Advanced Drainage Systems, Inc. supplies plastic pipe and related products that construction and agricultural projects use to collect, move, store and treat stormwater. Stormwater products generate most of its sales. It sells pipe together with compatible drainage products for underground construction projects; its NDS business also supplies residential drainage products. Distributors buy most of its output for resale, with Ferguson Enterprises and Core & Main each accounting for a substantial share of sales. A relatively small group of large customers supplies much of its revenue.
The company also supplies systems that treat wastewater where centralized sewers are unavailable. Its Infiltrator business makes plastic tanks, chambers and treatment systems, serving primarily residential uses in the United States and Canada. This gives it a second source of product sales tied to homes and communities that need onsite wastewater treatment.
Demand depends on construction activity, infrastructure spending and agricultural drainage projects, and weather affects when work proceeds. Plastic resin is its principal raw material, so profitability depends heavily on passing higher material costs to customers. Its onsite and decentralized wastewater treatment systems cannot be sold without regulatory approval; approvals also matter for getting its N-12 and SaniTite HP pipe specified and accepted for projects.
The risk section is the longest, dullest part of the filing. This keeps only what can really hurt you: where it hits, how hard, when it plays out.
Every company claims an edge. Each one is checked against hard numbers like margins and returns: which hold, and which line gives way first.
ADS depends on Core & Main, Inc. to buy and distribute its drainage products: those purchases accounted for 12.8% of ADS’s fiscal 2026 net sales. Core & Main sells water and storm-drainage supplies to infrastructure projects, so its stormwater product sales offer a window into demand for ADS’s pipes and drainage systems.
Ferguson Enterprises Inc. is a major buyer of ADS’s drainage products, accounting for 13.1% of ADS’s fiscal 2026 net sales. Ferguson distributes water and wastewater products to construction customers; sales to those customers are worth watching for clues to demand for ADS’s stormwater and wastewater systems.
Eagle Materials, Inc. and ADS depend on spending in the same U.S. construction markets: Eagle sells cement and concrete for infrastructure and buildings, while ADS supplies stormwater pipes and drainage systems. Watch Eagle’s cement business for clues to infrastructure demand, its main market for cement and concrete.
Housing Starts (Sep)
For Advanced Drainage Systems, new-home construction readings track homebuilding that can drive purchases of stormwater pipe and drainage products and, where homes lack centralized sewer access, onsite wastewater systems.
Expected1.31MLast release1.275M
If it comes in above expectations
If the reading is above the 1.31M estimate, it is above the previous 1.275M. More starts or permits than expected can lift demand from homebuilders and distributors for Advanced Drainage Systems’ stormwater products, while more rural homes without centralized sewer access can also support purchases of its onsite wastewater systems.
If it comes in below expectations
Fewer starts or permits than expected can weaken homebuilding demand, reducing distributors’ purchases of Advanced Drainage Systems’ stormwater products and potentially limiting demand for onsite wastewater systems in rural areas.
ADVANCED DRAINAGE SYSTEMS, INC. earningsThis company
Advanced Drainage Systems' report will show whether sales of its stormwater and wastewater products can grow while the company preserves its gross margin as material costs and selling prices shift.
Read Stormwater and Wastewater sales alongside gross margin—the share of sales left after product costs. Growth in both businesses with a steady or rising margin would show that project demand and cost pass-through are supporting profitable growth. Weaker sales or a falling margin would point to softer construction demand, or resin costs and competitive pricing squeezing what ADS keeps from each sale.
Ferguson Enterprises Inc. earningsFERG
Ferguson Enterprises' report will show whether construction customers are buying steadily through a distributor that accounted for 13.1% of Advanced Drainage Systems' fiscal 2026 sales.
Look at Ferguson's sales to construction customers, especially demand for water and wastewater products. Steady or recovering sales would suggest demand through this important distributor remains supportive of Advanced Drainage Systems' drainage products. Weakening sales would raise the risk of reduced channel orders, not prove that ADS sales have already fallen.
Core & Main, Inc. earningsCNM
Core & Main's report will show whether infrastructure projects are buying storm-drainage supplies through a distributor that accounted for 12.8% of Advanced Drainage Systems' fiscal 2026 sales.
Look at Core & Main's storm-drainage product sales. Steady or growing sales would indicate infrastructure demand is holding up and support an important distributor channel for Advanced Drainage Systems. A decline could signal softer project purchasing and pressure on ADS pipe and drainage-system demand, but would not establish that ADS sales have fallen.
