onsemi to Acquire Edge AI Chip Company Synaptics in $7 Billion All-Stock Deal

onsemi (安森美) announced on June 25 that it will acquire edge AI chip company Synaptics in an all-stock transaction valued at approximately $7 billion (approximately 47.66 billion yuan). The deal is expected to close by mid-2027.

Under the terms of the agreement, Synaptics shareholders will hold approximately 12% of onsemi on a fully diluted basis following the completion of the transaction. As part of the deal, one member of Synaptics’ board of directors is expected to join onsemi’s board.

onsemi stated that the two companies possess highly complementary product portfolios, with Synaptics providing a mature edge AI connectivity and computing platform. The acquisition is expected to extend onsemi’s business scope from AI infrastructure into the intelligent edge, opening up more end markets in the realm of physical AI — where AI systems interact directly with the physical world.

On the financial front, onsemi expects the deal to be accretive to non-GAAP earnings per share within 18 months of closing. The company anticipates approximately $200 million in annual cost synergies, with gross margins expected to align with onsemi’s long-term semiconductor financial model.

The acquisition marks a significant consolidation play in the semiconductor industry, combining onsemi’s strength in power management, sensing, and analog solutions with Synaptics’ expertise in edge AI processing and connectivity. As AI workloads increasingly move from cloud data centers to edge devices — from autonomous vehicles and industrial robots to smart sensors — the combined entity aims to capture a broader slice of the growing edge AI chip market.
