Key Trends Affecting our Business

We have identified the following material trends affecting our business:

• The COVID-19 pandemic adversely affected our business and operations


          during the year ended December 31, 2020. During the first quarter of
          2020, our China manufacturing facilities were adversely impacted by the
          COVID-19 pandemic in the form of reduced production levels and COVID-19

related costs associated with the health and safety of our associates

and non-productive labor. During the second quarter of 2020, all of our

manufacturing facilities with the exception of our China manufacturing

facilities and our Rhode Island manufacturing facility were required to


          temporarily suspend production or operate at reduced production levels
          due primarily to certain applicable government-mandated stay at home
          orders in response to the COVID-19 pandemic, demands from certain of our

labor unions to suspend or reduce production and general safety concerns


          of our associates. By the end of the second quarter of 2020, most of our
          manufacturing facilities had returned to operating at or near normal
          production levels. Although all of our manufacturing facilities
          currently are operating at or near normal production levels, we may be
          required to reinstate temporary production suspensions or volume

reductions at our manufacturing facilities or at our other locations to


          the extent there is a resurgence of COVID-19 cases in the regions where
          we operate or there is an outbreak of positive COVID-19 cases in any of
          our facilities.

• Our business seeks to capitalize on two major global trends: (i)

increasing worldwide demand for renewable energy; and (ii) increasing


          worldwide demand for electric vehicles.


     •    The wind power generation industry has grown rapidly and expanded

worldwide over the last five years to meet global demand for electricity

and the expanded use of renewable energy. Our sales of wind blades to


          our wind turbine customers have grown rapidly over the last several
          years in response to these trends. In 2020, our net sales grew to $1.67
          billion compared to net sales of $1.44 billion in 2019.


                                       34

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

• We believe the long term global demand for wind energy will continue to

be strong and potentially accelerate in the coming years due to a

multitude of factors, including: increased cost competitiveness of wind

energy compared to fossil fuel generated electricity; increased demand

from corporations and utility providers for renewable energy; recent


          international policy initiatives designed to promote the growth of
          renewable energy; and the Biden administration's proposed plans to

promote renewable energy growth in the United States. However, many of

the recently announced domestic and international policy initiatives to


          expand renewable energy have yet to be implemented into concrete
          legislation and regulations. As such, we expect our revenue in 2021 to
          continue to grow but at a rate lower than our revenue growth rate in

2020 due primarily to lower expected demand for wind blades manufactured

in our China manufacturing facilities, but partially offset by stronger

expected demand for wind blades manufactured in our Mexico, Turkey and

India manufacturing facilities. We expect to produce slightly less wind

blades sets in 2021 compared to 2020, but we expect that the average

sales price per set in 2021 will be higher than in 2020 because we plan

to produce larger wind blades in 2021.

• During the last several years, many wind turbine OEMs have increased the

outsourced production of wind blades and other key components to

specialized manufacturers to meet the increasing global demand for wind

energy in a cost-effective manner in new and growing markets. That

shift, together with the overall expansion of the wind power generation


          industry, has increased our addressable market. Given our growth in
          production, we have hired several thousand new employees globally in the
          past two years. In addition, we have expanded our wind turbine OEM

customer base from one to five OEM customers since 2012, capitalizing on


          the growth and expansion of the wind energy generation industry
          generally as well as the specific trend of most wind turbine OEMs
          increasing the outsourcing of the manufacturing of wind blades for
          growth and diversification.

• Changing customer demands, including shifts to bigger wind turbines with

larger wind blades, have driven some of our customers to require us to

transition to new wind blade models one or two times during the term of

a long-term supply agreement. Although we generally receive transition

payments to compensate us for certain costs incurred during these

transitions, these payments generally do not fully cover the transition

costs and lost margin. In 2020, we postponed several wind blade model

transitions due to the COVID-19 pandemic and also had a significant

number of lines starting up in our new manufacturing facility in

Chennai, India, which had an adverse impact on our results of operations

and profitability in 2020. As such, we expect to have a larger number of

lines in transition during 2021, which will have an adverse impact on

our results of operations for 2021. We expect these line transitions to

provide a foundation for longer term revenue growth and profitability as

these lines ramp up to full production levels.

• We expect our new manufacturing facilities to generally generate


          operating losses in their first 12 to 18 months of operations due to
          production and overhead expenses as they initially operate far below

capacity during the pre-production and production ramp up periods. As a

result, this generally has a negative impact on our results of

operations during these ramp-up periods. In addition, construction of


          new facilities and expansion of existing facilities, including the
          fabrication of precision molding and assembly systems to outfit those
          facilities, is complex and involves inherent risks.


                                       35

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

• The long-term supply agreements we sign with our customers provide us

with significant visibility of future production demands due in part to

the annual minimum purchase commitments of our customers contained in

those agreements. These annual minimum purchase commitments generally

require our customers to purchase a negotiated percentage of the

manufacturing capacity that we have agreed to dedicate to them.

Generally, this percentage begins at 100% of the manufacturing capacity

for the first few years of the supply agreement, and the percentage


          declines over time in subsequent years according to the terms of the
          agreement, but generally remains above 50%. It is our experience that

our customers will generally order wind blades from us in a volume that

exceeds (sometimes substantially) the annual minimum purchase

commitments contained in our supply agreements, particularly in the

later years of a supply agreement when the annual minimum purchase

commitment percentage declines. As of February 24, 2021, our long-term

wind and transportation supply agreements provide for minimum aggregate

volume commitments from our customers of approximately $2.8 billion and


          encourage our customers to purchase additional volume up to, in the
          aggregate, a total contract value of approximately $4.6 billion through
          the end of 2024. As noted elsewhere in this Annual Report on Form 10-K,

some of our long-term supply agreements are subject to early termination


          by our customers if our customers pay an early termination fee. We
          caution investors that the annual minimum purchase commitments in our

long-term supply agreements can understate the forecasted net sales that


          we are likely to generate in a given period or periods if all of our
          long-term supply agreements remain in place and pricing remains
          materially unchanged, and they could potentially overstate the

forecasted net sales that we are likely to generate in a given period or

periods if one or more of our agreements were to be terminated by our

customers for any reason, or our plants are underutilized due to market


          conditions. See "Business-Wind Blade Long-Term Supply Agreements"
          included in Part 1, Item 1A of this Annual Report on Form 10-K for
          additional information.


