Rhea-AI Filing Summary

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.

Insights

ADS delivered healthy growth, strong cash generation and a higher dividend, but with rising costs and leverage.

Advanced Drainage Systems grew fiscal 2026 net sales 5.0% to $3,050.4 million, while Adjusted EBITDA rose 8.3% to $962.9 million, expanding margin to 31.6%. Growth was driven by higher-margin Infiltrator and Allied products and the NDS acquisition, even as GAAP net income declined modestly from acquisition, restructuring and realignment expenses.

Cash generation was a highlight: operating cash flow reached $819.1 million and free cash flow $569.3 million. The company returned $155.4 million to shareholders via buybacks and dividends and still ended with total liquidity of $962.9 million. Net debt increased to $1,548.9 million, lifting the leverage ratio to 1.6x as of March 31, 2026, reflecting the NDS acquisition and refinancing activity.

Management’s fiscal 2027 outlook guides net sales to $3.35–$3.55 billion and Adjusted EBITDA to $1.0–$1.05 billion, implying continued growth but a margin range of 29.6%–29.9%, below fiscal 2026. The Board approved an 11% increase in the annual dividend to $0.80 per share, signaling confidence in cash flows. Subsequent filings and quarterly updates will show how integration of NDS and end-market demand, particularly in non-residential and agriculture, track against these targets.

Adjusted EBITDA financial
"Adjusted EBITDA (Non-GAAP) increased $73.7 million, or 8.3%, to $962.9 million"
Adjusted EBITDA is a way companies measure how much money they make from their core operations, like running a business, by removing certain costs or income that aren’t part of regular business activities. It helps investors see how well a company is doing without distractions from unusual expenses or gains, making it easier to compare companies or track performance over time.
Free cash flow financial
"Free cash flow (Non-GAAP) was $569.3 million, as compared to $368.5 million"
Free cash flow is the amount of money a company has left over after paying all its expenses and investing in its business, like buying equipment or updating facilities. It shows how much cash is available to reward shareholders, pay down debt, or save for future growth. This helps investors understand if a company is financially healthy and able to grow.
Adjusted Earnings per Share from Continuing Operations financial
"Adjusted EPS from continuing operations increased $0.38, or 6.5%, to $6.27"
leverage ratio financial
"As of March 31, 2026, the Company’s leverage ratio was 1.6 times"
Leverage ratio measures how much a company relies on borrowed money compared with its own funds or assets, typically expressed as debt relative to equity or total assets. Like a homeowner with a mortgage, higher leverage can amplify returns when business is strong but also raises the chance of big losses or default if revenue falls, so investors use it to judge financial risk and resilience.
Non-GAAP financial measures financial
"This press release includes references to Adjusted EBITDA, Organic Net Sales, Free Cash Flow and Adjusted Earnings per Share from Continuing Operations, non-GAAP financial measures."
Non-GAAP financial measures are numbers companies use to show their financial performance that exclude certain expenses or income. They help investors see how the company might perform without one-time costs or other unusual items, giving a different perspective from official reports. However, since they can be adjusted, they don’t always tell the full story and should be looked at alongside standard financial figures.
National Diversified Sales (NDS) financial
"Stormwater sales include $48.8 million of revenue from the acquisition of National Diversified Sales ("NDS")."
Q4 2026 Net Sales $676.8 million +9.9% year over year
Q4 2026 Adjusted EBITDA $188.0 million +6.4% year over year
FY 2026 Net Sales $3,050.4 million +5.0% year over year
FY 2026 Adjusted EBITDA $962.9 million +8.3% year over year
FY 2026 Adjusted EPS $6.27 +6.5% year over year
Guidance

For fiscal 2027, the company targets net sales of $3.35–$3.55 billion and Adjusted EBITDA of $1.0–$1.05 billion, with an Adjusted EBITDA margin of 29.6%–29.9%.

ADVANCED DRAINAGE SYSTEMS ANNOUNCES FOURTH QUARTER AND
FISCAL YEAR 2026 RESULTS

Closed NDS acquisition
Fourth quarter net sales increased 9.9% to $676.8 million
Fourth quarter organic sales increased 2.0%
Generated $819.1 million in cash from operations; returned $155.4 million to shareholders in Fiscal Year 2026

HILLIARD, Ohio – (May 21, 2026) – Advanced Drainage Systems, Inc. (NYSE: WMS) ("ADS" or the "Company"), a leading provider of innovative water management solutions in the stormwater and wastewater industries today announced financial results for the fourth quarter and fiscal year ended March 31, 2026.

