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, TPI or we). The Company was founded in 1968 and has been producing composite wind blades since 2001. The Company is incorporated in the State of Delaware. Bankruptcy Proceedings On August 11, 2025 (the “Petition Date”), TPI Composites, Inc. and certain of its direct and indirect subsidiaries (such subsidiaries, together with the Company, collectively, the “Company Parties” or the “Debtors”) each filed voluntary petitions for relief under chapter 11 of title 11 of the United States Bankruptcy Code (the “Bankruptcy Code” and such cases, the “Chapter 11 Cases”) in the United States Bankruptcy Court for the Southern District of Texas (the “Bankruptcy Court”). The Debtors also filed a motion seeking approval of procedures for the sale of all or any of the Debtors’ assets pursuant to section 363 of the Bankruptcy Code. Documents filed on the docket of, and other information related to, the Chapter 11 Cases are available at https://restructuring.ra.kroll.com/TPIComposites. Documents and other information available on such website are not part of this document and shall not be deemed incorporated by reference in this document. The Company continues to operate its business as “debtor-in-possession” under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and the orders of the Bankruptcy Court. Discontinued Operations On September 10, 2025, the Company consummated the sale and transfer of 100% of its ownership interests of the Company’s two Turkish subsidiaries (the “Türkiye business”), which was approved by the Bankruptcy Court. The transaction involved the sale and transfer of the assets and operations of two wind blade manufacturing facilities and a field service inspection and repair business in Izmir, Türkiye on an “as-is” basis, including the assumption of the entire liabilities and debt position of the Turkish subsidiaries by the purchaser. The Türkiye business comprised the majority of the Company’s EMEA segment. The Company determined that the sale of the Türkiye business represented a strategic shift that had a major effect on the Company’s operations and financial results. Accordingly, the historical results of our Türkiye business have been presented as discontinued operations in our consolidated Statements of Operations and consolidated Balance Sheets. On June 30, 2024, we completed the divestiture of our wholly-owned subsidiary, TPI, Inc. (the Automotive subsidiary). The Automotive subsidiary was engaged in the development, commercialization and implementation of the Company’s automotive industry related products. The Automotive subsidiary was previously classified as held for sale in the Company’s consolidated balance sheets as of December 31, 2023. The divestiture constituted a strategic shift as the Company will focus entirely on executing its core business in the wind industry going forward, and accordingly, the historical results of our Automotive subsidiary have been presented as discontinued operations in our consolidated statements of operations and consolidated balance sheets. Unless specifically noted or otherwise indicated, all information set forth in this Annual Report on Form 10-K relates to the Company as it existed as of December 31, 2025 and the following discussion reflects continuing operations only. Overview We are an independent manufacturer of composite wind blades for the wind energy market with a manufacturing footprint currently in the U.S., Mexico, and India. We enable certain of the industry’s leading wind turbine original equipment manufacturers (OEM) to outsource the manufacturing of a portion of their wind blades through our footprint of advanced manufacturing facilities strategically located to serve large 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. We have entered into supply agreements pursuant to which we dedicate capacity at our facilities to our customers and manufacture wind 6 blade sets (each set consisting of three wind blades) for our customers. This collaborative dedicated supplier model provides us with contracted volumes that generate revenue visibility, drive capital efficiency and allow us to produce wind blades at a competitive 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. Our wind blade manufacturing business accounted for approximately 95%, 97%, and 96% of our total net sales for each of the years ended December 31, 2025, 2024 and 2023, respectively. Financial Information about Segments and Geographic Areas We divide our business operations into three geographic operating segments - (1) the U.S., (2) Mexico, and (3) India as follows: •Our U.S. segment includes (1) the manufacturing of wind blades at our Newton, Iowa facility which restarted production in the second half of 2025, (2) wind blade inspection and repair services in the U.S., and global corporate support functions including (3) our advanced engineering center in Kolding, Denmark, which provides technical and engineering resources to our manufacturing facilities, (4) our engineering center in Berlin, Germany and (5) our corporate headquarters in Scottsdale, Arizona. •Our Mexico segment includes (1) the manufacturing of wind blades at our three facilities in Juárez, Mexico and one facility in Matamoros, Mexico and (2) wind blade inspection and repair services in Mexico. •Our India segment includes (1) the manufacturing of wind blades at our facility in Chennai, India, and (2) wind blade inspection and repair services in India. For additional information regarding our discontinued operations, and operating segments and geographic areas, see Note 4 – Discontinued Operations, and Note 23 – Segment Reporting, respectively, of the Notes to Consolidated Financial Statements included in Part II, Item 8 of this Annual Report on Form 10-K. Business Strategy The key elements of our business strategy are as follows: •Successfully complete the sale of substantially all of our assets pursuant to section 363 of the Bankruptcy Code. We continue to operate our business as debtors-in-possession and following a competitive marketing process, in March 2026, we agreed to terms in separate transactions to