forefront of evolving industry trends and consumer demands, which in turn has allowed us to become a market leader across our core product categories.

Basis of Presentation



Our Consolidated Financial Statements in this Annual Report have been derived
from our accounts and those of our wholly-owned subsidiaries. Our Consolidated
Financial Statements are based on a fiscal year ending September 30.

In January 2020, we acquired Return Polymers, Inc. The assets acquired and
liabilities assumed in connection with this acquisition were included in our
consolidated balance sheet as of September 30, 2020 and in our consolidated
statement of comprehensive income (loss) and statement of cash flow beginning
from the effective date of the acquisition in January 2020. The results of
operations of Return Polymers are included in our Residential segment.

Initial Public Offering



On June 16, 2020, we completed our IPO of our Class A common stock, in which we
sold 38,237,500 shares, including 4,987,500 shares pursuant to the underwriters'
over-allotment option. The shares began trading on the New York Stock Exchange
on June 12, 2020 under the symbol "AZEK". The shares were sold at an IPO price
of $23.00 per share for net proceeds to us of approximately $819.7 million,
after deducting underwriting discounts and commissions of $50.6 million and
offering expenses of approximately $9.2 million payable by us. In addition, we
used the net proceeds to redeem $350.0 million in aggregate principal of our
then-outstanding 2025 Senior Notes, $70.0 million of our then-outstanding
principal amount under the Revolving Credit Facility and effected a
$337.7 million prepayment of our then-outstanding principal amount under the
Term Loan Agreement.

Secondary Offerings

On September 15, 2020, we completed an offering of 28,750,000 shares of Class A
common stock, including the exercise in full by the underwriters of their option
to purchase up to 3,750,000 additional shares of Class A common stock, at a
public offering price of $33.25 per share. All of the shares were sold by
certain of our stockholders, or the Selling Stockholders. We did not receive any
of the proceeds from the sale of the shares by the Selling Stockholders. The
offering expenses of approximately $1.4 million is payable by us and recorded in
"Other general expenses" within the Consolidated Statements of Comprehensive
Income (Loss). Immediately subsequent to the closing of the secondary offering,
our sole stockholder of our Class B common stock converted 33,068,863 shares of
its Class B common stock into shares of Class A common stock.

On January 26, 2021, we completed an offering of 23,000,000 shares of Class A
common stock, par value $0.001 per share, including the exercise in full by the
underwriters of their option to purchase up to 3,000,000 additional shares of
Class A common stock, at a public offering price of $40.00 per share. The shares
were sold by certain of the Selling Stockholders. We did not receive any of the
proceeds from the sale of the shares by those Selling Stockholders. In
connection with the offering we incurred approximately $1.2 million in expenses.

On June 1, 2021, we completed an offering of 17,250,000 shares of Class A common
stock, par value $0.001 per share, including the exercise in full by the
underwriters of their option to purchase up to 2,250,000 additional shares of
Class A common stock, at a public offering price of $43.50 per share. The shares
were sold by certain of the Selling Stockholders. We did not receive any of the
proceeds from the sale of the shares by those Selling Stockholders. In
connection with the offering we incurred approximately $1.1 million in expenses.

Key Factors Affecting Our Results of Operations



Our results of operations and financial condition are affected by the following
factors, which reflect our operating philosophy and continued focus on driving
material conversion to our low-maintenance, engineered products in each of our
markets.

Volume of Products Sold

Our net sales depend primarily on the volume of products we sell during any given period, and volume is affected by the following items:

• Economic conditions: Demand for our products is significantly affected by

a number of economic factors impacting our customers and consumers. For

example, demand for products sold by our Residential segment is driven

primarily by home repair and remodeling activity and, to a lesser extent,

new home construction activity. The residential repair and remodeling


        market depends in part on home equity financing, and accordingly, the
        level of equity in homes will affect consumers' ability to obtain a home
        equity line of credit and engage in renovations that would result in
        purchases of our


                                       38

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

products. Demand for our products is also affected by the level of

interest rates and the availability of credit, consumer confidence and

spending, housing affordability, demographic trends, employment levels and

other macroeconomic factors that may influence the extent to which

consumers engage in repair and remodeling projects to enhance the outdoor


        living spaces of their homes. Sales by our Commercial segment in the
        institutional construction market are affected by amounts available for

expenditures in school construction, military bases and other public

institutions, which depend in part on the availability of government

funding and budgetary priorities. Sales of our engineered polymer

materials in our industrial OEM markets are also affected by macroeconomic

factors, in particular gross domestic product levels and levels of

industrial production. Changes in these economic conditions can impact the

volume of our products sold during any given period.

• Material conversion: We have continued to increase sales of our products

through our focused efforts to drive material conversion and market

penetration of our products. We believe that there is a long-term trend

toward material conversion from traditional materials, such as wood, to

the low-maintenance, engineered materials we produce. We believe that our

products offer a compelling value proposition due to their enhanced

durability and lower maintenance costs compared to products manufactured

from traditional materials, and we anticipate that sales of our products

will continue to benefit from material conversion. The success of our

efforts to drive conversion during any given period will impact the volume

of our products sold during that period.

• Product innovation: We continue to develop and introduce innovative


        products to accelerate material conversion and expand our markets. We
        believe that new products will enhance our ability to compete with
        traditional materials at a variety of price points, and we expect to
        continue to devote significant resources to developing innovative new
        products. The volume of our products sold during a given period will

depend in part on our successfully introducing new products that generate

additional demand as well as the extent to which new products may impact

our sales of existing products.

• Marketing and distribution: Demand for our products is influenced by our

efforts to expand and enhance awareness of our premium brands and the

benefits of our products as well as to drive continued material

conversion. Within our Residential segment, we sell our products through a

national network of more than 4,200 dealers, more than 35 distributors and

multiple home improvement retailers providing extensive geographic

coverage enabling us to effectively serve contractors across the United

States and Canada. Within our Commercial segment, we sell our products

through a widespread distribution network as well as directly to OEMs. Our

customer-focused sales organization generates pull-through demand for our

products by driving increased downstream engagement with consumers and key

influencers such as architects, builders and contractors and by focusing

on strengthening our position with dealers and growing our presence in

retail. Our volume of product sales in a given period will be impacted by

our ability to raise awareness of our brands and products.

Pricing



In general, our pricing strategy is to price our products at a premium relative
to competing materials based on the value proposition they provide, including
lower maintenance and lifetime costs. Our pricing strategy differs between our
two operating segments as follows:

• Residential: Prices for our residential products are typically set

annually, however recent market trends have warranted repricing on a more


        frequent basis, taking into account current and anticipated changes in
        input costs, market dynamics and new product introductions by us or our
        competitors.


    •   Commercial: A number of our commercial product sales, such as those
        related to our partitions and lockers product lines, are customized by
        order, and, therefore, these products are typically priced based on the

nature of the particular specifications ordered. For other commercial


        products, such as various Vycom product lines, we maintain standard
        pricing lists that we review and change periodically as the market
        demands.


Cost of Materials

Raw material costs, including costs of petrochemical resins, reclaimed
polyethylene and PVC material, waste wood fiber and aluminum, represent a
majority of our cost of sales. The cost of petrochemical resins used in our
manufacturing processes has historically varied significantly and has been
affected by changes in supply and demand and in the price of crude oil. In
addition, the price of reclaimed polyethylene material, waste wood fiber,
aluminum, other additives (including modifiers, TiO2 and pigments) and other raw
materials fluctuates depending on, among other things, overall market supply and
demand and general business conditions. We have long-standing relationships as
well as guaranteed supply contracts with some of our key suppliers but, other
than certain contracts with prices determined based on the current index price,
we have no fixed-price contracts with any of our major vendors. Under our
guaranteed supply contracts, the prices are either established annually based on
a discount to the then-current market prices or, for purchase orders, based on
market rates in effect when the orders become effective. Prices for spot market
purchases are negotiated on a continuous basis in line with the market at the
time. During fiscal year 2021, we experienced significant increases in

                                       39

--------------------------------------------------------------------------------
the cost of our raw materials due to factors such as global and domestic supply
chain disruptions, extreme weather events, including Winter Storm Uri, and the
direct and indirect effects of the COVID-19 pandemic. While we seek to mitigate
the effects of increases in raw material costs by broadening our supplier base,
increasing our use of recycled material and scrap, reducing waste and exploring
options for material substitution without sacrificing quality, we anticipate
that the increased raw material prices and shortages of raw materials that we
experienced in fiscal year 2021 may continue for the foreseeable future. We have
not entered into hedges with respect to our raw material costs at this time, but
we may choose to enter into such hedges in the future.

