Current report

Amkor is a global leader in advanced semiconductor packaging and test technologies. Our technology leadership encompasses areas such as high density fan-out (“HDFO”), 2.5D integration, advanced flip chip, fine pitch bumping, wafer-level processing and advanced system-in-package (“SiP”) solutions which support the industry’s drive toward smaller form factors, higher integration, improved performance and lower power consumption. We provide turnkey solutions that include package design, wafer bump, wafer probe, wafer back-grind, packaging, burn-in, system level and final test and drop shipment services. Our extensive line of packaging and test services covers analog, digital, logic, mixed signal, memory, sensors and radio frequency devices. This breadth of services allows customers to limit the number of suppliers and focus their resources on semiconductor design and wafer fabrication. Our commitment to technology leadership is reinforced by ongoing investment in research and development, and we intend to continue to leverage our investments in advanced technology to meet the demand for these services in key markets.

Current report

Amkor’s broad and strategically located manufacturing footprint is a key differentiator, enabling us to deliver flexible, resilient and cost-effective solutions to customers worldwide. With facilities located in key manufacturing regions in Asia and Europe, we provide customers with multiple options to mitigate risk, diversify supply chains and support regionalization initiatives. As a U.S. headquartered OSAT, we are expanding our manufacturing footprint with the construction of a new facility in Arizona. Construction began in the second half of 2025, and we believe that this investment will strengthen our ability to serve customers seeking to regionalize their supply chains and will enhance our participation in U.S. semiconductor initiatives. In addition, we continue to scale production in our Vietnam facility, which opened in 2024, further increasing our capacity and operational flexibility in Asia. Our scale and geographic diversity allow us to qualify production at multiple sites, optimize asset utilization and absorb large orders with quick turnaround times.

Current report

Amkor has built long-standing relationships with most of the world’s leading semiconductor companies over the last five decades. Our operational excellence, high quality, reliability and predictability have been key to attracting and retaining customers. Our collaborative approach enables us to work closely with customers and suppliers to co-develop proprietary process technologies, accelerate time-to-market, improve quality and lower costs. We work closely with lead customers to deliver advanced packaging solutions tailored to evolving industry needs.

Previous report

We believe that demand for advanced packaging services will continue to grow as our customers and leading electronics original equipment manufacturers strive for smaller device geometries, higher levels of integration and performance and lower power consumption. We intend to continue to leverage our investments in advanced technology to meet the demand for these services in high growth markets.

Previous report

Our broad geographic footprint, including our manufacturing presence in multiple countries across Asia, in Portugal and our headquarters in the United States, is a key differentiator and positions us well to support evolving global supply chains, including initiatives to regionalize supply chains. We began delivering advanced packages from the Vietnam Facility in the third quarter of 2024. In addition, we were awarded up to $407 million in direct funding by the U.S. Department of Commerce (“Commerce”) pursuant to the U.S. CHIPS and Science Act of 2022 (“CHIPS Act”) to support the Arizona Facility, conditioned on, among other things, the achievement of certain construction and production milestones. We acquired the land for the Arizona Facility in 2024, which we expect to exchange for another parcel of land in the fourth quarter of 2025. Activities to prepare the site for construction commenced in September 2025. We believe our broad geographic footprint provides customers with multiple options to mitigate risk and diversify their supply chains.

Previous report

Another key factor in our results of operations is the optimization of asset utilization. We build and utilize manufacturing lines which support multiple customers, and we increase factory utilization through sophisticated planning processes and intensive efficiency improvement activities.

Previous report

Previous report

Selling, general and administrative expenses decreased for the nine months ended September 30, 2025 compared to thenine months ended September 30, 2024, primarily due to net cash received in the Nanium Insolvency Receipt and the incremental costs incurred in 2024 during start-up at the Vietnam Facility. The amount recognized from the Nanium Insolvency Receipt for the nine months ended September 30, 2025, net of amounts remitted to the selling shareholders, was $32.4 million. The incremental costs incurred during start-up at the Vietnam Facility were approximately $28 million for the nine months ended September 30, 2024. For additional information regarding the Nanium Insolvency Receipt, please refer to Note 15 to our Consolidated Financial Statements in Part 1, Item 1 of this Form 10-Q.

Previous report

Interest expense increased for the three and nine months ended September 30, 2025 compared to the three and nine months ended September 30, 2024, primarily due to an increase in our average outstanding debt related to the issuances of the 2033 Notes and the Term A Loans, which were used in part to redeem all amounts outstanding under our 2027 Notes and AATS Loans.

Previous report

Interest income decreased for the nine months ended September 30, 2025 compared to the nine months ended September 30, 2024, primarily due to lower interest rates partially offset by increases in our cash and cash equivalent and available-for-sale debt investment balances.

Previous report

The changes in foreign currency (gain) loss, net for the three months ended September 30, 2025 compared to the three months ended September 30, 2024 were primarily due to the weakening of the U.S. dollar compared to the foreign currencies of our subsidiaries and the associated impact on our unhedged net monetary exposures in 2024.

Previous report

In September 2025, we issued $500.0 million of the 2033 Notes. Additionally, in October 2025, we redeemed the outstanding $400.0 million aggregate principal amount of our 2027 Notes. The redemption was funded from our issuance of the 2033 Notes.
