ON Semiconductor to acquire Synaptics in $7B all-stock deal for Edge AI

What happened

ON Semiconductor announced the acquisition of Synaptics in an all-stock deal with an enterprise value of ~$7B. Synaptics shareholders will receive 1.350 ONsemi shares for each of their shares.

Context and impact

This is one of the largest consolidation moves in "physical AI" — edge inference for cars, robotics and IoT. It signals that traditional analog/power chip makers see edge AI as the next battleground, not just hyperscale GPUs. For Synaptics, it ends its run as a standalone company after a decade of stagnation.
