MESSAGE — Félicie Burelle Chief Executive Officer In 2025, OPmobility evolved in a rapidly changing economic and political landscape. The automotive market has entered a new phase, with volumes stabilizing in Europe and North America, and the emergence of overcapacity, particularly in China. Market regionalization, supported by pricing and regulatory policies, is accelerating the growth of hybrids, along with the development of the electric vehicles market, which will continue to grow between now and 2030. In this context, innovation is being leveraged to further accessibility, a true driver of growth. Chinese manufacturers are becoming increasingly competitive. At the same time, European and American stakeholders are consolidating their positions, while also looking to differentiate themselves in key technologies: electrification strategy, autonomous driving, connectivity, and Artificial Intelligence (AI). Building on this momentum, OPmobility is fully committed to the market’s transformation and has demonstrated its resilience, underpinned by rigorous financial discipline, cost optimization, and enhanced industrial efficiency. Thanks to our portfolio “OPmobility has established itself as a player which can transform every industry change into an opportunity by leveraging technological innovation, its proximity to its customers around the world, and its agile teams.” 4 | for you, we’re transforming mobility

As a long‑standing provider of solutions for hybrid vehicles, we provide all the solutions which will accelerate the decarbonization of mobility. We also incorporate Life Cycle Assessment (LCA) and eco-design into our development processes and include more recycled and bio-based materials. Lastly, our purpose and the ACT FOR ALL™ program put a more intuitive, safer, and comfortable user experience at the heart of a sustainable mobility which is accessible to all. AI and data are also improving our operational efficiency, optimizing industrial flows, production, and anticipation of industry trends, particularly with the roll‑out of Product Life Management (PLM) infrastructure across our 40 R&D centers. To accelerate this dynamic, we have created an open innovation ecosystem, working with start-ups, laboratories, and multi-sector experts, and we are developing major partnerships, including with the Massachusetts Institute of Technology (MIT). This combined approach enables us to anticipate emerging technologies and accelerate the transition to more sustainable mobility. 2025 was testament to a robust strategy, positioning, and business model. With 152 plants in 28 countries and a diverse technology portfolio, we can meet the needs of all manufacturers and all forms of mobility. The strength of our performance reinforces the trust our partners have in us. Driven by the dedication of our teams and the synergies between business lines, we have demonstrated agility and innovation to support a shared vision of sustainable, collective mobility. 2025 Integrated report | OPmobility | 5

MARKET OUTLOOK FOR HYBRID AND ELECTRIC VEHICLES BY 2027(1) A fast-changing market BEV Hybrid and plug-in hybrid (1) Source: S&P Global Mobility LV Powertrain Forecast, February 2026. Accessibility Decarbonized mobility: a matter of accessibility The transition to a decarbonized economy is accelerating. The large-scale roll-out of electric vehicles continues to grow, while hybrid solutions are becoming more popular. To meet demand, new players in the mobility sector are developing more affordable offerings. Long-standing manufacturers, meanwhile, are tailoring their production strategy and their portfolio of car models. In Europe, governments are actively supporting this transformation through measures such as social leasing, retrofitting subsidies in France, and the reintroduction of subsidies for vehicle purchases in Germany in 2026. In China, the end of substantial state support for the electric car industry in 2025 has led to a new chapter, with Chinese manufacturers now looking to conquer the global market. The future of mobility will be more diverse. All over the world, it is becoming more sustainable, innovative, and inclusive, offering everyone the opportunity to enjoy freedom of movement. Regionalization Local presence: a strategic advantage After several decades of economic interconnection, rapid regionalization is reshaping every aspect of the automotive sector, beginning with consumer preferences. In China, connected urban vehicles are increasingly popular with users. In North America, SUVs and pick-ups are still the norm. New customs and trade restrictions and differences in regulations are prompting manufacturers and equipment suppliers to invest in production facilities closer to their markets. Europe continues to implement strong regulations, while the United States and China are accelerating their technological transition, with increasingly innovative local production. Regionalization has also led to changes in supply chains. For automotive manufacturers and their ecosystem, this new environment presents both challenges and opportunities: they must capitalize on growth wherever it occurs and create more personalized offerings which are tailored to local specificities, all while maintaining the competitive performance of their industrial model and ensuring innovation. Consequently, tomorrow’s mobility will be closer to markets, more agile, and more focused on consumers’ expectations.

Transforming mobility is, first and foremost, a collective endeavor. At OPmobility, innovation is the result of internal expertise, advances in research, and technological and academic partnerships. By making it possible for OPmobility’s experts to work with external specialists, particularly mobility and Artificial Intelligence (AI) start-ups, and share their ideas within an open ecosystem during its Innovation Days, the Group encourages innovation within the company. In doing so, it can explore new opportunities, combining its industrial expertise and entrepreneurial agility to create lighter, more efficient, safer, and more sustainable technologies. USING AI AS A TOOL TO ENHANCE INDUSTRIAL EFFICIENCY In partnership with start-ups including Dessia, Neural Concept, and Innodura, OPmobility uses AI, a powerful boost to efficiency and speed, to strengthen its testing, prototyping, and certification processes. The Group can thus accelerate the design, simulation, and validation of its products, while also improving accuracy, quality, and safety. In a sector in which manufacturers’ needs are constantly evolving, new smart solutions and tools which use AI can halve vehicle development time, depending on the region. This reduction in lead times is made possible by an ecosystem focused on open innovation. For example, in 2025, the Group’s partnership with the start-up AIRY Automotive led to the development of a new generation of lightweight battery chassis which were 3D printed using composite materials. Offering up to a 50% reduction in the weight of the mechanical part of the battery, up to 30% fewer manufacturing-related CO2 emissions, a 10% lower cost, and a 10% improvement in vehicle range, it received Plug and Play’s Global Innovation Award in 2025.

INNOVATING TO CREATE VALUE FOR ALL This progress reflects OPmobility’s firmly held belief that innovation is only effective when it creates value for all stakeholders (customers, users, employees, and the planet) and involves the entire mobility ecosystem in its transformation. Because of this dynamic approach, the Group is able to capitalize on its expertise to continuously refine its solutions: not only from a technological standpoint to pave the way for safer and more sustainable mobility, but also from a social and urban perspective to make it more accessible and accommodate new uses and new forms of mobility around the world. Its aim is to enable everyone to travel, no matter what their needs might be, and enjoy the freedom which mobility brings, while also being environmentally friendly.
