Amkor Technology stock jumped 12.2% to $73.30 in after-hours trading Thursday after the company announced a multi-year strategic partnership with Nvidia worth $1.5 billion. The stock had closed the regular session at $65.33, down 2.45%.
Under the deal, Nvidia will provide a prepayment to support the build-out of Amkor’s advanced packaging and test operations in the United States, with a focus on its Arizona facility.
The two companies will align their long-term technology roadmaps, targeting high-density interconnects and next-generation heterogeneous chip integration — capabilities that are increasingly critical as AI chip demand continues to outpace supply.

Amkor CEO Kevin Engel said: “This strategic partnership with NVIDIA underscores the central role advanced packaging plays in enabling the future of AI.”
This is not a new relationship. Amkor has been a longstanding supplier of advanced packaging for Nvidia’s data center processors. But this deal significantly expands that collaboration.
The announcement also follows Amkor’s June 2026 agreement — a 10-year deal with TSMC for advanced packaging in Arizona. That deal, combined with the Nvidia partnership, marks a clear shift for Amkor from a traditional outsourced semiconductor assembly provider to a strategic AI infrastructure partner.
Amkor is scheduled to release its Q2 2026 results after market close on Monday, July 27. In Q1, the company beat on both revenue and EPS — revenue came in 1.98% above estimates and EPS topped forecasts by 37.50%.
The Nvidia deal adds meaningful revenue visibility heading into that report.
B. Riley Securities maintained a Neutral rating on Amkor Wednesday but lowered its price target from $90 to $75. That target is now sitting just above Thursday’s after-hours price of $73.30.
Amkor has a market cap of $16.19 billion. Its 52-week range runs from $20.87 to a high of $96.66. The stock has gained 203.58% over the past 12 months.
The RSI stands at 43.11, and the stock is currently sitting at 58.66% of its 52-week trading range.
The broader market was muted Thursday, with the S&P 500 up 0.2%, the Dow up 0.5%, and the Nasdaq up 0.2% — none of which explains the scale of Amkor’s move.
The Nvidia prepayment deal provides both revenue certainty and strategic validation for Amkor’s U.S. expansion push ahead of Monday’s earnings report.
