PART I

Item 1. Business

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 is incorporated in Delaware.

Overview

We are the 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) 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 is 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 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 (each set consisting 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 provide field service inspection and repair services to our OEM customers and wind farm owners and operators. Our field service inspection and repairs services include diagnostic, repair and maintenance service offerings for wind blades that have been installed on wind turbines located at wind farms. Our field service inspection and repair services can be performed up-tower, where a blade technician performs these services in the air or from the wind turbine tower on a wind turbine blade, or down tower, where a blade is first removed from a wind turbine and these services are performed on the ground at the wind farm site or in a repair facility.

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 June 2021, we extended our supply agreement with Proterra, Inc. (Proterra) to supply Proterra Catalyst® composite bus bodies through December 2024. In 2019, we made a capital investment of approximately $11.5 million to develop a highly automated manufacturing line for the electric vehicle market within our Warren, Rhode Island facility to enable us to further develop our technology, create defensible product and process intellectual property (IP) and demonstrate our capability to manufacture composite components cost effectively at automotive volume rates. In 2021, we began a production program to manufacture a composite component for an electric vehicle manufacturer using this automated production line and have commenced production of additional composites components for this manufacturer in 2022. We manufactured approximately 26,000 production components in 2021 and anticipate manufacturing 25,000 production components in the first half of 2022. We continue to expand our manufacturing capabilities and have received orders with a major OEM to produce approximately 450,000 production components in 2022 and approximately 1,000,000 in 2023.

Our wind blade and precision molding and assembly systems manufacturing businesses accounted for approximately 95%, 96%, and 96% of our total net sales for each of the years ended December 31, 2021, 2020 and 2019, respectively. As of February 24, 2022, our wind and transportation supply agreements provide for minimum aggregate volume commitments from our customers of approximately $2.2 billion and encourage our customers to purchase additional volume up to, in the aggregate, a total contract value of approximately $3.5 billion through the end of 2024.

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 75,000 wind blades since 2001 with a strong, long-term 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 approximately 80 meters in length 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. Using continuous improvement principles, we can customize each manufacturing step, from raw materials to finished products. This 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 secure volumes that we believe will be required to fulfill our customers’ wind blade commitments for fixed prices with limited contractual price adjustment provisions. A portion of our raw materials are subject to price volatility, such as the resins and carbon reinforcements used in our manufacturing processes. During 2021, there have been both significant price increases and supply constraints with respect to resins and carbon fiber, which are key raw materials that we use to manufacture our products, as well as increases in logistics costs to obtain raw materials. These increases in raw materials and related logistics adversely affected our results of operations by approximately $38 million for the year ended December 31, 2021.

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. Our largest customer, however, sources all of the critical raw materials that we use to produce such customers' wind blades. Since we do not source procurement of these raw materials for our largest customer, we have fewer controls and remedies to mitigate raw material and supply chain risks and disruptions relating to such raw materials. For example, we experienced production delays and reduced production volumes in 2021 at our Matamoros, Mexico and Izmir, Turkey manufacturing facilities due to carbon and other raw material shortages that were sourced by a customer.

Precision Molding and Assembly Systems

Over the last decade, we have produced hundreds of precision molding and assembly systems, ranging from 30 meters to approximately 80 meters in length, to support our global operations. In 2020, we transitioned our North American precision molding and assembly system production capabilities to a new facility in Juárez, Mexico, which serves customers globally. Our precision molding and assembly systems have been used to build tens of thousands of wind blades worldwide.

6

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 each 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 fiber, 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 continuous improvement principles, 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 Supply Agreements

Our current wind blade customers, which include Vestas, GE Wind, Nordex, and ENERCON GmbH (ENERCON), are some of the world’s largest wind turbine manufacturers. According to data from Bloomberg, our customers represented approximately 37% of the global onshore wind energy market, approximately 76% of that market excluding China, and 89% of the U.S. onshore wind turbine market over the three years ended December 31, 2020, 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 24, 2022, our existing wind blade supply agreements provide for minimum aggregate volume commitments from our customers of approximately $2.2 billion and encourage our customers to purchase additional volume up to, in the aggregate, a total contract value of approximately $3.5 billion through the end of 2024, 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.

Our supply agreements with our customers generally provide downside protection for us through minimum annual volume commitments, as well as encourage our customers to maximize the volume of wind blades they purchase from us, since purchasing less than a specified amount typically triggers higher pricing. Some of our supply agreements also provide for annual sales price reductions reflecting assumptions regarding increases in our

7

manufacturing efficiency and productivity. We work to continue to drive down or minimize the impact of increases in 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. Similarly, we typically share any raw material price increases with our customers. Our largest customer, however, sources all of the critical raw materials that we use to produce its wind blades and this customer assumes 100% of any such raw material price increases or decreases. 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.

