In 2024, OPmobility proved the merits and demonstrated the success of its long-term strategy and developed a profitable growth model based on innovation, complementary expertise and the diversification of its international presence. Once again, the Group improved all its results in 2024. To meet the needs of our long-standing customers and expand into new markets, we have considerably broadened our offerings in lighting, battery electric vehicles, hydrogen vehicles and on-board intelligence. Underpinned by the dynamism of our long-standing activities, the development of these new growth drivers is a key part of our strategy, enabling us to support the major transformations of the mobility industry. Over the last 80 years, the Group has always been known for its ability to adapt to a changing world. That’s why we have fundamentally transformed from a diversified industrial Group to become a world leader in sustainable mobility in all its forms. That’s what we chose to express by changing our name to OPmobility in early 2024. This name pays tribute to our past and our values, while looking to the future with our teams, our customers and our shareholders. With the support of our governance and its leadership and the dedication of our 39,000 employees around the world, we are looking to the future with confidence and determination as we pursue a long-term investment and innovation policy in response to current technological and geopolitical shifts. Our strong and dedicated majority shareholder base supports this strategy. “As a leader in sustainable mobility, OPmobility developed a profitable growth model and successfully pursued its transformation in 2024, enabling it to look to the future with confidence.” MESSAGE FROM LAURENT BURELLE Chairman of the Board of Directors of OPmobility

In 2024, OPmobility confirmed its position as a leader in sustainable mobility. Throughout the year, our Group reported strong financial and operating performance, in a difficult market, characterized by low production volumes within the automotive industry and lower-than-expected sales of electric vehicles. We outperformed the market in all the regions in which the Group operates, while continuing to pursue growth in all our activities. These figures are the result of the unwavering commitment of the Group’s 38,900 employees and confirm the importance of our strategy, focused on the 3 pillars of diversifying the Group’s technologies, global presence and customers. With a stronger and diversified portfolio of products and technologies, we have accelerated our international development, primarily in the United States, which is now our biggest market, and Asia. New customers have trusted us with their business, from new players in electric and autonomous mobility to heavy and commercial mobility manufacturers. These strategic successes are underpinned by the operational and commercial successes of our Business Groups. Exterior significantly increased its sales and received a considerable number of orders, particularly in the United States and China. Lighting finished the year with a full order book and plans to launch 60% more projects in 2025 than it did in 2024. The profitability of our Modules activity improved sharply in 2024, strengthening the activity for the coming years. C-Power, which produces fuel tanks, also had a good year, continuing to improve market share within the shrinking thermal vehicle market. Lastly, H2-Power, our hydrogen activity, enjoyed significant commercial success in 2024, particularly with trains and buses. By demonstrating unprecedented adaptability and strengthening both our competitiveness and our operational excellence, we efficiently accelerated our transformation strategy to contribute to more sustainable mobility which is accessible to all. Just what we need to face the challenges of 2025 and beyond with confidence and enthusiasm! “In a market environment which continued to be challenging in 2024, we successfully combined performance and growth, without losing sight of our strategic focus.” LAURENT FAVRE Chief Executive Officer of OPmobility MESSAGES

In response to the large-scale and rapid transformation of our industry, we are focusing all our energy on turning these changes into opportunities which will benefit our customers, society and future generations. We are committed to innovation, because innovative solutions are essential if we are to rise to the formidable challenge of sustainable mobility, while continuing to offer products and solutions which are accessible to the widest possible audience. That’s the objective behind our approach to innovation: sharing expertise between Business Groups, as we do at our Innovation Days, and working with an entire ecosystem of academic partnerships and start-ups. We kicked off 2025 at the Consumer Electronics Show (CES) in Las Vegas, attending the event for the first time as OPmobility. At the heart of the world’s most powerful innovation event, we confirmed our position as a major technology partner of a new generation of mobility. Innovation also means being able to provide our customers with increasingly customized and differentiated solutions. That’s the idea behind One4you, our integrated offer for vehicle exteriors which combines our expertise in exterior body parts, lighting, modules and software. With One4you, we are reinventing our relationships with our customers, providing customized and innovative technological solutions which will make them more competitive. Lastly, we are more focused than ever on sustainable development because tomorrow’s mobility must be more environmentally friendly for the planet and its inhabitants. Inspired by our purpose of “Driving a New Generation of Mobility”, we have reached new milestones this year in terms of the energy transition, which are vital to ensure the future we all want. In 2025, OPmobility’s operational activities will be carbon neutral. And we will continue to implement our roadmap to carbon neutrality to achieve our objectives across our entire value chain, providing a growing number of solutions for low-carbon powertrains and recycled materials. “More than ever, innovation is the driving force behind the transformation of mobility. We must act quickly to provide our customers with increasingly disruptive solutions.” FÉLICIE BURELLE Managing Director of OPmobility

