Onsemi acquires Synaptics for $7 billion, betting on physical AI and robotics markets.
onsemi is making its biggest strategic move yet, agreeing to acquire Synaptics Incorporated in an all-stock deal valued at roughly $7 billion. The acquisition strengthens onsemi's transformation from a power and sensing specialist into a provider of intelligent, system-level solutions for the emerging Physical AI market.
The transaction adds Synaptics' Edge AI compute platform, wireless connectivity technologies and human-machine interface portfolio to onsemi's leadership in power semiconductors and sensing. Together, the companies aim to deliver integrated solutions spanning power, sensing, connected compute and control for autonomous vehicles, robotics, industrial automation and AR/VR applications. Management believes the combination could expand onsemi's total addressable market by $30 billion to $243 billion by 2030.
The deal aligns with the strategy outlined during onsemi's first-quarter 2026 earnings call, where management highlighted accelerating AI data center demand, growing adoption of its Treo intelligent mixed-signal platform and increasing traction in software-defined vehicles and industrial automation. Executives emphasized that the company already possessed the technologies to capitalize on AI infrastructure and had remained focused on targeted acquisitions to broaden its technology portfolio.
Financially, the acquisition is expected to become accretive to non-GAAP earnings within 18 months after closing, while generating approximately $200 million in annual cost synergies. Synaptics shareholders will own about 12% of the combined company, with the transaction expected to close in mid-2027, pending shareholder and regulatory approvals. If successfully integrated, the acquisition could position onsemi as one of the industry's most comprehensive Physical AI semiconductor platforms, extending well beyond its traditional power semiconductor franchise.
onsemi expects its AI data center revenues to double in 2026, supported by growing adoption across hyperscalers and the entire power delivery chain, while its silicon carbide, GaN and Treo mixed-signal platforms are gaining traction in automotive, industrial automation and robotics. This aggressive acquisition strategy and integrated system-level approach contrasts with competitors: STMicroelectronics continues leveraging its strengths in silicon carbide, industrial automation and automotive semiconductors, but remains more exposed to cyclical automotive weakness. Texas Instruments, meanwhile, benefits from its broad analog and embedded processing portfolio and strong industrial customer base, but has largely relied on organic innovation rather than transformational acquisitions.
Shares of the Arizona-based semiconductor company have surged 103.5% in the past three months. onsemi stock currently trades at a forward 12-month price-to-earnings ratio of 32.06, a discount compared with industry peers. Earnings estimates for 2026 and 2027 have moved upward to $3.09 and $4.36 per share respectively, implying year-over-year growth of 31.5% and 41.1%.
