ADVANCED DRAINAGE SYSTEMS, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

1.BACKGROUND AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Description of Business - Advanced Drainage Systems, Inc., incorporated in Delaware, and its subsidiaries (collectively referred to as “ADS” or the “Company”) designs, manufactures and markets innovative water management solutions in the stormwater and onsite septic wastewater industries, providing superior drainage solutions for use in the construction and agriculture marketplace. ADS’s products are used across a broad range of end markets and applications, including non-residential, infrastructure and agriculture applications.

The Company is managed and reports results of operations in three reportable segments: Pipe, Infiltrator Water Technologies Ultimate Holdings, Inc ("“Infiltrator"”) and International. The Company also reports the results of its Allied Products and all other business segments as Allied Products and Other.

Historically, sales of the Company’s products have been higher in the first and second quarters of each fiscal year due to favorable weather and longer daylight conditions accelerating construction activity during these periods. Seasonal variations in operating results may also be impacted by inclement weather conditions, such as cold or wet weather, which can delay projects.

Basis of Presentation - The Company prepares its Condensed Consolidated Financial Statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The Condensed Consolidated Balance Sheet as of March 31, 2023 was derived from audited financial statements included in the Annual Report on Form 10-K for the year ended March 31, 2023 (“Fiscal 2023 Form 10-K”). The accompanying unaudited Condensed Consolidated Financial Statements contain all adjustments, of a normal recurring nature, necessary to present fairly its financial position as of ~~September~~December 3031, 2023 and the results of operations for the three and ~~six~~nine months ended ~~September~~December 3031, 2023 and cash flows for the ~~six~~nine months ended ~~September~~December 3031, 2023. The interim Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements, including the notes thereto, filed in the Company’s Fiscal 2023 Form 10-K.

Principles of Consolidation - The Condensed Consolidated Financial Statements include the Company, its wholly-owned subsidiaries, its majority-owned subsidiaries and variable interest entities (“VIEs”) of which the Company is the primary beneficiary. The Company uses the equity method of accounting for equity investments where it exercises significant influence but does not hold a controlling financial interest. Such investments are recorded in Other assets in the Condensed Consolidated Balance Sheets and the related equity earnings from these investments are included in Equity in net income of unconsolidated affiliates in the Condensed Consolidated Statements of Operations. All intercompany balances and transactions have been eliminated in consolidation.

Recent Accounting Guidance - There have been no new accounting pronouncements issued or adopted since the filing of the Fiscal 2023 Form 10-K that have significance, or potential significance, to the Condensed Consolidated Financial Statements.

Improvements to Reportable Segment Disclosures - In November 2023, the Financial Accounting Standards Board (“FASB”) issued an accounting standards update (“ASU”) to amend ASC 280, Segment Reporting to enhance segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. In addition, the amendments enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, provide new segment disclosure requirements for entities with a single reportable segment, and contain other disclosure requirements. The amendments are effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. The amendments must be applied retrospectively to all periods presented in the financial statements. The Company is currently evaluating the impact of this standard on the Consolidated Financial Statements.

Improvements to Income Tax Disclosures - In December 2023, the FASB issued an ASU to amend ASC 740, Income Taxes to enhance the transparency and usefulness of income tax disclosures, primarily related to the rate reconciliation and income taxes paid information. The amendments may be applied prospectively or retrospectively and are effective for fiscal years beginning after December 15, 2024. The Company is currently evaluating the impact of this standard on the Consolidated Financial Statements.

Except for the pronouncements described above, there have been no new accounting pronouncements issued or adopted since the filing of the Fiscal 2023 Form 10-K that have significance, or potential significance, to the Consolidated Financial Statements.

2.GAIN ON DISPOSAL OF ASSETS AND COSTS FROM EXIT AND DISPOSAL ACTIVITIES

On April 14, 2023, the Company completed its divestiture of substantially all of the assets of Spartan Concrete, Inc. to a third party purchaser for consideration of $20.0 million. The Company recognized a gain on the sale of $14.9 million in the Condensed Consolidated Statements of Operations. Prior to the divestiture, the Company recorded the results of operations in Allied & Other.

3.REVENUE RECOGNITION

Revenue Disaggregation - The Company disaggregates net sales by Domestic, International and Infiltrator and further disaggregates Domestic and International by product type, consistent with its reportable segment disclosure. This disaggregation level best depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors. Refer to “Note 12. Business Segments Information” for the Company’s disaggregation of Net sales by reportable segment.