TREN D 1 CONSTANTLY EVOLVING MOBILITY An automotive market in an uncertain climate Between 2019 and 2022, the global automotive market was confronted with successive crises – the pandemic, a shortage of semi-conductors, geopolitical tensions, a slowdown in growth and inflation, leading to low volumes. The market was also affected by slower-than-expected electrification and consumer uncertainties about which technology to choose. After volumes rose in 2023, global automotive production amounted to 86.8 million vehicles in 2024. The electrification of global automotive production is gathering pace in a declining market — In millions of vehicles 85.9 + 3.6% + 7.6% + 10% – 1.2% 71.6 74.2 79.8 86.8 87.8 94 Electric 42% Hybrid 33% Thermal 25% 12% 21% 67% (1) A vehicle with features and functions which are primarily enabled through software.

TREN D 3 TREN D 2 The age of agility A hyper-competitive environment An uncertain regulatory environment In Europe, Germany stopped providing financial support for electric vehicle purchases in late 2023, France has reduced financial aid for the low-cost leasing of electric vehicles and there is no single Europe-wide approach to boost investment in the industry. However, regulations, particularly the CAFE* standard, are forcing manufacturers to make ever greater efforts and investments, with a planned phase-out of combustion engines in 2035. In the United States, the Inflation Reduction Act boosted investment across the industry. A wide range of technologies Traditional combustion engines, combustion engines powered by alternative fuels, battery vehicles, hydrogen-powered vehicles: manufacturers, consumers and governments are faced with different technologies which continue to coexist. *The European CAFE (Corporate Average Fuel Economy) standard aims to reduce the fuel consumption and carbon dioxide emissions (CO2) of motor vehicles. In 2025, the aim is to reduce the global average to 93.6 gCO2/km per new vehicle sold (electric, plug-in hybrid, hybrid, thermal). The world’s leading electric vehicle manufacturer is now BYD, a Chinese manufacturer which overtook the American company Tesla in late 2023 Top 5 electric manufacturers in 2024 — In automotive production market share New players Long-standing automotive manufacturers are facing unprecedented disruption to the market and consumer habits. In this landscape, new players, driven by the development of electric vehicles, have emerged and are now well-positioned, with very short development cycles of between 18 and 24 months. Today, China is the world’s leading automotive manufacturer (29.6 million vehicles in 2024, all powertrains combined) and the leading manufacturer of battery electric vehicles (7.6 million vehicles in 2024). The country has wide-ranging expertise across the entire electric vehicle value chain, from the extraction and refining of critical raw materials to the production of batteries.

EMBRACING ALL FORMS OF MOBILITY

In a rapidly changing market, OPmobility has established a clear roadmap, focused on three key areas: diversifying its technologies, global presence and customers. The Group has opted for innovation, agility and proximity to seize all future opportunities and contribute to more sustainable, safer and more affordable mobility.

To seize opportunities and anticipate global market trends, the Group is expanding and strengthening its technology offerings. In this way, it can cater to the needs of end customers, whatever their choice of powertrain, whether electric (hydrogen or battery), hybrid or thermal. The objective? To develop our portfolio by strengthening our long-standing technology leadership in exterior body parts, fuel tanks and complex models and through targeted acquisitions to incorporate new areas of expertise. As such, over the last three years, the Group has made major acquisitions in lighting, hydrogen and batteries, sectors which are complementary to our long-standing activities. To innovate in software, as vehicles become increasingly connected, the Group created OP’nSoft in 2023. Focused solely on on-board software, this entity provides integrated solutions and services with which to support our customers as they move towards the Software Defined Vehicle. In addition to our efforts to strengthen our technology offerings, we have embarked on increasing digitalization across our sites, capitalizing on the power of Artificial Intelligence to improve our manufacturing processes. Modeling, simulation, image processing: by using AI, the Group can make the most of available data to monitor the quality of our parts and the quantity of material inputs as closely as possible during the manufacture of our products. STRENGTHENING our technology leadership The mobility of today and tomorrow is multi-faceted: OPmobility has therefore made technological diversification its first strategic pillar.

