onsemi (formerly ON Semiconductor): Company overview
| Brand | onsemi |
|---|---|
| Legal name | ON Semiconductor Corporation |
| Headquarters | Scottsdale, Arizona, United States |
| Founded | 1999 |
| President and CEO | Hassane El-Khoury |
| Employees | Approximately 26,000 |
| Stock exchange | Nasdaq |
| Ticker | ON |
| 2025 revenue | Approximately $6.0 billion |
| Priority markets | Automotive, industrial, AI data centers, and others |
onsemi was established in 1999 as a spin-off from Motorola’s semiconductor operations. It subsequently expanded its analog, power semiconductor, and sensor businesses through transactions involving Sanyo Semiconductor, Fairchild Semiconductor, and GT Advanced Technologies, among others.
Why ON Semiconductor became onsemi
The 2021 rebranding clarified the company’s transformation from a broad semiconductor supplier into a provider of intelligent power and sensing technologies for vehicle electrification, advanced safety, renewable energy, and factory automation.

Three business groups
| Business group | Main products | Q1 2026 revenue |
|---|---|---|
| Power Solutions Group (PSG) | SiC, IGBTs, MOSFETs, diodes, and power modules | $736.6 million |
| Analog and Mixed-Signal Group (AMG) | Analog ICs, power management, interfaces, and motor control | $540.4 million |
| Intelligent Sensing Group (ISG) | CMOS image sensors and automotive and industrial sensing | $236.3 million |
The Advanced Solutions Group name used in older reports has been replaced by Analog and Mixed-Signal Group in current disclosures. In the first quarter of 2026, PSG revenue increased 14% year over year and led company growth.
Automotive is the largest end market
In 2025, automotive generated 51% of revenue, industrial generated 28%, and other markets—including AI data centers and computing—generated 21%. Automotive and industrial together accounted for almost 80%.
- Electrification: EV traction inverters, onboard chargers, and DC-DC converters
- Advanced safety: ADAS image sensors and automotive cameras
- In-vehicle networking: Ethernet products for zonal architectures
- Industrial: Motor control, robotics, renewable energy, and energy storage
- AI data centers: Power conversion, 48 V and high-voltage power delivery, and SiC JFETs
In the first quarter of 2026, AI data-center revenue more than doubled year over year and grew more than 30% sequentially. While automotive and industrial remain the core markets, onsemi is positioning power efficiency for AI infrastructure as a new growth driver.
EliteSiC supports higher-voltage EV platforms
Silicon carbide is a wide-bandgap semiconductor suited to higher voltages, higher operating temperatures, and faster switching than conventional silicon. Lower power-conversion losses can extend EV driving range, shorten charging times, and reduce cooling-system size.
- EliteSiC MOSFETs: EV traction inverters, fast charging, and renewable energy
- SiC diodes: High-efficiency power conversion
- SiC JFETs: AI data-center power supplies, EV battery disconnects, and industrial circuit breakers
- Voltage platforms: Expanding from 400 V to 800 V and 900 V vehicle architectures
In 2026, onsemi expanded its collaboration with NIO to use EliteSiC in 900 V EV platforms. The higher-voltage architecture is intended to improve charging speed and power efficiency.
Vertically integrated SiC manufacturing
onsemi emphasizes vertical integration from SiC materials through devices and modules. It acquired SiC crystal technology company GT Advanced Technologies in 2021 and purchased Qorvo’s SiC JFET technology business for $115 million in 2025.
| Location | Main role |
|---|---|
| Hudson, New Hampshire, USA | SiC materials and technology |
| Bucheon, South Korea | SiC power semiconductors, IGBTs, and analog products |
| East Fishkill, New York, USA | 300 mm wafer manufacturing and image sensors |
| Gresham, Oregon, USA | Automated wafer fabrication |
| Aizu, Japan | Power and analog semiconductor wafer manufacturing |
The company operates 19 manufacturing sites in nine countries. In the volatile SiC market, vertical integration can improve supply stability and lower costs, but factory utilization and returns on capital remain important challenges.
Latest results for the first quarter of 2026
| Metric | Q1 2026 |
|---|---|
| Revenue | $1.5133 billion |
| GAAP gross margin | 38.5% |
| GAAP operating margin | -3.5% |
| Non-GAAP operating margin | 19.1% |
| GAAP net loss | $33.4 million |
| Non-GAAP net income | $253.1 million |
Revenue increased by approximately 5% year over year. Special items contributed to a GAAP operating loss and net loss, while the non-GAAP operating margin was 19.1%. Management said demand had moved beyond its cyclical trough and was on a recovery path.
The proposed Synaptics acquisition has not closed
On June 25, 2026, onsemi announced a definitive agreement to acquire Synaptics in an all-stock transaction with an enterprise value of approximately $7 billion. The transaction is expected to close in mid-2027.
As of July 14, 2026, the acquisition has not been completed. It remains subject to approval by Synaptics stockholders, regulatory clearances, and other customary conditions. If completed, Synaptics would add edge-AI computing, wireless connectivity, and human-machine interface technologies to onsemi’s power and sensing portfolio.
