It just posted one of its worst trading days in years, and the AI boom's headlines barely noticed.*\n\nShares of Amkor Technology fell 22.9% on July 28, 2026. The company had just guided third-quarter revenue to $1.95 billion to $2.05 billion, well short of the roughly $2.12 billion Wall Street expected. The stock kept sliding. It now trades around $50, down close to half from its 52-week high of $96.68, according to data reported by stockanalysis.com and Investing.com.\n\nThat's a brutal fall for a company most people have never heard of, even though it sits at the center of nearly every chip that reaches your phone, laptop or data center. Amkor is the world's largest outsourced semiconductor packaging and test provider. TSMC makes the silicon. Amkor packages it, tests it and ships it out the door. Without that step, none of Nvidia's AI chips or Apple's processors become a finished product.\n\nManagement blamed the shortfall on a manufacturing migration of its own making. Amkor is shifting system-in-package production out of South Korea and into Vietnam, and executives said on the July 28 earnings call that the move will keep weighing on results through the fourth quarter of 2026 and into early 2027. Soft memory demand made it worse. The company's Q3 earnings-per-share guide of $0.72 to $0.82 also landed below what analysts had penciled in, even though Q2 itself was a record quarter, with revenue of $1.90 billion and gross margin expanding to 16.8%.\n\nHere's the part that should worry anyone tracking the AI trade: this wasn't a demand problem. It was Amkor tripping over its own supply chain while everyone else's supply chain depends on it.\n\n[Hackers Minted 329 Trillion Fake SAND Tokens and Walked Away With $675,000](https://startupfortune.com/hackers-minted-329-trillion-fake-sand-tokens-and-walked-away-with-675000/)\n\nAttackers exploited a LayerZero delegate-permission flaw in The Sandbox's cross-chain SAND bridge on August 22, minting tokens worth $49 billion on paper across Base and BNB Chain. The real loss was about $675,000, roughly 14.75 million SAND drained and converted to 80 ETH before The Sandbox shut down bridging on the affected chains. - [how hackers exploited LayerZero cross chain bridge bug](https://startupfortune.com/hackers-minted-329-trillion-fake-sand-tokens-and-walked-away-with-675000/) - [SAND token 329 trillion fake tokens minted exploit](https://startupfortune.com/hackers-minted-329-trillion-fake-sand-tokens-and-walked-away-with-675000/)\n\nThe stock had already been showing cracks before July. At its May 21 investor day, Amkor's management, led by CFO Megan Faust, laid out long-term targets that underwhelmed the Street: revenue above $9 billion and EPS of roughly $2.50 by 2028, then revenue topping $11 billion and EPS above $5 by 2030, compared with actual EPS of just $1.50 in 2025. Those numbers sound like growth. They just weren't the numbers analysts had modeled in, and the targets got a cool reception even before the July guidance miss piled on.\n\n## The AI deals keep coming, the execution doesn't match\n\nWhat makes the drop strange is that Amkor's position in the AI supply chain has never looked stronger on paper. In June, Amkor and TSMC formalized a 10-year deal to build advanced packaging capacity in Peoria, Arizona. It's a $7 billion facility. It targets 2028 production and covers technologies like Integrated Fan-Out and Chip on Wafer on Substrate - the packaging methods that power Nvidia's AI accelerators. More recently, Nvidia itself agreed to a $1.5 billion multi-year deal that includes a prepayment to help fund Amkor's US advanced packaging expansion.\n\nFrankly, that's the disconnect nobody's writing about. The company landing money from Nvidia to build out American AI packaging capacity is the same company that just told investors its near-term numbers are falling apart because of a factory move it chose to make. Wall Street's reaction has been split rather than uniform. B. Riley cut its price target to $65 from $75 while keeping a Neutral rating, and other firms raised targets by anywhere from $5 to $25 on the back of the Nvidia and TSMC deals, according to coverage tracked by Simply Wall St.\n\nYou don't get a stock that's down nearly half from its highs and still landing billion-dollar AI infrastructure deals very often. Usually one of those facts is wrong. In Amkor's case, both are true at once, and that's exactly why this is worth watching instead of shrugging off as noise around Nvidia's next earnings call.\n\nPackaging capacity, not wafer fabrication, is increasingly the bottleneck in AI chip supply, and Amkor is one of a handful of companies capable of running it at scale outside Taiwan. A stumble here doesn't show up in a flashy Nvidia headline. It shows up months later, in a delayed shipment or a squeezed margin at whichever company was counting on packaged chips arriving on schedule. Amkor declared its regular quarterly dividend on August 12, a signal management isn't panicking internally even as the stock keeps drifting lower. Investors clearly aren't taking that as reassurance yet.\n\n**Also read:** [Hackers Minted 329 Trillion Fake SAND Tokens and Walked Away With $675,000](https://startupfortune.com/hackers-minted-329-trillion-fake-sand-tokens-and-walked-away-with-675000/) • [Google's Gemma Models Just Hit a Billion Downloads and Wall Street Shrugged](https://startupfortune.com/googles-gemma-models-just-hit-a-billion-downloads-and-wall-street-shrugged/) • [Nvidia Warns Hyperscalers Its AI Server Prices Are Jumping More Than 15%](https://startupfortune.com/nvidia-warns-hyperscalers-its-ai-server-prices-are-jumping-more-than-15/)", "url": "https://wpnews.pro/news/amkor-technology-shares-crash-as-chip-packaging-giant-misses-its-own-guidance", "canonical_source": "https://startupfortune.com/amkor-technology-shares-crash-as-chip-packaging-giant-misses-its-own-guidance/", "published_at": "2026-08-23 02:37:10+00:00", "updated_at": "2026-08-23 02:42:29.581654+00:00", "lang": "en", "topics": ["ai-infrastructure", "ai-chips", "ai-policy"], "entities": ["Amkor Technology", "TSMC", "Nvidia", "Apple", "Megan Faust", "Peoria, Arizona", "The Sandbox", "LayerZero"], "alternates": {"html": "https://wpnews.pro/news/amkor-technology-shares-crash-as-chip-packaging-giant-misses-its-own-guidance", "markdown": "https://wpnews.pro/news/amkor-technology-shares-crash-as-chip-packaging-giant-misses-its-own-guidance.md", "text": "https://wpnews.pro/news/amkor-technology-shares-crash-as-chip-packaging-giant-misses-its-own-guidance.txt", "jsonld": "https://wpnews.pro/news/amkor-technology-shares-crash-as-chip-packaging-giant-misses-its-own-guidance.jsonld"}}