Thermal, battery electric, hydrogen: OPmobility’s technology portfolio provides support for all mobility players. At OPmobility, we believe tomorrow’s mobility will be multi-faceted and widely available, but only if all technological options are explored. What will the world’s automotive fleet look like in 20 years? Although there will be lots more battery vehicles, we believe combustion engines will still be a reality, perhaps powered by alternative fuels. Hydrogen, which combines the advantages of an electric vehicle (no CO2 emissions) and a combustion engine vehicle (extended range and rapid refueling), could therefore play an important role in the decarbonization of mobility, particularly heavy and commercial mobility. The challenges of decarbonization require different approaches in different regions. OPmobility has therefore chosen to continue producing fuel tanks, maintaining its annual production of some 17 million parts for combustion engine, while investing in innovations for battery electric vehicles and hydrogen. New milestones for hydrogen in 2024: increased industrial capacities OPmobility invested very early in hydrogen, beginning in 2015, and has adapted its solutions to the specificities of this promising energy carrier. In France and Europe, this strategy has enabled the Group to meet the needs of automotive manufacturers, including Stellantis and Hyundai Motor Company, and rail mobility players, such as Alstom and Stadler. The Group is responding to invitations to tender for heavy mobility in China and the United States, including invitations from Ford. EXPERT UNDERSTANDING OF TECHNOLOGICAL DIVERSITY, A DISTINCTIVE ADVANTAGE

The Last Man Standing strategy In view of the decline of the combustion engine market, OPmobility is safeguarding its future with its Last Man Standing strategy: this positions the Group as a key partner for its customers, thanks to its expertise, its capacity, its operational excellence and its supply chain continuity. As such, in a consolidating market, the Group is adapting and plans to strengthen its position as the global leader by increasing its market share from 22% to 30% by the end of the decade. x7 between 2026 and 2030: the expected growth of the global hydrogen mobility market Europe’s biggest hydrogen vessels plant In its brand new plant in Compiègne in France, the Group is launching production of high-pressure hydrogen storage systems for heavy and public mobility, near a former fuel tank. All employees on this historic site have been trained to manufacture hydrogen vessels. This is a wonderful example of a technological and people-centered transition. In 2025, OPmobility will launch production of high-pressure vessels for Hyundai in its South Korean plant in Wanju. New OPmobility plant to produce high-pressure hydrogen storage systems in Lachelle, France.

BALANCING our global presence Today, Europe accounts for half the Group’s revenue. While maintaining its long-standing European focus, OPmobility has committed to its international expansion by accelerating its development in North America and Asia. This is the second pillar of its strategy. Within the new global landscape of mobility, OPmobility is strengthening its international presence in growing mobility markets, particularly the United States, China, India and South-East Asia. In the United States, the Group has a network of 12 plants, the most recent of which was opened in Austin (Texas) in 2024; it supplies the leading electric vehicle manufacturer in America with front-end modules and cockpit modules. With a well-established presence in China, including 37 plants and 5 R&D centers, the Group is ready to capitalize on opportunities with local partners, particularly in view of the growing momentum of the hydrogen sector. In India, a regional hub which brings together several of OPmobility’s activities was opened in 2024 in Pune, in the state of Maharashtra, one of the country’s biggest automotive hubs. Two new plants will also be added to the existing network. OPmobility’s strategy, focused on 3 pillars, including global diversification, presented in relation to the Group’s annual results in 2024, by Laurent Favre. STRATEGIC PILLAR #2

In addition, we plan to open 2 other plants, including one in 2025. The opening of a new R&D center in Pune in 2024 was a milestone for the Group’s operations in India. Pune is one of the Group’s 3 existing regional hubs, along with Troy in the United States and Tangiers in Morocco, which bring together engineering teams from all 4 Business Groups at OPmobility.

