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. With the acquisition of
Infiltrator Water Technologies in the second quarter of fiscal 2020, we are now
a leading provider of plastic leach field chambers, septic tanks and accessories
for use primarily in residential applications.

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
has been displacing traditional materials, such as reinforced concrete,
corrugated steel and PVC, across an ever-expanding range of end markets. This
has allowed us to consistently gain 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, related water management
products and, after the Acquisition, plastic leach field chambers and septic
tanks. We refer to our plastic leach field chamber and septic tank products as
Infiltrator Water Technologies. Infiltrator Water Technologies shares a similar
conversion strategy as our Pipe products, gaining market share through
conversion from traditional materials. Building on our core drainage businesses,
we have aggressively pursued attractive ancillary product categories such as
storm chambers, PVC drainage structures, fittings and filters, and water quality
filters and separators, including our acquisition of Infiltrator Water
Technologies. We refer to our ancillary product categories as Allied Products &
Other. Given the scope of our overall sales and distribution platform, we have
been able to drive growth within our Allied Products & Other and believe there
are significant growth opportunities going forward.

Executive Summary

Fiscal Year 2020 Results

• Net sales increased 20.9% to $1,673.8 million

• Net loss of $191.8 million as compared to net income of $81.5 million in


          the prior year


                o   Includes $246.8 million of additional one-time ESOP
                    stock-based compensation expense


  • Adjusted EBITDA increased 56.0% to $361.9 million

• Cash provided by operating activities increased 101.9% to $306.2 million

• Free cash flow increased 120.3% to $238.5 million




Net sales increased $289.1 million, or 20.9%, to $1,673.8 million, as compared
to $1,384.7 million in the prior year. Domestic pipe sales increased $85.8
million, or 9.9%, to $954.6 million. Allied & Other sales increased $47.9
million, or 13.5%, to $403.3 million. These increases were driven by strong
performance in both the U.S. construction and agriculture end markets.
International net sales decreased $12.0 million or 7.5% to $148.6 million as
compared to $160.6 million in the prior year, driven primarily by a decrease in
Mexico sales. Infiltrator Water Technologies contributed an additional $211.0
million to net sales prior to the effects of intercompany eliminations.



As part of the Company's capital allocation strategy, the Company paid a
dividend of $1.09 per share in the first quarter of fiscal 2020, including a
$1.00 special dividend to all shareholders of record. The ESOP used a portion of
its proceeds to payback a portion of its loan from the Company, resulting in an
allocation of approximately 11.6 million shares to participants and $246.8
million of non-cash, stock-based compensation expense. The Company recorded
$168.6 million of this expense in Cost of goods sold - ESOP special dividend
compensation and $78.1 million of this expense in Selling, general and
administrative - ESOP special dividend compensation.

Gross profit decreased $10.5 million to $316.5 million due to the $168.6 million
ESOP compensation expense described above. Excluding the ESOP special dividend
compensation, gross profit increased $158.1 million, or 48.4%, primarily due to
an increase in both pipe and allied product sales as well as favorable pricing
and material cost. Infiltrator Water Technologies contributed an additional
$82.9 million of gross profit prior to the effects of intercompany eliminations.
This was partially offset by unfavorable inventory absorption cost due to the
retention of key manufacturing employees during the fourth quarter of fiscal
2019 despite lower production volume.

Impact of COVID-19



In March 2020, the World Health Organization categorized the novel coronavirus
("COVID-19") as a pandemic, and it continues to spread throughout the United
States and globally. The COVID-19 pandemic has resulted, and is likely to
continue to result, in significant economic disruptions and may have an adverse
effect on our business. Significant uncertainty exists concerning the magnitude
of the impact and duration of the COVID-19 pandemic. While our production
facilities are operating as essential businesses, the Company may experience
future impacts such as reduced operations or temporarily closing facilities.

                                       45

In efforts to maintain a safe work environment and help contain the spread of
COVID-19, we have transitioned to a work-from-home policy for those that are
able and suspended all nonessential employee travel and events. We have also
proactively implemented further safety and risk mitigation practices, including:

• Educating associates on COVID-19 related symptoms;




     •    Regularly assessing deliveries and orders in virus "hot zones" and
          higher-risk geographic regions;

• Employing strict social distancing practices across all departments and

divisions; and

• Instituting additional health screenings such as temperature checks at

facilities, which currently all remain open.




Importantly, we are following all guidelines and directives from governmental
and regulatory agencies across manufacturing facilities, distribution centers,
and delivery fleets in order to continue operating safely and responsibly, while
meeting the needs of customers.

Factors deriving from the COVID-19 response that have or may negatively impact
sales and operating profit in the future include, but are not limited to:
limitations on our ability to procure raw materials, declines in product demand,
limitations on our ability to meet delivery requirements and commitments,
limitations on the ability of our employees to perform their work due to illness
caused by the pandemic or local, state, or federal orders requiring employees to
remain at home and limitations on the ability of our customers to pay us on a
timely basis.

