# ON Semiconductor: Business Model & Revenue Engine

## Direct Answer

ON Semiconductor reports revenue across 3 business segments in its fiscal 2025 Form 10-K. Power Solutions Group is the largest, with $2.8 billion of revenue (47% of the total), followed by Analog Mixed Signal Group at $2.3 billion (38%). 21% of revenue came from the United States.

## How Does ON Semiconductor Make Money?

No single line supplies a majority of revenue: the largest, Power Solutions Group, is 47%, which spreads ON Semiconductor's exposure across several demand drivers. Between fiscal 2024 and 2025, Analog Mixed Signal Group grew fastest (-13.3%) and Intelligent Sensing Group slowest (-17.5%), so the revenue mix tilts toward Analog Mixed Signal Group while that gap lasts.

| Segment | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
| --- | --- | --- | --- | --- |
| Power Solutions Group | $2.8 billion | $3.3 billion | 46.8% | -16.2% |
| Analog Mixed Signal Group | $2.3 billion | $2.6 billion | 37.7% | -13.3% |
| Intelligent Sensing Group | $928 million | $1.1 billion | 15.5% | -17.5% |

## Where Does ON Semiconductor's Revenue Come From?

Regions follow the definitions in the filing; most companies assign revenue by customer location.

| Region | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
| --- | --- | --- | --- | --- |
| Hong Kong | $1.6 billion | $1.8 billion | 27.3% | -8.1% |
| United Kingdom | $1.3 billion | $1.6 billion | 22.5% | -17.8% |

## What the Segment Figures Do Not Show

The rows above add up to 100% of ON Semiconductor's reported revenue for fiscal 2025; the difference is intersegment eliminations, corporate revenue or items the company reports outside its segments. Segment definitions are management's choice and change when a company reorganizes, in which case it restates prior years in the next filing, so a multi-year comparison should use the figures from a single filing. Revenue shows where sales come from, not where profit or cash is earned: a small segment can carry most of the margin.

## Where These Numbers Come From

Every figure on this page is a value ON Semiconductor reported in the segment note and revenue disclosures of its Form 10-K filed February 9, 2026 (accession 0001097864-26-000006), read from the SEC's Financial Statement Data Sets. The prior-year column is the comparative figure from that same filing, so it reflects any restatement for a change in segments. Category names are the company's own XBRL labels, lightly reformatted for reading.

Rows that only total other rows (for example a "Products" line beside the individual products) are left out so nothing is counted twice. This page is educational and describes reported history for fiscal 2025; it is not a forecast or a recommendation.