Product Mix



We offer a wide variety of products across numerous product lines within our
Residential and Commercial segments, and these products are sold at different
prices, are composed of different materials and involve varying levels of
manufacturing complexity. In any particular period, changes in the volume of
particular products sold and the prices of those products relative to other
products will impact our average selling price and our cost of sales. For
example, the gross margins of our Residential segment significantly exceed the
gross margins of our Commercial segment. In addition to the impacts attributable
to product mix as between the Residential and Commercial segments, our results
of operations are impacted by the relative margins associated with individual
products within our Residential and Commercial segments, which vary among
products. As we continue to introduce new products at varying price points to
compete with products made with wood or other traditional materials across a
wide range of prices, our overall gross margins may vary from period to period
as a result of changes in product mix and different margins for our higher and
lower price point offerings. We may choose to introduce new products with
initially lower gross margins with the expectation that those margins will
improve over time as we improve our manufacturing efficiency for those products.
In addition, our product mix and our gross margins may be impacted by our
marketing decisions in a particular period as well as the rebates and incentives
that we may extend to our customers in a particular period. We also continue to
seek to enhance our gross margins by improving manufacturing efficiency across
our operations, including by investing in, and expanding, our recycling
capabilities and implementing initiatives to more efficiently use scrap and to
reduce waste. Our success in achieving margin improvements through these
initiatives may vary due to changes in product mix as different products benefit
to different degrees from these initiatives.

Seasonality



Although we generally have demand for our products throughout the year, our
sales have historically experienced some seasonality. We have typically
experienced moderately higher levels of sales of our residential products in the
second fiscal quarter of the year as a result of our "early buy" sales and
extended payment terms typically available during the second fiscal quarter of
the year. As a result of these extended payment terms, our accounts receivable
have typically reached seasonal peaks at the end of the second fiscal quarter of
the year, and our net cash provided by operating activities has typically been
lower in the second fiscal quarter relative to in other quarters. Our sales are
also generally impacted by the number of days in a quarter or a year that
contractors and other professionals are able to install our products. This can
vary dramatically based on, among other things, weather events such as rain,
snow and extreme temperatures. We have generally experienced lower levels of
sales of our residential products in the first fiscal quarter due to adverse
weather conditions in certain markets, which typically reduce the construction
and renovation activity during the winter season. In addition, we have
experienced higher levels of sales of our bathroom partition products and our
locker products during the second half of our fiscal year, which includes the
summer months when schools are typically closed and therefore are more likely to
undergo remodel activities.

COVID-19

Since the onset of the COVID-19 pandemic, we have been focused on protecting our
employees' health and safety, meeting our customers' needs as they navigate an
uncertain financial and operating environment, working closely with our
suppliers to protect our ongoing business operations and rapidly adjusting our
short-, medium- and long-term operational plans to proactively and effectively
respond to the current and potential future public health crises. While the
COVID-19 pandemic and its direct and indirect effects present very serious
concerns for our business and operations, our employees and their families, our
customers and our suppliers, we believe that we have adapted and continue to
adapt well to the wide ranging changes that the global economy continues to
undergo, and we remain confident that we will continue to maintain business
continuity, produce and sell our products safely and in compliance with
applicable laws and governmental orders and mandates, maintain our robust and
flexible supply chains and be in a strong position to maintain financial
flexibility even in the event of a potentially extended economic downturn. This
discussion and analysis includes periods prior to the outbreak of the COVID-19
pandemic.

Although we have implemented measures to mitigate the impact of the COVID-19
pandemic on our business, financial condition and results of operations, we
expect that these measures may not fully mitigate the impact of the COVID-19
pandemic on our business, financial condition and results of operations. We
cannot predict the degree to, or the period over, which we will be affected by
the pandemic and resulting governmental and other measures. We expect that the
direct and indirect economic effects of the COVID-19 pandemic will likely
continue to affect demand for our products in the foreseeable future. As the
COVID-19 pandemic

                                       40

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

continues, it may also have the effect of heightening many of the risks described in "Risk Factors" in this Annual Report. See "Risk Factors" for a further discussion of the adverse impacts of the COVID-19 pandemic on our business.

Acquisitions



Throughout our history, we have made selected acquisitions, and we expect to
continue to strategically pursue acquisitions to enhance our market position,
supplement our product and technology portfolios and increase the diversity of
our business.

Year Ended September 30, 2021, Compared with Year Ended September 30, 2020

Net Sales



Net sales for the year ended September 30, 2021 increased by $279.7 million, or
31.1%, to $1,179.0 million from $899.3 million for the year ended September 30,
2020. The increase was primarily attributable to higher sales in both our
Residential and Commercial segments. Net sales for the year ended September 30,
2021 increased for our Residential segment by 35.4% and increased for our
Commercial segment by 5.3%, in each case as compared to the prior year.

Cost of Sales



Cost of sales for the year ended September 30, 2021 increased by $185.8 million,
or 30.8%, to $789.0 million from $603.2 million for the year ended September 30,
2020, primarily due to increased costs on higher sales volumes and higher costs
of raw materials and manufacturing.

Gross Profit



Gross profit for the year ended September 30, 2021 increased by $93.9 million,
or 31.7%, to $390.0 million from $296.1 million for the year ended September 30,
2020. Gross margin increased to 33.1% for the year ended September 30, 2021
compared to 32.9% for the year ended September 30, 2020. The  increase in gross
profit was driven by the strong results in the Residential and Commercial
segments which include pricing and manufacturing productivity, partially offset
by higher costs.

Selling, General and Administrative Expenses

Selling, general and administrative expenses decreased by $64.1 million, or 20.8%, to $244.2 million, or 20.7% of net sales, for the year ended September 30, 2021 from $308.3 million, or 34.3% of net sales, for the year ended September 30, 2020. The decrease was primarily attributable to lower stock-based compensation expense, partially offset by higher personnel costs, professional fees, marketing expenses and ongoing public company expenses.

for the year ended September 30, 2021 from $71.2 million for the year ended
September 30, 2020. Interest expense decreased primarily due to the reduced
principal amount outstanding under our Term Loan Agreement, the redemption of
our 2021 Senior Notes during the year ended September 30, 2020 and lower average
interest rates during the year ended September 30, 2021, when compared to the
year ended September 30, 2020.

Loss on Extinguishment of Debt



Loss on extinguishment of debt decreased by $37.6 million for the year ended
September 30, 2021 as a result of the extinguishment of the 2025 Senior Notes
and the 2021 Senior Notes during the year ended September 30, 2020. For more
information regarding the 2021 Senior Notes and the 2025 Senior Notes, see Note
7 "Debt" to our Consolidated Financial Statements included elsewhere in this

13.2%, to $899.3 million from $794.2 million for the year ended September 30,
2019. The increase was primarily attributable to higher sales in our Residential
segment. Net sales for the year ended September 30, 2020 increased for our
Residential segment by 17.7% and decreased for our Commercial segment by 7.7%,
in each case as compared to the prior year.

Cost of Sales



Cost of sales for the year ended September 30, 2020 increased by $62.2 million,
or 11.5%, to $603.2 million from $541.0 million for the year ended September 30,
2019 primarily due to increased costs on higher sales volumes and the impact of
COVID-19 related production costs partially offset by manufacturing
productivity.

Gross Profit



Gross profit for the year ended September 30, 2020 increased by $42.9 million,
or 16.9%, to $296.1 million from $253.2 million for the year ended September 30,
2019. Gross margin increased to 32.9% for the year ended September 30, 2020
compared to 31.9% for the year ended September 30, 2019. The increase in gross
profit was driven by higher Residential segment sales and manufacturing
productivity, partially offset by the impact of COVID-19 related production
costs.

