Fiscal Year Reporting

In this Annual Report on Form 10-K, when we refer to our fiscal years, we state “fiscal” and the year, as in “fiscal 2026”, which refers to our fiscal year ended March 31, 2026. The Company reports interim financial information for 13-week periods, except for the first quarter, which always begins on April 1, and the fourth quarter, which always ends on March 31. The four quarters in fiscal 2026 ended on June 29, 2025, September 28, 2025, December 28, 2025, and March 31, 2026, respectively. The four quarters in fiscal 2025 ended on June 30, 2024, September 29, 2024, December 29, 2024, and March 31, 2025, respectively.

History

EnerSys and its predecessor companies have been manufacturers of industrial batteries for over 125 years. Morgan Stanley Capital Partners teamed with the management of Yuasa, Inc. in late 2000 to acquire from Yuasa Corporation (Japan) its reserve power and motive power battery businesses in North and South America. We were incorporated in October 2000 for the purpose of completing the Yuasa, Inc. acquisition. On January 1, 2001, we changed our name from Yuasa, Inc. to EnerSys to reflect our focus on the energy systems nature of our businesses.

In 2004, EnerSys completed its initial public offering (the “IPO”) and the Company’s common stock commenced trading on the New York Stock Exchange, under the trading symbol “ENS”.

Key Developments

There have been several key stages in the development of our business, which explain to a significant degree our results of operations over the past several years.

In March 2002, we acquired the reserve power and motive power business of the Energy Storage Group of Invensys plc. (“ESGI”). Our successful integration of ESGI provided global scale in both the reserve and motive power markets. The ESGI acquisition also provided us with a further opportunity to reduce costs and improve operating efficiency.

Between fiscal years 2003 through 2026, we made thirty-seven acquisitions around the globe. There were no significant acquisitions in fiscal 2023 or 2024. On July 26, 2024, the Company completed the acquisition of all of the equity of Bren-Tronics Defense LLC for $206.4 million in cash consideration, as set forth in the stock purchase agreement. Bren-Tronics Defense LLC, headquartered in Commack, New York, is a leading manufacturer of highly reliable portable power solutions, including small and large format lithium batteries and charging solutions, for military and defense applications. The financial results contributed from this business are reported within our Specialty line of business.

Our Customers

We serve over 10,000 customers in over 100 countries, on a direct basis or through our distributors. We are not overly dependent on any particular end market. Our customer base is highly diverse, and no single customer accounts for more than 10% of our revenues.

Our Energy Systems customers consist of both global and regional customers. These customers are in diverse markets including telecommunication and broadband services, data centers, electric utilities, emergency lighting, renewable energy, and industrial utilities.

Our Motive Power products are sold to a large, diversified customer base. These customers include material handling equipment dealers, forklift and heavy truck original equipment manufacturers (“OEMs”) and end users of such equipment. End users include manufacturers, distributors, warehouse operators, retailers, airports, mine operators and railroads.

Our Specialty products are utilized in transportation, primarily in premium automotive and large over-the-road trucking, aerospace and defense and medical markets. The products are sold globally to OEMs, distribution partners, vehicle fleets and directly to government entities such as the United States of America, Germany and the United Kingdom.

Our New Ventures energy storage and management systems are sold to customers who own or manage commercial real estate and own or manage retail operations. The systems are sold globally through our direct sales channel. We received our first system orders in fiscal year 2024 from our launch customer in Canada and other customers based in the United States.

Distribution and Services

We distribute, sell and service our products throughout the world, principally through company-owned sales and service facilities, as well as through independent manufacturers’ representatives. Our company-owned network allows us to offer high-quality service, including preventative maintenance programs and customer support. Our warehouses and service locations enable us to respond quickly to customers in the markets we serve. We believe that the extensive industry experience of our sales organization results in strong long-term customer relationships.

Manufacturing and Raw Materials

We manufacture and assemble our products at manufacturing facilities located in the Americas, EMEA and Asia. With a view toward projected demand, we strive to optimize and balance capacity at our battery manufacturing facilities globally, while simultaneously minimizing our product cost. By taking a global view of our manufacturing requirements and capacity, we believe we are better able to anticipate potential capacity bottlenecks and equipment and capital funding needs.

The primary raw materials used to manufacture our products include lead, plastics, steel and copper. We purchase lead from a number of leading suppliers throughout the world. Because lead is traded on the world’s commodity markets and its price fluctuates daily, we periodically enter into hedging arrangements for a portion of our projected requirements to reduce the volatility of our costs.

Competition

The industrial energy storage market is highly competitive both among competitors who manufacture and sell industrial energy storage solutions and batteries, energy management solutions, dynamic fast chargers for EVs, and among customers who purchase these solutions. Our competitors range from development stage companies to large domestic and international corporations. Certain of our competitors produce energy storage products utilizing technologies or chemistries different from our own. We compete primarily on the basis of reputation, product quality, reliability of service, delivery lead time and price. We believe that our products and services are competitively priced.

Energy Systems

We compete principally with East Penn Manufacturing, Exide Technologies (Stryten), Fiamm, SAFT, Hoppecke, New Power, C&D Technologies Inc., Vertiv, OmniOn Power,Yuasa, Amphenol, Delta Electronics, as well as Chinese producers.

Motive Power

Our primary global competitors in traditional lead-acid include East Penn Manufacturing, Exide Technologies (Stryten), Hoppecke, Eternity, Midac, Sunlight and TAB, as well as a number of domestic Chinese manufacturers.

Additionally, while lithium-ion battery technology in the motive power space has traditionally been relegated to smaller material handling applications, we have seen the entrance of a number of companies into larger battery types, acting as lithium cell packagers or integrators of cells sourced primarily from Asia. The integrators include forklift original equipment manufacturers either directly or through partnership with other entities.

Specialty

We compete globally within the transportation, aerospace and defense markets and specialized lithium technologies used in these critical applications. Our thin plate pure lead (TPPL) technology is a significant player in the applications using absorbed glass materials (AGM). Our major competitors in AGM technology are Clarios, East Penn Manufacturing, Exide Technologies (Stryten), Fiamm, C&D Technologies, Inc., Banner and Atlas. In the Aerospace and Defense specialized markets our main competitors are EaglePicher and SAFT.

New Ventures

We compete globally within the energy storage system and DC fast charging market with specialized lithium technologies offering solutions that combine energy management for commercial and retail buildings and dynamic fast charging for EVs. Our primary competitors are Jule, Tritium, and ABB.

Warranties

Warranties for our products vary by application and geographically and by product type and are competitive with other suppliers of these types of products. Generally, our Energy Systems product warranties range from one to twenty years, our Motive Power product warranties range from one to five years and from one to four years for Specialty transportation batteries. The length of our warranties is varied to reflect regional characteristics and competitive influences. In some cases, our warranty period may include a pro rata period, which is typically based around the design life of the product and the application served. Our warranties generally cover defects in workmanship and materials and are limited to specific usage parameters.

Intellectual Property

We have numerous patents and patent licenses in the United States and other jurisdictions but do not consider any one patent to be material to our business. From time to time, we apply for patents on new inventions and designs, but we believe that the growth of our business will depend primarily upon the quality of our products and our relationships with our customers, rather than the extent of our patent protection.

We believe we are the leader in TPPL technology. We believe that a significant capital investment would be required by any party desiring to produce products using TPPL technology for our markets.

Table of Contents

We own or possess exclusive and non-exclusive licenses and other rights to use a number of trademarks in various jurisdictions. We have obtained registrations for many of these trademarks in the United States and other jurisdictions. Our various trademark registrations currently have durations of approximately 10 to 20 years, varying by mark and jurisdiction of registration and may be renewable. We endeavor to keep all of our material registrations current. We believe that many such rights and licenses are important to our business by helping to develop strong brand-name recognition in the marketplace.

Seasonality

Our business generally does not experience significant quarterly fluctuations in net sales as a result of weather or other trends that can be directly linked to seasonality patterns, although transportation and power electronics can experience seasonality in colder months. Despite that, historically our fourth quarter is our best quarter with higher revenues and generally more working days while our second quarter is the weakest due to the summer holiday season in Western Europe and North America.

Product and Process Development

Our product and process development efforts are focused on the creation of new energy storage products, and integrated power systems and controls. We allocate our resources to the following key areas:

•the design and development of new products;

•optimizing and expanding our existing product offering;

•waste and scrap reduction;

•production efficiency and utilization;

•capacity expansion without additional facilities; and

•quality attribute maximization.

Employees

At March 31, 2026, we had approximately 9,682 employees. Of these employees, approximately 31% were covered by collective bargaining agreements. Employees covered by collective bargaining agreements that expire in the next twelve months were approximately 6% of the total workforce. The average term of these agreements is 1 year, with the longest term being 4 years. We consider our employee relations to be good. We did not experience any significant labor unrest or disruption of production during fiscal 2026.

Environmental Matters and Climate Change Impacts

We are committed to the preservation of natural resources, protection of the environment, and training our employees to perform their duties accordingly. In the manufacture of our products throughout the world, we process, store, dispose of and otherwise use large amounts of hazardous materials, especially lead and acid. As a result, we are subject to extensive and evolving environmental, health and safety laws and regulations governing, among other things: the generation, handling, storage, use, transportation and disposal of hazardous materials; emissions or discharges of hazardous materials into the ground, air or water; and the health and safety of our employees. Compliance with these laws and regulations results in ongoing costs. Failure to comply with these laws and regulations, or to obtain or comply with required environmental permits, could result in fines, criminal charges or other sanctions by regulators. From time to time, we have had instances of alleged or actual noncompliance that have resulted in the imposition of fines, penalties and required corrective actions. Our ongoing compliance with environmental, health and safety laws, regulations and permits could require us to incur significant expenses, limit our ability to modify or expand our facilities or continue production and require us to install additional pollution control equipment and make other capital improvements. In addition, private parties, including current or former employees, can bring personal injury or other claims against us due to the presence of, or their exposure to, hazardous substances used, stored, transported or disposed of by us or contained in our products.

Environmental and safety certifications

Twenty-six of our facilities in the Americas, EMEA and APAC are certified to ISO 14001. ISO 14001 is a globally recognized, voluntary program that focuses on the implementation, maintenance and continual improvement of an environmental management system and the improvement of environmental performance. Thirteen facilities in EMEA and APAC are certified to ISO 45001. The ISO 45001 is a globally recognized occupational health and safety management systems standard.