Two new state-of-the-art sites The construction of a new 40,000 m2 plant, the Group’s biggest plant in the country, will make it possible to supply exterior body systems for the domestic automotive market. In total, nearly 500 new jobs will be created in one of the country’s most important technological and industrial hubs. Opening in 2025, the site will eventually produce up to 1 million automotive parts every year. In addition, the new R&D center, designed for up to 600 engineers, is strengthening and combining the Group’s research capabilities in lighting and exterior body systems. A sustainable innovation hub The Group’s strategy in the country is supported by talented Indian engineers, growing demand and significant logistical capabilities. It is also aligned with the Make in India initiative launched by the Indian government, which aims to attract foreign investment and position the country as a leading industrial hub. The Group’s ambition in India is not just to provide long-lasting, quality products to meet local needs, but also to improve our overall competitiveness in engineering and industrial production in all the Group’s countries. The Group is confident that India will become a leading hub for technological innovation and sustainable mobility. In India, we want to develop hydrogen storage solutions, along with smart and lightweight materials, reflecting the country’s commitment to more sustainable mobility. This strategy will make OPmobility a major player in the transformation of the Indian automotive industry.

In 2024, the United States became OPmobility’s largest market and a key focus for the Group, which plans to double its revenue in the country by 2028, building on solid foundations. Having operated in the United States for almost 50 years, OPmobility is one of the country’s leading mobility companies and has become a key partner of the “Big Three” (Ford, General Motors and Stellantis), for which it produces more than 50% of gasoline fuel tanks. The American market has evolved considerably and is very dynamic today. GDP per capita and the level of car ownership in the United States are almost double those of France. Focused on innovation, the United States is at the forefront of the mobility revolution, thanks to investors who are keen to support the increasing maturity of connected and autonomous vehicles. In this competitive market, which is still dominated by combustion engines, OPmobility is able to support the development of all types of powertrain: thermal, hybrid, battery electric and hydrogenpowered. In addition, the majority of our activity, which is focused on exterior systems and models, is unaffected by changing trends in powertrains. With the opening of a new plant in Texas in 2024 to supply the country’s leading electric vehicle manufacturer with modules, all the Group’s Business Groups (Exterior & Lighting, Modules, C-Power and H2-Power) now operate on American soil. The Group therefore has the means to support its ambitious vision: OPmobility, which generates almost 16% of its revenue in the United States, aims to double its revenue in the country by the end of the decade. The Group intends to achieve this growth in the automotive sector and in other forms of mobility, including trucks and rail. 89% increase in GDP per capita in the United States, between 2014 and 2024, compared to +46% in Europe OPmobility in the United States 12 plants 6 R&D centers 3,300employees 16% of revenue OPMOBILITY AT THE HEART OF AMERICA’S DYNAMIC MOBILITY MARKET

In Austin, manufacturing excellence for the electric mobility sector In 2024, OPmobility marked a major milestone in its American development with the opening of its first plant in Austin, Texas. This new module assembly plant was opened to fulfill a long-standing order with a major American player in electric mobility. Built in just a few months, the Texan site has already produced 100,000 modules since September 2023. With a capacity of 2.5 million modules (1.5 million front-end modules and 1 million cockpit modules) and more than 400 employees as of 2025, it will soon become the Group’s largest plant in terms of revenue, expanding its activities to produce exterior body parts, such as tailgates. QUESTIONS FOR… What impact is electrification having on the Group’s C-Power activity in the United States? By 2030, electric vehicle penetration should reach 30%; this leaves a significant market share for combustion engines. At a time when our customers are reducing their gasoline engine engineering teams or redeploying them to focus on electric vehicles, we continue to offer a core range of key expertise in combustion engines which our customers are going to need. As such, we are ready to continue equipping thermal vehicles, including hybrid vehicles, while also targeting the electric market, via our e-Power battery activity. Are there any other opportunities? Of course! The market is transforming and we are adapting, as we always have. For example, to equip hybrid vehicles, we are working on new concepts to create innovative pressurized tanks which are lighter and more competitive. And, to provide further opportunities for our manufacturing sites, we have also begun to diversify into new products, such as recreational vehicles, quads and underwater scooters, which operate with gasoline tanks. By 2027, this market alone will account for 500,000 vehicles. “The combustion engine market still offers opportunities which we are ready to seize.” YOUSSEF SOUIBA Executive Vice President of OPmobility, President of the C-Power Business Group

