Rexnord Corporation Stock Is No Longer RXN
Worldreview1989 -Investors searching for Rexnord Corporation stock may encounter an important problem: the old Rexnord Corporation ticker RXN no longer represents a standalone publicly traded company.
That distinction matters.
In October 2021, Rexnord separated its Process & Motion Control business and combined that business with Regal Beloit. Regal subsequently became Regal Rexnord Corporation (NYSE: RRX). The remaining Rexnord business became Zurn Water Solutions, which later combined with Elkay Manufacturing to form Zurn Elkay Water Solutions Corporation (NYSE: ZWS).
Therefore, a modern analysis of "Rexnord stock" needs to answer two different questions:
What happened to the original Rexnord investment?
Which current public company best represents the former Rexnord Water Management business?
For investors interested in the legacy Rexnord water-solutions business, Zurn Elkay (ZWS) is the relevant successor.
Rexnord Stock Timeline
| Period | Company / Ticker | What Happened |
|---|---|---|
| Before 2021 | Rexnord Corporation / RXN | Diversified industrial company |
| October 2021 | Rexnord PMC → Regal | Process & Motion Control business separated and combined with Regal |
| October 2021 | Zurn Water Solutions | Remaining Rexnord business changed identity |
| July 2022 | Zurn Elkay / ZWS | Zurn combined with Elkay |
| 2026 | Zurn Elkay / ZWS | Publicly traded water-solutions company |
The 2021 transaction was structured as a Reverse Morris Trust. Rexnord shareholders received an economic interest in the combined Regal business while continuing to own the Water Management platform.
This means investors should not simply search for RXN's historical share price and assume it represents today's company.
What Does Zurn Elkay Actually Do?
Zurn Elkay operates in the water-solutions market, supplying products and systems related to:
commercial plumbing;
water safety;
water conservation;
drainage;
water control;
drinking-water systems;
commercial and institutional infrastructure;
sustainable water management.
The company describes itself as a water-solutions provider focused on health, hydration, human safety and environmental sustainability.
For U.S. investors, this creates a potentially attractive investment thesis because water infrastructure is less dependent on consumer discretionary spending than many traditional industrial businesses.
A leaking commercial building still needs plumbing.
A hospital still needs water-management equipment.
A school still needs safe drinking-water systems.
A commercial building still requires drainage and plumbing infrastructure.
That gives Zurn Elkay a business model with an element of essential infrastructure demand.
What U.S. Investors Are Likely to Like About the Story
Rather than inventing reader comments or attributing opinions to specific American investors, the better way to interpret the "American reader review" angle is to identify the factors that are likely to matter most to U.S. investors.
1. The business is relatively easy to understand
Many investors prefer companies where the economic proposition is straightforward.
Zurn Elkay sells products that become part of physical water infrastructure.
That is easier to understand than highly speculative technology businesses whose future revenue depends on uncertain technological adoption.
2. Water efficiency is a structural theme
Water conservation is becoming increasingly important across commercial, institutional and industrial buildings.
The investment thesis is not simply "water is scarce."
The more interesting thesis is:
Buildings increasingly need to use, control and manage water more efficiently.
That potentially increases the value of products that reduce water waste, improve system reliability and help customers comply with changing building and environmental requirements.
3. The company has demonstrated strong margin expansion
Zurn Elkay generated $1.696 billion of net sales in 2025, up approximately 8% from $1.567 billion in 2024.
Adjusted EBITDA increased to $442 million, compared with $390 million in 2024.
That means adjusted EBITDA margin increased from approximately 24.9% to 26.1%.
The company also generated a record $317 million of free cash flow in 2025.
For an industrial investor, that combination is important:
Revenue growth + margin expansion + free-cash-flow generation
is generally more attractive than revenue growth alone.
2026 Financial Performance Is Even More Interesting
The second-quarter 2026 numbers provide an important update.
Zurn Elkay reported:
| Metric | Q2 2025 | Q2 2026 | Change |
|---|---|---|---|
| Net sales | $444.5M | $491.0M | +10% |
| Net income | $50M | $113M | +126% |
| Adjusted EBITDA | $117.9M | $136.0M | +15% |
| Adjusted EBITDA margin | 26.5% | 27.7% | +120 bps |
| Adjusted EPS | $0.42 | $0.50 | +19% |
The company reported 10% core-sales growth in the quarter, with growth across all product categories.