While we may experience unfavorable impacts to our business, given the dynamic
nature of these circumstances, the full extent of the COVID-19 pandemic on our
ongoing business, results of operations and overall financial performance is
difficult to forecast at this time. In fiscal 2020, we communicated to all
hourly employees that each of them would be entitled to the equivalent of two
weeks, or 80 hours, of pandemic pay regardless of whether they experienced any
interruption of employment. We recognized pandemic pay costs and accrued
pandemic pay liability of $4.8 million in the fiscal year ended March 31, 2020.
The cash payment of pandemic pay did not occur in fiscal 2020 and will occur at
a future date. Also, we have deferred payment of the Company's share of Social
Security payroll taxes as permitted under the Coronavirus Aid, Relief, and
Economic Security Act (the "CARES Act"), which allows for the deferral of these
payments through the end of 2020 and requires repayment of the deferred amounts
in 2021 and 2022.

Key Factors Affecting Our Results of Operations



Product Demand - There are numerous factors that influence demand for our
products. Our businesses are cyclical in nature and sensitive to general
economic conditions, primarily in the United States, Canada, Mexico and South
America. The non-residential, residential, agricultural and infrastructure
markets we serve are affected by the availability of credit, lending practices,
interest rates and unemployment rates. Demand for new homes, farm income,
commercial development and highway infrastructure spending have a direct impact
on our financial condition and results of operations. Accordingly, the following
factors may have a direct impact on our business in the markets in which our
products are sold:

  • the strength of the economy;


  • the amount and type of non-residential and residential construction;


  • funding for infrastructure spending;


  • farm income and agricultural land values;


  • inventory of improved housing lots;


  • changes in raw material prices;


  • the availability and cost of credit;


  • non-residential occupancy rates;


                                       46

  • commodity prices; and

• demographic factors such as population growth and household formation.




Product Pricing - The price of our products is impacted by competitive pricing
dynamics in our industry as well as by raw material input costs. Our industry is
highly competitive and the sales prices for our products may vary based on the
sales policies of our competitors. Raw material costs represent a significant
portion of the cost of goods sold for our products. We aim to increase our
product selling prices in order to cover raw material price increases, but the
inability to do so could impact our profitability. Movements in raw material,
logistics or other overhead costs and resulting changes in the selling prices
may also impact changes in period-to-period comparisons of net sales.

Material Conversion - Our HDPE and PP pipe, plastic leach field chambers, septic
tanks and related water management product lines compete with other
manufacturers of corrugated polyethylene pipe as well as manufacturers of
alternative products made with traditional materials, such as concrete, steel
and PVC. Our net sales are driven by market trends, including the continued
increase in adoption of thermoplastic corrugated pipe products as a replacement
for traditional materials. Thermoplastic corrugated pipe is generally lighter,
more durable, more cost effective and easier to install than comparable products
made from traditional materials. We believe customers will continue to
acknowledge the superior attributes and compelling value proposition of our
thermoplastic products and expanded regulatory approvals allow for their use in
new markets and geographies. In addition, we believe that PP pipe products will
also help accelerate conversion given the additional applications for which our
PP pipe products can be used.

We believe the adoption of HDPE and PP pipe outside of the United States is
still in its early stages and represents a significant opportunity for us to
continue to increase the conversion to our products from traditional products in
these markets, including Canada, Mexico and South America where we operate.

Growth in Allied Products & Other - Our Allied Products & Other include storm
and septic chambers, PVC drainage structures, fittings, stormwater filters and
water separators. These products complement our pipe product lines and allow us
to offer a comprehensive water management solution to our customers and drive
organic growth. Our leading market position in pipe products allows us to
cross-sell Allied Products & Other effectively. Our comprehensive offering of
Allied Products & Other also helps us increase pipe sales in certain markets.
Our Allied Products & Other are less sensitive to increases in resin prices
since resin prices represent a smaller percentage of the cost for Allied
Products & Other.

Our leading position in the pipe market has allowed us to increase organic growth of our Allied Products & Other. We also expect to expand our Allied Product offerings through acquisitions.



Raw Material Costs - Our raw material cost and product selling prices fluctuate
with changes in the price of resins utilized in production. We actively manage
our resin purchases and pass fluctuations in the cost of resin through to our
customers, where possible, in order to maintain our profitability. Fluctuations
in the price of crude oil and natural gas prices may impact the cost of resin.
In addition, changes in and disruptions to existing ethylene or polyethylene
capacities could also significantly increase resin prices, often within a short
period of time, even if crude oil and natural gas prices remain low. Our ability
to pass through raw material price increases to our customers may, in some
cases, lag the increase in our costs of goods sold. Sharp rises in raw material
prices over a short period of time have historically occurred with a significant
supply disruption (hurricanes or fires at petrochemical facilities), which may
increase prices to levels that cannot be fully passed through to customers due
to pricing of competing products made from different raw materials or the
anticipated length of time the raw material pricing will stay elevated. For more
information regarding risks relating to our raw material costs, see "Item 1A.
Risk Factors - Risks Relating to Our Business."

We currently purchase in excess of 1,100 million pounds of virgin and recycled
resin annually from over 470 suppliers in North America. As a high-volume buyer
of resin, we are able to achieve economies of scale to negotiate favorable terms
and pricing. Our purchasing strategies differ based on the material (virgin
resin versus recycled material) ordered for delivery to our production
locations. The price movements of the different materials also vary, resulting
in the need to use a number of strategies to reduce volatility.

                                       47

--------------------------------------------------------------------------------

Table of Contents

Advanced Drainage Systems, Inc.

