STMicroelectronics to Acquire NXP’s MEMS Sensors Business for Up to $950M
Published: 8.8.2025
STMicroelectronics has entered into an agreement to acquire NXP Semiconductors’ MEMS sensor unit for up to US $950 million in cash, with an initial $900 million upfront and another $50 million tied to milestone achievements.
The business generated approximately $300 million in 2024 revenue, with margins that are expected to be accretive to ST’s earnings per share upon closing, anticipated in H1 2026, subject to regulatory approvals.
NXP’s MEMS portfolio—covering automotive safety sensors (airbags, vehicle dynamics), TPMS, engine monitoring, pressure sensors, and accelerometers for industrial applications—aligns tightly with ST’s existing roadmap.
The acquisition injects both IP and high-growth customer relationships into ST’s integrated device manufacturer (IDM) model, streamlining R&D through manufacturing to packaging.
“The planned acquisition is a great strategic fit for ST,” said Marco Cassis, President of ST’s MEMS and Sensors Group. “These highly complementary technologies and customer relationships… will strengthen our position in sensors across key segments.”
Echoing the view from NXP’s side, Jens Hinrichsen, EVP at NXP, stated the portfolio “no longer aligns with our long-term strategic direction” and that ST offers a more suitable home for the MEMS team.
Despite softness in broader semiconductor demand, the MEMS segment remains resilient—with 2024 global shipments around $14.6 billion and projected growth to $20 billion by 2029. Automotive inertial sensors, specifically, are outpacing broader MEMS markets thanks to increasing EV and ADAS penetration.
“Within this overall market, inertial sensors in automotive are expected to grow faster,” noted Simone Ferri, VP of ST’s MEMS division. “Motor vehicle electrification, automation, and safety applications drive this momentum.”
Implications for Industry Stakeholders
Automotive OEMs & Tier 1 suppliers: Expect increased access to safety-critical and next-gen MEMS sensors from a unified ST ecosystem
Industrial and consumer electronics integrators: Potential to source broader sensor modules integrated with ST’s microcontroller and power solutions
Investors and analysts: Opportunity to gain from ST’s strategic positioning in a high-growth, resilient sensor segment
This high-profile acquisition positions STMicroelectronics as a dominant player in safety-critical MEMS, blending innovation, scale, and client relationships. As MEMS sensors become increasingly vital in automotive electrification and automation, this deal could shape sensor roadmaps for years ahead.
