AMKR - Amkor Technology, Inc.

Amkor Technology provides outsourced semiconductor assembly and test (OSAT) services, including advanced packaging formats such as flip-chip, wafer-level packaging, and system-in-package (SiP) used in smartphones, automotive electronics, and data center chips. The business model is B2B manufacturing services, selling to fabless semiconductor companies and integrated device manufacturers (IDMs) like Qualcomm, Apple supply chain partners, and Texas Instruments under volume purchase agreements. Amkor generates approximately $6.5B in annual revenue, with primary operations and customers concentrated in Asia (South Korea, Japan, Vietnam, Taiwan) and significant exposure to the consumer electronics and mobile end markets. The company competes in a capital-intensive contract manufacturing segment alongside ASE Technology and JCET, and does not design or own the semiconductor IP it packages.

Past Year Trends

• Amkor Technology grew FY2025 revenue 6% YoY to $6.71 billion, driven by a record Q3 2025 at $1.99 billion as AI/HPC advanced packaging demand accelerated, with advanced products exceeding 80% of total revenue by Q4 2025. (Bullish)
• Gross margin compressed to 14.0% in FY2025 from 14.8% in FY2024 despite higher revenues, reflecting an unfavorable product mix shift during the ramp of high-volume advanced packaging lines and pricing pressure. (Bearish)
• Amkor broke ground in October 2025 on a $7 billion advanced packaging campus in Peoria, Arizona — expanded from an initial $2 billion commitment — with Apple and Nvidia named as anchor customers, and secured up to $400 million in proposed U.S. CHIPS Act funding. (Bullish)

Next Year Trends

• Amkor's 2.5D and High-Density Fan-Out (HDFO) advanced packaging platforms are projected to nearly triple in 2026, with the computing segment alone expected to grow more than 20% YoY as Nvidia and Apple ramp AI accelerator and silicon packaging volumes through Amkor's existing Southeast Asia facilities. (Bullish)
• Amkor's 2026 capital expenditure of $2.5–$3.0 billion — roughly three to four times 2025 spending — will heavily burden free cash flow through at least 2027, with the Arizona campus not entering production until early 2028, creating a multi-year period of elevated capex before the facility contributes meaningful revenue. (Bearish)
• Amkor's communications segment, which grew 42% YoY in Q1 2026, is heavily concentrated around Apple silicon packaging; any shift by Apple toward in-house or TSMC-integrated packaging solutions in future iPhone or Mac chip generations represents a direct revenue concentration risk unique to Amkor's customer mix.
