Direct Answer
Teledyne Technologies reports revenue across 4 business segments in its fiscal 2025 Form 10-K. Digital Imaging is the largest, with $3.2 billion of revenue (52% of the total), followed by Instrumentation at $1.5 billion (24%). 52% of revenue came from the United States.
How Does Teledyne Technologies Make Money?
No single line supplies a majority of revenue: the largest, Digital Imaging, is 52%, which spreads Teledyne Technologies's exposure across several demand drivers. Between fiscal 2024 and 2025, Aerospace and Defense Electronics grew fastest (+36.3%) and Engineered Systems slowest (-0.9%), so the revenue mix tilts toward Aerospace and Defense Electronics while that gap lasts.
| Segment | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
|---|---|---|---|---|
| Digital Imaging | $3.2 billion | $3.1 billion | 51.7% | 3.0% |
| Instrumentation | $1.5 billion | $1.4 billion | 23.8% | 5.4% |
| Aerospace and Defense Electronics | $1.1 billion | $777 million | 17.3% | 36.3% |
| Engineered Systems | $436 million | $440 million | 7.1% | -0.9% |
Which Teledyne Technologies Segments Earn the Most?
| Segment | FY2025 segment operating income | Segment margin |
|---|---|---|
| Digital Imaging | $528 million | 16.7% |
| Instrumentation | $400 million | 27.5% |
| Aerospace and Defense Electronics | $262 million | 24.8% |
| Engineered Systems | $47 million | 10.7% |
Segment operating income is the profit measure Teledyne Technologies reports to its chief operating decision maker for each segment. It usually leaves out corporate costs that are not allocated to a segment, so the segments usually add up to more than consolidated operating income, and margins are comparable within Teledyne Technologies more safely than against another company.
Where Does Teledyne Technologies's Revenue Come From?

What the Segment Figures Do Not Show
The rows above add up to 100% of Teledyne Technologies'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 Teledyne Technologies reported in the segment note and revenue disclosures of its Form 10-K filed February 20, 2026 (accession 0001094285-26-000017), 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.
