Shares of Amkor Technology fell 8.6% following the first quarter release as investors reacted to guidance that pointed to deceleration in key end markets and persistent margin pressures, particularly outside core communications. Cautious commentary around material pricing, delayed customer supplies, and softness in computing also weighed on sentiment despite record quarterly revenue.

• Q1 revenue hit a record $1.68 billion, up 27% year-over-year, with strength in communications (+42%) and automotive/industrial (+28%); computing rose 19% but was pressured by ongoing PC and laptop softness.
• Gross margin of 14.2% topped guidance, but operating margin remained modest at 6%, with management citing additional cost pressures from material pricing—especially related to geopolitical issues in the Middle East.
• Q2 outlook calls for only mid-single digit sequential growth across computing, automotive/industrial, and continued seasonal strength in communications; consumer is expected to rebound low double digits sequentially due to wearables.
• Management acknowledged ongoing risks from delayed customer supplies and nonlinear loading, as well as a dynamic macro and supply chain backdrop.
• Execution on advanced packaging program ramps and new capacity in Korea/Arizona remain on track for 2H26 but have yet to offset near-term investor concerns around margins and segment deceleration.
