Amkor and Nvidia sign $1.5 billion chip packaging deal

Nvidia will prepay $1.5 billion to Amkor Technology to expand US advanced semiconductor packaging capacity, as chip assembly — not just fabrication — becomes a critical constraint in AI supply chains.

"Amkor's global capabilities, combined with their committed investment in the United States, are critical components of building resilient AI infrastructure and accelerating next-generation technologies," Debora Shoquist, executive vice president of operations at Nvidia, said.

The multi-year agreement covers joint development of high-density interconnects and heterogeneous integration — techniques that combine multiple silicon dies into a single package. Amkor already supplies packaging for Nvidia's data center processors, networking chipsets and accelerated computing systems. The expanded deal follows a 10-year packaging partnership Amkor signed with Taiwan Semiconductor Manufacturing Co. in June and its existing work with Advanced Micro Devices.

Amkor shares surged 17% in after-hours trading on the July 23 announcement but have since fallen 53% from a June peak of $96.68, closing at $45.69. The stock trades at 31.18 times forward earnings, a premium to the sector median, as investors weigh the long-term revenue opportunity against near-term valuation concerns.

The Packaging Bottleneck

Advanced packaging has become a major chokepoint in AI chip production. While companies like Nvidia rely on leading-edge fabrication at TSMC, they also need sufficient capacity to assemble multiple chips into high-performance AI systems. The $1.5 billion prepayment will help Amkor expand its planned advanced packaging and testing facility in Arizona, building domestic capacity for what has historically been an Asia-centric industry.

Amkor reported record second-quarter revenue of $1.9 billion on July 27, up 26% from a year earlier, driven by demand for advanced packaging used in AI and high-performance computing. Net income surged 222% to $174 million, or $0.70 per share, ahead of expectations. The company guided third-quarter revenue of $1.95 billion to $2.05 billion, with gross margin expected to improve to 18.5% to 19.5% from 16.8% in the second quarter. Management reaffirmed its 2026 capital expenditure plan of $2.5 billion to $3 billion, reflecting continued investment in advanced packaging capacity.

The deal also strengthens Amkor's competitive position against other outsourced semiconductor assembly and test providers. The company, which has a market capitalization of about $15 billion, is one of the world's largest OSAT providers and operates manufacturing facilities across Asia, Europe and the US. Its partnerships with Nvidia, TSMC and AMD give it a diversified customer base in the AI supply chain. CEO Kevin Engel said the agreement "accelerates our long-term roadmap" and supports turnkey packaging and test capability in the US alongside Amkor's Asian footprint.

Wall Street Weighs the Upside

Analysts are split on Amkor's valuation after the stock's 187% rally over the past 12 months. UBS upgraded the stock to Buy from Neutral on July 24 with a $90 price target, citing the Nvidia partnership as a driver for long-term growth. B. Riley Securities maintained a Neutral rating with a $75 target, pointing to valuation concerns after the stock's earlier run.

Of the 10 analysts covering Amkor, four rate it a Strong Buy, one a Moderate Buy and five a Hold, according to consensus data. The average price target of $75.75 implies 64% upside from current levels, while the Street-high target of $90 suggests potential gains of 94%.

For investors, the question is whether Amkor's expanded role in Nvidia's supply chain justifies its premium valuation. The company's forward P/E of 31x reflects expectations that AI-driven demand for advanced packaging will remain strong for years. But with the stock down more than 50% from its peak and five of 10 analysts on the sidelines, the market appears to be pricing in execution risk around the Arizona expansion and the pace of Nvidia's next-generation product cycles.