In order to reduce the volatility of raw material costs in the future, our raw material strategies for managing our costs include the following:



     •    increasing the use of less price-volatile recycled HDPE resin in our
          pipe products in place of virgin resin while meeting or exceeding
          industry standards;

• internally processing an increasing percentage of our recycled HDPE

resin in order to closely monitor quality and minimize costs

(approximately 81% of our recycled HDPE resin was internally processed

(enhanced) in fiscal 2020);

• managing a resin price risk program that may entail both physical fixed

price and volume contracts along with financial hedges. For our PP

virgin resin price exposure, we have the ability to utilize financial

hedges of propylene as a proxy for PP; and

• maintaining supply agreements with our major resin suppliers that

provide multi-year terms and volumes that are in excess of our projected

consumption.




We also consume a large amount of energy and other petroleum products in our
operations, including the electricity we use in our manufacturing process as
well as the diesel fuel consumed in delivering a significant volume of products
to our customers through our in-house fleet. As a result, our operating profit
also depends upon our ability to manage the cost of the energy and fuel we
require, as well as our ability to pass through increased prices or surcharges
to our customers.

Seasonality - Our operating results are impacted by seasonality. Historically,
sales of our products have been higher in the first and second quarters of each
fiscal year due to favorable weather and longer daylight conditions accelerating
construction project activity during these periods while fourth quarter results
are impacted by the timing of spring in the northern United States and Canada.
Seasonal variations in operating results may also be significantly impacted by
inclement weather conditions, such as cold or wet weather, which can delay
projects, resulting in decreased net sales for one or more quarters, but we
believe that these delayed projects generally result in increased net sales
during subsequent quarters.

In the non-residential, residential and infrastructure markets in the northern
United States and Canada, the construction season typically begins to gain
momentum in late March and lasts through November, before winter sets in,
significantly slowing the construction markets. In the southern and western
United States, Mexico, Central America and South America, the construction
markets are less seasonal. The agricultural drainage market is concentrated in
the early spring just prior to planting and in the fall just after crops are
harvested prior to freezing of the ground in winter.

Currency Exchange Rates - Although we sell and manufacture our products in many
countries, our sales and production costs are primarily denominated in U.S.
dollars. We have wholly-owned facilities in Canada, the Netherlands and joint
venture facilities in Mexico, Chile, Brazil, Argentina, Colombia and Peru. The
functional currencies in the areas in which we have wholly-owned facilities and
joint venture facilities other than the U.S. dollar are the Canadian dollar,
Euro, Mexican peso, Chilean peso, Brazilian real and Colombian peso. In fiscal
2019, we converted the functional currency of joint venture facilities using the
Argentine peso to the Chilean peso. From time to time, we use derivatives to
reduce our exposure to currency fluctuations.

Description of our Segments



Following the acquisition of Infiltrator Water Technologies, we revised our
reportable segments to reflect how the Chief Operating Decision Maker ("CODM")
currently reviews financial information and makes operational decisions. After
the Acquisition, we operate our business in three distinct reportable segments:
"Pipe", "International" and "Infiltrator Water Technologies." "Allied Products &
Other" represents our Allied Products and all other business segments. "Pipe"
and "Allied Products & Other" were previously disclosed as our Domestic segment.

We generate a greater proportion of our net sales and gross profit in our Pipe segment, which consists of Pipe product sales in all regions of the United States. We expect the percentage of total net sales and gross profit derived


                                       48

from our other segments to continue to increase in future periods as we continue
to expand non-Pipe product and our international presence. See "Note 21.
Business Segment Information," to our audited consolidated financial statements
included in "Item 8. Financial Statements and Supplementary Data" of this Form
10-K.

Pipe - Our Pipe segment manufactures and markets high performance thermoplastic
corrugated pipe throughout the United States. We maintain and serve these
markets through product distribution relationships with many of the largest
national and independent waterworks distributors, buying groups and co-ops,
major national retailers as well as an extensive network of hundreds of small to
medium-sized distributors across the United States. For fiscal 2020, 2019 and
2018, we generated net sales attributable to our Pipe segment of $954.6 million,
$868.8 million, and $844.9 million, respectively.

Infiltrator Water Technologies -Infiltrator Water Technologies is a leading
national provider of plastic leach field chambers and systems, septic tanks and
accessories, primarily for use in residential applications. Infiltrator Water
Technologies products are used in on-site septic wastewater treatment systems in
the United States and Canada. We acquired Infiltrator Water Technologies on July
31, 2019. We generated net sales to external customers attributable to our
Infiltrator Water Technologies segment of $211.0 million subsequent to the
acquisition.

International - Our International segment manufactures and markets products in
regions outside of the United States, with a strategy focused on our owned
facilities in Canada and those markets serviced through our joint ventures in
Mexico and South America. Pipe manufactured in these countries is primarily sold
into the same region. Our joint venture strategy has provided us with local and
regional access to new markets. For fiscal 2020, 2019, and 2018, we generated
net sales attributable to our International segment of $148.6 million,
$160.6 million, and $155.9 million, respectively. Our investment in the South
American Joint Venture is accounted for under the equity method and is not
consolidated for financial reporting purposes. The unconsolidated sales of the
South American Joint Venture were $52.5 million, $47.6 million, and
$44.6 million, in fiscal 2020, 2019, and 2018, respectively.

