AWK vs XYL: How American Water Works and Xylem was spun out of ITT in 2011 and has become the largest publicly traded pure-play water technology company Compare (2026)
Last updated July 2026
Short answer
AWK (American Water Works) and XYL (Xylem was spun out of ITT in 2011 and has become the largest publicly traded pure-play water technology company) share investment themes but are different businesses. The right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
AWK vs XYL: the tie-breaker metrics
Same yardstick, side by side (as of July 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.
| Metric | AWK | XYL | What it tells you |
|---|---|---|---|
| Market cap | $25.52B | $28.81B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 19.93 | 19.87 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Trailing P/E | 23.13 | 30.15 | Valuation on the last 12 months. A big drop from trailing to forward means the market expects earnings to jump, so more growth is already in the price. |
| Beta | 0.60 | 1.02 | Volatility vs the market. Above 1 swings harder than the index; below 1 is steadier. Higher beta means bigger drawdowns to hold through. |
| Price vs 52-week range | 37% of range | 33% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
| Price / book | 2.31 | 2.57 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Before you buy: how AWK and XYL affect your concentration
The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. AWK and XYL share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.
This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined AWK and XYL exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

What does American Water Works (AWK) do?
American Water Works is the largest publicly traded, regulated water and wastewater utility in the United States, serving roughly 14 million people through regulated operations in 14 states plus 18 military installations. Its business model is classic rate-base utility economics: the company invests heavily in pipes, treatment plants, and water systems, then earns an allowed regulated return on that invested capital once state utility commissions approve rate cases. Growth comes from two levers, ongoing infrastructure spending and acquisitions of small municipal and investor-owned water systems that fold into its existing footprint.
What does Xylem was spun out of ITT in 2011 and has become the largest publicly traded pure-play water technology company (XYL) do?
Xylem was spun out of ITT in 2011 and has become the largest publicly traded pure-play water technology company, operating through four segments: Water Infrastructure (transport and treatment for utilities), Applied Water (pumps and equipment for building and industrial use), Measurement and Control Solutions (smart meters, sensors and the Sensus platform), and Water Solutions and Services (the outsourced treatment and services business built up by the 2023 Evoqua acquisition). Its customers are heavily weighted toward water and wastewater utilities plus industrial users, which gives it exposure to non-discretionary, regulation-driven spending on aging pipes, leak detection, metering and treatment.
AWK vs XYL: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- AWK drivers: Rate-base growth and capital investment; Acquisitions of municipal and small water systems.
- XYL drivers: Aging infrastructure and water scarcity; Digital water and smart metering.
Which fits which kind of investor
A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: The biggest risk is regulatory: earnings depend on state utility commissions approving rate cases at constructive returns, and regulatory lag (the gap between when capital is spent and when rates are allowed to recover it) can pressure results. For XYL, organic growth has been flat in recent quarters even as reported revenue grew, so the premium valuation leaves little room for disappointment if utility or industrial demand slows.
AWK or XYL: which should you pick?
AWK vs XYL: the full fundamentals
AWK. AWK typically trades at a premium P/E to the broader market, reflecting its regulated, low-volatility earnings and long runway of rate-base growth. In the first quarter of 2026 revenue rose year over year to about $1.21 billion while adjusted EPS was roughly $1.01 (versus about $1.02 a year earlier), and management reaffirmed full-year 2026 EPS guidance of about $6.02 to $6.12. The dividend yields roughly 2.5-2.8%, modest in absolute terms but growing near the top of the utility peer group.
XYL. Xylem generates roughly $9 billion in annual revenue and beat expectations in Q1 2026, delivering about $2.1 billion of revenue and around $1.12 in adjusted EPS while raising full-year guidance to a midpoint near $9.25 billion. At a market cap around $28 billion and a trailing P/E in the mid-30s, the stock trades at a premium to the broader industrials group, reflecting its pure-play water exposure and margin trajectory. Organic growth was roughly flat in the quarter even as reported revenue rose, so valuation leans on continued margin expansion.
Headline figures (approximate, JULY 2026): AWK shows market cap ~$26 billion, share price ~$135, q1 2026 revenue ~$1.21 billion, q1 2026 adjusted eps ~$1.01; XYL shows revenue (ttm) ~$9.1B, q1 2026 revenue ~$2.1B, 2026 revenue guidance (midpoint) ~$9.25B, q1 2026 adjusted eps ~$1.12.
The bottom line: AWK vs XYL
AWK and XYL are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined AWK and XYL exposure against your real portfolio. It is not an investment adviser.

FAQ
What is the difference between AWK and XYL?
+
American Water Works is the largest publicly traded, regulated water and wastewater utility in the United States, serving roughly 14 million people through regulated operations in 14 states plus 18 military installations. Xylem was spun out of ITT in 2011 and has become the largest publicly traded pure-play water technology company, operating through four segments: Water Infrastructure (transport and treatment for utilities), Applied Water (pumps and equipment for building and industrial use), Measurement and Control Solutions (smart meters, sensors and the Sensus platform), and Water Solutions and Services (the outsourced treatment and services business built up by the 2023 Evoqua acquisition). They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is AWK or XYL the better stock?
+
Neither is universally better; they suit different views and risk levels. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, AWK or XYL?
+
On forward P/E (as of July 2026), AWK trades at 19.93x and XYL at 19.87x, so XYL is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both AWK and XYL?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of AWK vs XYL?
+
AWK: The biggest risk is regulatory: earnings depend on state utility commissions approving rate cases at constructive returns, and regulatory lag (the gap between when capital is spent and when rates are allowed to recover it) can pressure results. As a capital-intensive utility carrying substantial debt, AWK is sensitive to interest rates, which raise financing costs and can compress the valuation multiple. The pending Essential Utilities merger adds integration and approval risk, and could be delayed or altered by remaining regulators. Weather, drought, and water-quality or environmental compliance costs can also affect a given period. Finally, the stock often trades at a premium valuation, so disappointing rate outcomes or higher-for-longer rates can weigh on the shares. XYL: Organic growth has been flat in recent quarters even as reported revenue grew, so the premium valuation leaves little room for disappointment if utility or industrial demand slows. A large share of revenue depends on municipal and utility budgets that can be delayed by funding cycles, elections or macro pressure. The company carries acquisition-related debt and goodwill from the Evoqua deal, and integration or synergy shortfalls would weigh on margins. Xylem also has meaningful international exposure, adding currency and regional demand risk. Finally, competition in metering and treatment from focused players can pressure pricing in specific product lines.
