AWK vs WTS: How American Water Works and Watts Water Technologies supplies products that manage the flow of fluids and energy into Compare (2026)

Last updated July 2026

Short answer

AWK is the larger of the two ($25.52B market cap): the incumbent the market prices for continued execution (19.93x forward earnings, beta 0.60). WTS is the smaller challenger ($11.77B), actually pricier on forward earnings (26.81x): more room to run, but more to prove. The real question is which set of drivers you believe, and whether owning one (or both) leaves you over-concentrated.

AWK vs WTS: 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.

MetricAWKWTSWhat it tells you
Market cap$25.52B$11.77BSize. The larger name is the incumbent; the smaller has more room to grow and more to prove.
Forward P/E19.9326.81Valuation 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/E23.1332.27Valuation 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.
Beta0.601.13Volatility 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 range37% of range72% of rangeWhere 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 / book2.315.61How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price.

Reading it: AWK 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.

Before you buy: how AWK and WTS 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 WTS 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 WTS 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 Watts Water Technologies supplies products that manage the flow of fluids and energy into (WTS) do?

Watts Water Technologies supplies products that manage the flow of fluids and energy into, through, and out of buildings: backflow preventers, pressure regulators, temperature and pressure relief valves, thermostatic mixing valves, leak-detection systems, commercial washroom and hydration solutions, and increasingly smart, connected water controls. It sells across the Americas, Europe, and Asia-Pacific and Middle East and Africa, largely into the plumbing, HVAC, and building-safety channels, where much of the demand is non-discretionary repair, replacement, and code-driven installation.

AWK vs WTS: 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.
  • WTS drivers: Non-discretionary replacement and code demand; Data-center and smart-water tailwinds.

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 WTS, watts is exposed to commercial and residential construction and renovation activity, so a downturn in building spend or higher-for-longer interest rates could pressure volumes.

AWK or WTS: which should you pick?

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 AWK if you believe its drivers more; WTS 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 AWK and WTS guides.

AWK vs WTS: 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.

WTS. Watts posted record first-quarter 2026 results with revenue near $677 million, up about 21 percent year over year, and diluted EPS of roughly $2.97, both ahead of estimates on data-center demand and pricing. For full-year 2026 the company guided to reported sales growth of about 8 to 12 percent, organic growth of 2 to 6 percent, and adjusted operating margin near 19 to 20 percent. At a mid-20s trailing P/E and a sub-1 percent yield, the shares are priced as a quality compounder rather than a value name.

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; WTS shows revenue (ttm) ~$2.6B, q1 2026 revenue ~$677M (up ~21% YoY), q1 2026 diluted eps ~$2.97 (adj ~$3.04), market cap ~$10B.

The bottom line: AWK vs WTS

AWK and WTS 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 WTS exposure against your real portfolio. It is not an investment adviser.

FAQ

What is the difference between AWK and WTS?

+

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. Watts Water Technologies supplies products that manage the flow of fluids and energy into, through, and out of buildings: backflow preventers, pressure regulators, temperature and pressure relief valves, thermostatic mixing valves, leak-detection systems, commercial washroom and hydration solutions, and increasingly smart, connected water controls. 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 WTS the better stock?

+

Neither is universally better. AWK is the larger incumbent; WTS is the smaller challenger and looks pricier on forward earnings. 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 WTS?

+

On forward P/E (as of July 2026), AWK trades at 19.93x and WTS at 26.81x, so AWK 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 WTS?

+

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 WTS?

+

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. WTS: Watts is exposed to commercial and residential construction and renovation activity, so a downturn in building spend or higher-for-longer interest rates could pressure volumes. The stock trades at a premium mid-20s earnings multiple, which leaves little room for disappointment if organic growth slows to the low single digits guided for 2026. Tariffs, input-cost inflation, and acquisition-related margin dilution are ongoing headwinds management must keep offsetting with price and productivity. The data-center tailwind, while real, could prove lumpy and hard to forecast quarter to quarter. Foreign-exchange swings and integration risk on acquisitions add further variability.
