lines, respectively, and although that weighed on our 2018 

results, we believe it positions us well for strong top- and 

bottom-line growth in 2019. As of February 28, 2019, we 

have approximately $6.8 billion of potential revenue under 

contract across 54 wind blade lines and our transportation 

manufacturing lines through 2023, with minimum aggregate 

volume commitments from our customers of approximately 

$4.0 billion.

In 2019, our primary focus should be and is on execution. 

We are expecting 14 lines to be in startup and 10 lines in 

transition during the year so laser-focused execution on 

these, as well as all other aspects of our operations, is

Item 1. Business

Description of Business

PART I

TPI Composites, Inc. is the holding company that conducts substantially all of its business operations through 

its direct and indirect subsidiaries (collectively, the Company or we). The Company was founded in 1968 and has 
been producing composite wind blades since 2001. The Company’s knowledge and experience of composite 
materials and manufacturing originates with its predecessor company, Tillotson Pearson Inc., a leading manufacturer 
of high-performance sail and powerboats along with a wide range of composite structures used in other industrial 
applications. Following the separation from the boat building business in 2004, the Company reorganized in 
Delaware as LCSI Holding, Inc. and then changed its corporate name to TPI Composites, Inc. in 2008.

Overview

We are the largest and only independent manufacturer of composite wind blades for the wind energy market 
with a global manufacturing footprint. We enable many of the industry’s leading wind turbine original equipment 
manufacturers (OEM), who have historically relied on in-house production, to outsource the manufacturing of some 
of their wind blades through our global footprint of advanced manufacturing facilities strategically located to serve 
large and growing wind markets in a cost-effective manner. Given the importance of wind energy capture, turbine 
reliability and cost to power producers, the size, quality and performance of wind blades have become highly 
strategic to our OEM customers. As a result, we have become a key supplier to our OEM customers in the 
manufacture of wind blades and related precision molding and assembly systems. We have entered into long-term 
supply agreements pursuant to which we dedicate capacity at our facilities to our customers in exchange for their 
commitment to purchase minimum annual volumes of wind blade sets, which consist of three wind blades. This 
collaborative dedicated supplier model provides us with contracted volumes that generate significant revenue 
visibility, drive capital efficiency and allow us to produce wind blades at a lower total delivered cost, while ensuring 
critical dedicated capacity for our customers. For a further discussion regarding our wind blade and precision 
molding and assembly system businesses, refer to the discussion in “Management’s Discussion and Analysis of 
Financial Condition and Results of Operations—Results of Operations” included in Part II, Item 7 of this Annual 
Report on Form 10-K.

We also leverage our advanced composite technology and history of innovation to supply high strength, 
lightweight and durable composite products to the transportation market.  In November 2017, we signed a five- year 
supply agreement with Proterra Inc. (Proterra) to continue to supply Proterra Catalyst® composite bus bodies from 
our existing Rhode Island facility and also from a new manufacturing facility in Newton, Iowa which commenced 
operations in the second quarter of 2018. In February 2018, we entered into an agreement with Navistar, Inc. 
(Navistar) to design and develop a Class 8 truck comprised of a composite tractor, trailer and frame rails. This 
collaborative development project was entered into in connection with Navistar’s recent award under the 
Department of Energy’s (DOE) Super Truck II investment program, which is designed to promote fuel efficiency in 
commercial vehicles. In November 2018, we announced a capital investment of approximately $11.5 million in 
2019 to develop a highly automated pilot manufacturing line for the electric vehicle market. We plan to locate this 
pilot line adjacent to our second Newton, Iowa location where we manufacture composite bus bodies for Proterra. 
We expect this investment will enable us to further develop our technology, create defensible product and process IP 
and demonstrate our capability to manufacture composite components cost effectively at automotive volume rates. 
We also expect this pilot line will also help our current and potential customers to de-risk the decision-making 
process to commit to TPI for high-volume manufacturing programs in the future.

Our wind blade and precision molding and assembly systems manufacturing businesses accounted for 
approximately 95%, 96%, and 97% of our total net sales for each of the years ended December 31, 2018, 2017 and 
2016, respectively.  As of February 28, 2019, our long-term wind and transportation supply agreements provide for 
minimum aggregate volume commitments from our customers of approximately $4.0 billion and encourage our 
customers to purchase additional volume up to, in the aggregate, a total contract value of approximately $6.8 billion 
through the end of 2023.

Public Offerings and Stock Split

In July 2016, we completed an initial public offering (IPO) of 7,187,500 shares of our common stock at a 
price of $11.00 per share, which included 937,500 shares issued pursuant to the underwriters’ over-allotment option. 
Certain of our existing stockholders, a non-employee director and executive officers purchased an aggregate of 
1,250,000 shares of our common stock in the IPO included in the total issuance above. The net proceeds from the 
IPO were $67.2 million after deducting underwriting discounts and offering expenses. Immediately prior to the 
closing of the IPO, all shares of the then-outstanding redeemable preferred shares converted into an aggregate 
of 21,110,204 shares of our common stock and the redeemable preferred share warrants converted on a net issuance 
basis into 120,923 shares of our common stock. In addition, concurrent with the closing of the IPO, certain 
subordinated convertible promissory notes in the aggregate principal and interest amount of $11.9 million were 
converted into 1,079,749 shares of our common stock at the public offering price of $11.00 per share.

Prior to the IPO, in July 2016 we amended our amended and restated certificate of incorporation to effect a 

360-for-1 forward stock split of our common stock. As a result of the stock split, we have adjusted the share 
amounts authorized and issuable under the share-based compensation plans. All share and per share common stock 
information (including the share-based compensation plans) referenced throughout the consolidated financial 
statements and notes thereto have been retroactively adjusted to reflect this stock split. The stock split did not cause 
an adjustment to the par value of the authorized shares of our common stock.

In May 2017, we completed a secondary public offering of 5,075,000 shares of our common stock at a price of 

$16.35 per share, which included 575,000 shares issued pursuant to the underwriters’ option to purchase additional 
shares. All of the shares were sold by existing stockholders and certain of our executive officers. The selling 
stockholders received all of the net proceeds of $78.8 million from the secondary public offering. We did not sell 
any shares and did not receive any of the proceeds from the offering and the costs paid by us in connection with the 
offering of $0.8 million were recorded in general and administrative costs in the accompanying consolidated income 
statement.  

Financial Information about Segments and Geographic Areas

We divide our business operations into four geographic operating segments—the United States (U.S.), Asia, 

Mexico, Europe, the Middle East, Africa and India (EMEAI) as follows:

India and we expect to commence operations at this facility in the first half of 2020.

For additional information regarding our operating segments and geographic areas, see Note 17 – Segment 
Reporting of the Notes to Consolidated Financial Statements included in Part II, Item 8 of this Annual Report on 
Form 10-K.

Business Strategy

Our long-term success will be driven by our business strategy. The key elements of our business strategy are 

as follows:

•

Grow our existing relationships and develop new relationships with leading industry OEMs. We plan 
to continue growing and expanding our relationships with existing customers who, according to data 
from Wood Mackenzie (WoodMac), represented approximately 54% of the global onshore wind energy 
market, approximately 90% of that market excluding China, and 99.8% of the U.S. onshore wind 
turbine market over the three years ended December 31, 2017, based on megawatts (MWs) of energy 
capacity installed, as well as developing new relationships with other leading industry OEMs. We 
expect to be presented with opportunities to expand our existing relationships and develop new 
relationships with industry OEMs as they seek to capitalize on the benefits of outsourced wind blade 
manufacturing while maintaining high quality customization and dedicated capacity. In March 2018, we 
entered into a multiyear supply agreement with Vestas Wind Systems A/S (Vestas) to supply wind 
blades from a new manufacturing facility in the Yangzhou Economic & Technical Development Zone in 
Yangzhou, China and we expect to commence operations at this facility in the first quarter of 2019. In 
May and July 2018, Vestas exercised its option for a total of four additional wind blade manufacturing 
lines under an existing multiyear supply agreement at our Matamoros, Mexico location and we 
commenced operations in the third quarter of 2018. In May 2018, we entered into a multiyear supply 
agreement with ENERCON GmbH (ENERCON) to supply wind blades from our second manufacturing 
facility in Izmir, Turkey and we commenced operations in the fourth quarter of 2018. In August 2018, 
General Electric International, Inc. and its affiliates (GE Wind) agreed to extend our existing multiyear 
supply agreement in one of our Mexico plants by two years to 2022 and increased the number of wind 
blade manufacturing lines in that facility from three to five.  In addition, GE Wind has agreed to 
transition to a larger blade model in our Newton, Iowa plant in early 2019 and to eliminate its option to 
terminate their supply agreement at this location prior to its December 2020 expiration. In December 
2018, we entered into a multiyear supply agreement with Vestas to supply wind blades from a new 
manufacturing facility that will be built near Chennai, India and we expect to commence operations at 
this facility in the first half of 2020. 

•

Expand our footprint in large and growing wind markets, capitalize on the continuing outsourcing 
trend, evaluate building wind turbine blades for the offshore market and evaluate strategic 
acquisitions. As the wind energy market continues to expand globally and many wind turbine OEMs 
continue to shift towards increased outsourcing of wind blade manufacturing, we believe we are well-
positioned to continue the expansion of our global footprint. We utilize our strengths in composites 
technology and manufacturing, combined with our collaborative dedicated supplier model to provide 
our customers with an efficient solution for their expansion in large and growing wind markets. Our 
quality, reliability and total delivered cost reduce sourcing risk for our customers. In addition, our 
demonstrated ability to expand into new markets and the strength of our manufacturing capabilities 
afford us the optionality to build new factories or grow through strategic acquisitions.

5

•

•

•

Continue to drive down costs of wind energy. We continue to work with our customers on larger size 
wind blade models that maximize the capture of wind energy and drive down the levelized cost of 
energy (LCOE). We also continue to utilize our advanced technology, regional manufacturing facilities 
strategically located to cost effectively serve large and growing wind markets and ability to source 
materials globally at competitive costs to deliver high-performing, composite wind blades. Our 
collaborative engineering approach and our advanced precision molding and assembly systems allow us 
to integrate our customer’s design requirements with cost-efficient, replicable and scalable 
manufacturing processes. This collaborative engineering approach with our customers also allows us to 
reduce manufacturing cycle times and new blade model transition times. We also continue to work with 
our customers to drive down the cost of materials and production, the benefit of which we typically 
share with our customers contractually in a manner that reduces LCOE for customers, further 
strengthens our customer relationships and improves our margins.

Expand our transportation business and expand into other strategic markets.  We leverage our 
advanced composite technology and history of innovation to supply high strength, lightweight and 
durable composite products to the transportation market. As the 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. As a result, we believe there is an increasing 
demand for composites products for electric vehicles. In addition, we believe there is a potential demand 
in other strategic markets for composites as to replace aluminum or other more expensive composite 
materials such as carbon.

Focus on continuing innovation. We have a history of innovation in advanced composite technologies 
and production techniques and use several proprietary technologies related to wind blade 
manufacturing. With this culture of innovation and a collaborative “design for manufacturability” 
approach, we continue to address increasing physical dimensions, demanding technical specifications 
and strict quality control requirements for our customers’ most advanced wind blades. We also invest in 
ongoing simplification and selective automation of production processes for increased efficiency and 
precision. In addition, we plan to leverage our history of composite industry-first innovations to grow 
our business in the transportation market, in which we believe there is a demand for high precision, 
structural composites manufacturing.

Wind Blade Manufacturing Operations and Process

We have developed significant expertise in advanced composite technology and use high performance 

composite materials, precision molding and assembly systems including modular tooling, and advanced process 
technology, as well as sophisticated measurement, inspection, testing and quality assurance tools, allowing us to 
produce over 45,000 wind blades since 2001 with an excellent field performance record in a market where reliability 
is critical to our customers’ success. We manufacture or have manufactured wind blades ranging from 30 meters to 
over 70 meters across our global facilities, and have the capability to manufacture wind blades of greater lengths as 
required by existing or new customers. In combination with our advanced technologies, we seek to create 
manufacturing processes that are replicable and scalable in our manufacturing facilities located worldwide, 
regardless of cultural or language barriers. Our integrated manufacturing process, the TPI Integrated Production 
System (TIPS) allows us to customize each manufacturing step, from raw materials to finished products. TIPS also 
allows us to systematically design for the entire manufacturing process so that we can achieve better quality control 
and increase production efficiencies. We believe that our focus on simplifying and, where feasible, automating 
production processes is critical to manufacturing high-precision, lightweight and durable products at a reasonable 
cost to our customers. We produce high unit volumes of near-aerospace grade products at industrial costs.

Raw Materials

The key raw materials for the wind blades we manufacture include highly advanced fiberglass fabrics, select 

carbon reinforcements, foam, balsa wood, resin, adhesives for assembly of molded components, gel coat or paint for 
preparation of cosmetic surfaces and attachment hardware including steel components. Most of these materials are 
available in multiple geographic regions and in reasonably close proximity to our manufacturing facilities. Our 
agreements for the supply of raw materials are designed to guarantee volumes that we believe will be required to 

6

fulfill our customers’ wind blade commitments. A portion of our raw materials are subject to price volatility, such as 
the resins used in our manufacturing processes. Although the majority of materials incorporated into our products 
are available from a number of sources, certain materials are available only from a relatively limited number of 
suppliers. We seek multiple suppliers for our raw materials and continually evaluate potential new supplier 
relationships.

Precision Molding and Assembly Systems

Over the last decade, we have produced hundreds of precision molding and assembly systems, ranging from 

30 meters to over 70 meters in length, to support our global operations. We began these operations in our tooling 
technology center in Warren, Rhode Island. In 2013, we expanded our precision molding and assembly system 
production capabilities to a facility in Taicang City, China, which serves customers around the globe. While capable 
of cost-effectively delivering precision molding and assembly systems across all of our facilities, our Rhode Island 
tooling technology center primarily serves the North American market. We are currently in the process of 
transitioning our North American precision molding and assembly system production capabilities from Warren, 
Rhode Island to a new facility in Juárez, Mexico, which can serve customers globally. We expect this transition to 
be completed by the end of 2019. Our precision molding and assembly systems have been used to build tens of 
thousands of wind blades worldwide.

Our tooling solutions include precision wind blade patterns, precision molding and assembly systems, 
including modular tooling techniques. We believe that our technological and production expertise are key factors in 
our continued competitiveness, as we address continually increasing physical dimensions, demanding technical 
specifications, and strict quality control requirements for wind blades.

Wind Blade Production Process

Production of wind blades requires adherence to the unique specifications of our customers, who design their 

wind turbines and wind blades to optimize performance, reliability and total delivered cost. With our culture of 
innovation and a collaborative “design for manufacturability” approach, we have the capability and expertise to 
manufacture wind blades of different designs, utilizing fiberglass, carbon or other advanced composite materials to 
meet unique customer specifications. We also have the flexibility to quickly transition our manufacturing facilities 
to produce different wind blade models and sizes using our precision molding and assembly systems, including 
modular tooling techniques.

We have developed a highly dependable method for making high-quality wind blades. In conjunction with our 
TIPS process, we design our proprietary manufacturing processes to be replicable, scalable and transferable to each 
of our advanced manufacturing facilities worldwide. As a result, we can repeatedly move a product from its design 
phase to volume production while maintaining quality, even in developing regions of the world. Similarly, we have 
developed the manual portions of our manufacturing processes based on proven technologies and production 
methods that can be learned and implemented rapidly by line personnel. We focus on consistency and quality 
control across our facilities, using hands-on training methods and employing repeatable manufacturing processes.

We use an advanced form of vacuum-assisted resin transfer tooling process to pull liquid resin into a dry lay-
up, resulting in light, strong, and reliable composite structures. In our manufacturing process, fiber reinforcements 
and core materials are laid up in a mold while dry, followed by a vacuum bag that is placed over the layup and 
sealed to the mold. The wind blade component is then placed under vacuum. The resin is introduced into the wind 
blade component via resin inlet ports and then distributed through the reinforcement and core materials via a flow 
medium and a series of channels, saturating the wind blade component. The vacuum removes air and gases during 
processing, thereby eliminating voids. Pressure differentials drive resin uniformly throughout the wind blade 
component, providing a consistent laminate. By using a variety of reinforcement and core materials, the structural 
characteristics of the wind blade can be highly engineered to suit the custom specifications of our customers. 
Although only occasionally required by our customers, we are also capable of employing additional composite 
fabrication processes, such as pre-impregnated laminates, in addition to our vacuum infusion process.

Wind Blade Long-Term Supply Agreements

Our current wind blade customers, which include GE Wind, Vestas, Siemens Gamesa Renewable Energy S.A. 

(Siemens Gamesa), Nordex SE (Nordex), Senvion S.A. (Senvion) and ENERCON, are some of the world’s largest 
wind turbine manufacturers. According to data from WoodMac, our customers represented approximately 54% of 
the global onshore wind energy market, approximately 90% of that market excluding China, and 99.8% of the U.S. 
onshore wind turbine market over the three years ended December 31, 2017, based on MWs of energy capacity 
installed. In our collaborative dedicated supplier model, our customers are incentivized to maximize the volume of 
wind blades purchased through lower pricing at higher purchase volumes. As of February 28, 2019, our existing 
wind blade supply agreements provide for minimum aggregate volume commitments from our customers of 
approximately $4.0 billion and encourage our customers to purchase additional volume up to, in the aggregate, a 
total contract value of approximately $6.8 billion through the end of 2023, which we believe provides us with 
significant future revenue visibility and helps to insulate us from potential short-term fluctuations or legislative 
changes in any one market. Our supply agreements generally contain liquidated damages provisions in the event of 
late delivery, however, we generally do not bear the responsibility for transporting the wind blades we manufacture 
to our customers.

GE Wind

In 2007, we entered into multiple supply agreements to build two facilities and manufacture wind blades for 

GE Wind in Taicang Port, China and Newton, Iowa. Based on the success of these manufacturing arrangements, we 
expanded our relationship with GE Wind through additional supply agreements for a manufacturing facility in 
Turkey and two manufacturing facilities in Mexico. Each of the supply agreements with GE Wind provide for a 
minimum number of wind blade sets to be purchased by GE Wind each year during the term, the schedule for which 
is established at the outset of the agreement. In return, we commit to dedicate a specific number of manufacturing 
lines to GE Wind for each of the years under the supply agreements. Additionally, we create model-specific tooling 
for GE Wind. For the year ended December 31, 2017, we recorded sales under these supply agreements with GE 
Wind of $426.1 million, $198.6 million of which was for the portion of 2017 that GE Wind was considered a related 
party. In 2017, GE Wind announced that they would not renew or extend the Turkey and Taicang Port, China supply 
agreements, which both expired on December 31, 2017. In August 2018, GE Wind did agree to extend our existing 
supply agreement in one of our Mexico plants by two years to 2022 and increased the number of wind blade 
manufacturing lines in that facility from three to five. In addition, GE Wind has agreed to transition to a larger blade 
model in our Newton, Iowa plant in early 2019 and to eliminate its option to terminate their supply agreement at this 
location prior to its December 2020 expiration. Unless otherwise terminated or renewed, our supply agreements with 
GE Wind are in effect until the end of 2020 for our Iowa and one of our Mexico facilities and until the end of 2022 
for our other Mexico facility. GE Wind may terminate the Mexico supply agreements with no advance notice and 
paying us termination fees as set forth in the applicable agreement. In addition, either party may terminate these 
supply agreements upon a material breach by the other party which goes uncured for 30 days after written notice has 
been provided. 

In 2017, General Electric Company (GE) completed its acquisition of LM Wind Power (LM), our largest 
competitor. We expect that GE Wind will utilize LM for a substantial percentage of its wind blade production in the 
future and may reduce the volumes of wind blades it purchases from us or not extend any of our supply agreements 
beyond 2022, which may materially harm our business, financial condition and results of operations. See “Risk 
Factors—Risks Related to Our Wind Blade Business—GE’s acquisition of LM Wind Power, our largest competitor, 
may materially harm our business, financial condition and results of operations and may cause the price of our 
common stock to decline” included in Part I, Item 1A of this Annual Report on Form 10-K for further discuss on the 
GE’s acquisition of LM and its potential effects on us.  

See Note 4 – Related Party Transactions of the Notes to Consolidated Financial Statements included in Part II, 

Item 8 of this Annual Report on Form 10-K for additional information regarding our related party transactions with 
GE Wind.

Other Long-Term Supply Agreements

We have entered into other long-term supply agreements in China, Mexico, Turkey and India. With respect to 

these supply agreements, we agree to dedicate capacity for a set number of wind blades for each calendar year 
during the term of the agreement in exchange for commitments to purchase minimum annual volumes of wind blade 
sets. Unless otherwise terminated, these supply agreements generally remain in effect for a period of five years and 
either party may terminate their respective supply agreements upon a material breach by the other party which goes 
uncured. Some of these supply agreements contain provisions that allow for our customers to purchase less volume 
in later years of these supply agreements, reduce the number of dedicated manufacturing lines or to terminate the 
supply agreement upon notice for reasons such as our failure to deliver the contracted wind blade volumes or our 
failure to meet certain mutually agreed upon cost reduction targets. See “Risk Factors—Risks Related to Our Wind 
Blade Business—Our long-term supply agreements with our customers are subject to termination on short notice 
and our failure to perform our obligations under such agreements, and termination of a significant number of these 
agreements would materially harm our business” included in Part I, Item 1A of this Annual Report on Form 10-K.

Research and Development

We have a long history of developing composite products as well as the development of new and advanced 
materials, tooling, manufacturing processes and inspection methods. Our knowledge and experience of composite 
materials and manufacturing originates with our predecessor company, Tillotson Pearson Inc., a leading 
manufacturer of high-performance recreational sail and powerboats along with a wide range of composite structures 
used in other industrial applications. Leveraging our knowledge and experience, we realized the opportunity to 
specialize in wind energy and other industrial end-markets where there was a demand for high precision composite 
manufacturing capabilities.

We conduct extensive research and development in close collaboration with our customers on the design, 
development and deployment of innovative manufacturing processes, including automation, advanced materials and 
sophisticated product quality inspection tools. We have partnered with the U.S. Department of Energy (DOE), 
government laboratories, universities and our customers to innovate through cost sharing Advanced Manufacturing 
Innovation Initiative programs. In 2015, we received a $3.0 million award from the DOE’s Office of Energy 
Efficiency & Renewable Energy to lead a team of industry and academic participants to design, develop and 
demonstrate an ultra-light composite vehicle door for high volume manufacturing production in conjunction with 
other industry and university participants. In February 2018, we entered into an agreement with Navistar to design 
and develop a Class 8 truck comprised of a composite tractor, trailer and frame rails. This collaborative development 
project was entered into in connection with Navistar’s recent award under the DOE’s Super Truck II investment 
program, which is designed to promote fuel efficiency in commercial vehicles.  Incorporating composite materials 
into a Class 8 truck offers multiple potential performance and efficiency advantages compared to traditional metals 
in terms of weight savings, reduced part counts, and non-corrosion. 

We employ a highly experienced workforce of engineers in various facets of our business, from discrete 
research and development projects, to the ongoing, real-time development and implementation of incremental 
manufacturing and material improvements. Our research and development effort places a priority on improving 
quality through process and procedure improvement, in addition to reducing cost through specification changes and 
sourcing of more cost-effective suppliers. Other areas of emphasis include composite design, in-house fabrication of 
precision molding and assembly systems, prototyping, testing, optimization and volume production capabilities. We 
also encourage our employees to invent and develop new technologies to maintain our competitiveness in the 
marketplace. In addition to our internal research and development activities, from time to time, we also conduct 
research and development activities pursuant to funded development arrangements with our customers and other 
third parties, and intend to continue to seek opportunities for product development programs that could create 
recurring revenue and increase our overall profitability over the long term.

For financial statement purposes, research and development performed is reflected in general and 

administrative expenses in our consolidated income statements.

Competition

The wind blade market is highly concentrated, competitive and subject to evolving customer needs and 
expectations. In 2017, GE Wind, our largest customer, completed its acquisition of LM, our largest competitor. We 
also compete primarily with other independent wind blade manufacturers such as Sinoma Science & Technology 
Co. Ltd., Shanghai Aeolon Wind Energy Technology Development (Group) Co., Ltd., Aeris Industria E Comercio 
De Equipamentos Para Geracao De Energia S.A. and ZhongFu Lianzhong Composites Group Co., Ltd., as well as 
regional wind blade suppliers in geographic areas where our current or prospective manufacturing facilities are 
located. 

We also compete with, and in a number of cases supplement, vertically integrated wind turbine OEMs that 
manufacture their wind blades. We believe that a number of other established companies are manufacturing wind 
blades that will compete directly with our offerings, and some of our competitors, including LM, Sinoma Science & 
Technology Co. Ltd., Aeris Industria E Comercio De Equipamentos Para Geracao De Energia S.A. and ZhongFu 
Lianzhong Composites Group Co., Ltd. may have significant financial and institutional resources.

The principal competitive factors in the wind blade market include reliability, total delivered cost, 

manufacturing capability, product quality, engineering capability and timely completion of wind blades. We believe 
we compete favorably with our competitors on the basis of the foregoing factors. Our ability to remain competitive 
will depend to a great extent upon our ongoing performance in the areas of manufacturing capability, timely 
completion and product quality.

Transportation Products

We seek to create additional recurring revenue opportunities through the supply of other composite structures 

outside the wind energy market. We believe transportation products, including buses, trucks, electric vehicles and 
high performance automotive products, are ideally suited for our advanced composite technology because of the 
benefits derived from weight reduction, corrosion resistance, strength and durability. These benefits should allow us 
to develop structural composite solutions to assist our customers in developing electric vehicles as well as buses 
with clean propulsion systems or in meeting new and developing fuel economy standards including the 2025 U.S. 
Government Corporate Average Fuel Economy standards that are pushing automakers to develop lighter, more fuel 
efficient vehicles with lower emissions. President Trump, however, issued an executive order in March 2017 
requiring the U.S. Environmental Protection Agency (EPA) to review the implementation timing and mileage targets 
of these standards. 

In addition, by producing a range of composite structures, we are able to leverage the materials and 
manufacturing process technology and expertise developed through one project to maximize production quality, 
improve performance and minimize costs across our other manufacturing efforts, including our wind blade business. 
Our projects for customers in the transportation market have historically generated project-related revenues for a 
specific duration. We intend to seek collaborations with additional customers in these markets that will provide 
recurring revenue and business opportunities for us, in addition to the opportunities provided by our existing 
customers and relationships, and contribute to our overall profitability over the long term. 

Our facilities in Warren, Rhode Island and Newton, Iowa manufacture products for customers in the 
transportation market using a similar proprietary and replicable manufacturing processes that we use to produce 
wind blades. Our projects for customers in the transportation market include, or have included, the supply of all-
composite bodies for electric buses and automated people mover systems for airports. 

Our current principal competitors in the transportation market include suppliers of conventional steel and 

aluminum products and non-structural automotive fiberglass and other advanced composites-based manufacturers 
for transportation applications.

Intellectual Property

We have a variety of intellectual property rights, including patents (filed and applied-for in a number of 
jurisdictions, including the United States, the European Union and China), trademarks and copyrights, but we 
believe that our continued success and competitive position depend, in large part, on our proprietary materials, 
tooling, process and inspection technologies and our ability to innovate. Accordingly, we take measures to protect 
the confidentiality and control the disclosure of our proprietary technology. We rely primarily on a combination of 
patents, know-how and trade secrets to establish and protect our proprietary rights and preserve our competitive 
position. We also seek to protect our proprietary technology, in part, by confidentiality agreements with our 
customers, employees, consultants and other contractors. Trade secrets, however, are difficult to protect. These 
agreements may be breached, and we may not have adequate remedies for any breach. In addition, our trade secrets 
may otherwise become known or be independently discovered by competitors. To the extent that our customers, 
employees, consultants or contractors use intellectual property owned by others in their work for us, disputes may 
arise as to the rights in related or resulting know-how and inventions.

Backlog

As of December 31, 2018 and 2017, our backlog for wind blades and related products totaled $514.8 million 

and $555.8 million, respectively. Our backlog includes purchase orders issued in connection with our long-term 
supply agreements. We generally record a purchase order into backlog when the following requirements have been 
met: a signed long-term supply agreement or other contractual agreement has been executed with our customer, a 
purchase order has been issued by our customer and we expect to ship wind blades to or produce the related 
products for such customer in satisfaction of any purchase order within 12 months. Backlog as of any particular date 
should not be relied upon as indicative of our revenue for any future period. 

Regulation

Wind Energy

Our operations are subject to various foreign, federal, state and local regulations related to environmental 
protection, health and safety, labor relationships, general business practices and other matters. These regulations are 
administered by various foreign, federal, state and local environmental agencies and authorities, including the EPA, 
the Occupational Safety and Health Administration of the U.S. Department of Labor and comparable agencies in 
China, Mexico, Turkey, India and individual U.S. states. In addition, our manufacturing operations in China, 
Mexico, Turkey and India are subject to those countries’ wage and price controls, currency exchange control 
regulations, investment and tax laws, laws restricting our ability to repatriate profits, trade restrictions and laws that 
may restrict foreign investment in certain industries. Some of these laws have only been recently adopted or are 
subject to further rulemaking or interpretation, and their impact on our operations, including the cost of complying 
with these laws, is uncertain. We believe that our operations currently comply, in all material respects, with 
applicable laws and regulations. Further, as a U.S. corporation, we are subject to The Foreign Corrupt Practices Act 
of 1977 (FCPA), which generally prohibits U.S. companies and their intermediaries from making improper 
payments to foreign officials for the purpose of obtaining or keeping business.

In addition, our business has been and will continue to be affected by subsidization of the wind turbine 
industry with its influence declining over time as wind energy reaches grid parity with traditional sources of energy. 
In the United States, the federal government has encouraged capital investment in renewable energy primarily 
through tax incentives. Production tax credits for new renewable energy projects were first established in 1992. The 
Production Tax Credit for Renewable Energy (PTC) provided the owner of a wind turbine placed in operation before 
January 1, 2015 with a 10-year credit against its U.S. federal income tax obligations based on the amount of 
electricity generated by the wind turbine.

The PTC was extended in 2015 for wind power projects through December 31, 2019, and is currently 
contemplated to be phased down over the term of the PTC extension. Specifically, the PTC will be kept at the same 
rate in effect at the end of 2014 for wind power projects that either commenced construction or met certain safe 
harbor requirements by the end of 2016, and thereafter will be reduced by 20% per year in 2017, 2018 and 2019, 
respectively. 

11

In 2015, the EPA announced a final rule adopted pursuant to the Clean Air Act, known as the Clean Power 

Plan, which establishes national standards for states to reduce carbon emissions from power plants. Specifically, the 
Clean Power Plan requires states to reduce carbon emissions from power plants 32% below 2005 levels by 2030. 
The Clean Power Plan also provides for interim state-level compliance reduction targets beginning in 2022 through 
2030 based on individualized targets for each of the states utilizing 2012 historical carbon emissions data and three 
building blocks for emissions reduction including: increasing generation from new zero-emitting renewable energy 
sources such as wind. In 2016, the U.S. Supreme Court issued a stay of the EPA’s implementation of the Clean 
Power Plan until the D.C. Circuit of the United States Court of Appeals decides upon the merits of multiple lawsuits 
challenging the legality of the Clean Power Plan. In 2017, President Trump signed an executive order that requires, 
among other things, that the EPA review the Clean Power Plan and publish a rule to either suspend, revise or rescind 
it. 

At the state level, as of December 31, 2018, 29 states, the District of Columbia and Puerto Rico have 
implemented renewable portfolio standard (RPS) programs that generally require that, by a specified date, a certain 
percentage of a utility’s electricity supplied to consumers within such state is to be from renewable sources (ranging 
from 10% to 100% and from between the present and 2045).

In addition, there are also increasing regulatory efforts to promote renewable power. China is implementing its 

13th 5-Year Plan with a goal of 15% total primary energy from non-fossil fuel sources and targeting 210 gigawatts 
(GWs) of grid-connected wind capacity by 2020 according to its National Development and Reform Commission, 
and employs preferential feed-in tariff schemes, in addition to local tax-based incentives. Mexico has established 
strict targets, aiming for 35% renewable energy by 2024 and 50% by 2050, according to WoodMac, which it is 
facilitating through tax incentives. Large European Union members have renewable energy targets for 2020 of 
between 13% and 49% of all energy use derived from renewable energy sources, according to WoodMac. 
Additionally, Turkey enacted Law No. 5346 in 2005 to promote renewable-based electricity generation within their 
domestic electricity market by introducing tariffs and purchase obligations for distribution companies requiring 
purchases from certified renewable energy producers. The World Bank also provided Turkey with an aggregate of 
$600 million of loan proceeds to encourage investors to construct generation plants with renewable energy 
resources. 

Employees

As of December 31, 2018, we employed over 10,600 full-time employees, approximately 1,300 of whom were 

located in the United States, 2,400 in China, 4,100 in Mexico and 2,800 in Turkey. Certain of our employees in 
Turkey and at our manufacturing facility in Matamoros, Mexico are represented by a labor union. We believe that 
our relations with our employees are generally good.

