Amkor Technology, Inc. reported a net sales increase of $390.3 million, or 6.2%, for the fiscal year ending December 31, 2025, reaching $6.7 billion compared to $6.3 billion in 2024. The growth was attributed to higher sales across all end markets, particularly in computing, which saw a 16% increase driven by demand for AI-related devices and networking infrastructure. The automotive and industrial sectors also experienced an 8% rise, largely due to advanced driver assistance systems (ADAS) applications. However, the company's gross margin decreased to 14.0% from 14.8% in the previous year, primarily due to increased overhead and employee compensation costs, despite higher factory utilization.
In terms of strategic developments, Amkor has been expanding its manufacturing footprint, notably with the construction of a new facility in Arizona, which began in the second half of 2025. This facility is expected to enhance Amkor's ability to serve customers looking to regionalize their supply chains. Additionally, the company has been scaling production at its Vietnam facility, which opened in 2024, further increasing operational flexibility. The total capital expenditures for 2025 amounted to $904.6 million, representing 13.5% of net sales, with a focus on advanced packaging and test equipment.
Operationally, Amkor's workforce stood at approximately 30,800 employees as of December 31, 2025, with a significant majority located in the Asia-Pacific region. The company reported that its ten largest customers accounted for 72% of net sales, with Apple and Qualcomm being the most significant, contributing 29.8% and 11.1% of total sales, respectively. The company also noted a substantial increase in contract liabilities, which rose to $390.8 million, reflecting higher customer advance payments.
Looking ahead, Amkor anticipates capital expenditures of approximately $2.5 billion to $3.0 billion for 2026, primarily driven by the Arizona facility's construction. The company remains focused on leveraging its technology leadership and expanding its geographic footprint to capture growth in high-value markets such as high-performance computing, automotive, and IoT. However, Amkor's business is subject to the cyclical nature of the semiconductor industry, and the company acknowledges the potential impact of economic fluctuations on its operations and financial performance.