     •    As the global vehicle electrification trend continues, reducing the

weight of these vehicles is critical to expanding range and/or providing

more room for additional batteries or reducing the number of batteries.

We believe there is an increasing demand for composites products for

electric vehicles. As part of our diversification strategy, we have made

significant investments to expand our transportation business during the

last several years. In 2018 through 2020, we experienced significant

losses relating to our transportation business and experienced

operational challenges as we are expanding this business. Specifically,

we experienced extended startup delays and challenges with respect to

our Newton, Iowa transportation facility, which had an adverse impact on

our results of operations in 2019 and 2020. We ceased manufacturing


          composite bus bodies from our Newton, Iowa manufacturing facility in the
          first quarter of 2020 and consolidated these operations into our Warren,
          Rhode Island manufacturing facility. From 2018 to 2020, we invested

approximately $50 million in our transportation business. We expect our

transportation business will continue to operate at a loss in 2021 and

expect to invest between approximately $15 million and $20 million in

our transportation business in 2021.

COMPONENTS OF RESULTS OF OPERATIONS

Net Sales



We recognize revenue from manufacturing services over time as our customers
control the product as it is produced, and we may not use or sell the product to
fulfill other customers' contracts. Net sales include amounts billed to our
customers for our products, including wind blades, precision molding and
assembly systems and other products and services, as well as the progress
towards the completion of the performance obligation for products in progress,
which is determined on a ratio of direct costs incurred to date in fulfillment
of the contract to the total estimated direct costs required to complete the
performance obligation.

Cost of Goods Sold

Cost of goods sold includes the costs we incur at our production facilities to
make products saleable on both products invoiced during the period as well as
products in progress towards the completion of each performance obligation. Cost
of goods sold includes such items as raw materials, direct and indirect labor
and facilities costs, including purchasing and receiving costs, plant
management, inspection costs, production process improvement activities, product
engineering and internal transfer costs. In addition, all depreciation
associated with assets used in the production of our products is also included
in cost of goods sold. Direct labor costs consist of salaries, benefits and
other personnel related costs for employees engaged in the manufacturing of our
products and services.

                                       36

--------------------------------------------------------------------------------
Startup and transition costs are primarily unallocated fixed overhead costs and
underutilized direct labor costs incurred during the period production
facilities are transitioning wind blade models and ramping up manufacturing. All
direct labor costs are included in the measure of progress towards completion of
the relevant performance obligation when determining revenue to be recognized
during the period. The cost of sales for the initial wind blades from a new
model manufacturing line is generally higher than when the line is operating at
optimal production volume levels due to inefficiencies during ramp-up related to
labor hours per blade, cycle times per blade and raw material usage.
Additionally, these costs as a percentage of net sales are generally higher
during the period in which a facility is ramping up to full production capacity
due to underutilization of the facility. Manufacturing overhead at each of our
facilities includes virtually all indirect costs (including share-based
compensation costs) incurred at the plants, including engineering, finance,
information technology, human resources and plant management.

General and Administrative Expenses



General and administrative expenses primarily relate to the unallocated portion
of costs incurred at our corporate headquarters and our research facilities and
include salaries, benefits and other personnel related costs for employees
engaged in research and development, engineering, finance, internal audit,
information technology, human resources, business development, global
operational excellence, global supply chain, in-house legal and executive
management. Other costs include outside legal and accounting fees, risk
management (insurance), share-based compensation and certain other
administrative and global resources costs.

The unallocated research and development expenses incurred at our Warren, Rhode
Island location as well as at our Kolding, Denmark advanced engineering center
and our Berlin, Germany engineering center are also included in general and
administrative expenses. For the years ended December 31, 2020, 2019 and 2018,
total research and development expenses totaled $1.0 million, $1.0 million and
$0.8 million, respectively.

Loss on Sale of Assets and Asset Impairments



Loss on sale of assets represents the losses on the sale of certain receivables,
on a non-recourse basis under supply chain financing arrangements with our
customers, to financial institutions and losses on the sale of other assets at
our corporate and manufacturing facilities. Asset impairments represent the
losses on the impairment of our assets at our corporate and manufacturing
facilities.

Restructuring Charges



Restructuring charges primarily consist of employee severance, one-time
termination benefits and ongoing benefits related to the reduction of our
workforce and other costs associated with exit activities, which may include
costs related to leased facilities to be abandoned and facility and employee
relocation costs.

Other Income (Expense)

Other income (expense) consists of interest expense on our debt borrowings and
the amortization of deferred financing costs on such borrowings, foreign
currency income and losses, interest income, losses on extinguishment of debt
and miscellaneous income and expense.

Income Taxes



Income taxes consists of federal, state, provincial, local and foreign taxes
based on income in jurisdictions in which we operate, including in the U.S.,
China, Mexico, Turkey and India. The income tax rate, tax provisions, deferred
tax assets and liabilities vary according to the jurisdiction in which the
income or loss arises. Tax laws are complex and subject to different
interpretations by management and the respective governmental taxing authorities
and require us to exercise judgment in determining our income tax provision, our
deferred tax assets and liabilities and the valuation allowance recorded against
our net deferred tax assets.

                                       37

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

KEY METRICS USED BY MANAGEMENT TO MEASURE PERFORMANCE



In addition to measures of financial performance presented in our consolidated
financial statements in accordance with GAAP, we use certain other financial
measures and operating metrics to analyze our performance. These "non-GAAP"
financial measures consist of EBITDA, adjusted EBITDA, free cash flow and net
cash (debt), which help us evaluate growth trends, establish budgets, assess
operational efficiencies, oversee our overall liquidity, and evaluate our
overall financial performance. The key operating metrics consist of wind blade
sets produced, estimated megawatts of energy capacity to be generated by wind
blade sets produced, utilization, dedicated manufacturing lines, and
manufacturing lines installed, which help us evaluate our operational
performance. We believe that these measures are useful to investors in
evaluating our performance.