Climate change impacts

The potential impact of climate change on our operations is uncertain. The changing climate may result in new and erratic weather patterns, increases in the frequency or severity of storms, increased and decreased temperatures and rising sea levels. As discussed elsewhere in this Annual Report on Form 10-K, including in Item 1A. Risk Factors, our operating results are significantly influenced by weather, and major changes in historical weather patterns could have a notable impact on our future operating results. For example, if climate change results in drier weather and more accommodating temperatures over a significant period of time, we may be able to increase our productivity, which could positively impact our revenues and gross margins. Conversely, if climate change results in a greater amount of rainfall, snow, ice or other less accommodating weather conditions, we could experience reduced productivity, which could negatively impact our revenues and gross margins. Further, while an increase in severe weather events, such as hurricanes, tropical storms, blizzards and ice storms, can create a greater amount of emergency restoration service work (an area of potential revenue generation), it often also can result in delays or

other negative consequences for our manufacturing operations, or challenges to the consistent delivery of materials from our supply chain or of our products to distributors, which could negatively impact our financial results. Climate change may also affect the conditions in which we operate, and in some cases, expose us to potentially increased liabilities associated with those environmental conditions. Concerns about climate change could also result in new regulations, regulatory actions or requirements to invest in energy efficiency, any of which could result in increased costs associated with our operations. We are aware of the various regulatory developments on climate (and other sustainability-related) disclosures from multiple jurisdictions, including the European Union’s Corporate Sustainability Reporting Directive (CSRD). While we are following the progression of these rules, we are pleased to note that we are well prepared to meet their conditions at or before EnerSys would be required to do so. We have released comprehensive Sustainability Reports since 2022, which are aligned with GRI, SASB and most recently ISSB, standards. For FY25 we also published a comprehensive index aligned with CSRD standards Included in these reports, we announced key, measurable environmental, social, and governance goals and objectives aimed at advancing progress in sustainability, reducing our environmental footprint and creating an inclusive and empowering workplace for all employees. We also issued our third Task Force of Climate Related Financial Disclosures (TCFD) Report in May 2025. As part of our growing sustainability commitment, we announced during fiscal year 2022 that we joined the United Nations Global Compact, Alliance to Save Energy, the U.S. Department of Energy’s Better Plants Program (through which we committed to reducing our energy intensity by 25% over the next 10 years (from a calendar year 2020 baseline)and the United Nations CEO Water Mandate. Since calendar 2023, we have submitted to the CDP. In 2025 this includes section on Climate Change, Water and Supply chain. We have conducted and published a climate risk analysis and have published our Scope 1, 2 and 3 emissions annually. We have set net-neutral goals for Scopes 1 (2040) and 2 (2050) and have marked consistent decreases in both overall carbon emissions as well as carbon intensity. In October, 2024, we published our Climate Action Plan Roadmap, detailing our plans to achieve our Scope 1 and 2 related climate goals. For fiscal year 2026, sustainability metrics were incorporated into the annual goals of our CEO and certain elements of employee compensation.

We strive to operate our facilities in a manner that protects the environment and the health and safety of our employees, customers and communities. We have established required sustainability training for identified employees and incorporate climate and other sustainability considerations into our formal decision-making processes. We have implemented company-wide environmental, health and safety policies and practices, which includes monitoring, training and communication of these policies.

Quality Systems

We utilize a global strategy for quality management systems, policies and procedures, the basis of which is ISO 9001:2015, a worldwide recognized quality standard. We believe in the principles of this standard and reinforce the same by requiring mandatory certification to the ISO 9001 standard for all manufacturing locations globally. We also focus on plant certifications that serve specific industries such as AS9100 (Aerospace), ISO 13485:2016 (Medical Devices), ISO/TS 22163:2017 (Rail), IATF 16949:2016 (Automotive) and ISO 19443 (Nuclear). We have also acquired our first Lithium-Ion product certification in accordance with ISO 26262 (Product Safety).

This strategy enables us to provide consistent quality products and services to meet our customers’ needs.

Human Capital Management

EnerSys believes that human capital management, including attracting, developing and retaining a high-quality workforce, is critical to our long-term success. We are committed to fostering a culture of innovation, collaboration and continuous learning, driving sustainable growth and long-term value creation for our shareholders, employees and stakeholders alike.

Creating a positive employee experience throughout the talent lifecycle is key to a highly stable and engaged workforce and a critical element in meeting strategic business goals. Our Board of Directors, through the Compensation Committee and the Nominating and Corporate Governance Committee, retains oversight of our human capital management process, including talent development, employee retention, material aspects of employee compensation, as well as our People Index as an indicator of cultural health. The Nominating and Corporate Governance Committee reports on human capital matters at each regularly scheduled Board of Directors meeting. The most significant human capital measures, objectives and initiatives include the following:

Health, Safety, and Wellness: Our fundamental responsibility as an employer is to provide a safe and healthy workplace for all our employees. This undertaking is explained further in our Safety and Health Policy. Our health and safety programs are designed around global standards with appropriate variations addressing the multiple jurisdictions and regulations, specific

hazards and unique working environments of our manufacturing and production facilities, service centers and headquarter operations. Above all else, we are dedicated to the safety and well-being of our employees.

Everywhere for Everyone: We believe that success, in part, is built on a variety of perspectives and we are committed to fostering a workplace that values individual talent, supports professional growth and ensures ample opportunities for all employees. In both our recruiting and performance processes we measure talent on their merit in terms of knowledge, skills and experience and how well they reflect our company values. We do not tolerate discrimination or harassment of any nature. Individuals are evaluated based on merit, without concern for race, color, religion, national origin, citizenship, marital status, gender (including pregnancy), gender identity, gender expression, sexual orientation, age, disability, veteran status, or other characteristics protected by law. We are committed to providing equal opportunities to every member of our workforce. We cultivate our inclusive culture with robust business resource groups.

Giving Back: Through our Giving Back program,EnerSys is strongly committed to being an outstanding corporate citizen on a global basis in all the countries and communities where we do business. This commitment is reflected in a strong ethic for charitable contributions, endorsement of community activities, encouraging employees to give freely of their own time to serve on boards or committees for non-profit organizations and supporting educational programs in schools and colleges.

We established a Giving Back Committee to assist the Company in its philanthropic endeavors that support the communities in which we live and work. Additionally, we regularly sponsor volunteer events and fundraising campaigns, to encourage our employees to give back to our communities.

People Development and Performance Management: We are committed to developing a qualified and motivated workforce to power our continued innovation and growth. We provide opportunities for employees to gain the skills and knowledge they need to advance in the Company and fulfill their personal career goals.

We encourage continuous feedback between employees and managers, and employees receive formal development feedback from their manager through a quarterly 1:1 review meeting. These discussions encourage an open dialogue to identify and cultivate skills and opportunities and plan for career growth. We encourage and train our leaders to facilitate effective conversations and measure the effectiveness of these conversations by surveying our employees to monitor leadership effectiveness. In addition to training and development opportunities, all new employees are required to participate in trainings to introduce them to the EnerSys business, our strategy, culture and philosophies. We encourage all our employees to engage in mentoring, ongoing training, professional development and educational advancement programs. Through our established EnerSys Academy, we provide employees worldwide with resources to expand their skills and knowledge on a broad scope of relevant topics, to promote their growth and development.

Compensation and Benefits: To attract, retain and recognize talent, we aim to ensure merit-based compensation practices and strive to provide competitive compensation and benefit packages to our workforce. We provide employee wages that are consistent with employee positions, skill levels, experience, knowledge and geographic location. We align our executives’ and eligible employees’ annual bonus opportunity and long-term equity compensation with our stockholders’ interests by linking realizable pay with company financial performance. In addition, we perform annual pay equity studies to evaluate our global pay practices across the organization and routinely audit pay practices globally to ensure compliance with local, state, municipality, country and/or federal law.

Sustainability

At EnerSys, we understand that an effective business strategy must also be one that evaluates and addresses environmental, social governance risk factors as well as opportunities to leverage sustainable operations and ethical behavior as a means of driving business value. To that end, we continue to integrate the fundamental values of sustainabilityinto our everyday operations and future business strategies. Our Sustainability Team coordinates our environmental, social and governance efforts with respect to climate change management, product sustainability, operations, and supply chain management and corresponding sustainability-specific disclosures.

Sustainability, reliability and resilience are at the core of who we are and what we do at EnerSys every day. Our products help tackle some of our world’s most significant challenges, be it efficient and affordable distribution of goods, grid reliability, telecommunications, medical safety or addressing the impacts of climate change and decarbonization. Our batteries and energy storage solutions are part of building a resilient, low-carbon future.

Table of Contents

Sustainability at EnerSys is, however, about more than just the benefits and impacts of our products. Our commitment encompasses essential environmental, social and governance issues fundamental to how we manage our own operations. Optimizing our natural resource management, minimizing our environmental footprint and providing a safe and inclusive workplace for our employees are top priorities for EnerSys. Being an excellent neighbor and good corporate citizen in the communities where we work and live is extremely important as well. Our products facilitate positive environmental, social and economic impacts around the world. We believe that the power systems and energy management sector have a key role to play in finding innovative solutions to address global climate change. Our Climate Change policy underscores our goal to carry out all business activities in a sustainable manner. Our Environmental Policy and practices aim to protect, conserve, and sustain the world’s natural resources, as well as to protect our customers and the communities in which we live and operate. As one example of this, we offer a complete battery recycling program to assist our customers in preserving natural resources and comply with recycling and waste disposal regulations.

Relationships between EnerSys and our suppliers must be based on mutual respect and integrity. Our strategic sourcing, purchasing and quality teams strive to maintain the highest standards and principles of business ethics, courtesy and competence in dealings and transactions with suppliers. Our code of supplier conduct reflects our commitment to the values of honesty, integrity, respect, and responsibility. We expect our suppliers will share and embrace our values, as well as our commitment to regulatory compliance.

We have a sustainability steering committee, which includes members of senior management and maintain a dedicated team to further support the ongoing development of our sustainability program. Our Board of Directors oversees our programs related to matters of corporate responsibility and sustainability performance, including climate change, through the Nominating and Corporate Governance Committee. We publish an annual Sustainability Report, including environmental, social and governance data, as well as a Task Force on Climate Related Financial Disclosures report and submission to the CDP. We are members of United Nations Global Compact, Alliance to Save Energy, the U.S. Department of Energy’s Better Plants Program (through which we committed to reducing our energy intensity by 25% over the next 10 years (from a calendar year 2020 baseline)), and the United Nations CEO Water Mandate. These actions demonstrate the strength and commitment to sustainability throughout the organization worldwide.