In January 2019, thousands of workers employed in dozens of manufacturing facilities in Matamoros, Mexico, 

went on strike.  In general, these workers, who were represented by several different labor unions, demanded a 
twenty percent increase in their wage rate and an annual bonus of approximately $1,700. On February 15, 2019, our 
manufacturing production employees in Matamoros, Mexico, who are represented by a labor union, went on strike 
also demanding a 20 percent increase in their hourly wage rate and the payment of an annual bonus of 
approximately $1,700 even though our collective bargaining agreement does not provide for an annual bonus. 
During this strike, our Matamoros manufacturing facility stopped production from February 15, 2019 until March 2, 
2019. On March 2, 2019, we reached an agreement with the labor union to end the strike and we reopened our 
Matamoros manufacturing facility on March 3, 2019.

Item 1A. Risk Factors

You should carefully consider the following risk factors. If any of the events contemplated by the following 

discussion of risks should occur, our business, results of operations, financial condition, growth prospects and cash 
flows could suffer significantly. Additional risks that we currently do not know about or that we currently believe to 
be immaterial may also impair our business. Certain statements below are forward-looking statements. See “Special 
Note Regarding Forward-Looking Statements” in this Annual Report on Form 10-K.  

Risks Related to Our Wind Blade Business

A significant portion of our business is derived from a small number of customers, and two wind blade customers 
in particular, therefore any loss of or reduction in purchase orders, failure of these customers to fulfill their 
obligations or our failure to secure long-term supply agreement renewals from these customers could materially 
harm our business.

Substantially all of our revenues are derived from four wind blade customers. Two customers, GE Wind and 
Vestas, accounted for 31.7% and 32.0%, respectively, of our total net sales for the year ended December 31, 2018, 
44.6% and 27.9%, respectively, of our total net sales for the year ended December 31, 2017, and 48.4% and 22.2%, 
respectively, of our total net sales for the year ended December 31, 2016. In addition, two customers, Nordex and 
Siemens Gamesa accounted for 19.0% and 11.2%, respectively, of our net sales for the year ended December 31, 
2018, 16.0% and 9.7%, respectively, of our net sales for the year ended December 31, 2017, and 18.0% and 10.2%, 
respectively, of our net sales for the year ended December 31, 2016. Accordingly, we are substantially dependent on 
continued business from our current wind blade customers, and GE Wind and Vestas in particular. If one or more of 
our wind blade customers were to reduce or delay wind blade orders, file for bankruptcy or become insolvent, fail to 
pay amounts due or satisfactorily perform their respective contractual obligations with us or otherwise terminate or 
fail to renew their long-term supply agreements with us, our business, financial condition and results of operations 
could be materially harmed.

Defects in materials and workmanship or wind blade failures could harm our reputation, expose us to product 
warranty or other liability claims, decrease demand for wind blades we manufacture, or materially harm existing 
or prospective customer relationships.

Defects in the wind blades we manufacture, whether caused by a design, engineering, materials, 
manufacturing or component failure or deficiencies in our manufacturing processes, are unpredictable and an 
inherent risk in manufacturing technically advanced products. Under our supply agreements, we warranty the 
materials and workmanship of the wind blades while our customers are responsible for the fitness of use and design 
of the wind blades. We have, in the past, experienced wind blade testing failures and defects at some of our facilities 
during the startup manufacturing phase of new products, and we may experience failures or defects in the future. We 
have also experienced wind blade failures in the field. Any such customer qualification and wind blade testing 
failures or other product defects in the future could materially harm our existing and prospective customer 
relationships. Specifically, negative publicity about the quality of the wind blades we manufacture or defects in the 
wind blades supplied to our customers could result in a reduction in wind blade orders, increased warranty claims, 
product liability claims and other damages or termination of our long-term supply agreements or business 
relationships with current or new customers. In addition, we have recently started wind blade production at a new 
facility in Mexico and plan to start wind blade production at a new facility in Yangzhou, China in the first quarter of 
2019 and at a new facility near Chennai, India in the first half of 2020 which may expose us to greater risk of 
warranty claims as these facilities ramp up to serial production levels. 

We may determine that resolving potential warranty claims through a negotiated settlement may be in the best 

interest of the business and long-term customer relationships. Wind blades may also fail due to lightning strikes or 
other extreme weather, which could also result in negative publicity regarding our wind blades and wind energy in 
general. In addition, product defects may require costly repairs or replacement components, a change in our 
manufacturing processes or recall of previously manufactured wind blades, which could result in significant expense 
and materially harm our existing or prospective customer relationships. Further, defects or product liability claims, 
with or without merit, may result in negative publicity that could harm our future sales and our reputation in the 
industry. Any of the foregoing could materially harm our business, operating results and financial condition.

15

We have experienced, and could in the future experience, quality or operational issues in connection with plant 
construction or expansion, wind blade model transitions and wind blade manufacturing, which could result in 
losses and cause delays in our ability to complete our projects and may therefore materially harm our business, 
financial condition and results of operations.

We dedicate most of the capacity of our current wind blade manufacturing facilities to existing customers and, 
as a result, we may need to build additional manufacturing capacity or facilities to serve the needs of new customers 
or expanded needs of existing customers. Since the third quarter of 2016, we have commenced operations at three 
new manufacturing facilities in Mexico, one in Turkey and one in Iowa. In March 2018, we signed a lease for the 
construction of a new manufacturing facility in the Yangzhou Economic & Technical Development Zone in 
Yangzhou, China and we expect to commence operations at this facility in the first quarter of 2019. Also, in 
February 2019, we signed a lease for a new manufacturing facility that will be built near Chennai, India and we 
expect to commence operations at this facility in the first half of 2020. The construction of new plants and the 
expansion of existing plants involves significant time, cost and other risks. We expect our plants to generate losses 
in their first 12 to 24 months of operations related to production startup costs. Additionally, numerous factors can 
contribute, and have in the past contributed, to delays or difficulties in the startup of, or the adoption of our 
manufacturing lines to produce larger wind blade models, which we refer to as model transitions, in our 
manufacturing facilities. These factors include permitting, construction or renovation delays, the engineering and 
fabrication of specialized equipment, the modification of our general production know-how and customer-specific 
manufacturing processes to address the specific wind blades to be tested and built, changing and evolving customer 
specifications and expectations and the hiring and training of plant personnel. If our production or the delivery by 
any third-party suppliers of any custom equipment is delayed, the construction or renovation of the facility, or the 
addition of a production line would be delayed. Any delays or difficulties in plant startup or expansion may result in 
cost overruns, production delays, contractual penalties, loss of revenues, reduced margins and impairment of 
customer relationships, which could materially harm our business, financial condition and results of operations.

Some of our long-term supply agreements with our customers are subject to early termination and our failure to 
perform our obligations under these agreements or the termination of these agreements would materially harm 
our business, financial condition and results of operation.  

Our current long-term supply agreements expire between the end of the second quarter of 2020 and the end of 

2023. Some of our long-term supply agreements contain provisions that allow for the early termination of these 
agreements upon the customer providing us with advance written notice and paying an early termination fee.  
Additionally, our long-term supply agreements contain provisions allowing our customers to terminate these 
agreements upon our failure to deliver the contracted wind blade volumes or our failure to meet certain mutually 
agreed upon cost reductions. Our customers may not continue to maintain long-term supply agreements with us in 
the future. If one or more of our customers terminate, or reduce the number of lines or fail to renew their long-term 
supply agreements with us, it would materially harm our business, financial condition and results of operations.

Our long-term supply agreements and our backlog are subject to reduction within contractual parameters and we 
may not realize all of the expected revenue.

Our current long-term wind blade supply agreements generally establish annual purchase requirements on 
which we rely for our future production and financial forecasts. However, the timing and volume of purchases, 
within certain parameters, may be subject to change by our customers.  In addition, the amount of the annual 
purchase requirements typically decline in the later years of our long-term supply agreements. In some instances, 
our customers have the contractual right to require us to reduce the number of manufacturing lines committed to 
them and correspondingly reduce their minimum annual purchase requirements. Additionally, our minimum annual 
purchase commitments could potentially 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. Such minimum annual purchase requirements could also potentially overstate the forecasted net sales 
that we are likely to generate in a given period or periods if one or more of our long-term supply agreements were to 
be terminated by our customers for any reason. As a result, we may not realize the forecasted net sales we expect 
under our long-term supply agreements or pursuant to our backlog, which we define as the value of purchase orders 
received less the revenue recognized to date on those purchase orders. In addition, fulfillment of our backlog may 
not result in profits.

16

Many of our long-term supply agreements contain liquidated damages provisions, which may require us to make 
unanticipated payments to our customers.

Many of our long-term supply agreements contain liquidated damages provisions in the event that we fail to 

perform our obligations thereunder in a timely manner or in accordance with the agreed terms, conditions and 
standards. Our liquidated damages provisions generally require us to make a payment to the customer if we fail to 
deliver a product or service on time. We generally try to limit our exposure under any individual long-term supply 
agreement to a maximum penalty. Nevertheless, if we incur liquidated damages, they may materially harm our 
business, operating results and financial condition. 

Our wind turbine OEM customers are facing increasing competition and pricing pressure due to the increasing 
prevalence of auction-based tenders in wind energy markets, and correspondingly our margins and results of 
operations may be adversely affected. 

Many governments are shifting from feed-in tariffs to auction-based tenders as a means of promoting the 

development and growth of renewable energy sources such as wind energy.  As a result of this shift, our wind 
turbine OEM customers are experiencing intense pricing pressure with respect to the sale of their turbines. As a 
result of this pricing pressure, we will be required to further reduce the costs we incur to manufacture wind blades to 
remain competitive.  We typically share the benefit of cost reductions related to manufacturing wind blades with our 
customers pursuant to the terms of our long-term supply agreements.  If these pricing pressures continue, we may 
choose to reduce our margins or pass on a greater percentage of the savings to our OEM customers obtained from 
manufacturing cost reductions than required under our supply agreements to remain competitive, each of which may 
materially harm our business, financial condition and results of operations.

Although a majority of our manufacturing facilities are located outside the United States, our business is still 
heavily dependent upon the demand for wind energy in the United States and any downturn in demand for wind 
energy in the United States could materially harm our business.

We have developed a global footprint to serve the growing wind energy market worldwide and have wind 
blade manufacturing facilities in the United States, China, Mexico, Turkey and India. Although a majority of our 
manufacturing facilities are located outside of the United States, historically more than half of the wind blades that 
we produced were deployed in wind farms located within the United States. Our Iowa and Mexico manufacturing 
facilities manufacture wind blades that are generally deployed within the United States. In addition, we export wind 
blades from our China and Turkey manufacturing facilities to the United States and wind blades that will be 
produced at our India manufacturing facility could be exported by our customers to the United States as well. 
Consequently, demand for wind energy and our wind blade sales in the United States could be adversely affected by 
a variety of reasons and factors, and any downturn in demand for wind energy and our wind blade sales in the 
United States could materially harm our business.

We could experience shortages of raw materials or components critical to our manufacturing needs, which may 
hinder our ability to perform under our supply agreements.

We rely upon third parties for raw materials, such as fiberglass, carbon, resins, foam core and balsa wood, and 
various components for the wind blades we manufacture. Some of these raw materials and components may only be 
purchased from a limited number of suppliers. For example, balsa wood is only grown and produced in a limited 
number of geographies and is only available from a limited number of suppliers. Additionally, our ability to 
purchase the appropriate quantities of raw materials is constrained by our customers’ transitioning wind blade 
designs and specifications. As a result, we maintain relatively low inventory and acquire raw materials and 
components as needed. Due to significant international demand for these raw materials from many industries, we 
may be unable to acquire sufficient quantities or secure a stable supply for our manufacturing needs. If shortages or 
delays occur, we may be unable to provide our products to our customers on time, or at all. In some instances, our 
customers directly control the purchase of certain key raw materials and components and if they are unable to 
procure and provide us with such raw materials and components, it could cause delays and disruptions with respect 
to our business and operations. In addition, a disruption in any aspect of our global supply chain caused by 
transportation delays, customs delays, cost issues or other factors could result in a shortage of raw materials or 
components critical to our manufacturing needs. Any supply shortages, delays in the shipment of materials or 
components from third party suppliers, or changes in the terms on which they are available could disrupt or 
materially harm our business, operating results and financial condition.

17

We operate in an industry characterized by changing customer demands and associated transition costs, which 
could materially harm our business.

The wind energy industry is competitive and is characterized by evolving customer demands. As a result, we 
must adapt quickly to customer requests for changes to wind blade specifications, which increases our costs and can 
provide periods of reduced revenue and margins. For instance, during 2018 and into 2019, we have undertaken and 
will undertake model transitions at several of our facilities for various customer demands. In 2018 we had 15 
manufacturing lines in transition which impacted our revenue growth. We currently expect to have 10 
manufacturing lines in transition during 2019 which could adversely affect our revenue growth and profitability in 
2019. We are generally able to share transition costs with the customer in connection with these changing customer 
demands, but any sharing is the subject of negotiation and the amount is not always contractually defined. If we do 
not receive transition payments from our customers sufficient to cover our transition costs or lost margins, our 
business, financial condition and results of operations could be materially harmed.

The concentration of customers in our wind business could enable one or more of our customers to attempt to 
substantially influence our policies, business and affairs going forward, or adversely affect our business, 
financial condition or results of operations if one or more of our customers experience financial difficulties, 
become insolvent or file for bankruptcy. 

Our dependence on six wind blade customers for substantially all of our revenues could encourage these 

customers to attempt to impose new or additional requirements on us that reduce the profitability of our long-term 
supply agreements with them or otherwise influence our policies, choice of and arrangements with raw material 
suppliers and other aspects of our business. Our customers could also attempt to influence the outcome of a 
corporate transaction if the transaction benefits a customer’s competitor or is otherwise perceived as not 
advantageous to a customer, which could have the effect of delaying, deterring, or preventing a transaction that 
could benefit us. In addition, consolidation of some of our customers may result in increased customer concentration 
and the potential loss of customers. For example, Nordex completed its acquisition of Acciona in 2016 and Gamesa 
completed the merger of Siemens’ Wind Power with Gamesa in 2017. Although we are not constrained by any 
exclusivity agreements with any of our existing wind blade customers, they may resist our development of new 
customer relationships, which could affect our relationships with them or our ability to secure new customers.

In addition, if one or more of our customers experience financial difficulties, demand for the wind blades we 

manufacture could decline significantly. In such a circumstance, we could also be at risk of collecting accounts 
receivable amounts owed from such customers as well as realizing the value of inventory balances for such 
customers. Similarly, if one or more of our customers becomes insolvent or files for bankruptcy, the demand for the 
wind blades we manufacture from the affected customers could be eliminated altogether.  If any of our customers 
experience financial difficulties, they also may seek pricing concessions, extended payment terms, reduced 
minimum purchase commitments and other changes to the key terms of our supply agreements that could adversely 
affect our business, financial condition and results of operations.     

Demand for the wind blades we manufacture may fluctuate for a variety of reasons, including the growth of the 
wind industry, and decreases in demand could materially harm our business and may not be sufficient to support 
our growth strategy.

Our revenues, business prospects and growth strategy heavily depend on the continued growth of the wind 

industry and our customers’ continuing demand for wind blades. Customer demand could decrease from anticipated 
levels due to numerous factors outside of our control that may affect the development of the wind energy market 
generally, portions of the market or individual wind project developments, including:

•

•

•

•

general economic conditions;

the general availability and demand for electricity;

wind energy market volatility;

cost-effectiveness, availability and reliability of alternative sources of energy and competing methods of 
producing electricity, including solar and non-renewable sources such as natural gas;

18

•

•

•

•

•

•

•

foreign, federal and state governmental subsidies and tax or regulatory policies;

delays or cancellations of government tenders or auctions for wind energy projects;

the availability of financing for wind development projects;

the development of electrical transmission infrastructure and the ability to implement a proper grid 
connection for wind development projects;

foreign, federal and state laws and regulations regarding avian protection plans, noise or turbine setback 
requirements and other environmental laws and regulations;

administrative and legal challenges to proposed wind development projects; and

public perception and localized community responses to wind energy projects.

In addition to factors affecting the wind energy market generally, our customers’ demand may also fluctuate 

based on other factors beyond our control. Any decline in customer demand below anticipated levels could 
materially harm our revenues and operating results and could delay or impede our growth strategy.

Changes in customers’ business focus and strategy could materially harm our business and results of operations.

Changes in our customers’ business focus could significantly reduce their demand for wind blades. For 
instance, GE, the parent corporation of GE Wind, is a highly diversified company that operates in a number of 
different industries and could decide to devote more resources to operations outside of wind energy or cease selling 
wind turbines altogether. In addition, we expect that GE Wind will utilize LM for a substantial percentage of its 
wind blade production in the future. If any of our customers change their business focus, including a strategic shift 
to insource a material portion of its wind blade production requirements, it could materially harm our business and 
results of operations.

We have experienced in the past, and our future wind blade production could be affected by, operating problems 
at our facilities, which may materially harm our operating results and financial condition.

Our wind blade manufacturing processes and production capacity have in the past been, and could in the 

future be, disrupted by a variety of issues, including:

•

•

•

•

•

•

•

•

production outages to conduct maintenance activities that cannot be performed safely during operations;

prolonged power failures or reductions;

breakdowns, failures or substandard performance of machinery and equipment;

our inability to comply with material environmental requirements or permits;

inadequate transportation infrastructure, including problems with railroad tracks, bridges, tunnels or 
roads;

supply shortages of key raw materials and components;

damage or production delays caused by earthquakes, fires, floods, tornadoes, hurricanes, extreme 
weather conditions such as windstorms, hailstorms, drought, temperature extremes, typhoons or other 
natural disasters or terrorism; and

labor unrest.

The cost of repeated or prolonged interruptions, reductions in production capacity, or the repair or replacement 

of complex and sophisticated tooling and equipment may be considerable and could result in damages under or the 
termination of our long-term supply agreements or penalties for regulatory non-compliance, any of which could 
materially harm our business, operating results and financial condition.

19

We operate a substantial portion of our business in international markets and we may be unable to effectively 
manage a variety of currency, legal, regulatory, economic, social and political risks associated with our global 
operations and those in developing markets.

We currently operate manufacturing facilities in the United States, China, Mexico and Turkey, and we are 
expanding our operations to India to meet customer demand in India. Since 2016, we have commenced operations at 
three new manufacturing facilities in Mexico, one in Turkey and one in Iowa. In March 2018, we signed a lease to 
construct a new manufacturing facility in the Yangzhou Economic & Technical Development Zone in Yangzhou, 
China and we expect to commence operations at this facility in the first quarter of 2019. Also, in February 2019, we 
signed a lease to construct a new manufacturing facility that will be built near Chennai, India and we expect to 
commence operations at this facility in the first half of 2020. For the years ended December 31, 2018, 2017 and 
2016, approximately 84%, 80% and 75%, respectively, of our net sales were derived from our international 
operations and we expect that a substantial portion of our projected revenue growth will be derived from those 
operations. Our overall success depends, in part, upon our ability to succeed in differing legal, regulatory, economic, 
social and political conditions. The global nature of our operations is subject to a variety of risks, including:

•

•

•

•

•

•

•

•

•

•

•

•

•

difficulties in staffing and managing multiple international locations;

increased exposure to foreign currency exchange rate risk or currency exchange controls imposed by 
foreign countries;

the risk of import, export and transportation regulations and tariffs on foreign trade and investment, 
including boycotts and embargoes;

taxation and revenue policies or other restrictions, including royalty and tax increases, retroactive tax 
claims and the imposition of unexpected taxes; 

the imposition of, or rapid or unexpected adverse changes in, foreign laws, regulatory requirements or 
trade policies;

restrictions on repatriation of earnings or capital or transfers of funds into or out of foreign countries;

limited protection for intellectual property rights in some jurisdictions;

inability to obtain adequate insurance;

difficulty administering internal controls and legal and compliance practices in countries with different 
cultural norms and business practices;

the possibility of being subjected to the jurisdiction of foreign courts in connection with legal disputes 
and the possible inability to subject foreign persons to the jurisdiction of courts in the United States;

the misinterpretation of local contractual terms, renegotiation or modification of existing long-term 
supply agreements and enforcement of contractual terms in disputes before local courts;

the inability to maintain or enforce legal rights and remedies at a reasonable cost or at all; and

the potential for political unrest, expropriation, nationalization, revolution, war or acts of terrorism in 
countries in which we operate.

In particular, our operations in China are subject to a variety of specific risks, which may adversely affect our 

business, including:

•

•

the recent imposition by the United States of proposed tariffs on wind turbines and certain wind turbine 
components, including wind turbine blades, being imported into the United States;

the deterioration of the diplomatic and political relationships between the United States and China 
resulting from such factors as the opposition of the United States to censorship and other policies of the 
Chinese government, China’s growing trade surpluses with the United States and the introduction by the 
United States of trade restrictions that would impact Chinese imports and any retaliatory measures that 
could ensue;

20

•

•

the uncertainty of the Chinese legal regime generally, and in particular in protecting intellectual 
property and contractual rights, in securing future land use rights, and the recent adoption of new labor, 
environmental and tax laws, the impacts of which are not yet fully understood; and

various restrictions on our ability to repatriate profits from China to other jurisdictions. See “Risk 
Factors—Risks Related to our Business as a Whole—We may have difficulty making distributions and 
repatriating earnings from our Chinese manufacturing operations, which may also occur in some of our 
other locations.”

We also operate in developing markets, which have, in the past, experienced, and may in the future 

experience, social and political unrest. For example, Turkey has experienced problems with domestic terrorist and 
ethnic separatist groups and attempted military coups. The issue of civil rights for Kurdish citizens remains a 
potential source of political instability, which may be exacerbated by continuing instability in the Middle East.

In addition, the locations of our manufacturing facilities in Juárez, Mexico and Matamoros, Mexico are, and 
have been in the past, subject to violence related to drug trafficking, including kidnappings and killings. This could 
negatively impact our ability to hire and retain personnel, especially senior U.S. managers, to continue to work at 
these facilities, or disrupt our operation in other ways, which could materially harm our business.

As we continue to operate our business globally, our success will depend, in part, on our ability to anticipate 

and effectively manage these and other related risks. We may be unsuccessful in developing and implementing 
policies and strategies that will be effective in managing these risks in each country where we do business or 
conduct operations. Our failure to manage these risks successfully could materially harm our business, operating 
results and financial condition.

We may not achieve the long-term growth we anticipate if wind turbine OEMs do not continue to shift from in-
house production of wind blades to outsourced wind blade suppliers and if we do not expand our customer 
relationships and add new customers.

Many wind turbine OEMs rely on in-house production of wind blades for some or all of their wind turbines. 

Our growth strategy depends in large part on the continued expansion of our relationships with our current wind 
blade customers, and the addition of new key customers. All of our customers possess the financial, engineering and 
technical capabilities to produce their own wind blades and many source wind blades from multiple suppliers. Our 
existing customers may not expand their wind energy operations or, if they do, they may not choose us to supply 
them with new or additional quantities of wind blades. Our collaborative dedicated supplier model for the 
manufacture of wind blades is a significant departure from traditional vertically integrated methods. As is typical for 
rapidly evolving industries, customer demand for new business models is highly uncertain. Although we have 
entered into long-term supply agreements with customers that also produce wind blades for their wind turbines in-
house, we may not be able to maintain these customer relationships or enter into similar arrangements with new 
customers that produce wind blades in-house in the future. In addition, although GE Wind historically outsourced all 
of their wind blade production requirements prior to its acquisition of LM, we expect that GE Wind will utilize LM 
for a substantial percentage of its wind blade production in the future. Our business and growth strategies depend in 
large part on the continuation of the trend toward outsourcing manufacturing. If that trend does not continue or we 
are unsuccessful in persuading wind turbine OEMs to shift from in-house production to the outsourcing of their 
wind blade manufacturing, we may not achieve the long-term growth we anticipate and our market share could be 
limited.

A drop in the price of energy sources other than wind energy, or our inability to deliver wind blades that compete 
with the price of other energy sources, may materially harm our business, financial condition and results of 
operations.

We believe that the decision to purchase wind energy is, to a significant degree, driven by the relative cost of 

electricity generated by wind turbines compared to the applicable price of electricity from the utility grid and the 
cost of traditional and other renewable energy sources. Decreases in the prices of electricity from the relevant utility 
grid or from renewable energy sources other than wind energy, such as solar, would harm the market for wind 
energy. In particular, a drop in natural gas prices could lessen the appeal of wind-generated electricity. 

21

Technological advancements or the construction of a significant number of power generation plants, including 
nuclear, coal, natural gas or power plants utilizing other renewable energy technologies, government support for 
other forms of renewable energy or construction of additional electric transmission and distribution lines could 
reduce the price of electricity produced by competing methods, thereby making the purchase of wind energy less 
attractive. For example, in 2017, President Trump signed an executive order that is intended to promote the domestic 
coal industry, which may make the cost of electricity generated from coal more cost competitive. The ability of 
energy conservation technologies, public initiatives and government incentives to reduce electricity consumption or 
support other forms of renewable energy could also lead to a reduction in the price of electricity, which would 
undermine the attractiveness of wind energy and thus wind turbines, and, ultimately wind blades. If prices for 
electricity generated by wind turbines are not competitive, our business, financial condition and results of operations 
may be materially harmed.

If any precision molding and assembly systems needed for our manufacturing process contains a defect or is not 
fabricated and delivered in a timely manner, our ongoing manufacturing operations, business, financial 
condition and results of operation may be materially harmed.

We custom fabricate many of the precision molding and assembly systems used in our facilities. Our 
customers also have the option of using third-party manufacturers to produce their custom tooling. If any piece of 
equipment fails, is determined to produce nonconforming or defective products or is not fabricated and delivered in 
a timely manner, whether produced by us or a third party, our wind blade production could be interrupted and we 
could be subject to contractual penalties, warranty claims, loss of revenues and damage to our customer 
relationships, among other consequences.

The long sales cycle involved in attracting new customers may make the timing of our revenue difficult to predict 
and may cause our operating results to fluctuate.

The complexity, expense and long-term nature of our supply agreements generally require a lengthy customer 

education, evaluation and approval process. It can take us from several months to years to identify and attract new 
customers, if we are successful at all. This long sales cycle for attracting and retaining new customers subjects us to 
a number of significant risks that may materially harm our business, results of operation and financial condition over 
which we have limited control, including fluctuations in our quarterly operating results. In addition, we may incur 
substantial expenses and devote significant management effort to develop potential relationships that do not result in 
agreements or revenue and may prevent us from pursuing other opportunities.

We encounter intense competition for limited customers from other wind blade manufacturers, as well as in-
house production by wind turbine OEMs, which may make it difficult to enter into long-term supply agreements, 
keep existing customers and potentially get new customers.

We face significant competition from other wind blade manufacturers, and this competition may intensify in 

the future. The wind turbine market is characterized by a relatively small number of large OEMs. In addition, a 
significant percentage of wind turbine OEMs, including most of our current customers, produce some of their own 
wind blades in-house. As a result, we compete for business from a limited number of customers that outsource the 
production of wind blades. We also compete with a number of wind blade manufacturers in China, who are growing 
in terms of their technical capability and aspire to expand outside of China. Many of our competitors have more 
experience in the wind energy industry, as well as greater financial, technical or human resources than we do, which 
may limit our ability to compete effectively with them and maintain or improve our market share. Additionally, our 
long-term supply agreements dedicate capacity at our facilities to our customers, which may also limit our ability to 
compete if our facilities cannot accommodate additional capacity. If we are unable to compete effectively for the 
limited number of customers that outsource production of wind blades, our ability to enter into long-term supply 
agreements with potential new and existing customers may be materially harmed.

22

We could be affected by increasing competition from new and existing industry participants and industry 
consolidation.

The markets in which we operate are increasingly competitive and any failure on our part to compete 
effectively on an ongoing basis could materially harm our business, results of operations or financial condition. The 
key factors affecting competition in the wind energy industry are the capacity and quality of products, technology, 
price, the ability to fulfill local market requirements and the scope, cost and location of manufacturing facilities. 

Competition in the wind energy industry has intensified in recent years as a result of a number of factors, 

including international expansion by existing industry participants exploiting new markets, particularly as political 
will around the issues of global warming and the environment become more prominent to the political agenda in 
those new markets. There has also been increasing pressure from Asian manufacturers improving the quality and 
reliability of their technologies, and considering moving out of their local markets and into international cross border 
transactions. Western wind turbine OEMs have now started using Asian manufacturers for a portion of their wind 
blades. Market entry by certain large industrial groups, including those previously unconnected to the wind energy 
market, through acquisitions and license agreements and numerous greenfield establishments in certain markets, also 
poses a competition risk. 

The competitive environment in the wind energy industry may become more challenging in the years ahead, 

particularly in the event of greater consolidation in the industry, leading to greater market power and “economies of 
scale” by such market players which translate into being able to offer greater “cost of energy” savings to wind power 
plant customers. For example, GE completed its acquisition of LM in 2017 and also acquired Alstom S.A.’s power 
business in 2015; Nordex completed its acquisition of Acciona in 2016 and Gamesa merged with Siemens’ Wind 
Power in 2017. These transactions or further consolidation in the wind energy industry may have an adverse impact 
on our business in the future, including, without limitation, reduced demand for our products and services, product 
innovation, changes in pricing and similar factors, including any competitor’s attempt to duplicate our collaborative 
dedicated supplier model. Such events could materially harm our business, results of operations, financial condition 
or prospects.

Significant increases in the prices of raw materials or components that cannot be reflected in the price of our 
products could negatively affect our operating margins.

The prices of our raw materials and components are subject to price fluctuations resulting from volatility of 
supply and demand in world markets. Under our long-term supply agreements, our customers generally commit to 
purchase minimum annual volumes and prices for wind blades are generally set as of the date of our supply 
agreements and adjusted quarterly, for the cost of raw material and our operating expenses in certain cases. As a 
result, the competitive nature of the wind blade market and our long-term supply agreements with our customers 
may delay or prevent us from passing cost increases in raw materials and components on to our customers. 
Significant increases in the price of raw materials or components used in our manufactured wind blades that cannot 
be reflected in the price of our products, could negatively affect our operating margins and materially harm our 
business, operating results or financial condition.

GE’s acquisition of LM Wind Power, our largest competitor, may materially harm our business, financial 
condition and results of operations and may cause the price of our common stock to decline.

In 2017, GE completed its acquisition of LM Wind Power, our largest competitor. By the end of 2016, we had 
entered into five supply agreements with GE Wind providing for the supply of wind blades from our Iowa, Mexico, 
Turkey and our Taicang Port, China facilities. In 2016, we entered into (i) an amended and restated supply 
agreement for the continued supply of wind blades from our Iowa facility through December 31, 2020, (ii)  an 
amendment to our existing supply agreement for the continued supply of wind blades from our original Juárez, 
Mexico facility through December 31, 2020 and (iii) a new supply agreement with GE Wind for the supply of 
incremental wind blades from our second manufacturing facility in Juárez, Mexico through December 31, 2020. GE 
Wind elected not to renew or extend the Turkey and Taicang Port, China supply agreements, which both expired on 
December 31, 2017. We expect that GE Wind will utilize LM for a substantial percentage of its wind blade 
production in the future. As such, GE Wind may not continue to purchase wind blades from us at similar volumes or 
on as favorable terms in the future. In August 2018, GE Wind did agree to extend our existing supply agreement in 

23

one of our Mexico plants by two years to 2022 and increased the number of wind blade manufacturing lines in that 
facility from three to five. In addition, GE Wind has agreed to transition to a larger blade model in our Newton, 
Iowa plant in early 2019 and to eliminate its option to terminate their supply agreement at this location prior to its 
December 2020 expiration. Unless otherwise terminated or renewed, our supply agreements with GE Wind are in 
effect until the end of 2020 for our Iowa and one of our Mexico facilities and until the end of 2022 for our other 
Mexico facility. GE Wind may terminate the Mexico supply agreements with no advance notice and paying us 
termination fees as set forth in the applicable agreement. In addition, either party may terminate these supply 
agreements upon a material breach by the other party which goes uncured for 30 days after written notice has been 
provided. If GE Wind elects to utilize LM or another supplier for more of its wind blade production, reduce the 
volumes of wind blades it purchases from us or terminates any of our supply agreements, it may materially harm our 
business, financial condition and results of operations.

Certain of our long-term supply agreements are highly dependent upon a limited number of suppliers of raw 
materials.

Our ability to perform under certain of our long-term supply agreements is currently, and may continue to be 
in the future, highly dependent on a limited number of suppliers of raw materials. For instance, our agreements with 
certain customers require us or our customers to purchase raw materials from a single supplier unless additional 
suppliers are evaluated and found to satisfy the requirements set out in those agreements. In 2015, for example, our 
ability to supply wind blades to one of our customers was constrained because our customer, who under our 
agreement was required to procure a sufficient supply of a specific type of material, was unable to procure the 
material from a single source supplier. Should any of these suppliers of raw materials experience production delays 
or shortages, have their operations interrupted or otherwise cease or curtail their operations, this may disrupt or 
materially harm our business, operating results and financial condition.

Significant increases in the cost of transporting the wind blades we manufacture could negatively affect the 
demand for our products.

A significant portion of our customers’ costs relate to the costs necessary to transport the wind blades we 

manufacture to their customers’ wind farms. Demand for our products could be negatively affected if the costs our 
customers bear to transport the wind blades we manufacture materially increase.

