Onsemi is acquiring Synaptics in an all-stock deal valued at roughly $7 billion, betting that owning the full edge AI stack beats assembling it piecemeal.
The two companies announced the agreement Thursday. Under the terms, each Synaptics shareholder gets 1.35 Onsemi shares per share held — a roughly 19% premium based on the prior ten-day average — leaving Synaptics investors with about 12% of the combined company. The deal has unanimous board approval from both sides and is expected to close in mid-2027, pending shareholder votes and regulatory sign-off. Onsemi brings power management and sensors; Synaptics brings AI processors, neural processing units, wireless connectivity (Wi-Fi, Bluetooth, GPS), touch and biometric sensors, and an open-source software stack.
The timing tells the real story. Synaptics has been burning money since its revenue fell sharply from 2022 peaks, which likely explains why it agreed to a deal where its stockholders end up with just 12% of the acquirer — less leverage than a cash-strapped seller usually wants. Onsemi has stayed profitable through its own sales decline, giving it the balance sheet to absorb the deal and push toward what both CEOs are calling "physical AI": systems in robotics, automotive, and industrial settings that sense, decide, and act without a data center in the loop.
The strategic logic echoes AMD's 2006 ATI acquisition — bolt on a capability you lack rather than build it from scratch. Whether the combined company can execute across automotive, industrial, robotics, and consumer edge devices simultaneously is a different question entirely; that is a wide front to defend.
