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, 2024 was derived from audited financial statements included in the Annual Report on Form 10-K for the year ended March 31, 2024 (“Fiscal 2024 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 30, 2024, the results of operations for the three and six months ended September 30, 2024 and cash flows for the six months ended September 30, 2024. 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 2024 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 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
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.
- 10 -

Table of Contents
Disaggregation of Income Statement Expenses - In November 2024, the FASB issued new guidance requiring additional disclosure of the nature of certain expenses included in the income statement as well as disclosure of selling expenses. The requirements will be applied prospectively with the option for retrospective application. The new standard is effective for annual reporting periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027. The Company is currently evaluating the impact of this standard on the Consolidated Financial Statements.

Among other things, the Second Amendment (i) amended the Base Credit Agreement by increasing the Revolving Credit Facility (the “Amended Revolving Credit Facility”) from $350 million to $600 million (including an increase of the sub-limit for the swing-line sub-facility from $50 million to $60 million), (ii) extended the maturity date of the Revolving Credit Facility to May 26, 2027, (iii) revised the “applicable margin” to provide an additional step-down to 175 basis points (for Term Benchmark based loans) and 75 basis points (for base rate loans) in the event the consolidated senior secured net leverage ratio is less than 2.00 to 1.00, and (iv) reset the “incremental amount” and the investment basket in non-guarantors and joint ventures. The Second Amendment also revised the reference interest rate from LIBOR to SOFR for both the Amended Revolving Credit Facility and the Term Loan Facility. Letters of credit outstanding at September 30, 2024 and March 31, 2024 amounted to $10.5 million and $11.2 million, respectively, and reduced the availability of the Revolving Credit Facility.
Senior Notes due 2027 - On September 23, 2019, the Company issued $350.0 million aggregate principal amount of 5.0% Senior Notes due 2027 (the “2027 Notes”) pursuant to an Indenture, dated September 23, 2019 (the “2027 Indenture”), among the Company, the guarantors party thereto (the “Guarantors”) and U.S. Bank National Association, as Trustee (the “Trustee”).

Equipment Financing - The assets under the Equipment Financing acquired are titled to the Company and included in Property, plant and equipment, net on the Company's Condensed Consolidated Balance Sheet. The equipment financing has an initial term of between 12 and 84 months, based on the life of the equipment, and bears a weighted average interest rate of 1.7% as of September 30, 2024. The current portion of the equipment financing is $4.1 million, and the long-term portion is $4.1 million at September 30, 2024.
Valuation of Debt - The carrying amounts of current financial assets and liabilities approximate fair value because of the immediate or short-term maturity of these items. The following table presents the carrying and fair value of the Company’s 2027 Notes, 2030 Notes and Equipment Financing for the periods presented:
 September 30, 2024 March 31, 2024

period. The categorization of the framework used to evaluate the 2027 Notes, 2030 Notes and Equipment Financing are considered Level 2.

The Company records a liability when a loss is considered probable, and the amount can be reasonably estimated.
9.INCOME TAXES

11.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.

Our consolidated Net sales for the three months ended September 30, 2024 increased by $2.4 million, or 0.3%, compared to the same period in fiscal 2024. The overall increase in domestic net sales was primarily driven by demand in the residential and infrastructure end markets. Net sales for Infiltrator were also driven by improved price/mix, while the

(Amounts in thousands)20242023
Selling, general and administrative expenses$188,184 $178,236

Selling, general and administrative expenses for six months ended September 30, 2024 increased $9.9 million from the same period in fiscal 2024 and as a percentage of net sales, increased by 0.4%. This increase is primarily due to higher commissions from the increase in volume, as well as continued investments in talent to support strategic areas such as engineering and product development.
Loss (gain) on disposal of assets and costs from exit and disposal activities - The gain on disposal in fiscal 2024 was due to the sale of Spartan Concrete, Inc.
Interest expense - Interest expense increased $2.3 million in the six months ended September 30, 2024 compared to the same period in the previous fiscal year. The increase was primarily due to increased interest rates.
Interest income and other, net - Interest income and other, net increased by $3.0 million for the six months ended September 30, 2024 compared to the same period in the previous fiscal year primarily due to increased cash.
Income tax expense - The following table presents the effective tax rates for the six months ended September 30, 2024 and 2023.
 Six Months Ended September 30,
 2024 2023
Effective tax rate23.8 %25.0 %
The change in the effective tax rate for the six months ended September 30, 2024 was primarily related to the decrease in state and local income taxes and the increase of the discrete income tax benefit related to the stock-based compensation windfall. See “Note 9. 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 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 to cash provided by operating activities, the most comparable GAAP measure, for each of the periods presented:

Revolver available liquidity$589,550 
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.
As of September 30, 2024, we had $23.5 million in cash that was held by our foreign subsidiaries, including $14.7 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.
Working Capital and Cash Flows
As of September 30, 2024, we had $1,202.6 million in liquidity, including $613.0 million of cash and $589.6 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 $1,024.6 million as of September 30, 2024, from $860.3 million as of March 31, 2024. The increase in working capital is primarily due to an increase in cash, accounts receivable and inventory due to seasonality offset by changes in accounts payable due to the timing of payments.

Net cash used in investing activities(111,542)(62,200)
Net cash used in financing activities(114,640)(143,386)
Operating Cash Flows - Cash flows from operating activities decreased $108.5 million during the six months ended September 30, 2024 primarily driven by investment in inventory.
Investing Cash Flows - Cash flows used in investing activities during the six months ended September 30, 2024 increased by $49.3 million compared to the same period in fiscal 2024. The increase in cash used in investing activities was primarily due to increased capital expenditures in fiscal 2025 and the sale of Spartan Concrete in fiscal 2024.
Capital expenditures totaled $112.2 million and $82.6 million for the six months ended September 30, 2024 and 2023, respectively. Our capital expenditures for the six months ended September 30, 2024 were used primarily to support facility expansions, equipment replacements and technology improvement initiatives. We also acquired $48.5 million of property, plant and equipment under finance leases, which includes transportation equipment to update our fleet of trucks and trailers.
We currently anticipate that we will make capital expenditures of approximately $250 million in fiscal year 2025, including approximately $120 million of open orders as of September 30, 2024. Such capital expenditures are expected to be financed using funds generated by operations.

Financing Cash Flows - During the six months ended September 30, 2024, cash used in financing activities included the repurchase of common stock of $69.9 million, $24.9 million of dividend payments, $11.8 million of payments of finance lease obligations and $10.6 million for shares withheld for tax purposes.
During the six months ended September 30, 2023, cash used in financing activities included the repurchase of common stock of $101.6 million, $22.2 million of dividend payments, and $8.8 million for shares withheld for tax purposes.
Financing Transactions - There have been no changes in our debt disclosures from those disclosed in “Liquidity and Capital Resources” in our Fiscal 2024 Form 10-K. We are in compliance with our debt covenants as of September 30, 2024.
Off-Balance Sheet Arrangements
Excluding the guarantees of 50% of certain debt of our unconsolidated South American Joint Venture as further discussed in “Note 6. Related Party Transactions” to the Condensed Consolidated Financial Statements, we do not have any other off-balance sheet arrangements. As of September 30, 2024, our South American Joint Venture had no 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 2024 Form 10-K, except as disclosed in “Note 1. Background and Summary of Significant Accounting Policies.”
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 2024 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 $4.1 million based on our borrowings as of September 30, 2024. 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 $10.1 million, for the twelve months ended September 30, 2024.
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 30, 2024 that has materially affected, or is reasonably likely to materially affect, internal control over financial reporting.
