ON Semiconductor (ON) shares took a hit Friday after the company announced a definitive agreement to acquire Synaptics Incorporated (SYNA) in an all-stock deal valued at roughly $7 billion. The market's reaction was swift: ON shares dropped 13.6% to $102.59 in premarket trading, while Synaptics shares jumped 4.68% to $131.50.
Under the terms, Synaptics shareholders will receive 1.350 ON Semiconductor shares for each Synaptics share they own. That represents a roughly 19% premium based on the companies' 10-day volume-weighted average closing prices. Synaptics shareholders are expected to own about 12% of the combined company on a fully diluted basis, and one Synaptics director is expected to join ON Semiconductor's board.
ON Semiconductor Targets Physical AI Growth
The acquisition is designed to strengthen ON Semiconductor's intelligent systems portfolio by combining its power and sensing technologies with Synaptics' Edge AI computing, wireless connectivity, and human-machine interface solutions. The companies say the deal will expand ON Semiconductor's total addressable market by $30 billion to $243 billion by 2030.
CEO Hassane El-Khoury said the acquisition positions ON Semiconductor to benefit from the growing Physical AI market by combining power, sensing, compute, and control technologies. He added that Synaptics also expands the company's software capabilities and strengthens its edge AI portfolio.
Synaptics President and CEO Rahul Patel said the combination brings together complementary technologies to deliver integrated Edge AI platforms. He noted that the all-stock transaction allows Synaptics shareholders to participate in the combined company's future growth.
Synergies, Financial Impact, and Closing Timeline
The combined company expects to provide integrated solutions for autonomous vehicles, robotics, and augmented and virtual reality applications. Synaptics' Astra platform adds AI processors, neural processing units, wireless connectivity, and an open-source software stack to ON Semiconductor's product portfolio.
The companies expect the transaction to be accretive to non-GAAP earnings per share within 18 months of closing. They also expect about $200 million in annual synergies. The acquisition is expected to close in mid-2027, subject to Synaptics shareholder approval, regulatory clearances, and customary closing conditions.
Both companies reaffirmed their previously issued financial outlooks. Morgan Stanley advised ON Semiconductor, while Qatalyst Partners served as financial advisor to Synaptics.
For now, investors seem to be pricing in some skepticism about the deal's near-term benefits, as ON shares fell sharply. But the long-term thesis—combining ON's power and sensing with Synaptics' edge AI—could pay off if the Physical AI market takes off as expected.
