Onsemi acquires Synaptics for $7B to consolidate Edge AI and Physical AI stack
Onsemi agreed to acquire Synaptics in an all-stock transaction valued at approximately $7 billion on June 25, 2026, combining the chipmaker's power and sensing expertise with Synaptics' Edge AI compute platform and human-machine interface capabilities. The deal, structured at 1.35 onsemi shares per Synaptics share, represents a roughly 19% premium and would give Synaptics shareholders about 12% ownership of the combined company on a fully diluted basis.
The acquisition targets what Onsemi terms the four pillars of Physical AI: power, sensing, connected compute, and control. Synaptics brings its Astra platform—combining AI processors, neural processing units, wireless connectivity (Wi-Fi, Bluetooth, GPS), and open-source software—to complement onsemi's automotive and industrial sensor footprint. Onsemi expects $200 million in annual synergies and projects the deal to be accretive to non-GAAP earnings per share within 18 months of closing.
By expanding onsemi's total addressable market by $30 billion to $243 billion by 2030, the combination aims to capture higher-margin system-level solutions across automotive, robotics, and industrial IoT rather than standalone components. For architects, this signals chipmakers' shift toward full-stack edge AI platforms, bundling inference, connectivity, and real-world sensing. The deal closes mid-2027, subject to shareholder and regulatory approvals.