Allied Products & Other - Our other operating segments manufacture a range of
Allied Products & Other that are complementary to our Pipe products. Our Allied
Products & Other offer adjacent technologies to our core Pipe offering,
presenting a complete drainage solution for our clients and customers. For
fiscal 2020, 2019 and 2018, our other reporting units generated net sales of
$403.3 million, $355.3 million and $329.6 million, respectively. Unconsolidated
sales for our domestic unconsolidated joint venture, Tigre-ADS USA, prior to the
Company's divestiture in April 2018 were $17.6 million in fiscal 2018.

Non-GAAP Financial Measures



EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin - EBITDA, Adjusted EBITDA and
Adjusted EBITDA Margin, non-GAAP financial measures, have been presented in this
Annual Report on Form 10-K as supplemental measures of financial performance
that are not required by, or presented in accordance with GAAP. We calculate
EBITDA as net income before interest, income taxes and depreciation and
amortization. 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.

EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin are included in this Annual
Report on Form 10-K because they are key metrics used by management and our
Board of Directors to assess our financial performance. EBITDA, Adjusted EBITDA
and Adjusted EBITDA Margin 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 EBITDA,
Adjusted EBITDA and Adjusted EBITDA Margin 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.

EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin are not GAAP measures of our
financial performance 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, and it should not be
construed as an inference that our future results will be unaffected by unusual
or non-recurring items. EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin
contain certain other limitations, including the failure to reflect

                                       49

our cash expenditures, cash requirements for working capital needs and cash
costs to replace assets being depreciated and amortized. In evaluating EBITDA,
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 in
addition to using EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin on a
supplemental basis. Our measure of EBITDA, Adjusted EBITDA and Adjusted EBITDA
Margin are not necessarily comparable to other similarly titled captions of
other companies due to different methods of calculation.

For a reconciliation of EBITDA, Adjusted EBITDA and Adjusted EBITDA Margin to net income (loss), the most comparable GAAP measure, see "Item 6. Selected Financial and Operating Data."

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 Annual Report on
Form 10-K 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.

For a reconciliation of Free cash flow to Cash flow from operating activities,
the most comparable GAAP measure, see "Item 6. Selected Financial and Operating
Data."

        •   Pipe net sales to all customers for fiscal 2020 increased by $85.8
            million, or 9.9% compared to fiscal 2019. The increase was due to an
            increase in pipe volume resulting in a $91.1 million offset by a $7.7
            million decrease as a result of price and product mix.

Advanced Drainage Systems, Inc.

Infiltrator Water Technologies net sales to all customers increased by

$211.0 million. The Company acquired Infiltrator Water 

Technologies in


            fiscal 2020 and therefore did not report any Infiltrator Water
            Technologies sales for fiscal 2019.

• International net sales for fiscal 2020 decreased by $12.0 million, or


            7.5%, compared to fiscal 2019. International Pipe sales

decreased by

$14.2 million, attributable to volume decreases, offset by an 

increase


            of $2.2 million in International Allied Product sales.


        •   Allied Products & Other net sales for fiscal 2020 increased $47.9
            million, or 13.5%, compared to fiscal 2019. The increase was due to
            the combination of both volume increases along with favorable price
            and product mix.

Cost of goods sold and Gross profit - Cost of goods sold increased by $299.6 million, or 28.3%, and gross profit decreased by $10.5 million, or 3.2%, in fiscal 2020 compared to fiscal 2019. The decrease in gross profit was primarily due to the ESOP special dividend compensation expense of $168.6 million allocated to Cost of goods sold. Gross profit excluding Infiltrator Water Technologies and ESOP special dividend compensation, referred to as organic gross profit, a non-GAAP measure, increased by 23.6%.

        •   Pipe gross profit increased primarily due to the increase in volume
            sold, offset by the decrease in the price and product mix of net sales
            discussed above. The increase in Pipe gross profit was also
            attributable to lower material and transportation costs, which was
            partially offset by higher labor and overhead costs


        •   The Company acquired Infiltrator Water Technologies in fiscal 2020 and
            therefore did not report and Infiltrator Water Technologies gross
            profit for fiscal 2019.

• International gross profit decreased primarily due to the decreased


            net sales discussed above partially offset by decreased

material and


            transportation costs.


• Allied Products & Other gross profit increased primarily due to the


            increase in net sales discussed above.


Selling expenses - Selling expenses for fiscal 2020 as a percentage of net sales were consistent with fiscal 2019.



General and administrative expenses - General and administrative expenses for
fiscal 2020 increased $64.6 million from the prior year. The increase was
primarily due to an increase of $22.2 million in transaction costs primarily
related to the Acquisition, $13.4 million in general and administrative expenses
at Infiltrator Water Technologies, $16.0 million increase in salary, bonus, and
stock-based compensation expenses to support growth and $3.2 million of
strategic growth and operational improvement initiative expenses.

Selling, general and administrative - ESOP special dividend compensation - In
fiscal 2020, ESOP special dividend compensation expense of $78.1 million was
allocated to selling, general and administrative expenses.

Loss on disposal of assets and costs from exit and disposal activities - In the
fiscal year ended March 31, 2020, we recorded $5.3 million of expense related to
loss on disposal of assets and costs from exit and disposal activities compared
to $3.6 million in the year ended March 31, 2019. The increase is primarily due
to $2.6 million of Acquisition related severance and other costs. See "Note 2.
Loss on Disposal of Assets and Costs from Exit and Disposal Activities" for
additional discussion.