                             Key Financial Measures



The key financial measures as of and for the years ended December 31 are as
follow:

(1) See below for more information and a reconciliation of EBITDA, adjusted

EBITDA, free cash flow and net debt to net income (loss), net income (loss),

net cash provided by (used in) operating activities and total debt, net of

debt issuance costs, respectively, the most directly comparable financial

measures calculated and presented in accordance with GAAP.

EBITDA and adjusted EBITDA



We define EBITDA, a non-GAAP financial measure, as net income or loss plus
interest expense (including losses on extinguishment of debt and net of interest
income), income taxes and depreciation and amortization. We define adjusted
EBITDA as EBITDA plus any share-based compensation expense, plus or minus any
foreign currency losses or income, plus or minus any losses or gains from the
sale of assets and asset impairments, plus any restructuring charges. Adjusted
EBITDA is the primary metric used by our management and our board of directors
to establish budgets and operational goals for managing our business and
evaluating our performance. In addition, our credit agreement (the Credit
Agreement) that we entered into in April 2018 contains minimum EBITDA (as
defined in the Credit Agreement) covenants with which we must comply. We monitor
adjusted EBITDA as a supplement to our GAAP measures, and believe it is useful
to present to investors, because we believe that it facilitates evaluation of
our period-to-period operating performance by eliminating items that are not
operational in nature, allowing comparison of our recurring core business
operating results over multiple periods unaffected by differences in capital
structure, capital investment cycles and fixed asset base. In addition, we
believe adjusted EBITDA and similar measures are widely used by investors,
securities analysts, ratings agencies, and other parties in evaluating companies
in our industry as a measure of financial performance and debt-service
capabilities.

Our use of adjusted EBITDA has limitations as an analytical tool and you should
not consider it in isolation or as a substitute for analysis of our results as
reported under GAAP. Some of these limitations are:

• adjusted EBITDA does not reflect changes in, or cash requirements for,


          our working capital needs;


     •    adjusted EBITDA does not reflect our cash expenditures for capital
          equipment or other contractual commitments;


                                       38

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


     •    adjusted EBITDA does not reflect the interest expense or the cash
          requirements necessary to service interest or principal payments on our
          indebtedness;

• adjusted EBITDA does not reflect losses on extinguishment of debt

relating to prepayment penalties, termination fees and the write off of

any remaining debt discount and debt issuance costs upon the repayment

or refinancing of our debt;

• adjusted EBITDA does not reflect tax payments that may represent a

reduction in cash available to us;

• although depreciation and amortization are non-cash charges, the assets

being depreciated and amortized may have to be replaced in the future,

and adjusted EBITDA does not reflect capital expenditure requirements

relating to the future need to augment or replace those assets;

• adjusted EBITDA does not reflect share-based compensation expense on

equity-based incentive awards to our officers, employees, directors and

consultants;

• adjusted EBITDA does not reflect the foreign currency income or losses

in our operations;

• adjusted EBITDA does not reflect the gains or losses on the sale of


          assets and asset impairments;


  • adjusted EBITDA does not reflect restructuring charges; and

• other companies, including companies in our industry, may calculate

EBITDA and adjusted EBITDA differently, which reduces their usefulness

as comparative measures.

In evaluating EBITDA and adjusted EBITDA, you should be aware that in the future, we will incur expenses similar to the adjustments noted herein. Our presentations of EBITDA and adjusted EBITDA should not be construed as suggesting that our future results will be unaffected by these expenses or any unusual or non-recurring items. When evaluating our performance, you should consider EBITDA and adjusted EBITDA alongside other financial performance measures, including our net income (loss) and other GAAP measures.

Free cash flow



We define free cash flow as net cash provided by (used in) operating activities
less capital expenditures. We believe free cash flow is a useful measure for
investors because it portrays our ability to generate cash from our business for
purposes such as repaying maturing debt and funding business acquisitions.

Net cash (debt)



We define net cash (debt) as total unrestricted cash and cash equivalents less
the total principal amount of debt outstanding. The total principal amount of
debt outstanding is comprised of the long-term debt and current maturities of
long-term debt as presented in our consolidated balance sheets adding back any
debt issuance costs. We believe that the presentation of net cash (debt)
provides useful information to investors because our management reviews net cash
(debt) as part of our oversight of overall liquidity, financial flexibility and
leverage. Net cash (debt) is important when we consider opening new
manufacturing facilities and expanding existing manufacturing facilities, as
well as for capital expenditure requirements.

The following table reconciles our non-GAAP key financial measures to the most directly comparable GAAP measures:

The key operating metrics as of and for the year ended December 31 are as
follows:



                                  2020        2019        2018
Sets                               3,544       3,189       2,423
Estimated megawatts               12,080       9,598       6,560
Utilization                           81 %        79 %        71 %
Dedicated manufacturing lines         53          52          55
Manufacturing lines installed         55          48          43



(1) See below for more information on each of our key operating metrics.




Sets represents the number of wind blade sets, consisting of three wind blades
each, which we produced worldwide during the period. We monitor sets and believe
that presenting sets to investors is helpful because we believe that it is the
most direct measurement of our manufacturing output during the period. Sets
primarily impact net sales.

Estimated megawatts are the energy capacity to be generated by wind blade sets
produced during the period. Our estimate is based solely on name-plate capacity
of the wind turbine on which the wind blades we manufacture

                                       40

--------------------------------------------------------------------------------
are expected to be installed. We monitor estimated megawatts and believe that
presenting estimated megawatts to investors is helpful because we believe that
it is a commonly followed measurement of energy capacity across our industry and
provides an indication of our share of the overall wind blade market.

Utilization represents the percentage of the number of wind blades invoiced
during the period compared to the total potential wind blade capacity of the
manufacturing lines installed during the period. We monitor utilization because
we believe it helps investors to better understand how close we are to operating
at maximum production capacity.

Dedicated manufacturing lines are the number of wind blade manufacturing lines
that we have dedicated to our customers pursuant to our long-term supply
agreements at the end of the period. We monitor dedicated manufacturing lines
and believe that presenting this metric to investors is helpful because we
believe that the number of dedicated manufacturing lines is the best indicator
of demand for the wind blades we manufacture for customers under our long-term
supply agreements in any given period. Lines become dedicated upon the execution
of a long-term supply agreement; this means that lines are typically dedicated
before they are installed.

