STMicroelectronics, a global semiconductor provider of electronics applications, announces a planned acquisition of NXP Semiconductors’ MEMS sensors business, focused on automotive safety products and sensors for industrial applications. The transaction will complement ST’s MEMS sensors technology and product portfolio, for development across automotive, industrial and consumer applications.

“The planned acquisition is a great strategic fit for ST,” says Marco Cassis, president, Analog, Power & Discrete, MEMS and Sensors Group of STMicroelectronics. “Together with ST’s existing MEMS portfolio, these highly complementary technologies and customer relationships, focused on automotive safety and industrial technologies, will strengthen our position in sensors across key segments in automotive, industrial and consumer applications.”

“NXP is a leading supplier of automotive MEMS based motion and pressure sensors, with a long history of strong customer adoption,” says Jens Hinrichsen, executive vice president and general manager, Analog and Automotive Embedded Systems of NXP. “However, after careful portfolio review the company has decided the business does not fit into its long-term strategic direction. We have agreed with STMicroelectronics that the product line will fit ideally into ST’s portfolio, manufacturing footprint and strategic roadmap.”

The MEMS sensors portfolio to be acquired by ST primarily targets automotive safety sensors, both passive (airbags) and active (vehicle dynamics), as well as monitoring sensors. It also includes pressure sensors and accelerometers for industrial applications. MEMS technologies enable advanced functionalities for safety, electrification, automation, and connected vehicles.

MEMS inertial sensors in automotive are expected to grow at a fast. The business to be acquired generated about $300 million revenues in 2024 with gross and operating margin accretive for ST. It is also expected to be accretive to ST earnings per share from completion.

The planned acquisition will enhance ST’s MEMS technology, product R&D capabilities and roadmap, with IP, technology and products for automotive safety applications and R&D teams. The expanded business will uee ST’s integrated device manufacturer model for MEMS, which involves every stage of MEMS development, from design and manufacturing to testing and packaging.

STMicroelectronics and NXP have entered into a definitive transaction agreement for a purchase price of up to US$950 million in cash, including US$900 million upfront and US$50 million subject to the achievement of technical milestones. The transaction, which will be financed with existing liquidity, is subject to customary closing conditions, including regulatory approvals, and is expected to close in H1 2026.
