How Does Xylem Inc. Make Money?
No single line supplies a majority of revenue: the largest, Water Infrastructure, is 29%, which spreads Xylem Inc.'s exposure across several demand drivers. Between fiscal 2024 and 2025, Measurement and Control Solutions grew fastest (+11.5%) and Applied Water slowest (+3.1%), so the revenue mix tilts toward Measurement and Control Solutions while that gap lasts.
| Segment | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
|---|---|---|---|---|
| Water Infrastructure | $2.6 billion | $2.6 billion | 29.2% | 3.2% |
| Water Solutions Services | $2.5 billion | $2.3 billion | 27.3% | 5.2% |
| Measurement and Control Solutions | $2.1 billion | $1.9 billion | 23.1% | 11.5% |
| Applied Water | $1.8 billion | $1.8 billion | 20.5% | 3.1% |
Which Xylem Inc. Segments Earn the Most?
| Segment | FY2025 segment operating income | Segment margin |
|---|---|---|
| Water Infrastructure | $462 million | 17.5% |
| Water Solutions Services | $302 million | 12.3% |
| Measurement and Control Solutions | $244 million | 11.7% |
| Applied Water | $312 million | 16.9% |
Segment operating income is the profit measure Xylem Inc. 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 Xylem Inc. more safely than against another company.
What Does Xylem Inc. Sell?
Xylem Inc. 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 | $7.5 billion | $7.1 billion | 82.7% | 5.3% |
| Service | $1.6 billion | $1.5 billion | 17.3% | 6.5% |
What the Segment Figures Do Not Show
The rows above add up to 100% of Xylem Inc.'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 Xylem Inc. reported in the segment note and revenue disclosures of its Form 10-K filed February 25, 2026 (accession 0001524472-26-000012), 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.