Selling, General and Administrative Expenses



Selling, general and administrative expenses increased by $124.7 million, or
67.9%, to $308.3 million, or 34.3% of net sales, for the year ended
September 30, 2020 from $183.6 million, or 23.1% of net sales, for the year
ended September 30, 2019. The increase was primarily attributable to
$120.5 million of stock-based compensation expense related to our initial public
offering and the accelerated vesting of stock-based compensation expense
resulting from the secondary offering, partially offset by lower marketing and
selling expenses during the initial COVID-19 disruption.

Other General Expenses

Other general expenses which were $8.6 million during the year ended September 30, 2020 and $9.1 million during the year ended September 30, 2019, resulted from the completion of our initial public offering and secondary offering.


                                       42

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

Interest Expense, net



Interest expense, net, decreased by $12.0 million, or 14.5%, to $71.2 million
for the year ended September 30, 2020 from $83.2 million for the year ended
September 30, 2019. Interest expense decreased primarily due to the reduced
principal amount outstanding under our Term Loan Agreement, the redemption of
our 2021 Senior Notes and lower average interest rates during the year ended
September 30, 2020, when compared to the year ended September 30, 2019.

Loss on Extinguishment of Debt

Loss on extinguishment of debt was $37.6 million for the year ended September 30, 2020 as a result of the extinguishment of the 2025 Senior Notes and the 2021 Senior Notes.

Income Tax Expense (Benefit)



Income tax benefit increased by $4.3 million to $8.3 million for the year ended
September 30, 2020 compared to $4.0 million for the year ended September 30,
2019. The increase in our income tax benefit was primarily driven by our pre-tax
net loss, offset by the non-deductible stock-based compensation expense we
recognized, as a result of our initial public offering and secondary offering.

Net Income (Loss)



Net loss increased by $102.0 million to a net loss of $122.2 million for the
year ended September 30, 2020 compared to net loss of $20.2 million for the year
ended September 30, 2019, primarily due to $120.5 million of increased selling,
general and administrative expenses due to the recognition of additional
stock-based compensation expense as a result of our initial public offering and
secondary offering, as well as $37.6 million of expenses related to the
extinguishment of debt.

Segment Results of Operations



We report our results in two segments: Residential and Commercial. The key
segment measures used by our chief operating decision maker in deciding how to
evaluate performance and allocate resources to each of the segments are Segment
Adjusted EBITDA and Segment Adjusted EBITDA Margin. Depending on certain
circumstances, Segment Adjusted EBITDA and Segment Adjusted EBITDA Margin may be
calculated differently, from time to time, than our Adjusted EBITDA and Adjusted
EBITDA Margin, which are further discussed under the heading "Selected
Consolidated Financial Data-Non-GAAP Financial Measures." Segment Adjusted
EBITDA and Segment Adjusted EBITDA Margin represent measures of segment profit
reported to our chief operating decision maker for the purpose of making
decisions about allocating resources to a segment and assessing its performance
and are determined as disclosed in our Consolidated Financial Statements
included elsewhere in this Annual Report consistent with the requirements of the
Financial Accounting Standards Board's, or FASB, Accounting Standards
Codification, or ASC, 280. We define Segment Adjusted EBITDA as a segment's net
income (loss) before income tax (benefit) expense and by adding to or
subtracting therefrom interest expense, net, depreciation and amortization,
stock-based compensation costs, asset impairment and inventory revaluation
costs, business transformation costs, capital structure transaction costs,
acquisition costs, initial public offering costs and certain other costs.
Segment Adjusted EBITDA Margin is equal to a segment's Segment Adjusted EBITDA
divided by such segment's net sales. Corporate expenses, which include selling,
general and administrative costs related to our corporate offices, including
payroll and other professional fees, are not included in computing Segment
Adjusted EBITDA. Such corporate expenses increased by $20.1 million to
$59.7 million for the year ended September 30, 2021 from $39.6 million for the
year ended September 30, 2020, and decreased by $2.7 million to $39.6 million
for the year ended September 30, 2020 from $42.3 million for the year ended
September 30, 2019.

Net Sales



Net sales of the Residential segment for the year ended September 30, 2021
increased by $273.0 million, or 35.4%, to $1,044.1 million from $771.2 million
for the year ended September 30, 2020. The increase was primarily attributable
to higher net sales related to our Deck, Rail & Accessories and Exteriors
businesses.

Net sales of the Residential segment for the year ended September 30, 2020
increased by $115.7 million, or 17.7%, to $771.2 million from $655.4 million for
the year ended September 30, 2019. The increase was primarily attributable to
higher sales in our Deck, Rail and Accessories and Exteriors businesses driven
by continued market growth and success of new products across the portfolio, as
well as the benefit from investments in downstream selling capabilities, retail
expansion and pricing.

Segment Adjusted EBITDA

Segment Adjusted EBITDA of the Residential segment for the year ended
September 30, 2021 increased by $76.5 million, or 32.1% to $314.6 million from
$238.1 million for the year ended September 30, 2020. The increase was mainly
driven by higher sales, pricing, manufacturing productivity, partially offset by
higher raw material costs, manufacturing costs and selling, general and
administrative expenses.

Segment Adjusted EBITDA of the Residential segment for the year ended
September 30, 2020 increased by $49.3 million, or 26.1%, to $238.1 million from
$188.7 million for the year ended September 30, 2019. The increase was mainly
driven by higher sales, net manufacturing productivity improvements, as well as
lower selling, general and administrative expenses, partially offset by COVID-19
related production costs.

Net Sales

Net sales of the Commercial segment increased by $6.8 million, or 5.3%, to
$134.8 million for the year ended September 30, 2021 from $128.1 million for the
year ended September 30, 2020. The increase was primarily attributable to higher
net sales in our Vycom business, partially offset by decreased net sales in our
Scranton Products business.

Net sales of the Commercial segment for the year ended September 30, 2020
decreased by $10.7 million, or 7.7%, to $128.1 million from $138.8 million for
the year ended September 30, 2019. The decrease was primarily driven by lower
sales in our Vycom business, as the effects of COVID-19 impacted certain end
market demands.

Segment Adjusted EBITDA

Segment Adjusted EBITDA of the Commercial segment was $19.3 million for the year ended September 30, 2021, compared to $15.1 million for the year ended September 30, 2020. The increase was driven by higher sales in the Vycom business, pricing and net manufacturing productivity offset by higher raw material costs.



Segment Adjusted EBITDA of the Commercial segment was $15.1 million for the year
ended September 30, 2020 compared to $21.5 million for the year ended
September 30, 2019. The decrease was primarily driven by lower sales in the
Vycom business, partially offset by lower manufacturing costs and reductions in
selling, general and administrative expenses.

Non-GAAP Financial Measures



To supplement our Consolidated Financial Statements prepared and presented in
accordance with generally accepted accounting principles in the United States,
or GAAP, we use certain non-GAAP performance financial measures, as described
below, to provide investors with additional useful information about our
financial performance, to enhance the overall understanding of our past
performance and future prospects and to allow for greater transparency with
respect to important metrics used by our management for financial and
operational decision-making. We are presenting these non-GAAP financial measures
to assist investors in seeing our financial performance from management's view
and because we believe they provide an additional tool for investors to use in
comparing our core financial performance over multiple periods with other
companies in our industry. Our GAAP financial results include significant
expenses that are not indicative of our ongoing operations as detailed in the
tables below.

However, non-GAAP financial measures have limitations in their usefulness to
investors because they have no standardized meaning prescribed by GAAP and are
not prepared under any comprehensive set of accounting rules or principles. In
addition, non-GAAP financial measures may be calculated differently from, and
therefore may not be directly comparable to, similarly titled measures used by
other companies. As a result, non-GAAP financial measures should be viewed as
supplementing, and not as an alternative or substitute for, our Consolidated
Financial Statements prepared and presented in accordance with GAAP.