Vestas

In 2014, we entered into a supply agreement with Vestas to supply wind blades from our manufacturing facility in Dafeng, China. Based on the success of this manufacturing arrangement, we expanded our relationship with Vestas through additional supply agreements to manufacture wind blades at our manufacturing facilities in Turkey, Matamoros, Mexico, Yangzhou, China and Chennai, India. In December 2021, we extended our supply agreement with Vestas at one of our Izmir, Turkey plants for an additional year through December 2023. We consolidated our manufacturing footprint for Vestas in China at the end of 2021 by stopping production at our Dafeng, China facility and agreeing to add four new manufacturing lines to our Yangzhou, China manufacturing facility. Each of the supply agreements with Vestas provide for a minimum number of wind blade sets to be purchased by Vestas 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 Vestas for each of the years under the supply agreements. Additionally, we have manufactured some of the model-specific tooling that we use to produce wind blades for Vestas. If either party commits a material breach of the supply agreement, the non-breaching party may terminate the supply agreement if the breach is not remedied or if the parties have not mutually agreed to plan for cure within 30 days after notice of breach has been given.

GE Wind

We have multiple supply agreements with GE Wind to manufacture wind blades from two manufacturing facilities in Juárez, 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. In August 2018, GE Wind agreed to extend our existing supply agreement for one of our Mexico manufacturing facilities by two years to 2022 and increased the number of wind blade manufacturing lines in that facility from three to five. In July 2020, GE Wind agreed to extend our existing supply agreement in one of our Mexico plants by two years to 2022 and added one additional wind blade manufacturing line in Mexico to provide blades for GE Wind’s turbine technologies in North America in 2021. We ceased production of GE Wind blades at our Iowa facility during the fourth quarter of 2021. Unless otherwise terminated or renewed, our supply agreements with GE Wind in Mexico are in effect until the end of 2022. 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.

Nordex

We supply wind blades to Nordex from our manufacturing facilities in Turkey, India and Matamoros, Mexico. In Matamoros, we took over a facility from Nordex, pursuant to a 3-year supply agreement. If the supply agreement for the Matamoros manufacturing facility is not extended, then Nordex will resume management and operation of the Matamoros wind blade manufacturing facility at the end of the 3-year term. Each of the supply agreements with Nordex provide for a minimum number of wind blade sets to be purchased by Nordex each year during the term, and we commit to dedicate a specific number of manufacturing lines to Nordex for each of the years under the supply agreements.

8

Other Supply Agreements

We have a supply agreement in Turkey with ENERCON. With respect to this supply agreement, we have agreed to dedicate capacity for a set number of wind blades for each calendar year during the term of the agreement in exchange for a commitment to purchase minimum annual volumes of wind blade sets. Unless otherwise terminated, this supply agreement remains in effect for a period of several years and either party may terminate the supply agreement upon a material breach by the other party which goes uncured. This supply agreement contains provisions that allow for our customer to purchase less volume in later years of this supply agreement, 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— Some of our supply agreements with our customers are subject to early termination and volume reductions at the discretion of our customers, and any early termination of or reduced volumes of wind blades purchased under these agreements would materially harm our business, financial condition and results of operations” 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 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 of advanced manufacturing and other innovative programs. In 2021, we began a collaboration with the University of Maine pursuant to a grant from the U.S. DOE’s Advanced Manufacturing Office to develop a rapid, low-cost additive manufacturing solution (3D printing) for fabricating large, segmented wind blade molds. Additionally, we participate on collaborative programs as a working member of the Institute for Advanced Composite Manufacturing Innovation (IACMI), a US DOE National Network of Manufacturing Innovation consortium. Specifically, this effort includes new material systems focused on creating an economical solution to end-of-life reclamation of materials for reuse and recycling. This work includes cost sharing of engineering and laboratory support to develop new process technologies.

We employ a highly experienced workforce of engineers in various facets of our business, from 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.

In July 2019, we acquired certain IP and hired a team of engineering resources from the EUROS group, based in Berlin, Germany. This team of technical experts focuses on blade design, tooling, materials and process technology development. This acquisition strengthened our technical capabilities in support of our global operations and growth. In addition, we established an advanced engineering center in Kolding, Denmark which provides technical and engineering resources to our manufacturing facilities and our customers.

Competition

The wind blade market is highly concentrated, competitive and subject to evolving customer needs and expectations. Our competitors include LM Wind Power (a subsidiary of GE Renewable Energy) and 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.

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.