sell substantially all of the Debtors’ assets pursuant to section 363 of the Bankruptcy Code, subject to various closing conditions. •Capitalize on the long-term trends of decarbonization of the electric sector. We believe we are well-positioned to participate and benefit from the long-term trend of decarbonization of the electric sector. Although regulatory uncertainty, including uncertainty related to the current U.S. administration's actions regarding clean energy, as well as permitting, siting and transmission challenges in the U.S. and Europe has tempered demand for wind energy in the near term, we expect demand for renewable energy, and wind energy in particular, will continue to grow in the long term due to a multitude of factors, including: increased demand for all forms of energy to power data centers and the electrification of industrial production and transportation; increased cost competitiveness of wind energy compared to fossil fuel generated electricity; increased demand from corporations and utility providers for renewable energy; the need for energy independence and security and recent international policy initiatives designed to promote the growth of renewable energy. We believe our strategic footprint of manufacturing facilities will allow us to capitalize on the expected long-term growth of wind energy. 7 •Leverage our manufacturing footprint to serve the North American market. We believe we are well-positioned with our strategic footprint, and we believe we have optimized this footprint to serve our key customer in key markets. We utilize our strengths in composites technology and manufacturing, combined with our collaborative dedicated supplier model to provide our customers with an efficient solution for their expansion in large onshore wind markets. •Continue to ensure that wind energy remains competitive with other energy sources. We continue to work with our customers on wind blade models that maximize the capture of wind energy so that the levelized cost of energy for wind energy remains competitive with other energy sources such as solar and natural gas. We also continue to utilize our advanced technology, regional manufacturing facilities strategically located to cost effectively serve large wind markets and ability to source materials globally at competitive costs to deliver high-performing, composite wind blades. Our collaborative engineering approach allows us to integrate our customer’s design requirements with cost-efficient, replicable and scalable manufacturing processes that reduce manufacturing cycle times, new line and factory start up times and new blade model transition times. We also continue to work with our customers to minimize the impacts of inflation, including increases in the cost of materials and production in a manner that further strengthens our customer relationships and mitigates the impact to our margins. •Focus on continuing innovation. We have a history of innovation in advanced composite technologies and production techniques and use several proprietary technologies related to wind blade manufacturing. With this culture of innovation and a collaborative “design for manufacturability” approach, we continue to address increasing physical dimensions, demanding technical specifications and strict quality control requirements for our customers’ most advanced wind blades. Wind Blade Manufacturing Operations and Process We have developed significant expertise in advanced composite technology and we 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 103,000 wind blades since 2001 from our continuing and discontinued operations 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 over 80 meters in length across our manufacturing 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 efficiency. 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 competitive cost for 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. 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. However, one of our customers sources 8 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 this customer, we have fewer controls and remedies to mitigate raw material and supply chain risks and disruptions relating to such raw materials for such customer. 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 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 serial 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 have also developed BladeAssureTM, a process that integrates advanced technologies to ensure world-class wind blade quality and operational efficiency. These technologies include AI-aided vision solutions, selective automation and robotics, advanced sensors, and inspection technologies. These advancements are designed to document, verify, automate, and prevent manufacturing inconsistencies and abnormalities. We implemented BladeAssureTM at the majority of our manufacturing facilities in 2025. We focus on safety, consistency, quality control, lean principles and technological innovation across our facilities, using hands-on training methods and employing repeatable manufacturing processes, to drive down costs through operational improvements and efficiencies and eliminating waste. 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. 