ITEM 1A. RISK FACTORS

The following are certain risk factors that could materially and adversely affect our business, financial condition and our results of operations and could cause actual results to differ materially from our expectations and projections. Stockholders are cautioned that these and other factors, including those beyond our control, may affect future performance and cause actual results to differ from those which may, from time to time, be anticipated. The risks that are described below are not the only ones that we face. These risk factors should be considered in connection with the matters discussed herein under “Cautionary Note Regarding Forward-Looking Statements” and other information included and incorporated by reference in this Form 10-K as well as in other reports and materials that we file with the SEC. All forward-looking statements made by us or on our behalf are qualified by the risks described below. Although the risks are organized by headings and by category, many risks are interrelated. You should not interpret the disclosure of any risk factor to imply that the risk has not already materialized.

Business and Operating Risks

We operate in an extremely competitive industry and are subject to pricing pressures.

We compete with a number of major international manufacturers and distributors, as well as a large number of smaller, regional competitors. Due to excess capacity in some sectors of our industry and consolidation among industrial battery purchasers, we have been subjected to significant pricing pressures. We anticipate continued competitive pricing pressure as foreign producers are able to employ labor at significantly lower costs than producers in the U.S. and Western Europe, expand their export capacity and increase their marketing presence in our major Americas and European markets. Several of our competitors have strong technical, marketing, sales, manufacturing, distribution and other resources, as well as significant name recognition, established positions in the market and long-standing relationships with OEMs and other customers. In addition, certain of our competitors own lead smelting facilities which, during periods of lead cost increases or price volatility, may provide a competitive pricing advantage and reduce their exposure to volatile raw material costs. Our ability to maintain and improve our operating margins depends on our ability to control and reduce our costs in addition to our ability to maintain business relationships with customers. If we are unable to offset pricing pressures, our profitability and cash flows could be adversely affected. We cannot assure you that we will be able to continue to control our operating expenses, to raise or maintain our prices or increase our unit volume, in order to maintain or improve our operating results.

Reliance on third party relationships and derivative agreements could adversely affect our business.

We depend on third parties, including suppliers, distributors, lead toll operators, freight forwarders, insurance brokers, commodity brokers, major financial institutions and other third party service providers, for key aspects of our business, including the provision of derivative contracts to manage risks of commodity cost volatility, foreign currency exposures and interest rate volatility. Failure of these third parties to meet their contractual, regulatory and other obligations to us, or the development of factors that materially disrupt our relationships with these third parties, could expose us to the risks of business disruption, higher commodity and interest costs, unfavorable foreign currency rates and higher expenses, which could have a material adverse effect on our business.

We may experience issues with lithium-ion cells or other components manufactured at our proposed gigafactory, which may harm the production and profitability of our energy storage products.

Our plan to grow the volume and profitability of our energy storage products depends on significant lithium-ion battery cell production, including by our partner Verkor SAS at a proposed gigafactory in South Carolina.If we are unable to commence, or, when opened, otherwise do not maintain and grow, our respective operations, if we cannot execute our strategy, or if we are unable to do so cost-effectively or hire and retain highly-skilled personnel there, our ability to manufacture our products profitably would be limited, which may harm our business and operating results. Additionally, the start-up of operations after such project has been completed is also subject to risk. In addition, in order to complete the construction of the proposed gigafactory, we are relying upon, among other things, short-term and long-term incentive packages through South Carolina and Greenville County, federal funding and benefits under Section 45X of the Internal Revenue Code. Our ability to realize and procure these benefits is subject to a variety of market, operational, regulatory and labor-related factors. Any failure to complete these projects, or any delays or failure to achieve the anticipated results from the implementation of this project, could have a material adverse effect on our business, financial condition, results of operations and liquidity.

Our $199 million funding from the U.S. Department of Energy ("DOE") is subject to review and will be subject to negotiation of specific terms and contingent on our compliance with the requirements negotiated with the DOE.

Table of Contents

In January 2025, we entered into an agreement with the DOE's Office of Manufacturing and Energy Supply Chains for a $199 million award to support the construction of a new lithium-ion cell production facility in Greenville, South Carolina. Since that time, the issuance of certain executive orders, including the Unleashing American Energy Executive Order on January 20, 2025, has required an immediate pause in the disbursement of funds appropriated through the IRA pending an ongoing review. We are currently evaluating these executive orders and other related memoranda to determine what, if any, impact they might have on or our previously announced DOE funding. If the DOE proceeds with our funding as planned, such funding will additionally remain subject to certain compliance obligations and other terms and conditions.

Cost increases, supply disruptions or shortages of any of our battery components, such as electronic and mechanical parts, or the raw materials used in the production of such parts could adversely affect our business.

From time to time, we may experience increases in the cost or a sustained interruption in the supply or shortage of our components. For example, a global shortage and component supply disruptions of electronic and other battery components is currently being reported, and the full impact to us is not yet known. Additionally, the U.S. government has recently imposed, and is currently considering imposing, tariffs on certain trade partners. Other shortages and component supply disruptions could affect the supply of electronic components and raw materials (such as resins and other raw metal materials) that go into the production of our products. Cost increases or supply interruptions could materially and negatively impact our business, prospects, financial condition and operating results. The prices for our components fluctuate depending on market conditions and global demand and could adversely affect our business, prospects, financial condition and operating results. For instance, we are exposed to multiple risks relating to price fluctuations for battery cells. These risks include, but are not limited to:

•supply shortages caused by the inability or unwillingness of our suppliers and their competitors to build or operate component production facilities to supply the numbers of battery components required to support the rapid growth of the electric vehicle industry and other industries in which we operate as demand for such components increases;

•changes in import and export laws, including, but not limited to, sanctions, tariffs, and other economic measures;

•disruption in the supply of electronic circuits due to quality issues or insufficient raw materials;

•a decrease in the number of manufacturers of battery components; and

•an increase in the cost of raw materials.

We are dependent on the continued supply of battery components for our products. To date, we have a limited number of fully qualified suppliers, and have limited flexibility in changing suppliers, though we are actively engaged in activities to qualify additional suppliers. Any disruption in the supply of battery components could temporarily disrupt production of our products until a different supplier is fully qualified.

The cost of our battery products depends in part upon the prices and availability of raw materials such as lead, lithium, nickel, cobalt or other metals. Lead is our most significant raw material and is used along with significant amounts of plastics, steel, copper and other materials in our manufacturing processes. We estimate that raw material costs account for over half of our cost of goods sold. The prices for these materials fluctuate and their available supply may be unstable, depending on market conditions and global demand for these materials, including as a result of increased global production of electric vehicles and energy storage products. Additionally, our suppliers may not be willing or able to reliably meet our timelines or our cost and quality needs, which may require us to replace them with other sources. Furthermore, fluctuations or shortages in petroleum and other economic conditions may cause us to experience significant increases in freight charges and other transportation costs. Any reduced availability of these raw materials or substantial increases in their prices may increase the cost of our components and consequently, the cost of our products. There can be no assurance that we will be able to recoup increasing costs of our components by increasing prices, which in turn could damage our brand, business, prospects, financial condition and operating results.

Volatile raw material costs can significantly affect our operating results and make period-to-period comparisons difficult. To reduce the volatility of our costs, we periodically enter into hedging arrangements for a portion of our projected lead requirements. However, we cannot assure you that we will be able to either hedge the costs or secure the availability of our raw material requirements at a reasonable level or, even with respect to our agreements that adjust pricing to a market-based index for lead, pass on to our customers the increased costs of our raw materials without affecting demand or that limited availability of materials will not impact our production capabilities. Our inability to raise the price of our products in response to increases in prices of raw materials due to pricing pressure, contract terms or other factors or to maintain a proper supply of raw materials could have an adverse effect on our business, financial position and results of operations.

Tariffs, economic sanctions and other changes in U.S. trade policy have in the past and could in the future trigger retaliatory actions by affected countries, and certain foreign governments have instituted or are considering imposing retaliatory measures on certain U.S. goods. Our business, like many other corporations, would be impacted by changes to the trade policies of the United States and foreign countries (including governmental action related to tariffs, international trade agreements, or

Table of Contents

economic sanctions). Such changes have the potential to adversely impact the U.S. economy or certain sectors thereof, the global economy, and our industry, and as a result, could have a material adverse effect on our business, financial condition and results of operations.

We have experienced and may continue to experience, difficulties implementing our global enterprise resource planning system, which may adversely affect our business, financial condition and results of operations.

We are engaged in a multi-year implementation of a global enterprise resource planning system (“ERP”). The ERP is designed to standardize business processes to efficiently maintain our financial records and provide critical operational information to our management team. The ERP will continue to require significant investment of human and financial resources. In our prior efforts implementing the ERP, we experienced significant production and shipping delays, increased costs and other difficulties. Any significant disruption or deficiency in the design and implementation of the ERP could adversely affect our ability to process orders, ship products, send invoices and track payments, fulfill contractual obligations or otherwise operate our business. Even with our investment of significant resources into the ERP system, additional and significant implementation issues may arise. In addition, our efforts to centralize various business processes and functions within our organization in connection with our ERP implementation may disrupt our operations, divert management’s attention and negatively impact our business, financial condition and results of operations.

The failure to successfully implement efficiency and cost reduction initiatives, including restructuring activities, could materially adversely affect our business, financial position and results of operations, and we may not realize some or all of the anticipated benefits of those initiatives.

From time to time, we have implemented efficiency and cost reduction initiatives intended to improve our profitability and to respond to changes impacting our business and industry. These initiatives include relocating manufacturing to lower cost regions, consolidating and closing facilities, working with our material suppliers to lower costs, product design and manufacturing improvements, personnel reductions and voluntary retirement programs, and strategically planning capital expenditures and development activities. In the past we have recorded net restructuring charges to cover costs associated with our cost reduction initiatives involving restructuring. These costs have been primarily composed of employee separation costs, including severance payments, and asset impairments or losses from disposal. We also undertake restructuring activities and programs to improve our cost structure in connection with our business acquisitions, which can result in significant charges, including charges for severance payments to terminated employees and asset impairment charges.