Competitive advantages in the wind blade service market include speed of response, local footprint, repair quality, competitive labor pricing and capacity to work across regions as demand adapts to the business seasonality. Our competitors include certain of our wind OEM customers, and a broad range of independent wind blade service companies. We have proven strong in many of these criteria and our ability to remain competitive will depend on such factors, including strengthening our response time, adding and managing labor resources, sourcing materials globally at competitive rates while further expanding into new countries, and offering additional value-added engineering support and technical solutions.

The transportation and automotive supply industry is highly competitive, and our composite solutions compete against alternative materials and a broad range of competitive suppliers. Our ability to remain competitive will depend on time to market, continuing to provide a lower upfront investment for our customers, and providing superior performance attributes with our composite solutions.

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 and components, are ideally suited for our advanced composite technology because of the benefits derived from weight reduction, corrosion resistance, strength, durability and lower upfront capital costs. These benefits should allow us to develop structural composite solutions to assist our customers in developing electric vehicles, including light, medium and heavy-duty trucks, buses and automobiles with clean propulsion systems or in meeting new and developing fuel economy 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 Juárez, Mexico manufacture products for customers in the transportation market using, in some cases, 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 last-mile delivery as well as automated people mover systems for airports. In November 2017, we signed a five-year supply agreement with Proterra to supply Proterra Catalyst® composite bus bodies. In June 2021, we extended our supply agreement with Proterra through December 2024.

10

In 2019, we made a capital investment of approximately $11.5 million to develop a highly automated manufacturing line for the electric vehicle market within our Warren, Rhode Island facility to 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. In 2021, we began a production program to manufacture a composite component for an electric vehicle manufacturer using this automated production line and have commenced production of additional components for this manufacturer in 2022. We manufactured approximately 26,000 production components in 2021 and anticipate manufacturing an additional 25,000 production components in the first half of 2022. We continue to expand our manufacturing capabilities and have received orders with a major OEM to produce approximately 450,000 production components in 2022 and approximately 1,000,000 in 2023.

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 IP rights, including trademarks, copyrights and patents issued, filed and applied-for in a number of jurisdictions, including the U.S., Germany, 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 and not on our IP alone. 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 IP 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, 2021 and 2020, our backlog for wind blades and related wind products totaled $813.1 million and $1,197.7 million, respectively. Our backlog includes purchase orders issued in connection with our supply agreements. We generally record a purchase order into backlog when the following requirements have been met: a signed 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 wind 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 Environmental Protection Agency (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

11

intermediaries from making improper payments to foreign officials for the purpose of obtaining or keeping business. As a U.S. corporation with global operations, we are also subject to foreign antibribery laws and regulations in the countries where we conduct business, including the U.K. Bribery Act.

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 U.S., 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 was to be phased down over the term of the PTC extension. Specifically, the PTC was 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 was to be reduced by 20% per year in 2017, 2018 and 2019, respectively. In December 2019, Congress extended the PTC through the end of 2020 and increased the rate from 40% to 60% for projects that either commenced construction or met certain safe harbor requirements by the end of 2020 and are commissioned by the end of 2024. In December 2020, Congress extended the PTC through the end of 2021, continuing the rate of 60% for projects that either commenced construction or met certain safe harbor requirements by the end of 2021 and are commissioned by the end of 2025. Although we believe that the onshore wind market will continue to grow over the long term, the expiration of the PTC at the end of 2021 has created uncertainty in the near term resulting in decreased demand for our wind blades in 2021 compared to 2020. We are monitoring legislative and regulatory policy proposals to extend or expand tax credits in the U.S. to promote wind energy.

At the state level, as of December 31, 2021, 30 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 2050).

In addition, there are also increasing regulatory efforts globally to promote renewable power. In December 2020, the European Union (EU) agreed to reduce EU greenhouse gas emissions by at least 55% by 2030, compared to 1990 levels. Similarly, in December 2020, China announced its goal to reach carbon neutrality by 2060, and in November 2021, India targeted to increase its renewable energy capacity to 500 gigawatts by 2030 and to reach carbon neutrality by 2070. Additionally, Turkey enacted Law No. 5346 in 2005, which was recently amended and extended in January 2021, to promote renewable-based electricity generation within their domestic electricity market through feed-in- tariffs and purchase obligations for distribution companies requiring purchases from certified renewable energy producers.

Human Capital

As of December 31, 2021, we employed over 14,000 full-time employees, approximately 600 of whom were located in the U.S., 1,400 in China, 6,300 in Mexico, 4,100 in Turkey and 1,600 in India. Certain of our employees in Turkey and at our manufacturing facilities in Matamoros, Mexico are represented by labor unions. We believe that our relations with our employees are generally good.