Manufacturing lines installed represents the number of wind blade manufacturing
lines installed and either in operation, startup or transition during the
period. We believe that total manufacturing lines installed provides an
understanding of the number of manufacturing lines installed and either in
operation, startup or transition. From time to time, we have manufacturing lines
installed that are not dedicated to our customers pursuant to a long-term supply
agreement.

Net sales

Consolidated discussion



The following table summarizes our net sales by product/service for the years
ended December 31:



                                                                 Change
                             2020            2019             $            %
                                       (in thousands)
Wind blade sales          $ 1,580,055     $ 1,328,717     $ 251,338        18.9 %
Precision molding and
 assembly systems sales        28,073          48,680       (20,607 )     -42.3 %
Transportation sales           36,196          28,870         7,326        25.4 %
Other sales                    25,813          30,233        (4,420 )     -14.6 %
Total net sales           $ 1,670,137     $ 1,436,500     $ 233,637        16.3 %




The increase in net sales of wind blades was primarily driven by a 11% increase
in the number of wind blades produced during the year ended December 31, 2020 as
compared to the same period in 2019 as a result of increased production at our
China, Mexico, India and Iowa facilities. The increase was also due to a higher
average sales price due to the mix of wind blade models produced during the year
ended December 31, 2020 compared to the same period in 2019. Net sales from the
manufacturing of precision molding and assembly systems decreased, primarily in
Asia, during the year ended December 31, 2020 as compared to the same period in
2019, primarily due to our customers deferring a number of blade model
transitions due to the COVID-19 pandemic. Additionally, there was an increase in
transportation and other sales during the year ended December 31, 2020 as
compared to the same period in 2019. The fluctuating U.S. dollar against the
Euro in our Turkey operations and the Chinese Renminbi in our China operations
had a favorable impact of 0.1% on consolidated net sales for the year ended
December 31, 2020 as compared to 2019. Although our net sales increased for the
year ended December 31, 2020 compared to the same period in 2019, we estimate
that our net sales were adversely impacted by approximately $148.0 million,
based upon 352 wind blade sets, which we had forecasted to produce at our
Mexico, China, Iowa, Turkey and India manufacturing facilities in the periods
under non-cancellable purchase orders associated with our long-term contracts
but were unable to do so as a result of the COVID-19 pandemic. The COVID-19
pandemic required these manufacturing facilities to either temporarily suspend
production or operate at reduced production levels primarily during the first
and second quarters of 2020 as a result of certain applicable
government-mandated stay at home orders in response to the COVID-19 pandemic,
demands from certain of our labor unions to suspend or reduce production and
general safety concerns of our associates.

Total net sales            $ 181,941     $ 169,317     $ 12,624         7.5 %


The increase in the U.S. segment's net sales of wind blades was primarily due to
a 14% increase in the number of wind blades produced in the year ended
December 31, 2020 as compared to the same period in 2019, as well as a higher
average sales price due to the mix of wind blade models produced in the
comparable periods. Although our U.S. net sales increased for the year ended
December 31, 2020 compared to the same period in 2019, our U.S. net sales were
adversely impacted due to reduced production levels at our U.S. manufacturing
facilities due to the COVID-19 pandemic primarily during the second quarter of
2020.

Asia Segment


The following table summarizes our net sales by product/service for the Asia segment for the years ended December 31:






                                                              Change

                                      (in thousands)
Wind blade sales           $ 511,090     $ 366,206     $ 144,884        39.6 %
Precision molding and
  assembly systems sales      13,134        25,203       (12,069 )     -47.9 %
Other sales                    2,859         2,400           459        19.1 %
Total net sales            $ 527,083     $ 393,809     $ 133,274        33.8 %




The increase in the Asia segment's net sales of wind blades was primarily due to
a 22% net increase in the number of wind blades produced in the year ended
December 31, 2020 as compared to the same period in 2019 and an increase in the
average sales price of wind blades due to a change in the mix of wind blades
produced in the two comparative periods. Although our Asia net sales increased
for the year ended December 31, 2020 compared to the same period in 2019, our
Asia net sales were adversely impacted due to reduced production levels at our
Asia manufacturing facilities due to the COVID-19 pandemic primarily during the
first quarter of 2020. Net sales from the manufacturing of precision molding and
assembly systems during the 2020 period decreased by $12.1 million as compared
to the 2019 period primarily due to our customers deferring a number of blade
model transitions due to the COVID-19 pandemic.

                                                              Change
                             2020          2019           $            %
                                      (in thousands)
Wind blade sales           $ 472,994     $ 410,337     $ 62,657        15.3 %
Precision molding and
  assembly systems sales      14,939        19,703       (4,764 )     -24.2 %
Transportation sales           2,347           347        2,000          NM
Other sales                    5,559         5,219          340         6.5 %
Total net sales            $ 495,839     $ 435,606     $ 60,233        13.8 %




The increase in the Mexico segment's net sales of wind blades reflects a 18% net
increase in overall wind blade volume and an increase in the average sales price
of wind blades due to a change in the mix of wind blades produced in the two
comparative periods. In addition, our 2019 net sales were impacted by the
employees strike at our Matamoros production facility. Although our Mexico net
sales increased for the year ended December 31, 2020 compared to the same period
in 2019, our Mexico net sales were adversely impacted due to reduced production
levels at our Mexico manufacturing facilities due to the COVID-19 pandemic
primarily during the second quarter of 2020.

EMEA Segment

The following table summarizes our net sales by product/service for the EMEA segment for the years ended December 31:






                                                      Change
                     2020          2019            $            %
                              (in thousands)
Wind blade sales   $ 368,907     $ 431,362     $ (62,455 )     -14.5 %
Other sales            4,638         5,719        (1,081 )     -18.9 %
Total net sales    $ 373,545     $ 437,081     $ (63,536 )     -14.5 %




The decrease in the EMEA segment's net sales of wind blades was driven by a 22%
decrease in wind blade production at our two Turkey plants due to transitions
and reduced production levels at these manufacturing facilities due to the
COVID-19 pandemic primarily during the second quarter of 2020. The decrease was
partially offset by an increase in the average sales price of wind blades
delivered in the comparative periods and an increase in the year over year
number of wind blades still in the production process at the end of the period.
The fluctuating U.S. dollar relative to the Euro had a favorable impact of 0.3%
on net sales during the year ended December 31, 2020 as compared to the 2019
period.

