STMicroelectronics (ST) has completed the acquisition of NXP Semiconductors' (NXP) MEMS (microelectromechanical systems) sensor business, expanding its portfolio of automotive safety and industrial sensors.

On February 12, ST announced the completion of its acquisition of NXP's MEMS sensor business. ST had previously announced the completion of the acquisition on February 2, 2026 (local time), stating that the transaction had completed closing procedures, including regulatory approvals.

This acquisition follows a transaction announced in July 2025. According to the disclosure at the time, the transaction is valued at up to $950 million in cash, with $900 million paid upfront and up to $50 million additional payments upon achievement of technical milestones.

ST disclosed that the MEMS business being acquired is expected to generate approximately $300 million in sales in 2024. It also said the acquired business is expected to contribute to earnings by generating "mid-$40 million" in sales in the first quarter of 2026.

NXP announced on its website that its MEMS sensor product portfolio has been officially transferred to ST as of February 2, 2026. Industry insiders believe that this acquisition will expand ST's product line and customer base in automotive safety (airbags, vehicle dynamics, etc.) and industrial sensor applications.