Our human capital strategy focuses on creating an exceptional employee experience and ensuring that we foster a learning culture where our employees want to grow with us. Our primary focus areas of our human capital strategy are as follows:

Culture

We believe our unique culture is a key strategic advantage for us. Our associates are highly engaged and committed to the Company, their teams, and the jobs they perform based on our most recent employee engagement surveys. This strong employee engagement is due in part to a strong sense of purpose given our role in the broader

12

renewable energy supply chain. We believe strong employee engagement translates into a strong quality focus and orientation. It is through the efforts of our approximately 14,000 employees at year-end 2021 that we have been able to continue to achieve high levels of performance. When we select new persons to join our team, we ensure that the individuals have high levels of commitment and adaptability in addition to the skills needed for the role. Our employees embrace our core values of safety, operational excellence, commitment, integrity and leadership. Our team members bring our values to life by applying their diverse backgrounds and skillsets to the jobs they are performing, demonstrating high discretionary effort, and embracing our values in their day-to-day lives.

Safety

Safety is our most important and first core value. We strongly believe that all accidents are preventable and that every associate should return at the end of their shift to their families in the same healthy condition in which they showed up for work. To help drive these beliefs it is our goal to continuously improve our zero-harm culture and implement a global behavior-based safety (BBS) program resulting in zero unsafe behaviors. All of our manufacturing facilities have safety management systems in place that cover their associates and activities. We ensure the safety of our associates to support our zero-harm culture in a variety of ways, starting with safety education. Safety education is the foundation for our other safety measures. Associates receive regular training on environmental, health and safety (EHS) related topics. This training includes but is not limited to:

Diversity, Equity and Inclusion

We value diversity in all forms, especially diversity of thought, and aspire to create an environment that recognizes and celebrates the benefits that come with a diverse workforce. We know that diversity of our employee population makes us better and strive to continue to improve and act with intention in these areas.

As a global business, we have an incredible opportunity to benefit from the diversity we have in our Company. We can and will do more to maximize the positive impact that diversity, equity, inclusion, and a feeling of belonging can bring. We believe that this and the rest of our vision statement for diversity, equity and inclusion is a solid representation of what we believe in, are committed to, and how we will hold associates and leaders accountable. We recognize that one of our greatest areas of opportunity is to increase the representation of women and overall racial and ethnic diversity at all levels of leadership as we add more talent to our leadership levels.

Talent

We market open jobs across multiple platforms such as our website, LinkedIn, internal postings and local job boards to ensure that our candidate pool is as diverse as possible. We promote having diversity on the interviewing and selection panel to ensure different points of view are considered as part of the final selection process. We enjoy high levels of retention across all of our geographies. Our overall turnover rate has continued to decline over the past three years on a global basis. We facilitate an annual talent review process in all regions and functional teams to promote the internal development and promotion of internal talent. We have enjoyed high participation in employee surveys, high engagement levels against industry normative data, and also facilitated a COVID-19 and diversity equity and inclusion survey in 2021.

Environmental, Health and Safety

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

13

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. We are not aware of any pending environmental compliance or remediation matters that are reasonably likely to have a material adverse effect on our business, financial position or results of operations. However, failure by us to comply with applicable environmental and other requirements could result in fines, penalties, enforcement actions, third party claims, remediation actions, and could negatively impact our reputation with customers. We have adopted environmental, health and safety policies outlining our commitment to environmental responsibility and accountability and our desire to eliminate unsafe behaviors in the workplace. These policies apply to the Company as a whole, and our vendors and suppliers and are available on our website. We have a company-wide focus on safety and have implemented a number of measures to promote workplace safety. Customers are increasingly focused on safety records in their sourcing decisions due to increased regulations to report all incidents that occur at their sites and the costs associated with such incidents.

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 Business

A significant portion of our business is derived from a small number of customers, and three 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 supply agreement renewals from these customers could materially harm our business.

Substantially all of our revenues are derived from three wind blade customers. Vestas, GE Wind and Nordex accounted for 40.4%, 24.7% and 22.4%, respectively, of our total net sales for the year ended December 31, 2021, and 49.7%, 23.4% and 15.3%, respectively, of our total net sales for the year ended December 31, 2020, and 46.1%, 25.7% and 16.1%, respectively, of our total net sales for the year ended December 31, 2019. Accordingly, we are substantially dependent on continued business from our current wind blade customers. 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 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, and our reserves for warranty expenses might not be sufficient to cover all future costs.

Defects in the wind blades we manufacture are unpredictable and an inherent risk in manufacturing technically advanced products that involve a significant amount of manual labor and processes. Defects may arise from multiple causes, including design, engineering, materials, manufacturing and components failures as well as deficiencies in our manufacturing processes. 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 experienced wind blade 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. Wind blades that we have manufactured have also failed in the field. Any wind blade 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 supply agreements or business relationships with current or new customers. Any of the foregoing could materially harm our business, operating results and financial condition.

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. 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.

