NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

1.	BACKGROUND AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Description of Business - Advanced Drainage Systems, Inc. and subsidiaries (collectively referred to as “ADS” or the “Company”), incorporated in Delaware, designs, manufactures and markets high performance thermoplastic corrugated pipe and related water management products, primarily in North and South America and Europe. ADS’s broad product line includes corrugated high density polyethylene (or “HDPE”) pipe, polypropylene (or “PP”) pipe and related water management products.

The Company is managed based primarily on the geographies in which it operates and reports results of operations in two reportable segments: Domestic and International.

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, 2018 was derived from audited financial statements included in the Annual Report on Form 10-K for the year ended March 31, 2018 (“Fiscal 2018 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, 2018 and the results of operations and cash flows for the three and six months ended September 30, 2018. 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 2018 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 loss of unconsolidated affiliates in the Condensed Consolidated Statements of Operations. All intercompany balances and transactions have been eliminated in consolidation.

Recent Accounting Guidance

Recently Adopted Accounting Guidance

Cloud Computing - On August 29, 2018, the Financial Accounting Standards Board (the “FASB”) issued an accounting standards update (“ASU”) to provide guidance on implementation costs incurred in a cloud computing arrangement (“CCA”) that is a service contract. The ASU, which was released in response to a consensus reached by the EITF at its June 2018 meeting, aligns the accounting for such costs with the guidance on capitalizing costs associated with developing or obtaining internal-use software. Specifically, the ASU includes in its scope implementation costs of a CCA that is a service contract and clarifies that a customer should apply CCA guidance to determine which implementation costs should be capitalized in such a CCA. The Company adopted this update effective July 1, 2018 on a prospective basis. The new standard did not have a material impact on the Condensed Consolidated Financial Statements.

Revenue Recognition - In May 2014, the FASB issued an ASU which amends the guidance for revenue recognition. This amendment contains principles that will require an entity to recognize revenue to depict the transfer of goods and services to customers at an amount that an entity expects to be entitled to in exchange

for goods or services. The amendment sets forth a new revenue recognition model that requires identifying the contract, identifying the performance obligations and recognizing the revenue upon satisfaction of performance obligations. In August 2015, the FASB issued an additional ASU that deferred the effective date of the new revenue standard for public entities to periods beginning after December 15, 2017, with early adoption permitted but not earlier than the original effective date of periods beginning after December 15, 2016. There have also been various additional ASUs issued by the FASB in 2016 that further amend this new revenue standard. The updated standard permits the use of either the retrospective or cumulative effect transition method. The Company adopted these standards on April 1, 2018 using the modified retrospective transition method. See “Note 3. Revenue Recognition” for further information on the adoption of the revenue recognition ASUs.

Cash Flow Classification - In August 2016, the FASB issued an ASU which provides amended guidance on the classification of certain cash receipts and cash payments in the statement of cash flows, including related to debt prepayment or debt extinguishment costs, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance and distributions received from equity method investees. This update is effective for fiscal years beginning after December 15, 2017, including interim periods within those years, and early adoption is permitted. This amended guidance must be applied retrospectively to all periods presented, but may be applied prospectively if retrospective application would be impracticable. The Company adopted this update effective April 1, 2018 using the retrospective method. The new standard did not have a material impact on the Condensed Consolidated Financial Statements.

Goodwill Impairment - In January 2017, the FASB issued an ASU which removes the requirement to compare the implied fair value of goodwill with its carrying amount as part of step 2 of the goodwill impairment test. As a result, under the standards update, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The amendments are effective for annual periods beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company adopted this update effective April 1, 2018. The new standard did not have an impact on the Condensed Consolidated Financial Statements.

Definition of a Business - In January 2017, the FASB issued an ASU to clarify the definition of a business. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill, and consolidation. The amendments are intended to help companies and other organizations evaluate whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments provide a more robust framework to use in determining when a set of assets and activities is a business. The amendments are effective for annual periods beginning after December 15, 2017, including interim periods within those periods. The Company adopted this update effective April 1, 2018. The new standard did not have an impact on the Condensed Consolidated Financial Statements.

Stock-Based Compensation - In May 2017, the FASB issued an ASU to clarify when modification accounting should be applied for changes to the terms or conditions of share-based payment awards. The amendments clarify that modification accounting guidance should only be applied if there is a change to the value, vesting conditions, or award classification and would not be required if the changes are considered non-substantive. The amendments are effective for annual periods beginning after December 15, 2017, including interim periods within those periods. The Company adopted this update effective April 1, 2018. The new standard did not have an impact on the Condensed Consolidated Financial Statements.

Recent Accounting Guidance Not Yet Adopted

Leases - In February 2016, the FASB issued an ASU which amends the guidance for leases. This standard contains principles that will require an entity to recognize most leases on the balance sheet by recording a right-of-use asset and a lease liability, unless the lease is a short-term lease that has an accounting lease term

of twelve months or less. The standard also contains other changes to the current lease guidance that may result in changes to how entities determine which contractual arrangements qualify as a lease, the accounting for executory costs, such as property taxes and insurance, as well as which lease origination costs will be capitalizable. This standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those years. Early adoption of this standard is permitted. The standard allows the use of the modified retrospective transition method, whereby the new guidance will be applied at the beginning of the earliest period presented in the financial statements of the period of adoption. The modified retrospective transition approach includes certain practical expedients that entities may elect to apply in transition. In July 2018, the FASB amended ASC 842 to provide another transition method, allowing a cumulative effect adjustment to the opening balance of retained earnings during the period of adoption. The Company expects to adopt this standard effective April 1, 2019. The Company has implemented a new software solution to improve the process of tracking and accounting for leases under the current and new standards. The Company has not yet determined whether to apply any of the available practical expedients. The Company is in the process of reviewing contracts under the new standard to determine the impact the new standard will have on the Condensed Consolidated Financial Statements.