                                                       Years Ended September 30,

Adjusted Gross Profit Margin                          38.8 %         39.9 %         39.6 %

Adjusted Gross Profit, Adjusted Gross Profit Margin, Adjusted Net Income, Adjusted Diluted EPS, Adjusted EBITDA and Adjusted EBITDA Margin



We define Adjusted Gross Profit as gross profit before depreciation and
amortization, business transformation costs and acquisition costs as described
below. Adjusted Gross Profit Margin is equal to Adjusted Gross Profit divided by
net sales. We define Adjusted Net Income as net income (loss) before
amortization, stock-based compensation costs, business transformation costs,
acquisition costs, initial public offering costs, capital structure transaction
costs and certain other costs as described below. We define Adjusted Diluted EPS
as Adjusted Net Income divided by weighted average common shares
outstanding-diluted, to reflect the conversion or exercise, as applicable, of
all outstanding shares of restricted stock awards, restricted stock units and
options to purchase shares of our common stock. We define Adjusted EBITDA as net
income (loss) before interest expense, net, income tax (benefit) expense and
depreciation and amortization and by adding to or subtracting therefrom items of
expense and income as described below. Adjusted EBITDA Margin is equal to
Adjusted EBITDA divided by net sales. We believe Adjusted Gross Profit, Adjusted
Gross Profit Margin, Adjusted Net Income, Adjusted Diluted EPS, Adjusted EBITDA
and Adjusted EBITDA Margin are useful to investors because they help identify
underlying trends in our business that could otherwise be masked by certain
expenses that can vary from company to company depending on, among other things,
its financing, capital structure and the method by which its assets were
acquired, and can also vary significantly from period to period. We also add
back depreciation and amortization and stock-based compensation because we do
not consider them indicative of our core operating performance. We believe their
exclusion facilitates comparisons of our operating performance on a
period-to-period basis. Therefore, we believe that showing gross profit and net
income, as adjusted to remove the impact of these expenses, is helpful to
investors in assessing our gross profit and net income performance in a way that
is similar to the way management assesses our performance. Additionally, EBITDA
and EBITDA margin are common measures of operating performance in our industry,
and we believe they facilitate operating comparisons. Our management also uses
Adjusted Gross Profit, Adjusted Gross Profit Margin, Adjusted EBITDA and
Adjusted EBITDA Margin in conjunction with other GAAP financial measures for
planning purposes, including as a measure of our core operating results and the
effectiveness of our business strategy, and in evaluating our financial
performance. Management considers Adjusted Gross Profit and Adjusted Net Income
and Adjusted Diluted EPS as useful measures because our cost of sales includes
the depreciation of property, plant and equipment used in the production of
products and the amortization of various intangibles related to our
manufacturing processes.

Adjusted Gross Profit, Adjusted Gross Profit Margin, Adjusted Net Income,
Adjusted Diluted EPS, Adjusted EBITDA and Adjusted EBITDA Margin have
limitations as analytical tools, and you should not consider them in isolation
or as a substitute for analysis of our results as reported under GAAP. Some of
these limitations are:

• These measures do not reflect our cash expenditures, future requirements

for capital expenditures or contractual commitments;

• These measures do not reflect changes in, or cash requirements for, our


        working capital needs;


                                       45

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

• Adjusted EBITDA and Adjusted EBITDA Margin do not reflect the significant

interest expense, or the cash requirements necessary to service interest

or principal payments, on our debt;

• Adjusted EBITDA and Adjusted EBITDA Margin do not reflect our income tax

expense or the cash requirements to pay our taxes;

• Adjusted Gross Profit, Adjusted Net Income, Adjusted Diluted EPS and

Adjusted EBITDA exclude the expense of depreciation, in the case of

Adjusted Gross Profit and Adjusted EBITDA, and amortization, in each case,

of our assets, and, although these are non-cash expenses, the assets being

depreciated or amortized may have to be replaced in the future;

• Adjusted Net Income, Adjusted Diluted EPS and Adjusted EBITDA exclude the

expense associated with our equity compensation plan, although equity

compensation has been, and will continue to be, an important part of our

compensation strategy;

• Adjusted Gross Profit, Adjusted Net Income, Adjusted Diluted EPS and

Adjusted EBITDA exclude certain business transformation costs, acquisition

costs and other costs, each of which can affect our current and future

cash requirements; and

• Other companies in our industry may calculate Adjusted Gross Profit,


        Adjusted Gross Profit Margin, Adjusted Net Income, Adjusted Diluted EPS,
        Adjusted EBITDA and Adjusted EBITDA Margin differently than we do,
        limiting their usefulness as comparative measures.

Because of these limitations, none of these metrics should be considered indicative of discretionary cash available to us to invest in the growth of our business or as measures of cash that will be available to us to meet our obligations.

measures calculated in accordance with GAAP to these non-GAAP financial measures
for the periods indicated:

Liquidity and Capital Resources

Liquidity Outlook



Our primary cash needs are to fund working capital, capital expenditures, debt
service and any acquisitions we may undertake. As of September 30, 2021, we had
cash and cash equivalents of $250.5 million and total indebtedness of
$467.7 million. CPG International LLC, our direct, wholly owned subsidiary, had
approximately $146.7 million  available under the borrowing base of our
Revolving Credit Facility for future borrowings as of September 30, 2021. CPG
International LLC has the option to increase the commitments under the Revolving
Credit Facility by up to $100.0 million, subject to certain conditions.

We believe we will have adequate liquidity over the next 12 months to operate
our business and to meet our cash requirements as a result of cash flows from
operating activities, available cash balances and availability under our
Revolving Credit Facility after consideration of our debt service and other cash
requirements. In the longer term, our liquidity will depend on many factors,
including our results of operations, our future growth, the timing and extent of
our expenditures to develop new products and improve our manufacturing
capabilities, the expansion of our sales and marketing activities and the extent
to which we make acquisitions. Changes in our operating plans, material changes
in anticipated sales, increased expenses, acquisitions or other events may cause
us to seek additional equity and/or debt financing in future periods.

Holding Company Status



We are a holding company and do not conduct any business operations of our own.
As a result, we are largely dependent upon cash dividends and distributions and
other transfers from our subsidiaries to meet our obligations. The agreements
governing the indebtedness of our subsidiaries impose restrictions on our
subsidiaries' ability to pay dividends or make other distributions to us.

CPG International LLC is party to the Senior Secured Credit Facilities. The
obligations under the Senior Secured Credit Facilities are secured by specified
assets. The obligations under the Senior Secured Credit Facilities are
guaranteed by The AZEK Company Inc. and the wholly owned domestic subsidiaries
of CPG International LLC other than certain immaterial subsidiaries and other
excluded subsidiaries.

The Senior Secured Credit Facilities contain covenants restricting payments of
dividends by CPG International LLC unless certain conditions, as provided in the
Senior Secured Credit Facilities, are met. The covenants under our Senior
Secured Credit Facilities provide for certain exceptions for specific types of
payments. However, other than restricted payments under the specified
exceptions, the covenants under our Term Loan Agreement generally prohibit the
payment of dividends unless the fixed charge coverage ratio of CPG International
LLC, on a pro forma basis, for the four quarters preceding the declaration or
payment of such dividend would be at least 2.00 to 1.00 and such restricted
payments do not exceed an amount based on the sum of $40.0 million plus 50% of
consolidated net income for the period commencing October 1, 2013 to the end of
the most recent fiscal quarter for which internal consolidated financial
statements of CPG International LLC are available at the time of such restricted
payment, plus certain customary addbacks. Based on the general restrictions in
our Term Loan Agreement as of September 30, 2021, CPG International LLC would
have been permitted to declare or pay dividends of up to $168.5 million, plus
any dividends for the specific purposes specified in the Senior Secured Credit
Facilities.

Since the restricted net assets of the Company exceed 25% of our consolidated
net assets, in accordance with Rule 12-04, Schedule 1 of Regulation S-X, refer
to our Consolidated Financial Statements included elsewhere in this Annual
Report for condensed parent company financial statements of the Company.

Cash Sources



We have historically relied on cash flows from operations generated by CPG
International LLC, borrowings under the credit facilities, issuances of notes
and other forms of debt financing and capital contributions to fund our cash
needs.