Today, long-standing manufacturers account for half of OPmobility’s revenue. In a rapidly changing automotive market, the Group is implementing a strategy to provide an agile response to very wide-ranging customer needs. The challenge? Maintaining and developing our existing portfolio, while adapting our products and services to new players, particularly in North America and China, which are much more vertically integrated and which drive us to innovate, both in terms of our technologies and our practices. Moreover, OPmobility is looking beyond the automotive world to heavy mobility players, including leaders like Alstom and Siemens, and is developing battery electric and hydrogen solutions to support the sustainable transition of trains, tramways, trucks and buses. DIVERSIFYING our customer portfolio In a mobility market undergoing a radical transformation, new players are emerging, notably in North America and Asia, and new opportunities are arising, particularly when it comes to decarbonized heavy and public mobility. OPmobility’s third strategic pillar is focused on expanding the Group’s customer portfolio to meet all mobility needs. OPmobility’s strategy, focused on 3 pillars, including customer portfolio diversification, presented in relation to the Group’s annual results in 2024, by Laurent Favre. STRATEGIC PILLAR #3

NEED TO KNOW A strong portfolio of long-standing customers Increased customer diversification, including electric vehicle players in the United States and China Development in heavy, public and commercial mobility (trucks, buses and trains)

The challenge of decarbonizing rail transport Today, a large proportion of the world’s rail networks are not electrified, including 95% of lines in the United States, 40% in Europe and 28% in China. At present, diesel-powered trains operate on these lines. To decarbonize rail transport, operators are increasingly turning to hydrogen trains. Compatible with all kinds of lines, hydrogen trains do not require significant investments in infrastructure. And with considerable range and short refueling times, these trains are a powerful boost to the energy transition and offer major growth potential. In July 2024, Stadler chose OPmobility to equip its first hydrogen trains in Europe. This major contract, signed with one of the world’s leading rail manufacturers, confirms OPmobility’s technology leadership in a growth sector. LEADING RAIL COMPANIES ARE CHOOSING OPMOBILITY’S HYDROGEN SOLUTIONS OPmobility and hydrogen 15 Stadler trains equipped by 2025 8 350 bar high-pressure storage systems per train, equivalent to 185 kg of on-board hydrogen The latest trends and innovations at OPmobility in the rail market, presented at InnoTrans 2024.

Combining energy storage and generation In July 2024, OPmobility signed a contract with Stadler to equip 15 hydrogen-powered trains for use on regional lines in Italy. As a pioneer in hydrogen technologies, operating across the value chain of this energy source, the Group will also be responsible for the development and industrial production of 350 bar high-pressure hydrogen storage systems and 150 kW fuel cell systems. Featuring an optimized design, these compact systems include NM12 Twin fuel cell stacks from the joint venture EKPO(1). To power the trains’ electric motors, they will instantly generate electricity from hydrogen stored in the tanks and oxygen in the air. What’s more, these hard-wearing systems will stand up to intensive use. This is just the beginning: in addition to the 15 trains which will be equipped by 2025, OPmobility plans to expand its deliveries in the coming years. With a strong order book and increased manufacturing capacity in Europe and Asia, we are ready to respond to our customers’ growing needs which will characterize the transformations which lie ahead. (1) EKPO Fuel Cell Technologies is a joint venture between ElringKlinger (60%) and OPmobility (40%). OPmobility hydrogen systems on board Chinese tramways With its joint venture PO-Rein, OPmobility signed a contract in 2024 with the world’s leading railway manufacturer, CRRC (China Railway Rolling Stock Corporation Limited), becoming the first technology partner to sell its high-pressure storage technology for rail mobility. The contract covers the delivery and commissioning of 76 type 4 high-pressure storage systems, a leading technology in terms of quality and performance. These systems will be used in the latestgeneration smart tramways which provide public transport in the city of Kuching in Malaysia. These autonomous tramways can transport more than 300 passengers and do not require any specific infrastructure: they follow a route defined by a virtual track on the ground. Hydrogen-powered, they take just 10 minutes to refuel, have a range of 245 kilometers and can reach a top speed of 70 km/hour.

Tomorrow’s mobility will be sustainable. In 2022, OPmobility merged its People and Sustainability departments, recognizing that new generations – from employees and customers to consumers and citizens – expect companies to take greater social, societal and environmental responsibility. As a company which is committed to and a firm believer in decarbonization, OPmobility works closely with its stakeholders and its employees.