Measurement of Credit Losses - In June 2016, the FASB issued an ASU which provides amended guidance on the measurement of credit losses on financial instruments, including trade receivables. This standard requires the use of an impairment model referred to as the current expected credit loss model. This standard is effective for fiscal years beginning after December 15, 2019, including interim periods within those years, and early adoption is permitted for fiscal years beginning after December 15, 2018. The Company expects to adopt this standard effective April 1, 2020. The Company is currently evaluating the impact of this standard on the Condensed Consolidated Financial Statements.

Hedge Accounting – In August 2017, the FASB issued an ASU which expands an entity’s ability to apply hedge accounting for non-financial and financial risk components and provides a simplified approach for fair value hedging of interest rate risk. The standard also refines how entities assess hedge effectiveness. This standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those years, and early adoption is permitted. The Company expects to adopt this standard effective April 1, 2019. The Company is currently evaluating the impact of this standard on the Condensed Consolidated Financial Statements.

Fair Value Measurement – In August 2018, the FASB issued an ASU that is intended to improve the effectiveness of disclosures in notes to financial statements. The standard removes, modifies and adds certain disclosure requirements related to fair value measurements. This standard is effective for fiscal years beginning after December 15, 2019. The standard requires the use of the retrospective transition method for specific amendments within the ASU and the prospective treatment of other amendments. Early adoption is permitted. The Company expects to adopt this standard effective April 1, 2020. The Company is currently evaluating the impact of this standard on the Condensed Consolidated Financial Statements.

With the exception of the pronouncements described above, there have been no new accounting pronouncements issued or adopted since the filing of the Fiscal 2018 Form 10-K that have significance, or potential significance, to the Condensed Consolidated Financial Statements.

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

In fiscal 2018, the Company initiated restructuring activities (the “2018 Restructuring Plan”), which will continue throughout fiscal 2019, including closing underutilized manufacturing facilities, reducing headcount, optimizing product offerings and eliminating nonessential costs, designed to improve the Company’s cost structure. The Company closed one and three manufacturing facilities in the six months ended September 30, 2018 and 2017, respectively. As additional restructuring opportunities may be identified, the Company does not have an estimated completion date or expected total cost estimate for the 2018 Restructuring Plan.

Approximately $0.7 million of the Total 2018 Restructuring Plan activities related to the Domestic reporting segment for the three and six months ended September 30, 2018, respectively. Approximately $4.3 million and $7.0 million of the Total 2018 restructuring Plan activities related to the Domestic reporting segment for the three and six months ended September 30, 2017, respectively. There was $0.3 million of the Total 2018 Restructuring Plan activities related to the International reporting segment for the three and six months ended September 30, 2018 and 2017, respectively. There were no 2018 Restructuring Plan activities related to the International reporting segment for the three and six months ended September 30, 2017, respectively.

A reconciliation of the beginning and ending amounts of restructuring liability related to the 2018 Restructuring Plan at September 30, 2018 and 2017 is as follows:

	Six Months Ended September 30,
	2018			2017
(Amounts in thousands)	(In thousands)
Balance at the beginning of the period	$	3,901		$	—

Balance at the end of the period	$	2,307		$	2,824

As of September 30, 2018 and March 31, 2018, the Company had $0.4 million and $0.5 million of long-term severance liability related to the restructuring activities recorded in other liabilities in the Condensed Consolidated Balance Sheet. The current portion of the restructuring liability is recorded in Other accrued liabilities in the Condensed Consolidated Balance Sheet.

3.	REVENUE RECOGNITION

On April 1, 2018, the Company adopted Accounting Standards Codification Topic 606, Revenue from Contracts with Customers (“ASC 606”), and all related amendments using the modified retrospective transition method. The adoption of ASC 606 did not impact the opening retained earnings balance or cause a material shift in the amount or timing of revenue recognition. Results for reporting periods beginning after April 1, 2018 are presented under ASC 606, while prior period amounts were not adjusted and continue to be reported in a consistent manner with historical accounting policies.

Advanced Drainage Systems, Inc.

The Company generates revenue by selling pipe and related water management products primarily to distributors, retailers, buying groups and co-operative buying groups. Products are shipped predominately by the Company’s internal fleet, and the Company does not provide any additional revenue generating services after product delivery. Payment terms and conditions vary by contract.

Revenue is recognized at the point in-time obligations under the terms of a contract with a customer are satisfied, which generally occurs upon the transfer of control of the promised goods. In substantially all of the Company’s contracts with customers, control is transferred to the customer upon delivery. The Company recognizes revenue in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. Revenue is presented in the Condensed Consolidated Statements of Operations net of allowances for returns, rebates, discounts, and taxes collected concurrently with revenue-producing activities.

Refer to “Note 13. Business Segments Information” for the Company’s disaggregation of Net sales by reportable segment. The disclosure of Net sales by reportable segment is aligned by geographical region and product type and best depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors.

Significant Judgments - The Company’s performance obligation under contracts with customers is to sell and deliver pipe and related water management products. The Company’s contracts with customers may contain multiple performance obligations by promising to deliver multiple products to the customer. For these contracts, the Company accounts for individual performance obligations separately if they are distinct. The transaction price is allocated to the separate performance obligations on a relative standalone selling price basis.

