The company’s balance sheet remains robust, with $1.5 billion in cash and a debt-to-EBITDA ratio of 1x, supporting ongoing capital investments.
End-market dynamics were mixed. Communications revenue rose 10% sequentially, led by premium smartphone launches, while computing jumped 20% on AI device strength and new ARM-based PCs. However, automotive and industrial revenue fell 2% sequentially, reflecting a slower recovery and inventory corrections. Consumer revenue dipped 6% sequentially, but a major wearable device launch is expected to drive a sharp rebound in Q3.
- Product Mix Impact: High material content in advanced SIP products constrained gross margin, though bottom-line earnings grew more than 80% sequentially into Q3 guidance.
- Capacity Expansion: 2.5D capacity more than tripled YoY, with full-year revenue from this segment expected to quadruple versus 2023.
- Operational Discipline: Cost controls offset low utilization in some factories, while Vietnam and Korea facilities ramped for new product launches.
Q3 is guided for a 26% sequential revenue increase, driven by advanced packaging for smartphones, wearables, and AI computing, but margin expansion will be tempered by product mix and material costs.
Executive Commentary
"We aligned on a non-binding preliminary memorandum of terms with the U.S. Department of Commerce for up to $400 million in grants under the CHIPS and Science Act. These funds will support building a new facility in Arizona, enabling advanced packaging and tests for high-performance computing, AI, communications, and automotive markets."

Strategic Positioning
1. Advanced Packaging Leadership
Amkor is aggressively scaling its 2.5D and advanced SIP capabilities, positioning itself as a vital enabler for AI, high-performance computing, and next-generation consumer devices. The company’s rapid capacity expansion and leadership in organic interposer technology are attracting a broadening customer base, with both silicon and organic interposer solutions set for mass production in 2025.
2. U.S. Manufacturing Expansion
The Arizona facility, supported by up to $400 million in CHIPS Act grants, marks a strategic move to localize advanced packaging in the U.S. and strengthen supply chain resilience. While the facility will represent less than 10% of total capacity, it is designed for scale and will mirror Amkor’s leading-edge operations in Korea, targeting high-performance computing and communications customers.
3. End-Market Diversification and Cyclicality
Amkor’s diversified exposure across communications, computing, automotive, and consumer markets provides resilience, but also exposes the company to cyclical swings. Current weakness in automotive and traditional data centers is being offset by robust demand in AI, ARM-based PCs, and consumer wearables, highlighting the importance of product and customer mix management.