12.BUSINESS SEGMENTS INFORMATION

The Company operates its business in three distinct reportable segments: “Pipe”, “International” and “Infiltrator.” “Allied Products & Other” represents the Company’s Allied Products and all other business segments. The Chief Operating Decision Maker (the “CODM”) evaluates segment reporting based on Net Sales and Segment Adjusted Gross Profit. The Company calculated Segment Adjusted Gross Profit as Net sales less Costs of goods sold, depreciation and amortization, stock-based compensation and non-cash charges. A measure of assets is not applicable, as segment assets are not regularly reviewed by the CODM for evaluating performance or allocating resources.

The following table sets forth reportable segment information with respect to the amount of Net sales contributed by each class of similar products for the periods presented:

Effective tax rate	2524.03	%	23.24	%

The change in the effective tax rate for the ~~six~~nine months ended ~~September~~December 3031, 2023 was primarily related to the decrease of the discrete income tax benefit related to the stock-based compensation windfall. See “Note 10. Income Taxes” for additional information.

Adjusted EBITDA and Adjusted EBITDA Margin - Adjusted EBITDA and Adjusted EBITDA Margin, which are non-GAAP financial measures, have been presented in this Form 10-Q as supplemental measures of financial performance that are not required by, or presented in accordance with GAAP and should not be considered as alternatives to net income as measures of financial performance or cash flows from operations or any other performance measure derived in accordance with GAAP. We calculate Adjusted EBITDA as net income ~~(loss)~~ before interest, income taxes, depreciation and amortization, stock-based compensation expense, non-cash charges and certain other expenses. We calculate Adjusted EBITDA Margin as Adjusted EBITDA divided by net sales.

Adjusted EBITDA and Adjusted EBITDA Margin are included in this Form 10-Q because they are key metrics used by management and our board of directors to assess our consolidated financial performance. These non-GAAP financial measures are frequently used by analysts, investors and other interested parties to evaluate companies in our industry. In addition to covenant compliance and executive performance evaluations, we use these non-GAAP financial measures to supplement GAAP measures of performance to evaluate the effectiveness of our consolidated business strategies, to make budgeting decisions and to compare our performance against that of other peer companies using similar measures. We use Adjusted EBITDA Margin to evaluate our ability to generate profitable sales.

Adjusted EBITDA and Adjusted EBITDA Margin contain certain other limitations, including the failure to reflect our cash expenditures, cash requirements for working capital needs, cash expenditures to replace assets being depreciated and amortized and interest expense, or the cash requirements necessary to service interest on principal payments on our indebtedness. In evaluating Adjusted EBITDA and Adjusted EBITDA Margin, you should be aware that in the future we will incur expenses that are the same as or similar to some of the adjustments in this presentation, such as stock-based compensation expense, derivative fair value adjustments, and foreign currency transaction losses. Management compensates for these limitations by relying on our GAAP results and using non-GAAP measures on a supplemental basis.

Liquidity and Capital Resources

Historically we have funded our operations through internally generated cash flow supplemented by debt financings, equity issuance and finance and operating leases. These sources have been sufficient historically to fund our primary liquidity requirements, including working capital, capital expenditures, debt service and dividend payments for our common stock. From time to time, we may explore additional financing methods and other means to raise capital. There can be no assurance that any additional financing will be available to us on acceptable terms or at all.

Free Cash Flow - Free cash flow is a non-GAAP financial measure that comprises cash flow from operations less capital expenditures and is used by management and our Board of Directors to assess our ability to generate cash. Accordingly, free cash flow has been presented as a supplemental measure of liquidity that is not required by, or presented in accordance with GAAP, because 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. Free cash flow is not a GAAP measure of our liquidity and should not be considered as an alternative to cash flow from operating activities as a measure of liquidity or any other liquidity measure derived in accordance with GAAP. Our measure of free cash flow is not necessarily comparable to other similarly titled captions of other companies due to different methods of calculation.

The following table presents a reconciliation of free cash flow ~~from~~to cash provided by operating activities, the most comparable GAAP measure, for each of the periods presented:

	Six Months Ended September 30,
	Nine Months Ended December 31,
(Amounts in thousands)	2023		2022

The following table presents key liquidity metrics utilized by management including the leverage ratio which is calculated as net debt divided by the trailing twelve months Adjusted EBITDA:

(Amounts in thousands)	~~September~~December 3031, 2023
Total debt (debt and finance lease obligations)	$	1,~~320~~324,~~574~~808
Cash	~~470~~560,~~409~~744
Net debt (total debt less cash)	~~850~~764,~~165~~064
Leverage Ratio	1.0.8

The following table summarizes our available liquidity for the period presented:

(Amounts in thousands)	~~September~~December 3031, 2023
Revolver capacity	$	600,000
Less: outstanding borrowings	—
Less: letters of credit	(11,150)
Revolver available liquidity	$	588,850

In addition to the available liquidity above, we have the ability to borrow up to $1.3 billion under our Senior Secured Credit Facility, subject to leverage ratio restrictions.

