Direct Answer
Agilent Technologies reports revenue across 3 business segments in its fiscal 2025 Form 10-K. Agilent Cross Lab is the largest, with $2.9 billion of revenue (42% of the total), followed by Life Sciences and Diagnostics Markets at $2.7 billion (39%).
How Does Agilent Technologies Make Money?
No single line supplies a majority of revenue: the largest, Agilent Cross Lab, is 42%, which spreads Agilent Technologies's exposure across several demand drivers. Between fiscal 2024 and 2025, Life Sciences and Diagnostics Markets grew fastest (+10.5%) and Applied Markets slowest (+1.3%), so the revenue mix tilts toward Life Sciences and Diagnostics Markets while that gap lasts.
| Segment | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
|---|---|---|---|---|
| Agilent Cross Lab | $2.9 billion | $2.7 billion | 41.9% | 5.9% |
| Life Sciences and Diagnostics Markets | $2.7 billion | $2.5 billion | 39.2% | 10.5% |
| Applied Markets | $1.3 billion | $1.3 billion | 18.9% | 1.3% |
Which Agilent Technologies Segments Earn the Most?
| Segment | FY2025 segment operating income | Segment margin |
|---|---|---|
| Agilent Cross Lab | $946 million | 32.5% |
| Life Sciences and Diagnostics Markets | $536 million | 19.7% |
| Applied Markets | $301 million | 22.9% |
Segment operating income is the profit measure Agilent 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 Agilent Technologies more safely than against another company.
What the Segment Figures Do Not Show
The rows above add up to 100% of Agilent 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 Agilent Technologies reported in the segment note and revenue disclosures of its Form 10-K filed December 22, 2025 (accession 0001090872-25-000087), 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.