16

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 2020 and into 2021, we undertook model transitions at several of our facilities for various customer demands. In 2020, we had several manufacturing lines in transition which adversely impacted our revenue and profitability. We currently expect to have manufacturing lines in transition during 2022 which could adversely affect our revenue and profitability in 2022. We typically share transition costs with the customer in connection with these changing customer demands, but any sharing is usually 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.

We have experienced, and could in the future experience, quality or operational issues in connection with plant construction, expansion or assumption 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 five manufacturing facilities in Mexico, one in Turkey, one in Yangzhou, China and one in Chennai, India. The construction of new plants and the expansion or assumption of existing plants involves significant time, cost and other risks. We generally expect our plants to generate losses in their first 12 to 18 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, defects or issues with product tooling, 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. Any delays or difficulties in plant startup, expansion or assumption 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. For example, in 2019, we experienced construction and startup delays with respect to our new manufacturing facility in Yangzhou, China. These delays resulted in us paying liquidated damages of $7.8 million to one of our customers in 2019 and 2020. In 2021, we experienced significant production delays at the Matamoros, Mexico manufacturing facility that we took over from Nordex in July 2021, which adversely impacted our profitability and financial condition.

Some of our supply agreements with our customers are subject to early termination and volume reductions at the discretion of our customers, and any early termination of or reduced volumes of wind blades purchased under these agreements could materially harm our business, financial condition and results of operations.

Our supply agreements expire between the end of 2021 and the end of 2024. Some of our 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. Our 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. The amount of the annual purchase requirements typically decline in the later years of our supply agreements. Our customers may not continue to maintain supply agreements with us in the future. For example, Vestas did not renew its Dafeng, China supply agreement, and GE did not renew its Iowa supply agreement, both of which expired at the end of 2021. If one or more of our customers terminate, or reduce the number of manufacturing lines and volumes of wind blades purchased, or fail to renew their supply agreements with us, it may materially harm our business, financial condition and results of operations.

17

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, which typically provide producers of wind energy with favorable prices for wind generated electricity, to unsubsidized, 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 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 U.S., our business is still heavily dependent upon the demand for wind energy in the U.S. and any downturn in demand for wind energy in the U.S. 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 U.S., China, Mexico, Turkey and India. Although a majority of our manufacturing facilities are located outside of the U.S., historically more than half of the wind blades that we produced were deployed in wind farms located within the U.S. Our Iowa and Mexico manufacturing facilities manufacture wind blades that are generally deployed within the U.S. In addition, many of our wind blades are exported from our China, Turkey and India manufacturing facilities to the U.S. In addition, tariffs imposed on components of wind turbines from China, including wind blades, has had a negative impact on demand for our wind blades manufactured in our Chinese manufacturing facilities. Consequently, demand for wind energy and our wind blade sales could be adversely affected by a variety of reasons and factors, and any downturn in demand for wind energy in the U.S. could materially harm our business. We expect that demand for wind turbine blades in 2022 will remain at similar levels or decline compared to 2021 due in large part to continued regulatory uncertainty in the U.S. regarding whether the PTC will be extended or other clean energy legislation is enacted.

We have recently experienced significant price increases and supply constraints of raw materials and components that are critical to our manufacturing needs, and we may continue to, or in the future, experience such price increases and supply constraints, which may hinder our ability to perform under our supply agreements and adversely impact our profitability and financial condition.

We rely upon third parties for raw materials, such as fiberglass, carbon fiber, 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. During 2021, there have been both significant price increases and supply constraints with respect to resin and carbon fiber, which are key raw materials that we use to manufacture our products, as well as increases in logistics costs to obtain raw materials. The resin price increases and supply constraints are due to a multitude of factors, including the extreme cold weather in Texas in February 2021, fires at resin manufacturing facilities in China and unplanned maintenance outages at resin manufacturing facilities in Europe. Carbon fiber prices have increased primarily due to the cost of raw material inputs as well as increased global demand for carbon fiber across multiple industries. Although we are able to a pass a portion of these cost increases onto our customers, these raw material price and logistics cost increases adversely affected our results of operations by approximately $38 million for the year ended December 31, 2021.

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, closely monitor and manage inventory and acquire raw materials and components as needed and with consideration to lead time factors. Due to significant international demand for these raw materials from many industries, and extended logistics lead times, we may be unable to acquire sufficient quantities or secure a stable supply for our manufacturing needs. Our largest customer sources all of the critical raw materials that we use to produce its wind blades and in some instances, our customers source the purchase of certain key raw materials and components. Since we do not source the procurement of these raw materials for our largest customer, we have fewer controls and remedies to mitigate

18

raw material and supply chain risks and disruptions relating to these raw materials. For example, we experienced production delays and reduced production volumes in 2021 at our Matamoros, Mexico and Izmir, Turkey manufacturing facilities due to carbon and other raw material shortages that were sourced by a customer.

