WTRG vs XYL: How Essential Utilities and Xylem was spun out of ITT in 2011 and has become the largest publicly traded pure-play water technology company Compare (2026)

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.

Reading it: WTRG is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

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. WTRG 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 WTRG 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.

Essential Utilities, based in Bryn Mawr, Pennsylvania and formerly known as Aqua America, is one of the largest publicly traded regulated water and wastewater companies in the United States. Through its Aqua brand it serves roughly 5.5 million water and wastewater customers across nine states, and through its Peoples brand it delivers natural gas to about 747,000 customers concentrated in western Pennsylvania. Earnings come almost entirely from regulated rates, so growth is driven by heavy infrastructure spending (about $1.4 billion invested in 2025) that expands the rate base regulators allow it to earn a return on.

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.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• WTRG drivers: Pending American Water merger; Rate-base growth from infrastructure spending.
• XYL drivers: Aging infrastructure and water scarcity; Digital water and smart metering.

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 largest single risk is merger-specific: if remaining regulatory approvals are delayed, conditioned, or denied, WTRG would revert to trading on its standalone fundamentals, and the merger agreement carries termination fees ($370 million potentially payable by Essential, $835 million by American Water under specified circumstances). 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.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick WTRG if you believe its drivers more; XYL if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the WTRG and XYL guides.

WTRG. WTRG trades like a regulated utility, valued on stable earnings and its dividend rather than rapid growth, and full-year 2025 revenue rose about 19 percent to roughly $2.5 billion, helped by rate recoveries and higher gas costs. With the American Water merger approved by shareholders, the stock's valuation increasingly reflects the fixed 0.305 exchange ratio and the roughly Q1 2027 expected close. Reported quarterly EPS can swing on non-recurring items and merger-related expenses, so headline comparisons should be read carefully.

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): WTRG shows revenue (fy2025) ~$2.5B, net income (fy2025) ~$616M, eps (fy2025) ~$2.20, market cap ~$11B; XYL shows revenue (ttm) ~$9.1B, q1 2026 revenue ~$2.1B, 2026 revenue guidance (midpoint) ~$9.25B, q1 2026 adjusted eps ~$1.12.

WTRG 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 WTRG and XYL exposure against your real portfolio. It is not an investment adviser.