Startup and transition costs        44,606          68,033       (23,427 )     -34.4 %
Total cost of goods sold       $ 1,606,038     $ 1,358,652     $ 247,386        18.2 %
% of net sales                        96.2 %          94.6 %                     1.6 %


Total cost of goods sold for the year ended December 31, 2020 was $1,606.0
million and included $25.9 million related to lines in startup and $18.7 million
related to lines in transition during the period. This compares to total cost of
goods sold for the year ended December 31, 2019 of $1,358.7 million and included
$48.5 million related to lines in startup and $19.5 million related to lines in
transition during the period. Cost of goods sold as a percentage of net sales
increased by approximately two percentage points during the year ended December
31, 2020 as compared to the same period in 2019, driven primarily by the
increase in warranty costs primarily relating to a remediation campaign for a
specific wind blade model for one of our customers, and COVID-19 related costs
associated with the health and safety of our associates and non-productive
labor, partially offset by a decrease in startup and transition costs, the
impact of savings in raw material costs and foreign currency fluctuations. The
fluctuating U.S. dollar against the Euro, Turkish Lira, Chinese Renminbi and
Mexican Peso had a favorable impact of 1.5% on consolidated cost of goods sold
for the year ended December 31, 2020 as compared to 2019.

General and administrative expenses





The following table summarizes our general and administrative expenses for the
years ended December 31:


                                                            Change
                             2020         2019          $            %
                                     (in thousands)
General and
 administrative expenses   $ 33,496     $ 39,916     $ (6,420 )     -16.1 %
% of net sales                  2.0 %        2.8 %                   -0.8 %




The decrease in general and administrative expenses as a percentage of net sales
for the year ended December 31, 2020 as compared to the same period in 2019 was
primarily driven by lower travel and training costs due to the COVID-19
pandemic.

Loss on sale of assets and asset impairments

The following table summarizes our loss on sale of assets and asset impairments for the years ended December 31:




                                                         Change
                          2020         2019           $            %
                                   (in thousands)
Loss on sale of assets
 and asset impairments   $ 7,748     $ 18,117     $ (10,369 )     -57.2 %
% of net sales               0.5 %        1.3 %                    -0.8 %


The decrease in the loss on sale of assets and asset impairments for the year
ended December 31, 2020 as compared to the same period in 2019 was primarily due
to: (i) a decrease of $4.4 million in asset impairment charges primarily related
to the shutdown of our second Newton, Iowa facility in 2019, (ii) a decrease of
$4.1 million in losses on the sale of assets at our corporate and manufacturing
facilities, and (iii) lower losses on the sale of receivables under supply chain
financing arrangements with our customers in the current year period due to
decreasing interest rates as compared to the equivalent prior year period.

Restructuring charges, net



Restructuring charges, net, for the year ended December 31, 2020 totaled $4.1
million. These charges primarily related to downsizing at our Dafeng, China
manufacturing facility, comprised of $3.8 million of severance benefits to
terminated employees, and $0.2 million of other charges, primarily related to
exit costs, at our second Newton, Iowa facility. The $3.8 million of severance
benefits relating to our Dafeng, China facility were paid to terminated
employees in January 2021. Restructuring charges, net, for the year ended
December 31, 2019 totaled $3.9 million. These charges primarily related to the
closing of our Taicang City, China manufacturing facility, comprised of $3.3
million of severance benefits to terminated employees and $0.6 million of other
charges, primarily related to exit costs.

Income (loss) from operations

Segment discussion

The following table summarizes our income (loss) from operations by our five geographic operating segments for the years ended December 31:




                                                       Change

U.S. Segment

The decrease in the loss from operations in the U.S. segment for the year ended
December 31, 2020 as compared to the same period in 2019 was primarily due to:
(i) the decreased costs related to the shutdown of our Newton, Iowa
transportation facility, (ii) the decrease in transition costs at our Newton,
Iowa blade facility, (iii) the increase in wind blade volume, (iv) the increase
in the average sales price of wind blades and (v) a decrease in general and
administrative expenses, partially offset by increased direct material costs at
our Newton, Iowa blade facility. Although our U.S. loss from operations
decreased for the year ended December 31, 2020 compared to the same period in
2019, our income from operations for the year ended December 31, 2020 was
adversely impacted due to reduced production levels at our U.S. blade
manufacturing facility due to the COVID-19 pandemic during the

                                       46

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

second quarter of 2020 and COVID-19 related costs associated with the health and safety of our associates and non-productive labor.

Asia Segment



The increase in the income from operations in the Asia segment for the year
ended December 31, 2020 as compared to the same period in 2019 was primarily due
to the net increase in overall wind blade volume and increase in the average
sales price of wind blades, a decrease in the startup and transition costs and
lower direct labor costs. The fluctuating U.S. dollar against the Chinese
Renminbi had an unfavorable impact of 0.3% on cost of goods sold for the year
ended December 31, 2020 as compared to the 2019 period. Although our Asia income
from operations increased for the year ended December 31, 2020 as compared to
the same period in 2019, our income from operations was adversely impacted due
to reduced production levels at our Asia manufacturing facilities due to the
COVID-19 pandemic during the first quarter of 2020 and COVID-19 related costs
associated with the health and safety of our associates and non-productive
labor.

Mexico Segment



The decrease in income from operations in the Mexico segment for the year ended
December 31, 2020 as compared to the same period in 2019 was primarily due to
increased warranty costs, the reduced production levels at our Mexico
manufacturing facilities due to the COVID-19 pandemic during the second quarter
of 2020 and COVID-19 related costs associated with the health and safety of our
associates and non-productive labor. These increased costs were partially offset
by the overall increase in wind blade volume, an increase in the average sales
price of wind blades, decreased startup and transition costs, favorable foreign
currency fluctuations as well as from savings in raw material costs. The
fluctuating U.S. dollar relative to the Mexican Peso had a favorable impact of
1.9% on cost of goods sold for the year ended December 31, 2020 as compared to
2019.

