ROP vs WTRG: How Roper Technologies has spent the past decade reinventing itself from an industrial tools and equipment maker into a diversified holding company whose center of gravity and Essential Utilities 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.

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. ROP and WTRG 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 ROP and WTRG 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.

Roper Technologies has spent the past decade reinventing itself from an industrial tools and equipment maker into a diversified holding company whose center of gravity is vertical-market software. It operates through three segments: Application Software (businesses like Deltek for government contractors, Vertafore in insurance, Aderant for law firms, Frontline in K-12 education, and Clinisys in diagnostics), Network Software (network-effect platforms such as DAT in freight and iPipeline in insurance), and Technology Enabled Products (Neptune water meters, Verathon and CIVCO in medical devices). More than half of total revenue is now recurring, coming from SaaS subscriptions, maintenance and transaction fees, and application plus network software together generate roughly three-quarters of revenue.

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.

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

• ROP drivers: Acquisition-driven compounding; Recurring, high-margin software mix.
• WTRG drivers: Pending American Water merger; Rate-base growth from infrastructure spending.

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 clearest risk is valuation: ROP trades at a premium multiple, so disappointing results or a slower deal pace can compress the stock even if the business stays healthy. For WTRG, 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).

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 ROP if you believe its drivers more; WTRG 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 ROP and WTRG guides.

ROP. Roper's Q1 2026 revenue rose about 11% year over year to roughly $2.10 billion, split between 6% organic growth and 5% from acquisitions, and it raised full-year adjusted earnings guidance while adding to its buyback authorization. Net margins sit near 19% to 20% and adjusted EBITDA margins around 38%, reflecting the software-heavy mix. The forward multiple in the mid-to-high teens is well below the stock's longer-run median, which bulls read as more reasonable and bears view as still-full for a business dependent on ongoing M&A.

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.

Headline figures (approximate, JULY 2026): ROP shows revenue (ttm) ~$8.0 billion, q1 2026 revenue ~$2.10 billion (up ~11% YoY), market cap ~$35-36 billion, fy2026 adjusted deps guidance ~$21.80-$22.05; WTRG shows revenue (fy2025) ~$2.5B, net income (fy2025) ~$616M, eps (fy2025) ~$2.20, market cap ~$11B.

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