The nature of our manufacturing processes and unanticipated changes to those processes could significantly 
reduce our manufacturing yields and product reliability, which could materially harm our business, operating 
results and financial condition.

The manufacturing of our wind blades involves highly complex and precise processes which may be 
dictated by our customers’ requests requiring production in highly controlled environments. Changes in our 
manufacturing processes or that are required by our customers could affect product reliability. Furthermore, many 
of our processes are manual to facilitate production flexibility and compliance with customer requirements. A 
manually dependent manufacturing process can limit capacity and increase production costs. In some cases, 
existing manufacturing techniques may be insufficient to achieve the volume or cost targets of our customers. For 
example, our manufacturing processes may at times require a quantity of raw materials greater than the quantity 
for which we have contracted, making it difficult for us to achieve the targeted cost levels negotiated with our 
customers. In order to achieve targeted volume and cost levels, we may need to increase the quantity of raw 
materials for which we contract or develop new manufacturing processes and techniques. While we continue to 
devote substantial efforts to the improvement of our manufacturing techniques and processes, we may not achieve 
manufacturing volumes and cost levels in our manufacturing activities that will fully satisfy customer demands, 
which could materially harm our business, operating results and financial condition.

Our reserves for warranty expenses might not be sufficient to cover all future costs.

We provide warranties for all of the wind blades and precision molding and assembly systems we produce, 

including parts and labor, for periods that typically range from two to five years depending on the product sold. If a 
wind blade is found to be defective during the warranty period as a result of a defect in workmanship or materials, or 
if we are required to cover remediation expenses or other potential remedies, in addition to our regular warranty 

24

coverage we may need to repair or replace the wind blade (which could include significant transportation, 
installation and erection costs) at our sole expense. Our estimate of warranty expense requires us to make 
assumptions about matters that are highly uncertain, including future rates of product failure, repair costs, shipping 
and handling and de-installation and re-installation costs at customers’ sites. Our assumptions could be materially 
different from the actual performance of our products and these remediation expenses in the future. The expenses 
associated with wind blade repair and remediation activities can be substantial and may include changes to our 
manufacturing processes. If our estimates prove materially incorrect, we could incur warranty expenses that exceed 
our reserves and be required to make material unplanned cash expenditures, which could materially harm our 
business, operating results and financial condition.

We may not be able to meet our customers’ future wind blade supply demands, which may hinder our customer 
relationships and reputation.

Historically, our existing customers’ demand and MW capacity goals have mirrored the anticipated growth of 

the wind energy industry. Given the importance of wind energy capture, turbine reliability and cost to power 
producers, the size, quality and performance of wind blades have become highly strategic to our OEM customers. If 
we are unable to maintain future manufacturing capacity at levels that meet our customers’ increasing demands, 
including with respect to volume, technical specifications, or commercial terms, our existing customers may seek 
relationships with, or give priority to, other wind blade manufacturers or may use or develop their own internal 
manufacturing capabilities to meet their increased demand, which could materially harm our business, operating 
results and financial condition. In addition, our reputation could be materially harmed if we are unable to satisfy the 
requirements of our customers.

We rely on our research and development efforts to remain competitive, and we may fail to develop on a timely 
basis new wind blade manufacturing technologies that are commercially attractive or permit us to keep up with 
customer demands.

The market for wind blades is subject to evolving customer needs and expectations. Our research and 
development is invested in developing faster and more efficient manufacturing processes in order to build the new 
wind blades designed by our customers that more effectively capture wind energy and are adaptable to new growth 
segments of the wind energy market. Research and development activities are inherently uncertain and the results of 
our in-house research and development may not be successful. In addition, our competition may adopt more 
advanced technologies or develop wind blades that are more effective or commercially attractive. We believe that 
our future success will depend in large part upon our ability to be at the forefront of technological innovation in the 
wind energy industry and to rapidly and cost-effectively adapt our wind blade manufacturing processes to keep pace 
with changing technologies, new wind blade design and changing customer needs. If we are unable to do so, our 
business, operating results, financial condition and reputation could be materially harmed.

We depend on third parties for certain construction, maintenance, engineering, transportation, warehousing and 
logistics services, and failures of those third parties to perform their obligations may in turn impede our ability to 
perform our obligations.

We contract with third parties for certain services relating to the design, construction and maintenance of 
various components of our production facilities and other systems. If these third parties fail to comply with their 
obligations:

•

•

•

•

we may experience delays in the completion of new facilities or expansion of existing facilities;

the facilities may not operate as intended;

we may be required to recognize impairment charges; or

we could experience production delays, which could cause us to miss our production capacity targets 
and breach our long-term supply agreements, which could damage our relationships with our customers 
and subject us to contractual penalties and contract termination.

25

Any of these events could have a material adverse effect on our business, operating results or financial 
condition. Our customers also contract with third parties for the transportation of the products we manufacture. In 
particular, a significant portion of the goods we manufacture are transported to different countries, which requires 
customized shipping cradles, sophisticated warehousing, logistics and other resources. If our customers fail to 
contract with third parties for certain construction, maintenance, engineering, transportation, warehousing and 
logistics services, or there are any disruptions, delays or failures in these services, this could have a material adverse 
effect on our business, operating results or financial condition.

Various legislation, regulations and incentives that are expected to support the growth of wind energy in the 
United States and around the world may not be extended or may be discontinued, phased out or changed, or may 
not be successfully implemented, which could materially harm wind energy programs and materially decrease 
demand for the wind blades we manufacture.

The U.S. wind energy industry is dependent in part upon governmental support through certain incentives 
including federal tax incentives and RPS programs and may not be economically viable absent such incentives. 
Government-sponsored tax incentive programs including the PTC, and to a lesser extent, the Investment Tax Credit, 
are expected to support the U.S. growth of wind energy. The PTC provided the owner of a wind turbine placed in 
operation before January 1, 2015 with a ten year credit against its U.S. federal income tax obligations based on the 
amount of electricity generated by the wind turbine.

Although the PTC was extended in December 2015 for wind power projects through December 31, 2019, as 

currently contemplated, the PTC rate is being phased out over the term of the PTC extension. Specifically, as 
currently contemplated, the PTC will remain at the same rate in effect at the end of 2014 for wind power projects 
that commence construction by the end of 2016, and thereafter will be reduced by 20% per year in 2017, 2018 and 
2019, respectively. The Tax Cuts and Jobs Act (Tax Reform) legislation preserved the PTC, which was a positive 
outcome for the wind industry. However, while the tax equity market continues to function, Tax Reform has created 
some near-term uncertainty around the amount of available tax equity financing as financial institutions fully 
evaluate the impacts of the new tax law.

In 2015, the EPA enacted the Clean Power Plan, which is also intended to promote the growth of renewable 
energy. However, in 2016, the U. S. Supreme Court issued a stay of the EPA’s implementation of the Clean Power 
Plan until the D.C. Circuit of the U.S. Court of Appeals reviews the merits of multiple lawsuits challenging the 
legality of the Clean Power Plan. If the Clean Power Plan is not successfully implemented, demand for the wind 
blades we manufacture may be materially decreased. In addition, in 2017, President Trump signed an executive 
order that requires, among other things, that the EPA review the Clean Power Plan and publish a rule to either 
suspend, revise or rescind it.

In addition, many state governments have adopted measures designed to promote wind energy. For example, 

according to the American Wind Energy Association (AWEA), at the state level, as of December 31, 2018, 29 
states, as well as the District of Columbia and Puerto Rico, have implemented RPS programs that mandate that a 
specific percentage of electricity sales in a state come from renewable energy within a specified period. However, 
some RPS programs have been challenged and all of them may not continue going forward. These programs have 
spurred significant growth in the wind energy industry in the United States and a corresponding increase in the 
demand for our manufactured wind blades. However, although the U.S. government and several state governments 
have adopted these various programs that are expected to help drive the growth of wind energy, they may approve 
new or additional programs that might hinder the wind energy industry and therefore negatively impact our business, 
operating results or financial condition. 

China is implementing its 13th 5-Year Plan with a goal of 15% energy from non-fossil fuel sources and 
targeting 210 GWs of grid-connected wind capacity by 2020, according to its National Development and Reform 
Commission, and employs preferential feed-in tariff schemes, in addition to local tax-based incentives. Mexico has 
established strict targets, aiming for 35% renewable energy by 2024 and 50% by 2050, according to WoodMac, 
which it is facilitating through tax incentives. Large European Union members have renewable energy targets for 
2020 of between 13% and 49% of all energy use derived from renewable energy sources, according to WoodMac. 
Turkey enacted Law No. 5346 in 2005 to promote renewable-based electricity generation within its domestic 
electricity market by introducing tariffs and purchase obligations for distribution companies requiring purchases 

26

from certified renewable energy producers. The World Bank also provided to Turkey an aggregate of $600 million 
of loan proceeds to encourage investors to construct generation plants with renewable energy resources. These 
programs have spurred significant growth in the wind energy industry internationally and a corresponding increase 
in the demand for our manufactured wind blades. However, although foreign governments have adopted various 
programs that are expected to drive the growth of wind energy, they may approve new or additional programs going 
forward that might hinder the wind energy industry and therefore negatively impact our business as a result. For 
example, foreign governments may decide to reduce or eliminate these economic incentives for political, financial or 
other reasons. They may also favor other forms of energy, including current and new sources of energy such as 
solar, nuclear and hydropower. Foreign governments may also cancel or delay scheduled tender offers or auctions 
for wind energy projects.  For example, the Mexican government recently canceled the country’s fourth energy 
tender which was in the final stages to contract a minimum 5% of national power by 2021. 

Because of the long lead times necessary to develop wind energy projects, any uncertainty or delay in 
adopting, extending or renewing these incentives beyond their current or future expiration dates could negatively 
impact potential wind energy installations and result in industry volatility. There can be no assurance that the PTC, 
the Clean Power Plan, tender offers, auctions or other governmental programs or subsidies for renewable energy will 
remain in effect in their present form or at all, and the elimination, reduction, or modification of these programs or 
subsidies could materially harm wind energy programs in the United States and international markets and materially 
decrease demand for the wind blades we manufacture and, in turn, materially harm our business, operating results 
and financial condition.

We may not be able to obtain, or agree on acceptable terms and conditions for, government tax credits, grants, 
loans and other incentives for which we have in the past applied or may in the future apply, which may materially 
harm our business, operating results and financial condition.

We have in the past and may in the future rely, in part, on tax credits, grants, loans and other incentives under 

U.S. and foreign governmental programs to support the construction of new plants and expansion of existing 
manufacturing facilities. We may not be successful in obtaining these tax credits, grants, loans and other incentives, 
and the tax and other incentives that have already been approved may not be continued in the future. Our ability to 
obtain funds or incentives from government sources is subject to the availability of funds under applicable 
governmental programs and approval of our applications to participate in these programs. The application process 
for these funds and other incentives is and will be highly competitive. We may not be able to satisfy the 
requirements and milestones imposed by the granting authority as conditions to receipt of the funds or other 
incentives, the timing of the receipt of the funds may not meet our needs, and, even if obtained, we may be unable to 
successfully execute on our business plan. Moreover, not all of the terms and conditions associated with these 
incentive funds have been disclosed to us, and once disclosed, there may be terms and conditions with which we are 
unable to comply or that are commercially unacceptable to us. Further, participation in certain programs may require 
us to notify the federal government of certain intellectual property we develop and comply with applicable 
regulations in order to protect our interests in that intellectual property. In addition, these federal governmental 
programs may require us to spend a portion of our own funds for every incentive dollar we receive or are permitted 
to borrow from the government and may impose time limits during which we must use the funds awarded to us that 
we may be unable to achieve. If we are unable to obtain or comply with the terms of these tax credits, grants, loans 
or other incentives, our business, operating results and financial condition may be harmed.

Adverse weather conditions could impact the wind energy industry in some regions and could materially harm 
our business, operating results and financial condition.

Our business may be subject to fluctuations in sales volumes due to adverse weather conditions that could 

delay the erection of wind turbines, the installation of wind blades and the ability of wind turbines to generate 
electricity efficiently. Moreover, any remediation efforts we could be required to undertake pursuant to wind blade 
warranties could be delayed or otherwise adversely impacted by poor weather. Although our customer base and 
manufacturing footprint is geographically diversified, enduring weather patterns or seasonal variations may impact 
the expansion of the wind energy industry in certain regions. A resulting reduction or delay in demand for the wind 
blades we manufacture for our customers could materially harm our business, operating results and financial 
condition.

27

Our long-term growth and success is dependent upon retaining our senior management and attracting and 
retaining qualified personnel.

Our growth and success depends to a significant extent on our ability to attract and retain highly qualified 

research and development, management, manufacturing, marketing and other key personnel including engineers in 
our various locations. In addition, we rely heavily on our management team, including Steven C. Lockard, our Chief 
Executive Officer; Joseph G. Kishkill, our Chief Commercial Officer; William E. Siwek, our Chief Financial 
Officer; and other senior management. The inability to recruit and retain key personnel or the unexpected loss of key 
personnel may materially harm our business, operating results and financial condition. Hiring those persons may be 
especially difficult because of the specialized nature of our business and our international operations. If we cannot 
attract and retain qualified personnel, or if we lose the services of Messrs. Lockard, Kishkill or Siwek, other key 
members of senior management or other key personnel, our ability to successfully execute our business plan, market 
and develop our products and serve our customers could be materially and adversely affected. In addition, because 
of our reliance on our management team, our future success depends, in part, on its ability to identify and develop 
talent to succeed its senior management. The retention of key personnel and appropriate senior management 
succession planning will continue to be critical to the successful implementation of our future strategies.

Risks Related to our Transportation Business 

Our efforts to expand our transportation business and enter into other strategic markets may not be successful.

While our primary focus has been to manufacture composite wind blades, our strategy is to expand our 
transportation business and to enter into other strategic markets. In 2018, we expanded our relationship with Proterra 
and began supplying bus bodies from a new manufacturing facility in Newton, Iowa in addition to our 
manufacturing facility in Warren, Rhode Island. We experienced start up challenges in connection with the supply 
of bus bodies to Proterra from our Newton, Iowa manufacturing facility.  The expansion of our transportation 
business and our entry into other strategic markets will require improved execution in terms of our start up activity 
and ongoing manufacturing performance as well as significant levels of investment. There can be no assurance that 
our transportation business or other strategic markets will develop as anticipated or that we will have success in any 
such markets, and if we do not, we may be unable to recover our investment, which could adversely impact our 
business, financial condition and results of operations, including potentially impairing the value of our goodwill.

We may incur material losses and costs as a result of product liability and warranty claims, litigation and other 
disputes and claims. 

We are exposed to warranty and product liability claims if our transportation products fail to perform as 
expected. We may in the future be required to participate in a recall of these products or the vehicles incorporating 
our products. If public safety concerns are raised, we may have to participate in a recall even if our products are 
ultimately found not to be defective. Vehicle manufacturers have experienced increasing recall campaigns in recent 
years. Our customers may look to us for contribution when faced with recalls and product liability claims. If our 
customers demand higher warranty-related cost recoveries, or if our transportation products fail to perform as 
expected, our business, financial condition and results of operations could materially suffer. 

We may also be exposed to product liability claims, warranty claims and damage to our reputation if our 
transportation products actually or allegedly fail to perform as expected or the use of our products results, or is 
alleged to result, in bodily injury or property damage. Recalls may also cause us to lose additional business from our 
customers. Material product defect issues may subject us to recalls of those products and restrictions on bidding on 
new customer programs. 

Risks Related to Our Business as a Whole

We may not be able to manage our future growth effectively, which may materially harm our business, operating 
results and financial condition.

We expect to continue to expand our business significantly to meet our current and expected future contractual 

obligations and to satisfy anticipated increased demand for our products. To manage our anticipated expansion, we 
believe we must scale our internal infrastructure, including establishing additional facilities, improve our operational 
systems and procedures and manufacturing capabilities, continue to enhance our compliance and quality assurance 
systems, train and manage our growing employee base, and retain and add to our current executives and 

28

management personnel. Rapid expansion of our operations could place a significant strain on our senior 
management team, support teams, manufacturing lines, information technology platforms and other resources. 
Difficulties in effectively managing the budgeting, forecasting and other process control issues presented by any 
rapid expansion could materially harm our business, prospects, results of operations or financial condition. Our 
inability to implement operational improvements, generate and sustain increased revenue and manage and control 
our cost of goods sold and operating expenses could impede our future growth and materially harm our business, 
operating results and financial condition.

Our financial position, revenue, operating results and profitability are difficult to predict and may vary from 
quarter to quarter, which could cause our share price to decline significantly.

Our quarterly revenue, operating results and profitability have varied in the past and are likely to vary 
significantly from quarter to quarter in the future. For example, our quarterly results have ranged from an operating 
profit of $21.0 million for the three months ended September 30, 2017 to an operating loss of $3.6 million for the 
three months ended December 31, 2018. The factors that are likely to cause these variations include:

•

•

•

•

•

•

•

•

•

•

•

•

•

operating and startup costs of new manufacturing facilities;

wind blade model transitions;

differing quantities of wind blade production;

unanticipated contract or project delays or terminations;

changes in the costs of raw materials or disruptions in raw material supply;

scrap of defective products;

warranty expense;

availability of qualified personnel;

employee wage levels;

costs incurred in the expansion of our existing manufacturing capacity;

volume reduction requests from our customers pursuant to our customer agreements; 

general economic conditions; and 

the complexity of the financial assumptions we must use for forecasting our revenue, profitability and 
operating results under ASU 2014-09, Revenue from Contracts with Customers (Topic 606), the 
recently enacted new accounting standard for revenue recognition and the impact that unanticipated 
blade transitions have on those estimates.  

As a result, our revenue, operating results and profitability for a particular period are difficult to predict and 

may decline in comparison to corresponding prior periods regardless of the strength of our business. It is also 
possible that in some future periods our revenue, operating results and profitability may not meet the expectations of 
securities analysts or investors. If this occurs, the trading price of our common stock could fall substantially, either 
suddenly or over time, and our business, operating results and financial condition would be materially harmed.

The fluctuation of foreign currency exchange rates could materially harm our financial results.

Since we conduct a significant portion of our operations internationally, our business is subject to foreign 
currency risks, including currency exchange rate fluctuations. The exchange rates are affected by, among other 
things, changes in political and economic conditions. For example, an increase in our Turkey sales and operations 
will result in a larger portion of our net sales and expenditures being denominated in the Euro and Turkish Lira. 
Significant fluctuations in the exchange rate between the Turkish Lira and the U.S. dollar, the Turkish Lira and the 
Euro or the Euro and the U.S. dollar may adversely affect our revenue, expenses, as well as the value of our assets 
and liabilities. Similarly, an increase in our sales within China may result in a larger portion of our net sales and 
expenditures being denominated in Chinese Renminbi. The Chinese government controls the procedures by which 

29

the Chinese Renminbi is converted into other currencies, and conversion of the Chinese Renminbi generally requires 
government consent. As a result, the Chinese Renminbi may not be freely convertible into other currencies at all 
times. If the Chinese government institutes changes in currency conversion procedures, or imposes restrictions on 
currency conversion, those actions may materially harm our business, liquidity, financial condition and operating 
results. In addition, significant fluctuations in the exchange rate between the Chinese Renminbi and U.S. dollars 
may adversely affect our revenues, expenses as well as the value of our assets and liabilities. However, in Mexico, 
since all of our net sales and some of our expenditures are denominated in U.S. dollars, an increase in our Mexico 
sales and operations will result in a larger portion of our cost of goods sold being denominated in the Mexican Peso.  
Significant fluctuations in the exchange rate between the Mexican Peso and the U.S. dollar may adversely affect our 
expenses, as well as the value of our assets and liabilities. To the extent our future revenues and expenses are 
generated outside of the United States in currencies other than the U.S. dollar, including the Euro, the Turkish Lira, 
the Chinese Renminbi, Mexican Peso or India Rupee, among others, we will be subject to increased risks relating to 
foreign currency exchange rate fluctuations which could materially harm our business, financial condition and 
operating results.

Our manufacturing operations and future growth are dependent upon the availability of capital, which may be 
insufficient to support our capital expenditures.

Our current wind blade manufacturing activities and future growth will require substantial capital investment. 

For the years ended December 31, 2018 and 2017, our capital expenditures were $74.7 million and $51.0 million, 
respectively, including assets acquired under capital lease in 2018 and 2017 of $22.0 million and $6.2 million, 
respectively. We have recently entered into lease agreements with third parties to lease new manufacturing facilities 
in China, India and Mexico. Major projects expected to be undertaken include purchasing equipment for our new 
manufacturing facilities in Yangzhou, China, Chennai, India, Matamoros, Mexico and Juarez, Mexico, and the 
expansion of our Mexico and Turkey facilities as well as costs to enhance our information technology systems. Our 
ability to grow our business is predicated upon us making significant additional capital investments to expand our 
existing manufacturing facilities and build and operate new manufacturing facilities in existing and new markets. 
We generally estimate that the startup of a new six-line manufacturing facility requires cash for net operating 
expenses and working capital of between $20 million to $25 million and additional capital expenditures primarily 
for machinery and equipment of between $30 million to $35 million. In addition, we estimate our annual 
maintenance capital expenditures to be between $1.0 million to $2.0 million per facility. We may not have the 
capital to undertake these capital investments. In addition, our capital expenditures may be significantly higher if our 
estimates of future capital investments are incorrect and may increase substantially if we are required to undertake 
actions to comply with new regulatory requirements or compete with new technologies. The cost of some projects 
may also be affected by foreign exchange rates if any raw materials or other goods must be paid for in foreign 
currency. We cannot assure you that we will be able to raise funds on favorable terms, if at all, or that future 
financings would not be dilutive to holders of our capital stock. We also cannot assure you that completed capital 
expenditures will yield the anticipated results. If we raise additional funds by obtaining loans from third parties, the 
terms of those financing arrangements may include negative covenants, or other restrictions on our business that 
could impair our operational flexibility, and would require us to fund additional interest expense. If we are unable to 
obtain sufficient capital at a reasonable cost or at all, we may not be able to expand production sufficiently to take 
advantage of changes in the marketplace or may be required to delay, reduce or eliminate some or all of our current 
operations, which could materially harm our business, operating results and financial condition.

As a U.S. corporation with international operations, we are subject to the U.S. Foreign Corrupt Practices Act of 
1977, which could impact our ability to compete in certain jurisdictions.

As a U.S. corporation, we are subject to the FCPA, which generally prohibits U.S. companies and their 
intermediaries from making improper payments to foreign officials for the purpose of obtaining or keeping business. 
We have or will soon have manufacturing facilities in China, Mexico, Turkey and India, countries with a fairly high 
risk of corruption. Those facilities are subject to routine government oversight. In addition, a number of our raw 
materials and components suppliers are state-owned in China. Moreover, due to our need to import raw materials 
across international borders, we also routinely have interactions, directly or indirectly, with customs officials. In 
many foreign countries, under local custom, businesses engage in practices that may be prohibited by the FCPA or 
other similar laws and regulations. Additionally, we continue to hire employees around the world as we continue to 
expand. Although we have implemented certain procedures and controls designed to ensure compliance with the 

30

FCPA and similar laws, there can be no guarantee that all of our employees and agents, as well as those companies 
to which we outsource certain of our business operations, have not taken and will not take actions that violate our 
policies and the FCPA, which could subject us to fines, penalties, disgorgement, and loss of business, harm our 
reputation and impact our ability to compete in certain jurisdictions. In addition, these laws are complex and far-
reaching in nature, and, as a result, we may be required in the future to alter one or more of our practices to be in 
compliance with these laws or any changes in these laws or the interpretation thereof. Moreover, our competitors 
may not be subject to the FCPA or comparable legislation, which could provide them with a competitive advantage 
in some jurisdictions.

We may have difficulty making distributions and repatriating earnings from our Chinese manufacturing 
operations, which may also occur in some of our other locations.

A material portion of our business is conducted in China. As of December 31, 2018, our China operations had 
unrestricted cash of $28.9 million, most of which will be used to fund our future operations in China. 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 contracts 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 the People’s Republic of China, including retained earnings as 
determined under Chinese-statutory accounting requirements. Until 50% ($21.6 million) of registered capital is 
contributed to a surplus reserve, our Chinese 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, we can pay 
dividends equal to 100% of after-tax profit assuming other conditions are met. At December 31, 2018, the amount of 
the surplus reserve fund was $6.5 million. Any inability to make distributions, repatriate earnings or otherwise 
access funds from our manufacturing operations in China, if and when needed for use outside of China, could 
materially harm our liquidity and our business. 

Effective internal controls are necessary for us to provide reliable financial reports and effectively address fraud 
risks.

We maintain a system of internal controls to provide reasonable assurance regarding the reliability of financial 

reporting and the preparation of financial statements for external purposes in accordance with U.S. generally 
accepted accounting principles (GAAP). The process of designing and implementing effective internal controls is a 
continuous effort that requires us to anticipate and react to changes in our business and the economic and regulatory 
environments and to expend significant resources to establish and maintain a system of internal controls that will be 
adequate to satisfy the reporting obligations of a public company. The effectiveness of our internal controls depends 
in part on the cooperation of senior managers worldwide. 

Any system of controls, however well designed and operated, can provide only reasonable, and not absolute, 
assurance that the objectives of the system are met. Any failure to maintain that system, or consequent inability to 
produce accurate financial statements on a timely basis, could increase our operating costs and harm our business, 
and lead to our becoming subject to litigation, sanctions or investigations by The NASDAQ Global Market 
(NASDAQ), the SEC or other regulatory governmental agencies and bodies. Furthermore, investors’ perceptions 
that our internal controls are inadequate or that we are unable to produce accurate financial statements on a timely 
basis may harm our stock price.

We have in the past experienced material weaknesses. While we have successfully remediated those material 

weaknesses, we could experience control deficiencies in the future or identify areas requiring improvement in our 
internal control over financial reporting.

31

The state of financial markets and the economy may materially harm our sources of liquidity and capital.

There has been significant recent turmoil and volatility in worldwide financial markets. These conditions have 

resulted in a disruption in the liquidity of financial markets, and could directly impact us to the extent we need to 
access capital markets to raise funds to support our business and overall liquidity position. This situation could 
affect the cost of such funds or our ability to raise such funds. If we were unable to access any of these funding 
sources when needed, it could materially harm our business, operating results and financial condition.

Our ability to use our net operating loss carry forwards may be subject to limitation and may result in increased 
future tax liability.

Sections 382 and 383 of the Internal Revenue Code of 1986, as amended (the Code), contain rules that limit 
the ability of a company that undergoes an “ownership change” to utilize its net operating loss and tax credit carry 
forwards and certain built-in losses recognized in years after the “ownership change”. An “ownership change” is 
generally defined as any change in ownership of more than 50% of a corporation’s stock over a rolling three-year 
period by stockholders that own (directly or indirectly) 5% or more of the stock of a corporation, or arising from a 
new issuance of stock by a corporation. If an ownership change occurs, Section 382 generally imposes an annual 
limitation on the use of pre-ownership change net operating losses (NOLs), credits and certain other tax attributes to 
offset taxable income earned after the ownership change. The annual limitation is equal to the product of the 
applicable long-term tax exempt rate and the value of our common stock immediately before the ownership change. 
This annual limitation may be adjusted to reflect any unused annual limitation for prior years and certain recognized 
built-in gains and losses for the year. In addition, Section 383 generally limits the amount of tax liability in any post-
ownership change year that can be reduced by pre-ownership change tax credit carryforwards. This could result in 
increased U.S. federal income tax liability for us if we generate taxable income in a future period. Limitations on the 
use of NOLs and other tax attributes could also increase our state tax liability. The use of our tax attributes will also 
be limited to the extent that we do not generate positive taxable income in future tax periods. As a result of these 
limitations, we may be unable to offset future taxable income (if any) with losses, or our tax liability with credits, 
before such losses and credits expire. Accordingly, these limitations may increase our federal income tax liability.

We experienced an “ownership change” in June 2018, and it remains possible that future transactions may 

cause us to undergo one or more ownership changes. As of December 31, 2018, we have U.S. federal NOLs of 
approximately $25.8 million and state NOLs of approximately $118.5 million. The pre-ownership change NOLs 
existing at the date of change of $47.7 million are subject to annual limitation.  We do not believe that the Section 
382 and 383 annual limitation will materially impact our ability to utilize the tax attributes that existed as of the date 
of the ownership change.

We have U.S. federal and state NOLs. In general, NOLs in one country cannot be used to offset income in any 

other country and NOLs in one state cannot be used to offset income in any other state. Accordingly, we may be 
subject to tax in certain jurisdictions even if we have unused NOLs in other jurisdictions. Also, each jurisdiction in 
which we operate may have its own limitations on our ability to utilize NOLs or tax credit carryovers generated in 
that jurisdiction. These limitations may increase our federal, state, and/or foreign income tax liability.

Comprehensive tax reform legislation could adversely affect our business, operating results and financial 
condition.               

On December 22, 2017, President Trump signed into law Tax Reform, 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 on 
certain accumulated earnings and profits of foreign corporate subsidiaries (the 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, net operating loss deduction limitations, a tax on global intangible low-taxed income (GILTI) earned by 
foreign corporate subsidiaries, a base erosion anti-abuse tax (BEAT), and a deduction for foreign-derived intangible 
income (FDII). 

32

At 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 U.S. federal income tax 
expense due to the impact of foreign tax credits. In addition, the provisional net tax expense, which was estimated to 
be approximately $0.1 million, primarily attributable to the reduction in the federal tax rate, was unchanged. In 
addition, we have made a policy election to account for any impacts of GILTI tax in the period in which it is 
incurred.  

Our current revolving credit facility with JPMorgan Chase Bank, N.A. Wells Fargo Bank, N.A., Capital One, 
N.A. and Bank of America N.A. contains, and any future loan agreements we may enter into may contain, 
operating and financial covenants that may restrict our business and financing activities.

We have a $150.0 million revolving credit facility (the Credit Facility) with JPMorgan Chase Bank, N.A. 
Wells Fargo Bank, N.A., Capital One, N.A. and Bank of America N.A., consisting of a $125.0 million revolving 
credit facility and a $25.0 million letter of credit sub-facility. As of December 31, 2018, the aggregate outstanding 
balance under the Credit Facility was $90.4 million. The Credit Facility is secured by substantially all of our assets. 
In addition, from time to time, we enter into various loan, working capital and accounts receivable financing 
facilities to finance the construction and ongoing operations of our advanced manufacturing facilities and other 
capital expenditures. The Credit Facility contains various financial covenants and restrictions on our and our 
operating subsidiaries’ excess cash flows and ability to make capital expenditures, incur additional indebtedness and 
pay dividends or make distributions on, or repurchase, our stock. The operating and financial restrictions and 
covenants of the Credit Facility, as well as our other existing and any future financing agreements that we may enter 
into, may restrict our ability to finance our operations, engage in business activities or expand or fully pursue our 
business strategies. Our ability to comply with these covenants may be affected by events beyond our control, and 
we may not be able to maintain appropriate minimum leverage ratio and fixed charge coverage ratio requirements in 
the future. A breach of any of these covenants could result in a default under the applicable loan facility, which 
could cause all of the outstanding indebtedness under such facility to become immediately due and payable by us 
and/or enable the lender to terminate all commitments to extend further credit. In addition, if we were unable to 
repay the outstanding indebtedness upon a default, our lenders could proceed against the assets pledged as collateral 
to secure that indebtedness.

Our indebtedness may adversely affect our business, results of operations and financial condition.

Our indebtedness could adversely affect our business, results of operations and financial condition by, among 

other things:

•

•

•

•

•

•

requiring us to dedicate a substantial portion of our cash flow from operations to pay principal and 
interest on our debt, which would reduce the availability of our cash flow to fund working capital, 
capital expenditures, acquisitions, execution of our growth strategy and other general corporate 
purposes;

limiting our ability to borrow additional amounts to fund debt service requirements, working capital, 
capital expenditures, acquisitions, execution of our growth strategy and other general corporate 
purposes;

making us more vulnerable to adverse changes in general economic, industry and regulatory conditions 
and in our business by limiting our flexibility in planning for, and making it more difficult to react 
quickly to, changing conditions;

placing us at a competitive disadvantage compared with those of our competitors that have less debt and 
lower debt service requirements;

making us more vulnerable to increases in interest rates since some of our indebtedness is subject to 
variable rates of interest; and

making it more difficult for us to satisfy our financial obligations.

33

In addition, we may not be able to generate sufficient cash flow from our operations to repay our outstanding 

indebtedness when it becomes due and to meet our other cash needs or to comply with the financial covenants set forth 
therein. If we are not able to pay our debts as they become due, we could be in default of the Credit Facility or other 
indebtedness. We might also be required to pursue one or more alternative strategies to repay indebtedness, such as 
selling assets, refinancing or restructuring our indebtedness or selling additional debt or equity securities. We may not 
be able to refinance our debt or sell additional debt or equity securities or our assets on favorable terms, if at all, and if 
we must sell assets, it may negatively affect our ability to generate revenues.

Much of our intellectual property consists of trade secrets and know-how that is very difficult to protect. If we 
experience loss of protection for our trade secrets or know-how, our business would be substantially harmed.