On September 30, 2013, our subsidiary, CPG International LLC (as
successor-in-interest to CPG Merger Sub LLC, a limited liability company formed
to effect the acquisition of CPG International LLC), Deutsche Bank AG New York
Branch, as administrative agent and collateral agent, or the Revolver
Administrative Agent, and the lenders party thereto entered into the Revolving
Credit Facility. The Revolving Credit Facility provides for maximum aggregate
borrowings of up to $150.0 million, subject to an asset-based borrowing base.
The borrowing base is limited to a specified percentage of eligible accounts
receivable and inventory, less reserves that may be established by the Revolver
Administrative Agent in the exercise of its reasonable credit judgment. As of
September 30, 2021 and 2020, CPG International LLC had no outstanding borrowings
under the Revolving Credit Facility and had $3.3 million and $6.8 million,
respectively, of outstanding letters of credit held against the Revolving Credit
Facility. As of September 30, 2021 and 2020, CPG International LLC had
approximately $146.7 million and $129.4 million, respectively, available under
the borrowing base for future borrowings in addition to cash and cash
equivalents on hand of $250.5 million and $215.0 million, respectively. Because
our borrowing capacity under the Revolving Credit Facility depends, in part, on
inventory,

                                       49

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

accounts receivable and other assets that fluctuate from time to time, the amount available under the borrowing base may not reflect actual borrowing capacity under the Revolving Credit Facility.

Cash Uses



Our principal cash requirements have included working capital, capital
expenditures, payments of principal and interest on our debt, and, if market
conditions warrant, making selected acquisitions. We may elect to use cash from
operations, debt proceeds, equity or a combination thereof to finance future
acquisition opportunities.

Year Ended September 30, 2021, Compared with Year Ended September 30, 2020

Cash Provided by (Used in) Operating Activities



Net cash provided by operating activities was $207.7 million and $98.4 million
for the years ended September 30, 2021 and 2020, respectively. The $109.3
increase in cash provided by operating activities is primarily related to the
increase in net income over the year ended September 30, 2020.

Cash Provided by (Used in) Investing Activities



Net cash used in investing activities was $175.1 million and $113.8 million for
the years ended September 30, 2021 and 2020, respectively. Net cash used in
investing activities for the year ended September 30, 2021 primarily consisted
of purchases of property, plant and equipment to support our expansion of
capacity in our manufacturing facilities, as compared to the year ended
September 30, 2020, which primarily consisted of purchases of property, plant
and equipment in the normal course of business and $18.5 million for the
acquisition of Return Polymers, Inc.

Cash Provided by (Used in) Financing Activities



Net cash provided by financing activities was $2.9 million and $124.5 million
for the years ended September 30, 2021 and 2020, respectively. Net cash provided
by financing activities for the year ended September 30, 2021 consisted of
proceeds of cash received from the exercise of stock options, offset by debt
fees paid to third parties, as compared to the year ended September 30, 2020,
which consisted of proceeds from our IPO, net of related costs, our issuance of
the 2025 Senior Notes and the Revolving Credit Facility, offset by our
redemption of the 2025 Senior Notes and the 2021 Senior Notes, debt payments and
redemptions of capital contributions.

Year Ended September 30, 2020, Compared with Year Ended September 30, 2019

Cash Provided by (Used in) Operating Activities



Net cash provided by operating activities was $98.4 million and $94.9 million
for the years ended September 30, 2020 and 2019, respectively. During the first
half of our fiscal year, we operate programs to prepare for increased purchases
during the building season, and as a result, we typically experience an increase
in cash used in operating activities relative to the second half of our fiscal
year. During the year ended September 30, 2020, our operating cash flow
increased as a result of the increased demand for our Residential products,
partially offset by higher accounts receivable and inventory balances.

Ultralox.

Availability under our Revolving Credit Facility



The Revolving Credit Facility provides for maximum aggregate borrowings of up to
$150.0 million, subject to an asset-based borrowing base. Outstanding revolving
loans under the Revolving Credit Facility will bear interest at a rate which
equals, at our option, either (i) for alternative base rate, or ABR, borrowings,
the highest of (a) the Federal Funds Rate plus 50 basis points, (b) the prime
rate and (c) the LIBOR, as of such date for a deposit in U.S. dollars with a
maturity of one month plus 100 basis points, plus, in each case, a spread of 25
to 75 basis points based on average historical availability, or (ii) for
Eurocurrency borrowings, adjusted LIBOR plus a spread of 125 to 175 basis
points, based on average historical availability. The maturity of the Revolving
Credit Facility is the earlier of March 31, 2026 and the date that is 91 days
prior to the maturity of the Term Loan Agreement or any permitted refinancing
thereof.

A "commitment fee" accrues on any unused portion of the revolving commitments
under the Revolving Credit Facility during the preceding three calendar month
period. If the average daily used percentage is greater than 50%, the commitment
fee equals 25 basis points, and if the average daily used percentage is less
than or equal to 50%, the commitment fee equals 37.5 basis points.

The obligations under the Revolving Credit Facility are secured by a first
priority security interest in certain assets, including substantially all of the
accounts receivable, inventory, deposit accounts, securities accounts and cash
assets of The AZEK Company Inc., CPG International LLC and the subsidiaries of
CPG International LLC that are guarantors under the Revolving Credit Facility,
and the proceeds thereof (subject to certain exceptions), or the Revolver
Priority Collateral, plus a second priority security interest in all of the Term
Loan Priority Collateral (as defined below). The obligations under the Revolving
Credit Facility are guaranteed by The AZEK Company Inc. and the wholly owned
domestic subsidiaries of CPG International LLC other than certain immaterial
subsidiaries and other excluded subsidiaries.

Revolving loans under the Revolving Credit Facility may be voluntarily prepaid
in whole, or in part, in each case without premium or penalty. CPG International
LLC is also required to make mandatory prepayments (i) when aggregate borrowings
exceed commitments or the applicable borrowing base and (ii) during "cash
dominion," which occurs if (a) the availability under the Revolving Credit
Facility is less than the greater of (i) $12.5 million and (ii) 10% of the
lesser of (x) $150.0 million and (y) the borrowing base, for five consecutive
business days or (b) certain events of default have occurred and are continuing.

The Revolving Credit Facility contains affirmative covenants that are customary
for financings of this type, including allowing the Revolver Administrative
Agent to perform periodic field exams and appraisals to evaluate the borrowing
base. The Revolving Credit Facility contains various negative covenants,
including limitations on, subject to certain exceptions, the incurrence of
indebtedness, the incurrence of liens, dispositions, investments, acquisitions,
restricted payments, transactions with affiliates, as well as other negative
covenants customary for financings of this type. The Revolving Credit Facility
also includes a financial maintenance covenant, applicable only when the excess
availability is less than the greater of (i) 10% of the lesser of the aggregate
commitments under the Revolving Credit Facility and the borrowing base, and (ii)
$12.5 million. In such circumstances, we would be required to maintain a minimum
fixed charge coverage ratio (as defined in the Revolving Credit Facility) for
the trailing four quarters equal to at least 1.0 to 1.0; subject to our ability
to make an equity cure (no more than twice in any four quarter period and up to
five times over the life of the facility). As of September 30, 2021 and 2020,
CPG International LLC was in compliance with the financial and nonfinancial
covenants imposed by the Revolving Credit Facility. The Revolving Credit
Facility also includes customary events of default, including the occurrence of
a change of control.

We also have the option to increase the commitments under the Revolving Credit Facility by up to $100.0 million, subject to certain conditions.

Term Loan Agreement



The Term Loan Agreement is a first lien term loan. As of each of September 30,
2021 and 2020, CPG International LLC had $467.7 million outstanding under the
Term Loan Agreement. The Term Loan Agreement will mature on May 5, 2024.

The interest rate applicable to the outstanding principal under the Term Loan
Agreement equals, at our option, either, (i) in the case of ABR borrowings, the
highest of (a) the Federal Funds Rate as of such day plus 50 basis points, (b)
the prime rate and (c) the LIBOR as of such day for a deposit in U.S. dollars
with a maturity of one month plus 100 basis points, provided that in no event
will the alternative base rate be less than 175 basis points, plus, in each
case, the applicable margin of 150 basis points per annum; or (ii) in the case
of Eurocurrency borrowings, the greater of (a) the LIBOR in effect for such
interest period divided by one, minus the statutory reserves applicable to such
Eurocurrency borrowing, if any, and (b) 75 basis points, plus the applicable
margin of 250 basis points per annum. The applicable margin may be reduced by a
further 25 basis points in respect of both Eurocurrency borrowings and ABR
borrowings during any period that CPG International LLC maintains specified
public corporate family ratings.

