Zurn Elkay’s Q2 results showcased the compounding impact of its business system, with margin expansion and continued outperformance in high-value segments. The strategic acquisition of IntelliHot, tankless water heater innovator, signals a deliberate push into regulatory-driven adjacencies with robust margin profiles. Management’s raised outlook, anchored by disciplined portfolio pruning and operational leverage, points to sustained above-market growth and cash generation.
Summary
- IntelliHot Acquisition Unlocks New Adjacency: Zurn Elkay enters the $1.1B commercial water heating market, targeting tankless growth and regulatory tailwinds.
- Margin Expansion Driven by Business System: 820 basis points of margin improvement over 14 quarters reflects relentless operational focus and product mix discipline.

Business Overview
Zurn Elkay Water Solutions, a leading provider of engineered water solutions, generates revenue through the sale of plumbing, water safety, drinking water, and flow control products. The business is organized around core verticals in institutional and commercial non-residential construction, with major segments including water safety and control, drinking water, flow systems, and hygienic and environmental products. The company’s model blends new construction sales with a significant maintenance, repair, and operations (MRO) base, providing recurring revenue stability.
Performance Analysis
Q2 delivered 10% organic sales growth and 120 basis points of EBITDA margin expansion, marking a record 27.7% margin since the Zurn Elkay merger. The quarter’s overperformance was led by robust demand in water safety and control and drinking water product lines, both exceeding average growth rates. Price realization contributed 5% of growth, with volume gains concentrated in the highest-margin categories.
Operating leverage, productivity gains from the Zurn Elkay Business System (ZEBS), and a disciplined exit from low-margin SKUs drove profitability. Free cash flow reached $112 million, supporting $50 million in share repurchases and the IntelliHot acquisition. The business continues to benefit from a strategic focus on high-value adjacencies and ongoing cost structure improvements.
- Product Mix Shift: Fastest growth in water safety, drinking water, and flow systems, all above fleet average margin.
- Recurring Revenue Strength: MRO and retrofit now represent roughly 50% of business, creating a hedge against new construction cycles.
- Leverage at Historic Low: Net debt leverage at 0.3x, providing ample flexibility for investment and M&A.
Tariff-related cash refunds provided a non-recurring boost, but were excluded from adjusted results, keeping the underlying margin story clean. The company’s incremental EBITDA margin remains at 40%, outpacing prior targets and reflecting the compounding benefit of operational discipline.
Executive Commentary
"What you're seeing in our results and outlook is the compounding benefit of the success of those things happening over the last three to four years. Where the fastest growing parts of our business also happen to be amongst our most profitable."
Todd Adams, Chairman and CEO
"The strong margin in the year-over-year expansion was driven by operating leverage on higher volume, continued productivity from our Zern Elkay business system and ongoing mixed improvement as our highest margin products continue to lead our growth."
Dan Kuhn, Chief Financial Officer
Strategic Positioning
1. Adjacency Expansion via IntelliHot
IntelliHot, tankless water heater platform, brings a $37 million sales base with 50% gross margins and low teens EBITDA margins. Zurn Elkay aims to scale IntelliHot to $100 million in sales and 30% EBITDA margin within five to six years, leveraging its specification, channel, and supply chain advantages. The acquisition targets the rapidly growing tankless segment, fueled by regulatory efficiency mandates and health-driven owner preferences.
2. ZEBS-Driven Operational Excellence
The Zurn Elkay Business System, continuous improvement framework, underpins margin gains through associate-led process innovations, structural cost reduction, and portfolio simplification. Thousands of incremental “CI” ideas, combined with 80-20 SKU focus, have systematically shifted the business toward higher-margin, faster-growing categories.
3. Portfolio Pruning and Capital Reallocation
Management’s disciplined exit from low-margin residential sinks and other non-core SKUs has freed resources for reinvestment in high-growth adjacencies and product innovation. The strategic review process, including periodic product lifecycle management, ensures resources are continually redeployed to areas with sustainable competitive advantage.