The Company’s products are generally sold with a right of return, and the Company may provide credits or incentives, which are accounted for as variable consideration when estimating the amount of revenue to recognize. Variable consideration is estimated at contract inception and updated at the end of each reporting period as additional information becomes available and only to the extent that it is probable that a significant reversal of any incremental revenue will not occur.

Contract Balances - The Company recognizes a contract asset representing the Company’s right to recover products upon the receipt of returned products and a contract liability for the customer refund. The adoption of this standard resulted in the Company recording a contract asset for estimated inventory returns. On April 1, 2018, the estimated inventory returns resulted in a $0.6 million decrease in Receivables, net and a $0.6 million increase in Other current assets on the Company’s Consolidated Balance Sheets. The following table presents the balance of the Company’s contract asset and liability as of September 30, 2018 and April 1, 2018:

	September 30, 2018		April 1, 2018
	(In thousands)
Contract asset - product returns	$	988	$	577
Refund liability		2,249		1,468

Practical Expedients and Exemptions - The Company expenses incremental costs to obtain a contract (e.g. sales commissions) when incurred as the amortization period would have been one year or less. These costs are recorded within selling expenses on the Condensed Consolidated Statements of Operations.

The Company has elected the accounting policy election permitted by ASC 606 to account for shipping and handling costs as activities to fulfill the promise to transfer the goods when these activities are performed after a customer obtains control of the goods. Revenue will be recognized at the point of shipment.

The Company has elected the accounting policy to exclude from the transaction price all sales taxes that are assessed by a governmental authority and that are imposed on and concurrent with a specific revenue-

producing transaction and collected by the Company from a customer, for example, sales, use, value added, and some excise taxes.

Further, the Company does not disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less.

4.	INVENTORIES

Inventories as of the periods presented consisted of the following:

	(In thousands)
Raw materials	$	53,540	$	54,909
Finished goods		193,621		208,883
Total inventories	$	247,161	$	263,792

There were no work-in-process inventories as of the periods presented.

5.	FAIR VALUE MEASUREMENT

When applying fair value principles in the valuation of assets and liabilities, the Company is required to maximize the use of quoted market prices and minimize the use of unobservable inputs. The Company has not changed its valuation techniques used in measuring the fair value of any financial assets or liabilities during the fiscal periods presented. The fair value estimates take into consideration the credit risk of both the Company and its counterparties.

When active market quotes are not available for financial assets and liabilities, ADS uses industry standard valuation models. Where applicable, these models project future cash flows and discount the future amounts to a present value using market-based observable inputs including credit risk, interest rate curves, foreign currency rates and forward and spot prices for currencies. In circumstances where market-based observable inputs are not available, management judgment is used to develop assumptions to estimate fair value. Generally, the fair value of Level 3 instruments is estimated as the net present value of expected future cash flows based on internal and external inputs.

Recurring Fair Value Measurements - The assets and liabilities carried at fair value as of the periods presented were as follows:

	September 30, 2018
	Total		Level 1		Level 2		Level 3
	(In thousands)
Assets:
Derivative assets – diesel fuel contracts	$	698	$	—	$	698	$	—
Interest rate swaps		3,844		—		3,844		—
Total assets at fair value on a recurring basis	$	4,542	$	—	$	4,542	$	—
Liabilities:
Derivative liabilities – diesel fuel contracts	$	360	$	—	$	360	$	—
Contingent consideration for acquisitions		325		—		—		325
Total liabilities at fair value on a recurring basis	$	685	$	—	$	360	$	325

Contingent consideration for acquisitions		578		—		—		578
Total liabilities at fair value on a recurring basis	$	694	$	—	$	116	$	578

For the three and six months ended September 30, 2018 and 2017, respectively, there were no transfers in or out of Levels 1, 2 or 3.

Valuation of Contingent Consideration for Acquisitions - The fair values of the contingent consideration payables for acquisitions were calculated based on a discounted cash flow model, whereby the probability-weighted future payment value is discounted to the present value using a market discount rate. The method used to price these liabilities is considered Level 3, due to the subjective nature of the unobservable inputs used to determine the fair value. Changes in the fair value of recurring fair value measurements using significant unobservable inputs (Level 3) for the periods presented were as follows:

	Three Months Ended September 30,						Six Months Ended September 30,
	2018			2017			2018			2017
	(In thousands)
Balance at the beginning of the period	$	460		$	858		$	578		$	1,348
Change in fair value		7			6			9			32
Payments of contingent consideration liability		(142	)		(129	)		(262	)		(645	)
Balance at the end of the period	$	325		$	735		$	325		$	735

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, or in the case of derivative instruments, because they are recorded at fair value. The carrying and fair value of the Company’s Senior Notes (discussed in “Note 12. Debt” in the Company’s Fiscal 2018 Form 10-K) were $100.0 million and $95.8 million, respectively, as of September 30, 2018 and $125.0 million and $122.3 million, respectively, at March 31, 2018. The fair value of the Senior Notes was determined based on a comparison of the interest rate and terms of such borrowings to the rates and terms of similar debt available for the period. The Company believes the carrying amount on the remaining long-term debt, including the Secured Bank Term Loans, is not materially different from its fair value as the interest rates and terms of the borrowings are similar to currently available borrowings. The categorization of the framework used to evaluate this debt is considered Level 2.