We have a variety of intellectual property rights, including patents, trademarks and copyrights, but much of 

our most important intellectual property rights consists of trade secrets and know-how and effective intellectual 
property protection may be unavailable, limited or outside the scope of the intellectual property rights we pursue in 
the United States and in foreign countries such as China where we operate. Although we strive to protect our 
intellectual property rights, there is always a risk that our trade secrets or know-how will be compromised or that a 
competitor could lawfully reverse-engineer our technology or independently develop similar or more efficient 
technology. We have confidentiality agreements with each of our customers, suppliers, key employees and 
independent contractors in place to protect our intellectual property rights, but it is possible that a customer, 
supplier, employee or contractor might breach the agreement, intentionally or unintentionally. For example, we 
believe a key former employee may have shared some of our intellectual property with a competitor in China and 
this former employee or the competitor may use this intellectual property to compete with us in the future. It is also 
possible that our confidentiality agreements with customers, suppliers, employees and contractors will not be 
effective in preserving the confidential nature of our intellectual property rights. The patents we own could be 
challenged, invalidated, narrowed or circumvented by others and may not be of sufficient scope or strength to 
provide us with any meaningful protection or commercial advantage. Once our patents expire, or if they are 
invalidated, narrowed or circumvented, our competitors may be able to utilize the inventions protected by our 
patents. Additionally, the existence of our intellectual property rights does not guarantee that we will be successful 
in any attempt to enforce these rights against third parties in the event of infringement, misappropriation or other 
misuse, which may materially and adversely affect our business. Because our ability to effectively compete in our 
industry depends upon our ability to protect our proprietary technology, we might lose business to competitors and 
our business, revenue, operating results and prospects could be materially harmed if we suffer loss of trade secret 
and know-how protection or breach of our confidentiality agreements.

If the transfer pricing arrangements we have among our subsidiaries are determined to be inappropriate in one 
or more jurisdictions, our tax liability may increase.

In many countries, including the United States, we are subject to transfer pricing and other tax regulations 
designed to ensure that appropriate levels of income are reported as earned in each jurisdiction in which we operate. 
These regulations require that any international transaction involving associated enterprises be on substantially the 
same basis as a transaction between unrelated companies dealing at arms’ length and that contemporaneous 
documentation be maintained to support the transfer prices. We have transfer pricing arrangements among our 
subsidiaries in relation to various aspects of our business. We consider the transactions among our subsidiaries to be 
substantially on arm’s-length terms. If, however, a tax authority in any jurisdiction reviews any of our tax returns 
and determines that the transfer prices and terms we have applied are not appropriate, or that other income of our 
affiliates should be taxed in that jurisdiction, we may incur increased tax liability, including accrued interest and 
penalties, which would cause our tax provision to increase, possibly materially. In addition, if the jurisdiction from 
which the income is reallocated does not agree with the reallocation, both jurisdictions could tax the same income, 
resulting in double taxation. If tax authorities were to allocate income to a higher tax jurisdiction, subject our income 
to double taxation, or assess interest and penalties, it would increase our consolidated tax liability, which could 
materially harm our business, operating results and financial condition.

34

Our insurance coverage may not cover all risks we face and insurance premiums may increase, which may 
hinder our ability to maintain sufficient coverage to cover losses we may incur.

We are exposed to risks inherent in the manufacturing of wind blades and other composite structures as well 

as the construction of our facilities, such as natural disasters, breakdowns and manufacturing defects that could harm 
persons and damage property. We maintain insurance coverage with licensed insurance carriers that limits our 
aggregate exposure to certain types of catastrophic losses. In addition, we self-insure for a portion of our claims 
exposure resulting from workers’ compensation and certain events of general liability. We accrue currently for 
estimated incurred losses and expenses, and periodically evaluate and adjust our claims accrued liability amount to 
reflect our experience. However, our insurance coverage may not be sufficient to cover the full amount of potential 
losses. In addition, there are some types of losses such as from warranty, hurricanes, terrorism, wars, or earthquakes 
where insurance is limited and/or not economically justifiable. If we were to sustain a serious uninsured loss or a 
loss exceeding the limits of our insurance policies, the resulting costs could have a material adverse effect on our 
business prospects, results of operations and financial condition. Further, our insurance policies provide for our 
premiums to be adjusted annually. If the premiums we pay for our policies increase significantly, we may be unable 
to maintain the same level of coverage we currently carry, or we will incur significantly greater costs to maintain the 
same level of coverage, including through higher deductibles.

We may be subject to significant liabilities and costs relating to environmental and health and safety 
requirements.

We are subject to various environmental, health and safety laws, regulations and permit requirements in the 

jurisdictions in which we operate governing, among other things, health, safety, pollution and protection of the 
environment and natural resources, the handling and use of hazardous substances, the generation, storage, treatment 
and disposal of wastes, and the cleanup of any contaminated sites. In June 2018, Iowa OSHA, a division of the Iowa 
Department of Labor, issued a citation and notification of penalty to us alleging that certain of our workplace 
practices and conditions at our Newton, Iowa wind blade manufacturing facility had violated the Iowa Occupational 
Safety and Health Act. Specifically, the citation cited us for multiple alleged violations and proposed that we pay an 
aggregate penalty of $0.2 million. In June 2018, we notified Iowa OSHA that we were contesting all of the alleged 
violations and proposed penalties. In June 2018, the Labor Commissioner of the Iowa Department of Labor 
subsequently filed a complaint with the State of Iowa Employment Appeal Board, petitioning the appeal board to 
affirm the citation and notification of penalty that Iowa OSHA issued to us. In July 2018, we then filed a response 
with the appeal board denying the substantive allegations of the complaint. A hearing date has been set for June 
2019 and the matter remains pending.

We have incurred, and expect to continue to incur, capital and operating expenditures to comply with such 
laws, regulations and permit requirements. While we believe that we currently are in material compliance with all 
such laws, regulations and permit requirements, any noncompliance may subject us to a range of enforcement 
measures, including the imposition of monetary fines and penalties, other civil or criminal sanctions, remedial 
obligations, and the issuance of compliance requirements restricting our operations. In addition, the future adoption 
of more stringent laws, regulations and permit requirements may require us to make additional capital and operating 
expenditures. Under certain environmental laws and regulations, liabilities also can be imposed for cleanup of 
currently and formerly owned, leased or operated properties, or properties to which we sent hazardous substances or 
wastes, regardless of whether we directly caused the contamination or violated any law. For example, we could have 
future liability relating to any contamination that remains from historic industrial operations by others at our 
properties. Additionally, some of our facilities have a long history of industrial operations and, in the past, 
contaminants have been detected and remediated at one of our facilities in Izmir, Turkey.

There can be no assurance that we will not in the future become subject to compliance requirements, 
obligations to undertake cleanup or related activities, or claims or proceedings relating to environmental, health or 
safety matters, hazardous substances or wastes, contaminated sites, or other environmental or natural resource 
damages, that could impose significant liabilities and costs on us and materially harm our business, operating results 
or financial condition.

35

Claims that we infringe, misappropriate or otherwise misuse the intellectual property rights of others could 
subject us to significant liability and disrupt our business.

Our competitors and third party suppliers of components and raw materials used in our products protect their 

intellectual property rights by means such as trade secrets and patents. In the future we may be sued for violations of 
other parties’ intellectual property rights, and the risk of this type of lawsuit will likely increase as our size, 
geographic presence and market share expand and as the number of competitors in our market increases. Any such 
claims or litigation, whether meritorious or not, could:

•

•

•

•

•

•

•

•

be time-consuming and expensive to defend;

divert the attention of our technical and managerial resources;

adversely affect our relationships with current or future customers;

require us to enter into royalty or licensing agreements with third parties, which may not be available on 
terms that we deem acceptable;

prevent us from operating all or a portion of our business or force us to redesign our manufacturing 
processes or products, which could be difficult, time-consuming and expensive;

limit the supply or increase the cost of key raw materials and components used in our products;

subject us to significant liability for damages or result in significant settlement payments; and

require us to indemnify our customers or suppliers.

Any of the foregoing could disrupt our business and materially harm our operating results and financial 
condition. In addition, intellectual property disputes have in the past arisen between our customers which negatively 
affected such customers’ demand for wind blades manufactured by us. If such intellectual property disputes 
involving, or between, one or more of our customers should arise in the future, our business could be materially 
harmed.

We may form joint ventures, or acquire businesses or assets, in the future, and we may not realize the benefits of 
those transactions.

We have, in the past, entered into joint ventures with third parties for the manufacture of wind blades. For 

example, we entered into joint ventures with third parties in both our Mexico and Turkey locations. We may create 
new or additional joint ventures with third parties, or acquire businesses or assets, in the future that we believe will 
complement or augment our existing business. We cannot assure you that, following any such joint venture or 
acquisition, we will achieve the expected synergies to justify the transaction. We may encounter numerous 
difficulties in manufacturing any new products resulting from a joint venture or acquisition that delay or prevent us 
from realizing their expected benefits or enhancing our business. If we enter into joint ventures or acquire businesses 
or assets with respect to promising markets, we may not be able to realize the benefit of those joint ventures or 
acquired businesses assets if we are unable to successfully integrate them with our existing operations and company 
culture.

Work disruptions resulting from our collective bargaining agreements could result in increased operating costs 
and materially harm our business, operating results and financial condition.

Certain of our employees in Turkey and Matamoros, Mexico, which in the aggregate represented 

approximately 35% of our workforce as of December 31, 2018, are covered by collective bargaining arrangements.  
In 2016, we entered into a three-year collective bargaining agreement with certain of our Turkish employees at our 
first Turkey facility. The agreement resulted in an average increase in pay of approximately 20% for employees 
covered by the agreement. In addition, beginning in 2017, these collective bargaining arrangements also covered 
similarly situated employees at our second Turkey facility. In March 2018, we entered into a collective bargaining 
agreement with a labor union for certain of our employees in our Matamoros, Mexico facility. In January 2019, 
thousands of workers employed in dozens of manufacturing facilities in Matamoros, Mexico, went on strike. In 
general, these workers, who were represented by several different labor unions, demanded a twenty percent increase 

36

in their wage rate and an annual bonus of approximately $1,700. On February 15, 2019, our manufacturing 
production employees in Matamoros, Mexico, who are represented by a labor union, went on strike also demanding 
a 20% increase in their hourly wage rate and the payment of an annual bonus of approximately $1,700 even though 
our collective bargaining agreement does not provide for an annual bonus. During this strike, our Matamoros 
manufacturing facility stopped production from February 15, 2019 until March 2, 2019. On March 2, 2019, we 
reached an agreement with the labor union to end the strike and we reopened our Matamoros manufacturing facility 
on March 3, 2019. 

Additionally, our other employees working at other manufacturing facilities may vote to be represented by a 

labor union in the future. There can be no assurance that we will not experience labor disruptions such as work 
stoppages or other slowdowns by workers at any of our facilities. Should significant industrial action, threats of 
strikes or related disturbances occur, we could experience further disruptions of operations and increased labor costs 
in Turkey, Mexico or other locations, which could materially harm our business, operating results or financial 
condition. Any such work stoppage or slow-down at any of our facilities could also result in additional expenses and 
possible loss of revenue for us.

Our information technology infrastructure could experience serious failures or disruptions, the failure of which 
could materially harm our business, operating results and financial condition.

Information technology is part of our business strategy and operations. It enables us to streamline operation 

processes, facilitate the collection and reporting of business data, and provide for internal and external 
communications. There are risks that information technology system failures, network disruptions and breaches of 
data security could disrupt our operations. Any significant disruption or breach may materially harm our business, 
operating results or financial condition.

We will incur significant increased costs as a result of operating as a public company, and our management will 
be required to devote substantial time to compliance initiatives.

As a public company, we incur significant legal, accounting and other expenses that we did not incur as a 

private company. In addition, the Sarbanes-Oxley Act, as well as rules subsequently implemented by the SEC and 
NASDAQ, impose various requirements on public companies, including requiring establishment and maintenance of 
effective disclosure controls and internal control over financial reporting and changes in corporate governance 
practices. Our management and other personnel will need to devote a substantial amount of time to these compliance 
initiatives. Moreover, these rules and regulations will increase our legal and financial compliance costs and will 
make some activities more time-consuming and costly. For example, we expect these rules and regulations to make 
it more difficult and more expensive for us to obtain director and officer liability insurance. We estimate that we will 
incur approximately $3.0 million to $4.0 million in expenses annually in response to these requirements. 

Section 404(a) of the Sarbanes-Oxley Act requires annual management assessments of the effectiveness of our 

internal control over financial reporting, starting with the second annual report that we file with the SEC. However, 
as long as we remain an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 
2012 (the JOBS Act), we intend to take advantage of certain exemptions from various reporting requirements that 
are applicable to other public companies that are not emerging growth companies including, but not limited to, not 
being required to comply with the auditor attestation requirements of Section 404(b) of the Sarbanes-Oxley Act. We 
will take advantage of these reporting exemptions until we are no longer an emerging growth company and will 
incur additional expense and time related to these efforts at that time. We will remain an emerging growth company 
until the earliest of (i) the last day of the fiscal year in which we have total annual gross revenues of $1.07 billion or 
more; (ii) the last day of our fiscal year following the fifth anniversary of the date of the completion of our IPO; 
(iii) the date on which we have issued more than $1.0 billion in nonconvertible debt during the previous three years; 
or (iv) the date on which we are deemed to be a “large accelerated filer” under SEC rules.

Our testing, or the subsequent testing by our independent registered public accounting firm, may reveal 

deficiencies in our internal control over financial reporting that are deemed to be material weaknesses. Our 
management and other personnel will need to devote a substantial amount of time to these compliance initiatives, 
diverting their attention away from the day-to-day management of our business, and we may not successfully or 
efficiently manage our transition into a public company. We may also need to upgrade our financial and operating 

37

systems, implement additional financial and management controls, reporting systems and procedures, and add 
additional accounting, auditing and financial staff with appropriate public company experience and technical 
accounting knowledge. We have or will soon have operations in China, Mexico, Turkey and India and may have 
difficulty hiring and retaining employees in these countries who have the experience necessary to implement the 
kind of management and financial controls that are expected of a U.S. public company. In this regard, for example, 
China has only recently begun to adopt management and financial reporting concepts and practices like those in the 
United States. If we are not able to comply with these requirements in a timely manner or if we or our independent 
registered public accounting firm identify deficiencies in our internal control over financial reporting that are 
deemed to be material weaknesses, the market price of our stock could decline, and we could be subject to sanctions 
or investigations by NASDAQ, the SEC or other regulatory authorities, which would require additional financial and 
management resources.

We are faced with increasingly complex tax issues in many jurisdictions, and we could be obligated to pay 
additional taxes in various jurisdictions.

We may be subject to taxation in many jurisdictions in the United States and around the world with 
increasingly complex tax laws, the application of which can be uncertain. The amount of taxes we pay in these 
jurisdictions could increase substantially as a result of changes in the applicable tax laws, including increased tax 
rates or revised interpretations of existing tax laws and precedents, which could harm our liquidity and operating 
results. In addition, the taxing authorities in these jurisdictions could review our tax returns, or authorities in 
jurisdictions in which we do not file tax returns could assert that we are subject to tax in those jurisdictions, and in 
either case could impose additional tax, interest and penalties. Further, the authorities could claim that various 
withholding requirements apply to us or our subsidiaries or assert that benefits of tax treaties are not available to us 
or our subsidiaries, any of which could have a material adverse impact on us and the results of our operations.

Risks Related to Ownership of Our Common Stock

The price of our common stock may fluctuate substantially and your investment may decline in value.

The market price of our common stock is likely to be highly volatile and may fluctuate substantially due to 

many factors, including:

•

•

•

•

•

•

•

•

•

•

•

•

•

actual or anticipated fluctuations in our results of operations;

our ability to provide products due to shipments subject to delayed delivery and deferred revenue 
arrangements;

loss of or changes in our relationship with one or more of our customers;

failure to meet our earnings estimates;

conditions and trends in the energy and manufacturing markets in which we operate and changes in 
estimates of the size and growth rate of these markets;

announcements by us or our competitors of significant contracts, developments, acquisitions, strategic 
partnerships or divestitures;

availability of equipment, labor and other items required for the manufacture of wind blades;

changes in governmental policies;

additions or departures of members of our senior management or other key personnel;

changes in market valuation or earnings of our competitors;

sales of our common stock, including sales of our common stock by our directors and officers or by our 
other principal stockholders;

the trading volume of our common stock; and

general market and economic conditions.

38

In addition, the stock market in general, including NASDAQ, as well as the market for broader energy and 

renewable energy companies in particular, have experienced extreme price and volume fluctuations that have often 
been unrelated or disproportionate to the operating performance of particular companies affected. These broad 
market and industry factors may materially harm the market price of our common stock, regardless of our operating 
performance. In the past, securities class-action litigation has often been instituted against a company following 
periods of volatility in the market price of that company’s securities. Securities class-action litigation, if instituted 
against us, could result in substantial costs or damages and a diversion of management’s attention and resources, 
which could materially harm our business and operating results.

A significant portion of our total outstanding shares may be sold into the public market in future sales, which 
could cause the market price of our common stock to drop significantly, even if our business is doing well.

Sales of a substantial number of shares of our common stock in the public market can occur at any time. These 

sales, or the market perception that the holders of a large number of shares intend to sell shares, could reduce the 
market price of our common stock. As of December 31, 2018, we had 34,678,084 shares of common stock 
outstanding. All shares can now be sold, subject to any applicable volume limitations under federal securities laws. 

In addition, as of December 31, 2018, there were: (i) 2,600,694 shares subject to outstanding options, or 7.5% 

of our outstanding shares; (ii) 425,876 restricted stock units, or 1.2% of our outstanding shares; (iii) 249,249 
performance stock units, or 0.7% of our outstanding shares; and (iv) 5,980,605 shares reserved for future issuance, 
or 17.2% of our outstanding shares under the Amended and Restated 2015 Stock Option and Incentive Plan (the 
2015 Plan) that will become eligible for sale in the public market to the extent permitted by any applicable vesting 
requirements and Rules 144 and 701 under the Securities Act. We also filed a shelf registration statement in 
September 2017 for the resale of up to 19,774,751 shares of common stock by certain of our common stockholders. 
We also have registered all shares of common stock that we may issue under our employee equity incentive plans. 
These shares can be freely sold in the public market upon issuance and subject to the restrictions imposed on our 
affiliates under Rule 144.

In the future, we may also issue our securities in connection with investments or acquisitions. The amount of 

shares of our common stock issued in connection with an investment or acquisition could constitute a material 
portion of our then-outstanding shares of our common stock. Any issuance of additional securities in connection 
with investments or acquisitions may result in additional dilution to you and may cause the market price of our 
common stock to drop significantly.

The exercise of options and warrants and other issuances of shares of common stock or securities convertible 
into common stock under our equity compensation plans will dilute your interest.

Under our existing equity compensation plans, as of December 31, 2018, we had outstanding options to 
purchase 2,600,694 shares of our common stock, 425,876 restricted stock units and 249,249 performance stock units 
to our employees and non-employee directors. From time to time, we expect to grant additional options and other 
stock awards in accordance with the 2015 Plan. The exercise of options and warrants at prices below the market 
price of our common stock could adversely affect the price of shares of our common stock. Additionally, any 
issuance of our common stock that is not made solely to then-existing stockholders proportionate to their interests, 
such as in the case of a stock dividend or stock split, will result in dilution to each stockholder by reducing their 
percentage ownership of the total outstanding shares. If we issue options or warrants to purchase our common stock 
in the future and those options or warrants are exercised or we issue stock, stockholders may experience further 
dilution. 

Our executive officers, directors and their affiliated entities may be able to exercise substantial control over us 
and could limit the ability of other stockholders to influence the outcome of key transactions, including changes 
of control.

Our executive officers, directors and their affiliated entities, in the aggregate, beneficially own approximately 
24% of the outstanding common stock, based on 34,914,385 shares of common stock outstanding as of January 31, 
2019. Our executive officers, directors and their affiliated entities, if acting together, may be able to control or 
significantly influence all matters requiring approval by our stockholders, including the election of directors and the 

39

approval of mergers or other significant corporate transactions. The concentration of common stock ownership could 
have the effect of delaying, preventing, or deterring a change of control of our company, could deprive our 
stockholders of an opportunity to receive a premium for their common stock as part of a sale of our company, and 
could negatively affect the market price of the common stock.

If equity research analysts issue unfavorable commentary or downgrade our common stock, the price of our 
common stock could decline.

The trading market for our common stock relies in part on the research and reports that equity research 
analysts publish about us and our business. We do not control the work performed by these analysts. The demand for 
our common stock could decline if one or more equity analysts downgrade our stock or if those analysts issue 
unfavorable or inaccurate commentary. If such analysts cease publishing reports about us or our business, we could 
lose visibility in the market, which in turn could cause our share price and trading volume to decline. 

We do not currently intend to pay dividends on the common stock, which may hinder your ability to achieve a 
return on your investment.

We have never declared or paid any cash dividends on our common stock. The continued operation and 
expansion of our business will require substantial funding and thus we currently intend to retain any future earnings 
and do not expect to pay any dividends in the foreseeable future. Accordingly, you are not likely to receive any 
dividends on common stock in the foreseeable future, and your ability to achieve a return on your investment will 
therefore depend on appreciation in the price of the common stock.

Provisions of Delaware law or our charter documents could delay or prevent an acquisition of our company, even 
if the acquisition would be beneficial to our stockholders, and could make it more difficult for you to change 
management.

Provisions of Delaware law and our amended and restated certificate of incorporation and amended and 
restated by-laws may discourage, delay or prevent a merger, acquisition or other change in control that stockholders 
may consider favorable, including transactions in which stockholders might otherwise receive a premium for their 
shares. These provisions may also prevent or delay attempts by stockholders to replace or remove our current 
management or members of our board of directors. These provisions include:

•

•

•

•

•

•

a classified board of directors;

limitations on the removal of directors;

advance notice requirements for stockholder proposals and nominations;

the inability of stockholders to act by written consent or to call special meetings;

the ability of our board of directors to make, alter or repeal our amended and restated by-laws; and

the authority of our board of directors to issue preferred stock with such terms as our board of directors 
may determine.

The affirmative vote of the holders of at least 75% of our shares of capital stock entitled to vote, and not less 
than 75% of the outstanding shares of each class entitled to vote thereon as a class, is necessary to amend or repeal 
the above provisions that are contained in our amended and restated certificate of incorporation. In addition, absent 
approval of our board of directors, our amended and restated by-laws may only be amended or repealed by the 
affirmative vote of the holders of at least 75% of our shares of capital stock entitled to vote.

In addition, we are subject to the provisions of Section 203 of the Delaware General Corporation Law, which 
limits business combination transactions with stockholders of 15% or more of our outstanding voting stock that our 
board of directors has not approved. These provisions and other similar provisions make it more difficult for 
stockholders or potential acquirers to acquire us without negotiation. These provisions may apply even if some 
stockholders may consider the transaction beneficial to them.

40

As a result, these provisions could limit the price that investors are willing to pay in the future for shares of 

our common stock. These provisions might also discourage a potential acquisition proposal or tender offer, even if 
the acquisition proposal or tender offer is at a premium over the then current market price for our common stock.

We are an “emerging growth company” and will be able to avail ourselves of reduced disclosure requirements 
applicable to emerging growth companies, which could make our common stock less attractive to investors.

We are an “emerging growth company,” as defined in the JOBS Act, and we intend to take advantage of 

certain exemptions from various reporting requirements that are applicable to other public companies that are not 
emerging growth companies including not being required to comply with the auditor attestation requirements of 
Section 404(b) of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our 
periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote 
on executive compensation and stockholder approval of any golden parachute payments not previously approved. 
We cannot predict whether investors will find our common stock less attractive because we may rely on these 
exemptions. If they do, there may be a less active trading market for our common stock and our stock price may be 
more volatile. We may take advantage of these reporting exemptions until we are no longer an emerging growth 
company. We will remain an emerging growth company until the earliest of (i) the last day of the fiscal year in 
which we have total annual gross revenues of $1.07 billion or more; (ii) the last day of our fiscal year following the 
fifth anniversary of the date of the completion of our IPO; (iii) the date on which we have issued more than $1.0 
billion in nonconvertible debt during the previous three years; or (iv) the date on which we are deemed to be a “large 
accelerated filer” under the rules of the SEC.

Under the JOBS Act, emerging growth companies can also delay adopting new or revised accounting 
standards until such time as those standards apply to private companies. We have irrevocably elected not to avail 
ourselves of this exemption from new or revised accounting standards and, therefore, we are subject to the same new 
or revised accounting standards as other public companies that are not emerging growth companies.

Item 3. Legal Proceedings

From time to time, we may be involved in disputes or litigation relating to claims arising out of our 

operations.

In March 2015, a complaint was filed against us in the Superior Court of the State of Arizona (Maricopa 
County) by a former employee, alleging that we had agreed to compensate the employee upon any future sale of the 
Company. We filed a motion to dismiss the complaint in April 2015, which was denied. We subsequently filed an
answer to the complaint in July 2015 denying the substantive allegations of the complaint. The parties completed 
court-ordered mediation in December 2015 but were not able to reach a settlement. We filed a motion for summary
judgment to dismiss the complaint in April 2016 and the court denied the motion in August 2016. The court has set a
trial date for June 2019. We continue to deny the substantive allegations of the complaint and intend to vigorously 
defend this lawsuit; however, we are currently unable to determine the ultimate outcome of this case.

42

In August 2015, we entered into a transition agreement with our former Senior Vice President – Asia, pursuant 

to which that individual transitioned out of this role at the end of 2015 and was to serve in a consulting capacity in 
2016 and 2017. In January 2016, following our discovery that the individual had materially violated the terms of the 
transition agreement, we terminated the consultancy for cause. In April 2016, an arbitration claim was filed in China 
by the individual with the Taicang Labor and Personnel Dispute Arbitration Committee alleging that we improperly 
terminated the transition agreement. The individual is demanding that we honor the terms of the transition 
agreement and pay compensation and fees under the transition agreement, which in the aggregate totals 
approximately $2.6 million. In addition, the individual is also challenging the validity of our termination of an 
option to purchase 164,880 shares of our common stock and 77,760 restricted stock units awarded under the 2015 
Plan, which were canceled in January 2016 when the consultancy was terminated. The Taicang Labor and Personnel 
Dispute Arbitration Committee awarded damages to the individual of approximately $1.2 million but rejected the 
claims regarding the termination of the stock option and restricted stock unit awards. We subsequently appealed the 
arbitration award in favor of the individual to the Taicang Municipal People’s Court, which affirmed the arbitration 
award in June 2018. We appealed this judgment to an appellate level court in the Jiangsu Province and the appellate 
court affirmed the judgment of the Taicang Municipal People’s court and we paid the judgement award in the fourth 
quarter of 2018. We currently are evaluating whether to further appeal this matter. 

In June 2018, Iowa OSHA, a division of the Iowa Department of Labor, issued a citation and notification of 

penalty to us alleging that certain of our workplace practices and conditions at our Newton, Iowa wind blade 
manufacturing facility had violated the Iowa Occupational Safety and Health Act. Specifically, the citation cited us 
for multiple alleged violations and proposed that we pay an aggregate penalty of $0.2 million. In June 2018, we 
notified Iowa OSHA that we were contesting all of the alleged violations and proposed penalties. In June 2018, the 
Labor Commissioner of the Iowa Department of Labor subsequently filed a complaint with the State of Iowa 
Employment Appeal Board, petitioning the appeal board to affirm the citation and notification of penalty that Iowa 
OSHA issued to us. In July 2018, we then filed a response with the appeal board denying the substantive allegations 
of the complaint. A hearing date has been set for June 2019 and the matter remains pending. 

From time to time, we are party to various lawsuits, claims, and other legal proceedings that arise in the 
ordinary course of business, some of which are covered by insurance. Upon resolution of any pending legal matters, 
we may incur charges in excess of presently established reserves. Our management does not believe that any such 
charges would, individually or in the aggregate, have a material adverse effect on our financial condition, results of 
operations or cash flows.

As of January 31, 2019, there were five stockholders of record of our common stock, although there is a much 

larger number of beneficial owners.

Dividends

We have never declared or paid any cash dividends on shares of our capital stock. We currently intend to 
retain earnings, if any, to finance the development and growth of our business and do not anticipate paying cash 
dividends on the common stock in the future. Any payment of any future dividends will be at the discretion of the 
board of directors, subject to compliance with certain covenants in our loan agreements, after taking into account 
various factors, including our financial condition, operating results, capital requirements, restrictions contained in 

44

any future financing instruments, growth plans and other factors the board deems relevant. See “Management’s 
Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and Capital Resources” 
included in Part II, Item 7.

Certain of our subsidiaries are limited in their ability to declare dividends without first meeting statutory 

restrictions of the People’s Republic of China, including retained earnings as determined under Chinese-statutory 
accounting requirements. Until 50% ($21.6 million) of registered capital is contributed to a surplus reserve, our 
Chinese 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, we can pay dividends equal to 100% of after-tax profit 
assuming other conditions are met. At December 31, 2018, the amount of the surplus reserve fund was $6.5 million. 
See “Management’s Discussion and Analysis of Financial Condition and Results of Operations— Liquidity and 
Capital Resources” included in Part II, Item 7.

Use of Proceeds from Registered Securities

On July 21, 2016, our Registration Statement on Form S-1 (File No. 333-212093) was declared effective by 

the SEC for our IPO whereby we registered an aggregate of 7,187,500 shares of our common stock, including 
937,500 shares of our common stock registered for sale by us upon the full exercise of the underwriters’ option to 
purchase additional shares. On July 27, 2016, we completed our IPO and sold 7,187,500 shares of our common 
stock at a price to the public of $11.00 per share. J.P. Morgan Securities LLC and Morgan Stanley & Co. LLC acted 
as the managing underwriters. The total gross proceeds from the offering to us were $79.1 million. After deducting 
underwriting discounts and commissions of $4.6 million and offering expenses of $7.3 million, we received $67.2 
million in net proceeds. There has been no material change in the planned use of proceeds from our IPO as described 
in our final prospectus filed with the SEC on July 22, 2016 pursuant to Rule 424(b) of the Securities Act. We 
invested the remaining funds received in registered money market funds.

OVERVIEW

Our Company

We are the largest and only independent manufacturer of composite wind blades for the wind energy market 
with a global manufacturing footprint. We enable many of the industry’s leading wind turbine original equipment 
manufacturers (OEM), who have historically relied on in-house production, to outsource the manufacturing of some 
of their wind blades through our global footprint of advanced manufacturing facilities strategically located to serve 
large and growing wind markets in a cost-effective manner. Given the importance of wind energy capture, turbine 
reliability and cost to power producers, the size, quality and performance of wind blades have become highly 
strategic to our OEM customers. As a result, we have become a key supplier to our OEM customers in the 
manufacture of wind blades and related precision molding and assembly systems. We have entered into long-term 
supply agreements pursuant to which we dedicate capacity at our facilities to our customers in exchange for their 
commitment to purchase minimum annual volumes of wind blade sets, which consist of three wind blades. This 
collaborative dedicated supplier model provides us with contracted volumes that generate significant revenue 
visibility, drive capital efficiency and allow us to produce wind blades at a lower total delivered cost, while ensuring 
critical dedicated capacity for our customers.  

We also leverage our advanced composite technology and history of innovation to supply high strength, 
lightweight and durable composite products to the transportation market.  In November 2017, we signed a five-year 
supply agreement with Proterra Inc. (Proterra) to supply Proterra Catalyst® composite bus bodies from our existing 
Rhode Island facility and also from a new manufacturing facility in Newton, Iowa which commenced operations in 
the second quarter of 2018. In February 2018, we entered into an agreement with Navistar, Inc. (Navistar) to design 
and develop a Class 8 truck comprised of a composite tractor, trailer and frame rails. This collaborative development 
project was entered into in connection with Navistar’s recent award under the Department of Energy’s (DOE) Super 
Truck II investment program, which is designed to promote fuel efficiency in commercial vehicles. In November 
2018, we announced a capital investment of approximately $11.5 million in 2019 to develop a highly automated 
pilot manufacturing line for the electric vehicle market. We plan to locate this pilot line adjacent to our second 
Newton, Iowa location where we manufacture composite bus bodies for Proterra. We expect this investment will 
enable us to further develop our technology, create defensible product and process IP and demonstrate our capability 
to manufacture composite components cost effectively at automotive volume rates. We also expect this pilot line 
will also help our current and potential customers to de-risk the decision-making process to commit to TPI for high-
volume manufacturing programs in the future.

Our wind blade and precision molding and assembly systems manufacturing businesses accounted for 
approximately 95%, 96% and 97% of our total net sales for each of the years ended December 31, 2018, 2017 and 
2016, respectively.  As of February 28, 2019, our long-term wind and transportation supply agreements provide for 
minimum aggregate volume commitments from our customers of approximately $4.0 billion and encourage our 
customers to purchase additional volume up to, in the aggregate, a total contract value of approximately $6.8 billion 
through the end of 2023. In recent years, we have experienced significant growth in our OEM customer base, as 
according to data from WoodMac, our OEM customers collectively accounted for approximately 54% of the global 
onshore wind energy market and approximately 90% of that market excluding China over the three years ended 
December 31, 2017, based on MWs of energy capacity installed. Additionally, our customers represented 99.8% of 
the U.S. onshore wind turbine market over the three years ended December 31, 2017, based on MWs of energy 
capacity installed. We believe these figures demonstrate the leading position of our existing OEM customers, as well 

49

as our opportunity to develop relationships with new OEM customers as additional OEMs seeking to capitalize on 
the benefits of outsourced wind blade manufacturing while maintaining high quality customization and dedicated 
capacity. We believe that these trends will help us to strengthen our current customer base, grow our business 
worldwide, increase our revenue and improve our business prospects.