The obligations under the Term Loan Agreement are secured by a first priority
security interest in the membership interests of CPG International LLC owned by
The AZEK Company Inc., the equity interests of CPG International LLC's domestic
subsidiaries and all remaining assets not constituting Revolver Priority
Collateral (subject to certain exceptions) of The AZEK Company Inc., CPG
International LLC and the subsidiaries of CPG International LLC that are
guarantors under the Term Loan Agreement, or the Term Loan Priority Collateral,
and a second priority security interest in the Revolver Priority Collateral. The
obligations under the Term Loan Agreement are guaranteed by The AZEK Company
Inc. and the wholly owned domestic subsidiaries of CPG International LLC other
than certain immaterial subsidiaries and other excluded subsidiaries.

The Term Loan Agreement may be voluntarily prepaid in whole, or in part, in each
case without premium or penalty (other than the Prepayment Premium, as defined
in the Term Loan Agreement, if applicable), subject to certain customary
conditions. CPG International LLC is also required to make mandatory prepayments
in an amount equal to (i) 100% of the net cash proceeds from casualty events or
the disposition of property or assets, subject to customary reinvestment rights,
(ii) 100% of the net cash proceeds from the incurrence or issuance of
indebtedness (other than permitted indebtedness) by CPG International LLC or any
restricted subsidiary and (iii) 50% of excess cash flow, with such percentage
subject to reduction (to 25% and to 0%) upon achievement of specified leverage
ratios and which prepayment may be declined by the lenders under the Term Loan
Agreement. As of September 30, 2021, and 2020, no excess cash flow payment was
required based on the current leverage ratio. The lenders under the Term Loan
Agreement have the option to decline any prepayments based on excess cash flows.
At the lenders' option the excess cash flow payment made in January 2020 was
$2.2 million with the remaining prepayment declined by the lenders.
Additionally, CPG International LLC is required to pay the outstanding principal
amount of the Term Loan Agreement in quarterly installments of 0.25253% of the
aggregate principal amount under the Term Loan Agreement outstanding, and such
quarterly payments may be reduced as a result of prepayments. Based on the
prepayment of $337.7 million made with net proceeds we received from our IPO,
CPG International LLC has prepaid all of the quarterly principal payments
otherwise due through the maturity of the Term Loan Agreement.

The Term Loan Agreement contains affirmative covenants, negative covenants and
events of default, which are broadly consistent with those in the Revolving
Credit Facility (with certain differences consistent with the differences
between a revolving loan and term loan) and that are customary for facilities of
this type. The Term Loan Agreement does not have any financial maintenance
covenants. As of September 30, 2021 and 2020, CPG International LLC was in
compliance with the covenants imposed by the Term Loan Agreement. The Term Loan
Agreement also includes customary events of default, including the occurrence of
a change of control.

We have the right to arrange for incremental term loans under the Term Loan
Agreement of up to an aggregate principal amount of $150.0 million, plus the
amounts incurred under Incremental Amendment No. 1 thereto, plus any amounts
previously voluntarily prepaid, with additional incremental term loans available
if certain leverage ratios are achieved.

Restrictions on Dividends



The Senior Secured Credit Facilities each restrict payments of dividends unless
certain conditions, as provided in the Revolving Credit Facility or the Term
Loan Agreement, as applicable, are met.

Contingent Commitments



We have contractual commitments for purchases of certain minimum quantities of
raw materials at index-based prices, and non-cancelable capital and operating
leases, outstanding letters of credit and fixed asset purchase commitments. For
a description of our contractual obligations and commitments, see Notes 7
"Debt", 9 "Leases" and 17 "Commitments and Contingencies" to our Consolidated
Financial Statements included elsewhere in this Annual Report.

Other



We are currently in the process of a multi-phase capacity expansion program
including the opening of a new manufacturing facility to be located in Boise,
Idaho. In connection with our capacity expansion program, we have announced our
intention to invest approximately $230 million through 2022 which we expect to
add a total of approximately 85% of incremental decking capacity relative to our
decking capacity at the end of fiscal year 2019, combined with increases in
recycling, railing and exteriors capacity. The first and second phases of our
multi-phase capacity expansion plan were completed during the third quarter of
fiscal year 2021, providing cumulatively approximately 40% more decking
capacity. We subsequently upsized our expansion plans at our Wilmington, Ohio
facility and expect to add an incremental approximately 15% of decking and
recycling capacity in early 2022. The third phase involves the opening of a new
manufacturing facility, which will be located in Boise, Idaho and is expected to
be operational during fiscal 2022 and contribute approximately 30% more decking
capacity.

We also intend to continue to invest in new capacity in the ordinary course as we execute against the long-term material conversion opportunity and market expansion.

Critical Accounting Policies, Estimates and Assumptions



A discussion of our significant accounting policies and significant accounting
estimates and judgments is presented in the Summary of Significant Accounting
Policies in the Notes to our Consolidated Financial Statements included
elsewhere in this Annual Report. Throughout the preparation of the financial
statements, we employ significant judgments in the application of accounting
principles and methods. These judgments are primarily related to the assumptions
used to arrive at various estimates. These significant accounting estimates and
judgments include:

Revenue Recognition

Our Residential segment generates revenue from the sale of our innovative, low-maintenance, sustainable Outdoor Living products, including decking, railing, trim, moulding, pavers products and accessories. Our Commercial segment generates revenue from the sale of sustainable low-maintenance privacy and storage solution products and highly engineered plastic sheet products.



We recognize revenues when control of the promised goods is transferred to our
customers in an amount that reflects the consideration we expect to be entitled
to in exchange for those goods, at a point in time, when shipping occurs. Each
product we transfer to the customer is considered one performance obligation. We
have elected to account for shipping and handling costs as activities to fulfill
the promise to transfer the goods. As a result of this accounting policy
election, we do not consider shipping and handling activities as promised
services to our customers.

Customer contracts are typically fixed price and short-term in nature. The
transaction price is based on the product specifications and is determined at
the time of order. We do not engage in contracts greater than one year, and
therefore do not have any incremental costs capitalized as of September 30, 2021
or September 30, 2020.

We may offer various sales incentive programs throughout the year. We estimate
the amount of sales incentive to allocate to each performance obligation, or
product shipped, using the most-likely-amount method of estimation, based on
sales to the direct customer or sell-through customer. The estimate is updated
each reporting period and any changes are allocated to the performance
obligations on the same basis as at inception. Changes in estimate allocated to
a previously satisfied performance obligation are recognized as part of net
revenue in the period in which the change occurs under the cumulative catch-up
method. In addition to sales incentive programs, we may offer a payment
discount, if payments are received within 30 days. We estimate the payment
discount that we determine will be taken by the customer based on prior history
and using the most-likely-amount method of estimation. We believe the
most-likely-amount method best predicts the amount of consideration to which we
will be entitled. The payment discounts are also reflected as part of net
revenue. The total amount of incentives was $92.5 million, $63.1 million and
$50.8 million for the years ended September 30, 2021, 2020 and 2019,
respectively.

Customer program costs and incentives, such as rebates are a common practice in
our business. We incur customer program costs to promote sales of products and
to maintain competitive pricing. Customer program costs and incentives include
annual programs related to volume growth as well as certain product-specific
incentives. The program costs are accounted for at the time the revenue is
recognized in net sales. Management's estimates are based on historical and
projected experience for each type of program or customer and in consideration
of product specific incentives. Management periodically reviews accruals for
these rebates and allowances, and adjusts accruals when circumstances indicate
(typically as a result of a change in volume expectations).

Goodwill



We evaluate goodwill for impairment in the fourth quarter at the reporting unit
level annually, or more frequently if an event occurs or circumstances change in
the interim that would more likely than not reduce the fair value of the asset
below the carrying amount. Goodwill is considered to be impaired when the net
book value of the reporting unit exceeds its estimated fair value. Our
evaluation may begin with a qualitative assessment of the factors that could
impact the significant inputs used to estimate fair value to determine if it is
more likely than not that the fair value of the reporting unit is less than its
carrying amount or we may elect to bypass the qualitative assessment and proceed
to a quantitative assessment to determine if goodwill is impaired. In
quantitative impairment tests, we first compare the fair value of the reporting
unit to the carrying value. If the carrying value of a reporting unit exceeds
its fair value, the goodwill of that reporting unit is impaired and an
impairment loss is recognized for the excess up to the amount of goodwill
allocated to the reporting unit.