EMEA Segment

The decrease in income from operations in the EMEA segment for the year ended
December 31, 2020 as compared to the same period in 2019 was primarily driven by
increased warranty costs, decreased wind blade production at our two Turkey
manufacturing facilities due to the COVID-19 pandemic during the second quarter
of 2020 and COVID-19 related costs associated with the health and safety of our
associates and non-productive labor, the increased transition costs at one of
our Turkey manufacturing facilities, partially offset by favorable foreign
currency fluctuations. The fluctuating U.S. dollar relative to the Turkish Lira
and Euro had a favorable impact of 3.2% on cost of goods sold for the year ended
December 31, 2020 as compared to 2019.

India Segment





The increase in the loss from operations in the India segment for the year ended
December 31, 2020 as compared to the same period in 2019 was primarily due to
the increased startup costs related to our India manufacturing facility during
2020.

Other income (expense)



The following table summarizes our total other income (expense) for the years
ended December 31:


                                                               Change

Miscellaneous income             3,876        3,648           228         6.3 %
Total other expense          $ (26,509 )   $ (8,481 )   $ (18,028 )        NM


                                       47

--------------------------------------------------------------------------------
The increase in the total other expense for the year ended December 31, 2020 as
compared to the same period in 2019 was primarily due to increases in foreign
currency loss, net primarily due to net Euro liability exposure against the
Turkish Lira in the current year period as compared to the same period in 2019.



Income tax provision



The following table summarizes our income tax provision for the years ended
December 31:


                                                        Change
                         2020         2019           $            %
                                 (in thousands)
Income tax provision   $ 11,284     $ 23,115     $ (11,831 )     -51.2 %
Effective tax rate       -145.7 %      312.1 %


The decrease in the income tax provision for the year ended December 31, 2020 as
compared to the same period in 2019 was primarily due to tax benefits from the
effect of tax law changes and the release of valuation allowances in certain
jurisdictions, partially offset by lower pretax income related to the earnings
mix by jurisdiction and unrecognized tax benefits in the year ended December 31,
2020 as compared to the same period in 2019.

Net loss





The following table summarizes our net loss for the years ended December 31:


                                           Change
             2020         2019          $          %
                    (in thousands)
Net loss   $ 19,027     $ 15,708     $ 3,319       21.1 %


The increase in the net loss for the year ended December 31, 2020 as compared to
the same period in 2019 was primarily due to the reasons set forth above. In
addition, we estimate that our net loss during the year ended December 31, 2020
was adversely impacted by approximately $26.5 million, net of taxes, based upon
the forecasted gross margin on the wind blade sets we had forecasted to produce
at our Mexico, China, Iowa, Turkey and India manufacturing facilities in the
period under non-cancellable purchase orders associated with our long-term
contracts but were unable to do so as a result of the COVID-19 pandemic. The
COVID-19 pandemic required these manufacturing facilities to either temporarily
suspend production or operate at reduced production levels due primarily to
certain applicable government-mandated stay at home orders in response to the
COVID-19 pandemic, demands from certain of our labor unions to suspend or reduce
production and general safety concerns of our associates. In addition, during
the period we incurred $15.5 million, net of taxes, of COVID-19 related costs
associated with the health and safety of our associates and non-productive
labor. The diluted net loss per share was $0.54 for the year ended December 31,
2020, compared to a diluted net loss per share of $0.45 for the year ended
December 31, 2019.



Year Ended December 31, 2019 Compared to Year Ended December 31, 2018



For a comparison of our results of operations for the years ended December 31,
2019 and 2018, see "Management's Discussion and Analysis of Financial Condition
and Results of Operations-Results of Operations" included in Part II, Item 7 of
our Annual Report on Form 10-K for the year ended December 31, 2019, filed with
the SEC on March 2, 2020 incorporated herein by reference.

LIQUIDITY AND CAPITAL RESOURCES



As a result of the uncertainty relating to: (i) the rapidly evolving nature,
magnitude and duration of the COVID-19 pandemic, (ii) the variety of measures
implemented by governments around the world to address its effects and (iii) the
impact on our manufacturing operations, we have and will continue to manage our
liquidity to ensure our long-term viability until the COVID-19 pandemic
abates. During the year ended December 31, 2020, we had net borrowings of $58.7
million under our Credit Agreement. In addition, during the year ended
December 31, 2020, we entered into or amended four unsecured credit agreements
with four Turkish financial institutions resulting in net borrowings of $25.1
million and current availability of $52.9 million.

                                       48

--------------------------------------------------------------------------------
Our primary needs for liquidity have been, and in the future will continue to
be, capital expenditures, new facility startup costs, the impact of transitions,
working capital, debt service costs and warranty costs. Our capital expenditures
have been primarily related to machinery and equipment for new facilities or
facility expansions. Historically, we have funded our working capital needs
through cash flows from operations, the proceeds received from our credit
facilities and from proceeds received from the issuance of stock. We had net
borrowings under our financing arrangements of $75.7 million for the year ended
December 31, 2020 as compared to net repayments under our financing arrangements
of $2.1 million and $8.9 million for the years ended December 31, 2019 and 2018,
respectively. As of December 31, 2020 and 2019, we had $217.9 million and $142.1
million in outstanding indebtedness, excluding debt issuance costs,
respectively. As of December 31, 2020, we had an aggregate of $120.5 million of
remaining capacity and $94.2 million of remaining availability under our various
credit facilities. Working capital requirements have increased as a result of
our overall growth and the need to fund higher accounts receivable and inventory
levels as our business volumes have increased. Based upon current and
anticipated levels of operations, we believe that cash on hand, available credit
facilities and cash flow from operations will be adequate to fund our working
capital and capital expenditure requirements and to make required payments of
principal and interest on our indebtedness over the next twelve months.

We anticipate that any new facilities and future facility expansions will be
funded through cash flows from operations, the incurrence of other indebtedness
and other potential sources of liquidity. At December 31, 2020 and 2019, we had
unrestricted cash, cash equivalents and short-term investments totaling $129.9
million and $70.3 million, respectively. The December 31, 2020 balance includes
$61.0 million of cash located outside of the United States, including
$47.4 million in China, $6.0 million in Turkey, $5.0 million in India, $2.1
million in Mexico and $0.5 million in other countries. In February 2020, we
entered into an Incremental Facility Agreement with the current lenders to our
Credit Agreement and an additional lender, pursuant to which the aggregate
principal amount of our revolving credit facility under the Credit Agreement was
increased from $150.0 million to $205.0 million.