6.	DERIVATIVE TRANSACTIONS

The Company uses interest rate swaps, commodity options in the form of collars and swaps, and foreign currency forward contracts to manage its various exposures to interest rate, commodity price fluctuations and foreign currency exchange rate fluctuations. For the interest rate swap executed on June 28, 2017, gains and losses resulting from the difference between the spot rate and applicable base rate is recorded in Interest expense. For collars, commodity swaps and foreign currency forward contracts, contract settlement gains and losses are recorded in the Condensed Consolidated Statements of Operations in Derivative gains and other income, net.

Gains and losses related to mark-to-market adjustments for changes in fair value of the derivative contracts are also recorded in the Condensed Consolidated Statements of Operations in Derivative gains and other income, net.

The Company recorded net losses and net (gains) on mark-to-market adjustments for changes in the fair value of derivatives contracts as well as net losses and net (gains) on the settlement of derivative contracts as follows:

Stockholders’ Equity –During the six months ended September 30, 2017, the Company repurchased 0.4 million shares of common stock at a cost of $7.9 million. The Company did not repurchase any shares of common stock during the three or six months ended September 30, 2018. The repurchases were made under the Board of Directors’ authorization in February 2017 to repurchase up to $50 million of ADS common stock in accordance with applicable securities laws. As of September 30, 2018, approximately $42.1 million of common stock may be repurchased under the authorization. The repurchase program does not obligate the Company to acquire any particular amount of common stock, and may be suspended or terminated at any time at the Company’s discretion.

In addition, the amendment to the Credit Agreement clarified the process of a transition to replace LIBOR which is being phased out.

10.	COMMITMENTS AND CONTINGENCIES

Purchase Commitments – The Company secures supplies of resin raw material by agreeing to purchase quantities during a future given period at a fixed price. These purchase contracts typically range from 1 to 12 months and occur in the ordinary course of business. Under such non-cancelable purchase contracts in place at September 30, 2018, the Company has agreed to purchase resin over the period October 2018 through December 2018 at a committed purchase cost of $4.4 million.

Litigation and Other Proceedings – As previously disclosed in the Company’s Fiscal 2018 Form 10-K, the Company’s historical accounting practices were the subject of an investigation by SEC’s Division of Enforcement (the “Enforcement Division”), which began in August 2015. That matter was resolved on July 10, 2018 via a settlement between the Company and the SEC. Pursuant to the settlement, the Company consented to the entry of an administrative order without admitting or denying the findings therein. The order required the Company to cease and desist from committing or causing any violations and any future violations of certain provisions of the federal securities laws and the rules promulgated thereunder and to pay a civil monetary penalty of $1.0 million, which payment has been made. The Company previously accrued an expense for the penalty amount during Fiscal 2018.

The Company is involved from time to time in various legal proceedings that arise in the ordinary course of business, including but not limited to commercial disputes, environmental matters, employee related claims, intellectual property disputes and litigation in connection with transactions including acquisitions and divestitures. The Company does not believe that such litigation, claims, and administrative proceedings will

have a material adverse impact on the Company’s financial position or results of operations. The Company records a liability when a loss is considered probable, and the amount can be reasonably estimated.

11.	INCOME TAXES

The Tax Cuts and Jobs Act (the “Tax Act”) was enacted on December 22, 2017. The Tax Act significantly revises the future ongoing U.S. corporate income tax by, among other things, lowering the U.S. corporate income tax rate from 35% to 21%, full expensing on qualified property, eliminates the domestic manufacturing deduction and implements a territorial tax system. The 21% U.S. corporate income tax rate was effective January 1, 2018.

The Company has recognized the provisional tax impacts related to revaluation of deferred tax assets and liabilities and deemed repatriated earnings and included these amounts in its financial statements for the year ended March 31, 2018. The ultimate impact may differ from these provisional amounts, possibly materially, due to, among other things, additional analysis, changes in interpretations and assumptions the Company has made, additional regulatory guidance that may be issued, and actions the Company may take as a result of the Tax Act. During the three months ended September 30, 2018, the Company did not make any adjustments to its provisional amounts included in its Consolidated Financial Statements for the year ended March 31, 2018. The accounting is expected to be finalized in conjunction with the filing of the fiscal 2018 U.S. corporate income tax return, no later than the close of third quarter fiscal 2019.

The Company’s effective tax rate will vary based on a variety of factors, including overall profitability, the geographical mix of income before taxes and related tax rates in jurisdictions where it operates and other onetime charges, as well as discrete events. For the three months ended September 30, 2018 and 2017, the Company utilized an effective tax rate of 28.9% and 42.1%, respectively, to calculate its provision for income taxes. For the six months ended September 30, 2018 and 2017, the Company utilized an effective tax rate of 29.4% and 38.7%, respectively, to calculate its provision for income taxes. These rates are higher than the federal statutory rate primarily due to state and local income taxes and our Employee Stock Ownership Plan (“ESOP”). In addition, the effective tax rate for the six months ended September 30, 2017 differed from the federal statutory rate due to the favorable impact of a $1.0 million discrete income tax benefit related to the release of tax reserves recorded during the three months ended June 30, 2017.