In 2021, we procured approximately 22% of our raw materials from China so any ocean logistic delays, weather events, strikes, other force majeure events or geopolitical developments impacting China could disrupt our supply chain. 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.

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:

In 2021, we experienced a decline in demand for our wind turbine blades due primarily to regulatory uncertainty regarding whether the PTC would be extended beyond 2021 in the U.S., which adversely impacted our operating results. We expect that demand for wind turbine blades in 2022 will remain at similar levels or decline compared to 2021. 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.

19

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:

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 supply agreements or penalties for regulatory non-compliance, any of which could materially harm our business, operating results and financial condition.

20

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 U.S., China, Mexico, Turkey, and India. Since the third quarter of 2016, we have commenced operations at five new manufacturing facilities in Mexico, one in Turkey, one in Yangzhou, China and one in Chennai, India. For the years ended December 31, 2021, 2020 and 2019, approximately 90%, 89% and 88%, respectively, of our net sales were derived from our international 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:

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, diversify our product and service offerings 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, diversifying our product and service offerings and adding 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 or engage us to provide field service inspection and repair services or ancillary products and services. Our collaborative dedicated supplier

21

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 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 continue to 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 and related product and service offerings, 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 traditional (i.e. thermal) and other renewable energy sources. Decreases in the prices of electricity from traditional or 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. 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. 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.

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 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. The competitive environment in the wind energy industry recently has become more challenging primarily due to ongoing regulatory uncertainty and supply chain constraints and significant raw material price increases. This challenging environment may lead to further consolidation in the industry, which could lead to us having even fewer customers. In addition, a significant percentage of wind turbine OEMs, including all 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. Some 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 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 supply agreements with potential new and existing customers may be materially harmed.

22

Various legislation, regulations and incentives that are expected to support the growth of wind energy in the U.S. 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 has been dependent in part upon governmental support through certain incentives including federal tax incentives and state RPS programs and may not be economically viable if a large number of these incentives are not continued. Government-sponsored tax incentive programs including the PTC, and the Investment Tax Credit (ITC) have supported the U.S. growth of wind energy. The PTC and ITC were extended for an additional year through the end of 2021. Although we believe that the onshore wind market will continue to grow over the long term, the expiration of the PTC at the end of 2021 has created uncertainty in the near term resulting in decreased demand for our wind blades in 2021 compared to 2020. We are monitoring legislative and regulatory policy proposals to extend or expand tax credits in the U.S. to promote wind energy.

Because of the long lead times necessary to develop wind energy projects, any uncertainty or delay in reinstituting the PTC and ITC or adopting, extending or renewing other incentives promoting wind energy 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 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 U.S. 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.

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. We have experienced startup challenges and incurred significant losses to date in connection with the supply of bus bodies to Proterra. 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.

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.

Risks Related to Our Business as a Whole

Our business, operations and financial condition during the years ended December 31, 2021 and 2020 were adversely affected by the COVID-19 pandemic and we cannot estimate the duration of the COVID-19 pandemic and our business may be adversely affected in the future if the COVID-19 pandemic persists.

The COVID-19 pandemic adversely affected our business and operations during the years ended December 31, 2021 and 2020. During the first quarter of 2020, our China manufacturing facilities were adversely impacted by the COVID-19 pandemic in the form of reduced production levels and COVID-19 related costs associated with the health and safety of our associates and non-productive labor. During the second quarter of 2020, all of our manufacturing facilities with the exception of our China manufacturing facilities and our Rhode Island

23

manufacturing facility were required to temporarily suspend production or operate at reduced production levels due primarily to certain applicable government-mandated stay at home orders in response to the COVID-19 pandemic, demands from certain of our labor unions to suspend or reduce production and general safety concerns of our associates. By the end of the second quarter of 2020, most of our manufacturing facilities had returned to operating at or near normal production levels. During the third quarter of 2021, our manufacturing facility in Yangzhou, China was required to temporarily suspend production due to a COVID-19 outbreak in Yangzhou City. We may be required to reinstate temporary production suspensions or volume reductions at our other manufacturing facilities to the extent there is a resurgence of COVID-19 cases in the regions where we operate or there is an outbreak of positive COVID-19 cases in any of our manufacturing facilities.

Our financial position, revenue, operating results, profitability and cash flows 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, profitability and cash flows have varied in the past and are likely to vary significantly from quarter to quarter in the future. The factors that are likely to cause these variations include:

As a result, our revenue, operating results, profitability and cash flows 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

24

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. To the extent our future revenues and expenses are generated outside of the U.S. 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, 2021 and 2020, our capital expenditures were $38.9 million and $65.9 million, respectively, including assets acquired under finance leases in 2021 and 2020 of $1.8 million and $0.2 million, respectively. We have recently entered into lease agreements with third parties to lease new manufacturing facilities in China, India and Mexico. We plan to make continued investments in our Turkey, Mexico, and China facilities. 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 or access capital to acquire new businesses. 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 our business 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.

