About STMicroelectronics
STMicroelectronics is one of Europe's largest semiconductor companies, making analog, power, sensing, and microcontroller chips. Automotive and industrial customers generate most of its revenue, with products ranging from silicon carbide power devices for electric vehicles to the widely used STM32 microcontroller family found across embedded electronics.
Its AI exposure runs on two tracks. In the data center, ST supplies power conversion silicon, including silicon carbide devices, and is developing 800 volt HVDC power delivery aligned with NVIDIA's AI factory architecture. At the edge, the STM32N6 microcontroller carries a built-in neural accelerator so AI can run on small, low-power devices, supported by the ST Edge AI Suite development tools.
Formed in 1987 from the merger of SGS Microelettronica and Thomson Semiconducteurs, ST employs about 49,000 people and its shares trade on the NYSE.
STMicroelectronics in the AI buildout
ST sits in the Semiconductors layer. Its data center role is power: converting and delivering electricity efficiently inside AI facilities, including silicon carbide devices and 800 volt HVDC work aligned with NVIDIA's next-generation architecture. Its second role is pushing AI outward to the edge, where STM32 microcontrollers with neural accelerators let inference run on sensors, appliances, and machines. Both tracks are growing lines inside a company whose center of gravity remains automotive and industrial silicon.
STM is tracked in Semiconductors, rated Growing on the AI Exposure leaderboard.

Frequently asked questions
What does STMicroelectronics do?
ST makes analog, power, sensing, and microcontroller chips for customers worldwide. Automotive and industrial markets generate most of its revenue, spanning silicon carbide devices for electric vehicles to the STM32 microcontroller family used across embedded electronics.
How is STMicroelectronics exposed to AI?
Supercycle rates ST as Growing with an AI Exposure Score of 40 out of 100. It supplies power conversion silicon for AI data centers and edge AI microcontrollers, but automotive and industrial chips dominate revenue, similar to peers like NXP and Texas Instruments.
What is the STM32N6?
The STM32N6 is ST's edge AI microcontroller, carrying a built-in neural accelerator that runs computer vision and other AI models directly on low-power devices. The ST Edge AI Suite provides the tools developers use to deploy models on it.
Who leads STMicroelectronics?
Jean-Marc Chery serves as president and chief executive. A veteran of the company's manufacturing and technology organizations, he has led ST through its silicon carbide expansion and its push into edge AI and data center power.
Is STM a pure play AI stock?
No. ST is a Growing tier stock. AI data center power and edge AI microcontrollers are genuine growth lines, but the company is a diversified European chipmaker whose results depend mainly on automotive and industrial demand cycles.