12.	STOCK-BASED COMPENSATION

ADS has several programs for stock-based payments to employees and non-employee members of its Board of Directors, including stock options and restricted stock. Equity-classified restricted stock awards are measured based on the grant-date estimated fair value of each award. The Company accounts for all restricted stock granted to Directors as equity-classified awards. The Company recognized stock-based compensation expense in the following line items of the Condensed Consolidated Statements of Operations for the three and six months ended September 30, 2018 and 2017:

	Three Months Ended September 30,				Six Months Ended September 30,

2017 Omnibus Plan

On May 24, 2017, the Board of Directors approved the 2017 Omnibus Incentive Plan (the “2017 Incentive Plan”) which was approved by the Company’s stockholders on July 17, 2017. The 2017 Incentive Plan provides for the issuance of a maximum of 3.5 million shares of the Company’s common stock for awards made thereunder, which awards may consist of stock options, restricted stock, restricted stock units, stock appreciation rights, phantom stock, cash-based awards, performance awards (which may take the form of performance cash, performance units or performance shares) or other stock-based awards.

During the three months ended September 30, 2018, the Company granted 0.1 million shares of restricted stock to non-employee directors with a grant date fair value of $1.1 million. During the six months ended September 30, 2018, the Company granted 0.1 million shares of restricted stock with a grant date fair value of $3.4 million.

Performance Units - In addition, during the six months ended September 30, 2018, the Company granted 0.1 million performance units, subject to performance and services conditions. The grant date fair value of the performance units was $2.8 million, based on the market price of the Company’s common stock at the date of the grant. For the performance units, 50% of the award is based upon the achievement of certain levels of Return on Invested Capital for the performance period and 50% is based upon the achievement of certain levels of Free Cash Flow for the performance period. The performance units have a 3-year performance period from April 1, 2018 through March 31, 2021. The performance units, and any accrued dividend equivalents, will be settled in shares of the Company’s common stock, if the applicable performance and service conditions are satisfied.

Options – During the three months ended September 30, 2018, the Company did not grant any stock options under the 2017 Incentive Plan. During the six months ended September 30, 2018, the Company granted 0.2 million nonqualified stock options under the 2017 Incentive Plan. The grant date fair value of the nonqualified stock options was $1.9 million. The Company estimates the fair value of stock options using a Black-Scholes option-pricing model. The following table summarizes the assumptions used in estimate the fair value of stock-options during the six months ended September 30, 2018:

		Six Months Ended September 30, 2018
Common stock price		$25.75
Expected stock price volatility		30.5%
Risk-free interest rate		2.9%
Weighted-average expected option life (years)		6.0
Dividend yield		1.2%

13.	BUSINESS SEGMENTS INFORMATION

The Company operates its business in two distinct operating and reportable segments based on the markets it serves: “Domestic” and “International.” The Chief Operating Decision Maker (“CODM”) evaluates segment reporting based on Net sales and Segment Adjusted EBITDA. The Company calculates Segment Adjusted EBITDA as net income or loss before interest, income taxes, depreciation and amortization, stock-based compensation expense, non-cash charges and certain other expenses. Beginning April 1, 2018, the Company revised its allocation of allowances for returns, rebates, and discounts between Pipe and Allied Products for segment reporting purposes. Prior to April 1, 2018, the Company allocated substantially all returns, rebates, and discounts to Pipe net sales. These changes did not impact the Company’s previously reported consolidated financial results. The prior period segment results and related disclosures have been recast to conform to the current year presentation under the new allocation methodology. 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:

Management’s Discussion and Analysis of Financial Condition and Results of Operations

Unless the context otherwise indicates or requires, as used in this Quarterly Report on Form 10-Q, the terms “we,” “our,” “us,” “ADS” and the “Company” refer to Advanced Drainage Systems, Inc. and its directly- and indirectly-owned subsidiaries as a combined entity, except where it is clear that the terms mean only Advanced Drainage Systems, Inc. exclusive of its subsidiaries.

Our fiscal year begins on April 1 and ends on March 31. Unless otherwise noted, references to “year” pertain to our fiscal year. For example, 2019 refers to fiscal 2019, which is the period from April 1, 2018 to March 31, 2019.

The following discussion and analysis of the financial condition and results of our operations should be read in conjunction with our Condensed Consolidated Financial Statements and related footnotes included elsewhere in this Quarterly Report on Form 10-Q and with the audited Consolidated Financial Statements included in our Fiscal 2018 Form 10-K, as filed with the Securities and Exchange Commission (the “SEC”) on May 30, 2018. In addition to historical condensed consolidated financial information, the following discussion contains forward-looking statements that reflect our plans, estimates and beliefs. Our actual results could differ materially from those discussed in the forward-looking statements. This discussion contains forward-looking statements that are based on the beliefs of our management, as well as assumptions made by, and information currently available to, our management. Our actual results could differ materially from those discussed in the forward-looking statements. For more information, see the section below entitled “Forward Looking Statements.”

We consolidate all of our joint ventures for purposes of GAAP, except for our South American Joint Venture and our former joint venture, Tigre-ADS USA.

Overview

We are the leading manufacturer of high performance thermoplastic corrugated pipe, providing a comprehensive suite of water management products and superior drainage solutions for use in the underground construction and infrastructure marketplace. Our innovative products are used across a broad range of end markets and applications, including non-residential, residential, agriculture and infrastructure applications. We have established a leading position in many of these end markets by leveraging our national sales and distribution platform, our overall product breadth and scale and our manufacturing excellence. In the United States, our national footprint combined with our strong local presence and broad product offering make us the leader in an otherwise highly fragmented sector comprised of many smaller competitors. We believe the markets we serve in the United States represent approximately $11 billion of annual revenue opportunity. In addition, we believe the increasing acceptance of thermoplastic pipe products in international markets represents an attractive growth opportunity.