Our ability to repatriate funds from China to the United States is subject to a
number of restrictions imposed by the Chinese government. We repatriate funds
through several technology license and corporate/administrative service
agreements. We are compensated quarterly based on agreed upon royalty rates for
such intellectual property licenses and quarterly fees for those services.
Certain of our subsidiaries are limited in their ability to declare dividends
without first meeting statutory restrictions of China, including retained
earnings as determined under Chinese-statutory accounting requirements. Until
50% ($26.6 million) of registered capital is contributed to a surplus reserve,
our China operations can only pay dividends equal to 90% of after-tax profits
(10% must be contributed to the surplus reserve). Once the surplus reserve fund
requirement is met, our China operations can pay dividends equal to 100% of
after-tax profit assuming other conditions are met. At December 31, 2020, the
amount of the surplus reserve fund was $7.0 million.

Cash Flow Discussion

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

Operating Cash Flows





Net cash provided by operating activities decreased by $19.5 million for the
year ended December 31, 2020 as compared to the same period in 2019 primarily as
the result of decreased operating results and certain changes in our working
capital.

Investing Cash Flows



Net cash used in investing activities decreased by $9.8 million for the year
ended December 31, 2020 as compared to the same period in 2019 primarily as the
result of a decrease in capital expenditures.

We anticipate fiscal year 2021 capital expenditures of between $55 million to
$65 million and we estimate that the cost that we will incur after December 31,
2020 to complete our current projects in process will be approximately
$13.8 million. We have used, and will continue to use, cash flows from
operations, the proceeds received from our credit facilities and the proceeds
received from the issuance of stock for major projects currently being
undertaken, which include our manufacturing facility in Chennai, India and the
continued investment in our existing Turkey, Mexico, China and U.S. facilities.

Financing Cash Flows



Net cash provided by financing activities increased by $87.6 million for the
year ended December 31, 2020 as compared to the same period in 2019 primarily as
the result of increased borrowings on our revolving loans and other
growth-related debt, as well as increased proceeds from the exercise of stock
options.

Our Indebtedness

For a discussion of our indebtedness, refer to Note 11 - Long-Term Debt, Net of Debt Issuance Costs and Current Maturities of the Notes to Consolidated Financial Statements in Part II, Item 8 of this Annual Report on Form 10-K.

Other Contingencies



For a discussion of our legal proceedings, refer to Note 14 - Commitments and
Contingencies - (b) Legal Proceedings of the Notes to Consolidated Financial
Statements in Part II, Item 8 of this Annual Report on Form 10-K.

The wind blades and other composite structures that we produce are subject to
warranties against defects in workmanship and materials, generally for a period
of two to five years. We are not responsible for the fitness for use of the wind
blade or the overall wind turbine system. If a wind blade is found to be
defective during the warranty period as a result of a defect in workmanship or
materials, among other potential remedies, we may need to repair or replace the
wind blade (which could include significant transportation and installation
costs) at our sole expense. At December 31, 2020 and 2019, we had accrued
warranty reserves totaling $50.9 million and $47.6 million, respectively.

As of December 31, 2020, we had no material operating expenditures for environmental matters, including government imposed remedial or corrective actions, during the year ended December 31, 2020.

Off-Balance Sheet Transactions



We are not presently involved in any off-balance sheet arrangements, including
transactions with unconsolidated special-purpose or other entities that would
materially affect our financial position, results of operations, liquidity or
capital resources, other than our accounts receivable assignment agreements
described below. Furthermore, we do not have any relationships with
special-purpose or other entities that provide off-balance sheet financing;
liquidity, market risk or credit risk support; or engage in leasing or other
services that may expose us to liability or risks of loss that are not reflected
in the consolidated financial statements and related notes.

                                       50

--------------------------------------------------------------------------------
Our segments enter into accounts receivable assignment agreements with various
financial institutions. Under these agreements, the financial institution buys,
on a non-recourse basis, the accounts receivable amounts related to our
segment's customers at an agreed-upon discount rate.

The following table summarizes certain key details of each of the accounts receivable assignment agreements in place as of December 31, 2020:





Year Of Initial Agreement   Segment(s) Related To   Current Annual Interest Rate

CRITICAL ACCOUNTING POLICIES AND ESTIMATES



Our discussion and analysis of our financial condition and results of operations
are based upon our consolidated financial statements, which have been prepared
in accordance with GAAP. The preparation of these consolidated financial
statements requires us to make estimates and judgments that affect the reported
amount of our assets, liabilities, revenue and expenses and related disclosure
of contingent assets and liabilities. We evaluate our estimates on an ongoing
basis, including those related to income taxes and warranty expense. We base our
estimates on our historical experience and on various other assumptions that we
believe to be reasonable under the circumstances, the results of which form the
basis for making the judgments we make about the carrying values of our assets
and liabilities that are not readily apparent from other sources. Because these
estimates can vary depending on the situation, actual results may differ from
the estimates.

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

We believe the following critical accounting policies affect our more significant judgments used in the preparation of our consolidated financial statements.



Revenue Recognition. The majority of our revenue is generated from long-term
contracts associated with manufacturing of wind blades and related services. We
account for a long-term contract when it has the approval from both parties, the
rights of the parties are identified, payment terms are established, the
contract has commercial substance and the collectability of consideration is
probable. Our manufacturing services are customer specific and involve
production of items that cannot be sold to other customers due to the customers'
protected intellectual property.

Revenue is primarily recognized over time as we have an enforceable right to
payment upon termination and we may not use or sell the product to fulfill other
customers' contracts. Because control transfers over time, revenue is recognized
based on the extent of progress towards the completion of the performance
obligation under the cost-to-cost input measure of progress as this method
provides the best representation of the production progress towards satisfaction
of the performance obligation. Under the cost-to-cost method, progress and the
related revenue recognition is determined by a ratio of direct costs incurred to
date in fulfillment of the performance obligation to the total estimated direct
costs required to complete the performance obligation.