We divide our business operations into four geographic operating segments—the United States (U.S.), Asia, 

Mexico and Europe, the Middle East, Africa and India (EMEAI), as follows:

•

•

•

•

Our U.S. segment includes (1) the manufacturing of wind blades at our Newton, Iowa plant, (2) the 
manufacturing of precision molding and assembly systems used for the manufacture of wind blades at 
our Warren, Rhode Island facility, (3) the manufacturing of composite solutions for the transportation 
industry, which we also conduct at our existing Rhode Island facility as well as at our Fall River, 
Massachusetts facility and at a second manufacturing facility in Newton, Iowa which commenced 
operations in the second quarter of 2018, (4) wind blade inspection and repair services in North 
America, (5) our advanced engineering center in Kolding, Denmark, which provides technical and 
engineering resources to our manufacturing facilities and (6) our corporate headquarters, the costs of 
which are included in general and administrative expenses. 

Our Asia segment includes (1) the manufacturing of wind blades at our facilities in Taicang Port, China; 
Dafeng, China and Yangzhou, China, the latter of which we expect to commence operations in the first 
quarter of 2019, (2) the manufacturing of precision molding and assembly systems at our Taicang City, 
China facility and (3) wind blade inspection and repair services.

Our Mexico segment manufactures wind blades from three facilities in Juárez, Mexico and a facility in 
Matamoros, Mexico at which we commenced operations in the third quarter of 2018. In November 
2018, we entered into a new lease agreement with a third party for a new precision molding and 
assembly systems manufacturing facility in Juárez, Mexico and we expect to commence operations at 
this facility in the first quarter of 2019. This segment also performs wind blade inspection and repair 
services. 

Our EMEAI segment manufactures wind blades from two facilities in Izmir, Turkey and also performs 
wind blade inspection and repair services. In February 2019, we entered into a new lease agreement 
with a third party for the construction of a new manufacturing facility that will be built near Chennai, 
India and we expect to commence operations at this facility in the first half of 2020.

Key Trends Affecting our Business  

We have identified the following material trends affecting our business: 

•

•

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. We expect our revenue growth rate in 2019 to accelerate considerably due to the full year of 
operations in our plant in Matamoros, Mexico, the planned opening of our Yangzhou, China 
manufacturing facility in the first quarter of 2019 and the completion of multiple blade model transitions 
and startups in 2018.  We expect to continue to have a high level of manufacturing lines in transition 
and startup in 2019. We have entered into long-term supply agreements with customers in the United 
States, China, Mexico, Turkey and India that expire between 2020 and 2023. 

Many governments are shifting from feed-in tariffs to auction-based tenders as a means of promoting 
the development and growth of renewable energy sources such as wind energy.  As a result of this shift, 
our wind turbine OEM customers have experienced intense pricing pressure with respect to the sale of 
their turbines together with increased competitive pricing from solar energy.  To date, these pricing 
pressures have not materially affected our results of operations, however, if these pricing pressures 
continue, we may be required to reduce our margins or choose to pass on the savings obtained from 
manufacturing cost reductions and productivity improvements to our OEM customers to remain 
competitive.  

50

•

•

•

•

•

•

During the last several years, wind turbine OEMs generally have increasingly outsourced the production 
of wind blades and other key components to specialized manufacturers to meet this 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 six OEM 
customers since 2013, 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. 

Despite the trend of wind turbine OEMs increasingly outsourcing their wind blade manufacturing 
production requirements, we expect GE Wind, our second largest customer, to insource a greater 
percentage of its wind blade production requirements as a result of its 2017 acquisition of LM, our 
largest competitor. Although GE Wind did not extend our Turkey and Taicang Port, China supply 
agreements which expired at the end of 2017, since then we have extended our existing supply 
agreement in one of our Mexico plants by two years to 2022 and have increased the number of lines 
under contract with GE Wind by two in that facility. In addition, GE Wind has agreed to transition to a 
larger blade model in our Newton, Iowa plant in early 2019 and to eliminate its option to terminate their 
supply agreement at this location prior to its December 2020 expiration. 

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 may not always fully 
cover the transition costs and lost margin. As a result, these transitions have and may continue to have a 
short-term, negative impact on our consolidated operating results and cash flows. However, our 
precision molding and assembly manufacturing business generally increases as we transition to larger 
wind blade models and larger wind blades generally have a higher average selling price, so that the 
transition to larger wind blades may increase our net sales over time. As we transition to new wind 
blade models, we also often extend our existing supply agreements. 

The financial performance of certain of our smaller wind turbine OEM customers has deteriorated over 
the last twelve months. As a result, we expect that in certain instances overall demand for our wind 
turbine blades from these customers may decline in 2019 compared to our prior forecasts. However, we 
expect this decline in demand to be offset by an increase in demand from certain of our other larger 
OEM customers.

We expect that a substantial portion of our future revenue growth will be derived from our international 
operations. We have expanded our manufacturing facilities internationally over the last several years, 
including opening facilities in Mexico, Turkey and China, to meet the needs of our customers. In 
February 2019, we entered into a new lease agreement with a third party for the construction of a new 
manufacturing facility that will be built near Chennai, India and we expect to commence operations at 
this facility in the first half of 2020. The portion of our net sales that were derived from our international 
operations increased to 84% for the year ended December 31, 2018, from 80% for the year ended 
December 31, 2017 and 75% for the year ended December 31, 2016. We believe we will continue to 
derive a substantial portion of our future net sales growth from our international operations. 

Our long-term supply agreements with our customers generally encourage our customers to maximize 
the volume of wind blades they purchase from us, since purchasing less than a specified amount triggers 
higher pricing, as well as provide downside protection for us through minimum annual volume 
commitments. Some of our long-term supply agreements also provide for annual sales price reductions 
reflecting assumptions regarding increases in our manufacturing efficiency and productivity. We work 
to continue to drive down the cost of materials and production through innovation and global sourcing, a 
portion of the benefit of which we share with our customers contractually, further strengthening our 
deep customer relationships. Wind blade pricing is based on annual commitments of volume as 
established in the customer’s contract, with orders less than committed volume resulting in additional 
costs per wind blade to customers. Orders in excess of annual commitments may but generally do not 
result in discounts to customers from the contracted price for the committed volume. Customers may 
utilize early payment discounts, which are reported as a reduction of revenue at the time the discount is 
taken. 

51

•

•

•

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 that we have 
dedicated to a particular customer 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 28, 2019, our long-term wind and 
transportation supply agreements provide for minimum aggregate volume commitments from our 
customers of approximately $4.0 billion and encourage our customers to purchase additional volume up 
to, in the aggregate, a total contract value of approximately $6.8 billion through the end of 2023. 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. 
Additionally, some of our contracts allow our customers to reduce the number of lines under contract 
without penalty, prior to the end of the contact term. 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 the number of lines under contract are reduced. 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. 

We expect our new manufacturing facilities to generally generate operating losses in their first 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. For planning 
purposes, we generally estimate that the startup of a new six-line manufacturing facility requires cash 
for net operating expenses and working capital of between $20 million to $25 million. We also estimate 
that capital expenditures, primarily for machinery and equipment, of between $30 million to $35 million 
will be required. We expect to incur significant startup costs and expenses during 2019 in connection 
with the planned opening of our new manufacturing facility in Chennai, India and at our Yangzhou, 
China; Matamoros, Mexico and Newton, Iowa facilities.   

As a public company, we incur significant legal, accounting and other expenses. In addition, the 
Sarbanes-Oxley Act, as well as rules subsequently implemented by the SEC and NASDAQ, impose 
various requirements on public companies, including requiring establishment and maintenance of 
effective disclosure controls and internal control over financial reporting and changes in corporate 
governance practices. We estimate that we will incur approximately $3.0 million to $4.0 million in 
expenses annually in response to these requirements.

COMPONENTS OF RESULTS OF OPERATIONS

Net Sales 

We recognize revenue from manufacturing services over time as the customer controls 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.

52

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 manufacture of our products and services.

Startup costs represent the unallocated overhead related to both new manufacturing facilities as well as new 

lines in existing manufacturing facilities. Transition costs represent the unallocated overhead related to the transition 
of wind blade models. The startup and transition costs are primarily fixed overhead costs incurred during the period 
production facilities are under-utilized while transitioning wind blade models and ramping up manufacturing, which 
are not allocated to products and are expensed as incurred. 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, manufacturing overhead as a percentage of net sales is 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 are primarily 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. In addition, realized losses on the sale of receivables, under supply chain 
financing arrangements with our customers, and realized gains and losses on the sale of other assets at our 
manufacturing facilities are also included in general and administrative expenses. 

The research and development expenses incurred at our Warren, Rhode Island and Fall River, Massachusetts 

locations as well as at our Kolding, Denmark advanced engineering center are included in general and administrative 
expenses. For the years ended December 31, 2018, 2017 and 2016, total research and development expenses totaled 
$0.8 million, $1.6 million and $1.5 million, respectively. 

For the year ended December 31, 2018, the realized loss on the sale of certain receivables, on a non-recourse 

basis under supply chain financing arrangements with our customers, to financial institutions and the realized loss on 
the sale of other assets at our manufacturing facilities totaled $4.6 million. There were no such amounts for the years 
ended December 31, 2017 and 2016. 

Other Income (Expense)

Other income (expense) consists primarily of interest expense on our debt borrowings and the amortization of 

deferred financing costs on such borrowings. Other income (expense) also includes realized gains and losses on 
foreign currency remeasurement, interest income, losses on extinguishment of debt and miscellaneous income and 
expense.

53

During the year ended December 31, 2018, we expensed $2.0 million of deferred financing costs and $1.4 

million of prepayment penalties related to the refinancing of our previous credit facility within the caption “Loss on 
extinguishment of debt” in the accompanying consolidated income statements. During the year ended December 31,
2016, we expensed $2.4 million of deferred financing costs and $2.1 million of prepayment penalties related to the 
refinancing of our previous credit facility with the caption “Loss on extinguishment of debt” in the accompanying 
consolidated income statements.

Income Tax Benefit (Provision)

Income tax benefit (provision) 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 and Turkey. The composite 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

Net Income Attributable to Preferred Stockholders

Net income attributable to preferred stockholders relates to the accrual of dividends on our convertible and 
senior redeemable preferred shares, the accretion to redemption amounts on our convertible preferred shares and 
warrant fair value adjustment. Immediately prior to the closing of our IPO, all preferred shares were converted into 
shares of our common stock and as a result, the accrual of dividends ceased.

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 total billings, 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 invoiced, estimated megawatts of energy capacity for wind blade sets invoiced, manufacturing lines dedicated to
customers under long-term supply agreements, total manufacturing lines installed, manufacturing lines in startup and 
manufacturing lines in transition, which help us evaluate our operational performance. We believe that these 
measures are useful to investors in evaluating our performance.

Net sales and total billings

We define total billings, a non-GAAP financial measure, as the total amounts we have invoiced our customers

for products and services for which we are entitled to payment under the terms of our long-term supply agreements
or other contractual agreements. We monitor total billings, and believe it is useful to present to investors as a 
supplement to our GAAP measures, because we believe it more directly correlates to sales activity and operations
based on the timing of actual transactions with our customers, which facilitates comparison of our performance 
between periods and provides a more timely indication of trends in sales. Under GAAP, total net sales recognized on 
products in production represents the total amount that we have recognized as revenue under the cost-to-cost method 
for services performed during the period under our long-term supply agreements. Under our long-term supply 
agreements with our customers, we invoice our customers for wind blades once the blades pass certain acceptance
procedures and title passes to our customers. Our customers generally pay us for the wind blades between 15 to 90
days after receipt of the invoice based on negotiated payment terms. However, in many cases, our customers request 
that we store their wind blades until they are ready to assemble wind turbines at a particular wind farm project. We 
have no control over when our customers decide to ship wind blades from our storage sites, and in some cases, our 
customers have stored large numbers of their wind blades on our sites for six months or more. However, we are 
contractually entitled to payment for those wind blades and, accordingly, invoice them when the blades are placed in 
storage.  

55

Our use of total billings 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:

•

•

Total billings includes wind blades that have not been delivered and for which we are responsible if 
damage occurs to them while we hold them; and

Other companies, including companies in our industry, may define total billings differently, which 
reduces its usefulness as a comparative measure.

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 realized gains 
or losses from foreign currency remeasurement, plus or minus any gains or losses from the sale of assets. 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, the Credit Facility 
contains minimum EBITDA (as defined in the Credit Facility) 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;

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 the realized gains or losses from foreign currency remeasurement in 
our international operations;

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 realized gains or losses on the sale of assets; 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 in this presentation. 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.

56

Free cash flow

We define free cash flow as net cash provided by 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 and 
discounts. 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 plants and expanding existing plants, as well as for 
capital expenditure requirements.

Key Operating Metrics

Key operating metrics consist of sets invoiced, estimated megawatts of energy capacity for wind blade sets

invoiced, dedicated manufacturing lines, total manufacturing lines installed, manufacturing lines in startup and 
manufacturing lines in transition. 

Sets represents the number of wind blade sets, consisting of three wind blades each, which we invoiced 

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 and total billings

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

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 from
customers under our long-term supply agreements in any given period. We believe that dedicated manufacturing 
lines provide an understanding of additional capacity within an existing facility. Dedicated manufacturing lines 
primarily impacts our net sales and total billings.

Total manufacturing lines installed represents the number of wind blade manufacturing lines installed and 

either in operation, startup or transition at the end of 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. 

Manufacturing lines in startup is the number of wind blade manufacturing lines that were in a startup phase 
during the pre-production and production ramp up period, pursuant to the opening of a new manufacturing facility,
the expansion of an existing manufacturing facility or the addition of new manufacturing lines in an existing 
manufacturing facility. We monitor and present this metric because we believe it helps investors to better understand 
the impact of the startup phase of our new manufacturing facilities on our gross profit and net income. 

Manufacturing lines in transition is the number of wind blade manufacturing lines that were being transitioned 

to a new wind blade model during the period. We monitor and present this metric because we believe it helps 
investors to better understand the impact of these transitions on our gross profit and net income.

Net sales for the year ended December 31, 2018 increased by $74.4 million or 7.8% to $1,029.6 million 
compared to $955.2 million in the same period in 2017. Net sales of wind blades increased by 4.8% to $933.3 
million for the year ended December 31, 2018 as compared to $890.5 million in the same period in 2017. The 
increase was primarily driven by higher average sales prices due to the mix of wind blade models produced during 
the year ended December 31, 2018 compared to the same period in 2017. This increase was partially offset by a 12% 
decrease in the number of wind blades produced year over year due to the number of transitions and startups during
the 2018 period as well as the loss of volume from two contracts that expired at the end of 2017. Net sales from the 
manufacturing of precision molding and assembly systems during the year ended December 31, 2018 increased to 
$48.9 million from $27.6 million in the same period in 2017. This increase was primarily the result of our customers 
requiring more precision molding and assembly systems from our tooling facilities during the year ended 
December 31, 2018 as compared to the same period in 2017 as a result of the blade transitions and startups during 
2018. Additionally, there was a $10.4 million increase in transportation and other sales during the year ended 
December 31, 2018 as compared to the same period in 2017. Total billings for the year ended December 31, 2018 
increased by $65.0 million or 6.9% to $1,006.5 million compared to $941.6 million in the same period in 2017. The 
impact of the fluctuating U.S. dollar against the Euro at our Turkey operations and the Chinese Renminbi at our 
China operations on consolidated net sales and total billings for the year ended December 31, 2018 as compared to
2017 was not significant.

Total cost of goods sold for the year ended December 31, 2018 was $956.8 million and included $61.9 million 

related to startup costs in our new plants in Turkey, Mexico, Iowa and China, the startup costs related to a new
customer in Taicang, China and $12.8 million of transition costs due to the number of transitions during the period. 
This compares to total cost of goods sold for the year ended December 31, 2017 of $844.7 million and included 
$40.6 million related to startup costs in our new plants in Turkey and Mexico and the startup of new wind blade 
models for certain of our customers in Turkey and Dafeng, China. Cost of goods sold as a percentage of net sales 
increased by approximately five percentage points during the year ended December 31, 2018 as compared to the 
same period in 2017, driven by the $34.1 million increase in startup and transition costs, partially offset by the 
impact of savings in raw material costs. The impact of the fluctuating U.S. dollar against the Euro, Turkish Lira,
Chinese Renminbi and Mexican Peso decreased consolidated cost of goods sold by 2.2% for the year ended 
December 31, 2018 as compared to 2017.

59

General and administrative expenses for the year ended December 31, 2018 totaled $48.1 million, or $43.5 

million excluding the realized loss on the sale of certain receivables, on a non-recourse basis under supply chain
financing arrangements with our customers, to financial institutions and the realized loss on the sale of other assets
at our manufacturing facilities totaling $4.6 million, as compared to $40.4 million of general and administrative 
expenses for the same period in 2017. As a percentage of net sales, general and administrative expenses, excluding
the realized loss on the sale of certain receivables and other assets, was 4.2% for the year ended December 31, 2018, 
comparable to the same period in 2017. The increase in expenses was primarily driven by additional costs incurred 
related to the implementation of ASU 2014-09, Revenue from Contracts with Customers (Topic 606), costs related 
to the Sarbanes-Oxley Act and our advanced engineering center, increased personnel costs from filling our key 
global positions to support our growth and diversification strategy as well as additional depreciation expense related 
to our enhanced corporate infrastructure.

Other expense totaled $22.5 million for the year ended December 31, 2018 as compared to $15.6 million for 
the same period in 2017. The increase was primarily due to a $9.0 million increase in the realized losses on foreign 
currency remeasurement primarily related to the change in the Turkish Lira during 2018 and the expensing of $3.4
million of deferred financing costs and prepayment penalties related to the refinancing of our previous credit facility
in 2018, partially offset by a $3.5 million increase in miscellaneous income for the year ended December 31, 2018 
as compared to the same period in 2017. 

Income taxes reflected a benefit of $3.0 million for the year ended December 31, 2018 as compared to a

provision of $15.8 million for the same period in 2017. The decrease was primarily due to the reduction in pretax
income and the reversal of our valuation allowances related to our U.S. federal deferred tax assets in the 2018
period. 

Net income for the year ended December 31, 2018 was $5.3 million as compared to $38.7 million in the same 

period in 2017. The decrease was primarily due to the reasons set forth above. Diluted earnings per share for the 
year ended December 31, 2018 was $0.15 compared to $1.11 for the year ended December 31, 2017.

U.S. Segment

Net sales in the year ended December 31, 2018 decreased by $27.3 million or 14.3% to $163.7 million 
compared to $191.0 million in the same period in 2017. Net sales of wind blades decreased to $126.3 million during 
the year ended December 31, 2018 from $164.9 million in the same period of 2017. The decrease was primarily due 
to an 8% reduction in the number of wind blades produced in the year ended December 31, 2018 as compared to the 
same period in 2017 and a decline in the average sales prices of the same wind blade models delivered in both 
periods as a result of savings in raw material costs, a portion of which we share with our customer. Net sales from 
the manufacturing of precision molding and assembly systems during the year ended December 31, 2018 were $5.0 
million compared to $8.4 million during the same period in 2017. Additionally, there was a $14.6 million increase in 
transportation and other sales during the year ended December 31, 2018 as compared to 2017. 

The loss from operations for the year ended December 31, 2018 was $67.4 million as compared to a loss of $33.2 

million in the same period in 2017. These amounts include corporate general and administrative costs of $43.5 million 
and $40.4 million for the years ended December 31, 2018 and 2017, respectively. The increase in the corporate general 
and administrative costs was primarily driven by additional costs incurred related to the implementation of Topic 606, 
costs related to the Sarbanes-Oxley Act and our advanced engineering center, increased personnel costs from filling our 
key global positions to support our growth and diversification strategy as well as additional depreciation expense 
related to our enhanced corporate infrastructure. The operating results were also unfavorably impacted by the startup 
costs related to our second Iowa facility and the lower wind blade volume discussed above.

Asia Segment

Net sales in the year ended December 31, 2018 decreased by $66.3 million or 17.8% to $306.3 million 
compared to $372.5 million in the same period in 2017. Net sales of wind blades were $264.4 million in the year 
ended December 31, 2018 as compared to $346.2 million in the same period of 2017. The decrease was primarily 
due to a 36% decrease in the number of wind blades produced during the year ended December 31, 2018 compared 
to the same period in 2017 primarily due to the expiration of a contract at the end of 2017 and the delayed startup of 
a new customer in 2018. This decrease was partially offset by a higher average sales prices due to the mix of wind 
blade models produced during the year ended December 31, 2018 compared to the same period in 2017. Net sales 
from the manufacturing of precision molding and assembly systems totaled $36.6 million during the 2018 period 
compared to $18.4 million during the same period in 2017. The impact of the fluctuating U.S. dollar against the 
Chinese Renminbi had a favorable impact of 0.6% on net sales during the year ended December 31, 2018 as 
compared to the same period in 2017.

Income from operations in the Asia segment for the year ended December 31, 2018 was $28.1 million as 
compared to $76.3 million in the same period in 2017. This decrease was driven by the startup costs incurred at our 
Taicang Port plant for a new customer and lower wind blade volume discussed above. The fluctuating U.S. dollar 
against the Chinese Renminbi had a favorable impact of 1.1% on cost of goods sold for the year ended 
December 31, 2018 as compared to the comparable 2017 period.

Mexico Segment

Net sales in the year ended December 31, 2018 increased by $62.2 million or 30.1% to $268.8 million 
compared to $206.6 million in the same period in 2017. The increase reflects an 18% net increase in overall wind 
blade volume driven by greater volume at our second and third Mexico plants, partially offset by a decrease in wind 
blade volume at our first Mexico plant. These increases were also impacted by an increase in the average sales 
prices of wind blades due to a change in the mix of wind blades between the two comparable periods.

Income from operations in the Mexico segment for the year ended December 31, 2018 was $12.2 million as 

compared to $14.4 million in the same period in 2017. The decrease was driven by higher startup costs related to our 
new facility in Matamoros, Mexico, partially offset by the overall increase in wind blade volume noted above as 
well as from savings in raw material costs and production efficiencies. 

61

EMEAI Segment

Net sales during the year ended December 31, 2018 increased by $105.8 million or 57.2% to $290.9 million 
compared to $185.1 million in the same period in 2017. The increase was driven by a 77% increase in wind blade 
production in our second Turkey plant, partially offset by a 11% decrease in wind blade volume at our first Turkey
plant as a result of the December 31, 2017 conclusion of our supply agreement with GE. Other items having a 
favorable impact on net sales include overall higher average sales prices of wind blades delivered in the comparative 
periods due to the beginning of wind blade production in our second Turkey plant and the mix of wind blades sold 
during the period.  The fluctuation of the U.S. dollar relative to the Euro had a 1.0% unfavorable impact on net sales
in the year ended December 31, 2018 as compared to 2017.  

The income from operations in the EMEAI segment for the year ended December 31, 2018 was $51.8 million

as compared to $12.6 million in the same period in 2017. The increase was primarily driven by the wind blade 
production in our second Turkey plant, improved operating efficiency at our first Turkey plant and savings in raw
materials. The fluctuation of the U.S. dollar relative to the Turkish Lira and Euro had a 7.5% favorable impact on 
cost of goods sold in the year ended December 31, 2018 as compared to 2017.

Net sales for the year ended December 31, 2017 increased by $186.2 million or 24.2% to $955.2 million 
compared to $769.0 million in the same period in 2016. Net sales of wind blades increased by 25.0% to $890.5 
million for the year ended December 31, 2017 as compared to $712.4 million in the same period in 2016. The 
increase was primarily driven by a 30% increase in the number of wind blades produced during 2017 as compared to
2016. This increase was partially offset by lower average sales price due to geographic mix, blade mix and the result 
of savings in raw material costs, a portion of which we share with our customers. Net sales from the manufacturing 
of precision molding and assembly systems during the year ended December 31, 2017 decreased to $27.6 million
from $35.9 million in the same period in 2016. This decrease was primarily the result of reduced demand from our 
customers for precision molding and assembly systems from our Rhode Island facility. Additionally, there was a
$16.3 million increase in transportation and other sales during the year ended December 31, 2017 as compared to the 
same period in 2016. Total billings for the year ended December 31, 2017 increased by $177.1 million or 23.2% to 
$941.6 million compared to $764.4 million in the same period in 2016. The impact of the fluctuating U.S. dollar 
against the Euro at our Turkey operations and the Chinese Renminbi at our China operations on consolidated net 
sales and total billings for the year ended December 31, 2017 as compared to 2016 was not significant. 

62

Total cost of goods sold for the year ended December 31, 2017 was $844.7 million and included $40.6 million 
related to startup costs in our new plants in Turkey and Mexico and the startup of new wind blade models for certain 
of our customers in Turkey and Dafeng, China. This compares to total cost of goods sold for the year ended 
December 31, 2016 of $682.2 million which included aggregate costs of $18.1 million related to startup costs in our 
new plants in Mexico and Turkey as well as the transition of wind blade models in our original plant in Mexico. 
Cost of goods sold as a percentage of net sales remained consistent during the year ended December 31, 2017 as 
compared to the same period in 2016 driven by improved operating efficiency in China and the impact of savings in 
raw material costs and foreign currency fluctuations, offset by higher operating costs in our Turkey and Mexico 
plants due to the startup costs incurred with the opening of new plants in both those segments. The impact of the 
fluctuating U.S. dollar against the Euro, Turkish Lira, Chinese Renminbi and Mexican Peso decreased consolidated 
cost of goods sold by 1.7% for the year ended December 31, 2017 as compared to 2016. 

General and administrative expenses for the year ended December 31, 2017 totaled $40.4 million as compared 
to $33.9 million for the same period in 2016. As a percentage of net sales, general and administrative expenses were 
4.2% for the year ended December 31, 2017, down from 4.4% in the same period in 2016. The increase in expenses 
was primarily driven by additional costs incurred related to the implementation of Topic 606, costs related to the 
Sarbanes-Oxley Act and our secondary public offering, increased personnel costs from filling our key global 
positions to support our growth and diversification strategy, partially offset by a $2.3 million decrease in share-
based compensation costs in the 2017 period as compared to the same period in 2016, which was the period in which 
we recorded the expense from the original grant date of the awards.

Other expense totaled $15.6 million for the year ended December 31, 2017 as compared to $22.3 million for 
the same period in 2016. The decrease was primarily due a $9.7 million decrease in interest expense, related to the 
expensing of $4.5 million of deferred financing costs and prepayment penalties related to the refinancing of our 
previous credit facility in 2016 and the decrease in 2017 non-cash interest expense due to the write off in 2016 of the 
beneficial conversion feature and deferred financing costs under our previous credit facility.  In addition, there was a 
$1.0 million increase in miscellaneous income, partially offset by a $3.7 million increase in realized losses on 
foreign currency remeasurement for the year ended December 31, 2017 as compared to the same period in 2016.

Income taxes reflected a provision of $15.8 million for the year ended December 31, 2017 as compared to a 

provision of $3.7 million for the same period in 2016. The higher effective tax rate in 2017 was primarily due to the 
improved operating results in China and Turkey and the mix of earnings among jurisdictions year over year. 

Net income for the year ended December 31, 2017 was $38.7 million, as compared to $27.0 million in the 

same period in 2016. The increase was primarily due to the reasons set forth above.

Net income attributable to preferred stockholders was $5.5 million during the year ended December 31, 2016 
and there was none in the 2017 period as following our IPO in July 2016, all of the previously outstanding preferred 
shares were converted into common shares.

Net income attributable to common stockholders increased to $38.7 million during the year ended 

December 31, 2017 from $21.6 million in the same period in 2016. This increase was primarily due to the improved 
operating results discussed above as well as the decrease in the net income attributable to preferred stockholders. 
Diluted earnings per share for the year ended December 31, 2017 was $1.11 compared to $1.22 for the year ended 
December 31, 2016.

U.S. Segment

Net sales in the year ended December 31, 2017 decreased by $0.8 million or 0.4% to $191.0 million compared 

to $191.9 million in the same period in 2016. Net sales of wind blades increased to $164.9 million during the year 
ended December 31, 2017 from $163.9 million in the same period of 2016. The increase was primarily due to a 7% 
increase in the number of wind blades produced in the year ended December 31, 2017 as compared to the same 
period in 2016, mostly offset by a decline in the average sales prices of the same wind blade models delivered in
both periods as a result of savings in raw material costs, a portion of which we share with our customers. Net sales
from the manufacturing of precision molding and assembly systems during the year ended December 31, 2017 were 
$8.4 million compared to $17.7 million during the same period in 2017. The decrease was the result of our 
customers requiring less precision molding and assembly systems from our Rhode Island facility during the year 
ended December 31, 2017 as compared to the same period in 2016. Additionally, there was a $7.5 million increase 
in non-wind related net sales, primarily transportation sales, during the year ended December 31, 2017 as compared 
to 2016.

The loss from operations for the year ended December 31, 2017 was $33.2 million as compared to $19.2 million 

in the same period in 2016. These amounts include corporate general and administrative costs of $40.4 million and 
$33.9 million for the years ended December 31, 2017 and 2016, respectively. The increase in the corporate general 
and administrative costs was primarily driven by additional costs incurred related to the implementation of Topic 
606, costs related to the Sarbanes-Oxley Act and our secondary public offering, increased personnel costs from 
filling our key global positions to support our growth and diversification strategy, partially offset by a $2.3 million 
decrease in share-based compensation costs during the year ended December 31, 2017 as compared to the same
period in 2016. The operating results were also unfavorably impacted by slightly lower gross profit on wind blades 
delivered during the year ended December 31, 2017 as compared to the 2016 period as well as the lower precision 
molding and assembly system volume discussed above during the year ended December 31, 2017 as compared to
the same period in 2016.  

Asia Segment

Net sales in the year ended December 31, 2017 increased by $63.0 million or 20.3% to $372.5 million
compared to $309.6 million in the same period in 2016. Net sales of wind blades were $346.2 million in the year 
ended December 31, 2017 as compared to $287.4 million in the same period in 2016. The increase was primarily the 
result of a 30% increase in the number of wind blades produced during the year ended December 31, 2017 compared 
to the same period in 2016. These increases were partially offset by a change in the mix of wind blade models sold, 

64

lower average sales prices of the same wind blades sold in both periods due to savings in raw material costs, a 
portion of which we share with our customers. Net sales from the manufacturing of precision molding and assembly 
systems during the year ended December 31, 2017 were $18.4 million compared to $17.8 million during the same 
period in 2016. The impact of the fluctuating U.S. dollar against the Chinese Renminbi had an unfavorable impact of 
0.8% on net sales during the year ended December 31, 2017 as compared to the same period in 2016.  

Income from operations in the Asia segment for the year ended December 31, 2017 was $76.3 million as 
compared to $67.1 million in the same period in 2016. In addition to the factors noted above, the increase in income 
from operations reflects higher gross margins on wind blade sales driven by operating efficiencies as well as lower 
overhead costs in the 2017 period as compared to 2016. The fluctuating U.S. dollar against the Chinese Renminbi 
had a favorable impact of 1.5% on cost of goods sold for the year ended December 31, 2017 as compared to the 
comparable 2016 period. 

Mexico Segment

Net sales in the year ended December 31, 2017 increased by $78.5 million or 61.4% to $206.6 million 
compared to $128.0 million in the same period in 2016. The increase reflects an increase in wind blade volume at 
our first Mexico plant and the beginning of wind blade production in our second and third plants, partially offset by 
lower average sales prices of wind blades delivered in both periods. 

Income from operations in the Mexico segment for the year ended December 31, 2017 was $14.4 million as 

compared to $10.1 million in the same period in 2016. The increase was largely driven by the increase in wind blade 
volume in the 2017 period as compared to 2016 and operating efficiencies at our first Mexico plant, as well as from 
savings in raw material costs, partially offset by the startup losses incurred at two of our new Mexico facilities. The 
fluctuating U.S. dollar against the Mexican Peso on cost of goods sold for the year ended December 31, 2017 as 
compared to the comparable 2016 period was not significant. 

EMEAI Segment

Net sales during the year ended December 31, 2017 increased by $45.5 million or 32.6% to $185.1 million 
compared to $139.6 million in the same period in 2016. The increase was driven by the beginning of wind blade 
production in our second Turkey plant, partially offset by a 24% decrease in wind blade volume at our first Turkey 
plant as a result of GE Wind only purchasing the minimum volume required under its supply agreement after its 
decision to not renew its supply agreement with us beyond 2017. As a result, we accelerated production for GE in 
2017 and completed 100% of GE volume by the end of June 2017 to enable us to accelerate the transition of those 
manufacturing lines to two new manufacturing lines for another customer in the second half of 2017. Other items 
having a favorable impact on net sales include the mix of wind blades sold during the period as well as overall 
higher average sales prices of wind blades delivered due to the beginning of wind blade production in our second 
Turkey plant in the period as compared to 2016. The fluctuating U.S. dollar against the Euro had a favorable effect 
on net sales of 1.8% for the year ended December 31, 2017 as compared to the comparable 2016 period.

