NTT DATA Business Solutions AG Sustainability Report 2024/2025 About this report 3 T he 2024/2025 Sustainability Report underscores our commit- ment to transparent and responsible business practices by presenting our sustainability strategy, performance, and progress across global operations and supply chains. Report Profile Approval and publication Independent assurance Reporting period and scope This report covers the fiscal year 2024/2025 (April 1, 2024 – March 31, 2025) and additionally reflects signifi- cant activities up to the editorial closure. The scope includes all countries and subsidiaries of NTT DATA Business Solutions AG. The report has been approved by the Executive Board and Supervisory Board of NTT DATA Business Solutions AG. It is available digitally in German and English, with further information accessible on our website and in the 2024/2025 Annual Report. To ensure credibility and reliability, selected data points and disclosures – particularly greenhouse gas emissions – have undergone limited assurance by an independent third party. The process included: • Evaluation of data accuracy, reliability, and consistency Reporting standards and ESRS transition and approaches Calculation methods and assumptions • Assessment of internal controls and documentation Data and Assurance • Review of GHG emissions calculation methodologies As in previous years, disclosures are primarily oriented towards the German Sustainability Code (GSC). Our GSC Declaration can be accessed via the GSC online database. In parallel, we have begun a structured tran- sition toward the European Sustainability Reporting Standards (ESRS), starting with voluntary alignment on two major topics: ESRS E1 – Climate Change ESRS S1 – Own Workforce Calculation methods are noted with each indicator. Figures reflect the best available information at the time of publication. Forward-looking statements are based on assumptions at editorial closure and may change due to uncertainties and external factors. This external assurance strengthens stakeholder trust and reflects our commitment to transparent, high-qual- ity reporting. We plan to expand the scope and depth of assurance in future reports as part of our continu- ous improvement efforts.

NTT DATA Business Solutions AG Sustainability Report 2024/2025 Forword 5 In the past fiscal year, we reduced our carbon foot- print from 14,302 to 13,792 tons of CO2 equivalents – a decrease of 3.6% – despite double-digit revenue growth of 15.4%. Norbert Rotter Chief Executive Officer NTT DATA Business Solutions Mr. Rotter, Ms. Czymek-Lauer, the European Commission recently introduced new regulations to ease sustainability reporting requirements. Do you welcome this? NCL: I can only confirm that. Now it is about support- ing our colleagues even more in integrating sustaina- bility into processes and everyday practices. Norbert Rotter (NR): First of all: we started reporting before it became a legal requirement. We do it because it’s the right and sensible thing to do. But simplifica- tions are certainly desirable. The detailed requirements tie up significant resources, leaving sustainability man- agers too little time to contribute substantive ideas. That cannot be the point of it all. Nicola Czymek-Lauer (NCL): We welcome the fact that simplifications are planned. At the same time, we will continue to increase transparency and work intensively to ensure that our growth does not come at the expense of future generations. It is certainly helpful if we can focus more on what really matters. Mr. Rotter, you already mentioned your early start: this year NTT DATA Business Solutions is presenting its third Sustainability Report. How has it improved compared to the first report? NR: Over the past years, we have learned a lot and made great progress. Our first report contained data from only a few countries; in 2024 we published Group- wide figures for the first time. This year, we were able to add even more data points and thereby significantly increase the report’s informative value. Data collection and analysis with innovative software Can you give concrete examples of progress in transparency? NR: We no longer compile environmental data from our offices and data centers in Excel spreadsheets, but in our self-developed Sustainable Buildings Platform. This reduces errors, increases efficiency, and supports us in planning emission reductions. NCL: Another important step is that we are now also recording information about our Scope 3 emissions… …meaning emissions from your supply chain – for example, from purchased IT equipment or business travel? NCL: Correct. This is a major challenge because many of our service providers and suppliers still cannot provide meaningful data. But, thanks to specialized databases, we can rely on robust average values and thus approximate our actual Scope 3 emissions.

