlights: Amkor Technology’s Chief Financial Officer, Megan Faust, reported routine equity transactions dated 06/30/2025 related to previously granted Restricted Stock Units (RSUs) under the company’s 2021 Equity Incentive Plan.
- Vesting event: 8,691 RSUs vested and were automatically converted into an equal number of common shares (Transaction Code M). The vest carries a stated value of $0 in the filing because RSUs convert without cash consideration.
- Tax-withholding sale: To cover associated tax obligations, 3,725 shares were withheld by Amkor (Transaction Code F) at an indicated price of $20.99 per share.
- Net share change: After the two entries, Faust’s direct ownership decreased from 90,829 to 87,104 shares, a net reduction of 3,725 shares (the amount withheld for taxes). No open-market sale or purchase was executed by the insider.
- Remaining unvested RSUs: 34,768 units continue to vest in equal quarterly tranches on 09/30/2025, 12/31/2025, 03/31/2026, and 06/30/2026, completing the five-installment schedule.
Investor take-away: The filing reflects scheduled equity compensation activity rather than discretionary trading. Because the CFO retained the majority of vested shares and disposals were solely for statutory tax purposes, the transaction is generally viewed as neutral in terms of insider sentiment and should have limited impact on near-term share-price performance.
Positive

Insights
TL;DR Routine RSU vesting; tax-withholding disposal only; neutral governance signal.
The Form 4 shows compliance with Section 16 reporting requirements and standard tax-withholding mechanics. Code M indicates automatic RSU conversion, while Code F denotes share forfeiture to satisfy payroll tax. No discretionary sale was executed, suggesting the CFO is not reducing her economic exposure. Ownership remains sizable at 87,104 shares, aligning management’s incentives with shareholders. Governance risk is unchanged.
TL;DR Insider activity immaterial to thesis; maintain neutral stance on AMKR.
The 3,725-share disposal equals roughly 0.002% of Amkor’s 247 million outstanding shares—far below any materiality threshold. Withholding price of $20.99 is administrative, not a market sale. Remaining 34,768 RSUs will drip into float over the next year but represent negligible dilution (<0.02%). From a portfolio perspective, the transaction does not warrant position changes or valuation adjustments.