Our products are generally lighter, more durable, more cost effective and easier to install than comparable alternatives made with traditional materials. Following our entrance into the non-residential construction market with the introduction of N-12 corrugated polyethylene pipe in the late 1980s, our pipe products have been displacing products made with traditional materials, such as reinforced concrete, corrugated steel and polyvinyl chloride (“PVC”), across an ever expanding range of end markets. This has allowed us to consistently gain market share and achieve above-market growth throughout economic cycles. We expect to continue to drive conversion to our products from traditional materials as contractors, civil design engineers and municipal agencies increasingly acknowledge the superior physical attributes and compelling value proposition of our thermoplastic products. In addition, we believe that overall demand for our products will benefit as the regulatory environment continues to evolve.

Our broad product line includes HDPE pipe, PP pipe and related water management products. Building on our core drainage businesses, we have aggressively pursued attractive ancillary product categories such as storm and septic chambers, PVC drainage structures, fittings and filters, and water quality filters and separators. We refer to these ancillary product categories as Allied Products. Given the scope of our overall sales and distribution platform, we have been able to drive growth within our Allied Products and believe there are significant growth opportunities going forward.

Restructuring Activities

In fiscal 2018, we initiated restructuring activities designed to improve our cost structure, including closing underutilized manufacturing facilities, reducing headcount and eliminating nonessential costs. These activities will continue throughout fiscal 2019. The Company closed one and three manufacturing facilities in the six months ended September 30, 2018 and 2017, respectively. The following table summarizes the restructuring activity included in Loss on disposal of assets and costs from exit and disposal activities recorded during the three and six months ended September 30, 2018 and 2017:

Total gross profit	$	95,373	$	89,801	$	5,572		6.2	%

The increase in domestic gross profit of $1.1 million, or 1.3%, was primarily due to decreased labor and overhead costs of $1.8 million. This increase was offset by the gross profit impact of the decreased sales discussed above and increased material and transportation costs.

International gross profit increased $4.5 million, or 73.8%, in the three months ended September 30, 2018 compared to the same period in the previous fiscal year, primarily due to the gross profit impact of the net sales increase discussed above. In addition, we implemented cost containment measures to mitigate increasing material costs.

Selling expenses - As a percentage of net sales, selling expenses were relatively flat at 6.1% in the three months ended September 30, 2018 and 2017.

General and administrative expenses - General and administrative expenses for the three months ended September 30, 2018 decreased $2.3 million from the prior year period. The decrease was primarily due to a decrease in professional and legal fees $0.5 million.

Loss on disposal of assets and costs from exit and disposal activities – In the three months ended September 30, 2018, we recorded $1.0 million of expense related to restructuring activities, including closing one underutilized manufacturing facility. In addition, we recorded a gain on other disposals and partial disposals of property, plant and equipment of approximately $0.7 million. See “Note 2. Loss on Disposal of Assets and Costs from Exit and Disposal Activities” for additional discussion.

Intangible amortization - Intangible amortization remained relatively flat as a percentage of net sales.

Interest expense - Interest expense decreased $0.5 million in the three months ended September 30, 2018 compared to the same period in the previous fiscal year, primarily due to a $0.4 million unrealized gain on the interest rate swap.

Derivative losses (gains) and other expense (income), net - Derivative gains and other income decreased by $2.6 million for the three months ended September 30, 2018 compared to the same period in the previous fiscal year. The decrease is primarily due to changes in realized foreign currency gains and losses.

Income tax expense - For the three months ended September 30, 2018 and 2017, the effective tax rates were 28.9% and 42.1%, respectively. The decrease in the effective tax rate was primarily due to impact of the Tax Cuts and Jobs Act (the “Tax Act”).

Non-GAAP Financial Measures

In addition to financial results reported in accordance with GAAP, we have provided the following non-GAAP financial measures: Adjusted EBITDA and Free Cash Flow. These non-GAAP financial measures are used in addition to and in conjunction with results presented in accordance with GAAP. However, these measures are not intended to be a substitute for those reported in accordance with GAAP. These measures may be different from non-GAAP financial measures used by other companies, even when similar terms are used to identify such measures.

Adjusted EBITDA - Adjusted EBITDA, a non-GAAP financial measure, has been presented in this Quarterly Report on Form 10-Q as a supplemental measure of financial performance that is not required by, or presented 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.

Adjusted EBITDA is included in this Quarterly Report on Form 10-Q because it is a key metric used by management and our Board of Directors to assess our financial performance. Adjusted EBITDA is 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 adjusted EBITDA to supplement GAAP measures of performance to evaluate the effectiveness of our business strategies, to make budgeting decisions and to compare our performance against that of other peer companies using similar measures.

Adjusted EBITDA is not a GAAP measure of our financial performance and should not be considered as an alternative to net income as a measure of financial performance or cash flows from operations or any other performance measure derived in accordance with GAAP, and it should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items. Adjusted EBITDA contains certain other limitations, including the failure to reflect our cash expenditures, cash requirements for working capital needs and cash costs to replace assets being depreciated and amortized. In evaluating adjusted EBITDA, 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. Our presentation of adjusted EBITDA should not be construed to imply that our future results will be unaffected by any such adjustments. Management compensates for these limitations by relying on our GAAP results in addition to using adjusted EBITDA as a supplemental measurement. Our measure of adjusted EBITDA is not necessarily comparable to other similarly titled captions of other companies due to different methods of calculation.