Intangible amortization - Intangible amortization increased as a percentage of net sales primarily due to the addition of intangible assets related to the Acquisition.



Interest expense - Interest expense increased $64.1 million in fiscal 2020 as
compared to fiscal 2019. The increase was primarily due to $33.2 million of the
write-off of deferred financing costs and $4.2 million prepayment penalty from
the extinguishment of debt instruments. The remainder of the increase was due to
increased debt levels offset by changes in interest rates. See "Note 13. Debt"
for additional discussion.

Derivative losses (gains) and other expense (income), net - Derivative losses
(gains) and other expenses (income), net, decreased by $2.4 million for fiscal
2020 compared to fiscal 2019. The decrease is primarily due to changes in
realized and unrealized diesel hedges.

Income tax expense - For the fiscal years ended March 31, 2020 and 2019, we had
effective tax rates of (7.9%) and 26.9%, respectively. The decrease in the
effective tax rate was primarily due to stock appreciation from the additional
ESOP shares allocated and the Acquisition. See "Note 18. Income Taxes" for
additional information.

Equity in net (income) loss of unconsolidated affiliates - Equity in net
(income) loss of unconsolidated affiliates represents our proportionate share of
income or loss attributed to our unconsolidated joint venture in which we have
significant influence, but not control, over operations. The equity in net
(income) loss of unconsolidated affiliates increased to $1.9 million income for
fiscal 2020 from a $0.1 million loss for fiscal 2019. Prior to the acquisition
of the noncontrolling interest of Baysaver in fiscal 2019, our proportionate
share of income or loss in BaySaver was included in equity in net (income) loss
of unconsolidated affiliates.

Net income attributable to noncontrolling interest - Income attributable to noncontrolling interest decreased by $2.3 million from net income of $3.7 million in fiscal 2019 to $1.4 million in fiscal 2020. The change is primarily attributable to fluctuations in the profitability of ADS Mexicana.

        •   Pipe net sales to all customers for fiscal 2019 increased by $23.9
            million, or 2.8% compared to fiscal 2018. The increase was due to
            price increases and changes in product mix of $49.3 million partially
            offset by a pipe volume decrease of $15.9 million.

• International net sales for fiscal 2019 increased by $4.7 million, or


            3.0%, compared to fiscal 2018. The decrease was primarily due to an
            increase in international pipe sales of $3.6 million, or 3.0%, which
            was primarily attributable to price increases and changes in

product


            mix, and a $1.1 million increase in international Allied

Products &
            Other net sales.

• Pipe gross profit increased primarily due to the price increases and


            changes in product mix, offset by the decrease in pipe volumes
            discussed above. The increase in Pipe net sales were offset by 

an


            increase in material and transportation costs and increased 

labor and


            overhead.


        •   International gross profit increased $6.2 million, or 24.7%, for
            fiscal 2019 as compared to fiscal 2018 primarily due to decreased
            labor and overhead and the gross profit impact of the net sales
            increase discussed above. These increases were offset by an increase
            in material and transportation costs.


        •   Allied Products & Other gross profit increased primarily due to the
            increase in net sales discussed above and lower labor and overhead
            costs.

Selling expenses - Selling expenses for fiscal 2019 as a percentage of net sales were consistent with fiscal 2018.



General and administrative expenses - General and administrative expenses for
fiscal 2019 decreased as a percentage of net sales by 90 basis points over
fiscal 2018. The decrease was primarily due to a decrease in professional and
legal fees of $10.7 million resulting from decreased restatement costs and a
legal settlement of $2.0 million in fiscal 2018. The decrease was offset by an
increase in salaries and benefits of $4.4 million due to increased headcount to
support growth.

Loss on disposal of assets and costs from exit and disposal activities - In the
fiscal year ended March 31, 2019, we recorded $1.6 million of expense related to
restructuring activities, including closing one underutilized manufacturing
facility. In addition, we recorded a loss on other disposals and partial
disposals of property, plant and equipment of approximately $2.0 million. In the
fiscal year ended March 31, 2018, we recorded $11.4 million of expense related
to restructuring activities, including closing four underutilized manufacturing
facilities. In addition, we recorded a loss on other disposals and partial
disposals of property, plant and equipment of approximately $3.6 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 in fiscal 2019 compared to fiscal 2018.



Interest expense - Interest expense from our debt and finance lease obligations
increased $3.4 million, or 22.0%, in fiscal 2019 as compared to fiscal 2018.
Interest expense increased primarily due to a $4.5 million change in mark to

market losses related to our interest rate swaps. This increase was offset by a
decrease in our average overall outstanding debt of $49.6 million, or 23.9%, for
fiscal 2019 compared to the average balance for fiscal 2018.

Derivative gains and other income, net - Derivative gains and other income, net,
decreased to gains of $0.8 million in fiscal 2019 compared to gains of
$4.0 million in fiscal 2018. The decrease in derivative gains and other income,
net is primarily due to other non-operating income of $3.0 million for fiscal
2018.

Income tax expense - For the fiscal years ended March 31, 2019 and 2018, we had
effective tax rates of 26.9% and 14.8%, respectively. The increase in the
effective tax rate was primarily due to the impact of tax reform items and other
discrete items. See "Note 18. Income Taxes" for additional information.

