Advanced Drainage Systems, Inc.

First-quarter net sales increased 21% year over year to $1 billion. Organic sales increased 9%; excluding a $25 million to $30 million pull-ahead from Q2, organic growth was described as mid-single digits. Stormwater revenue rose 24% to $809 million, while wastewater revenue increased 8%. Adjusted EBITDA increased 29% to $358 million, and adjusted EBITDA margin expanded to 35.8% versus 33.5% a year ago, a 230-basis-point improvement. Free cash flow was $203 million, net leverage was approximately 1.5x, and available liquidity was approximately $901 million. Full-year guidance was unchanged: net sales of $3.350 billion to $3.550 billion and adjusted EBITDA of $1 billion to $1.05 billion. Management said Q2 should see a worse-than-normal sequential margin step-down versus the typical 300 bps decline from Q1, as resin costs become a larger headwind; transportation costs should remain elevated through the year. The company expects first-half revenue to be 55% to 60% of the full-year total, with pricing intended to offset inflation dollar-for-dollar.

Scott Barbour framed ADS as a pure-play water company with secular tailwinds from aging infrastructure, storm intensity, and water management needs. He emphasized the company’s differentiated growth model: material conversion, innovation, partnerships, distributor programs, and acquisitions, with NDS already validating the acquisition thesis. His tone was confident but realistic, noting the demand environment remains tepid and cost inflation is dynamic, while stressing the company’s ability to generate strong cash flow and reinvest wisely.

Scott Cottrill focused on the quarter’s financial strength and the mechanics behind it: $1 billion in sales, $358 million of adjusted EBITDA, a 35.8% margin, and $203 million of free cash flow. He said the quarter benefited from strong organic volume, NDS, a $25 million to $30 million pull-ahead, and timing of pricing versus higher material costs. He also highlighted a solid balance sheet with 1.5x net leverage, $901 million of liquidity, and about $200 million of expected capex this fiscal year for Cordele, automation, and Infiltrator capacity, while reiterating that pricing should offset inflation on a dollar-for-dollar basis for the year.

Analysts pressed management on whether Q2 margins could compress below 30% given the resin step-up and pre-buy pull-forward. Management said sequential margins will be worse than the typical 300 bps Q1-to-Q2 decline, but they did not give a specific Q2 margin target; they emphasized pricing is already in place while resin costs will peak in Q2 and Q3. Questions on NDS centered on seasonality, integration, and cross-selling; management said Q1 was NDS’s highest quarter, integration is progressing well, and cross-selling is still early but showing opportunity. Analysts also asked about recycled content, freight inflation, and the pace of the Georgia recycling facility ramp, with management saying recycled content is being pushed back toward 50% over time, the facility is already helping mitigate costs, and transportation inflation will remain elevated but is partly hedged by the internal fleet.