Determining the revenue to be recognized for services performed under our
manufacturing contracts involves judgments and estimates relating to the total
consideration to be received and the expected direct costs to complete the
performance obligation. Our estimates of variable consideration and
determination of whether to include estimated amounts in the transaction price
are based largely on an assessment of our anticipated performance and all
information available to us at the time of the estimate and may materially
change as additional information becomes known.

Under the cost-to-cost method, contract assets established primarily relate to
our rights to consideration for work completed but not billed at the reporting
date on manufacturing services contracts. The contract assets are transferred to
accounts receivable when the rights become unconditional, which generally occurs
when customers are invoiced upon the determination that a product conforms to
the contract specifications.

See Note 1 - Summary of Operations and Summary of Significant Accounting
Policies - (c) Revenue Recognition of the Notes to Consolidated Financial
Statements in Part II, Item 8 of this Annual Report on Form 10-K, for further
discussion of our accounting policies related to revenue recognition, including
accounting policies surrounding our non-manufacturing related services.

Income Taxes. In connection with preparing our consolidated financial
statements, we are required to estimate our income taxes in each of the
jurisdictions in which we operate. This process involves our assessment of any
net operating loss carryforwards, as well as estimating our actual current tax
liability together with assessing temporary differences resulting from differing
treatment of items, such as reserves and accrued liabilities, for tax and
accounting purposes. We also have to assess whether any portion of our earnings
generated in one taxing jurisdiction might be claimed as earned by income tax
authorities in a differing tax jurisdiction. Significant judgment is required in
determining our annual tax rate, the allocation of earnings to various
jurisdictions and the evaluation of our tax positions.

In the normal course of business, we establish valuation allowances for our
deferred tax assets when the realization of the assets is not more likely than
not. We intend to maintain such valuation allowances on our deferred tax assets
until there is sufficient evidence to support the reversal of all or some
portion of the allowances. Historically, we determined that a valuation
allowance for all of our U.S. deferred tax assets was appropriate, however
during the third quarter of 2018, we reversed a portion of the U.S. valuation
allowance, based on the available evidence at that time. In 2019 a full
valuation allowance was recorded in Taicang and India. Given our anticipated
future earnings in India from becoming fully operational in 2020, we reversed
the valuation allowance in that jurisdiction in 2020. The effect of a change in
judgment concerning the realizability of deferred tax assets is included in our
income tax provision.

                                       52

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

As of December 31, 2020, we have U.S. federal net operating losses (NOLs) of approximately $103.0 million, state NOLs of approximately $253.2 million, foreign NOLs of approximately $41.0 million and foreign tax credits of approximately $1.9 million available to offset future taxable income in the U.S., China and India.



In December 2017, the Tax Cuts and Jobs Act (Tax Reform) was signed into law,
which significantly revised U.S. tax law by, among other things, lowering the
statutory federal corporate income tax rate from 35% to 21% for tax years
beginning after December 31, 2017, eliminating certain deductions, imposing a
mandatory one-time transition tax, introducing new tax regimes, and changing how
foreign earnings are subject to U.S. tax. Tax Reform also includes many new
provisions, such as changes to bonus depreciation, changes to deductions for
executive compensation, interest expense limitations, NOL deduction limitations,
tax on global intangible low tax income (GILTI) earned by foreign corporate
subsidiaries, the base erosion anti abuse tax (BEAT), and a deduction for
foreign derived intangible income (FDII).

As of December 31, 2018, we completed the accounting for the enactment-date
income tax effects of Tax Reform, which resulted in an immaterial impact to our
financial statements. Upon further analyses of certain aspects of Tax Reform,
and refinement of calculations during 2018, we increased our provisional amount
of previously untaxed foreign earnings by $13.8 million, to $88.1 million. This
resulted in no change to our U.S. federal income tax expense due to the impact
of foreign tax credits. In addition, the provisional net tax expense, which was
estimated at approximately $0.1 million, primarily attributable to the reduction
in the federal tax rate, was unchanged and we made a policy election to account
for any impacts of GILTI tax in the period in which it is incurred.

Income tax expense or benefit, deferred tax assets and liabilities, and
liabilities for unrecognized tax benefits reflect our best estimate of current
and future taxes to be paid. We are subject to income taxes in both the U.S. and
numerous foreign jurisdictions in which we operate, principally, China, Mexico,
and Turkey. Significant judgements and estimates are required in determining our
consolidated income tax expense. The statutory federal corporate income tax rate
in the U. S. is 21% and the tax rates in China, Mexico and Turkey are 25%, 30%
and 22%, respectively. Our second Turkey facility is located in a tax-free zone
and is not subject to income taxes on earnings recognized from its manufacturing
activities.

Warranty Expense. The wind blades we manufacture are subject to warranties
against defects in workmanship and materials, generally for a period of two to
five years. We are not responsible for the fitness for use of the wind blade in
the overall wind turbine system. If a wind blade is found to be defective during
the warranty period as a result of a defect in workmanship or materials, among
other potential remedies, we may need to repair or replace the wind blade at our
sole expense. We provide warranties for all of our products with terms and
conditions that vary depending on the product sold. We record warranty expense
based upon our estimate of future repairs using a probability-based methodology
that considers previous warranty claims, identified quality issues and industry
practices. Once the warranty period has expired, any remaining unused warranty
accrual for the specific products is reversed against the current year warranty
expense amount.

Our estimate of warranty expense requires us to make assumptions about matters
that are highly uncertain, including future rates of product failure, repair
costs, availability of materials, shipping and handling, and de-installation and
re-installation costs at customers' sites, among others. When a potential or
actual warranty claim arises, we may accrue additional warranty reserves for the
estimated cost of remediation or proposed settlement. In 2020, we accrued
additional warranty expenses of approximately $12.9 million beyond the normal
warranty expense describe above related to a remediation campaign for a specific
wind blade model for one of our customers. We have not experienced any material
warranty expenses beyond the provision described above in the years ended
December 31, 2019 and 2018. However, changes in warranty reserves could have a
material effect on our consolidated financial statements. For example, as of
December 31, 2020, a change in the estimated warranty accrual rate of 1% across
all products would change the warranty accrual by approximately $42.5
million.