We cannot assure you that our efficiency and cost reduction initiatives will be successfully or timely implemented, or that they will materially and positively impact our profitability. Because our initiatives involve changes to many aspects of our business, the associated cost reductions could adversely impact productivity and sales to an extent we have not anticipated. In addition, our ability to complete our efficiency and cost-savings initiatives and achieve the anticipated benefits within the expected time frame is subject to estimates and assumptions and may vary materially from our expectations, including as a result of factors that are beyond our control. Furthermore, our efforts to improve the efficiencies of our business operations and improve growth may not be successful. Even if we fully execute and implement these activities and they generate the anticipated cost savings, there may be other unforeseeable and unintended consequences that could materially adversely impact our profitability and business, including unintended employee attrition or harm to our competitive position. To the extent that we do not achieve the profitability enhancement or other benefits of our efficiency and cost reduction initiatives that we anticipate, our business, financial position and results of operations may be materially adversely affected.

Our failure to introduce new products and product enhancements coupled with broad market acceptance of new technologies introduced by our competitors could adversely affect our business.

Many new energy storage technologies have been introduced over the past several years. For certain important and growing markets, including markets served by our Motive Power and Energy Storage business segments, lithium-based battery technologies have a growing market share. Our ability to achieve significant and sustained penetration of key developing markets, including markets served by our Motive Power and Energy Storage business segments, will depend upon our success in developing or acquiring these and other technologies and related raw materials and components, either independently, through joint ventures or through acquisitions. If we fail to develop or acquire, and manufacture and sell, products that satisfy our customers’ demands, or we fail to respond effectively to new product announcements by our competitors by quickly introducing competitive products, then market acceptance of our products could be reduced and our business could be adversely affected. We cannot assure you that our portfolio of primarily lead-acid products will remain competitive with products based on new technologies.

If we are not able to adequately protect our proprietary intellectual property and technology, we may lose any technological advantages and our business, financial position and results of operations may be materially adversely affected.

Table of Contents

We rely on a combination of copyright, trademark, patent and trade secret laws, non-disclosure agreements and other confidentiality procedures and contractual provisions to establish, protect and maintain our proprietary intellectual property and technology and other confidential information. Certain of these technologies, especially thin plate pure lead (“TPPL”) technology, are important to our business and are not protected by patents. Despite our efforts to protect our proprietary intellectual property and technology and other confidential information, unauthorized parties may attempt to copy or otherwise obtain and use our intellectual property and proprietary technologies. Successful cybersecurity attacks, data breaches, unauthorized exfiltration, unapproved use of machine learning or artificial intelligence tools, or other security incidents could result in the loss of intellectual property and key technological advantages. If we are unable to protect our intellectual property and technology, we may lose any technological advantage we currently enjoy and may be required to take an impairment charge with respect to the carrying value of such intellectual property or goodwill established in connection with the acquisition thereof.In either case, our business, financial position and results of operations may be materially adversely affected.

Relocation of our customers’ operations could adversely affect our business, financial condition and results of operations.

The trend by a number of our North American and Western European customers to move manufacturing operations and expand their businesses in faster growing and lower labor-cost markets may have an adverse impact on our business, financial condition and results of operations. These territories may be farther from our manufacturing plants, and there is a risk that these customers will source their energy storage products from competitors located in those territories and will cease or reduce the purchase of products from us.We cannot assure you that we will be able to compete effectively with our competitors located in those territories, whether by establishing or expanding our manufacturing operations in those territories or acquiring existing manufacturers in those territories.

Quality problems with our products could harm our reputation and erode our competitive position.

The success of our business depends upon the quality of our products and our relationships with customers. In the event that our products fail to meet our customers’ standards, our reputation could be harmed. This could result in the loss of customers, a decrease in revenue and a loss of market share. We cannot assure you that our customers will not experience quality problems with our products. Warranty, recall or product liability claims could also materially adversely affect our business and reputation. In our business, we are exposed to warranty and product liability claims. In addition, we may be required to participate in the recall of a product.If we fail to meet customer specifications for their products, we may be subject to product quality costs and claims, as well as adverse reputational impacts.A successful warranty or product liability claim against us, or a requirement that we participate in a product recall, could have a material adverse effect on our business, financial condition and results of operations.

We offer our products under a variety of brand names, the protection of which is important to our reputation for quality in the consumer marketplace.

We rely upon a combination of trademark, licensing and contractual covenants to establish and protect the brand names of our products. We have registered many of our trademarks in the U.S. Patent and Trademark Office and in other countries. In many market segments, our reputation is closely related to our brand names. Monitoring unauthorized use of our brand names is difficult, and we cannot assure you that the steps we have taken will prevent the unauthorized use of our brand names, particularly in foreign countries where the laws may not protect our proprietary rights as fully as in the U.S. We cannot assure you that our brand names will not be misappropriated or utilized without our consent.In the event of any such actions, our reputation and our business, financial condition and results of operations may be materially adversely affected.

Our growth strategy depends on our ability to continue to expand our market presence through acquisitions, and our business could be materially adversely affected if we are unable to identify suitable acquisition candidates, complete any proposed acquisitions or successfully integrate the businesses we acquire.

As part of our growth strategy, we depend on acquisitions of other product lines, technologies or facilities that complement or expand our existing business. Acquisitions involve numerous risks, including:

•inability to overcome significant competition for acquisition targets in the stored energy industry;

•inability to identify suitable acquisition candidates or negotiate attractive terms;

•difficulty obtaining the financing necessary to complete transactions we pursue, as our credit facilities restrict the amount of additional indebtedness that we may incur to finance acquisitions and place other restrictions on our ability to make acquisitions (and exceeding any of these restrictions would require the consent of our lenders);

Table of Contents

•failure to identify all material issues through a customary due diligence investigation, and that material issues will arise later;

•difficulties in the assimilation of the operations, systems, controls, technologies, personnel, services and products of the acquired business;

•potential loss of key employees, customers, suppliers and distributors of the acquired business;

•diversion of our management’s attention from other business concerns;

•incurrence of additional debt or adverse tax and accounting consequences in connection with any acquisitions;

•failure to successfully integrate the acquired businesses in a timely manner, or at all;

•incurrence of significant unanticipated expenses associated with integration activities; and

•anticipated benefits of an acquisition not being realized fully or at all, or taking longer to realize than we expect.

The materialization of any of the foregoing risks could impair our ability to successfully execute our acquisition growth strategy, which could have a material adverse effect on our business.

Any acquisitions that involve the issuance of our equity securities may dilute our stockholder ownership interests, reduce the market price of our stock, or both, and as a result our business, financial condition and results of operations could be adversely affected.

Future acquisitions may involve the issuance of our equity securities as payment, in part or in full, for the businesses or assets acquired. Any future issuances of equity securities may dilute our stockholders’ proportionate ownership interests in EnerSys. In addition, the benefits derived by us from an acquisition might not outweigh or exceed the dilutive effect of any issuance of equity securities in connection with the acquisition.We cannot predict or estimate the amount or timing of any future acquisitions or related issuances of equity securities.Our stockholders bear the risk of any such future offerings reducing the market price of our stock and diluting their proportionate ownership interests in EnerSys.

If our electronic data is compromised, our business could be materially adversely affected.

We and our business partners maintain significant amounts of data electronically in locations around the world. This data relates to all aspects of our business, including current products and services and future products and services under development.This data also contains certain customer, supplier, partner and employee information. We maintain systems and processes designed to protect this data.However, notwithstanding such protective measures, there is a risk of intrusion, cyberattacks, tampering, theft, misplaced or lost data, programming or human errors that could compromise the integrity and privacy of this data, improper use of our systems, software solutions or networks, power outages, hardware failures, computer viruses, failure of critical computer systems, unauthorized access, use, disclosure, modification or destruction of information, defective products, production downtimes and operational disruptions, which in turn could adversely affect our business, financial condition and results of operations.

We provide confidential and proprietary information to our third-party business partners in certain cases where doing so is necessary to conduct our business. While we obtain assurances from those parties that they have systems and processes in place to protect such data and, where applicable, that they will take steps to assure the protections of such data by third parties, those partners may be subject to the same risks as we are.

In particular, we and our third-party business partners experience cybersecurity incidents of varying degrees from time-to-time, including ransomware and phishing attacks as well as distributed denial of service attacks and the theft of data.Cyber threats are constantly evolving, are becoming more sophisticated and are being made by groups and individuals with a wide range of expertise and motives, and this increases the difficulty of detecting and successfully defending against them.

Any compromise of the confidential data of our customers, suppliers, partners, employees or ourselves, or failure to prevent or mitigate the loss of or damage to this data through breach of our information technology systems or other means could substantially disrupt our operations, harm our customers, employees and other business partners, damage our reputation, violate applicable laws and regulations, subject us to potentially significant costs and liabilities and result in a loss of business that could be material.

Our software and related services are highly technical and may contain undetected software bugs, errors or other vulnerabilities, which could manifest in ways that could adversely affect our reputation and our business.

Table of Contents

The software and related services that we offer are highly technical and complex. Our services or any other products that we may introduce in the future may contain undetected software bugs, hardware errors and other vulnerabilities. These vulnerabilities can manifest in any number of ways in our products, including through diminished performance, security vulnerabilities, malfunctions, or even permanently disabled products. We have a practice of regularly updating our products, and some errors in our products may be discovered only after a product has been used.In some cases, any vulnerabilities may only be detected under certain circumstances or after extended use. Any errors, bugs or other vulnerabilities discovered in our code or backend after release could damage our reputation, alienate users, allow third parties to manipulate or exploit our software, lower revenue and expose us to claims for damages, any of which could adversely affect our business. Additionally, errors, bugs or other vulnerabilities may, either directly or if exploited by third parties, affect our ability to make accurate royalty payments.We also could face claims for product liability, tort or breach of warranty as a result. Defending a lawsuit, regardless of its merit, is costly and may divert management’s attention and adversely affect our reputation and our business.In addition, if our liability insurance coverage proves inadequate or future coverage is unavailable on acceptable terms or at all, our business could be seriously harmed.

If we cannot keep pace with rapid developments in technology, the use of our products and services and, consequently, our revenues could decline.

Our business continues to demand the use of sophisticated systems and technology. These systems and technologies must be refined, updated and replaced with more advanced systems on a regular basis in order for us to meet our customers’ demands and expectations.We expect that new technologies applicable to our business will continue to emerge and may be superior to, or render obsolete, the technologies we currently use in our products and services.We cannot predict the effects of technological changes on our business, which technological developments or innovations will become widely adopted, and how those technologies may be regulated.Developing and incorporating new or updated systems and technologies into new and existing products and services may require significant investment, take considerable time and may not ultimately be successful.If we are unable to do so on a timely basis or within reasonable cost parameters, or if we are unable to appropriately and timely train our employees to operate any of these new systems or technologies, our business could be adversely affected. We also may not achieve the benefits that we anticipate from any new system or technology and a failure to do so could result in higher than anticipated costs and adversely affect our results of operations.

