onsemi announced an agreement to acquire Synaptics in an all-stock transaction with an implied value of approximately $7 billion. Under the terms, each Synaptics share will be exchanged for 1.35 shares of onsemi common stock, a swap that the companies say equates to about a 19% premium relative to the combined 10-day volume-weighted average share prices. On a fully diluted basis, Synaptics shareholders would own roughly 12% of the combined entity.
The deal is being presented as a strategic move to broaden onsemi's footprint beyond its existing strength in power management and sensing, and to assemble an integrated technology stack for what the companies describe as "Physical AI" - AI-driven systems that operate in the real world at the edge rather than inside data centers.
Synaptics brings Edge AI compute, wireless connectivity and human-machine interface technologies to the table. The transaction is expected to allow the combined company to offer tighter integration across power, sensing, connected computing and control, targeting applications such as autonomous vehicles, robotics and augmented and virtual reality.
Synaptics' Astra platform is highlighted as a key complementary asset. The platform combines AI processors, neural processing units, wireless connectivity technologies and open-source software tools, and is expected by onsemi to bolster its capabilities for edge AI workloads.
onsemi's chief executive said the acquisition will help accelerate the company's transition from a supplier of power and sensing components to a broader intelligent systems platform. The company framed the move as a way to capitalize on AI opportunities that extend beyond data centers and into edge devices that interact with the physical world.
Financially, onsemi projected that the transaction would expand its total addressable market by $30 billion, bringing the combined TAM to $243 billion by 2030. The company also said it expects the deal to be accretive to non-GAAP earnings per share within 18 months after closing and to generate approximately $200 million in annual synergies. Gross margins are expected to remain aligned with onsemi's long-term financial model.
The boards of both companies have unanimously approved the agreement. The companies said the transaction remains subject to customary closing conditions, including Synaptics shareholder approval and regulatory clearances, and is targeted to close in mid-2027. Both firms reiterated the financial outlooks they previously issued for their current fiscal quarters.
Market reaction was swift for Synaptics shares, which rose by more than 10% in extended trading after the announcement.
Context and implications
The combination pairs onsemi's established business in power management and sensing with Synaptics' edge computing and interface technologies, creating a proposition the companies say will span hardware and software elements needed for intelligent systems that operate outside data centers. The stated target markets - autonomous vehicles, robotics and AR/VR - are areas where integrated power, sensing and compute can be crucial to product performance at the edge.
From a financial standpoint, onsemi's estimates for near-term accretion and the $200 million in synergies set specific expectations for the deal's contribution to profitability, while the TAM expansion figure frames the long-term market opportunity the company is pursuing.
Yet the transaction remains contingent on shareholder and regulatory approvals and other customary conditions before it can be completed.