Equity in net loss of unconsolidated affiliates - Equity in net loss of
unconsolidated affiliates decreased $0.6 million to a net loss of $0.1 million
for fiscal 2019 compared to a net loss of $0.7 million during fiscal 2018. We
are no longer invested in Tigre-ADS USA and therefore no longer recognizing a
proportionate share of Tigre-ADS USA net losses. In addition, net income in the
South American Joint Venture decreased to a net loss.

Net income attributable to noncontrolling interest - Income attributable to noncontrolling interest remained relatively flat as a percentage of net sales in fiscal 2019 compared to fiscal 2018.

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 convertible preferred stock and 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.

The following table presents key liquidity metrics utilized by management. The
table includes the Non-GAAP measure, Free cash flow, which is further discussed
and defined above.

subsidiaries. We continue to evaluate our strategy regarding foreign cash, but
our earnings in foreign subsidiaries still remain indefinitely reinvested.

Debt and Equity Financing Transactions



As further described below, during the fiscal year ended March 31, 2020, the
Company and certain of its subsidiaries entered into a series of transactions
that resulted in the refinancing of the existing external borrowings of the
Company with the new financings, as well as the completion of an underwritten
public offering of common stock. These financing activities were in connection
with the completion of the Acquisition of Infiltrator Water Technologies.

On July 29, 2019, the Company repaid in full all its outstanding indebtedness
and other obligations under the Shelf Note Agreement totaling $104.4 million by
using borrowings from the Company's existing credit facility under the PNC
Credit Agreement. Concurrently with the repayment, all security interests and
liens securing the Shelf Note Agreement were terminated and released, and the
Shelf Note Agreement was terminated.

On July 31, 2019, the Company entered into the Base Credit Agreement with
Barclays Bank PLC, as administrative agent and the several lenders from time to
time party thereto. The Company borrowed under the Credit Agreement and the
funds were used to (i) finance the Merger Consideration for the acquisition of
Infiltrator Water Technologies, (ii) repay the total outstanding amount under
the existing PNC Credit Agreement, (iii) repay outstanding amounts of existing
indebtedness incurred by Infiltrator Water Technologies under its outstanding
credit facility in effect prior to the Acquisition, and (iv) pay certain
transaction fees and expenses associated with the Acquisition and the Credit
Agreement.

Thereafter, on the Acquisition Closing Date, using borrowings of the Bridge Loan
Facility and Bridge Revolving Facility under the Bridge Credit Facility, the
Company repaid in full all its indebtedness and other obligations under the PNC
Credit Agreement totaling $239.2 million. Concurrently with the repayment, all
security interests and liens securing the PNC Credit Agreement were terminated
and released and the PNC Credit Agreement was terminated.

On September 10, 2019, the Company closed the underwritten public offering of
common stock (the "Common Stock Offering") and received net proceeds of
approximately $293.6 million after deducting underwriting discounts and offering
expenses, the proceeds of which were used in part to repay outstanding
borrowings under the Bridge Credit Facility. On September 23, 2019, the Company
issued $350.0 million aggregate principal amount of its Senior Notes, the
proceeds of which were used in part to repay outstanding borrowings under the
Bridge Credit Facility.

On September 24, 2019, the Company entered into the Senior Secured Credit
Facility that amended certain pricing and related terms under the Base Credit
Agreement. In connection with the Senior Secured Credit Facility, the Company
also prepaid outstanding borrowings under the Term Loan Facility of the Senior
Secured Credit Facility in an aggregate principal amount of $600 million.

Working Capital and Cash Flows



During fiscal 2020, our net increase in cash amounted to $165.3 million compared
to a net decrease of $8.7 million during fiscal 2019. Our sources of funds in
fiscal 2020 were primarily driven by borrowings under the Term Loan Facility,
Senior Notes and Revolving Credit Facility, proceeds from our Common Stock
Offering and an increase in cash provided by operating activities. Our use of
cash during fiscal 2020 was primarily related to the Acquisition and repayment
of our previous debt arrangements. Our source of funds in fiscal 2019 was
primarily driven by an increase in cash provided by operating activities due to
increased income from continuing operations and increased deferred tax
liabilities. Additionally, repayments of our long-term debt and revolving credit
facility, cash dividend payments and payments of finance lease obligations
impacted our cash position.

As of March 31, 2020, we had $415.7 million in liquidity, including $174.2 million of cash, $241.5 million in borrowings available under our Revolving Credit Facility, excluding $8.5 million of outstanding letters of credit. We believe that our cash on hand, together with the availability of borrowings under our Revolving Credit Facility and cash generated from operations, will be sufficient to meet our working capital requirements, anticipated capital expenditures, scheduled interest payments on our indebtedness and dividend payment requirement for our convertible preferred stock for at least the next twelve months.

As of March 31, 2020, we had consolidated indebtedness (excluding finance lease
obligations) of approximately $1,099.7 million, an increase of $862.9 million
compared to March 31, 2019.

Working Capital - Working capital is an indication of liquidity and potential
need for short-term funding. We define working capital as current assets less
current liabilities.

Working capital increased to $428.0 million as of March 31, 2020, from
$260.2 million as of March 31, 2019, primarily due to an increase in cash of
$165.3 million. The Company holds a favorable cash position and drew down $100
million prior to March 31, 2020 on its revolving credit facility out of an
abundance of caution to ensure liquidity during the COVID-19 pandemic.

Working capital increased to $260.2 million as of March 31, 2019, from $237.2 million as of March 31, 2018, primarily due to an increase in receivables of $15.0 million and a decrease in accounts payable of $11.9 million.