We measure fair value of the reporting units to which goodwill is allocated
using an income based approach, a generally accepted valuation methodology,
using relevant data available through and as of the impairment testing date.
Under the income approach, fair value is determined using a discounted cash flow
method, projecting future cash flows of each reporting unit, as well as a
terminal value, and discounting such cash flows at a rate of return that
reflects the relative risk of the cash flows. The key

                                       54

--------------------------------------------------------------------------------
assumptions and factors used in this approach include, but are not limited to,
revenue growth rates and profit margins based on internal forecasts, a weighted
average cost of capital used to discount future cash flows, and a review with
comparable market multiples for the industry segment as well as our historical
operating trends. Any impairment is increased to encompass the income tax
effects of any tax deductible goodwill on the carrying amount of the reporting
unit, so that the after-tax impairment loss is equivalent to the amount by which
the carrying value of the reporting unit exceeds its fair value.

No impairments were recorded during the year ended September 30, 2021 as the
estimated fair value substantially exceeded the carrying value for all reporting
units.

Product Warranties

We provide product assurance warranties against certain defects to our customers
based on standard terms and conditions for periods beginning as of the sale date
and lasting from five years to a lifetime, depending on the product and subject
to various limitations. We provide for the estimated cost of warranties by
product line at the time revenue is recognized based on management's judgment,
considering such factors as cost per claim, historical experience, anticipated
rates of claims, and other available information, including our stated warranty
policies and procedures. Management reviews and adjusts these estimates, if
necessary, based on the differences between actual experience and historical
estimates. Because warranty issues may surface later in the product life cycle,
management continues to review these estimates on a regular basis and considers
adjustments to these estimates based on actual experience compared to historical
estimates. Estimating the required warranty reserves requires a high level of
judgment, especially as many of our products are at a relatively early stage in
their product life cycles. The warranty obligation is reflected in other current
and other non-current liabilities in the consolidated balance sheets.

Equity Based Compensation

Prior to our IPO



To assist us in attracting, retaining, incentivizing and motivating employees,
certain employees were granted limited partnership interests in our former
indirect parent entity, which we refer to as the Partnership, that generally
were intended to constitute "profits interests," or the Profits Interests. The
Profits Interests were subject to specified hurdle amounts, which functioned
like option exercise prices because the Profits Interests did not participate in
distributions by the Partnership until distributions to equity holders had
exceeded the relevant hurdle amounts. In general, awards of Profits Interests
were 50% time vested and 50% performance vested.

Prior to completion of our IPO, interests in the Partnership, including the
Profits Interests, were not listed on any established exchange. In determining
the fair value of the Profits Interests, we took into account the methodologies
and approaches described in the American Institute of Certified Public
Accountants Accounting and Valuation Guide, Valuation of Privately-Held Company
Equity Securities Issued as Compensation. The sole material asset of the
Partnership was indirect ownership of our company. Accordingly, the fair value
of the Profits Interests was derived by reference to the value of our company,
which we estimated using a combination of the income approach and the market
approach. Under the income approach, we estimated the fair value of our company
based on the present value of our future estimated cash flows and the estimated
residual value of our company beyond the forecast period. These future values
were discounted to their present values at a discount rate deemed appropriate to
reflect the risks inherent in achieving these estimated cash flows. Significant
estimates and judgments involved in the income approach include our estimated
future cash flows, the perpetuity growth rate assumed in estimating the residual
value of our cash flows and the discount rate used to discount our cash flows to
present value. For the market approach, we utilized the comparable company
method by analyzing a group of companies that were considered to be comparable
to us in terms of product offerings, revenue, margins and/or growth. We then
used these companies to develop relevant market multiples, which were applied to
our corresponding financial metrics to estimate our equity value. Significant
estimates and judgments used in the comparable company method included the
selection of comparable companies and the selection of appropriate market
multiples. Application of these approaches involves the use of estimates,
judgment and assumptions that are highly subjective. Following our IPO, it is
not necessary to apply these valuation approaches as shares of our Class A
common stock are traded in the public market.

In order to determine the value of the Profits Interests, the estimated equity
value of the Partnership was allocated among the various interests in the
Partnership, including the Profits Interests, using the option pricing method,
which treated the various interests in the Partnership as call options with
exercise prices determined based on their respective rights to participate in
distributions by the Partnership. The values attributable to these implicit call
options were determined using the Black-Scholes option pricing model. The
Black-Scholes option pricing model requires the use of highly subjective
assumptions, including volatility and the expected term of the call options. As
equity interests in the Partnership were not publicly traded, expected
volatility was derived based on the volatilities of a peer group of publicly
traded companies that were deemed to be similar to us. The expected term of the
options was based on the anticipated time to liquidity. Other assumptions
include the risk-free rate of interest and dividend yield. The risk-free rate of
interest was based on yields for U.S. Treasury securities with remaining
maturities corresponding to the estimated term of the options. Dividends were
assumed to be zero, consistent with historical experience. After the equity
value was determined and

                                       55

--------------------------------------------------------------------------------
allocated to the various classes of interests in the Partnership, including the
Profits Interests, a discount for lack of marketability, or DLOM, was applied to
derive the fair value of the Profits Interests. A DLOM is meant to account for
the lack of marketability of a security that is not publicly traded.

The cost of time-vested Profits Interests was recognized as an expense generally
on a straight-line basis over the employee's requisite service period, which
generally coincided with the vesting of the award. For performance vested
Profits Interests, expense was recognized if and when the achievement of the
applicable performance criteria became probable. Performance vested Profits
Interests only vested upon receipt by the Sponsors of specified proceeds (in the
form of cash and marketable securities) or, in the event of a Change of Control
(as defined in the Amended and Restated Agreement of Limited Partnership of the
Partnership, dated as of September 30, 2013), upon the Sponsors achieving a
specified rate of return. Through September 30, 2019 and immediately prior to
the IPO, no compensation expense had been recognized with respect to the
performance vested Profits Interests because the achievement of the performance
criteria had not become probable.

Subsequent to our IPO



We determine the expense for all employee stock-based compensation awards by
estimating their fair value and recognizing such value as an expense, on a
straight-line, ratable or cliff basis, depending on the award, in our
consolidated financial statements over the requisite service period in which
employees earn the awards. We estimate the fair value of performance-based
awards granted to employees using the Monte Carlo pricing model and for
service-based awards granted to employees using the Black Scholes pricing model.
The fair value of performance-based awards that are expected to vest is
recognized as compensation expense on a straight-line basis over the requisite
service period. The fair value of service-based awards that are expected to vest
is recognized as compensation expense on either (1) a straight-line basis, (2) a
ratable vesting basis or (3) a cliff vesting basis. We account for forfeitures
as they occur.

To determine the fair value of a stock-based award using the Monte Carlo and
Black Scholes models, we make assumptions regarding the risk-free interest rate,
expected future volatility, expected dividend yield and performance period. The
risk-free rate is based on the U.S. treasury yield curve in effect at the time
of grant. We estimate the expected volatility of the share price by reviewing
the estimated volatility levels of our Class A common stock in conjunction with
the historical volatility levels of public companies that operate in similar
industries or are similar in terms of stage of development or size and then
projecting this information toward its future expected volatility. We exercise
judgment in selecting these companies, as well as in evaluating the available
historical and implied volatility for these companies. Dividend yield is
determined based on our future plans to pay dividends. We calculate the
performance period based on the specific market condition to be achieved and
derived from estimates of future performance. We calculate the expected term in
years for each stock option using a simplified method based on the average of
each option's vesting term and original contractual term. The simplified method
is used due to the lack of sufficient historical data available to provide a
reasonable basis upon which to estimate the expected term of each stock option.

