Data center demand offsets a sluggish residential market

01 Running thesis

A steady pipe supplier finds new growth pockets

Core & Main sits in a useful part of the economy. Cities, contractors, and water companies need pipes, valves, meters, hydrants, drainage products, and fire protection parts. Much of that demand is tied to repair and replacement, giving the business a stable base.

The bull case focuses on how the company is scaling new growth drivers while returning capital. In Q2 fiscal 2026, net sales grew 2.5 percent to $2.14 billion, and adjusted EBITDA rose 3 percent to $274 million. Fire protection sales jumped 14 percent year over year, heavily supported by data center construction. The company also put its cash to work, buying back $169 million in stock during the quarter.

The bear case centers on sluggish core volumes and a weak housing market. Residential lot development remains challenged, with segment sales down by a high single digit percentage in Q2. Because everyday volume is muted, the company relies heavily on specialty verticals like data centers and large, complex municipal projects.

Looking ahead, investors are watching the acquisition pipeline. Management noted that deal talks have accelerated after a quiet period. Closing those deals could help restore the inorganic growth engine the company depends on.

Sep 2026▲Q2 fiscal 2026 results showed a 2.5 percent increase in net sales, supported by fire protection and treatment plant solutions. The company also repurchased $169 million in shares.
Jun 2026→The Q1 fiscal 2026 10-Q confirmed flat net sales of $1.91 billion and gross margin of 27.2 percent. The thesis stayed balanced because margin execution improved, but organic volume fell about 1 percent.
Jun 2026▲Q1 fiscal 2026 earnings added evidence that newer growth areas are helping. Fire Protection sales rose 17 percent year over year, Smart Utility grew 9 percent, and the company repurchased $88 million of stock.
Mar 2026→Fiscal 2025 results set the current frame with $7.65 billion of net sales and $931 million of adjusted EBITDA. Private label reached about 5 percent of sales.
Dec 2025▲Q3 fiscal 2025 showed margin progress in a slow market. Gross margin expanded to 27.2 percent, and the company announced $30 million of annualized cost reductions.
Sep 2025▲Q2 fiscal 2025 sales rose 6.6 percent, and management raised the low end of full-year guidance. The board also increased the share repurchase authorization by $500 million.
Jun 2025▲Q1 fiscal 2025 sales rose 9.8 percent, helped by mid single digit organic volume growth and acquisitions. Municipal demand remained the main steady support.
02 Business model

Local branches, national buying power

Core & Main makes money by buying specialized infrastructure products from more than 5,000 suppliers and selling them to more than 60,000 customers. Its more than 370 branches give it local knowledge, while its national scale helps it buy, stock, and deliver products that smaller distributors struggle to handle.

The company holds an estimated 20 percent share in a fragmented market. That leaves room to buy smaller distributors and fold them into the branch network. With the acquisition pipeline accelerating, this strategy remains central to the growth algorithm.

Margins are a big part of the story. Private label products were about 5 percent of fiscal 2025 sales, with a long-term target of at least 10 percent. If Core & Main can sell more of its own branded products and keep tight control of sourcing and pricing, it can protect profits even when volume is slow.

The model faces pressure if construction demand weakens too much or if product costs move faster than selling prices. PVC pricing was a headwind earlier in the year, though management noted it stabilized sequentially in the second quarter.

03 Product portfolio

What runs through the branches

Cash cow

Water and Wastewater

This includes pipes, valves, hydrants, fittings, and smart meter products. Many items must meet water rules and local city specs, which makes service and product knowledge important.

Steady

Storm Drainage

Core & Main sells corrugated piping systems, retention basins, drains, manholes, grates, and geosynthetics. Demand is tied to site work, flood control, and construction activity.

Growth engine

Fire Protection

This line includes pipes, sprinkler heads, suppression systems, and fabrication services. Sales rose 14 percent year over year in Q2 fiscal 2026, driven by data center construction.

Growth engine

Smart Utility

Smart meters and related products help utilities measure and manage water use. The company continues to win large implementation contracts in this category.

Option

Integrated Solutions

Treatment plant products and fusible HDPE applications are scaling well. Treatment plant projects now make up a mid single digit percentage of total sales.

Option

Private Label

Core & Main sells its own branded products across water, wastewater, geosynthetics, and fire protection uses. Private label represents about 5 percent of sales.

04 Business segments

Three end markets, one broad customer base

Municipal44%flat
Non-Residential38%modest
Residential18%declining

The end-market mix is from fiscal 2025 management commentary: Municipal 44 percent, Non-Residential 38 percent, and Residential 18 percent. No single customer accounts for more than 1 percent of annual sales.

05 Risk factors

What could crack the setup

Data center strength fades

Medium impact · Medium odds

Fire protection sales grew 14 percent year over year in Q2 fiscal 2026, helped by data center construction. That strength offsets softer residential demand. If data center projects slow, the mix will look less favorable.

We watchFire protection sales growth and management comments on data center project activity.

Residential stays weak

Medium impact · High odds

Residential lot development is the most challenged end market, with Q2 sales down in the high single digits. Higher interest rates make builders slower to start projects. A long slump limits one of the company's paths to faster organic growth.

We watchResidential end-market commentary, builder confidence, and any sign of lot development recovery.

M&A execution slips

Medium impact · Medium odds

Core & Main uses acquisitions as part of its growth plan. Management said the deal pipeline accelerated significantly in recent months. More deals help growth, but they also raise the chance of integration mistakes or poor pricing.

We watchDeal pace, integration updates, acquired sales contribution, and whether margins hold after acquisitions.

Large project timing delays

Low impact · Medium odds

The shift toward larger, complex projects like smart utility rollouts introduces lumpiness. Start-time delays can pressure near-term volume realization and make quarterly revenue harder to predict.

We watchUpdates on large project implementations like the Miami-Dade smart utility rollout.
06 Quick answers

In one breath

What does Core & Main do?

Core & Main distributes products used in water, wastewater, storm drainage, and fire protection systems. Its customers include municipalities, private water companies, and professional contractors.

Why does municipal demand matter for CNM?

Municipal demand is tied to water infrastructure that cities must maintain. That can make it steadier than private construction, especially when interest rates pressure housing.

What is the main growth driver for Core & Main right now?

Near-term growth is coming from Fire Protection, Smart Utility, treatment plant products, and acquisitions. Fire Protection was a standout in Q2 fiscal 2026, supported by data center construction.

What is the biggest risk for CNM stock?

The biggest risk is that organic growth stays weak while pricing headwinds continue. If that happens, margin gains and buybacks may not be enough to drive a stronger stock story.
