ADVANCED DRAINAGE SYSTEMS ANNOUNCES FIRST QUARTER
FISCAL 2026 RESULTS
HILLIARD, Ohio – (August 7, 2025) – Advanced Drainage Systems, Inc. (NYSE: WMS) (“ADS” or the “Company”), a leading provider of innovative water management solutions in the stormwater and onsite wastewater industries today announced financial results for the fiscal first quarter ended June 30, 2025.
First Quarter Fiscal 2026 Results
Net sales increased $14.5 million or 1.8% to $829.9 million
Net income decreased $18.2 million or 11.2% to $144.1 million
Net income per diluted share decreased $0.22 or 10.7% to $1.84
Adjusted EBITDA (Non-GAAP) increased $2.7 million or 1.0% to $278.2 million
Adjusted Earnings per share (Non-GAAP) decreased $0.11 or 5.3% to $1.95
Scott Barbour, President and Chief Executive Officer of ADS commented, "We delivered strong results in the fiscal first quarter, with Adjusted EBITDA margin of 33.5%. Wet weather in May and June continued to delay project installations, and elevated interest rates remain a headwind. However, the ADS and Infiltrator teams executed well and remain focused on driving profitable growth and operational performance in a challenging macroeconomic environment."
"Investments in engineering, customer service, capacity, productivity and logistics all support long-term growth and profitability. We continue to develop innovative new product offerings, such as the Arcadia stormwater separator formally launched in the quarter, and Infiltrator continues to make meaningful progress in scaling our advanced treatment platform solutions at Orenco. Additionally, we acquired River Valley Pipe early in the quarter, which strengthened our presence in key geographies and provides future operational flexibility. Across the board, we are focused on the levers we can control, including managing costs, accelerating new product introductions, and most importantly, executing customer service improvements."
Barbour concluded, "The highly attractive water segments we operate in are supported by secular tailwinds and the growing awareness of the value of proper stormwater and onsite wastewater management, ultimately driving long-term demand for the Company's products. While cyclical, short-term pressures exist, the fundamentals of our business are resilient and we are well positioned to continue capitalizing on our value proposition, driving market conversion, and accelerating growth in more profitable areas such as Infiltrator and Allied products."
First Quarter Fiscal 2026 Results
Net sales increased $14.5 million, or 1.8%, to $829.9 million, as compared to $815.3 million in the prior year quarter. Domestic pipe sales decreased $10.9 million, or 2.5%, to $415.5 million. Domestic allied products & other sales increased $3.6 million, or 1.9%, to $187.5 million. Infiltrator sales increased $31.1 million, or 21.1%, to $178.4 million, primarily due to the acquisition of Orenco Systems, Inc. ("Orenco"). Infiltrator organic revenue increased 0.7%. The overall increase in domestic net sales was primarily driven by acquisitions, as well as growth in the non-residential and residential construction end markets. International sales decreased $9.2 million, or 16.0%, to $48.5 million.
Gross profit decreased $2.0 million, or 0.6%, to $330.4 million as compared to $332.5 million in the prior year. The decrease in gross profit is primarily driven by unfavorable fixed cost absorption as well as the mix impact from the inclusion of Orenco. This unfavorability was partially offset by favorable price/cost and mix of construction market and Infiltrator sales.

Selling, general and administrative expenses increased $9.9 million, or 10.5% to $104.0 million, as compared to $94.1 million. As a percentage of sales, selling, general and administrative expense was 12.5% as compared to 11.5% in the prior year, primarily driven by the acquisition of Orenco.

Net income per diluted share decreased $0.22, or 10.7%, to $1.84, as compared to $2.06 per share in the prior year quarter, primarily due to the factors mentioned above.
Adjusted EBITDA (Non-GAAP) increased $2.7 million, or 1.0%, to $278.2 million, as compared to $275.5 million in the prior year, primarily due to the factors mentioned above. As a percentage of net sales, Adjusted EBITDA was 33.5% as compared to 33.8% in the prior year.

Non-GAAP Financial Measures
This press release contains financial information determined by methods other than in accordance with accounting principles generally accepted in the United States of America (“GAAP”). ADS management uses non-GAAP measures in its analysis of the Company’s performance. Investors are encouraged to review the reconciliation of non-GAAP financial measures to the comparable GAAP results available in the accompanying tables.
Reconciliation of Non-GAAP Financial Measures
This press release includes references to Adjusted EBITDA, Free Cash Flow and Adjusted Earnings per Share, non-GAAP financial measures. These non-GAAP financial measures are used in addition to and in conjunction with results presented in accordance with GAAP. These measures are not intended to be substitutes for those reported in accordance with GAAP. Adjusted EBITDA and Free Cash Flow may be different from non-GAAP financial measures used by other companies, even when similar terms are used to identify such measures.
EBITDA and Adjusted EBITDA are non-GAAP financial measures that comprise net income before interest, income taxes, depreciation and amortization, stock-based compensation, non-cash charges and certain other expenses. The Company’s definition of Adjusted EBITDA may differ from similar measures used by other companies, even when similar terms are used to identify such measures. Adjusted EBITDA is a key metric used by management and the Company’s board of directors to assess financial performance and evaluate the effectiveness of the Company’s business strategies. Accordingly, management believes that Adjusted EBITDA provides useful information to investors and others in understanding and evaluating our operating results in the same manner as the Company’s management and board of directors. In order to provide investors with a meaningful reconciliation, the Company has provided a reconciliation of Adjusted EBITDA to net income.
Free Cash Flow is a non-GAAP financial measure that comprises cash flow from operating activities less capital expenditures. Free Cash Flow is a measure used by management and the Company’s board of directors to assess the Company’s ability to generate cash.  Accordingly, management believes that Free Cash Flow provides useful information to investors and others in understanding and evaluating our ability to generate cash flow from operations after capital expenditures. In order to provide investors with a meaningful reconciliation, the Company has provided a reconciliation of cash flow from operating activities to Free Cash Flow.
Adjusted Earnings per Share excludes (gains) losses on disposals of assets or business, restructuring and realignment expenses, impairment charges and transaction costs. Adjusted Earnings per Share is a measure used by management and may be useful for investors to evaluate the Company's operational performance.
The following tables present a reconciliation of EBITDA and Adjusted EBITDA to Net Income, Free Cash Flow to Cash Flow from Operating Activities, and Adjusted Earnings per Share to Diluted Earnings per Share, the most comparable GAAP measures, for each of the periods indicated.