Scott Barbour, President and Chief Executive Officer of ADS commented, "In the fourth quarter, net sales increased 10% overall, driven by strong growth in Allied products as well as the contribution from the NDS acquisition, which we closed in the quarter. We continue to focus on material conversion, new product introductions, customer programs and acquisitions to drive growth in the challenging demand environment. Adjusted EBITDA also increased 6%, driven by favorable volume and price/cost."

"In Fiscal 2026, net sales increased 5% as we executed our differentiated growth strategy to drive above market performance through material conversion, product innovation and acquisitions in the stormwater and wastewater markets. Importantly, sales in our higher margin products, Infiltrator and Allied products, increased 14% and 13%, respectively, and these product categories represented a collective 48% of Fiscal 2026 revenue. The resiliency of our model demonstrated by this year's 31.6% Adjusted EBITDA margin is due in part to our strategy to grow these more profitable products to be a higher mix of the overall sales."

"Turning to Fiscal 2027, we are cautious on the demand outlook due to the geopolitical uncertainty, elevated interest rates and resulting economic uncertainty. Non-residential construction activity continues to benefit from large projects, though residential construction activity has slowed. We have good line of sight into our costs, and we are working to offset inflationary pressure on a dollar-for-dollar basis through pricing actions as well as by utilizing our North American leading recycling capabilities to pivot to lower-cost material. We are confident in our ability to grow and increase market share during this period of market uncertainty, supported by our national reach and industry-leading product portfolio, as we focus on growing geographies and segments of the construction market, such as data centers."

Barbour concluded, "Long term, we will continue to grow our resilient platform with strong cash generation to enable disciplined capital allocation that drives shareholder returns."

Fourth Quarter Fiscal 2026 Results
Net sales increased $61.0 million, or 9.9%, to $676.8 million, as compared to $615.8 million in the prior year quarter. Stormwater sales increased $56.0 million, or 11.7%, to $534.7 million, as compared to $478.8 million in the prior year quarter. Stormwater sales include $48.8 million of revenue from the acquisition of National Diversified Sales ("NDS"). Stormwater sales increased 2% on an organic basis. Wastewater sales increased $5.0 million, or 3.7%, to $142.0 million, as compared to $137.0 million in the prior year period.

Gross profit increased $11.4 million, or 5.0%, to $237.7 million as compared to $226.3 million in the prior year. The increase in gross profit is primarily driven by volume growth, favorable price/cost, and favorable mix of Allied products and Infiltrator.

Selling, general and administrative expenses increased $46.2 million, or 50.5% to $137.6 million, as compared to $91.4 million in the prior year. As a percentage of sales, selling, general and administrative expense was 20.3% as compared to 14.8% in the prior year. The increase was primarily driven by the acquisition of NDS and associated transaction costs.

Net income from continuing operations decreased $41.6 million, or 54.1%, to $35.2 million, as compared to $76.8 million in the prior year. Diluted Earnings Per Share ("EPS") from continuing operations decreased $0.56, or 56.6%, to $0.43, as compared to $0.99 per share in the prior year quarter. The decrease is primarily due to acquisition related costs as well as restructuring and realignment expenses. Adjusted EPS from continuing operations increased $0.04, or 3.9%, to $1.07, as compared to $1.03 in the prior year period.

Adjusted EBITDA (Non-GAAP) increased $11.3 million, or 6.4%, to $188.0 million, as compared to $176.7 million in the prior year, primarily due to the factors mentioned above. As a percentage of net sales, Adjusted EBITDA was 27.8% as compared to 28.7% in the prior year.

Segment sales results are based on Net sales to external customers. Reconciliations of GAAP to Non-GAAP financial measures for Adjusted EBITDA, Free Cash Flow and Adjusted Earnings per Share have been provided in the financial statement tables included in this press release. An explanation of these measures is also included below under the heading "Non-GAAP Financial Measures."

Gross profit increased $73.1 million, or 6.7%, to $1,167.4 million as compared to $1,094.2 million in the prior year. The increase in gross profit is primarily driven by favorable volume, price/cost and mix of construction market and Infiltrator sales, partially offset by unfavorable fixed cost absorption as well as the mix impact from acquisitions.

Selling, general and administrative expenses increased $89.2 million, or 23.4% to $469.5 million, as compared to $380.4 million. As a percentage of sales, selling, general and administrative expense was 15.4% as compared to 13.1% in the prior year. The increase was primarily driven by the acquisitions of Orenco and NDS, as well as transaction costs associated with the acquisition of NDS.