The income from operations in the EMEAI segment for the year ended December 31, 2017 was $12.6 million 

as compared to a loss of $5.1 million in the same period in 2016. The increase was primarily driven by the wind 
blade production in our second Turkey plant, improved operating efficiencies at our first Turkey plant, savings in 
raw material costs and a warranty reserve provided in 2016 related to one of its customers to resolve a potential 
warranty claim arising from wind blades primarily manufactured in 2014. The fluctuation of the U.S. dollar relative 
to the Turkish Lira and Euro had a 5.4% favorable impact on cost of goods sold in the year ended December 31, 
2017 as compared to 2016.  

LIQUIDITY AND CAPITAL RESOURCES

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 and debt service 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 

65

facilities and from proceeds received from the issuance of stock. As discussed below, during 2017 we completed a 
secondary public offering of common stock for which we received no proceeds and during 2016 we completed an 
initial public offering of common stock for which we received net proceeds of $67.2 million. During the years ended 
December 31, 2018, 2017 and 2016, we had net repayments of financing arrangements of $8.9 million, $8.1 million 
and $15.4 million, respectively. As of December 31, 2018 and 2017, we had $138.5 million and $123.6 million in 
outstanding indebtedness, excluding debt issuance costs, respectively. As of December 31, 2018, we had an 
aggregate of $79.8 million of remaining capacity and $77.2 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 as well as the increased 
level of transitions. 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. 

In July 2016, we completed an IPO of 7,187,500 shares of our common stock at a public offering price of 
$11.00 per share, which included 937,500 shares issued pursuant to the underwriters’ over-allotment option. We 
received $67.2 million in proceeds, net of underwriting discounts and offering expenses and intend to use the net 
proceeds from the public offering for our working capital and other general corporate purposes, including financing 
existing manufacturing operations, expansion in existing and new geographies and repayment of a customer 
advance. Immediately prior to the closing of the IPO, all shares of the then-outstanding redeemable preferred shares 
converted into an aggregate of 21,110,204 shares of common stock and the redeemable preferred share warrants 
were converted on a net issuance basis into 120,923 shares of common stock. In addition, concurrent with the 
closing of the IPO, certain subordinated convertible promissory notes in the aggregate principal and interest amount 
of $11.9 million were converted into an aggregate of 1,079,749 shares of common stock at the public offering price 
of $11.00 per share. Prior to the IPO, in July 2016 we also consummated a 360-for-1 forward stock split of our 
common stock.

In May 2017, we completed a secondary public offering of 5,075,000 shares of our common stock at a price of 

$16.35 per share, which included 575,000 shares issued pursuant to the underwriters’ option to purchase additional 
shares. All of the shares were sold by existing stockholders and certain of our executive officers. The selling 
stockholders received all of the net proceeds of $78.8 million from the secondary public offering. We did not sell 
any shares and did not receive any of the proceeds from the offering and the costs paid by us in connection with the 
offering of $0.8 million were recorded in general and administrative costs in the accompanying consolidated income 
statement.

We anticipate that any new facilities and future facility expansions will be funded through cash flows from 
operations, the proceeds of our IPO, the incurrence of other indebtedness and other potential sources of liquidity.

At December 31, 2018 and 2017, we had unrestricted cash, cash equivalents and short-term investments 
totaling $85.3 million and $148.1 million, respectively. The December 31, 2018 balance includes $31.6 million of 
cash located outside of the United States, including $28.9 million in China, $1.0 million in Turkey and $1.7 million 
in Mexico. The December 31, 2017 balance includes $49.2 million of cash located outside of the United States, 
including $46.3 million in China, $0.7 million in Turkey and $2.2 million in Mexico. 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 the People’s Republic of China, including retained earnings as determined under Chinese-
statutory accounting requirements. Until 50% ($21.6 million) of registered capital is contributed to a surplus reserve, 
our Chinese 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 Chinese operations can pay dividends equal 
to 100% of after-tax profit assuming other conditions are met. At December 31, 2018, the amount of the surplus 
reserve fund was $6.5 million.

Net cash used in operating activities totaled $3.3 million for the year ended December 31, 2018 and was 
primarily the result of a $36.2 million decrease in working capital and $6.6 million of other non-cash items, mostly 
offset by non-cash depreciation and amortization charges totaling $26.4 million, share-based compensation costs of 
$7.8 million and net income of $5.3 million. The key components of the decrease in working capital include a $59.2 
million increase in accounts receivable, a $7.9 million increase in contract assets and labilities, a $5.2 million
increase in other noncurrent assets, and a $2.0 million decrease in other noncurrent liabilities. This was partially 
offset by a $32.3 million increase in accounts payable and accrued expenses and a $6.3 million increase in accrued 
warranty. The working capital changes in contract assets and liabilities, accounts receivable, accounts payable and 
accrued expenses and accrued warranty are primarily the result of the timing of production in the year ended 
December 31, 2018.

Net cash provided by operating activities totaled $74.6 million for the year ended December 31, 2017 and was 

primarily the result of net income of $38.7 million, non-cash depreciation and amortization charges totaling $21.7
million, share-based compensation costs of $7.1 million as well as the net changes in working capital. The key
components of the working capital changes include a $51.5 million increase in accounts payable and accrued 
expenses, a $9.3 million increase in accrued warranty, a $3.2 million decrease in prepaid expenses and other current 
assets, and a $2.8 million decrease in other noncurrent assets. This was partially offset by a $54.2 million increase in
accounts receivable, a $4.6 million decrease in other noncurrent liabilities, and a $4.4 million increase in contract 
assets and liabilities. The working capital changes in contract assets and liabilities, accounts receivable, accounts 
payable and accrued expenses and accrued warranty are primarily the result of the timing of production in the year 
ended December 31, 2017.

Net cash provided by operating activities totaled $59.8 million for the year ended December 31, 2016 and was 

primarily the result of net income of $27.0 million, non-cash depreciation and amortization charges totaling 
$13.2 million, share-based compensation costs of $9.9 million and other non-cash items of $3.0 million, as well as
the net changes in working capital. The key components of the working capital change include a $17.4 million 
increase in accounts payable and accrued expenses, a $6.7 million increase in accrued warranty, and a $5.6 million 
decrease in accounts receivable. This was partially offset by a $17.2 million increase in contract assets and liabilities
and a $3.7 million increase in other noncurrent assets. The working capital changes in contract assets and liabilities,
accounts receivable, accounts payable and accrued expenses and accrued warranty are primarily the result of the 
timing of production in the year ended December 31, 2016.

Net cash flows used in investing activities totaled $52.7 million, $44.0 million and $30.5 million in the years
ended December 31, 2018, 2017 and 2016, respectively, driven primarily by capital expenditures for new facilities 
and expansion or improvements at existing facilities. The capital expenditures for the year ended December 31, 
2018 primarily related to our new wind blade plants in Matamoros, Mexico and Yangzhou, China, the expansion 
and improvements at our Taicang, China facility, our second wind blade plant in Turkey, our second facility in 
Newton, Iowa and costs to enhance our information technology systems. The capital expenditures for the year ended 
December 31, 2017 primarily related to the construction and outfitting of our second and third wind blade plants in 
Mexico and our second wind blade plant in Turkey, the expansion and improvements at certain of our existing wind 
blade plants and costs at our corporate office to enhance our information technology systems. The capital 
expenditures for the year ended December 31, 2016 primarily related to the plant build outs of three new wind blade
facilities, two in Mexico and one in Turkey. The above capital expenditure amounts do not include the amounts 
which we financed primarily through capital leases totaling $22.0 million, $6.2 million and $10.0 million in the 
years ended December 31, 2018, 2017 and 2016, respectively. 

We anticipate fiscal year 2019 capital expenditures of between $95 million to $100 million and we estimate 

that the cost that we will incur after December 31, 2018 to complete our current projects in process will be 
approximately $9.7 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 new manufacturing facilities in Chennai, India, Yangzhou, China and our tooling 
facility in Juárez, Mexico and the continued investment in our existing China, Mexico and Turkey wind blade
facilities and costs to enhance our information technology systems.

Net cash flows used in financing activities for the year ended December 31, 2018 and 2017 totaled $7.7
million and $8.4 million, respectively. The net cash flows provided by financing activities totaled $51.8 million for 
the year ended December 31, 2016. Net cash used in financing activities for the year ended December 31, 2018 
primarily reflects the net repayment of growth-related debt and the repurchase of common stock associated with 
taxes on the vesting of share-based awards, mostly offset by the net proceeds from revolving and term loans and the 
proceeds from the exercise of stock options. Net cash flows used in financing activities for the year ended

Description of Our Indebtedness 

Refer to Note 12 - 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 for a description of our 
indebtedness.

Other Contingencies

Other than as noted in “Legal Proceedings” included in Part I, Item 3 of this Annual Report on Form 10-K as 

of December 31, 2018 and 2017, we were not involved in any material litigation. In the future, however, we may 
become involved in various claims and legal actions arising in the ordinary course of business which may have a 
material adverse effect on our consolidated financial position, results of operations or liquidity.

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, 2018 and 2017, we had accrued warranty reserves totaling $36.8 million and $30.4 million, 
respectively. The increase in the accrued warranty reserve during 2018 was primarily due to the accrual for sales 
during the year, partially offset by reductions in the reserve due to the cost of warranty services provided during the 
year and the expiration of the warranty period for specific products.

Other than as noted in “Legal Proceedings” included in Part I, Item 3 of this Annual Report on Form 10-K as 

of December 31, 2018 and 2017, we had no material operating expenditures for environmental matters, including 
government imposed remedial or corrective actions, during the years ended December 31, 2018, 2017 and 2016.

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 operating lease arrangements and the 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 consolidated financial 
statements and related notes.

Our Mexico segment has an existing accounts receivable assignment agreement with a financial institution 
under which the financial institution buys, on a non-recourse basis, the accounts receivable amounts related to one of 
our Mexico segment’s customers at a discount calculated based on an effective annual rate of LIBOR plus 2.75%. 

In September 2018, our U.S. and Mexico segments entered into an accounts receivable assignment agreement 

with a financial institution. Under this agreement, the financial institution buys, on a non-recourse basis, the 
accounts receivable amounts related to one of our U.S. (Iowa location) and Mexico segment’s customers at a 
discount calculated based on LIBOR plus 0.55%. 

In the fourth quarter of 2018, our EMEAI segment entered into an accounts receivable assignment agreement 

with a financial institution. Under this agreement, the financial institution may buy, on a non-recourse basis, up to 
15.0 million Euro (approximately $17.2 million as of December 31, 2018) of the accounts receivable amounts 
related to one of our EMEAI segment’s customers at a discount calculated based on EURIBOR plus 2.65%. 

In the fourth quarter of 2018, our EMEAI segment entered into an accounts receivable assignment agreement 

with a financial institution. Under this agreement, the financial institution buys, on a non-recourse basis, the 
accounts receivable amounts related to one of our EMEAI segment’s customers at a discount calculated based on 
EURIBOR plus 0.75%. 

69

As the receivables are purchased by the financial institutions under the agreements as described in the
preceding paragraphs, the receivables were removed from our balance sheet. During the year ended December 31,
2018, $214.6 million of receivables were sold under the accounts receivable assignment agreements described 
above.

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. 

To determine the proper revenue recognition method for each long-term contract, we evaluate whether the
original contract should be accounted for as one or more performance obligations. This evaluation requires judgment 
and the decisions reached could change the amount of revenue and gross profit recorded in a given period. As most 
of our contracts contain multiple performance obligations, we allocate the total transaction price to each 
performance obligation based on the estimated relative standalone selling prices of the promised goods or services 
underlying each performance obligation. 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; therefore, we 
allocate the total transaction price under our contracts with multiple performance obligations using the contractually 
stated prices, as these prices represent the relative standalone selling price based on an expected cost plus margin
model.  

70

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.  In addition, the customer does not have 
return or refund rights for items produced that conform to the specifications included in the contract. Because 
control transfers over time, revenue is recognized based on the extent of progress towards the completion of the 
performance obligation. We use the cost-to-cost input measure of progress for our contracts as this method provides 
the best representation of the production progress towards satisfaction of the performance obligation as the materials 
are distinct to the product being manufactured because of customer specifications provided for in the contract, the 
costs incurred are proportional to the progress towards completion of the product, and the products do not involve 
significant pre-fabricated component parts. 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 contract 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 
significant judgments and estimates relating to the total consideration to be received and the expected total costs to 
complete the performance obligation.  The judgments and estimates relating to the total consideration to be received 
include the amount of variable consideration as our contracts typically provide the customer with a range of 
production output options from guaranteed minimum volume obligations to the production capacity of the facility, 
and customers will provide periodic non-cancellable commitments for the number of wind blades to be produced 
over the term of the agreement.  We use historical experience, customer commitments and forecasted future 
production based on the capacity of the plant to estimate the total revenue to be received to complete the 
performance obligation.  In addition, the amount of revenue per unit produced may vary based on the costs of 
production of the wind blades as we may be able to change the price per unit based on changes in the cost of 
production.  Further, some of our contracts provide opportunities for us to share in labor and material cost savings as 
well as absorb some additional costs as an incentive for more efficient production, both of which impact the margin 
realized on the contract and ultimately the total amount of revenue to be recognized.  Additionally, certain of our 
customer contracts provide for concessions by us for missed production deadlines.  

We estimate variable consideration at the most likely amount to which we expect to be entitled. We include 

estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative 
revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. 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.

Our contracts may be modified to account for changes in specifications of products and changing requirements 

(e.g. transitions). If the contract modifications are for goods or services that are not distinct from the existing 
contract, they are accounted for as if they were part of the original contract. The effect of a contract modification on 
the transaction price and the measure of progress for the performance obligation to which it relates is recognized as 
an adjustment to revenue on a cumulative catch-up basis. If contract modifications are for goods and services that 
are distinct from the existing contract and increases the amount of consideration reflecting the standalone sale price 
of the additional goods or services, then the contract modification is accounted for as a separate contract and is 
evaluated for one or more performance obligations.  

Each reporting period, we evaluate the progress towards satisfaction of each performance obligation based on 
any contract modifications that have occurred, cost incurred to date, and an estimate of the expected future revenue 
and costs to be incurred to complete the performance obligation. Based on this analysis, any changes in estimates of 
revenue, cost of sales, contract assets and liabilities and the related impact to operating income are recognized on a 
cumulative catch-up basis, which recognizes in the current period the cumulative effect of the changes on current 
and prior periods based on the percentage of completion of the performance obligation.

Wind blade pricing is based on annual commitments of volume as established in our customer contracts and 

orders less than committed volume may result in a higher price per wind blade to our customers. Orders in excess of 
annual commitments may result in discounts to our customers from the contracted price for the committed volume. 
Our customers typically provide periodic purchase orders with the price per wind blade given the current cost of the 
bill of materials, labor requirements and volume desired.  We record an allowance for expected utilization of early 
payment discounts which are reported as a reduction of the related revenue. 

71

Precision molding and assembly systems included in a customer’s contract are based upon the specific 

engineering requirements and design determined by the customer and are specific to the wind blade design and 
function desired. From the customer’s engineering specifications, a job cost estimate is developed along with a 
production plan, and the desired margin is applied based on the location the work is to be performed and complexity 
of the customer’s design. Precision molding and assembly systems are generally built to produce wind blades which 
may be manufactured by us in production runs specified in the customer contract.

Contract assets 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 and invoices are due based on each customers negotiated payment terms, 
which range from 15 to 90 days.  We apply the practical expedient that allows us to exclude payment terms under 
one year from the transfer of a promised good or service from consideration of a significant financing component in 
its contracts. With regards to the production of precision molding and assembly systems, our contracts generally call 
for progress payments to be made in advance of production. Generally, payment is made at certain percentage of 
completion milestones with the final payment due upon delivery to the manufacturing facility. These progress 
payments are recorded within contract liabilities as current liabilities in the consolidated balance sheets and are 
reduced as we record revenue over time.  

Our customers may request, in situations where they do not have space available to receive products or do not 
want to take possession of products immediately for other reasons, that their finished products be stored by us in one 
of our facilities. Most of our contracts provide for a limited number of wind blades to be stored during the period of 
the contract with any additional wind blades stored subject to additional storage fees, which are included in the wind 
blade performance obligation revenue.  

Revenue related to non-recurring engineering and freight services provided under our customer contracts is 
recognized at a point in time following the transfer of control of the promised services to the customer. Customers 
usually pay the carrier directly for the cost of shipping associated with items produced.  When we pay the shipping 
costs, we apply the practical expedient that allows us to account for shipping and handling as a fulfillment costs and 
include the revenue in the associated performance obligation and the costs are included in cost of goods sold.

Taxes assessed by a governmental authority that are both imposed on and concurrent with specific revenue-

producing transactions, that are collected by us from a customer, are excluded from revenue.

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 in the evaluation 
of our tax positions.

Additionally, we record the estimated future tax effects of temporary differences between the tax basis of 

assets and liabilities and amounts reported in the accompanying consolidated balance sheets, as well as operating 
loss and tax credit carryforwards. We then assess the likelihood that our deferred income tax assets will be realized 
by evaluating all available positive and negative evidence in order to determine if it is more-likely-than-not that the 
deferred tax assets will be realized. To the extent we believe that the realization of our deferred tax assets is not 
more-likely-than-not, we are required to establish a valuation allowance. In doing so we considered our recent 
operating history, taxpaying history and future reversals of deferred tax liabilities based upon future operating 
projections. Historically, as a result of cumulative losses in the United States, we determined that a valuation 
allowance for all of our U.S. deferred tax assets was appropriate. During the third quarter of 2018, we reversed a 
portion of the United States valuation allowance, based on the available evidence at that time. We periodically 
evaluate all available positive and negative evidence regarding the future recoverability of our deferred tax assets 
and, when we determine that the recoverability of deferred tax assets meets the criteria of more-likely-than-not, we 
reduce the valuation allowance against our deferred tax assets. The effect of a change in judgment concerning the 
realizability of deferred tax assets is included in provision for income taxes. 

72

As of December 31, 2018, we have U.S. federal NOLs of approximately $25.8 million, state NOLs of 

approximately $118.5 million, foreign NOLs of approximately $14.6 million and foreign tax credits of 
approximately $1.9 million available to offset future taxable income in the U.S. and China. We also have tax 
incentives available to reduce approximately $0.3 million of future taxes to be incurred by our original Turkey 
facility. 

On December 22, 2017, President Trump signed into law Tax Reform, 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, net operating loss deduction limitations, tax on GILTI earned by foreign corporate 
subsidiaries, the BEAT, and a deduction for FDII.  

At December 31, 2018, we completed the accounting for the enactment-date income tax effects of Tax 
Reform, which resulted in an immaterial impact to the 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. Additionally, we have 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. decreased from 35% to 21% beginning in January 2018, while the tax rates in China and 
Mexico are 25% and 30%, respectively. During the fourth quarter of 2017, Turkey also modified its statutory 
corporate income tax rate from 20% to 22% for 2018, 2019, and 2020. Our second Turkey facility is located in a 
tax-free zone and is not subject to income taxes for its earnings recognized from its manufacturing activities. 

Warranty Expense. As discussed above, 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. We 
accrued $15.0 million during 2016 to cover the aggregate costs associated with the agreement that we entered into 
with Nordex to settle potential claims relating to a wind blade failure that occurred in 2015 and certain alleged 
defects with respect to that wind blade and certain other wind blades that were primarily manufactured in 2014. See 
“—Other Contingencies” above for more information. Except for these costs, we have not experienced other 
material warranty expenses beyond the provision described above in the years ended December 31, 2018, 2017 and 
2016. However, changes in warranty reserves could have a material effect on our consolidated financial statements.

Recent Accounting Pronouncements

For a discussion of recent accounting pronouncements, see Note 1 – Summary of Operations and Significant 
Accounting Policies of the Notes to Consolidated Financial Statements in Part II, Item 8 of this Annual Report on 
Form 10-K.

Jumpstart Our Business Startups Act of 2012

On April 5, 2012, the JOBS Act was enacted. Section 107 of the JOBS Act provides that an “emerging growth 

company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act 
for complying with new or revised accounting standards. We intend to take advantage of certain exemptions from 
various reporting requirements that are applicable to other public companies that are not emerging growth 
companies including not being required to comply with the auditor attestation requirements of Section 404(b) of the 
Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and 
proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive 
compensation and stockholder approval of any golden parachute payments not previously approved. We may take 
advantage of these reporting exemptions until we are no longer an emerging growth company. We will remain an 
emerging growth company until the earliest of (i) the last day of the fiscal year in which we have total annual gross 
revenues of $1.07 billion or more; (ii) the last day of our fiscal year following the fifth anniversary of the date of the 
completion of our IPO; (iii) the date on which we have issued more than $1.0 billion in nonconvertible debt during 
the previous three years or (iv) the date on which we are deemed to be a “large accelerated filer” under the rules of 
the SEC.

We expect to no longer qualify as an emerging growth company at some point during 2019; therefore, we will 

no longer be able to take advantage of the exemptions provided for the various reporting requirements described 
above. 

Under the JOBS Act, emerging growth companies can also delay adopting new or revised accounting 
standards until such time as those standards apply to private companies. We have irrevocably elected not to avail 
ourselves of this exemption from new or revised accounting standards and, therefore, will be subject to the same 
new or revised accounting standards as other public companies that are not emerging growth companies.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to market risk in the ordinary course of our business. These market risks are principally 

limited to changes in foreign currency exchange rates and commodity prices. We currently do not hedge our 
exposure to these risks.

Foreign Currency Risk. We conduct international operations in China, Mexico, Turkey and Denmark. Our 
results of operations are subject to both currency transaction risk and currency translation risk. We incur currency 
transaction risk whenever we enter into either a purchase or sale transaction using a currency other than the local 
currency of the transacting entity. With respect to currency translation risk, our financial condition and results of 
operations are measured and recorded in the relevant domestic currency and then translated into U.S. dollars for 
inclusion in our consolidated financial statements. In recent years, exchange rates between these foreign currencies 
and the U.S. dollar have fluctuated significantly and may do so in the future. A hypothetical change of 10% in the 
exchange rates for the countries above would have resulted in a change to income from operations of approximately 
$7.4 million and $8.9 million for the years ended December 31, 2018 and 2017, respectively.

Commodity Price Risk. We are subject to commodity price risk under agreements for the supply of our raw 
materials. We have not hedged, nor do we intend to hedge, our commodity price exposure. We generally lock in 
pricing for our key raw materials for 12 months which protects us from price increases within that period. As many 
of our raw material supply agreements have meet or release clauses, if raw materials prices go down, we are able to 
benefit from the reductions in price. We believe that this adequately protects us from increases in raw material prices 
and also enables us to take full advantage of decreases.

Resin and resin systems are the only commodities for which we do not have fixed pricing. Approximately 
30% of the resin and resin systems we use is purchased under contracts controlled by two of our customers and 

74

therefore they receive/bear 100% of any increase or decrease in resin costs further limiting our exposure to price 
fluctuations. We believe that a 10% change in the price of resin and resin systems for the customers in which we are 
exposed to fluctuating prices would have had an impact to income from operations of approximately $7.6 million 
and $13.3 million for the years ended December 31, 2018 and 2017, respectively. Furthermore, this amount does not 
include the portion of any increase or decrease that would be shared with our customers under our long-term supply 
agreements, which is generally 70%.

Interest Rate Risk. As of December 31, 2018, our EMEAI segment has one general credit agreement with a 

Turkish financial institution outstanding which is tied to EURIBOR. This agreement contains collateralized 
financing of capital expenditures. As of December 31, 2018, there was $12.2 million of collateralized financing of 
capital expenditures outstanding. In addition, as of December 31, 2018, our Credit Agreement includes interest on 
the unhedged principal amount of $15.4 million which is tied to LIBOR. The one EMEAI general credit agreement 
and our Credit Agreement noted above are the only variable rate debt that we had outstanding as of December 31, 
2018 as all remaining working capital loans, accounts receivable financing and capital lease obligations are fixed 
rate instruments and are not subject to fluctuations in interest rates. Due to the relatively low LIBOR and EURIBOR 
rates in effect as of December 31, 2018, a 10% change in the LIBOR or EURIBOR rate would not have had a 
material impact on our future earnings, fair values or cash flows.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to provide reasonable assurance that 
information required to be disclosed in our reports under the Exchange Act is recorded, processed, summarized, and 
reported within the time period specified in the SEC’s rules and forms and that such information is accumulated and 
communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as 
appropriate, to allow timely decisions regarding required disclosure.

As required by Rule 13a-15(b) promulgated under the Exchange Act, our management, with the participation 

of our Chief Executive Officer and Chief Financial Officer, evaluated the design and operating effectiveness as of 
December 31, 2018 of our disclosure controls and procedures, as defined in Rule 13a-15(e) promulgated under the 
Exchange Act. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our 
disclosure controls and procedures were effective as of December 31, 2018.

Management’s Report on Internal Control Over Financial Reporting and Attestation Report of the 
Registered Public Accounting Firm

As required by Rules 13a-15(f) promulgated under the Exchange Act, our management is responsible for 
establishing and maintaining adequate internal control over financial reporting to provide reasonable assurance 
regarding the reliability of our financial reporting and the preparation of financial statements for external purposes in 
accordance with U.S. generally accepted accounting principles.  Management assessed the effectiveness of our 
internal control over financial reporting as of December 31, 2018.  Management based its assessment on criteria 
established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations 
of the Treadway Commission (COSO). Management's assessment included evaluation of elements such as the 
design and operating effectiveness of key financial reporting controls, process documentation, accounting policies 
and our overall control environment. Based on this assessment, management has concluded that our internal control 
over financial reporting was effective as of December 31, 2018 to provide reasonable assurance regarding the 
reliability of financial reporting and the preparation of financial statements for external reporting purposes in 
accordance with U.S. generally accepted accounting principles. We reviewed the results of management's 
assessment with the Audit Committee of our Board of Directors.

This Annual Report on Form 10-K does not include an attestation report of our registered public accounting 

firm on our internal control over financial reporting due to an exemption established under the JOBS Act for 
“emerging growth companies.” 

Changes in Internal Control Over Financial Reporting

As a result of the adoption of Topic 606, we have re-evaluated and established new internal controls related to 
revenue recognition. We are also currently updating our enterprise risk planning systems to accommodate Topic 606 
and will continue to evaluate such internal controls.

Except as noted above, there have not been any other changes in our internal control over financial reporting 

during the three months ended December 31, 2018, that have materially affected, or are reasonably likely to 
materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors 
TPI Composites, Inc.:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of TPI Composites, Inc. and subsidiaries (the 
Company) as of December 31, 2018 and 2017, the related consolidated statements of income, comprehensive 
income (loss), changes in stockholders’ equity (deficit), and cash flows for each of the years in the three-year period 
ended December 31, 2018, and the related notes (collectively, the consolidated financial statements). In our opinion, 
the consolidated financial statements present fairly, in all material respects, the financial position of the Company as 
of December 31, 2018 and 2017, and the results of its operations and its cash flows for each of the years in the 
three-year period ended December 31, 2018, in conformity with U.S. generally accepted accounting principles.

Adoption of New Accounting Pronouncement

As discussed in Note 1 to the consolidated financial statements, the Company has changed its method of accounting 
for revenue in 2018, 2017, and 2016 due to the adoption of ASC Topic 606, Revenue from Contracts with 
Customers.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is 
to express an opinion on these consolidated financial statements based on our audits. We are a public accounting 
firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to 
be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable 
rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and 
perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of 
material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to 
perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an 
understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the 
effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial 
statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures 
included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial 
statements. Our audits also included evaluating the accounting principles used and significant estimates made by 
management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that 
our audits provide a reasonable basis for our opinion.

We have served as the Company’s auditor since 2008.

Notes to Consolidated Financial Statements

Note 1. Summary of Operations and Significant Accounting Policies

(a) Description of Business 

TPI Composites, Inc. is the holding company that conducts substantially all of its business operations through 

its direct and indirect subsidiaries (collectively, the Company or we). The Company was founded in 1968 and has 
been producing composite wind blades since 2001. The Company’s knowledge and experience of composite 
materials and manufacturing originates with its predecessor company, Tillotson Pearson Inc., a leading manufacturer 
of high-performance sail and powerboats along with a wide range of composite structures used in other industrial 
applications. Following the separation from the boat building business in 2004, the Company reorganized in 
Delaware as LCSI Holding, Inc. and then changed its corporate name to TPI Composites, Inc. in 2008. Today, the 
Company is headquartered in Scottsdale, Arizona and has expanded its global footprint to include domestic facilities 
in Newton, Iowa; Fall River, Massachusetts; Warren, Rhode Island and Santa Teresa, New Mexico and international 
facilities in Dafeng, China; Taicang Port, China; Taicang City, China; Juárez, Mexico; Matamoros, Mexico; Izmir, 
Turkey; Kolding, Denmark and Chennai, India.

(b) Basis of Presentation

We divide our business operations into four geographic operating segments—the United States (U.S.), Asia, 

Mexico and Europe, the Middle East, Africa and India (EMEAI), as follows:

•

•

•

•

Our U.S. segment includes (1) the manufacturing of wind blades at our Newton, Iowa plant, (2) the 
manufacturing of precision molding and assembly systems used for the manufacture of wind blades at 
our Warren, Rhode Island facility, (3) the manufacturing of composite solutions for the transportation 
industry, which we also conduct at our existing Rhode Island facility as well as at our Fall River, 
Massachusetts facility and at a second manufacturing facility in Newton, Iowa which commenced 
operations in the second quarter of 2018, (4) wind blade inspection and repair services in North 
America, (5) our advanced engineering center in Kolding, Denmark, which provides technical and 
engineering resources to our manufacturing facilities and (6) our corporate headquarters, the costs of 
which are included in general and administrative expenses. 

Our Asia segment includes (1) the manufacturing of wind blades at our facilities in Taicang Port, China; 
Dafeng, China and Yangzhou, China, the latter of which we expect to commence operations in the first 
quarter of 2019, (2) the manufacturing of precision molding and assembly systems at our Taicang City, 
China facility and (3) wind blade inspection and repair services. 

Our Mexico segment manufactures wind blades from three facilities in Juárez, Mexico and a facility in 
Matamoros, Mexico at which we commenced operations in the third quarter of 2018. In November 
2018, we entered into a new lease agreement with a third party for a new precision molding and 
assembly systems manufacturing facility in Juárez, Mexico and we expect to commence operations at 
this facility in the first quarter of 2019. This segment also performs wind blade inspection and repair 
services. 

Our EMEAI segment manufactures wind blades from two facilities in Izmir, Turkey and also performs 
wind blade inspection and repair services. In February 2019, we entered into a new lease agreement 
with a third party for a new manufacturing facility that will be built near Chennai, India and we expect 
to commence operations at this facility in the first half of 2020.

The accompanying consolidated financial statements include the accounts of TPI Composites, Inc. and all 

majority owned subsidiaries. All significant intercompany transactions and balances have been eliminated.

As previously announced, effective January 1, 2018, we adopted Accounting Standards Update (ASU) 2014-

09, Revenue from Contracts with Customers, (Topic 606) using the full retrospective method as further described in 
Recently Issued Accounting Pronouncements - Revenue from Contracts with Customers and Note 2, Revenue from 
Contracts with Customers. All amounts and disclosures set forth in this Annual Report on Form 10-K reflect the 
adoption of Topic 606 and may differ, as disclosed in these notes, from amounts previously reported in our 
December 31, 2017 consolidated balance sheet and our consolidated income and cash flow statements for the years 

F-8

TPI COMPOSITES, INC. AND SUBSIDIARIES 

Notes to Consolidated Financial Statements

ended December 31, 2017 and 2016. See Note 19, Adjustments to Previously Reported Financial Statements from 
the Adoption of an Accounting Pronouncement, for a further discussion of the adoption of Topic 606, including the 
impact on our previously reported consolidated financial statements.

(c) Public Offerings and Stock Split

In July 2016, we completed an initial public offering (IPO) of 7,187,500 shares of our common stock at a 
price of $11.00 per share, which included 937,500 shares issued pursuant to the underwriters’ over-allotment option. 
Certain of our existing stockholders, a non-employee director and executive officers purchased an aggregate of 
1,250,000 shares of our common stock in the IPO included in the total issuance above. The net proceeds from the 
IPO were $67.2 million after deducting underwriting discounts and offering expenses. Immediately prior to the 
closing of the IPO, all shares of the then-outstanding redeemable preferred shares converted into an aggregate 
of 21,110,204 shares of our common stock and the redeemable preferred share warrants converted on a net issuance 
basis into 120,923 shares of our common stock. In addition, concurrent with the closing of the IPO, certain 
subordinated convertible promissory notes in the aggregate principal and interest amount of $11.9 million were 
converted into 1,079,749 shares of our common stock at the public offering price of $11.00 per share.

Prior to the IPO, in July 2016, we amended our amended and restated certificate of incorporation to effect a 

360-for-1 forward stock split of our common stock. As a result of the stock split, we have adjusted the share 
amounts authorized and issuable under the share-based compensation plans. All share and per share common stock 
information referenced throughout the consolidated financial statements and notes thereto have been retroactively 
adjusted to reflect this stock split. The stock split did not cause an adjustment to the par value of the authorized 
shares of our common stock.