Free Cash Flow - Free cash flow is a non-GAAP financial measure that comprises cash flow from operations less capital expenditures. Free cash flow is a measure used by management and our Board of Directors to assess our ability to generate cash. Accordingly, free cash flow has been presented in this Quarterly Report on Form 10-Q 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 flow from operating activities, the most comparable GAAP measure, for each of the periods indicated.

Liquidity and Capital Resources

Our primary liquidity requirements are working capital, capital expenditures, debt service, and dividend payments for our convertible preferred stock and common stock. We have historically funded, and expect to continue to fund, our operations primarily through internally generated cash flow, debt financings, equity issuance and capital and operating leases. 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.

As of September 30, 2018, we had $12.0 million in cash that was held by our foreign subsidiaries. Prior to the Tax Act, our intent was to indefinitely reinvest our earnings in foreign subsidiaries with the exception of cash dividends paid by our ADS Mexicana joint venture. As a result of the Tax Act, we continue to evaluate our strategy with our foreign cash, but we still intend to indefinitely reinvest our earnings in foreign subsidiaries.

Working Capital and Cash Flows

As of September 30, 2018, we had $455.9 million in liquidity, including $17.6 million of cash, $363.3 million in borrowings available under our Revolving Credit Facility net of $8.5 million of outstanding letters of credit, and $75.0 million under the Senior Notes, described below. We believe that our cash on hand, together with the availability of borrowings under our Revolving Credit Facility and other financing arrangements and cash generated from operations, will be sufficient to meet our working capital requirements, anticipated capital expenditures, scheduled principal and interest payments on our indebtedness and the dividend payment requirement for our convertible preferred stock for at least the next twelve months.

Working Capital - Working capital increased to $288.2 million as of September 30, 2018, from $237.2 million as of March 31, 2018. The increased in working capital is primarily due to an increase in accounts receivables of $65.0 million due to the seasonality of operations offset by a $16.6 million decrease in inventory.

Operating Cash Flows - Cash flows provided by operating activities for the six months ended September 30, 2018 was $58.2 million as compared with cash provided by operating activities of $28.4 million for the six months ended September 30, 2017. Cash flows from operating activities during the six months ended September 30, 2018 was primarily impacted by increased income from continuing operations and changes in working capital.

Investing Cash Flows - During the six months ended September 30, 2018 and 2017, cash used for investing activities was $18.9 million and $29.4 million, respectively. The decrease in cash used for investing activities was primarily due to decreases in capital expenditures and purchases of property, plant and equipment through financing. Our capital expenditures for the six months ended September 30, 2018 were used primarily for new equipment and facility expansions and upgrades.

Financing Cash Flows - During the six months ended September 30, 2018, cash used for financing activities was $39.1 million due to payments on our Senior Notes, payments on our capital lease obligations and dividends paid offset by net borrowings on our Revolving Credit Facility. During the six months ended September 30, 2017, cash provided by financing activities was $6.2 million, due to increased borrowings on our Senior Notes and Revolving Credit Facility associated with the debt refinancing, partially offset by increased repayments on our Revolving Credit facility and Term Loan, and $7.9 million of repurchases of our common stock under the stock repurchase program.

Capital Expenditures

Capital expenditures totaled $19.3 million and $27.0 million for the six months ended September 30, 2018 and 2017, respectively. Our capital expenditures for the six months ended September 30, 2018 were used primarily to support facility expansions, equipment replacements, our recycled resin initiatives and technology.

We currently anticipate that we will make capital expenditures of approximately $50 to $60 million in fiscal year 2019. Such capital expenditures are expected to be financed using funds generated by operations. As of September 30, 2018, there were no material contractual obligations or commitments related to these planned capital expenditures.

Employee Stock Ownership Plan (“ESOP”)

The Company established the Advanced Drainage Systems, Inc. ESOP (the “ESOP” or the “Plan”) effective April 1, 1993 to enable eligible employees to acquire stock ownership in ADS in the form of redeemable convertible preferred shares. The Plan was funded by an existing tax-qualified profit-sharing retirement plan, as well as a 30-year term loan from ADS. Within 30 days following the repayment of the ESOP loan, which will occur no later than March 2023, the shares of redeemable convertible preferred stock owned by the ESOP will be converted into shares of the Company’s common stock.

The Company is obligated to make contributions to the Plan, which, when aggregated with the Plan’s dividends, equal the amount necessary to enable the Plan to make its regularly scheduled payments of principal and interest due on its term loan to ADS. Compensation expense is recognized based upon the average annual fair value of the shares during the period which ADS receives payments on the term loan, and the number of ESOP shares allocated to participant accounts.

As disclosed in “Note 15. Employee Benefit Plans” to the Consolidated Financial Statements included in “Item 8. Financial Statements and Supplementary Data” of our Fiscal 2018 Form 10-K, redeemable convertible preferred stock can convert to common stock upon retirement, disability, death, or vested terminations over the life of the Plan. As stated above, within 30 days following the repayment of the ESOP loan, all redeemable convertible preferred stock will be converted to common stock, which will be no later than March 2023.

The ESOP’s conversion of redeemable convertible preferred stock into common stock will have a meaningful impact on the Company’s net income, net income per share and common shares outstanding. The outstanding shares of common stock would be 31% greater after conversion.

Impact on Net Income – Following the repayment of the ESOP loan discussed above, the Company will no longer be required to apply the two-class method to determine Net income per share. In addition, the Company would not be required to recognize the fair value of ESOP deferred compensation attributable to the shares of redeemable convertible preferred shares allocated.