Our business and reputation could be adversely impacted by any violations of the FCPA, the U.K. Bribery Act, and other foreign anti-corruption laws.

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. Other countries in which we operate also have anti-corruption laws, some of which prohibit improper payments to government and non-government persons and entities, and others extend their application to activities outside their country of origin. We 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, particularly 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 policies, procedures and controls designed to ensure compliance with the 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 or other anti-corruption laws, 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 similar laws, which could provide them with a competitive advantage in some jurisdictions.

25

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.

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:

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. We were not in compliance with certain financial covenants of our senior secured credit facility as of September 30, 2021, primarily due to the Mexico production delays, increased raw material costs and constraints described above. On November 8, 2021 (the Waiver Effective Date), we and the lenders that are parties to the senior secured credit facility executed a limited waiver pursuant to which the lenders agreed to temporarily waive our compliance with this financial covenant from the Waiver Effective Date through December 8, 2021. If we are not able to pay our debts as they become due, we could be in default under our senior secured 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

26

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 IP rights, including patents, trademarks and copyrights, but much of our most important IP rights consist of trade secrets and know-how and effective IP protection may be unavailable, limited or outside the scope of the IP rights we pursue in the U.S. and in foreign countries such as China where we operate. Although we strive to protect our IP 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 IP rights, but it is possible that a customer, supplier, employee or contractor might breach the agreement, intentionally or unintentionally. 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 IP 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 IP 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.

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’s Occupational Safety and Health Administration, 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 March 2019, we entered into a settlement agreement with the Iowa Department of Labor pursuant to which we agreed to make a settlement payment of $0.1 million and to implement certain safety enhancements at our Newton, Iowa manufacturing facility to fully resolve this matter.

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.

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.

27

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 48% of our workforce as of December 31, 2021, are covered by collective bargaining agreements. Our collective bargaining agreement for our Turkey facilities are in effect through the end of 2022.

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 an increase in their wage rate and an annual bonus. In February 2019, our manufacturing production employees in Matamoros, Mexico, who were represented by a labor union, went on strike also demanding an increase in their hourly wage rate and the payment of an annual bonus. During this strike, our Matamoros manufacturing facility stopped production for several weeks until we reached a revised agreement with our labor union. We amended this Matamoros collective bargaining agreement to adjust the salaries and bonuses payable to our associates for calendar year 2022 that are covered by this agreement. This collective bargaining agreement is in effect through March 2023.

In July 2021, we took over a manufacturing facility from Nordex in Matamoros, Mexico pursuant to a 3-year supply agreement. We have a collective bargaining agreement for the associates at this facility that is in effect through April 2023 and we expect this collective bargaining agreement will be amended during the first half of 2022.

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, or other challenges with negotiating and extending our collective bargaining agreements with our unionized employees, 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, breaches of data security and phishing and ransomware attacks could disrupt our operations. Any significant disruption or breach may materially harm our business, operating results or financial condition.

Risks Related to Our Series A Preferred Stock

Holders of our Series A Preferred Stock may exercise influence over us, including through their ability to designate a member of our board of directors.

In November 2021, we issued 350,000 shares of Series A Preferred Stock to certain funds affiliated with Oaktree Capital Management, L.P. (the Series A Preferred Stockholders) for an aggregate purchase price of $350 million. The Series A Preferred Stockholders are entitled to designate one representative to be appointed to our board of directors so long as 33% of the Series A Preferred Stock originally issued remains outstanding. Notwithstanding the fact that all directors are subject to fiduciary duties to us and subject to applicable law, the interests of the director designated by the Series A Preferred Stockholders may differ from the interests of holders of our common stock or of our other directors.

Although the Series A Preferred Stockholders do not have any voting rights or rights to convert such preferred shares into shares of common stock, we must obtain the prior written consent of holders of a majority of the outstanding shares of Series A Preferred Stock for, among other things: (i) amending our organizational documents to the extent such amendment has an adverse effect on the Series A Preferred Stockholders, (ii) effecting any change

28

of control, liquidation event or merger or consolidation of us unless the entirety of the applicable redemption price is paid with respect to all the then issued and outstanding Series A Preferred Stock (iii) increasing or decreasing the number of authorized shares of Series A Preferred Stock, (iv) making certain material acquisitions or dispositions or entering into joint ventures or similar transactions, (v) incurring indebtedness except for indebtedness incurred under our existing loan facilities and agreements so long as the total amount of such indebtedness does not exceed $80 million, and (vi) committing to any capital expenditures or agreements to construct or acquire new manufacturing facilities, and (vii) certain other specified actions.

