onsemi

onsemi (ON Semiconductor) makes power and sensing chips. Its Power Solutions Group (PSG) sells silicon and silicon carbide power devices that convert and control electricity in cars, factories, solar and storage systems and AI data centers. Its Analog and Mixed-Signal Group (AMG) sells power management and control chips, and its Intelligent Sensing Group (ISG) sells image sensors, mainly for car cameras and industrial uses.

Cars and industrial customers give most of its revenue, and AI data centers are its fastest-growing market. onsemi makes most of its chips in its own factories. Revenue was $1.60 billion in Q2 2026, and PSG gave 52% of it. In June 2026, onsemi agreed to buy Synaptics, which makes connectivity, edge AI and sensing chips.

The market doubts that onsemi can return to steady growth. Its revenue fell in 2024 and 2025 because car makers sold fewer electric vehicles than planned and industrial customers used up their stock, and silicon carbide prices fell as Chinese suppliers added capacity. Investors also ask whether onsemi pays too much for Synaptics, a new market for the company, with new debt. For the gap to close, three things must be true.

Revenue must keep growing from a year earlier after the 9% rise of Q2 2026, and the non-GAAP gross margin must reach the 40% to 42% range of the Q3 guidance. AI data center revenue must more than double in 2026, as management now expects. The Synaptics purchase, now $5.7 billion in cash, must close by mid-2027 and add to non-GAAP earnings per share from the first quarter, as onsemi says it will. The Q3 report on November 2, 2026, gives the next test, the Synaptics shareholder vote and foreign approvals follow, and the deal should close by mid-2027.

If growth holds, the gap can close over the next four to six quarters. A new fall in car demand or a longer silicon carbide price war can delay it.

onsemi funds itself mostly with low-cost convertible notes and one issue of senior notes. On July 3, 2026, it had $3.5 billion of cash and $350 million of short-term investments. Read more

• Car makers give a large part of revenue. If sales of electric and hybrid vehicles slow again, or car makers cut chip stock, demand for silicon carbide and other power chips can fall.
• Chinese suppliers add silicon carbide capacity and cut prices. This can reduce onsemi's prices and gross margin, and it can leave its own factories underused.
• The $5.7 billion cash purchase of Synaptics brings new markets and new debt. The deal still needs a Synaptics shareholder vote and foreign approvals, and the integration or the planned $200 million of cost synergies can take longer than planned.
• AI data center revenue grows fast but is still a small part of sales. Competition from other power chip makers is strong, and customers can change suppliers between product generations.

• October 15, 2026onsemi said that it will report its Q3 2026 results after the market closes on November 2, 2026.
• October 1, 2026onsemi and Synaptics changed their merger agreement after Synaptics received an unsolicited offer from another company. onsemi will now pay $123 per Synaptics share in cash, about $5.7 billion, in place of the June all-stock deal worth about $7 billion. onsemi now expects the deal to add to non-GAAP EPS at once. Morgan Stanley committed up to $2.45 billion of secured term loans. The US Federal Trade Commission approved the deal, and onsemi still expects it to close by mid-2027.
• September 16, 2026onsemi held an investor day. It said that it addresses a market of $213 billion by 2030 across cars, industry and AI data centers. It also launched an Embedded Power Platform for AI data centers, and Subaru agreed to evaluate it for future electric vehicles.