4. Innovation in Drinking Water
Elkay Pro Filtration, proprietary filtration system, differentiates the drinking water segment with enhanced features, ease of maintenance, and connected technology. Filtered units now comprise over 60% of sales, with a target of 70% by 2027. The installed base expansion fuels recurring filter revenue and strengthens MRO exposure.
5. Supply Chain Resilience and Tariff Mitigation
Ongoing supply chain optimization, including China sourcing reduction, has lowered landed costs and mitigated geopolitical risk. The company successfully navigated tariff transitions, with new Section 301 tariffs incorporated into forward guidance.
Key Considerations
This quarter exemplifies Zurn Elkay’s playbook of compounding operational gains, strategic adjacency bets, and disciplined portfolio management, all while maintaining sector-leading margins and cash flow.
Key Considerations:
- Adjacency Growth Trajectory: IntelliHot is a template for future category expansions, with management targeting $100-200 million addressable markets and $20-30 million of new revenue per adjacency over three years.
- Recurring Revenue Mix: MRO and retrofit sales provide downside protection and cash flow stability, especially as new construction cycles moderate.
- Product Innovation as Differentiator: Proprietary filtration and connected tech in drinking water set Zurn Elkay apart in specification-driven markets.
- Supply Chain as Strategic Asset: Diversification away from China and continuous cost reduction underpin margin resilience.
- Portfolio Discipline: Ongoing 80-20 reviews ensure capital is focused on growth engines, with further pruning expected as part of annual strategic planning.
Risks
Execution risk remains around integration of IntelliHot, especially in scaling EBITDA margin to target levels. Regulatory shifts, particularly around tariffs or water quality, could alter cost structures or demand. Competitive intensity in core and adjacent categories may pressure price or share, while any cyclical downturn in non-residential construction could weigh on volume despite MRO insulation. Management’s discipline in portfolio pruning must be maintained to avoid margin dilution from legacy SKUs or underperforming adjacencies.
Forward Outlook
For Q3 2026, Zurn Elkay guided to:
- Core sales growth of 6% to 7% year-over-year
- Adjusted EBITDA margin near 28%
For full-year 2026, management raised guidance:
- Adjusted EBITDA of $503 million to $513 million
- Free cash flow of at least $350 million (excluding tariff refunds)
Management highlighted:
- IntelliHot to contribute ~$15 million in net sales for the last five months of the year
- Guidance fully incorporates new Section 301 tariffs and assumes a normalized pricing environment in the back half
Takeaways
Zurn Elkay’s Q2 results reinforce its position as an operationally disciplined, margin-centric compounder with a clear playbook for adjacency expansion and recurring revenue growth.
- Margin Expansion as Core Value Driver: 820 basis points of margin improvement over 14 quarters is the product of relentless business system execution, portfolio focus, and supply chain optimization.
- Adjacency Playbook in Action: IntelliHot acquisition demonstrates a repeatable model for entering regulatory-driven, high-margin categories, with a clear path to scale and integration.
- Future Watchpoint: Investors should monitor IntelliHot integration, further adjacency launches, and the sustainability of incremental margins as the business targets new $100-200 million markets and maintains product innovation leadership.
Conclusion
Zurn Elkay’s Q2 2026 results highlight a business compounding operational gains into sector-leading profitability, while methodically expanding into high-growth adjacencies like tankless water heating. The raised outlook and continued cash flow strength underscore management’s conviction in its business system and portfolio discipline, positioning ZWS for sustained outperformance in water solutions.
Industry Read-Through
Zurn Elkay’s results and strategy provide a clear read-through for the broader building products and water solutions sector: Regulatory-driven adjacencies and MRO-centric models are emerging as durable growth engines, especially as new construction cycles moderate. The shift to tankless water heating, driven by DOE efficiency mandates and owner health concerns, signals an accelerating transition for commercial plumbing suppliers. Supply chain resilience and SKU discipline are now table stakes for margin leadership, while recurring revenue streams from installed base expansion and product innovation (such as connected filtration) will increasingly differentiate winners from laggards. Investors in adjacent sectors should watch for similar adjacency moves and the compounding effect of operational excellence as key sources of future value creation.
