ON Semiconductor Corporation (onsemi) said in a joint press release on June 25 that it agreed to acquire Synaptics Incorporated in an all-stock transaction, calling the combination a step toward next-generation intelligent systems and AI that interacts with the physical world.
Physical AI Strategy and Market Expansion
Onsemi described the acquisition as accelerating its shift from a power-and-sensing supplier to a leading provider of intelligent systems focused on Physical AI, which it defines as machines that sense, decide, act, and adapt in the physical world. Synaptics will add edge AI compute platforms, human-machine interface technology, audio and video processing, and connectivity to create an integrated "Power + Sense + Compute + Connect" stack for intelligent devices and systems.
The company said the deal expands its total addressable market by $30 billion to $243 billion by 2030. It targets growth across AI data centers, industrial automation, smart-home and IoT devices, and automotive systems such as infotainment and driver-monitoring. Management expects the combined portfolios to deepen customer engagements, especially with large original equipment manufacturers and cloud-edge customers.
Transaction Terms and Approvals
Onsemi and Synaptics signed a definitive all-stock agreement under which Synaptics shareholders will receive onsemi shares. Closing depends on Synaptics shareholder approval, customary regulatory clearances, and other standard conditions. Onsemi expects the transaction to be accretive to non-GAAP earnings per share in the second year after closing, driven by revenue synergies and cost efficiencies.
The acquisition, valued at approximately $7 billion on an enterprise-value basis, is onsemi’s largest to date and marks a significant strategic shift in its capital allocation. Both companies are listed on NASDAQ, and the all-stock structure will require issuance of new onsemi shares subject to regulatory filings. The press release did not specify an expected closing date or detailed terms such as the share exchange ratio or premium.
Regulatory approvals will likely include U.S. antitrust review and possibly other national competition authorities, given the transaction size and global footprint, though no specific agencies were named.
The deal positions onsemi to expand its offerings beyond power semiconductors and sensing into compute, human-machine interface, and connectivity capabilities at the edge, aiming to serve markets including AI data centers, industrial automation, smart home, IoT, and automotive applications.