The first six months of 2026 were also strong.
Revenue reached $924 million, versus $833.3 million in the comparable 2025 period, representing approximately 11% growth. Operating income reached $234.4 million compared with $141.0 million a year earlier.
But There Is an Important Accounting Detail
Investors should not interpret the entire 2026 operating-income increase as purely operational improvement.
During Q2 2026, Zurn Elkay received a $47.6 million IEEPA reciprocal-tariff refund.
The company explicitly stated that excluding this item, operating income still increased by $27.1 million, with operating-margin improvement of approximately 380 basis points.
That distinction is important.
It suggests the underlying business improved substantially, but the headline GAAP numbers received an additional temporary benefit.
This is exactly the type of adjustment a fundamental investor should identify rather than simply copying headline EPS growth.
Balance Sheet: One of the Strongest Parts of the Thesis
At June 30, 2026, Zurn Elkay reported approximately:
$365 million cash
$287 million inventory
$953 million total current assets
The company reported net debt leverage of only 0.3x at June 30, 2026.
A 0.3x net-debt leverage ratio is significant because it gives management considerable financial flexibility.
Low leverage can allow the company to:
repurchase shares;
increase dividends;
fund acquisitions;
invest in manufacturing;
develop new products;
withstand cyclical downturns.
This is especially important for an industrial company because economic cycles can affect construction and commercial activity.
Capital Allocation Is Becoming Part of the Investment Thesis
Zurn Elkay repurchased approximately $50 million of stock during Q2 2026, equivalent to about 1 million shares.
In 2025, the company repurchased approximately $160 million of common stock and paid $64 million in dividends.
This creates a potentially attractive combination:
organic growth + margin expansion + buybacks + dividends + low leverage.
However, buybacks only create meaningful value when shares are repurchased at reasonable valuations.
That leads to the central valuation question.
Valuation: Good Company Does Not Automatically Mean Good Stock
The latest market data available in this analysis places ZWS around the mid-$40s per share, with a market capitalization around $7.9 billion and a trailing P/E around the high-20s.
That is not an obvious deep-value valuation.
The market is already assigning a premium to the company.
Investors therefore need to believe that Zurn Elkay can maintain:
high-single-digit or better organic growth;
strong EBITDA margins;
healthy free cash flow;
disciplined capital allocation;
relatively low leverage.
If growth slows substantially, the valuation multiple could become a headwind.
Unique Analytical Component: The "Water Infrastructure Compounder" Test
Here is the unique analytical framework I would use for Rexnord/Zurn Elkay rather than relying only on P/E.
Call it the:
Water Infrastructure Compounder Score
The investment case depends on five variables.
1. Organic Growth
The first question is whether revenue can consistently grow faster than inflation.
2026 signal: Strong
Core sales increased approximately 10% in Q2 and 11% in the first half.
2. Margin Expansion
Revenue growth becomes much more valuable when incremental revenue produces disproportionately higher operating profit.
2026 signal: Positive
Adjusted EBITDA margin increased from 26.5% to 27.7% in Q2.
3. Free Cash Flow Conversion
Industrial companies can report attractive earnings while consuming significant working capital.
Zurn Elkay generated $317 million of free cash flow in 2025, which is an important positive indicator.
4. Balance-Sheet Resilience
Net debt leverage of 0.3x provides substantial financial flexibility.
Signal: Strong
5. Valuation Discipline
This is the weak point.
A premium valuation means investors have already recognized much of the quality.
Signal: Watch carefully
My Rexnord/Zurn Elkay Investor Matrix
| Factor | Assessment | Investor Interpretation |
|---|---|---|
| Revenue growth | 🟢 Strong | 2026 growth is accelerating |
| EBITDA margin | 🟢 Strong | Margin expansion continues |
| Free cash flow | 🟢 Strong | Excellent cash-generation profile |
| Balance sheet | 🟢 Strong | Low leverage |
| Buybacks | 🟢 Positive | Supports per-share growth |
| Dividend | 🟢 Positive | Additional shareholder return |
| Water infrastructure exposure | 🟢 Attractive | Structural long-term theme |
| Cyclicality | 🟡 Moderate | Construction/commercial exposure remains |
| Tariff exposure | 🟡 Watch | 2026 refund complicates comparisons |
| Valuation | 🟡/🔴 Watch | Premium multiple reduces margin of safety |
The Most Important Question for Investors
The key question isn't:
"Is Zurn Elkay a good company?"