In May 2017, we completed a secondary public offering of 5,075,000 shares of our common stock at a price of 

$16.35 per share, which included 575,000 shares issued pursuant to the underwriters’ option to purchase additional 
shares. All of the shares were sold by existing stockholders and certain of our executive officers. The selling 
stockholders received all of the net proceeds of $78.8 million from the secondary public offering. We did not sell 
any shares and did not receive any of the proceeds from the offering and the costs paid by us in connection with the 
offering of $0.8 million were recorded in general and administrative costs in the accompanying consolidated income 
statement.

(d) 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. 

To determine the proper revenue recognition method for each long-term contract, we evaluate whether the 
original contract should be accounted for as one or more performance obligations. This evaluation requires judgment 
and the decisions reached could change the amount of revenue and gross profit recorded in a given period. As most 
of our contracts contain multiple performance obligations, we allocate the total transaction price to each 
performance obligation based on the estimated relative standalone selling prices of the promised goods or services 
underlying each performance obligation. 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; therefore, we 
allocate the total transaction price under our contracts with multiple performance obligations using the contractually 
stated prices, as these prices represent the relative standalone selling price based on an expected cost plus margin 
model.  

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.  In addition, the customer does not have 
return or refund rights for items produced that conform to the specifications included in the contract. Because 
control transfers over time, revenue is recognized based on the extent of progress towards the completion of the 
performance obligation. We use the cost-to-cost input measure of progress for our contracts as this method provides 
the best representation of the production progress towards satisfaction of the performance obligation as the materials 
are distinct to the product being manufactured because of customer specifications provided for in the contract, the 

F-9

TPI COMPOSITES, INC. AND SUBSIDIARIES 

Notes to Consolidated Financial Statements

costs incurred are proportional to the progress towards completion of the product, and the products do not involve 
significant pre-fabricated component parts. 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 contract 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 
significant judgments and estimates relating to the total consideration to be received and the expected total costs to 
complete the performance obligation.  The judgments and estimates relating to the total consideration to be received 
include the amount of variable consideration as our contracts typically provide the customer with a range of 
production output options from guaranteed minimum volume obligations to the production capacity of the facility, 
and customers will provide periodic non-cancellable commitments for the number of wind blades to be produced 
over the term of the agreement.  We use historical experience, customer commitments and forecasted future 
production based on the capacity of the plant to estimate the total revenue to be received to complete the 
performance obligation.  In addition, the amount of revenue per unit produced may vary based on the costs of 
production of the wind blades as we may be able to change the price per unit based on changes in the cost of 
production.  Further, some of our contracts provide opportunities for us to share in labor and material cost savings as 
well as absorb some additional costs as an incentive for more efficient production, both of which impact the margin 
realized on the contract and ultimately the total amount of revenue to be recognized.  Additionally, certain of our 
customer contracts provide for concessions by us for missed production deadlines.  

We estimate variable consideration at the most likely amount to which we expect to be entitled. We include 

estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative 
revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. 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.

Our contracts may be modified to account for changes in specifications of products and changing 

requirements. If the contract modifications are for goods or services that are not distinct from the existing contract, 
they are accounted for as if they were part of the original contract. The effect of a contract modification on the 
transaction price and the measure of progress for the performance obligation to which it relates is recognized as an 
adjustment to revenue on a cumulative catch-up basis. If contract modifications are for goods and services that are 
distinct from the existing contract and increases the amount of consideration reflecting the standalone sale price of 
the additional goods or services, then the contract modification is accounted for as a separate contract and is 
evaluated for one or more performance obligations.  

Each reporting period, we evaluate the progress towards satisfaction of each performance obligation based on 
any contract modifications that have occurred, cost incurred to date, and an estimate of the expected future revenue 
and costs to be incurred to complete the performance obligation. Based on this analysis, any changes in estimates of 
revenue, cost of sales, contract assets and liabilities and the related impact to operating income are recognized on a 
cumulative catch-up basis, which recognizes in the current period the cumulative effect of the changes on current 
and prior periods based on the percentage of completion of the performance obligation.

Wind blade pricing is based on annual commitments of volume as established in our customer contracts and 

orders less than committed volume may result in a higher price per wind blade to our customers. Orders in excess of 
annual commitments may result in discounts to our customers from the contracted price for the committed volume. 
Our customers typically provide periodic purchase orders with the price per wind blade given the current cost of the 
bill of materials, labor requirements and volume desired.  We record an allowance for expected utilization of early 
payment discounts which are reported as a reduction of the related revenue. 

Precision molding and assembly systems included in a customer’s contract are based upon the specific 

engineering requirements and design determined by the customer and are specific to the wind blade design and 
function desired. From the customer’s engineering specifications, a job cost estimate is developed along with a 
production plan, and the desired margin is applied based on the location the work is to be performed and complexity 
of the customer’s design. Precision molding and assembly systems are generally built to produce wind blades which 
may be manufactured by us in production runs specified in the customer contract.

F-10

TPI COMPOSITES, INC. AND SUBSIDIARIES 

Notes to Consolidated Financial Statements

Contract assets 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 and invoices are due based on each customers negotiated payment terms, 
which range from 15 to 90 days.  We apply the practical expedient that allows us to exclude payment terms under 
one year from the transfer of a promised good or service from consideration of a significant financing component in 
its contracts. With regards to the production of precision molding and assembly systems, our contracts generally call 
for progress payments to be made in advance of production. Generally, payment is made at certain percentage of 
completion milestones with the final payment due upon delivery to the manufacturing facility. These progress 
payments are recorded within contract liabilities as current liabilities in the consolidated balance sheets and are 
reduced as we record revenue over time. We evaluate indications that a customer may not be able to meet the 
obligations under our long-term supply agreements to determine if an account receivable or contract asset may be 
impaired.

Our customers may request, in situations where they do not have space available to receive products or do not 
want to take possession of products immediately for other reasons, that their finished products be stored by us in one 
of our facilities. Most of our contracts provide for a limited number of wind blades to be stored during the period of 
the contract with any additional wind blades stored subject to additional storage fees, which are included in the wind 
blade performance obligation revenue.  

Revenue related to non-recurring engineering and freight services provided under our customer contracts is 
recognized at a point in time following the transfer of control of the promised services to the customer. Customers 
usually pay the carrier directly for the cost of shipping associated with items produced.  When we pay the shipping 
costs, we apply the practical expedient that allows us to account for shipping and handling as a fulfillment costs and 
include the revenue in the associated performance obligation and the costs are included in cost of goods sold.

Taxes assessed by a governmental authority that are both imposed on and concurrent with specific revenue-

producing transactions, that are collected by us from a customer, are excluded from revenue.

(e) 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 manufacture of our products and services.

Startup costs represent the unallocated overhead related to both new manufacturing facilities as well as new 

lines in existing manufacturing facilities. Transition costs represent the unallocated overhead related to the transition 
of wind blade models. The startup and transition costs are primarily fixed overhead costs incurred during the period 
production facilities are under-utilized while transitioning wind blade models and ramping up manufacturing, which 
are not allocated to products and are expensed as incurred. 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, manufacturing overhead as a percentage of net sales is 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.

Notes to Consolidated Financial Statements

(f) General and Administrative Expense

General and administrative expenses are primarily 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. In addition, realized gains and losses on the sale of certain receivables, on 
a non-recourse basis under supply chain financing arrangements with our customers, to financial institutions and on 
the sale of other assets at our manufacturing facilities are also included in general and administrative expenses. 

The research and development expenses incurred at our Warren, Rhode Island and Fall River, Massachusetts 

locations as well as at our Kolding, Denmark advanced engineering center are included in general and administrative 
expenses. For the years ended December 31, 2018, 2017 and 2016, total research and development expenses totaled 
$0.8 million, $1.6 million and $1.5 million, respectively. 

For the year ended December 31, 2018, the realized loss on the sale of certain receivables, on a non-recourse 

basis under supply chain financing arrangements with our customers, to financial institutions and the realized loss on 
the sale of other assets at our manufacturing facilities totaled $4.6 million. There were no such amounts for the years 
ended December 31, 2017 and 2016. 

(g) Cash and Cash Equivalents and Restricted Cash

Cash and cash equivalents include highly liquid investments that are readily convertible to known amounts of 
cash with original maturities of three months or less. The carrying value of cash and cash equivalents approximates 
fair value.

As of December 31, 2018 and 2017, our China locations collectively had unrestricted cash totaling $28.9 

million and $46.3 million, respectively, in bank accounts in China. The Chinese government imposes certain 
restrictions on transferring cash out of China. The local governments in Turkey and Mexico impose no such 
restrictions on transferring cash out of the respective country. 

As of December 31, 2018 and 2017, we had provided for cash deposits for letters of guarantee used for 
customs clearance related to our China locations totaling $3.5 million and $3.8 million, respectively.  These amounts 
are reported as restricted cash in our consolidated balance sheets. 

As of December 31, 2018 and 2017, we maintained a long-term deposit in interest bearing accounts, related to 

fully cash-collateralized letters of credit in connection an equipment lessor in Iowa, totaling $0.5 million. See 
Note 9, Other Noncurrent Assets.  

(h) Accounts Receivable

Trade accounts receivable are recorded at the invoiced amount and generally do not bear interest. We follow 

the allowance method of recognizing uncollectible accounts receivable, which recognizes bad debt expense based on 
a review of the individual accounts outstanding and prior history of uncollectible accounts receivable. Credit is 
extended based on evaluation of each of our customer’s financial condition and is generally unsecured. Accounts 
receivable are generally due within 30 days and are stated net of an allowance for doubtful accounts in the 
consolidated balance sheets. Accounts are considered past due if outstanding longer than contractual payment terms. 
We record an allowance based on consideration of a number of factors, including the length of time trade accounts 
are past due, previous loss history, the credit-worthiness of individual customers, economic conditions affecting 
specific customer industries, and economic conditions in general. We charge-off accounts receivable after all 
reasonable collection efforts have been exhausted. We credit payments subsequently received on such receivables to 
bad debt expense in the period payment is received. We record delinquent finance charges on outstanding accounts 
receivables only if they are collected. We wrote off $0.2 million during 2018, $0.2 million during 2017 and $0.5 
million during 2016, and do not have any off-balance-sheet credit exposure related to our customers. See Note 5, 
Accounts Receivable.

Notes to Consolidated Financial Statements

(i) Inventories

Inventories represent materials purchased that are not restricted to fulfillment of a specific contract and are
measured at the lower of cost or net realizable value. Net realizable value is defined as the estimated selling prices in 
the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Cost is
determined using the first-in, first-out method for such raw materials. Write-downs to reduce the carrying cost of 
obsolete, slow-moving, and unusable inventory to net realizable value are recognized in cost of goods sold. The 
effect of these write-downs establishes a new cost basis in the related inventory, which is not subsequently written
up. 

(j) Property, Plant and Equipment

Property, plant and equipment are stated at cost. Depreciation and amortization of property, plant, and 
equipment is calculated on the straight-line method over the estimated useful lives of the assets. See Note 7,
Property, Plant and Equipment, Net.

(k) Recoverability of Long-Lived Assets

We review property, plant and equipment and other long-lived assets in order to assess recoverability based on 
expected future undiscounted cash flows whenever events or circumstances indicate that the carrying value may not 
be recoverable. If the sum of the expected future net cash flows is less than the carrying value, an impairment loss is 
recognized. The impairment loss is measured as the amount by which the carrying value exceeds the fair value of 
the asset.

(l) Goodwill, Intangible Assets and Deferred Costs

Goodwill represents the excess of the acquisition cost of Composite Solutions, Inc. from True North Partners, 
LLC in 2004 over the fair value of identifiable assets acquired and liabilities assumed. Goodwill, which is entirely in 
the U.S. segment, is evaluated for impairment annually on October 31 and whenever events or circumstances make 
it likely that impairment may have occurred. In determining whether impairment has occurred, we use a two-step
approach. Step one compares the fair value of the related reporting unit (calculated using the discounted cash flow 
method) to its carrying value. If the carrying value exceeds the fair value, there is a potential impairment and step
two must be performed. Step two compares the carrying value of the reporting unit’s goodwill to its implied fair 
value (i.e., fair value of reporting unit less the fair value of the unit’s assets and liabilities, including identifiable 
intangible assets). If the implied fair value of goodwill is less than the carrying amount of goodwill, impairment is 
recognized for that difference. We may first assess qualitative factors to determine whether it is necessary to 
perform the two-step quantitative goodwill impairment test. We performed our annual goodwill impairment test 
during 2018 and determined that it is more-likely-than-not that its fair value exceeds its carrying amount.

Our only intangible assets were acquired in a business acquisition and provide contractual or legal rights, or 

other future benefits that could be separately identified. Our valuation of identified intangible assets was based upon
discounted cash flow estimates that require significant management judgment with respect to revenue and expense
growth rates, changes in working capital, and the selection and use of the appropriate discount rate. The intangible 
assets are amortized over their estimated useful life. Intangible assets with indefinite lives are evaluated at least 
annually for impairment or whenever events or circumstances make it likely that impairment may have occurred. 

F-13

TPI COMPOSITES, INC. AND SUBSIDIARIES 

Notes to Consolidated Financial Statements

As a result of our adoption of Topic 606, we recognized an asset for deferred costs incurred to fulfill a contract 

when such costs meet certain criteria.  These deferred costs are amortized over their estimated useful life. See Note 
2, Revenue From Contracts with Customers for a further discussion of those deferred costs recognized as a result of 
the adoption of Topic 606. See Note 8, Intangible Assets and Deferred Costs, Net.

(m) Warranty Expense

We provide a limited warranty for our mold and wind blade products, including materials and workmanship, 

with terms and conditions that vary depending on the product sold, generally for periods that range from two to 
five years. We also provide a limited warranty for our transportation products, including materials and 
workmanship, with terms and conditions that vary depending on the product sold, generally for a period of 
approximately two years. Warranty expense is recorded based upon estimates 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 generally 
reversed against the current year warranty expense amount. See Note 10, Accrued Warranty. 

(n) Treasury Stock

Common stock purchased for treasury is recorded at historical cost. Transactions in treasury shares relate to 

share-based compensation plans and are recorded at weighted-average cost. 

(o) Foreign Currency Translation Adjustments

Our reporting currency is the U.S. dollar. However, we have non-U.S. operating segments in our U.S., 

Mexico, Turkey and China operations

•

•

•

•

•

The U.S. parent companies of our China and Mexico operations, which are wholly-owned subsidiaries 
of TPI Composites, Inc., maintain their books and records in U.S. dollars.

Our Kolding, Denmark operation, which is a wholly-owned subsidiary of TPI Composites, Inc., 
maintains its books and records denominated in the local Danish currency, the Krone. 

Our Mexico operations maintain their books and records through multiple legal entities that are 
denominated in the local Mexican currency, the Peso.

Our Turkey operations maintain their books and records in the local Turkish currency, the Lira.

Our China operations maintain their books and records in the local Chinese currency, the Renminbi.

Foreign currency-denominated assets and liabilities are translated into U.S. dollars at exchange rates existing 
at the respective balance sheet dates. Results of operations of our foreign subsidiaries are translated at the average 
exchange rates during the respective periods. Foreign currency transaction gains and losses are reported in realized 
loss on foreign currency remeasurement in our consolidated income statements. Translation adjustments are reported 
in accumulated other comprehensive loss in our consolidated balance sheets. Currency translation adjustments for 
the years ended December 31, 2018, 2017 and 2016 amounted to a loss of $14.4 million, a gain of $3.3 million and a 
loss of $3.8 million, respectively.

(p) Share-Based Compensation

We maintain two active incentive compensation plans: the 2008 Stock Option and Grant Plan and the 
Amended and Restated 2015 Stock Option and Incentive Plan (the 2015 Plan). In May 2015, our board of directors 
and stockholders adopted and approved the 2015 Plan, which provides for the issuance of incentive stock options, 
non-qualified stock options, stock appreciation rights, restricted stock units, restricted stock awards, unrestricted 
stock awards, cash-based awards, performance share awards and dividend equivalent rights to certain of our 
employees, non-employee directors and consultants. The term of stock options issued under the 2015 Plan may not 
exceed ten years from the date of grant. Under the 2015 Plan, incentive stock options and non-qualified stock 
options are granted at an exercise price that is not to be less than 100% of the fair market value of our common stock 
on the date of grant, as determined by the Compensation Committee of our board of directors. Stock options become 
vested and exercisable at such times and under such conditions as determined by the Compensation Committee on 
the date of grant. Upon approval of the 2015 Plan, no future grants will be made from the 2008 Stock Option and 
Grant Plan.

F-14

TPI COMPOSITES, INC. AND SUBSIDIARIES 

Notes to Consolidated Financial Statements

We use the Black Scholes valuation model, unless the awards are subject to market conditions, in which case 
we utilize a binomial-lattice model (i.e., Monte Carlo simulation model), to determine the fair value of stock options 
and certain performance-based restricted stock units (PSUs) granted pursuant to the 2015 Plan. The Monte Carlo 
simulation model utilizes multiple input variables to determine the share-based compensation expense. For grants 
with market conditions made in the year ended December 31, 2018, we utilized a volatility of 31.1%, a 0% dividend 
yield and a risk-free interest rate of 2.4%. The volatility was based on the most recent comparable period for the 
Company and the peer group. The stock price projection for the Company and the components of the peer group 
assumes a 0% dividend yield. This is mathematically equivalent to reinvesting dividends in the issuing entity over 
the performance period. The risk-free interest rate is equal to the yield, as of the measurement date, of the zero-
coupon U.S. Treasury bill that is commensurate with the remaining performance measurement period.  

The determination of the grant date fair value using an option-pricing model and simulation model requires 
judgment as well as assumptions regarding a number of other complex and subjective variables. These variables 
include our closing market price at the grant date as well as the following assumptions:

Expected Volatility. As our common stock had not been publicly traded prior to July 2016, the expected 
volatility assumption reflects an average of volatilities of publicly traded peer group companies with a period equal 
to the expected life of the options. 

Expected Life (years). We use the simplified method to estimate the expected term of stock options. The 
simplified method for estimating expected term is to use the mid-point between the vesting term and the contractual 
term of the option. We elected to use the simplified method because we did not have historical exercise data to 
estimate the expected term due to the limited time period our common stock had been publicly traded. 

Risk-Free Interest Rate. The risk-free interest rate assumption is based upon the U.S. constant maturity 
treasury rates as the risk-free rate interpolated between the years commensurate with the expected life of the options. 

Dividend Yield. The dividend yield assumption is zero since we do not expect to declare or pay dividends in 

the foreseeable future. 

Forfeitures. Share-based compensation expense is reversed when the service-based award is forfeited.

Expected Vesting Period. We amortize the share-based compensation expense over the requisite service 

period. 

Share-based compensation expense related to restricted stock units and PSUs are expensed over the vesting 
period using the straight-line method for our employees and our board of directors. The restricted stock units and 
PSUs do not have voting rights. We calculate the fair value of our share-based awards on the date of grant for our 
employees and directors. We calculate the fair value of our share-based awards to our consultants on the date of 
vesting. 

(q) Leases

Leases are classified as either operating leases or capital leases. Assets acquired under capital leases are 

amortized on the same basis as similar property, plant and equipment. Rental payments, including rent holidays, 
leasehold incentives, and scheduled rent increases are expensed on a straight-line basis over the lease term including 
any applicable renewals. Leasehold improvements are amortized over the shorter of the depreciable lives of the 
corresponding fixed assets or the lease term including any applicable renewals.

(r) Financial Instruments

Interest Rate Swap

We use interest rate swap contracts to mitigate our exposure to interest rate fluctuations associated with our 

new credit agreement (the Credit Agreement) that we entered into in April 2018. We do not use such swap contracts 
for speculative or trading purposes.

F-15

TPI COMPOSITES, INC. AND SUBSIDIARIES 

Notes to Consolidated Financial Statements

To offset the variability of future interest payments on the Credit Agreement arising from changes in the 
London Interbank Offered Rate (LIBOR), in April 2018, we entered into an interest rate swap agreement with a 
financial institution for a notional amount of $75.0 million with an expiration date of April 2023. This interest rate 
swap effectively hedges $75.0 million of the future variable rate LIBOR interest expense to a fixed rate interest 
expense. The derivative instrument qualified for accounting as a cash flow hedge in accordance with Financial 
Accounting Standards Board (FASB) Accounting Standard Codification (ASC) Topic 815, Derivatives and 
Hedging, and we designated it as such. 

The settlement value of the interest rate swap is $0.8 million as of December 31, 2018 and is included in other 

noncurrent assets in the consolidated balance sheet. The unrealized gain on the swap of $0.6 million, net of tax, is 
included in the consolidated statement of other comprehensive income (loss).  

Forward Contract

We use forward contracts to mitigate our exposure associated with fluctuations in foreign currency exchange 

rates. We do not use such forward contracts for speculative or trading purposes. 

In August 2018, we provided a Turkish Lira denominated intercompany loan to an EMEAI subsidiary of 

$15.0 million converted at the spot rate on the transaction date to 96.6 million Turkish Lira to fund their working 
capital requirements. We entered into a forward contract, with the same expiration as that of the intercompany loan’s 
maturity in October 2018, for a notional amount of 101.5 million Turkish Lira to reduce our exposure to currency 
fluctuations from the settlement of this Turkish Lira denominated intercompany loan. The derivative instrument 
qualifies for accounting as a cash flow hedge in accordance with FASB ASC Topic 815, Derivatives and Hedging, 
and we designated it as such at inception. The forward contract was settled in October 2018.  

(s) Income Taxes

Income taxes are accounted for under the asset and liability method in accordance with FASB ASC Topic 740, 

Income Taxes. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable 
income in the years in which those differences are projected to be recovered or settled. Realization of deferred tax 
assets is dependent on our ability to generate sufficient taxable income of an appropriate character in future periods. 
A valuation allowance is established if it is determined to be more-likely-than-not that a deferred tax asset will not 
be realized. Interest and penalties related to unrecognized tax benefits are reported in income tax expense, See 
Note 15, Income Taxes.

(t) Net Income Attributable to Preferred Stockholders

Net income attributable to preferred stockholders relates to the accrual of dividends on our convertible and 
senior redeemable preferred shares, the accretion to redemption amounts on our convertible preferred shares and 
warrant fair value adjustment. Immediately prior to the closing of our IPO, all preferred shares were converted into 
shares of our common stock and as a result, the accrual of dividends ceased.

Notes to Consolidated Financial Statements

(u) Net Income Per Share Calculation

The basic net income per common share is computed by dividing the net income by the weighted-average 

number of common shares outstanding during a period. Diluted net income per common share is computed by 
dividing the net income by the weighted-average number of common shares outstanding plus potentially dilutive 
securities using the treasury stock method. The table below reflects the calculation of the weighted-average number 
of common shares outstanding, using the treasury stock method, used in computing basic and diluted earnings per 
common share for the years ended December 31:  

Basic weighted-average shares outstanding

Share-based compensation awards of 30,000 shares were excluded from the computation of diluted net income 

per share for the year ended December 31, 2018 because their effect would be anti-dilutive.  We did not have any
potential dilutive securities which were excluded from the computation of diluted net income per share for the years
ended December 31, 2017 and 2016.

(v) Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting 

principles (GAAP) requires management to make estimates and assumptions that affect the reported amounts of 
assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial 
statements and the reported amounts of revenues and expenses during the reporting period. Actual results could 
differ from those estimates. Significant items subject to such estimates and assumptions include the useful lives of 
property, plant and equipment, realizability of intangible assets, deferred costs and deferred tax assets, inventory 
valuation, relative selling prices and cost assumptions for revenue recognition, fair value of stock options, 
performance-based restricted stock units and warrants, warranty reserves and other contingencies.

(w) Fair Value of Financial Instruments

FASB ASC Topic 820, Fair Value Measurements, defines fair value as the price that would be received to sell 
an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. 
Topic 820 also specifies a fair value hierarchy that requires an entity to maximize the use of observable inputs and 
minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs 
that may be used to measure fair value is follows:

Level 1: Quoted prices in active markets for identical assets or liabilities;

Level 2: Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities;
quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by 
observable market data for substantially the full term of the assets or liabilities; and

Level 3: Valuation is generated from model-based techniques that use significant assumptions not observable
in the market. These unobservable assumptions reflect our own estimate of assumptions that market 
participants would use in pricing the asset or liability.

The carrying amounts of cash and cash equivalents, trade accounts receivable, income taxes receivable,
accounts payable and accrued expenses and income taxes payable approximate fair value because of the short-term 
nature of these financial instruments. The carrying amount of working capital loans approximates fair value due to
their short term nature and the loans carry a current market rate of interest, a level 2 input. The carrying value of 
long-term debt approximates fair value based on its variable rate index or based upon market interest rates available 
to us for debt of similar risk and maturities, both of which are level 2 inputs.

(x) Recently Issued Accounting Pronouncements

Accounting Pronouncements Adopted in 2018 

Revenue from Contracts with Customers

In May 2014, the FASB issued Topic 606, which provides new recognition and disclosure requirements for 

revenue from contracts with customers that supersedes the existing revenue recognition guidance. The new 
recognition requirements focus on when the customer obtains control of the goods or services, rather than the 
current risks and rewards model of recognition. The core principle of the new standard is that an entity will 
recognize revenue when it transfers goods or services to its customers in an amount that reflects the consideration an 
entity expects to be entitled to for those goods or services. The new disclosure requirements included in these
financial statements contain information intended to communicate the nature, amount, timing and any uncertainty of 
revenue and cash flows from the applicable contracts, including any significant judgments and changes in judgments
and assets recognized from the costs to obtain or fulfill a contract. 

We adopted Topic 606 as of January 1, 2018 with retrospective application to January 1, 2016 through 
December 31, 2017.  See Note 2, Revenue From Contracts with Customers and Note 19, Adjustments to Previously
Reported Financial Statements from the Adoption of an Accounting Pronouncement, for further discussion of the
adoption of this standard, including the impact on our previously reported financial statements. 

Cash Flow Presentation

In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments, 

that clarifies how certain cash receipts and cash payments are presented and classified in the  consolidated 
statements of cash flows.  In addition, in November 2016, the FASB issued ASU 2016-18, Restricted Cash, that 
requires restricted cash and cash equivalents to be included with the amount of cash and cash equivalents that are
reconciled on the consolidated statements of cash flows. We adopted these ASUs as of January 1, 2018 with
retrospective application to each period presented. 

The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the 

consolidated balance sheets which total the same such amounts in the consolidated statements of cash flows:

reported financial statements.

Income Taxes   

In December 2017, the Securities and Exchange Commission (SEC) staff issued Staff Accounting Bulletin 

118 (SAB 118), which provides relief for companies that have not completed their accounting for the effects of The
Tax Cuts and Jobs Act (Tax Reform Act) but can determine a reasonable estimate of those effects to allow them to 
include a provisional amount based on their reasonable estimate in their financial statements. The guidance in SAB
118 also allows companies to adjust the provisional amounts during a one-year “measurement period” which is
similar to the measurement period used when accounting for business combinations. In the accompanying
consolidated financial statements, we have completed our accounting for all the tax effects associated with the 
enactment of the Tax Reform Act. See Note 15, Income Taxes, for further discussion.

Notes to Consolidated Financial Statements

Share-Based Compensation

In May 2017, the FASB issued ASU 2017-09, Scope of Modification Accounting, which provides guidance 

about which changes to terms or conditions of share-based payment awards requires an entity to apply the 
modification accounting of Topic 718, Compensation-Stock Compensation.  This standard is effective for all entities 
for annual and interim periods beginning after December 15, 2017, with early adoption permitted. We adopted this 
standard on January 1, 2018 and it did not have a material effect on our consolidated financial statements.

Financial Instruments

In August 2017, the FASB issued ASU 2017-12, Targeted Improvements to Accounting for Hedging 
Activities, which simplifies the application of hedge accounting guidance, including eliminating the requirement to 
separately measure and report hedge ineffectiveness. This standard is effective for all public business entities for 
annual and interim periods beginning after December 15, 2018, with early adoption permitted. We adopted this 
standard on January 1, 2018 and it did not have a material effect on our consolidated financial statements.

Accounting Pronouncements Not Yet Adopted

Leases

In February 2016, the FASB established Topic 842, Leases, by ASU No. 2016-02, which requires lessees to 

recognize leases on-balance sheet and disclose key information about leasing arrangements. Topic 842 was 
subsequently amended by ASU No. 2018-01, Land Easement Practical Expedient for Transition to Topic 842; ASU 
No. 2018-10, Codification Improvements to Topic 842, Leases; and ASU No. 2018-11, Targeted Improvements. The 
new standard establishes a right-of-use model (ROU) that requires a lessee to recognize a ROU asset and lease 
liability on the balance sheet for all leases with a term longer than 12 months. Leases will be classified as finance or 
operating, with classification affecting the pattern and classification of expense recognition in the income statement.

This standard is effective for all public business entities for annual and interim periods beginning after 
December 15, 2018, with early adoption permitted. A modified retrospective transition approach is required, 
applying the new standard to all leases existing at the date of initial application. An entity may choose to use either 
(1) its effective date or (2) the beginning of the earliest comparative period presented in the financial statements as 
its date of initial application. We will adopt this new standard on January 1, 2019 and use the effective date as our 
date of initial application. Consequently, financial information will not be updated and the disclosures required 
under the new standard will not be provided for dates and periods before January 1, 2019. 

The new standard provides a number of optional practical expedients in transition. We expect to elect the 
package of practical expedients, which permits us not to reassess under the new standard our prior conclusions about 
lease identification, lease classification and initial direct costs. We do not expect to elect the use-of-hindsight or the 
practical expedient pertaining to land easements, the latter not being applicable to us.

We expect that this standard will have a material effect on our financial statements. While we continue to 
assess all of the effects of adoption, we currently believe the most significant effects relate to the recognition of new 
ROU assets and lease liabilities on our balance sheet for our real estate, equipment and auto operating leases and 
providing significant new disclosures about our leasing activities. 

On adoption, we currently expect to recognize additional operating liabilities of approximately $135 million, 

with corresponding ROU assets of approximately the same amount based on the present value of the remaining 
minimum rental payments under current leasing standards for existing operating leases.

The new standard also provides practical expedients for an entity’s ongoing accounting. We currently expect 

to elect the short-term lease recognition exemption for all leases that qualify. Accordingly, for those leases that 
qualify, we will not recognize ROU assets or lease liabilities, and this includes not recognizing ROU assets or lease 
liabilities for existing short-term leases of those assets in transition. We also currently expect to elect the practical 
expedient to not separate lease and non-lease components for all of our leases.

Income Taxes

In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated 

Other Comprehensive Income, which allows a reclassification from accumulated other comprehensive income to 
retained earnings stranded tax effects resulting from the Tax Reform Act. This standard is effective for all entities 
for annual and interim periods beginning after December 15, 2018, with early adoption permitted. We will adopt this
standard on January 1, 2019 and do not expect that it will have a material impact on our consolidated financial 
statements.

Share-Based Compensation

In June 2018, the FASB issued ASU 2018-07, Improvements to Nonemployee Share-Based Payment 
Accounting, which expands the scope of Topic 718, Compensation-Stock Compensation, to include share-based 
payment transactions for acquiring goods and services from nonemployees.  This standard is effective for all public 
business entities for annual and interim periods beginning after December 15, 2018. Early adoption is permitted, but 
no earlier than our adoption date of Topic 606. We will adopt this standard on January 1, 2019 and do not expect 
that it will have a material impact on our consolidated financial statements.

In July 2018, the FASB issued ASU 2018-09, Codification Improvements, which contains amendments that 
affect a wide variety of Topics in the Codification, including amendment to Subtopic 718-40, Compensation-Stock 
Compensation-Income Taxes, that clarifies the timing of when an entity should recognize excess tax benefits. This 
standard is effective for all public business entities for annual periods beginning after December 15, 2018. We will 
adopt this standard on January 1, 2019 and are currently evaluating the impact of the adoption of this standard on 
our consolidated financial statements.

There have been no other recent accounting pronouncements or changes in accounting pronouncements during

In addition, most of our net sales are made directly to our customers, primarily large multi-national wind 

turbine manufacturers, under our long-term contracts which are typically five years in length.

Contract Assets and Liabilities

Contract assets consist of the amount of revenue recognized over time for performance obligations in 
production where control has transferred to the customer but the contract does not yet allow for the customer to be 
billed.  Typically, customers are billed when the product finishes production and meets the technical specifications 
contained in the contract. The contract assets are recorded as current assets in the consolidated balance sheets.
Contract liabilities consist of advance payments in excess of revenue earned. These amounts were historically
recorded as customer deposits which usually relate to progress payments received as precision molding and 
assembly systems were being manufactured. The contract liabilities are recorded as current liabilities in the 
consolidated balance sheets and are reduced as we record revenue over time.  

These contract assets and liabilities are reported on the consolidated balance sheets net on a contract-by-

contract basis at the end of each reporting period, as demonstrated in the table below.

