Scott Barbour, President and Chief Executive Officer of ADS commented, "In the third quarter, we saw net sales return to growth as the Infiltrator business and Allied products portfolio continued to outperform expectations. Despite ongoing headwinds from higher interest rates, credit tightening and economic uncertainty, volume increased in the quarter, primarily driven by stronger demand in the infrastructure, residential and agriculture markets. Importantly, our business model continues to demonstrate resilience, as evidenced by the record Adjusted EBITDA margin of 30.8% achieved during the third quarter, a 490-basis points improvement from the prior year. The margin performance this quarter benefited from sales mix, effective management of price/cost and the contributions of past investments in the business including new equipment, automation and tooling, which enhance the operational efficiency of our entire operation."

"The secular trend of larger-scale and more frequent water-related climate events continues to drive demand for the sustainable water management solutions ADS and Infiltrator provide. As part of our ongoing commitment to manage and protect water, the world’s most precious natural resource, Infiltrator recently launched the ECOPOD-NX. This product is the next generation of advanced wastewater treatment technology designed for higher nitrogen reduction. Many geographies are updating regulations to require higher levels of nitrogen removal, and the ECOPOD-NX leverages Infiltrator's leading market knowledge and distribution relationships. In addition, we established a strategic partnership with Rainwater Management Solutions, a provider of cutting-edge rainwater harvesting and reuse systems. These two programs demonstrate ADS' strategic commitment to improving the environment and communities through our water management solutions."

Barbour concluded, "As we move into the final quarter of this fiscal year, we updated our guidance ranges to reflect the improved demand environment and increased profitability. Outlook for the non-residential end market remains uncertain due to high interest rates and tight credit standards. We will continue to focus on delivering exceptional service to our customers and pursuing profitable growth through attractive products, markets and partnerships, while at the same time continuing to invest capital and resources at both ADS and Infiltrator to drive growth and profitability."

Third Quarter Fiscal 2024 Results

Net sales increased $7.2 million, or 1.1%, to $662.4 million, as compared to $655.2 million in the prior year quarter. Domestic pipe sales decreased $18.8 million, or 5.2%, to $346.1 million. Domestic allied products & other sales increased $8.7 million, or 5.9%, to $156.4 million. Infiltrator sales increased $14.9 million, or 16.8%, to $103.9 million. The overall increase in domestic net sales was primarily driven by the improvement in the U.S. residential and infrastructure construction end markets. International sales increased $2.4 million, or 4.4%, to $56.0 million.

Gross profit increased $35.9 million, or 16.0%, to $259.8 million as compared to $223.9 million in the prior year. The increase in gross profit is primarily due to favorable material cost and sales mix.

Net income per diluted share increased $0.35, or 35.4%, to $1.34, as compared to $0.99 per share in the prior year quarter, primarily due to the factors mentioned above.

Adjusted EBITDA (Non-GAAP) increased $34.5 million, or 20.3%, to $204.2 million, as compared to $169.7 million in the prior year, primarily due to the factors mentioned above. As a percentage of net sales, Adjusted EBITDA was 30.8% as compared to 25.9% 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.”

Year-to-Date Fiscal 2023 Results

Net sales decreased $232.9 million, or 9.5%, to $2,220.6 million, as compared to $2,453.6 million in the prior year quarter. Domestic pipe sales decreased $189.7 million, or 13.8%, to $1,180.3 million. Domestic allied products & other sales decreased $22.7 million, or 4.2%, to $520.7 million. Infiltrator sales decreased $11.6 million, or 3.3%, to $343.0 million. The decrease in domestic net sales was driven by lower demand in the U.S. construction and agriculture end markets. International sales decreased $8.8 million, or 4.7%, to $176.6 million.

Gross profit decreased $2.0 million, or 0.2%, to $894.0 million as compared to $896.0 million in the prior year. The decrease in gross profit is primarily due to the decrease in volume and unfavorable fixed cost absorption, partially offset by favorable material costs.

Net income per diluted share increased $0.22, or 4.4%, to $5.24, as compared to $5.02 per share in the prior year quarter. Results for fiscal 2024 include a $14.9 million gain on the sale of assets, which after considering the income tax impact of this gain impacted net income per diluted share by $0.13.

Adjusted EBITDA (Non-GAAP) decreased $0.2 million, or 0.0%, to $731.8 million, as compared to $732.0 million in the prior year, primarily due to the factors mentioned above. As a percentage of net sales, Adjusted EBITDA was 33.0% as compared to 29.8% in the prior year.

Balance Sheet and Liquidity

Net cash provided by operating activities was $700.3 million, as compared to $660.4 million in the prior year.

In the nine months ended December 31, 2023, the Company repurchased 1.6 million shares of its common stock for a total cost of $178.2 million. As of December 31, 2023, approximately $245.6 million of common stock may be repurchased under the Company's existing share repurchase authorization.

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 below reconciliations 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 below 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 expenses, impairment charges and transaction costs. Adjusted Earnings per Share are measures 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.
