STMicroelectronics, a global leader in semiconductors serving a broad range of electronics markets, has announced a definitive agreement to acquire the MEMS sensors business of NXP Semiconductors. The acquisition will significantly strengthen ST’s position in the global MEMS market, particularly in the fast-growing segments of automotive safety and industrial sensing.
NXP’s MEMS portfolio, highly regarded for its motion and pressure sensors, is widely used in automotive safety applications such as airbags and vehicle dynamics, as well as in tire pressure monitoring, engine management, and security systems. The acquisition also includes sensors for industrial use cases.
“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. By leveraging our IDM model, with technology R&D, product design and advanced manufacturing, we will better serve all our customers worldwide.”
“NXP is a leading supplier of automotive MEMS based motion and pressure sensors, with a long history of strong customer adoption,” said 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. We are gratified that the MEMS sensor team will have an excellent home and long-term future at ST.”
The MEMS sensor portfolio STMicroelectronics is acquiring from NXP is centered on automotive safety applications, including both passive systems (such as airbags) and active systems (like vehicle dynamics control). It also includes monitoring sensors used in tire pressure monitoring systems (TPMS), engine management, vehicle security, and driver convenience features. Beyond automotive, the portfolio encompasses industrial-grade pressure sensors and accelerometers.
ST is positioned to leverage this expanded portfolio through its strong, established relationships with Tier 1 automotive suppliers and its innovation roadmap tailored to the fast-evolving MEMS automotive market. As MEMS technologies become increasingly critical to enabling vehicle safety, electrification, automation, and connectivity, this acquisition is expected to significantly bolster ST’s market position and revenue potential.
Notably, MEMS inertial sensors in automotive are forecasted to outpace the growth of the broader MEMS market. The business ST is acquiring generated approximately $300 million in revenue in 2024 and is expected to be immediately accretive to ST’s gross margin, operating margin, and earnings per share (EPS) post-completion.
The acquisition will enhance ST’s MEMS technology capabilities, product development roadmap, and intellectual property portfolio, particularly in automotive safety systems. It also brings in highly specialized R&D talent. The acquired business will integrate into ST’s Integrated Device Manufacturer (IDM) model, which spans the entire MEMS value chain from design and fabrication to testing and packaging, enabling faster innovation cycles and more flexible customization.
STMicroelectronics and NXP have entered into a definitive transaction agreement valued at up to $950 million in cash, with $900 million paid upfront and $50 million contingent upon the achievement of specific technical milestones. The transaction, funded through existing liquidity, is subject to customary regulatory approvals and is expected to close in the first half of 2026.