Contract assets and contract liabilities consisted of the following:

Contracts assets increased by $11.1 million from December 31, 2017 to December 31, 2018 due to 

incremental unbilled production during the year ended December 31, 2018. Contracts liabilities increased by $4.4 
million from December 31, 2017 to December 31, 2018 due to the amounts billed to customers exceeding the 
revenue earned related to precision molding and assembly systems and wind blades being produced in the year 
ended December 31, 2018.

The time it takes to produce a single blade is typically between 5 to 7 days. The time it takes to produce a

mold is typically between 3 to 6 months.

TPI COMPOSITES, INC. AND SUBSIDIARIES 

Notes to Consolidated Financial Statements

For the year ended December 31, 2018, we recognized $2.8 million of revenue that was included in the 

corresponding contract liability balance at the beginning of the period.

Performance Obligations

Remaining performance obligations represent the transaction price of firm orders for which work has not been 

performed and excludes any unexercised contract options. 

For the year ended December 31, 2018, net revenue recognized from our performance obligations satisfied in 

previous periods decreased by $12.7 million. This primarily relates to changes in certain of our estimated total 
contract values and related percentage of completion estimates. 

As of December 31, 2018, the aggregate amount of the transaction price allocated to the remaining 

performance obligations to be satisfied in future periods was approximately $5.6 billion. We estimate that we will 
recognize the remaining performance obligations as revenue as follows: 27 percent in 2019, 28 percent in 2020, 20 
percent in 2021, 15 percent in 2022 and the remaining 10 percent in 2023.

Pre-Production Investments

We recognize an asset for deferred costs incurred to fulfill a contract when those costs meet all of the 
following criteria:  (a) the costs relate directly to a contract or to an anticipated contract that we can specifically 
identify; (b) the costs generate or enhance our resources that will be used in satisfying performance obligations in 
the future; and, (c) the costs are expected to be recovered. We capitalize the costs related to training our workforce 
to execute the manufacturing services and other facility set-up costs related to preparing for production of a specific 
contract.  We factor these costs into our estimated cost analysis for the overall contract.  Costs capitalized are 
amortized over the number of units produced during the contract term. As of December 31, 2018, the cost and 
accumulated amortization of such assets totaled $5.6 million and $2.1 million, respectively. As of December 31, 
2017, the cost and accumulated amortization of such assets totaled $2.4 million and $1.4 million, respectively. These 
amounts are included in intangible assets and deferred costs, net in the consolidated balance sheet. See Note 8, 
Intangible Assets and Deferred Costs, Net.

In applying the practical expedient as permitted under Topic 606, we recognize the incremental costs of 
obtaining contracts as an expense when incurred if the amortization period of the asset that we otherwise would have 
recognized is one year or less.  These costs are included in cost of goods sold.

Note 3. Significant Risks and Uncertainties

Our revenues and receivables are from a small number of customers. As such, our production levels are 

dependent on these customers’ orders. See Note 16, Concentration of Customers. 

We maintain our U.S. cash in bank deposit accounts that, at times, exceed U.S. federally insured limits. U.S. 

bank accounts are guaranteed by the Federal Deposit Insurance Corporation (FDIC) in an amount up to $250,000 
during 2018 and 2017. At December 31, 2018 and 2017, we had $53.7 million and $98.9 million, respectively, of 
cash in deposit accounts in high quality U.S. banks, which was in excess of FDIC limits. We have not experienced 
losses in any such accounts.

We also maintain cash in bank deposit accounts outside the U.S. with no insurance. At December 31, 2018, 
this includes $1.0 million in Turkey, $28.9 million in China and $1.7 million in Mexico. We have not experienced 
losses in these accounts. In addition, we have short-term deposits in interest bearing accounts of $3.5 million in 
China, which are reported as restricted cash in our consolidated balance sheets. We also have long-term deposits in 
interest bearing accounts of $0.5 million in Iowa. See Note 9, Other Noncurrent Assets.

Note 4. Related-Party Transactions

Related party transactions include transactions between us and certain of our affiliates. The following 

transactions were in the normal course of operations and were measured at the exchange amount, which is the 
amount of consideration established and agreed to by the parties.

We have previously entered into several agreements with subsidiaries of General Electric Company and its 

consolidated affiliates (GE) relating to the operation of its business. As a result of these agreements, GE has been a 
debtor, creditor and holder of both our preferred and common shares. During the second quarter of 2017, GE
reduced its holdings of our common shares to less than five percent of the total shares outstanding and then
completely divested of our common shares during the third quarter of 2017.

We have entered into five separate supply agreements with GE to manufacture wind blades in Newton, Iowa; 

Taicang Port, China; Juárez, Mexico (2) and Izmir, Turkey. The supply agreements in Taicang Port, China and 
Izmir, Turkey expired on December 31, 2017. For the six months ended June 30, 2017, we recorded related-party
sales with GE of $198.6 million. As disclosed in Note 16, Concentration of Customers, for the year ended 
December 31, 2016, we recorded related-party sales with GE of $372.3 million.

In January 2016, we entered into an agreement with GE and received an advance of $2.0 million, which we 

repaid in full in August 2016. 

Certain of our existing stockholders, consisting of entities associated with Element Partners, Angeleno Group
and Landmark Partners, each of which is an affiliate of a member of our board of directors, as well as certain of our 
executive officers and a director, purchased an aggregate of 1,250,000 shares of our common stock in the IPO. In
addition, all outstanding obligations and accrued interest under our subordinated convertible promissory notes held 
by certain of our existing stockholders, including Element Partners, Angeleno Group and Landmark Partners, were
converted into an aggregate of 1,079,749 shares of our common stock concurrent with the closing of the IPO at the 
public offering price of $11.00 per share.

In connection with our secondary offering in May 2017, certain entities associated with Element Partners, 
Angeleno Group, Landmark Partners and NGP Energy Technology Partners, L.P, as well as certain of our executive 
officers sold an aggregate of 5,075,000 shares of our common stock at the public offering price of $16.35 per share.

Note 11. Share-Based Compensation

Since 2015, we have granted awards of stock options, restricted stock units (RSUs) and performance-based 
restricted stock units to certain employees and non-employee directors under the 2015 Plan. Each award granted 
prior to the consummation of our IPO included a performance condition that required the completion of an initial
public offering by us and a required vesting period of one to four years commencing upon achievement of the
performance condition. As the IPO was consummated in July 2016, we began recording compensation expense in 
July 2016 for the requisite service period from the grant date through the IPO date with the balance of the share-
based compensation to be expensed over the remaining vesting period.

Upon completion of the IPO and the achievement of the performance condition in 2016, we recorded share-

based compensation expense for the requisite service period from the grant date which included approximately $3.6 
million related to the portion of the service period from the grant date through December 31, 2015.

The share-based compensation expense recognized in the consolidated income statements for the years ended

Notes to Consolidated Financial Statements

As of December 31, 2018, the unamortized cost of the outstanding RSUs and PSUs was $3.4 million and $3.1
million, respectively, which we expect to recognize in the consolidated financial statements over weighted-average 
periods of approximately 1.6 years and 2.2 years, respectively. Additionally, the total unrecognized cost related to 
non-vested stock option awards was $1.6 million, which we expect to recognize in the consolidated financial
statements over a weighted-average period of approximately 1.4 years. 

As of December 31, 2017, the unamortized cost of the outstanding RSUs was $5.0 million, which we expected 

to recognize in the consolidated financial statements over a weighted-average period of approximately 1.5 years. 
Additionally, the total unrecognized cost related to non-vested stock option awards was $4.8 million, which we
expected to recognize in the consolidated financial statements over a weighted-average period of approximately 1.8 
years.

As of December 31, 2016, the unamortized cost of the outstanding RSUs was $2.8 million, which we expected 

to recognize in the consolidated financial statements over a weighted-average period of approximately 1.8 years. 
Additionally, the total unrecognized cost related to non-vested stock option awards was $7.3 million, which we
expected to recognize in the consolidated financial statements over a weighted-average period of approximately 2.1 
years.

The fair value of the stock options granted during the years ended December 31 were calculated using the

Senior Financing Agreements (U.S.):

In December 2017, we amended our previous credit facility (the Credit Facility) to consent to the restructuring 

of our parent and subsidiaries, decreased the variable interest rate to LIBOR, with a 1.0% floor, plus 5.25% and the 
amendment of certain capital expenditure and other financial covenants.  In connection with this amendment, the 
amendment fee of $0.4 million was recorded as a debt issuance cost and was being amortized to interest expense 
over the remaining term of the Credit Facility (36 months) using the effective interest method. As of December 31, 
2017, the aggregate outstanding balance under the Credit Facility was $74.1 million.

In April 2018, we entered into a new credit agreement (the Credit Agreement) with four lenders consisting of 

a multi-currency, revolving credit facility in an aggregate principal amount of $150.0 million, including a $25.0 
million letter of credit sub-facility. On the closing date we drew down $75.4 million on the revolving credit facility 
in connection with the closing of the transactions contemplated by the Credit Agreement and used the proceeds to 
pay all outstanding amounts due and payable under the Credit Facility, various fees and expenses and accrued 
interest. All borrowings and amounts outstanding under the Credit Agreement are scheduled to mature in April 
2023. 

In connection with the Credit Agreement, we expensed $2.0 million of deferred financing costs associated 

with the Credit Facility and a $1.4 million prepayment penalty within the caption “Loss on extinguishment of debt” 
in the accompanying consolidated income statements. In addition, we incurred debt issuance costs related to the 
Credit Agreement totaling $1.0 million which will be amortized to interest expense over the five-year term of the 
Credit Agreement using the effective interest method.

Interest accrues at a variable rate equal to LIBOR plus an initial margin of 1.5% (4.0% as of December 31, 

2018), which may vary based on our total net leverage ratio as defined in the Credit Agreement. Interest is paid 
monthly and we are not obligated to make any principal repayments prior to the maturity date provided we are not in 
default under the Credit Agreement. We may prepay the borrowings under the Credit Agreement without penalty. 

In April 2018, we also entered into an interest rate swap arrangement to fix a notional amount of $75.0 million 

of the Credit Agreement at an effective interest rate of 4.2% for a period of five years.  

As of December 31, 2018, there was $90.4 million outstanding under the Credit Agreement. 

Due to the revolving credit facility’s variable interest rate of LIBOR plus a competitive spread, we estimate 

that fair-value approximates the face value of these notes.

Accounts Receivable, Secured and Unsecured Financing:

EMEAI: During 2014, we renewed a general credit agreement, as amended, with a financial institution in 

Turkey to provide up to 21.0 million Euro of short-term collateralized financing on invoiced accounts receivable of 
one of our customers in Turkey. Interest accrues annually at a fixed rate of 9.1% and is paid quarterly. In December 
2014, and later amended, we obtained an additional $5.0 million of unsecured financing in Turkey under the credit 
agreement, increasing the total facility. All credit agreement terms remained the same. The credit agreement does 
not have a maturity date, however the limits are reviewed in September of each year. As of December 31, 2017, 
there was $6.8 million of accounts receivable financing and no unsecured financing outstanding. During the fourth 
quarter of 2018, we replaced the accounts receivable financing facility with the accounts receivable assignment 
agreement discussed below. As of December 31, 2018, there were no amounts outstanding under the unsecured 
financing facility. 

In 2014, we entered into a credit agreement with a Turkish financial institution to provide up to $16.0 million 
of short-term financing of which $10.0 million is collateralized financing on invoiced accounts receivable of one of 
our customers in Turkey, $5.0 million is unsecured financing and $1.0 million is related to letters of guarantee. 
Interest accrues at a variable rate of the three month Euro Interbank Offered Rate (EURIBOR) plus 6.5%. During 
the first quarter of 2018, the collateralized financing on invoiced accounts receivables and unsecured financing 
facilities were retired and the letters of guarantee limit was decreased to $0.6 million. No amounts were outstanding 
under this agreement as of December 31, 2018 or 2017. 

F-29

TPI COMPOSITES, INC. AND SUBSIDIARIES 

Notes to Consolidated Financial Statements

In 2016, we entered into a general credit agreement, as amended, with a Turkish financial institution to 
provide up to 31.0 million Euro (approximately $35.5 million as of December 31, 2018) of short-term financing of 
which 15.0 million Euro (approximately $17.2 million as of December 31, 2018) is collateralized financing based on 
invoiced accounts receivables of two of our customers in Turkey, 15.0 million Euro (approximately $17.2 million as 
of December 31, 2018) for the collateralized financing of capital expenditures and 1.0 million Euro (approximately 
$1.2 million as of December 31, 2018) related to letters of guarantee. Interest on the collateralized financing based 
on invoiced accounts receivables of two of our customers in Turkey accrues at a fixed rate of 9.0% as of December 
31, 2018 and is paid quarterly with a maturity date equal to four months from the applicable invoice date. Interest on 
the collateralized capital expenditures financing accrues at the one month EURIBOR plus 6.75% (6.75% as of 
December 31, 2018) with monthly principal repayments beginning in October 2017 with a final maturity date of 
December 2021. Interest on the letters of guarantee accrues at 2.00% annually with an amended final maturity date 
of December 2018. As of December 31, 2018 and 2017, there was $12.2 million and $16.9 million outstanding 
under the collateralized financing of capital expenditures line, respectively. Additionally, as of December 31, 2018 
and 2017, there was $14.5 million and $7.3 million, respectively, outstanding under the collateralized financing 
based on invoiced accounts receivables. 

In the fourth quarter of 2018, we entered into a credit agreement with a Turkish financial institution to provide 
up to 100 million Turkish Lira (approximately $18.9 million as of December 31, 2018) of collateralized financing on 
invoiced accounts receivable of one of our customers in Turkey. Interest accrues at a fixed rate of 4.5% and is paid 
quarterly. The credit agreement does not have a maturity date, however the limit will be reviewed in October of each 
year. No amounts were outstanding under this agreement as of December 31, 2018.

Due to the short-term nature of the unsecured financings in the EMEAI segment, we estimate that fair-value 

approximates the face value of the notes.

Asia: In February 2017, we entered into a credit agreement, as amended, with a Chinese financial institution 

to provide an unsecured credit line of up to 210.0 million Renminbi (approximately $30.6 million as of 
December 31, 2018) which can be used for the purpose of domestic and foreign currency loans, issuing customs 
letters of guarantee or other transactions approved by the lender. Interest on the credit line accrues at the Chinese 
central bank interest rate plus an applicable margin (4.8% as of December 31, 2018) and can be paid monthly, 
quarterly or at the time of the debt’s maturity (extended to January 2020). As of December 31, 2018 and 2017, there 
were 92.8 million Renminbi (approximately $13.5 million) and 127.0 million Renminbi (approximately $19.5 
million) of letters of guarantee used for customs clearance outstanding, respectively. 

In March 2018, we entered into a credit agreement with a Chinese financial institution to provide an unsecured 

credit line of up to 100.0 million Renminbi (approximately $14.6 million as of December 31, 2018) of which 70.0 
million Renminbi (approximately $10.2 million as of December 31, 2018) can be used as customs letters of 
guarantee and 30.0 million Renminbi (approximately $4.4 million as of December 31, 2018) can be used for 
working capital. Interest on the credit line accrues at the Chinese central bank interest rate plus an applicable margin 
(4.8% at December 31, 2018) and can be paid monthly, quarterly or at the time of the debt’s maturity (in March 
2023).  As of December 31, 2018, there were no amounts outstanding under this credit agreement. 

Equipment Leases and Other Arrangements: 

U.S.: In 2014, we entered into a lease agreement, as amended, with a leasing company for the lease of up to 

$5.4 million of machinery and equipment at our Iowa facility. The lease included an implied effective interest rate of 
4.3% annually and required monthly payments during each 24 month term. The amounts outstanding under this 
agreement as of December 31, 2018 and 2017, were $0.1 million and $0.5 million, respectively.  

EMEAI: In 2013, we entered into a finance lease agreement with a financial institution in Turkey for the 

initial lease of up to $4.9 million of machinery, equipment and building improvements at our first Turkey facility. 
The term of the lease was for four years at an effective interest rate of 6.0%. The loan was to be repaid in monthly 
installments through 2017. The financing agreement was subsequently amended in 2017 to include our second 
Turkey facility and increase the amount of machinery, equipment and building improvements available for lease to 
$10.0 million. As a result of the amendment, the loan is to be repaid in monthly installments through 2022. All other

financing agreement terms remained the same. The balance outstanding as of December 31, 2018 and 2017 was $6.7 
million and $5.1 million, respectively.

Mexico: In 2016, we entered into a lease agreement, as amended, with a leasing company for the lease of up 
to $10.0 million of machinery and equipment at our second Mexico facility. The lease includes an implied effective 
interest rate of 4.3% annually and requires monthly payments during each 24 month term. The amounts outstanding 
under this agreement as of December 31, 2018 and 2017 were $0.7 million and $5.0 million, respectively. 

In March 2017, we entered into a sale-lease agreement with a leasing company for the initial lease of up to 

$12.0 million of machinery and equipment at our third Mexico facility. The lease includes an implied effective 
interest rate of 4.3% annually and requires monthly payments during each 24 month term. The amounts outstanding 
under this agreement as of December 31, 2018 and 2017 were $3.2 million and $7.4 million, respectively.

In March 2018, we entered into a sale-lease agreement with a leasing company for the initial lease of up to 

$15.0 million of machinery and equipment at our Matamoros, Mexico facility. The lease includes an implied 
effective interest rate of 6.7% annually and requires monthly payments during each 48 month term. The amount 
outstanding under this agreement as of December 31, 2018 was $10.5 million.

Costs associated with the issuance of debt are presented net of the related debt and are amortized over the term 

of the debt using the effective interest rate method. For the years ended December 31, 2018, 2017 and 2016, $0.3 
million, $0.6 million and $1.7 million of debt issuance costs were amortized to interest expense in our consolidated 
income statements, respectively.

The average interest rate on our short-term borrowings as of December 31, 2018 and 2017 was approximately

7.7% and 5.9%, respectively.

(b) Common Stock Warrants

In connection with the note purchase agreement dated December 29, 2014, for the purchase of $10.0 million

of subordinated convertible promissory notes, a minimum of 160,424 warrants were issued to purchase common 
stock with an exercise price equal to the lesser of $24.30 or 85% of the IPO price of $11.00 per share, accordingly,
after the IPO, the exercise price was $9.35. The warrants were immediately exercisable and expired no later than
eight years from the date of issuance. The unamortized fair value of the warrants was expensed upon conversion of 
the convertible promissory notes concurrent with the IPO. These warrants were all exercised during 2018.

(c) Legal Proceedings 

From time to time, we may be involved in disputes or litigation relating to claims arising out of its operations.

In March 2015, a complaint was filed against us in the Superior Court of the State of Arizona (Maricopa 
County) by a former employee, alleging that we had agreed to compensate the employee upon any future sale of the 
Company. We filed a motion to dismiss the complaint in April 2015, which was denied. We subsequently filed an
answer to the complaint in July 2015 denying the substantive allegations of the complaint. The parties completed 
court-ordered mediation in December 2015 but were not able to reach a settlement. We filed a motion for summary
judgment to dismiss the complaint in April 2016 and the court denied the motion in August 2016. The court has set a
trial date for June 2019. We continue to deny the substantive allegations of the complaint and intend to vigorously 
defend this lawsuit; however, we are currently unable to determine the ultimate outcome of this case.

In August 2015, we entered into a transition agreement with our former Senior Vice President – Asia, pursuant 

to which that individual transitioned out of this role at the end of 2015 and was to serve in a consulting capacity in
2016 and 2017. In January 2016, following our discovery that the individual had materially violated the terms of the 
transition agreement, we terminated the consultancy for cause. In April 2016, an arbitration claim was filed in China 
by the individual with the Taicang Labor and Personnel Dispute Arbitration Committee alleging that we improperly 
terminated the transition agreement. The individual is demanding that we honor the terms of the transition 
agreement and pay compensation and fees under the transition agreement, which in the aggregate totals 
approximately $2.6 million. In addition, the individual is also challenging the validity of our termination of an 
option to purchase 164,880 shares of our common stock and 77,760 restricted stock units awarded under the 2015 
Plan, which were canceled in January 2016 when the consultancy was terminated. The Taicang Labor and Personnel 
Dispute Arbitration Committee awarded damages to the individual of approximately $1.2 million but rejected the 
claims regarding the termination of the stock option and restricted stock unit awards. We subsequently appealed the 
arbitration award in favor of the individual to the Taicang Municipal People’s Court, which affirmed the arbitration
award in June 2018. We appealed this judgment to an appellate level court in the Jiangsu Province and the appellate
court affirmed the judgment of the Taicang Municipal People’s court and we paid the judgement award in the fourth
quarter of 2018. We currently are evaluating whether to further appeal this matter. 

In June 2018, Iowa OSHA, a division of the Iowa Department of Labor, issued a citation and notification of 

penalty to us alleging that certain of our workplace practices and conditions at our Newton, Iowa wind blade 
manufacturing facility had violated the Iowa Occupational Safety and Health Act. Specifically, the citation cited us 
for multiple alleged violations and proposed that we pay an aggregate penalty of $0.2 million. In June 2018, we 

F-32

TPI COMPOSITES, INC. AND SUBSIDIARIES 

Notes to Consolidated Financial Statements

notified Iowa OSHA that we were contesting all of the alleged violations and proposed penalties. In June 2018, the 
Labor Commissioner of the Iowa Department of Labor subsequently filed a complaint with the State of Iowa 
Employment Appeal Board, petitioning the appeal board to affirm the citation and notification of penalty that Iowa 
OSHA issued to us. In July 2018, we then filed a response with the appeal board denying the substantive allegations 
of the complaint. A hearing date has been set for June 2019 and the matter remains pending. 

From time to time, we are party to various lawsuits, claims, and other legal proceedings that arise in the 
ordinary course of business, some of which are covered by insurance. Upon resolution of any pending legal matters, 
we may incur charges in excess of presently established reserves. Our management does not believe that any such 
charges would, individually or in the aggregate, have a material adverse effect on our financial condition, results of 
operations or cash flows.

(d) Insurance/Self-Insurance 

We use a combination of insurance and self-insurance for a number of risks, including claims related to our 

employee health care, workers’ compensation and general liability. Liabilities associated with these risks are 
estimated based on, among other things, historical claims experience, severity factors, and other actuarial 
assumptions. Our loss exposure related to self-insurance is limited by stop loss coverage on a per occurrence and 
aggregate basis. We regularly analyze our reserves for incurred but not reported claims, and for reported but not paid 
claims related to our self-funded insurance programs.  While we believe our reserves are adequate, significant 
judgment is involved in assessing these reserves such as assessing historical paid claims, average lags between the 
claims’ incurred date, reported dates and paid dates, and the frequency and severity of claims.  There may be 
differences between actual settlement amounts and recorded reserves and any resulting adjustments are included in 
expense once a probable amount is known. 

(e) Dividend Restrictions

Certain of our subsidiaries are limited in their ability to declare dividends without first meeting statutory 

restrictions of the People’s Republic of China, including retained earnings as determined under Chinese-statutory 
accounting requirements. Until 50% ($21.6 million) of registered capital is contributed to a surplus reserve, our 
Chinese 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, we can pay dividends equal to 100% of after-tax profit 
assuming other conditions are met. At December 31, 2018, the amount of the surplus reserve fund was $6.5 million.

(f) Collective Bargaining Agreements

In 2016, we entered into a three-year collective bargaining agreement with certain of our employees at our 
first Turkey facility. The agreement resulted in an average increase in pay of approximately 20% for employees 
covered by the agreement. In addition, beginning in July 2017, this collective bargaining arrangement also covered 
similarly situated employees at our second Turkey facility. In March 2018, we entered into a collective bargaining 
agreement with a labor union for certain of our employees at the Matamoros, Mexico facility. Currently, there are no 
other employees covered by collective bargaining agreements. We believe that our relations with employees are 
good, and there have been no major work stoppages in recent years.  

Note 14. Defined Contribution Plan

We maintain a 401(k) plan for all of our U.S. employees. Under the 401(k) plan, eligible employees may 
contribute, subject to statutory limitations, a percentage of their salaries. We currently match 50 percent of the 
participants’ contributions up to eight percent of eligible compensation.

F-33

TPI COMPOSITES, INC. AND SUBSIDIARIES

Our matching contributions to the 401(k) plan were $0.6 million, $0.6 million and $0.3 million for the years 

ended December 31, 2018, 2017 and 2016, respectively. Our matching contributions are accrued and recorded as 
expense during each payroll period. Effective January 1, 2017, we changed the 401(k) plan to include an auto
enrollment feature, increased our match from 25% of the first 8% to 50% of the first 8% and reduced the vesting 
period from six years to three years.

In Mexico, we maintain an annual savings fund, which matches the employee contribution each week, based 

on the Mexican statutory maximum of 13% of actual minimum salary rates. The savings fund period runs from 
November to October each year, and is distributed to employees in full, during the first week of November each 
year. For the years ended December 31, 2018, 2017 and 2016, we incurred matched savings expense of $0.2 million, 
$1.3 million and $0.6 million, respectively.

In Turkey, we maintain a retirement fund that is based on a formula of annual salary multiplied by the number 
of years of service with us. We accrue a retirement fund liability for this each month. As of December 31, 2018 and 
2017, we accrued $1.0 million and $1.5 million, respectively, based on the service periods of eligible employees 
greater than one year.

During the fourth quarter of 2017, we recorded a net tax expense of $0.1 million (net of valuation allowance)
related to the enactment of the Tax Cuts and Jobs Act (Tax Reform). The expense was primarily related to applying 
the federal income tax rate change to certain of our deferred tax liabilities, and the realization of a benefit from our 
alternative minimum tax credit carryover.  This provisional amount was subject to adjustment during the 
measurement period of up to one year following the December 2017 enactment of Tax Reform, as provided by SEC
guidance. 

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 discussed above was
unchanged.

Tax Reform enacted a new minimum tax on U.S. companies’ foreign operations called Global Intangible Low 

Tax Income (GILTI). Beginning in 2018, GILTI provisions will be applied providing an incremental tax on low

F-34

TPI COMPOSITES, INC. AND SUBSIDIARIES 

Notes to Consolidated Financial Statements

taxed foreign income. The GILTI provisions require us to include in our U.S. income tax return foreign subsidiary
earnings in excess of an allowable return on the foreign subsidiary’s tangible assets. We have made a policy election
to account for any ongoing impacts of GILTI tax in the period in which it is incurred. At December 31, 2018, we
provided no net amount for the federal income tax impacts of GILTI, made up of $12.1 million in income taxes
related to the GILTI inclusion, which were fully offset by net operating loss carryforwards, and the income tax
expense increase in the rate reconciliation related to the GILTI inclusion was reduced by the release of the 
previously provided valuation allowance on U.S. deferred tax assets.  

Undistributed earnings of certain of our foreign subsidiaries amounted to approximately $111.1 million at 

December 31, 2018, and we consider those earnings reinvested indefinitely. As a result of the deemed mandatory 
repatriation provision pursuant to Tax Reform, we included undistributed earnings in income subject to U.S. tax at 
reduced tax rates in 2017. In addition, we recognized GILTI income reduced by net operating losses in 2018 as part 
of the changes from Tax Reform. As a result, we do not have material basis differences related to cumulative 
unremitted earnings for U.S. income tax purposes.   

The income tax provision includes U.S. federal, state, and local taxes, Turkey, China and Mexico taxes
currently payable and those deferred because of temporary differences between the financial statement and the tax
bases of assets and liabilities. The components of the income tax provision for the years ended December 31 are as

The valuation allowance as of December 31, 2018 primarily relates to certain state net operating losses 

(NOLs) that we believe do not meet the more-likely-than-not criteria for recording the related benefits.

During 2018, we released the valuation allowance recorded against deferred tax assets reported in the United 
States. The release of this valuation allowance resulted in the recognition of a non-cash tax benefit of $10.8 million 
for the year. Additionally, during 2018, there was an increase in the valuation allowance of $0.6 million primarily
related to state NOLs. 

We have U.S. federal NOL of approximately $25.8 million, state NOLs of approximately $118.5 million, 
foreign NOLs of approximately $14.6 million and foreign tax credits of approximately $1.9 million available to
offset future U.S. and China taxable income. The U.S. federal and state net operating loss carryforwards expire in
varying amounts through 2038 and the foreign tax credits expire in 2026. We also have Turkey investment tax 
incentives of approximately $0.3 million which do not expire and foreign NOLs that expire in 2023.

Sections 382 and 383 of the Internal Revenue Code of 1986, contain rules that limit the ability of a company that 

undergoes an “ownership change” to utilize its net operating loss and tax credit carry forwards and certain built-in 
losses recognized in years after the “ownership change.” An “ownership change” is generally defined as any change in 
ownership of more than 50% of a corporation’s stock over a rolling three-year period by stockholders that own (directly 
or indirectly) 5% or more of the stock of a corporation, or arising from a new issuance of stock by a corporation. If an 
ownership change occurs, Section 382 generally imposes an annual limitation on the use of pre-ownership change 
NOLs to offset taxable income earned after the ownership change. The annual limitation is equal to the product of the 
applicable long-term tax exempt rate and the value of our stock immediately before the ownership change. This annual 
limitation may be adjusted to reflect any unused annual limitation for prior years and certain recognized built-in gains 
and losses for the year. In addition, Section 383 generally limits the amount of tax liability in any post-ownership 
change year that can be reduced by pre-ownership change tax credit carryforwards.

In June of 2018, we experienced an ownership change.  The pre-ownership change NOLs existing at the date of 

change of $47.7 million are subject to an annual limitation. We do not believe that the Section 382 and 383 annual 
limitation will materially impact our ability to utilize the tax attributes that existed as of the date of the ownership
change. Certain of these NOLs may be at risk of limitation in the event of a future ownership change.

We recognize the impact of a tax position in its financial statements if that position is more-likely-than-not to 
be sustained on audit, based on the technical merits of the position. We disclose all unrecognized tax benefits, which
includes the reserves recorded for uncertain tax positions on filed tax returns and the unrecognized portion of 
affirmative claims. Our policy regarding uncertain tax positions is to recognize potential accrued interest and 
penalties related to unrecognized tax benefits as a component of income tax expense. As of December 31, 2018, we 
had not identified any unrecognized tax benefits.

We operate in and file income tax returns in various jurisdictions in China, Mexico, Turkey, the U.S., 

Denmark and Switzerland, which are subject to examination by tax authorities.

FASB ASC Topic 280, Segment Reporting, establishes standards for the manner in which companies report 
financial information about operating segments, products, services, geographic areas and major customers. In managing
our business, management focuses on growing our revenues and earnings in select geographic areas serving primarily 
the wind energy market. We have operations in the United States, China, Turkey and Mexico. Our operating segments 
are defined geographically as the United States, Asia, EMEAI and Mexico. Financial results are aggregated into four 
reportable segments based on quantitative thresholds. All of our segments operate in their local currency except for the
Mexico and Asia segments, which both include a U.S. parent company.

Note 19. Adjustments to Previously Reported Financial Statements from the Adoption of an Accounting 
Pronouncement   

As discussed in Note 1, Summary of Operations and Significant Accounting Policies, Topic 606 and ASUs
2016-15 and 2016-18 were adopted by us as of January 1, 2018 with retrospective application to January 1, 2016 
through December 31, 2017. The December 31, 2017 balance sheet retrospectively restated for the adoption of 
Topic 606 presented below differs from that previously disclosed in the 2018 Quarterly Reports on Form 10-Q due
to the correction of the income tax effect of the adoption of Topic 606. The effect of these changes are decreases in
total assets, total liabilities and total stockholders’ equity at December 31, 2017 of $10.8 million, $1.5 million and 
$9.3 million, respectively.    

The following tables summarize the effects of adopting Topic 606 and ASU 2016-18 had on our previously 

reported financial statements.

The primary effects of the adoption of Topic 606 on our consolidated balance sheet include 1) amounts being
recognized as revenue for work performed as production takes place over time as contract assets, which differs from
the prior practice of including the balances in inventory; 2) no longer reporting inventory held for customer orders or 
deferred revenue since revenue is now being recognized over the course of the production process, and before the
product is delivered to the customer; 3) that contract liabilities are reported for amounts collected from customers in
advance of the production of products, similar to our prior practice of recording customer deposits; 4) the impact of 
the retrospective adjustment on deferred income taxes; and 5) the cumulative amount of the effect to prior periods’
net income related to the adoption of Topic 606 through December 31, 2017 is reflected in retained earnings.

Notes to Consolidated Financial Statements

As part of our adoption of Topic 606, we have elected to use the following practical expedients:

•

•

•

for completed contracts that have variable consideration, we have used the transaction price at the date 
on which the contract was completed, rather than estimating amounts for variable consideration in each 
comparative reporting period. 

for modified contracts, we did not separately evaluate the effects of the contract modifications before 
the beginning of the earliest period presented. Instead, we reflected the aggregate effect of all of the 
modifications that occur before the beginning of the earliest period presented in determining the 
transaction price, identifying the satisfied and unsatisfied performance obligations, and allocating the 
transaction price to the performance obligations. 

for all periods presented before the date of initial application, we did not disclose the amount of the 
transaction price allocated to remaining performance obligations, nor an explanation of when we expect 
to recognize that amount as revenue.

The impact of applying the above practical expedients may change the period of revenue recognition but not 

the total amount to be recognized under the contract; therefore, we believe that the application of the practical 
expedients is not material to the comparability of the information presented above and the accounting and financial 
reporting related to the adoption of Topic 606.
