# Teradyne: Business Model & Revenue Engine

## Direct Answer

Teradyne reports revenue across 3 business segments in its fiscal 2025 Form 10-K. Semiconductor Test is the largest, with $2.5 billion of revenue (79% of the total), followed by Product Test at $358 million (11%).

## How Does Teradyne Make Money?

Semiconductor Test supplies 79% of revenue, so Teradyne's results move mostly with that one business; the others matter more for diversification than for the headline number. Between fiscal 2024 and 2025, Semiconductor Test grew fastest (+18.8%) and Robotics slowest (-15.5%), so the revenue mix tilts toward Semiconductor Test while that gap lasts.

| Segment | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
| --- | --- | --- | --- | --- |
| Semiconductor Test | $2.5 billion | $2.1 billion | 79.1% | 18.8% |
| Product Test | $358 million | $331 million | 11.2% | 8.1% |
| Robotics | $308 million | $365 million | 9.7% | -15.5% |

## What Does Teradyne Sell?

Teradyne also breaks revenue down by product and service line, which shows what customers pay for rather than how management organizes the business.

| Product or service | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
| --- | --- | --- | --- | --- |
| Product | $2.7 billion | $2.3 billion | 83.4% | 15.9% |
| Service | $530 million | $525 million | 16.6% | 0.9% |

## What the Segment Figures Do Not Show

The rows above add up to 100% of Teradyne'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 Teradyne reported in the segment note and revenue disclosures of its Form 10-K filed February 19, 2026 (accession 0001193125-26-059002), 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.
