Welcome to our dedicated page for AMKOR TECHNOLOGY SEC filings (Ticker: AMKR), a comprehensive resource for investors and traders seeking official regulatory documents including 10-K annual reports, 10-Q quarterly earnings, 8-K material events, and insider trading forms.
Amkor Technology Inc. filings document the regulatory record for a Nasdaq-listed outsourced semiconductor packaging and test company. The company’s 8-K reports furnish results of operations and financial condition, disclose material agreements and other events, and describe capital-structure matters involving common stock, senior notes and convertible senior notes.
AMKR filings also cover governance and ownership subjects through definitive proxy materials, officer appointments and underwriting agreements related to registered secondary offerings. Recent debt disclosures describe 0.00% convertible senior notes due 2031, subsidiary guarantees and their relationship to other senior unsecured indebtedness, while earnings-related filings include non-GAAP measures such as EBITDA alongside GAAP results.
Amkor Technology director Douglas A. Alexander received additional restricted stock units through dividend credits rather than market purchases. On March 31, 2026, he was granted three small blocks of dividend equivalent units tied to earlier RSU awards from 2022, 2023, and 2025. Each dividend equivalent unit converts into an additional RSU subject to the same vesting and other conditions as the original grants, modestly increasing his equity-based compensation while leaving cash holdings unchanged.
Amkor Technology, Inc. is asking stockholders to vote at its virtual 2026 Annual Meeting on May 13, 2026 at 11:30 a.m. EDT. Stockholders will elect 11 directors, approve on an advisory basis the compensation of named executive officers, and ratify the independent auditor.
Kevin K. Engel became President and Chief Executive Officer on January 1, 2026, succeeding retiring CEO Giel Rutten, who remains on the Board. For 2025, Amkor reports revenue of $6.7 billion, up 6% year on year, with growth across all end markets and record revenue in Computing and Advanced products.
The proxy describes a pay-for-performance program that reduced 2025 target bonuses by 25%, tied incentives to operating income and individual performance, and delivered payouts based on operating income of $343.9 million and EPS of $1.51 versus a $1.48 target. The Board highlights its majority of independent directors, a Lead Independent Director role, robust committee structure, stock ownership guidelines, anti-hedging and anti-pledging rules, and a clawback policy linked to financial restatements.