Work stoppages or similar difficulties could significantly disrupt our operations, reduce our revenues and materially adversely affect our business.

A work stoppage at one or more of our facilities, whether caused by fire, flooding, epidemics, pandemics, military hostilities, government-imposed shutdowns, severe weather, including that caused by climate change, other natural disaster or otherwise, could have a material adverse effect on our business, financial condition and results of operations. In addition, some of our employees are represented by labor unions or works councils under collective bargaining agreements with varying durations and terms. Although we believe that our relations with our employees are strong, if our unionized workers were to engage in a strike, work stoppage or other slowdown in the future, we could experience a significant disruption of our operations. No assurances can be made that we will not experience work stoppages due to government directives, employee health concerns, and other types of conflicts with labor unions, works councils, and other similar groups in the future.

A work stoppage at one or more of our suppliers could also materially and adversely affect our business if an alternative source of supply is not readily available. In addition, if one or more of our customers were to experience a work stoppage, that customer could cease or limit purchases of our products, which could have a material adverse effect on our business, financial condition and results of operations. In addition, the credit and default risk or bankruptcy of customers or suppliers as a result of work stoppages could likewise materially and adversely affect our business, financial condition and results of operations.

Global Operations Risks

Our results of operations may be negatively impacted by public health epidemics or outbreaks.

Public health epidemics or outbreaks could adversely impact our global operations. For example, the COVID-19 pandemic caused disruption to the global economy, including economic slowdowns and supply chain disruptions that adversely affected our business, financial position and results of operations. In response to public health epidemics or outbreaks, countries imposed prolonged quarantines and travel restrictions, which may significantly impact the ability of our employees to get to their places of work to produce products, may make it such that we are unable to obtain sufficient components or raw materials and component parts on a timely basis or at a cost-effective price or may significantly hamper our products from moving through the supply chain.

Table of Contents

We rely on our production facilities, as well as third-party suppliers and manufacturers, in the United States, Australia, Canada, France, Germany, Italy, the People’s Republic of China (“PRC”), the United Kingdom and other countries that were significantly impacted by COVID-19. Shutdowns of certain businesses in many of these countries resulted in disruptions or delays to our supply chain or reduction in demand for certain products. Although disruptions may continue to occur and the future impact of the outbreak is uncertain, the impacts of the public health epidemics or outbreaks (or events similar to COVID-19 in the future) cannot be reliably quantified at this time.

The rapid spread of a contagious illness such as COVID-19, poses the risk that our employees, contractors, suppliers and customers may be prevented from conducting business, which may have a material adverse effect on our business, financial position and results of operations.

The uncertainty in global economic conditions or geographic regions in which our customers operate could adversely affect our business, financial position and operating results.

Our operating results are directly affected by the general global economic conditions of the industries in which our major customer groups operate. Our products are heavily dependent on the end markets that we serve and our operating results will vary by location, depending on the economic environment in these markets. Sales of our motive power products, for example, depend significantly on demand for new electric industrial forklift trucks, which in turn depends on end-user demand for additional motive capacity in their distribution and manufacturing facilities. The uncertainty in global economic conditions varies by geographic location and can result in substantial volatility in global credit markets, particularly in the United States, where we service the vast majority of our debt. Moreover, Federal Reserve Bank of the United States policy, including with respect to interest rates and its quantitative easing policy, may also result in market volatility or a return to unfavorable economic conditions. These conditions affect our business by reducing prices that our customers may be able or willing to pay for our products or by reducing the demand for our products, which could in turn negatively impact our sales and earnings generation and result in a material adverse effect on our business, cash flow, results of operations and financial position.

Government reviews, inquiries, investigations and actions could harm our business or reputation.

As we operate in various locations around the world, our operations in certain countries are subject to significant governmental scrutiny and may be adversely impacted by the results of such scrutiny. The regulatory environment with regard to our business is evolving, and officials often exercise broad discretion in deciding how to interpret and apply applicable regulations. From time to time, we receive formal and informal inquiries from various government regulatory authorities, as well as self-regulatory organizations, about our business and compliance with local laws, regulations or standards.

Any determination that our operations or activities, or the activities of our employees, are not in compliance with existing laws, regulations or standards could result in the imposition of substantial fines, interruptions of business, loss of supplier, vendor, customer or other third-party relationships, termination of necessary licenses and permits, or similar results, all of which could potentially harm our business and reputation. Even if an inquiry does not result in these types of determinations, regulatory authorities could cause us to incur substantial costs or require us to change our business practices in a manner materially adverse to our business, and it potentially could create negative publicity which could harm our business and reputation.

Our international operations may be adversely affected by actions taken by foreign governments or other forces or events over which we may have no control.

We currently have significant manufacturing and distribution facilities outside of the United States, in Argentina, Australia, Belgium, Brazil, Canada, the Czech Republic, France, Germany, India, Italy, Malaysia, Mexico, the PRC, Poland, Spain, Switzerland and the United Kingdom. Our global operations are dependent upon products manufactured, purchased and sold in the U.S. and internationally, including in countries with political and economic instability or uncertainty. This includes, for example, the uncertainty related to the United Kingdom’s withdrawal from the European Union (commonly known as “Brexit”) the current conflict between Russia and Ukraine, ongoing terrorist activity,the conflict with Iran, the adoption and expansion of trade restrictions, including the occurrence or escalation of a “trade war,” or other governmental action related to tariffs or trade agreements or policies among the governments of the United States, the PRC and other countries and other global events. The global credit and financial markets have recently experienced extreme volatility and disruptions, including severely diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, increases in unemployment rates and uncertainty about economic stability. Sanctions imposed by the United States and other countries in response to such conflicts, including the one in Ukraine, may also adversely impact the financial markets and the global economy, and any economic countermeasures by affected countries and others could exacerbate market and economic instability. There can be no assurance that further deterioration in credit and financial markets and confidence in economic conditions will not occur. Recent effects of the conflict between Russia and Ukraine includes writing off $4 million in net assets located in Russia during fiscal 2022. Furthermore, Brexit could cause disruptions to, and create uncertainty surrounding our business, including affecting our relationships with our existing and future customers, suppliers and associates, which could have an adverse effect on our business, financial results and operations. Effects of Brexit include changes in customs regulations, shortages of truck drivers in

Table of Contents

the U.K., and administrative burdens placed on transportation companies have led to challenges and delays in moving inventory across U.K. or EU borders, and higher importation, freight and distribution costs. If such trends continue, we may experience further cost increases.

Some countries have greater political and economic volatility and greater vulnerability to infrastructure and labor disruptions than others. Our business could be negatively impacted by adverse fluctuations in freight costs, limitations on shipping and receiving capacity, and other disruptions in the transportation and shipping infrastructure at important geographic points of exit and entry for our products. Operating in different regions and countries exposes us to a number of risks, including:

•multiple and potentially conflicting laws, regulations and policies that are subject to change;

•changes in international treaties or trade unions, which may make our products or our customers' products more costly to export or import;

•imposition of currency restrictions, restrictions on repatriation of earnings or other restraints, imposition of burdensome import duties, tariffs or quotas, which may make our products more costly to export or import;

•changes in trade agreements;

•disadvantages of competing against companies from countries that are not subject to U.S. laws and regulations, including the FCPA;

•compliance with data protection regulations;

•imposition of new or additional trade and economic sanctions laws imposed by the U.S. or foreign governments;

•war or terrorist acts; and

•political and economic instability or civil unrest that may severely disrupt economic activity in affected countries.

The occurrence of one or more of these events may adversely affect our business, financial condition and results of operations.

We are exposed to exchange rate and inflation risks, and our net earnings and financial condition may suffer due to currency translations.

We invoice our foreign sales and service transactions in local and foreign currencies and translate net sales using actual exchange rates during the period. We translate our non-U.S. assets and liabilities into U.S. dollars using current exchange rates as of the balance sheet dates. Approximately 40% of net sales were generated outside of the United States in fiscal 2026. Because a significant portion of our revenues and expenses are denominated in foreign currencies, changes in exchange rates between the U.S. dollar and foreign currencies, including the effects of inflation, primarily the euro, British pound, Polish zloty, Chinese renminbi, Mexican peso and Swiss franc, may adversely affect our revenue, cost of goods sold and operating margins. For example, foreign currency depreciation against the U.S. dollar will reduce the value of our foreign revenues and operating earnings as well as reduce our net investment in foreign subsidiaries. In addition, we have balance sheet foreign currency positions that benefit from a stronger U.S. dollar and weak euro and may impact other income expense and equity on the balance sheet.

Most of the risk of fluctuating foreign currencies is in our European operations, which comprised approximately one-fifth of our net sales during the last three fiscal years. The euro is the dominant currency in our EMEA operations. In the event that one or more European countries were to replace the euro with another currency, our sales into such countries, or into Europe generally, would likely be adversely affected until stable exchange rates are established.

If foreign currencies depreciate against the U.S. dollar, it would make it more expensive for our non-U.S. subsidiaries to purchase certain of our raw material commodities that are priced globally in U.S. dollars, while the related revenue will decrease when translated to U.S. dollars. Significant movements in foreign exchange rates can have a material impact on our results of operations and financial condition. We periodically engage in hedging of our foreign currency exposures, but cannot assure you that we can successfully hedge all of our foreign currency exposures or do so at a reasonable cost.

We quantify and monitor our global foreign currency exposures. Our largest foreign currency exposure is from the purchase and conversion of U.S. dollar-based lead costs into local currencies in Europe. Additionally, we have currency exposures from intercompany financing and intercompany and third party trade transactions. On a selective basis, we enter into foreign currency forward contracts and purchase option contracts to reduce the impact from the volatility of currency movements; however, we cannot be certain that foreign currency fluctuations will not impact our operations in the future.

If we are unable to effectively hedge against currency fluctuations, our operating costs and revenues in our non-U.S. operations may be adversely affected. This, in turn, would have an adverse effect on our business, financial position and results of operations.

Financial and Accounting Risks

The Inflation Reduction Act of 2022 ("IRA") contains production tax credits for certain battery cells and battery modules. The Company's ability to benefit from Section 45X production tax credits is not guaranteed and is dependent upon the federal government's ongoing implementation, guidance, regulations, and/or rulemakings that have been the subject of substantial public interest and debate.

