Onsemi announced on June 25 that it has entered a definitive agreement to acquire Synaptics in an all-stock transaction valued at approximately $7 billion. Under the terms, Synaptics shareholders will receive 1.35 shares of onsemi common stock per Synaptics share, representing a roughly 19% premium. The deal, onsemi's largest to date, is expected to close in mid-2027 pending Synaptics shareholder approval and regulatory clearance.
Synaptics brings a differentiated Edge AI compute franchise centered on its Astra platform, which combines purpose-built AI processors, neural processing units (NPUs), multimodal intelligence, and an industry-leading wireless connectivity portfolio spanning Wi-Fi, Bluetooth, and GPS. Onsemi builds on strengths in power semiconductors, sensing, and automotive/industrial expertise. Together, the combined company aims to position itself at the intersection of the four pillars of Physical AI: power, sense, connected compute, and control.
The deal expands onsemi's total addressable market by $30 billion to $243 billion by 2030, with expected $200 million in annual synergies and EPS accretion within 18 months. Gross margins are expected to remain consistent with onsemi's long-term model. Architects planning edge AI and robotics stacks should monitor this consolidation—Synaptics' edge processors and connectivity become critical components in physical AI systems that sense and act in real-time across automotive, industrial IoT, and robotics use cases.
