AI power accelerates as Synaptics adds compute

01 Running thesis

Recovery meets new growth vectors

ON is gaining momentum after a hard cyclical downturn. Revenue reached $1.6 billion in Q2 2026, up 9% year over year. The Power Solutions Group led the charge again, and factory utilization improved to 83%, lifting sequential gross margins.

The brightest spot is the AI data center market. ON sells components that move electricity efficiently from the wall to the processing chips. Management upgraded its forecast and now expects this AI revenue to more than double in 2026, driving a 34% sequential surge in the company's non-core end markets. ON is also expanding its ambitions by agreeing to acquire Synaptics, aiming to bundle connected compute parts with its power solutions.

The bull case is compelling: AI data center revenue is accelerating, gross margins are structurally expanding as factories fill up, and the Synaptics deal opens new cross-selling opportunities across the mass market.

The bear case remains grounded in the core cyclical markets. Automotive demand is still uneven, with European seasonal weakness offsetting growth in China. Furthermore, integrating Synaptics introduces major execution risks just as the company finishes its own internal manufacturing overhaul. Finally, raw material costs are rising, which could compress margins if ON loses the ability to raise prices.

Aug 2026Q2 2026 earnings showed AI data center revenue is now expected to more than double in 2026. This helped drive a 9% year-over-year increase in total revenue to $1.6 billion.
Aug 2026ON announced an agreement to acquire Synaptics, adding connected compute capabilities. Management also noted rising raw material costs that will require surgical price increases.
May 2026Q1 2026 revenue rose 5% year over year to $1,513.3 million, showing the downturn is easing. Power Solutions Group led the rebound with 14% year-over-year growth.
May 2026Management said AI data center revenue grew more than 30% quarter over quarter and should double year over year in 2026. Non-GAAP gross margin also expanded to 38.5%.
Feb 2026The Q4 2025 call shifted the story from downturn control to early recovery. Management said automotive inventory digestion was largely behind the company and industrial had likely bottomed.
Feb 2026The 2025 Form 10-K showed how deep the trough was: revenue fell 15.3% and gross margin dropped to 33.1%. It also added risks around AI market share and China operations.
Nov 2025The Q3 2025 call showed stabilization in auto and industrial demand, plus almost $250 million of expected 2025 AI revenue. Vcore Power and vGaN added to the AI power roadmap.
Nov 2025The Q3 2025 Form 10-Q still showed a deep downturn, with revenue down 12% year over year. All three segments declined by double digits.
02 Business model

Chips for power-hungry systems

ON designs and makes chips that control power, sense images, and improve energy use. It sells into cars, industrial equipment, solar systems, fast chargers, and AI data centers. The company earns money when customers build more electric vehicles, automate factories, or add power-heavy servers.

Power chips are the center of the model. They help convert, move, and manage electricity. That matters deeply in electric vehicles and AI servers, where wasted power becomes heat and excess cost.

The weak point is fixed manufacturing cost. Chip factories are expensive, so margins fall when demand drops and plants run below normal levels. ON has been cutting jobs and closing older facilities to match capacity with long-term demand. As utilization rises back to 83%, margins are expanding.

The strategy works if ON keeps winning higher-value designs and successfully absorbs Synaptics to add computing power to its offerings. It breaks if auto and industrial customers delay orders, if AI competition gets tougher, or if inflation outpaces the company's pricing power.

03 Product portfolio

Power first, sensing second

Cash cow

Automotive power chips

These chips manage power in vehicles, including electric vehicles and charging systems. This business is tied to EV adoption and general car production cycles.

Steady

Industrial and energy power

ON sells power parts for factory automation, solar, and industrial equipment. Demand can be lumpy because customers often cut orders when the economy slows.

Growth engine

AI data center power

ON provides power management parts for AI servers. Management expects this revenue to more than double year over year in 2026.

Growth engine

Silicon carbide and SiC JFETs

Silicon carbide helps systems run at higher power and efficiency. ON is seeing strong traction with these products in AI server power supply units.

Steady

Image and depth sensors

These sensors help cars and machines see their surroundings. The industrial image sensor design win funnel is growing steadily.

Option

Connected Compute (Pending)

The pending acquisition of Synaptics will add processing and connectivity chips to complement the existing power and sensing hardware.

Segment shares are based on Q2 2026 revenue of $1.6 billion. The Power Solutions Group is the largest segment and grew fastest.

05 Risk factors

What could go wrong

Synaptics integration fails

High impact · Medium odds

ON agreed to acquire Synaptics in mid-2026. The merger introduces major execution risks. If the companies fail to combine smoothly, ON could miss its synergy targets and distract management from the core power business.

We watchWatch for regulatory approvals, target closing dates, and management comments on overlapping sales teams.

Auto and industrial orders stall

High impact · Medium odds

ON relies heavily on automotive and industrial customers. Q2 2026 automotive revenue fell sequentially due to European weakness. If core market customers delay their restocking cycle, total revenue growth could stall.

We watchWatch automotive revenue growth, industrial order trends, and book-to-bill ratios.

Inflation compresses margins

Medium impact · High odds

Management noted in Q2 2026 that raw material and external manufacturing costs are rising. ON is implementing a second round of price increases to offset these costs. If customers reject the higher prices, profit margins will shrink.

We watchWatch sequential gross margin and management commentary on pricing power and input costs.

China and trade disruption

Medium impact · Medium odds

ON operates assembly and test facilities in Leshan, China. Actions by U.S. or Chinese governments could impact the market for ON's products. New trade restrictions could raise costs or block shipments entirely.

We watchWatch U.S. and China trade rules, restricted entity list changes, and any direct impacts on the Leshan plant.

Competition in AI power chips

Medium impact · High odds

AI power is highly attractive, drawing intense competition. ON must keep spending heavily on research and development to defend its share against established semiconductor rivals in the server market.

We watchWatch design wins, product launches in multiphase controllers, and any pricing pressure in the data center segment.
06 Quick answers

In one breath

What does ON Semiconductor make?

ON makes power and sensing chips. Its products help electric vehicles, chargers, factories, solar systems, and AI servers manage electricity and sense the world around them.

Why does AI matter for ON Semiconductor?

AI servers use a massive amount of power, and that power must be converted and controlled efficiently. ON sells power solutions for that job, and management expects AI data center revenue to more than double in 2026.

Is ON Semiconductor mainly an auto chip company?

Automotive is still a major market, but ON also sells into industrial, energy, and AI data center markets. The pending Synaptics acquisition will also bring new connected compute customers.

What should investors watch next?

The key signals are the closing progress of the Synaptics deal, sequential gross margin gains, and whether the company can successfully raise prices to cover rising raw material costs.
