Core & Main Q1 FY2026 earnings showed flat sales, stronger margins, EPS growth and healthy municipal water infrastructure demand, while residential construction remained weak.

Key Highlights

  • Core & Main Q1 net sales were nearly flat at $1.91 billion.
  • Gross margin expanded 50 basis points to 27.2%.
  • The company reaffirmed fiscal 2026 sales and EBITDA guidance.

Core & Main delivered a steady first quarter of fiscal 2026, with flat revenue, stronger margins and higher earnings despite a mixed construction backdrop. Municipal water infrastructure demand remained resilient, while residential lot development stayed weak and some commercial construction categories remained uneven.

Core & Main is a specialized distributor of water, wastewater, storm drainage and fire protection products and related services. The company serves municipalities, private water companies and contractors across the United States and Canada, with a broad portfolio that includes pipes, valves, fittings, hydrants, storm drainage systems, fire protection equipment and smart utility solutions.

For Core & Main, Inc. (NYSE:CNM), the quarter was less about rapid revenue acceleration and more about execution. Management showed margin discipline, maintained full-year guidance and continued returning capital to shareholders through buybacks.

Revenue Was Stable Against a Tough Comparison

Core & Main reported first-quarter net sales of $1.91 billion, essentially flat from the prior-year period. Organic volumes declined about 1%, while acquisitions contributed roughly one percentage point of growth.

The headline sales figure was slightly below market expectations, but the underlying performance needs context. The company was lapping a strong prior-year quarter when end markets, especially residential, were more supportive. Management estimated overall end-market demand was down low single digits in Q1.

Pipes, valves and fittings, as well as storm drainage, were pressured by lower volume. Fire protection products performed better, helped by higher volume, stronger selling prices and demand from data centers and multifamily projects. Smart utility sales also increased on higher volume.

Municipal Demand Remains the Core Stabilizer

The strongest part of Core & Main’s demand profile remains municipal infrastructure. Management said municipal demand stayed healthy, supported by repair-and-replace activity, aging water infrastructure and the largely non-discretionary nature of water system investment.

This matters because municipal water infrastructure is less cyclical than private construction. Water utilities still need to maintain pipes, treatment systems, storm drainage assets and metering infrastructure even when housing or commercial construction slows.

Management also noted that about 95% of water infrastructure funding is supported by state and local sources. That reduces reliance on a single federal spending cycle and supports a more durable long-term demand base.

Smart Utility and Treatment Plant Solutions Add Growth

Core & Main continues to benefit from higher-value infrastructure categories. Smart utility solutions grew high single digits in the quarter, while treatment plant solutions delivered double-digit growth.

Smart utility includes advanced metering infrastructure, software, analytics, installation and support. These systems help utilities improve billing accuracy, reduce non-revenue water and better manage aging networks.

Treatment plant solutions are also becoming a more important growth platform. These projects include upgrades, rehabilitation and modernization of water and wastewater facilities. Management said treatment plant solutions have delivered a strong five-year growth profile and remain one of the company’s fastest-growing product initiatives.

These businesses are strategically important because they shift Core & Main beyond basic product distribution toward integrated infrastructure solutions with higher technical content.

Margin Expansion Offset Weak Volume

Core & Main’s gross profit rose 2% to $520 million, while gross margin expanded 50 basis points to 27.2%. The improvement was driven by private label growth, sourcing optimization and disciplined pricing and purchasing execution.

Adjusted EBITDA increased 0.9% to $226 million, while adjusted EBITDA margin rose 10 basis points to 11.8%. Net income increased 7.6% to $113 million. Diluted EPS rose 9.6% to $0.57, and adjusted diluted EPS increased 5.9% to $0.72.

The EPS growth was supported by higher net income and a lower share count after repurchases. This is an important point for investors because earnings growth was achieved despite flat sales and soft end-market volume.

Buybacks Signal Capital Discipline

Core & Main generated $82 million of operating cash flow in the quarter, up from $77 million a year earlier. The company ended the quarter with net debt of about $2.0 billion and net leverage of 2.2 times, which remains within its target range.

Capital allocation was active. Core & Main repurchased $88 million of shares during the quarter and another $37 million after quarter-end. That brings fiscal year-to-date repurchases to $125 million.

The company is balancing buybacks with continued investment in greenfield expansion and potential acquisitions. It opened five new greenfield locations during the quarter and expects to open a record 8 to 10 greenfield locations in fiscal 2026.

Guidance Reaffirmed Despite Macro Uncertainty

Core & Main reaffirmed its fiscal 2026 outlook. The company still expects net sales of $7.8 billion to $7.9 billion, adjusted EBITDA of $950 million to $980 million and adjusted EBITDA margin of 12.2% to 12.4%.

Management expects overall end-market volumes to be roughly flat for the year. Municipal demand is expected to remain strong, while private construction is likely to remain cautious. Residential markets remain challenged, particularly in Sun Belt lot development, although management said conditions have stabilized relative to the end of fiscal 2025.

PVC pricing remains an important variable. Management said PVC was a year-over-year headwind in Q1, but supplier price increases could become a modest sequential tailwind later in the year.

Conclusion

Core & Main’s Q1 FY2026 earnings showed the resilience of a water infrastructure distributor operating through a softer construction cycle. Sales were flat, but margin expansion, smart utility growth, treatment plant momentum and share repurchases supported earnings growth.

The main risk is timing. If residential and light commercial demand remain soft, revenue growth may take longer to accelerate. But municipal infrastructure, data centers, smart metering and treatment plant modernization provide durable long-term growth drivers. For CNM, the investment debate now turns on whether margin gains and capital allocation can bridge the period until private construction demand improves.