In August 2022, President Biden signed the IRA into law. The IRA provides for substantial tax credits and incentives for the development of critical minerals, renewable energy, clean fuels, electric vehicles, and supporting infrastructure, among other provisions. Section 45X of the Internal Revenue Code ("IRC") contains a production tax credit equal to 10% of certain eligible production costs, including, without limitation, labor, energy, depreciation and amortization and overhead expenses as well as credits for production of qualifying battery cells and modules. Effective October 24, 2024, the U.S. Department of the Treasury and the Internal Revenue Service released final rules to provide guidance on the production tax credit requirements under IRC Section 45X (the "Final Regulations"). The Final Regulations provide guidance on rules that taxpayers must satisfy to qualify for the Section 45X tax credit.

While Section 45X of the IRC provides for substantial tax benefits for us, there is some uncertainty as to how these provisions will be interpreted and implemented. Furthermore, future legislative enactments or administrative actions could limit, amend, repeal, or terminate IRA policies or other incentives to which currently benefit. Any reduction, elimination, or discriminatory application or expiration of Section 45X of the IRC may materially adversely affect our future operating results and operations.

We may not be able to maintain adequate credit facilities, which could materially adversely affect our business, financial condition and results of operations.

Our ability to continue our ongoing business operations and fund future growth depends on our ability to maintain adequate credit facilities and to comply with the financial and other covenants in such credit facilities or to secure alternative sources of financing. However, such credit facilities or alternate financing may not be available or, if available, may not be on terms favorable to us. If we do not have adequate access to credit, we may be unable to refinance our existing borrowings and credit facilities when they mature and fund future acquisitions, which may reduce our flexibility in responding to changing industry conditions and materially adversely affect our business, financial condition and results of operations.

Our indebtedness could adversely affect our business, financial condition and results of operations and restrict us in ways that limit our flexibility in operating our business.

As of March 31, 2026, we had $1,120 million of total consolidated debt (including finance leases). This level of debt could:

•increase our vulnerability to adverse general economic and industry conditions, including interest rate fluctuations, because a portion of our borrowings bear, and will continue to bear, interest at floating rates;

•require us to dedicate a substantial portion of our cash flow from operations to debt service payments, which would reduce the availability of our cash to fund working capital, capital expenditures or other general corporate purposes, including acquisitions;

•limit our flexibility in planning for, or reacting to, changes in our business and industry;

•restrict our ability to introduce new products or technologies or exploit business opportunities;

•place us at a disadvantage compared with competitors that have proportionately less debt;

•limit our ability to borrow additional funds in the future, if we need them, due to financial and restrictive covenants in our debt agreements;

•limit our operating and financial flexibility due to financial and restrictive covenants in our debt agreements; and

•have a material adverse effect on us if we fail to comply with the financial and restrictive covenants in our debt agreements.

In addition, our ability to make scheduled payments on or to refinance our debt obligations depends on our financial condition and operating performance, which is subject to prevailing economic and competitive conditions and to financial, business, legislative, regulatory and other factors, some of which are beyond our control. Any failure to make scheduled payments could adversely affect our business, financial condition and results of operations.

We may have exposure to greater than anticipated tax liabilities, which could adversely impact our business, financial position and results of operations.

Our income tax obligations are based in part on our corporate operating structure and intercompany arrangements, including the manner in which we operate our business, develop, value, manage, protect, and use our intellectual property and the valuations of our intercompany transactions. We may also be subject to additional indirect or non-income based taxes. The tax laws applicable to our business, including the laws of the United States and other jurisdictions, are subject to interpretation, and certain jurisdictions are aggressively interpreting their laws in new ways in an effort to raise additional tax revenue from multi-national companies like us. The taxing authorities of the jurisdictions in which we operate may challenge our tax positions and

Table of Contents

methodologies for valuing developed technology or intercompany arrangements, which could increase our worldwide effective tax rate and adversely impact our business, financial position and results of operations. Although we believe that our provision for income taxes is reasonable, the ultimate tax outcome may differ from the amounts recorded in our financial statements and may materially affect our financial results in the period or periods for which such determination is made. In addition, our future income tax rates could be adversely affected by earnings being lower than anticipated in jurisdictions that have lower statutory tax rates and higher than anticipated in jurisdictions that have higher statutory tax rates, by changes in the valuation of our deferred tax assets and liabilities, or by changes in tax laws, regulations, or accounting principles.

Changes in tax laws or tax rulings could materially affect our business, financial position and results of operations.

The income and non-income tax regimes to which we are subject or under which we operate are unsettled and may be subject to significant change. Changes in tax laws or tax rulings, or changes in interpretations of existing laws, could materially affect our business, financial position and results of operations. In addition, many countries in Europe, as well as a number of other countries and organizations, have recently proposed or recommended changes to existing tax laws or have enacted new laws that could significantly increase our tax obligations in many countries where we do business or require us to change the manner in which we operate our business. For example:

•On August 16, 2022, the U.S. Congress passed the Inflation Reduction Act of 2022 (the “IRA”), which, among other provisions, creates a new corporate alternative minimum tax (“CAMT”) of at least 15% for certain large corporations that have at least an average of $1 billion in adjusted financial statement income over a consecutive three-year period effective after December 31, 2022. The IRA also includes a 1% excise tax on certain stock repurchases beginning in 2023. We do not expect to meet the CAMT threshold in the near term. However, we expect a material portion of our U.S. produced batteries and battery cells, including our proprietary TPPL batteries, will qualify for production tax credits under Section 45X of the IRA. For more information, see “The Inflation Reduction Act of 2022 ("IRA") contains production tax credits for certain battery cells and battery modules. The Company's ability to benefit from Section 45X production tax credits is not guaranteed and is dependent upon the federal government's ongoing implementation, guidance, regulations, and/or rulemakings that have been the subject of substantial public interest and debate.” above.

•In 2021, the Organization for Economic Cooperation Development (the “OECD”), through an association of more than 140 countries, announced a consensus around a two-pillar approach to address tax challenges presented by digital commerce. “Pillar 1” focuses on nexus and profit allocation, and “Pillar 2” focuses on a minimum global effective tax rate of 15%. On December 15, 2022, the European Union adopted the Pillar Two directive and EU member states were expected to implement Pillar Two into domestic law by December 31, 2023.

•On January 5, 2026, the OECD issued the Side-by-Side package (the “SbS Package”), which provides administrative guidance that modifies the application of the Pillar Two rules. The SbS Package includes simplifications and additional safe harbors intended to facilitate coordination between domestic and international tax regimes and the Pillar Two framework. If adopted by relevant jurisdictions, certain provisions of the SbS Package could result in U.S.-parented groups being exempt from the application of two of the three Pillar Two top-up taxes.

We closely monitor these developments in the countries where we operate. Changes to the statutory tax rate may occur at any time, and any related expense or benefit recorded may be material to the fiscal quarter and year in which the law change is enacted. The European Commission has conducted investigations in multiple countries focusing on whether local country tax rulings or tax legislation provides preferential tax treatment that violates European Union state aid rules and concluded that certain countries, have provided illegal state aid in certain cases. These investigations may result in changes to the tax treatment of our foreign operations. Due to the large and expanding scale of our international business activities, many of these types of changes to the taxation of our activities could increase our worldwide effective tax rate and adversely affect our business, financial position and results of operations. Such changes may also apply retroactively to our historical operations and result in taxes greater than the amounts estimated and recorded in our financial statements.

In connection with the OECD’s Base Erosion and Profit Shifting (BEPS) project, companies are required to disclose more information to tax authorities on operations around the world, which may lead to greater audit scrutiny of profits earned in other countries. We regularly assess the likely outcomes of our tax audits and disputes to determine the appropriateness of our tax reserves. However, any tax authority could take a position on tax treatment that is contrary to our expectations, which could result in tax liabilities in excess of reserves.

Legal and Regulatory Risks

Our operations expose us to environmental, health and safety and other legal compliance risks, and any noncompliance could adversely affect our business.

Table of Contents

As a global business, we are subject to extensive environmental liability on our operations due to current environmental laws and regulations in the jurisdictions we operate.

If convicted or found liable for violation of a law or regulation, we could be subject to significant fines, penalties, repayments or other damages. Laws and regulations may also change from time to time, as may related interpretations and other guidance, resulting in potentially higher expenses and payments and affect how we conduct our operations and structure our investments.

We process, store, dispose of and otherwise use large amounts of hazardous materials, especially lead and acid in the manufacturing of our products. As a result, we are subject to extensive and changing environmental, health and safety laws and regulations governing, among other things: the generation, handling, storage, use, transportation and disposal of hazardous materials; remediation of polluted ground or water; emissions or discharges of hazardous materials into the ground, air or water; and the health and safety of our employees. Failure to comply with these laws or regulations, or to obtain or comply with required environmental permits, could result in fines, criminal charges or other sanctions by regulators. From time to time we have had instances of alleged or actual noncompliance that have resulted in the imposition of fines, penalties and required corrective actions. Our ongoing compliance with environmental, health and safety laws, regulations and permits could require us to incur significant expenses, limit our ability to modify or expand our facilities or continue production and require us to install additional pollution control equipment and make other capital improvements. In addition, private parties, including current or former employees, could bring personal injury or other claims against us due to the presence of, or exposure to, hazardous substances used, stored or disposed of by us or contained in our products.

Certain environmental laws assess liability on owners or operators of real property for the cost of investigation, removal or remediation of hazardous substances at their current or former properties. These laws may also assess costs to repair damage to natural resources. We may be responsible for remediating damage to our properties caused by former owners. Soil and groundwater contamination has occurred at some of our current and former properties and may occur or be discovered at other properties in the future. In accordance with regulatory permits, we are currently investigating and monitoring soil and groundwater contamination at several of our properties, in most cases as required by regulatory permitting processes. We may be required to conduct these operations at other properties in the future. In addition, we have been, and in the future, may be liable to contribute to the cleanup of locations owned or operated by other persons to which we or our predecessor companies have sent waste for disposal, pursuant to federal and other environmental laws. Under these laws, the owner or operator of contaminated properties and companies that generated, disposed of or arranged for the disposal of wastes sent to a contaminated disposal facility can be held jointly and severally liable for the investigation and cleanup of such properties, regardless of fault. Additionally, our products may become subject to fees and taxes in order to fund cleanup of such properties, including those operated or used by other lead-battery industry participants.

