onsemi and Synaptics Incorporated have finalized a definitive merger agreement under which onsemi will acquire Synaptics in an all-stock transaction. The mega-merger has been set at the level of $7 billion of total enterprise value.
In accordance with the conditions of the merger agreement, Synaptics stockholders will get a certain exchange ratio of 1.350 shares of onsemi common stock for each share of Synaptics. The exchange ratio is set at an approximate 19% premium to the 10-day volume weighted average closing price of both stocks.
The corporate consolidation is designed to accelerate onsemi’s transition toward global leadership in comprehensive intelligent systems. Integrating Synaptics’ high-margin Edge AI compute franchise alongside its deep human-machine interface (HMI) and wireless connectivity portfolio allows onsemi to extend its structural reach beyond foundational power and sensing hardware.
The combined platform will build directly upon onsemi’s established presence across the automotive, industrial, and AI data center sectors. Ultimately, the transaction establishes onsemi as a centralized provider of “Physical AI”-expanding the company’s total addressable market (TAM) by an estimated $30 billion to reach $243 billion by 2030.

“As artificial intelligence moves beyond the cloud and into the physical world, including automotive and industrial, the next phase of innovation will depend on systems that can sense, decide, act and adapt in real time,” said Hassane El-Khoury, President and CEO of onsemi. “This shift towards Physical AI will require Power, Sense, Connected Compute and Control to work together seamlessly. The addition of Synaptics helps position onsemi at the intersection of these four pillars, enabling us to capture a significantly larger AI opportunity that extends beyond AI data center and into edge applications. This transaction would add immediate connected compute capabilities, expand our software and ecosystem reach and position onsemi to deliver greater value as customers increasingly seek intelligent systems.”
“Today’s announcement marks an important step in accelerating Synaptics’ growth and leadership in Edge AI and Physical AI,” said Rahul Patel, Synaptics President and CEO. “Together with onsemi, we will combine Synaptics’ strengths in AI-native compute, connectivity, and human-machine interface with onsemi’s leadership in intelligent power and sensing to offer customers integrated solutions and development platforms across every layer of the Edge AI stack, deepening customer engagement and expanding across a greater total addressable market. The all-stock structure allows our shareholders to participate in the compelling growth and value creation opportunities ahead, and I look forward to working with the onsemi leadership team to help realize the full value of this combination.”
Key Strategic and Financial Drivers
The merger outlines several distinct commercial advantages for the unified organization:
Bridging AI Infrastructure with Physical AI: While onsemi holds a strong position across baseline AI infrastructure-ranging from power grid applications to core data center power management-this transaction extends its capabilities to the intelligent edge. The unified entity will deliver comprehensive, system-level solutions across the four core pillars: Power, Sense, Connected Compute, and Control. This architecture supports real-time operational processing required for autonomous driving systems, advanced robotics, and next-generation AR/VR hardware.
Integration of a Scalable Edge AI Compute Network: The acquisition adds Synaptics’ proprietary Astra™ platform to onsemi’s technical stack. Astra combines custom AI processors and Neural Processing Units (NPUs) built for multimodal intelligence with a mature wireless connectivity suite (spanning Wi-Fi, Bluetooth, and GPS) alongside an open-source software layer built for fast market deployment.
Synergistic Portfolios Targeting Revenue Scale: The alignment of these highly complementary product lines allows onsemi to accelerate its long-term engineering roadmap, capture higher dollar content per client platform, and build deeper enterprise customer retention. The increased exposure to high-value system solutions featuring embedded IP and proprietary software is projected to drive gross margin expansion, shift product mix favorably, and secure resilient growth.
Favorable Financial Architecture: Financially, the transaction is projected to be accretive to onsemi’s non-GAAP earnings per share (EPS) within 18 months following the close of the deal. The companies anticipate realizing approximately $200 million in annualized run-rate cost synergies. Additionally, target gross margins are projected to remain fully aligned with onsemi’s long-term financial operating model. During the pendency period of the acquisition, onsemi remains committed to its established capital return framework.