Operating Cash Flows - During fiscal 2020, cash provided by operating activities
was $306.2 million as compared with cash provided by operating activities of
$151.7 million for fiscal 2019. Cash flow from operating activities during
fiscal 2020 was primarily impacted by changes in working capital, including
improved collections from accounts receivable, faster inventory turns and
extension of terms of our accounts payable.

During fiscal 2019, cash provided by operating activities was $151.7 million as
compared with cash provided by operating activities of $137.1 million for fiscal
2018. Cash flow from operating activities during fiscal 2019 was primarily
impacted by increased income from continuing operations including decreased
restructuring costs.

Investing Cash Flows - During fiscal 2020, cash used for investing activities
was $1,150.5 million. The increase in cash used for investing activities was
primarily due to the Acquisition of Infiltrator Water Technologies, net of cash
acquired. Capital expenditures was $67.7 million compared to $43.4 million in
fiscal 2019.

During fiscal 2019, cash used for investing activities was $42.5 million, primarily due to $43.4 million for capital expenditures and additions to capitalized software.



During fiscal 2018, cash used for investing activities was $30.4 million,
primarily due to $41.7 million for capital expenditures and additions to
capitalized software, and $2.0 million for the acquisition of Duraslot, Inc. The
Company also received $13.6 million of proceeds from the sale of corporate-owned
life insurance.

We currently anticipate that we will make capital expenditures of approximately
$60 to 65 million in fiscal 2021. Such capital expenditures are expected to be
financed using funds generated by operations.

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 ESOP committee
can direct the shares of redeemable convertible preferred stock owned by the
ESOP to 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 16. Employee Benefit Plans", 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.

Following the repayment of the ESOP loan discussed above, the ESOP's conversion
of redeemable convertible preferred stock into common stock will impact on the
Company's net income, net income per share and common shares outstanding as
follows (with the outstanding shares of common stock being approximately 30%
greater after conversion):

Impact on Net Income - Absent any other participating securities, the Company
will no longer be required to apply the two-class method to determine Net income
per share once all of the redeemable convertible preferred stock is converted
into common stock. After the preferred shares are fully allocated upon the
repayment of the ESOP loan and all of the redeemable convertible preferred stock
is converted into common stock, the Company will no longer incur the fair value
of ESOP deferred compensation attributable to the shares of redeemable
convertible preferred shares.

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.

a discussion of the Company's financing transactions, including the Secured Bank
Loans, the Senior Notes and the Company's finance lease obligations.

Financing Transactions



PNC Term Loans - On June 22, 2017, we entered into the PNC Credit Agreement,
which amends and restates the original agreement dated as of June 12, 2013,
which provided us with a $550 million revolving credit facility, which is more
fully described in our Fiscal 2019 Form 10-K. On the Closing Date, using
borrowings of the new Term Loan Facility the Company repaid in full all of its
and its subsidiaries indebtedness and other obligations totaling $239.2 million
under the PNC Credit Agreement. Concurrently with the repayment, all security
interests and liens held by the Collateral Agent (as defined in the PNC Credit
Agreement) securing the PNC Credit Agreement were terminated and released and
the PNC Credit Agreement was terminated.

ADS Mexicana Revolving Credit Facility - The Company and ADS Mexicana entered
into an Intercompany Revolving Credit Promissory Note (the "Intercompany Note")
with a capacity of $12.0 million on June 22, 2018. 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 March 31, 2020, there were
no borrowings under the Intercompany Note.

Prudential Senior Notes - On June 22, 2017, we entered into the Shelf Note
Agreement to provide for the issuance of secured senior notes to the Shelf Note
Lenders from time to time in the aggregate principal amount of up to $175
million, which is more fully described in our Fiscal 2019 Form 10-K. On July 29,
2019, the Company repaid in full all of its and its subsidiaries indebtedness
and other obligations totaling $104.4 million under the Shelf Note
Agreement using borrowings from the PNC Credit Agreement as in effect as of July
29, 2019. Concurrently with the repayment, the Prudential Shelf Noteholders
authorized and directed PNC Bank, National Association, in its capacity as
Collateral Agent (as defined in the Shelf Note Agreement) to release the
security interests and liens securing the Shelf Note Agreement and the Shelf
Note Agreement was terminated.

Bridge Credit Facility - On July 31, 2019, we entered into the Base Credit
Agreement with Barclays Bank PLC, as administrative agent and the several
lenders from time to time party thereto. The Base Credit Agreement provides for
up to $1.3 billion as a Term Loan Facility, up to $350 million as a Revolving
Facility, up to $50 million as an L/C Facility and up to $50 million, as a
sublimit of the Revolving Facility.

On July 31, 2019, the Company borrowed under the Base Credit Agreement which was
used to (i) finance the Merger Consideration paid in connection with the closing
of the acquisition of Infiltrator Water Technologies by us which occurred on
July 31, 2019 (the "Merger"), (ii) and repay the total outstanding amount as of
the Closing Date under the PNC Credit Agreement, (iii) repay outstanding amounts
of existing indebtedness incurred by Infiltrator Water Technologies under its
outstanding credit facility in effect prior to the Acquisition, and (iv) pay
certain transaction fees and expenses associated with the Acquisition and the
Base Credit Agreement.