Changes in environmental and climate-related laws and regulations could lead to new or additional investment in production designs and could increase environmental compliance expenditures. For example, the European Union has enacted greenhouse gas emissions legislation, and continues to expand the scope of such legislation. The United States Environmental Protection Agency has promulgated regulations applicable to projects involving greenhouse gas emissions above a certain threshold, and the United States and certain states within the United States have enacted, or are considering, limitations on greenhouse gas emissions.

Changes in climate change concerns, or in the regulation of such concerns, including greenhouse gas emissions, could subject us to additional costs and restrictions, including increased energy and raw materials costs. Additionally, we cannot assure you that we have been or at all times will be in compliance with environmental laws and regulations or that we will not be required to expend significant funds to comply with, or discharge liabilities arising under, environmental laws, regulations and permits, or that we will not be exposed to material environmental, health or safety litigation.

We are subject to a wide variety of domestic and foreign laws and regulations that could adversely affect our business, financial condition and results of operations.

We are subject to a wide variety of domestic and foreign laws and regulations, and legal compliance risks, including securities laws, tax laws, data privacy laws, employment and pension-related laws, competition laws, U.S. and foreign export and trade laws, government procurement regulations, and laws governing improper business practices. We are affected by both new laws and regulations, and changes to existing laws and regulations which may continue to evolve through interpretations by courts and regulators. Furthermore, the laws and regulations to which we are subject may differ from jurisdiction to jurisdiction, further increasing the cost of compliance and the risk of noncompliance.

In particular, the U.S. Foreign Corrupt Practices Act (“FCPA”) and similar worldwide anti-bribery laws in non-U.S. jurisdictions generally prohibit companies and their intermediaries from making improper payments to non-U.S. officials for the purpose of obtaining or retaining business. The FCPA applies to companies, individual directors, officers, employees and agents. Under the FCPA, U.S. companies may be held liable for actions taken by strategic or local partners or representatives. The FCPA also imposes accounting standards and requirements on publicly traded U.S. corporations and their foreign affiliates,

Table of Contents

which are intended to prevent companies and their intermediaries from making improper payments to non-U.S. government officials for the purpose of obtaining or retaining business. Certain of our customer relationships outside of the U.S. are with governmental entities and are therefore subject to such anti-bribery laws. Our policies mandate compliance with these anti-bribery laws. Despite meaningful measures that we undertake to facilitate lawful conduct, which include training and internal control policies, these measures may not always prevent reckless or criminal acts by our employees or agents. As a result, we could be subject to criminal and civil penalties, disgorgement, further changes or enhancements to our procedures, policies and controls, personnel changes or other remedial actions. Violations of these laws, or allegations of such violations, could disrupt our operations, involve significant management distraction and result in a material adverse effect on our competitive position, results of operations, cash flows or financial condition.

Complying or failing to comply with conflict minerals regulations could materially and adversely affect our supply chain, our relationships with customers and suppliers and our financial results.

We are currently subject to conflict mineral disclosure regulations in the U.S. and may be affected by new regulations concerning conflict and similar minerals adopted by other jurisdictions where we operate. U.S. legislation included disclosure requirements regarding the use of conflict minerals mined from the Democratic Republic of Congo and adjoining countries and procedures regarding a manufacturer’s efforts to prevent the sourcing of such conflict minerals. In addition, the European Union adopted an EU-wide conflict minerals rule under which most EU importers of tin, tungsten, tantalum, gold and their ores will have to conduct due diligence to ensure the minerals do not originate from conflict zones and do not fund armed conflicts. We have and will continue to incur added costs to comply with the disclosure requirements, including costs related to determining the source of such minerals used in our products. We may not be able to ascertain the origins of such minerals that we use and may not be able to satisfy requests from customers to certify that our products are free of conflict minerals. These requirements also could constrain the pool of suppliers from which we source such minerals. We may be unable to obtain conflict-free minerals at competitive prices which will increase costs and may materially and adversely affect our manufacturing operations and profitability.

Our failure to comply with data privacy regulations could adversely affect our business.

There are new and emerging data privacy laws, as well as frequent updates and changes to existing data privacy laws, in most jurisdictions in which we operate. Given the complexity of these laws and the requirements they place on businesses regarding the collection, storage, handling, use, disclosure, transfer and security of personal data, it is important for us to understand their impact and respond accordingly. Failure to comply with data privacy laws can result in substantial fines or penalties, legal liability or reputational damage.

In Europe, the General Data Protection Regulation (the “GDPR”), which came into effect in 2018, places stringent requirements on companies when handling personal data and there continues to be a growing trend of other countries adopting similar laws, including Canada. Additionally, there continues to be significant uncertainty with respect to the California Consumer Privacy Act of 2018 (the “CCPA”), which went into effect on January 1, 2020, and imposes additional obligations on companies regarding the handling of personal information and provides certain individual privacy rights to persons whose information is collected. Both the GDPR and the CCPA are continuously evolving and developing and may be interpreted and applied differently from jurisdiction to jurisdiction and may create inconsistent or conflicting requirements. For example, the California Privacy Rights Act, which was approved by California voters as a ballot initiative in November 2020, modifies the CCPA significantly, further enhancing and extending an individual’s rights over their personal data and the obligations placed on companies that handle this data. The resulting new regulations became effective on January 1, 2023. Most notably, employee and business data were brought into scope, which raises the compliance requirements for us significantly, in terms of internal controls, processes and governance requirements. Furthermore, since 2020, several other U.S. states have enacted (and additional U.S. states are considering) stringent consumer privacy laws, which may impose varying standards and requirements on our data collection, use and processing activities. Continued state by state introduction of privacy laws could lead to significantly greater complexity in our compliance requirements globally, which could result in complaints from data subjects or action from regulators.

If we are not able to respond, adapt and implement the necessary requirements to ensure compliance with data privacy laws, this could adversely impact our reputation and we could face exposure to fines levied by regulators. As a result, our business, financial position and results of operations could be material adversely affected.

The reduction, modification, elimination or expiration of government incentives for, or regulations regarding, the use of energy systems and batteries could reduce demand for our products and harm our business.

Federal, state, local and foreign government bodies provide incentives to owners, end-users, distributors, system integrators and manufacturers of energy systems and batteries in the form of rebates, tax credits and other financial incentives. However, these incentives may expire on a particular date, end when the allocated funding is exhausted, or may be reduced or terminated as a matter of regulatory or legislative policy.

Table of Contents

For example, the IRA expanded and extended the tax credits and other tax benefits available to energy systems projects and the battery supply chain. We believe this law will bolster and extend future demand for our products in the United States. However, we note that implementing regulations for this law are still in process, which creates uncertainty about the extent of its impact on us and our industry. For more information, see “The Inflation Reduction Act of 2022 ("IRA") contains production tax credits for certain battery cells and battery modules. The Company's ability to benefit from Section 45X production tax credits is not guaranteed and is dependent upon the federal government's ongoing implementation, guidance, regulations, and/or rulemakings that have been the subject of substantial public interest and debate.” above.

In addition, similar incentives may exist in, or be developed outside of, the United States, which could impact demand for our products and services as we expand our business into foreign jurisdictions. Our international customers and end-users may have access to tax deductions and grants toward equipment purchases. Our ability to successfully penetrate new geographic markets may depend on new countries adopting, to the extent such incentives are not currently in place and maintaining such incentives.

General Risk Factors

There can be no assurance that we will continue to declare cash dividends at all or in any particular amounts, and any reduction in or elimination of our dividend payment could reducethe market price of our stock.

We intend to pay quarterly cash dividends subject to capital availability and periodic determinations by our Board of Directors that cash dividends are in the best interest of our stockholders. Future payment of a regular quarterly cash dividend on our common shares will be subject to, among other things, our results of operations, cash balances and future cash requirements, financial condition, statutory requirements of Delaware law, compliance with the terms of existing and future indebtedness and credit facilities, changes in federal and state income tax laws, changes in our business model and other factors that our Board of Directors may deem relevant. Our dividend payments may change from time to time, and we cannot assure you that we will continue to declare dividends at all or in any particular amounts. A reduction in or elimination of our dividend payments could have a negative effect on our share price.

We cannot guarantee that our share repurchase programs will be fully consummated or that they will enhance long-term stockholder value. Share repurchases could also increase the volatility of the market price of our stock and diminish our cash reserves.

Our Board of Directors has authorized one share repurchase program. This program authorizes the repurchase of up to $1 billion of our common stock, of which authority. The other program authorizes the repurchase of up to such number of shares as shall equal the dilutive effects of any equity-based award granted during such fiscal year and the number of shares exercised through stock option awards during such fiscal year. As of March 31, 2026, approximately $876.4 million remains available under the two programs. Although our Board of Directors has authorized these share repurchase programs, the programs do not obligate us to repurchase any specific dollar amount or to acquire any specific number of shares. We cannot guarantee that the programs will be fully consummated or that they will enhance long-term stockholder value. The programs could affect the trading price of our stock and increase volatility, and any announcement of a termination of these programs may result in a decrease in the market price of our stock. In addition, these programs could diminish our cash reserves.

We depend on our senior management team and other key employees, and significant attrition within our management team or unsuccessful succession planning could adversely affect our business.

Our success depends in part on our ability to attract, retain and motivate senior management and other key employees. Achieving this objective may be difficult due to many factors, including fluctuations in global economic and industry conditions, competitors’ hiring practices, cost reduction activities, and the effectiveness of our compensation programs. Competition for qualified personnel can be very intense. We must continue to recruit, retain and motivate senior management and other key employees sufficient to maintain our current business and support our future projects. We are vulnerable to attrition among our current senior management team and other key employees. A loss of any such personnel, or the inability to recruit and retain qualified personnel in the future, could have a material adverse effect on our business, financial condition and results of operations. In addition, if we are unsuccessful in our succession planning efforts, the continuity of our business and our results of operations could be materially adversely affected.

If our internal controls are found to be ineffective, our results of operations or our stock price may be adversely affected.

Our most recent evaluation resulted in our conclusion that, as of March 31, 2026, our internal control over financial reporting was effective. We believe that we currently have adequate internal control procedures in place for future periods, including

Table of Contents

processes related to newly acquired businesses. However, if our internal control over financial reporting is found to be ineffective, investors may lose confidence in the reliability of our financial statements, which may adversely affect our results of operations or stock price.

Changes in accounting principles and guidance could result in unfavorable accounting charges or effects, which could adversely affect our business.

We prepare our consolidated financial statements in conformity with accounting principles generally accepted in the U.S. Any change in these principles could have a significant effect on our reported financial position and financial results. The adoption of new or revised accounting principles may require us to make changes to our systems, processes and internal controls, which could have a significant effect on our reported financial results and internal controls, cause unexpected financial reporting fluctuations, retroactively affect previously reported results or require us to make costly changes to our operational processes and accounting systems upon our following the adoption of these standards. Any of these results could adversely affect our business.