Working Capital and Cash Flows

As of ~~September~~December 3031, 2023, we had $1,~~059~~149.36 million in liquidity, including $~~470~~560.47 million of cash, $588.9 million in borrowings available under our Revolving Credit Agreement, net of outstanding letters of credit. We believe that our cash on hand, together with the availability of borrowings under our Credit Agreement and other financing arrangements and cash generated from operations, will be sufficient to meet our working capital requirements, anticipated capital expenditures, and scheduled principal and interest payments on our indebtedness for at least the next twelve months.

Working Capital - Working capital increased to $~~804~~829.03 million as of ~~September~~December 3031, 2023, from $638.7 million as of March 31, 2023. The increase in working capital is primarily due to an increase in cash ~~and~~partially ~~increase~~offset by a decrease in accounts receivable and inventory due to seasonality ~~partially~~and ~~offset by~~ an increase in accrued liabilities and accrued taxes due to the timing of payments ~~and a planned decrease in inventory~~.

	Six Months Ended September 30,

(Amounts in thousands)	2023		2022
Net cash provided by operating activities	$	~~458~~700,~~864~~262	$	~~437~~660,~~024~~438

Net cash (used in) provided by financing activities	(~~143~~236,~~386~~436)		~~124~~(78,~~820~~590)

Operating Cash Flows – Cash flows from operating activities increased $2139.8 million during the ~~six~~nine months ended ~~September~~December 3031, 2023 primarily driven by changes in net working capital.

Investing Cash Flows - Cash flows used in investing activities during the ~~six~~nine months ended ~~September~~December 3031, 2023 decreased by $6158.39 million compared to the same period in fiscal 2023. The decrease in cash used in investing activities was primarily due to the acquisition of Cultec, Inc. in fiscal 2023.

Capital expenditures totaled $82136.64 million and $75126.59 million for the ~~six~~nine months ended ~~September~~December 3031, 2023 and 2022, respectively. Our capital expenditures for the ~~six~~nine months ended ~~September~~December 3031, 2023 were used primarily to support facility expansions, equipment replacements and technology improvement initiatives.

We currently anticipate that we will make capital expenditures of approximately $200 ~~to $225~~ million in fiscal year 2024, including approximately $~~115~~125 million of open orders as of ~~September~~December 3031, 2023. Such capital expenditures are expected to be financed using funds generated by operations.

Financing Cash Flows - During the ~~six~~nine months ended ~~September~~December 3031, 2023, cash used in financing activities included the repurchase of common stock of $~~101~~178.62 million, $2233.21 million of dividend payments, and $8.89 million for shares withheld for tax purposes.

Table of Contents

During the ~~six~~nine months ended ~~September~~December 3031, 2022, cash provided by financing activities included the issuance of $500.0 million of 2030 Notes and proceeds of $123.2 million on our revolving credit facilities. Cash used in financing activities during the ~~six~~nine months ended ~~September~~December 3031, 2022 included repurchase of common stock of $375.0 million, payments of $237.5 million on our revolving credit facilities, ~~repurchase~~$30.1 ofmillion ~~common stock~~ of ~~$192.6~~dividend ~~million~~payments, and $2528.57 million offor shares withheld for tax purposes~~, and $20~~.~~4 million of dividend payments.~~

Cash held by Foreign Subsidiaries - As of ~~September~~December 3031, 2023, we had $2039.67 million in cash that was held by our foreign subsidiaries, including $1024.05 million held by our Canadian subsidiaries. We continue to evaluate our strategy regarding foreign cash, but our earnings in foreign subsidiaries still remain indefinitely reinvested, except for Canada. We plan to repatriate earnings from Canada and believe that there will be no additional tax costs associated with the repatriation of such earnings other than any potential non-U.S. withholding taxes.

Financing Transactions - There have been no changes in our debt disclosures from those disclosed in “Liquidity and Capital Resources” in our Fiscal 2023 Form 10-K. We are in compliance with our debt covenants as of ~~September~~December 3031, 2023.