New Senior Secured Credit Facility - On September 24, 2019, the joint lead
arrangers informed the Company that the parties had successfully completed a
syndication of the remaining balance of the Bridge Credit Facility. The Senior
Secured Credit Facility provided for a Term Loan Facility with an initial
aggregate amount of $700 million, up to $350 million as a Revolving Facility,
and up to $50 million as a letter of credit facility, as a sublimit of the
Revolving Facility.

The Term Loan Facility must has an amortization feature equal to 1% of the original $700 million balance paid in equal quarterly installments commencing on January 1, 2020 and continuing on the first day of each consecutive

April, July, October and January thereafter. To the extent not previously paid,
all then-outstanding amounts under the Term Loan Facility are due and payable on
the maturity date of the Term Loan Facility, which is September 26, 2026.
Borrowings under the Revolving Facility are available beginning on the Closing
Date and, to the extent not previously paid, all then-outstanding amounts under
the Revolving Facility are due and payable on the maturity date of the Revolving
Facility, which is September 29, 2024.

The Senior Secured Credit Facility includes customary representations, warranties, covenants and events of default.



At the option of the Company, borrowings under the Term Loan Facility and under
the Revolving Facility (subject to certain limitations) bear interest at either
a base rate (as determined pursuant to the Senior Secured Credit Facility) or at
a Eurocurrency Rate, based on LIBOR (as defined in the Senior Secured Credit
Facility), plus the applicable margin as set forth therein from time to time. In
the case of the Revolving Facility, the applicable margin is based on the
Company's consolidated senior secured net leverage ratio (as defined in the
Senior Secured Credit Facility). All borrowings under the Term Loan Facility
used to finance the Merger Consideration as described above initially bear
interest at a Eurocurrency Rate (as defined in the Senior Secured Credit
Facility).

The Company's obligations under the Credit Agreement have been secured by
granting a first priority lien on substantially all of the Company's assets
(subject to certain exceptions and limitations), and each of StormTech, LLC,
Advanced Drainage of Ohio, Inc. and Infiltrator Water Technologies, LLC
(collectively the "Guarantors") has agreed to guarantee the obligations of the
Company under the Senior Secured Credit Facility and to secure the obligations
thereunder by granting a first priority lien in substantially all of such
Guarantor's assets (subject to certain exceptions and limitations).

The Senior Secured Credit Facility requires, if the aggregate amount of
outstanding exposure under the Revolving Facility exceeds $122.5 million at the
end of any fiscal quarter, the Company to maintain a consolidated senior secured
net leverage ratio (commencing with the fiscal quarter ending March 31, 2020)
not to exceed 4.25 to 1.00 for any four consecutive fiscal quarter periods.

The Senior Secured Credit Facility also includes other covenants, including
negative covenants that, subject to certain exceptions, limit the Company's and
its restricted subsidiaries' (as defined in the Senior Secured Credit Facility)
ability to, among other things: (i) incur additional debt, including guarantees;
(ii) create liens upon any of their property; (iii) enter into any merger,

non-ordinary course sale of assets and certain casualty or condemnation events;
and (iii) 100% of the net cash proceeds of indebtedness not permitted to be

Issuance of Senior Notes due 2027 - On September 23, 2019, the Company issued
$350.0 million aggregate principal amount of its Senior Notes, pursuant to the
Indenture among the Company, the Guarantors and the Trustee. The Senior Notes

Senior Secured Credit Facility. The Senior Notes were offered and sold either to
persons reasonably believed to be "qualified institutional buyers" pursuant to
Rule 144A under the Securities Act or to persons outside the United States under
Regulation S of the Securities Act.

Interest on the Senior Notes will be payable semi-annually in cash in arrears on
March 31 and September 30 of each year, commencing on March 31, 2020, at a rate
of 5.000% per annum. The Senior Notes will mature on September

Off-Balance Sheet Arrangements



We do not have any off-balance sheet arrangements, with the exception of the
guarantee of 50% of certain debt of our unconsolidated South American Joint
Venture, as further discussed in "Note 12. Related Party Transactions" of our
Consolidated Financial Statements included in "Item 8. Financial Statements and
Supplementary Data," of this Form 10-K. Our maximum potential obligation under
this guarantee totals $11 million as of March 31, 2020. The maximum borrowing
permitted under the South American Joint Venture's credit facility is $22
million. As of March 31, 2020, our South American Joint Venture had
approximately $9.3 million of outstanding debt subject to our guarantee,
resulting in our guarantee of 50%, or $4.7 million, of that amount. 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



Our discussion and analysis of financial condition and results of operations are
based on our consolidated financial statements, which have been prepared in
accordance with GAAP. The preparation of the consolidated financial statements
requires management to make estimates and judgments that affect the reported
amounts in our consolidated financial statements and accompanying notes.

Certain of our accounting policies involve a higher degree of judgment and
complexity in their application, and therefore, represent the critical
accounting policies used in the preparation of our financial statements. If
different assumptions or conditions were to prevail, the results could be
materially different from our reported results. We believe the following
accounting policies may involve a higher degree of judgment and complexity in
their application and represent the critical accounting policies used in the
preparation of our financial statements. For additional discussion of our
significant accounting policies, see "Note 1. Background and Summary of
Significant Accounting Policies" to our consolidated financial statements
included in "Item 8. Financial Statements and Supplementary Data" included in
this Form 10-K.