To aid our cybersecurity risk management strategy, we contract with dedicated third-party firms and assessors to identify risks and threats to our organization. These assessments adhere to leading cybersecurity standards such as the National Institute of Standards and Technology (NIST) Cybersecurity Framework aligning with industry best practices. Additionally, our organization adheres to compliance with the Cybersecurity Maturity Model Certification (CMMC) and is undergoing International Organization for Standardization (ISO) accreditation, further demonstrating our commitment to adhering to rigorous cybersecurity standards. To oversee incident response and mitigation we utilize our incident response plan and processes to standardize our processes for assessing, identifying, and managing cybersecurity incidents. This includes a comprehensive reporting structure and analysis processes to provide visibility and determine incident business impact. Were a cybersecurity incident to occur, we have also implemented a cross-functional business team to aid in the determination of incident impact, severity, and materiality, with the support of standing external counsel and third-party incident response advisors. Additional to our third-party incident response advisors and support contracts, we undergo regular penetration tests to bolster our readiness in the event of cybersecurity incidents. Furthermore, we have also obtained cybersecurity insurance coverage to enhance protection and minimize potential financial losses arising from cyber threats.

We prioritize cybersecurity within our supply chain, both nationally and globally, by assessing our third-party cybersecurity posture to provide secure visibility with our partnerships. As part of our due diligence processes, we conduct security questionnaires and service provider reviews, to align our cybersecurity standards on the onset of our partnerships. Additionally, we collaborate closely with a third-party vendor to enhance supply chain resilience. This collaboration involves leveraging their expertise to inform decision-making and enhance risk oversight processes, ensuring greater robustness, and adaptability in managing supply chain challenges.

While we maintain a strong cybersecurity posture, we continuously strive for improvement and vigilance to mitigate evolving threats within this dynamic environment and protect our stakeholders’ interests. Our organization has not experienced any unauthorized access resulting from cybersecurity incidents with a materially adverse effect on our business, operations, or financial condition and we remain cognizant of the potential impact of insufficient cybersecurity measures on our operations. For further insights into additional organizational risks, please refer to the General Risk Factors section of Item 1(A) Risk Factors.

ITEM 6. [RESERVED]

Table of Contents

The following discussion and analysis of our results of operations and financial condition for the fiscal years ended March 31, 2026 and 2025, should be read in conjunction with our audited Consolidated Financial Statements and the notes to those statements included in Item 8. Financial Statements and Supplementary Data, of this Annual Report on Form 10-K. Our discussion and analysis of our results of operations and financial condition for the fiscal years ended March 31, 2025 and 2024, has been omitted from this Form 10-K and can be found in Part II, "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" of our Annual Report on Form 10-K for the fiscal year ended March 31, 2025. Our discussion contains forward-looking statements based upon current expectations that involve risks and uncertainties, such as our plans, objectives, opinions, expectations, anticipations and intentions and beliefs. Actual results and the timing of events could differ materially from those anticipated in those forward-looking statements as a result of a number of factors. See “Cautionary Note Regarding Forward-Looking Statements,” “Business” and “Risk Factors,” sections elsewhere in this Annual Report on Form 10-K. In the following discussion and analysis of results of operations and financial condition, certain financial measures may be considered “non-GAAP financial measures” under the SEC rules. These rules require supplemental explanation and reconciliation, which is provided in this Annual Report on Form 10-K.

EnerSys’ management uses the non-GAAP measures, EBITDA and adjusted EBITDA, in its computation of compliance with loan covenants and adjusted EBITDA in evaluating its financial performance. These measures, as used by EnerSys, adjust net earnings determined in accordance with GAAP for interest, taxes, depreciation and amortization, and certain charges or credits as permitted by our credit agreements, that were recorded during the periods presented.

These non-GAAP disclosures have limitations as analytical tools, should not be viewed as a substitute for cash flow or operating earnings determined in accordance with GAAP, and should not be considered in isolation or as a substitute for analysis of the Company’s results as reported under GAAP, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other companies. This supplemental presentation should not be construed as an inference that the Company’s future results will be unaffected by similar adjustments to operating earnings determined in accordance with GAAP.

Overview

The Company's chief operating decision maker, or CODM (the Company's Chief Executive Officer), reviews financial information for purposes of assessing business performance and allocating resources, by focusing on the lines of business on a global basis. The Company excludes certain items that are not included in the segment performance as these are managed and viewed on a consolidated basis. The Company identifies the following as its four operating segments, based on lines of business:

Table of Contents

•New Ventures - energy storage and management systems for demand charge reduction, utility back-up power, and dynamic fast charging for electric vehicles.

We evaluate business segment performance based primarily upon operating earnings exclusive of highlighted items. Highlighted items are those that the Company deems are not indicative of ongoing operating results, including those charges that the Company incurs as a result of restructuring activities, impairment of goodwill and indefinite-lived intangibles and other assets, acquisition activities and those charges and credits that are not directly related to operating unit performance, such as significant legal proceedings, amortization of recently acquired intangible assets and tax valuation allowance changes, including those related to the adoption of the Tax Cuts and Jobs Act. Because these charges are not incurred as a result of ongoing operations, or are incurred as a result of a potential or previous acquisition, they are not as helpful a measure of the performance of our underlying business, particularly in light of their unpredictable nature and are difficult to forecast. All corporate and centrally incurred costs are allocated to the business segments based principally on net sales. We evaluate business segment cash flow and financial position performance based primarily upon capital expenditures and primary operating capital levels.

Our management structure, financial reporting systems, and associated internal controls and procedures, are all consistent with our four lines of business. We report on a March 31 fiscal year-end. Our financial results are largely driven by the following factors:

•global economic conditions and general cyclical patterns of the industries in which our customers operate;

•changes in our selling prices and, in periods when our product costs increase, our ability to raise our selling prices to pass such cost increases through to our customers;

•the extent to which we are able to efficiently utilize our global manufacturing facilities and optimize our capacity;

•the extent to which we can control our fixed and variable costs, including those for our raw materials, manufacturing, distribution and operating activities;

•changes in our level of debt and changes in the variable interest rates under our credit facilities; and

•the size and number of acquisitions and our ability to achieve their intended benefits.

Current Market Conditions

Economic Climate

Global economic conditions are mixed with the impacts from the uncertainty surrounding U.S. tariffs, elevated interest rates and heightened geopolitical tensions having various levels of impacts in North America, China and EMEA. On February 1, 2025, the U.S. signed an executive order, effective February 3, 2025, whereby the U.S. will apply additional tariffs on imported goods from Canada, Mexico, and China. Since that announcement, the tariffs to be applied to these three countries, and others, were suspended and/or renegotiated several times with varying results and some new negotiations delayed to take effect until later dates. The impact of the U.S. tariffs and retaliatory actions by other countries could be substantial. We are currently assessing the impacts these tariffs could have on the organization, and we believe that the international nature of our organizational structure will allow us to mitigate some of the financial impact of these potential tariffs.

The war in Ukraine continues to have widespread economic repercussions, particularly in Europe. The ongoing Israel-Hamas conflict is disrupting stability in the Middle East, raising significant concerns about the potential for further escalation across the region.

Inflation in North America, China and EMEA, while more controlled compared to the sharp increases in 2023, remains a challenge despite some cooling in the U.S. and Europe through 2024 and 2025. After reducing rates three consecutive times in 2025, the Fed held the policy rate steady at 3.50%–3.75% in January 2026, citing improving economic activity and stabilizing unemployment. After several rate cuts the European Central Bank (ECB) has held their main interest rates stable since June 2025. While these are incrementally positive actions toward deflation, both economies continue to face uncertainties such as potential tariffs and policy changes from a new presidential administration in the U.S. and potential global trade frictions, macroeconomic fragmentation and geopolitical tensions the euro area. Policy actions in China signal a shift towards more proactive fiscal measures to stabilize consumption and support economic growth. While increasing travel and consumer spending due to relaxed COVID policies have provided some bright spots in 2024 and 2025, China's economy continues to face challenges from a weakened real estate market and declining exports.

The supply chain is generally stable, however, the ongoing Israel-Hamas conflict has periodically disrupted some shipments in the Red Sea. As a result, some ocean freight costs and transit times may temporarily increase until shipping in the region returns to normal. Generally, our mitigation efforts and ongoing lean initiatives have tempered the impact of broad market challenges.

The market demand in the forklift truck and Class 8 truck markets have been impacted by tariff policy uncertainty, causing some customers to pause larger projects and general spending activity until there is more clarity on global tariff impacts to their supply chains. The data center and communications markets tend to be less sensitive to tariff policy, with budget and spending plans based on their unique capital spending needs. The data center market is in the midst of a growth cycle driven by AI and increasing digitization. The communications market is currently in a modest, but slow spending recovery as investments in maintenance and network build outs are necessary to support the increased data required to be moved through their infrastructure. Global defense budgets are increasing in response to rising geopolitical tensions. Spending in EMEA has increased at a higher rate than in the US, as large program spending has outpaced sustainment spending with the U.S. Department of War.

Volatility of Commodities and Foreign Currencies

Our most significant commodity and foreign currency exposures are related to lead and the Euro, respectively. Historically, volatility of commodity costs and foreign currency exchange rates have caused large swings in our production costs. In the fiscal year 2026, we have experienced a range in lead prices from approximately $0.85 per pound to $0.95 per pound. Costs in some of our other raw materials such as steel, acid, separator paper and electronics have moderated since the middle of fiscal year 2024, but we have seen some price increases in other raw materials such as copper and antimony since the beginning of fiscal year 2026.

Customer Pricing

Our selling prices fluctuated during the last several years to offset the volatile cost of commodities. Approximately 25% of our revenue is now subject to agreements that adjust pricing to a market-based index for lead. Customer pricing changes generally lag movements in lead prices and other costs by approximately six to nine months. In fiscal 2025 and 2026, customer pricing increased due to certain commodity prices and other costs having increased throughout the year.

Based on current commodity markets, it is difficult to predict with certainty whether commodity prices will be higher or lower in fiscal 2026 versus fiscal 2025. However, given the lag related to increasing our selling prices for inflationary cost increase, on average our selling prices should be higher in fiscal 2026 versus fiscal 2025. As we concentrate more on energy systems and non-lead chemistries, the emphasis on lead is expected to continue to decline.
