Advanced Drainage Systems, Inc. has realigned its reporting structure and provided unaudited recast historical segment financial information. Following the acquisition of National Diversified Sales, management now evaluates performance using two reportable segments, Stormwater and Wastewater, and has changed the segment profitability measure to Adjusted EBITDA.
The company states the segment realignment does not change previously reported consolidated net sales, income from operations, net income attributable to ADS, or earnings per share. Quarterly segment net sales and Adjusted EBITDA for fiscal 2026, 2025 and 2024 have been recast and furnished in Exhibit 99.1 for informational and supplemental purposes only, and are not amendments or restatements of prior financial statements.
Advanced Drainage Systems, Inc. provides an in-depth look at its business in its latest annual report, highlighting its role as a leading manufacturer of stormwater and onsite wastewater management solutions. The company now operates through two reportable segments, Stormwater and Wastewater, following a realignment that reflects its broader product mix and the impact of acquisitions.
On February 2, 2026, ADS completed the acquisition of National Diversified Sales, adding a strong residential stormwater portfolio such as channel drains, catch basins and access boxes. Earlier, the Orenco acquisition expanded advanced treatment technologies within the Wastewater segment. ADS supports these businesses with 64 manufacturing plants, 41 distribution centers and a fleet of about 600 tractors and 1,100 specialized trailers.
The report emphasizes ADS’s recycling and sustainability focus, converting roughly hundreds of millions of pounds of post-consumer and post-industrial HDPE and polypropylene into products each year and advancing 10‑year environmental goals. Key risks discussed include resin price and supply volatility, construction and agriculture cyclicality, customer concentration, climate and regulatory developments, cybersecurity, manufacturing disruptions and labor availability.
Advanced Drainage Systems reported solid growth for Q4 and fiscal 2026 while raising its dividend. Fourth quarter net sales rose 9.9% to $676.8 million, with stormwater revenue boosted by the NDS acquisition and 2% organic stormwater growth. Q4 Adjusted EBITDA increased 6.4% to $188.0 million, though GAAP net income from continuing operations fell to $35.2 million due to acquisition, restructuring and realignment costs.
For fiscal 2026, net sales grew 5.0% to $3,050.4 million and Adjusted EBITDA increased 8.3% to $962.9 million, lifting the Adjusted EBITDA margin to 31.6%. Adjusted EPS from continuing operations rose to $6.27, while reported diluted EPS from continuing operations edged down to $5.45. Cash from operations reached $819.1 million and free cash flow was $569.3 million.
The company closed the NDS acquisition, realigned into Stormwater and Wastewater segments, and increased net debt to $1,548.9 million, resulting in a 1.6x leverage ratio as of March 31, 2026. Management issued fiscal 2027 targets of $3.35–$3.55 billion in net sales and $1.0–$1.05 billion in Adjusted EBITDA, implying continued growth but lower margins. The Board approved an 11% increase in the annual cash dividend to $0.80 per share, or $0.20 quarterly, payable June 15, 2026.