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 During the year ended December 31, 2025, we manufactured wind blades for our two primary customers, Vestas Wind Systems A/S (“Vestas”) and GE Vernova, Inc. (“GE Vernova”), which are some of the world’s largest wind turbine manufacturers. Moving forward, the Company expects to focus its core wind blade business on supporting its operations with a single customer, GE Vernova. In our collaborative dedicated supplier model, our customers are incentivized to maximize the volume of wind blades purchased due to lower pricing at higher purchase volumes. Historically, our supply agreements generally contain liquidated damages provisions in the event of late delivery. Typically, our supply agreements with our customers provide us with downside protection 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 9 specified amount typically triggers higher pricing. Some of our supply agreements also provide for annual sales price reductions reflecting assumptions regarding improvements in our manufacturing efficiency and increases in 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. However, one of our customers sources all of the critical raw materials that we use to produce such customers' 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 the customer. Orders in excess of annual commitments may 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. Research and Development We conduct research and development in close collaboration with our customers and suppliers in areas of design for manufacturing and deployment of innovative manufacturing processes, including automation, advanced materials, and emerging product quality inspection tools. We have partnered with the U.S. Department of Energy, national laboratories, universities, suppliers, and our customers to innovate through cost-sharing and funded development of advanced manufacturing, sustainability (including material recycling) and other innovative programs. During the year ended December 31, 2025, we initiated projects on a variety of funded efforts with universities, government laboratories and private industry partners that include inspection technologies, additive manufacturing of modular wind blades, as well as manufacturing automation applying recycled materials to ensure movement toward a more sustainable, carbon neutral future. We continue to collaborate in national consortia and study a broad range of wind energy related technologies with our customers and wind energy owner operators. One such set of activities is an internal and external collaborative development program to create a comprehensive multi-layered artificial intelligence (AI) powered vision system that supports production metrics such as cycle-time and labor headcount and will also drive quality by reducing infusion defects and ensuring uniform resin process across the entire surface of the wind turbine blade. We continue to expand our IP portfolio through funding internal research and development. Our manufacturing technology team is leveraging our in-house knowledge and expertise in modeling, data analysis, machine learning, artificial intelligence, and optical vision systems to implement an engineering configuration that allows for an effective roll-out of a closed-loop blade manufacturing system which we expect will positively impact quality, labor productivity and cycle-time. We are expanding and diversifying our Model-Based Manufacturing tools and techniques to cover broad technical areas including design, manufacturability, finishing processes and factory level repairs. 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. We have an advanced engineering center based in Berlin, Germany which focuses on blade design, tooling, materials and process technology development. In addition, we have an advanced engineering center based in Kolding, Denmark which provides technical and engineering resources to our manufacturing facilities and our customers. 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, prototyping, testing, optimization and volume production capabilities. We also encourage our associates 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 we intend to continue to seek opportunities for product development programs that could create recurring revenue and increase our overall profitability over the long term. 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 Vernova) and other independent wind 10 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 or will be located, such as Indutch Composites Technology Pvt. Ltd. in India. We also compete with vertically integrated wind turbine OEMs that manufacture their own wind blades. The principal competitive factors in the wind blade market include reliability, total delivered cost, manufacturing capability, product quality, engineering capability and on-time delivery of wind blades. We believe we compete favorably with our competitors with respect to each of these factors. However, while we have successfully competed with Chinese wind blade manufacturers for years, their recent aggressive push to expand their presence in Europe and other regions outside of North America, supported by the Chinese government, has added to the challenging competitive environment outside of the U.S. Our ability to compete will depend to a great extent upon our ongoing performance in the areas of manufacturing capability, total delivered costs, on-time delivery and product quality. Competitive advantages in the wind blade service market include total delivered cost, speed of response, local footprint, repair quality, competitive labor pricing and capacity to work across regions as demand adapts to business seasonality. Our ability to improve our product and service offerings, 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. 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, Türkiye, India and China, 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, associates, 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, associates, 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, 2025 and 2024, our backlog for wind blades and related wind products totaled $114.8 million and $237.6 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. 11 Department of Labor and comparable agencies in Mexico, India and individual U.S. states. In addition, our manufacturing operations in Mexico and India are subject to those countries’ wage and price controls, currency exchange control regulations, investment and tax laws, laws restricting our ability to repatriate profits, trade restrictions and laws that may restrict foreign investment in certain industries. Some of these laws have only been recently adopted or are subject to further rulemaking or interpretation, and their impact on our operations, including the cost of complying with these laws, is uncertain. We believe that our operations currently comply, in all material respects, with applicable laws and regulations. Further, as a U.S. corporation, we are subject to The Foreign Corrupt Practices Act of 1977 (FCPA), which generally prohibits U.S. companies and their intermediaries from making improper payments to foreign officials for the purpose of obtaining or keeping business. Although FCPA enforcement was recently paused by the U.S. federal government, we plan to continue to comply with the provisions of the FCPA. 