The evidence increasingly suggests that it is a high-quality industrial company.
The more important question is:
Can earnings grow fast enough to justify the valuation investors are currently paying?
That is a very different question.
A company can grow earnings by 10% per year and still produce disappointing stock returns if investors pay too much for those earnings.
Bull Case
The bullish thesis looks like this:
Water infrastructure demand
↓
10%+ organic growth
↓
Operating leverage
↓
Higher EBITDA margins
↓
Strong free cash flow
↓
Debt remains low
↓
Buybacks + dividends + acquisitions
↓
Higher EPS
If this cycle continues, ZWS could behave more like a long-term industrial compounder than a traditional cyclical manufacturer.
Bear Case
The bear thesis is also straightforward.
1. Valuation compression
If earnings growth slows but the P/E multiple remains elevated, the stock could fall even while earnings increase.
2. Construction slowdown
Commercial construction and renovation activity can weaken during economic downturns.
3. Tariff distortions
The $47.6 million tariff refund in Q2 2026 makes the headline improvement look stronger than the underlying recurring earnings growth.
4. Acquisition risk
Growth through acquisitions can create value, but poor acquisition discipline can increase goodwill and leverage.
5. Competition
The water-products market remains competitive, and pricing power cannot be assumed indefinitely.
What American Investors Should Watch Next
For U.S. investors following ZWS, the next earnings reports should be evaluated using five numbers rather than simply EPS.
Watch #1 — Core sales growth
If core growth remains around 8–10%, the growth thesis remains healthy.
Watch #2 — Adjusted EBITDA margin
A move toward or above 28% would strengthen the operating-leverage thesis.
Watch #3 — Free cash flow
Free cash flow should grow alongside earnings.
Watch #4 — Net debt leverage
Low leverage is one of the company's strategic advantages.
Watch #5 — Share count
If earnings increase while the number of shares declines, EPS can compound faster than net income.
Is Zurn Elkay a Buy?
For an investor searching for the old Rexnord Corporation stock, the first conclusion is straightforward:
RXN is no longer the correct ticker.
The relevant successor to the former Rexnord Water Management business is Zurn Elkay Water Solutions (NYSE: ZWS). The former Process & Motion Control business became part of today's Regal Rexnord (RRX).
From a fundamental perspective, ZWS currently presents an interesting combination of:
strong organic growth;
expanding margins;
substantial free cash flow;
low leverage;
shareholder returns;
exposure to long-term water-efficiency trends.
The main concern is valuation rather than business quality.
Investor conclusion:
Business quality: 8.5/10
Financial strength: 9/10
Growth profile: 8/10
Balance-sheet risk: 9/10
Valuation attractiveness: 6/10
Overall investment profile: 8/10
For a long-term investor, ZWS may be more interesting as a quality industrial compounder than as a deep-value opportunity.
The ideal entry point would therefore depend heavily on valuation and the investor's required margin of safety.
Which Is Right for You?
Long-term investor
ZWS may be attractive if you prioritize predictable industrial demand, strong cash generation and disciplined capital allocation.
Dividend investor
The dividend adds another component to total shareholder return, although ZWS is better viewed as a growth-and-quality industrial company than a pure high-yield stock.
Value investor
The company becomes more interesting when valuation compresses while the underlying earnings trajectory remains intact.
Growth investor
The strongest argument is not explosive revenue growth but the combination of organic growth and margin expansion.
Conservative investor
The low leverage and strong cash generation are positives, but valuation should still be monitored.
Final Verdict
The phrase "Rexnord Corporation stock" now refers to a historical investment situation rather than an active RXN-listed stock.
The corporate transformation created two distinct investment paths:
Former Rexnord Process & Motion Control → Regal Rexnord (RRX)
Former Rexnord Water Management → Zurn Elkay Water Solutions (ZWS)
For investors interested in the water-management legacy, ZWS is the company that deserves the current fundamental analysis.
The most compelling part of the story is not simply the water theme. It is the combination of double-digit recent sales growth, expanding margins, strong free cash flow and a very low net-debt burden.
The biggest risk is that investors may already be paying a premium for those qualities.
Therefore, the central investment rule is:
Buy the economics, but pay attention to the price.
For ZWS, the long-term thesis remains attractive—but the valuation determines how attractive the stock actually is.
