STMicroelectronics, sold off last week as an AI loser, argues its own fabs are the hedge; carmakers and fabless rivals carry the bill. The chip bosses who feed the car industry gathered in Munich this week and described the same squeeze. Stefan Tilger, interim CEO of Nexperia, the Dutch maker of the diodes and transistors every vehicle uses, [told Reuters at the Electronica trade fair](https://www.msn.com/en-us/money/companies/chipmakers-warn-ai-demand-is-creating-bottlenecks-in-automotive-supply-chain/ar-AA2h98Lc) that his order book is "totally oversubscribed" because suppliers are diverting capacity toward AI data centers. "The automotive industry is suffering at the moment quite heavily," he said. His rival across the panel, [STMicroelectronics](https://theinference.org/markets/companies/stmicroelectronics) CEO Jean-Marc Chery, said foundries and packaging houses are "disengaging" from the mature technologies cars run on. "We see many bottlenecks," Chery said [1]. ## The bill already has a number Aumovio, the former Continental unit supplying radar sensors and cockpit electronics to BMW, Volkswagen, Ford and BYD, [expects a gross earnings hit of about €1 billion in 2027](https://www.cnbctv18.com/auto/bmw-supplier-warns-ai-data-centre-boom-could-add-e1-billion-to-auto-costs-in-2027-20028504.htm), mainly from semiconductor inflation [2]. Interim finance chief Claus Bauer called the cost dynamic "mind-boggling" and said data-center buyers show "no price sensitivity whatsoever" [2]. [Memory makers are already reporting operating margins near 80 percent](https://mlq.ai/news/nexperia-and-stmicroelectronics-warn-ai-demand-is-creating-bottlenecks-in-automotive-chip-supply/) as AI servers absorb DRAM and NAND [4]. AI buyers pay whatever the rack costs; the car buyer funds both. ## The stock that got the story backwards Three days before the Munich warnings, the market [sold STMicroelectronics 9.3 percent as an AI-fear stock](https://theinference.org/article/stmicroelectronics-fell-9-3-on-ai-buildout-fears-it-expects-1-3-billion-of-ai-revenue-under-a-tenth), though data centers bring it under a tenth of revenue [3]. On November 11 it [rebounded 4.68 percent to €41.98](https://www.ideal-investisseur.fr/en/stock-news/stmicroelectronics-tops-the-cac-40-with-a-rebound-of-nearly-5/29149.html) after a 9.81 percent one-month slide [5]. Chery's answer is ownership: "We control a part of our future with our CapEx and our manufacturing" [1]. *Chart: **STMicro's revenue climbed through the auto squeeze, back above 2024 levels** Column chart of STMicroelectronics quarterly net revenues across eight quarters, rising from a Q1 2025 trough of $2.5 billion to $3.76 billion in Q3 2026* *Quarterly net revenues, USD billions, per STMicroelectronics SEC filings, retrieved November 11, 2026. [7]* The quarter backs him up so far: [revenue of $3.76 billion, up 17.9 percent](https://www.msn.com/en-us/money/general/stmicro-lifts-data-centre-revenue-forecast-after-q3-profit-beat/ar-AA2gjSQN), operating income more than doubled to $367 million, gross margin up to 37.3 percent, and a Q4 guide of $4.15 billion at about 39 percent [6]. *Chart: **Margins are recovering, but operating profit is still half its late-2024 level** Line chart of STMicroelectronics gross and operating margin across eight quarters, gross margin dipping to 33.3 percent in late 2025 before recovering to 37.3 percent in Q3 2026, operating margin swinging from negative 4.8 percent to 9.8 percent* *Gross and operating margin, percent of revenue, per STMicroelectronics SEC filings, retrieved November 11, 2026. [8]* ## Who carries the risk Nexperia sits on the wrong side of its own warning: a narrower, mature-node catalog with no captive fab cushion, still tangled in a control fight with its Chinese parent Wingtech [4]. The test of Chery's bet comes in January, when Aumovio's annual supplier contracts reset and the €1 billion starts finding its way into car prices [2]. ## Takeaway AI data-center demand is pulling foundry and packaging capacity away from automotive chips, and Aumovio has already priced the damage at €1 billion for 2027; STMicro's captive fabs look like the hedge, and the market's 9.3 percent selloff may have read the story backwards. ## Sources 1.