Net income from continuing operations decreased $22.7 million, or 5.0%, to $429.9 million, as compared to $452.6 million in the prior year. Diluted EPS from continuing operations decreased $0.31, or 5.4%, to $5.45, as compared to $5.76 per share in the prior year quarter. The decrease is primarily due to acquisition related costs as well as restructuring and realignment expenses. Adjusted EPS from continuing operations increased $0.38, or 6.5%, to $6.27, as compared to $5.89 in the prior year period.

Adjusted EBITDA (Non-GAAP) increased $73.7 million, or 8.3%, to $962.9 million, as compared to $889.2 million in the prior year, primarily due to the factors mentioned above. As a percentage of net sales, Adjusted EBITDA was 31.6% as compared to 30.6% in the prior year.

Selected Financial Data
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, Organic Net Sales, Free Cash Flow and Adjusted Earnings per Share from Continuing Operations, 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 below reconciliations of Adjusted EBITDA to net income.

Organic Net Sales is a non-GAAP financial measure that represents net sales excluding the impact of acquisitions and is intended to provide a meaningful comparison of sales growth attributable to underlying volume and pricing changes in the Company’s continuing operations.
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 below a reconciliation of cash flow from operating activities to Free Cash Flow.
Adjusted Earnings per Share from Continuing Operations excludes (gains) losses on disposals of assets or business, restructuring expenses, impairment charges, inventory step up related to the acquisition of NDS and transaction costs. Adjusted Earnings per Share from Continuing Operations 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.

Forward Looking Statements and Non-GAAP Financial Metrics 3 Forward Looking Statements Certain statements in this press release may be deemed to be forward-looking statements. These statements are not historical facts but rather are based on the Company’s current expectations, estimates and projections regarding the Company’s business, operations and other factors relating thereto. Words such as “may,” “will,” “could,” “would,” “should,” “anticipate,” “predict,” “potential,” “continue,” “expects,” “intends,” “plans,” “projects,” “believes,” “estimates,” “confident” and similar expressions are used to identify these forward-looking statements. Factors that could cause actual results to differ from those reflected in forward-looking statements relating to our operations and business include: fluctuations in the price and availability of resins and other raw materials, new tariff and international trade policies, and our ability to pass any increased costs of raw materials and tariffs on to our customers in a timely manner; disruption or volatility in general business, political and economic conditions in the markets in which we operate; cyclicality and seasonality of the non-residential and residential construction markets and infrastructure spending; the risks of increasing competition in our existing and future markets; uncertainties surrounding the integration and realization of anticipated benefits of acquisitions or doing so within the intended timeframe, including our ability to successfully integrate NDS into our business; risks that the acquisition of NDS may involve unexpected costs, liabilities, risks that the cost savings and synergies from the acquisition of NDS may not be fully realized; the effect of weather or seasonality; the loss of any of our significant customers; the risks of doing business internationally; the risks of conducting a portion of our operations through joint ventures; our ability to expand into new geographic or product markets; the risk associated with manufacturing processes; the effects of global climate change and any related regulatory responses; our ability to protect against cybersecurity incidents and disruptions or failures of our IT systems; our ability to assess and monitor the effects of artificial intelligence, machine learning, robotics and blockchain or other new approaches to data mining on our business and operations; our ability to manage our supply purchasing and customer credit policies; our ability to control labor costs and to attract, train and retain highly qualified employees and key personnel; our ability to protect our intellectual property rights; changes in laws and regulations, including environmental laws and regulations; our ability to appropriately address any environmental, social or governance concerns that may arise from our activities; the risks associated with our current levels of indebtedness, including borrowings under our existing credit agreement and outstanding indebtedness under our existing senior notes; and other risks and uncertainties described in the Company’s filings with the SEC. New risks and uncertainties emerge from time to time and it is not possible for the Company to predict all risks and uncertainties that could have an impact on the forward-looking statements contained in this press release. In light of the significant uncertainties inherent in the forward-looking information included herein, the inclusion of such information should not be regarded as a representation by the Company or any other person that the Company’s expectations, objectives or plans will be achieved in the timeframe anticipated or at all. Investors are cautioned not to place undue reliance on the Company’s forward-looking statements and the Company undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law. Non-GAAP Financial Measures This presentation includes references to Adjusted EBITDA and Free Cash Flow, 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.

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.

What guidance did Advanced Drainage Systems provide for fiscal 2027?

Advanced Drainage Systems expects fiscal 2027 net sales between $3.35 billion and $3.55 billion and Adjusted EBITDA between $1.0 billion and $1.05 billion. This outlook implies continued growth but a lower Adjusted EBITDA margin range of 29.6%–29.9% versus 31.6% in fiscal 2026.