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 and the India Prevention of Corruption Act. In August 2022, the U.S. Congress passed the Inflation Reduction Act of 2022 (IRA) which effectively extended the Production Tax Credit for Renewable Energy (PTC), which provides owners of wind turbines with a credit against its U.S. federal income tax obligations based on the amount of electricity generated by the wind turbine. In addition, a new advanced manufacturing production tax credit (AMPC) was created that can be claimed for the domestic production and sale of clean energy components, such as wind blades. We plan to utilize the AMPC at our Newton, Iowa manufacturing facility, which restarted production in the second half of 2025. However, the passing of the One Big Beautiful Bill Act (OBBBA) in July 2025 resulted in these wind energy tax credits being phased out earlier than expected, which could have a material impact on our Iowa facility. As of December 31, 2025, we generated and recognized approximately $7.9 million of tax credit receivables related to the AMPC based on the production of eligible wind blades at our Iowa facility during the year. We continue to monitor U.S. government policy and actions for any changes that could have adverse impacts on our business. At the state level, as of December 31, 2024, 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). Customs Review The CBP is currently reviewing certain of the wind blade models that are manufactured at our facilities in Mexico pursuant to the Uyghur Forced Labor Prevention Act (“UFLPA”). As a result of these reviews, CBP has restricted the importation of these wind blades into the U.S. while the matter remains under investigation. Although we are confident that our wind blade supply chain does not source materials from the Xinjiang Uyghur Autonomous Region of China, the UFLPA establishes a rebuttable presumption that goods mined, produced, or manufactured wholly or in part in the Xinjiang Uyghur Autonomous Region of China, or by certain identified entities, are made with forced labor and are therefore prohibited from entry into the U.S. unless the importer can demonstrate otherwise to the satisfaction of CBP. Because of the current CBP actions, a substantial portion of the wind blades manufactured at our Mexico facilities are unable to be imported into the U.S. market. The inability to import these wind blades has significantly disrupted, and may continue to disrupt, our supply chain, reduce available inventory for U.S. customers, delay deliveries, and result in lost sales. In addition, these CBP reviews have required and may continue to require significant management attention, internal resources, and legal and compliance costs as we work to respond to CBP’s inquiries and further demonstrate compliance with applicable laws. The outcome and duration of the CBP reviews are uncertain. If we are unable to satisfactorily resolve the matter, CBP may continue to detain, exclude, or seize affected wind blades, which could further restrict our ability to serve customers in the U.S. and may require us to modify our sourcing, manufacturing, or supply chain practices. Any prolonged disruption in our ability to import wind blades into the U.S., or any adverse findings by CBP, will have a further, material adverse effect on our business, financial condition, and results of operations. 12 Human Capital As of December 31, 2025, we employed more than 9,600 full-time associates, approximately 800 of whom were in the U.S., 7,800 in Mexico, 900 in India and 100 in other countries. Certain of our associates in our manufacturing facility in Matamoros, Mexico are represented by labor unions. We believe that our relations with our associates are generally good. Our human capital strategy focuses on creating an exceptional associate experience and ensuring that we foster a learning culture where our associates 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, have a strong sense of inclusion and belonging, and are committed to the Company, their teams, and the jobs they perform based on our most recent associate engagement surveys which continue to show strong commitment from our associates. Our associate engagement is due in part to a strong sense of purpose given our role in the broader renewable energy supply chain. We believe associate engagement and feelings of inclusion and belonging translates into a strong quality focus and orientation. When we select new persons to join our team, we ensure that the individuals have high levels of adaptability in addition to the skills needed for the role. Our associates 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 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: •general awareness EHS training •ergonomics training •compliance training •hazard-specific training as required for the job or task •fire hazard and prevention training •hazardous material training •equipment-specific safety training •safety incident and corrective action training Inclusion We aspire to create an environment that recognizes and celebrates the benefits that come with a diverse workforce and strive to create a culture of inclusion where everyone has a true sense of belonging and feels they can be themselves in the workplace. 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. We facilitate an annual talent review process in all regions and 13 functional teams to promote the internal development and promotion of internal talent. We have enjoyed high participation in associate surveys, high engagement levels against industry normative data, and facilitated an inclusion survey in 2025, 2024 and 2023. 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 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. 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.