Stock-Based Compensation Expense



We recognized $22.7 million, $120.5 million and $3.3 million in stock-based
compensation expense during the years ended September 30, 2021, 2020 and 2019,
respectively. The stock-based compensation expense recognized in fiscal year
2020 is primarily a result of the vesting of performance-based equity awards due
to the Sponsors receiving sufficient proceeds from our secondary offering
completed in September 2020. As of September 30, 2021, the Company had not yet
recognized compensation cost on unvested stock-based awards of $24.5 million,
with a weighted average remaining recognition period of 2.4 years.

Income Taxes



In determining our current income tax provision, we assessed temporary
differences resulting from differing treatments of items for tax and accounting
purposes. These differences resulted in deferred tax assets and liabilities
which are recorded in our consolidated balance sheets. When we maintain deferred
tax assets, we must assess the likelihood that these assets will be recovered
through adjustments to future taxable income. To the extent we believe, based on
available evidence, it is more likely than not that all or some portion of the
asset will not be realized, we establish a valuation allowance. We record an
allowance reducing the asset to a value we believe is more likely than not to be
realized based on our expectation of future taxable income. We believe the
accounting estimate related to the valuation allowance is a critical accounting
estimate because it is highly susceptible to change from period to period as it
requires management to make assumptions about our future income over the lives
of the deferred tax assets, and the impact of increasing or decreasing the
valuation allowance is potentially material to our results of operations.

Forecasting future income requires us to use a significant amount of judgment.
In estimating future income, we use our internal operating budgets and
long-range planning projections. We developed our budgets and long-range
projections based on recent results, trends, economic and industry forecasts
influencing our segments' performance, our backlog, planned timing of new
product launches,

                                       56

--------------------------------------------------------------------------------
and customer sales projections. Significant changes in the expected realization
of net deferred tax assets would require that we adjust the valuation allowance,
resulting in a change to net income.

We record liabilities for uncertain income tax positions based on a two-step
process. The first step is recognition, where we evaluate whether an individual
tax position has a likelihood of greater than 50% of being sustained upon
examination based on the technical merits of the position, including resolution
of any related appeals or litigation processes. For tax positions that are
currently estimated to have a less than 50% likelihood of being sustained, no
tax benefit is recorded. For tax positions that have met the recognition
threshold in the first step, we perform the second step of measuring the benefit
(expense) to be recorded. The actual benefits (expense) ultimately realized may
differ from our estimates. In future periods, changes in facts, circumstances,
and new information may require us to change the recognition and measurement
estimates with regard to individual tax positions. Changes in recognition and
measurement estimates are recorded in the consolidated statement of income and
consolidated balance sheet in the period in which such changes occur. As of
September 30, 2021 and 2020, we had liabilities for unrecognized tax benefits
pertaining to uncertain tax positions totaling $1.0 million and $1.0 million,
respectively.

Recently Adopted Accounting Pronouncements

Under the Jumpstart Our Business Startups Act, we qualified as an emerging growth company, or an EGC, and as such, have elected not to opt out of the extended transition period for complying with new or revised accounting pronouncements. During the extended transition period, we were not subject to new or revised accounting standards applicable to public companies.



Based on our public float calculation at March 31, 2021, we are deemed a Large
Accelerated Filer under the U.S. Securities and Exchange Commission guidelines
and ceased to qualify as an EGC effective September 30, 2021. The loss of EGC
status resulted in losing the reporting exemptions noted above, and in
particular required our independent registered public accounting firm to provide
an attestation report on the effectiveness of our internal control over
financial reporting as of and for the year ended September 30, 2021 under
Section 404(b) of the Sarbanes-Oxley Act.

On October 1, 2018, we early adopted ASU No. 2014-09, Revenue from Contracts
with Customers, which outlines a single comprehensive model for entities to use
in accounting for revenue arising from contracts with customers. The update will
supersede most current revenue recognition guidance. Under the new standard,
entities are required to identify the contract with a customer; identify the
separate performance obligations in the contract; determine the transaction
price; allocate the transaction price to the separate performance obligations in
the contract; and recognize the appropriate amount of revenue when (or as) the
entity satisfies each performance obligation. The adoption of this standard did
not have a material impact on our Consolidated Financial Statements.

On October 1, 2019, we adopted ASU No. 2016-16, Income Taxes (Topic 740):
Intra-Entity Transfer of Assets Other Than Inventory. The standard amends
several aspects of the tax accounting and recognition timing for intra-company
transfers. We adopted the standard using a modified retrospective approach, with
an adjustment to the beginning retained earnings of approximately $1.3 million,
due to the cumulative impact of adopting the standard. The adoption of this
standard did not have a material impact on our Consolidated Financial
Statements.

On October 1, 2020, we adopted ASU No. 2018-13, Disclosure Framework-Changes to
the Disclosure Requirements for Fair Value Measurement, which amends Topic 820,
Fair Value Measurement. This standard modifies the disclosure requirements for
fair value measurements by removing, modifying, or adding certain disclosures.
The adoption of this standard did not have a material impact on our Consolidated
Financial Statements.

On October 1, 2020, we adopted ASC 842 (Leases) using the transition method
introduced by ASU 2018-11, which does not require revisions to comparative
periods. Adoption of the new standard resulted in the recording of lease assets
and lease liabilities of approximately $15.2 million and $18.7 million,
respectively, as of October 1, 2020. The difference between the lease assets and
lease liabilities primarily relates to accrued rent and unamortized lease
incentives recorded in accordance with the previous leasing guidance. As of the
adoption date, accumulated deficit within shareholder's equity on our
consolidated balance sheet decreased by $2.1 million, primarily related to the
derecognition of build-to-suit leasing arrangements. The new standard did not
materially impact our consolidated statements of income or cash flows.

On October 1, 2020, we adopted ASU No. 2016-13, Financial Instruments-Credit
Losses (Topic 326), and the subsequent amendments The standard sets forth an
expected credit loss model which requires the measurement of expected credit
losses for financial instruments based on historical experience, current
conditions and reasonable and supportable forecasts. This replaces the existing
incurred loss model and is applicable to the measurement of credit losses on
financial assets measured at amortized cost, and certain off-balance sheet
credit exposures. The adoption of this standard did not have a material impact
on our Consolidated Financial Statements.

                                       57

--------------------------------------------------------------------------------
On October 1, 2020, we adopted ASU No. 2018-15, Intangibles-Goodwill and
Other-Internal-Use Software (Subtopic 350-40): The standard aligns the
requirements for capitalizing implementation costs incurred in a hosting
arrangement that is a service contract with the requirements for capitalizing
implementation costs incurred to develop or obtain internal-use software. The
adoption of the standard did not have a material impact on our Consolidated
Financial Statements.

On October 1, 2020, we adopted ASU No. 2020-04, Reference Rate Reform (Topic
848), The standard provides optional expedients and exceptions for applying
generally accepted accounting principles to contract modifications and hedging
relationships, subject to meeting certain criteria, that reference LIBOR or
another reference rate expected to be discontinued. The adoption of the standard
did not have a material impact on our Consolidated Financial Statements.

Recently Issued Accounting Pronouncements



In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic
740)-Simplifying the Accounting for Income Taxes. This standard simplifies the
accounting for income taxes by removing certain exceptions to general principles
in Topic 740 and clarifying and amending existing guidance. For public entities,
the amendments in this ASU are effective for fiscal years, and interim periods
within those fiscal years, beginning after December 15, 2020. For all other
entities, the amendments are effective for fiscal years beginning after December
15, 2021, and interim periods within fiscal years beginning after December 15,
2022. Early adoption of the amendments is permitted, including adoption in any
interim period for (1) public business entities for periods for which financial
statements have not yet been issued and (2) all other entities for periods for
which financial statements have not yet been made available for issuance. An
entity that elects to early adopt the amendments in an interim period should
reflect any adjustments as of the beginning of the annual period that includes
that interim period. Additionally, an entity that elects early adoption must
adopt all the amendments in the same period. The amendments are applied on a
prospective or retrospective basis, depending upon the amendment adopted within
this ASU. The amendments in this ASU are effective for us for annual periods
beginning after December 15, 2020 and interim periods within annual periods
beginning after December 15, 2021. We are currently evaluating the impact this
adoption will have on our Consolidated Financial Statements.