As a result, the Series A Preferred Stockholders have the ability to influence the outcome of certain matters affecting our governance and capitalization. The sponsors of the Series A Preferred Stockholders are in the business of making or advising on investments in companies, including businesses that may directly or indirectly compete with certain portions of our business, and they may have interests that diverge from, or even conflict with, those of our other stockholders. They may also pursue acquisition opportunities that may be complementary to our business, and, as a result, those acquisition opportunities may not be available to us. Our obligations to the Series A Preferred Stockholders could also limit our ability to obtain additional financing or increase our borrowing costs, which could have an adverse effect on our results of operations and financial condition.

Our Series A Preferred Stock has rights, preferences, and privileges that are not held by, and are preferential to, the rights of holders of our common stock, which could adversely affect our liquidity and financial condition.

The Series A Preferred Stockholders have certain liquidation, dividend and redemption rights requiring us, among other things, to repurchase their shares of Series A Preferred Stock under specified circumstances, and these rights are senior to the rights of holders of our common stock. We may not be able to generate sufficient cash flow from our operations to satisfy our dividend, liquidation and redemption obligations to the Series A Preferred Stockholder and could impact our liquidity and reduce the amount of cash available for working capital, capital expenditures, growth opportunities, acquisitions, and other general corporate purposes. Our obligations to the Series A Preferred Stockholders could also limit our ability to obtain additional financing or increase our borrowing costs, which could have an adverse effect on our financial condition. If we fail to meet our dividend, liquidation redemption and other material covenant obligations owing to the Series A Stockholders, the Series A Stockholders are entitled to additional rights and preferences, including an increased dividend rate, additional control rights over the management of our business and the right to require us to pursue a financing or other transaction to repay all outstanding dividend and redemption obligations owing to the Series A Preferred Stockholders.

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:

29

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, 2021, we had 37,180,004 shares of common stock outstanding. All shares can now be sold, subject to any applicable volume limitations under federal securities laws. We may issue debt or equity securities in other registered or unregistered convertible debt or equity offerings.

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, 2021, we had outstanding options to purchase 998,126 shares of our common stock, 636,606 restricted stock units and 378,661 performance stock units to our employees and non-employee directors. From time to time, we expect to grant additional options and other stock awards. We also issued warrants to purchase 4,666,667 shares of common stock at an exercise price of $0.01 per share to the Series A Preferred Stockholders. The Series A Preferred Stockholders may exercise their warrants at any time during the five-year term of the warrants and the number of shares issuable upon exercise of the warrants is subject to customary adjustments upon the occurrence of certain events such as stock splits, reclassifications, combinations, dividends, distributions, mergers and other similar events. 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.

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

30

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.

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.

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 to holders of our common stock, will be at the discretion of the board of directors, junior to the rights of the Series A Preferred Stockholders to receive dividends, and 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 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 of this Annual Report on Form 10-K.

Certain of our subsidiaries are limited in their ability to declare dividends without first meeting statutory restrictions of China, including retained earnings as determined under Chinese-statutory accounting requirements. Until 50% ($26.7 million) of registered capital is contributed to a surplus reserve, our China operations can only pay dividends equal to 90% of after-tax profits (10% must be contributed to the surplus reserve). Once the surplus reserve fund requirement is met, our China operations can pay dividends equal to 100% of after-tax profit assuming other conditions are met. As of December 31, 2021, the amount of the surplus reserve fund was $10.0 million.

Key Trends Affecting our Business

We have identified the following material trends affecting our business:

35

COMPONENTS OF RESULTS OF OPERATIONS

Net Sales

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

Cost of Goods Sold

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

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

General and Administrative Expenses

General and administrative expenses primarily relate to the unallocated portion of costs incurred at our corporate headquarters and our research facilities and include salaries, benefits and other personnel related costs for

36

employees engaged in research and development, engineering, finance, internal audit, information technology, human resources, business development, global operational excellence, global supply chain, in-house legal and executive management. Other costs include outside legal and accounting fees, risk management (insurance), share-based compensation and certain other administrative and global resources costs.

The unallocated research and development expenses incurred at our Warren, Rhode Island location as well as at our Kolding, Denmark advanced engineering center and our Berlin, Germany engineering center are also included in general and administrative expenses. For the years ended December 31, 2021, 2020 and 2019, total research and development expenses totaled $1.0 million, $1.0 million and $1.0 million, respectively.

Loss on Sale of Assets and Asset Impairments

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

Restructuring Charges

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

Other Income (Expense)

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

Income Taxes

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

KEY METRICS USED BY MANAGEMENT TO MEASURE PERFORMANCE

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