The impact of the ESOP on net income includes the fair value of ESOP deferred compensation attributable to the shares of redeemable convertible preferred stock allocated to employee ESOP accounts during the applicable period, which is a non-cash charge to our earnings and not deductible for income tax purposes.

Financing Transactions

Secured Bank Term Loans - On June 22, 2017, we entered into a Second Amended and Restated Credit Agreement with PNC, which amends and restates the original agreement dated as of June 12, 2013, to provide us a $550 million Revolving Credit Facility, which is more fully described in our Fiscal 2018 Form 10-K.

As of September 30, 2018, the outstanding principal drawn on the Revolving Credit Facility was $178.2 million, with $363.3 million available to be drawn on the U.S. facility, net of $8.5 million of outstanding letters of credit.

ADS Mexicana Revolving Credit Facility - On June 22, 2018, the Company’s $12.0 million Revolving Credit Facility – ADS Mexicana matured. At June 22, 2018, there were no borrowings under the Revolving Credit Facility – ADS Mexicana.

ADS Mexicana’s Revolving Credit Facility was replaced by an Intercompany Revolving Credit Promissory Note (the “Intercompany Note”) with a capacity of $12.0 million. The Intercompany Note matures on June 22, 2022. The Intercompany Note indemnifies the ADS Mexicana joint venture partner for 49% of any unpaid borrowing. The interest rates under the Intercompany Note are determined by certain base rates or LIBOR rates plus an applicable margin based on the Leverage Ratio. As of September 30, 2018 there were no borrowings under the Intercompany Note.

Fiscal 2019 Amendment to the Secured Bank Term Loans – On July 9, 2018, the Company amended the Second Amended and Restated Credit (the “Credit Agreement”) and the Second Amended and Restated Private Shelf Agreement (the “Private Shelf Agreement”) to amend the definition of Consolidated EBITDA and changed the timing of the quarterly rate adjustments. In addition, the amendment to the Credit Agreement clarified the process of a transition to replace LIBOR which is being phased out.

Senior Notes - On December 11, 2009, we entered into a private shelf agreement with Prudential Investment Management Inc., or Prudential, which agreement, as amended and restated on September 24, 2010 and subsequently further amended, provides for the issuance by us of senior secured promissory notes to Prudential or its affiliates from time to time in the aggregate principal amount up to $100 million. On June 22, 2017, we entered into the Second Amended and Restated Private Shelf Agreement with Prudential, which amends and restates the agreement dated as of September 24, 2010, to provide for the issuance of secured senior notes to Prudential or its affiliates from time to time in the aggregate principal amount of up to $175 million, which is more fully described in

our Fiscal 2018 Form 10-K. We have $75 million available for issuance of senior notes under the private shelf agreement. At September 30, 2018, the outstanding principal balance on these notes was $100 million.

Covenant Compliance

Our outstanding debt agreements and instruments contain various restrictive covenants including, but not limited to, limitations on additional indebtedness and capital distributions, including dividend payments. The two primary debt covenants of the amended ADS Revolving Credit Facility and Senior Notes include a Leverage Ratio and an Interest Coverage Ratio maintenance covenant. For any relevant period of determination, the Leverage Ratio is calculated by dividing Total Consolidated Indebtedness (funded debt plus guarantees) by Consolidated EBITDA, as defined by the credit facility. The current upper limit is 4.0 times (or 4.25 as of the date of any acquisitions permitted under the amended agreement for which the aggregate consideration is $100.0 million or greater). The Interest Coverage Ratio is calculated by dividing the sum of Consolidated EBITDA by consolidated interest expense. The current minimum ratio is 3.0 times.

For further information, see “Note 12. Debt” to the Consolidated Financial Statements included in “Item 8. Financial Statements and Supplementary Data” of our Fiscal 2018 Form 10-K. We were in compliance with our debt covenants as of September 30, 2018.

Off-Balance Sheet Arrangements

Excluding the guarantees of 50% of certain debt of our unconsolidated South American Joint Venture as further discussed in “Note 8. Related Party Transactions” to the Condensed Consolidated Financial Statements, we do not have any other off-balance sheet arrangements. As of September 30, 2018, our South American Joint Venture had approximately $13.2 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

With the exception of the accounting pronouncements adopted during fiscal 2018 discussed in “Note 1. Background and Summary of Significant Accounting Policies” and “Note 3. Revenue Recognition,” 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 2018 Form 10-K.

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 Annual Report on Form 10-K for the fiscal year ended March 31, 2018.

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 Securities Exchange Act of 1934, as amended (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 those material weaknesses, and the evaluation of our disclosure controls and

PART II. OTHER INFORMATION

Item 1.

Legal Proceedings

As previously disclosed in the Company’s Fiscal 2018 Form 10-K, the Company’s historical accounting practices were the subject of an investigation by SEC’s Division of Enforcement (the “Enforcement Division”), which began in August 2015. That matter was resolved on July 10, 2018 via a settlement between the Company and the SEC. Pursuant to the settlement, the Company consented to the entry of an administrative order without admitting or denying the findings therein. The order required the Company to cease and desist from committing or causing any violations and any future violations of certain provisions of the federal securities laws and the rules promulgated thereunder and to pay a civil monetary penalty of $1.0 million, which payment has been made. The Company previously accrued an expense for the penalty amount during Fiscal 2018.

Please see “Note 10. Commitments and Contingencies,” of the Condensed Consolidated Financial Statements of this Quarterly Report on Form 10-Q for more information regarding legal proceedings.