Off-Balance Sheet Arrangements

Excluding the guarantees of 50% of certain debt of our unconsolidated South American Joint Venture as further discussed in “Note 7. Related Party Transactions” to the Condensed Consolidated Financial Statements, we do not have any other off-balance sheet arrangements. As of ~~September~~December 3031, 2023, our South American Joint Venture had approximately ~~$1.4~~no ~~million of~~ outstanding debt subject to our guarantees. We do not believe that this guarantee will have a current or future effect on our financial condition, results of operations, liquidity or capital resources.

Critical Accounting Policies and Estimates

There have been no changes in critical accounting policies from those disclosed in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Fiscal 2023 Form 10-K, except as disclosed in "Note 1. Background and Summary of Significant Accounting Policies.”

Forward-Looking Statements

This Form 10-Q includes forward-looking statements. Some of the forward-looking statements can be identified by the use of terms such as “believes,” “expects,” “may,” “will,” “would,” “should,” “could,” “seeks,” “predict,” “potential,” “continue,” “intends,” “plans,” “projects,” “estimates,” “anticipates” or other comparable terms. These forward-looking statements include all matters that are not related to present facts or current conditions or that are not historical facts. They appear in a number of places throughout this Form 10-Q and include statements regarding our intentions, beliefs or current expectations concerning, among other things, our consolidated results of operations, financial condition, liquidity, prospects, growth strategies, and the industries in which we operate and include, without limitation, statements relating to our future performance.

Forward-looking statements are subject to known and unknown risks and uncertainties, many of which are beyond our control. We caution you that forward-looking statements are not guarantees of future performance and that our actual consolidated results of operations, financial condition, liquidity and industry development may differ materially from those made in or suggested by the forward-looking statements contained in this Form 10-Q. In addition, even if our actual consolidated results of operations, financial condition, liquidity and industry development are consistent with the forward-looking statements contained in this Form 10-Q, those results or developments may not be indicative of results or developments in subsequent periods. A number of important factors could cause actual results to differ materially from those contained in or implied by the forward-looking statements, including those reflected in forward-looking statements relating to our operations and business, the risks and uncertainties discussed in this Form 10-Q (including under the headings “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations”), and those described from time to time in our other filings with the SEC. 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 and our ability to pass any increased costs of raw materials on to our customers in a timely manner;

•disruption or volatility in general business 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;

All forward-looking statements are made only as of the date of this report and we do not undertake any obligation, other than as may be required by law, to update or revise any forward-looking statements to reflect future events or developments. Comparisons of results for current and any prior periods are not intended to express any future trends, or indications of future performance, unless expressed as such, and should only be viewed as historical data.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

We are subject to various market risks, primarily related to changes in interest rates, credit, raw material supply prices and, to a lesser extent, foreign currency exchange rates. Our financial position, results of operations or cash flows may be negatively impacted in the event of adverse movements in the respective market rates or prices in each of these risk categories. Our exposure in each category is limited to those risks that arise in the normal course of business, as we do not engage in speculative, non-operating transactions. Our exposure to market risk has not materially changed from what we previously disclosed in Part II. Item 7A. “Quantitative and Qualitative Disclosures about Market Risk” of our Fiscal 2023 Form 10-K except as disclosed below.

Interest Rate Risk - We are subject to interest rate risk associated with our bank debt. A 1.0% increase in interest rates on our variable-rate debt would increase our annual forecasted interest expense by approximately $4.2 million based on our borrowings as of ~~September~~December 3031, 2023. Assuming the Revolving Credit Facility is fully drawn, each 1.0% increase or decrease in the applicable interest rate would change our interest expense by approximately $10.2 million, for the twelve months ended ~~September~~December 3031, 2023.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures - The Company’s Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”) are responsible for evaluating the effectiveness of our disclosure controls and procedures as defined in the Securities Exchange Act of 1934, as amended (the “Exchange Act”), rules 13a-15(e) and 15d-15(e). The Company’s disclosure controls and procedures are designed to provide reasonable assurance that the information required to be disclosed in the Company’s reports under the Exchange Act, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to management, including the Company’s CEO and CFO, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Based on the evaluation of our disclosure controls and procedures, our CEO and CFO concluded that the Company’s disclosure controls and procedures were effective as of the end of the period covered by this report.

Changes in Internal Control over Financial Reporting - There were no changes in the Company’s internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act that occurred during the three months ended ~~September~~December 3031, 2023 that has materially affected, or is reasonably likely to materially affect, internal control over financial reporting.