NTT DATA Business Solutions AG Sustainability Report 2024/2025 Foreword 6 Our main task is to set the targets and ensure trans- parency. Our subsidiaries therefore receive detailed scorecards on their emis- sions data. Nicola Czymek-Lauer Chief Financial Officer NTT DATA Business Solutions What share of your total emissions does Scope 3 represent? How much of your electricity needs do you now produce in Bautzen? NCL: In this fiscal year, just under 89%. That is not unusual, as Scope 3 makes up the largest share of total emissions in most industries. More independence from the energy market This year, you can report Group-wide develop- ments for the first time. How far have you come in reducing Scope 1 and Scope 2 emissions, which mainly result from energy consumption and your vehicle fleet? NR: In the past fiscal year, we reduced our carbon foot- print from 14,302 to 13,792 tons of CO2 equivalents – a decrease of 3.6% – despite double-digit revenue growth of 15.4%. The so-called emissions intensity dropped even more sharply: per million euros in revenue, we emitted 7.5 tons of CO2 equivalents, down 16%. How do you plan to reduce your footprint further? NCL: A central lever is sustainable energy supply – especially increasing the share of renewable electricity. At our Bautzen site, we recently commissioned a new photovoltaic system with the aim of increasing our self-generation of renewable electricity. A great exam- ple of how economic efficiency and climate protection can go hand in hand. NCL: The system is designed for an autonomy level of 33%. We are currently considering investing in an energy storage solution that could raise this figure to around 50%. That would make us even more independ- ent of energy price fluctuations – a clear competitive advantage. The investment will likely pay off within seven to eight years, somewhat faster than initially expected. Context-driven action by local leaders NTT DATA Business Solutions has traditionally relied on the initiative of managers and employees. Are there nevertheless specific targets for emissions reduction? NR: Yes. Together with NTT DATA, we have defined clear Group-wide targets – of course, also for NTT DATA Business Solutions. But in line with our corporate culture: local managers are expected to decide them- selves which measures are most effective and feasible in their regions. We in Germany cannot accurately judge what works best elsewhere. NCL: Our main task is to set the targets and ensure transparency. Our subsidiaries therefore receive detailed scorecards on their emissions data. We have also appointed sustainability managers in all units to systematically drive the topic forward.

NTT DATA Business Solutions AG Sustainability Report 2024/2025 Foreword 7 Concretely: how fast should the carbon footprint and emissions intensity decrease? Speaking of software solutions: what are your expectations for your new product “Sustainability Data Simplified”? NCL: Like the entire NTT DATA Group, we aim to reach net-zero across the value chain by 2040. In just ten years, by 2035, we want to reduce our direct and indi- rect operational emissions to net-zero. Diversity is more than the share of women Ms. Czymek-Lauer, with your appointment the Executive Board is now 50% female. Are there further diversity goals for management levels? NCL: Yes. At the two levels below the Board, we want to reach 20 and 25% women by 2028. However, I would emphasize: diversity is about much more than gender. It’s about bringing together people with different per- spectives and ways of thinking. This is also important from a business standpoint because diverse teams are more successful. Let’s come back to sustainability reporting, which is also increasingly relevant to your customers. Do you see it as a business opportunity? NR: Absolutely. Our customers – even mid-sized ones – increasingly rely on sustainability reporting, often independently of legal requirements. They therefore need innovative software solutions to collect, aggre- gate, and analyze data. Here, we can add value to the SAP ecosystem with our own software solutions, based on our reporting experience. In this way, we support not only digital but also green transformation. NR: This is a classic example of software that strategi- cally complements the SAP ecosystem and creates clear added value for our customers. It enables them to precisely calculate and analyze sustainability metrics for individual products – for example, their carbon footprint. We therefore want to further expand our business with self-developed software – in sustainabil- ity and beyond. Artificial intelligence serving people Can artificial intelligence simplify and improve sustainability reporting? NCL: Yes, AI technologies offer huge potential here. I will focus in the coming months and years on how we can improve transparency in reporting and risk management with innovative tools. NR: Beyond that, AI increasingly supports companies with social or ecological impact. Particularly exciting is our Danish colleagues’ AI Hospital Assistance Project: with our Digital Human Platform PARSONII, patients and visitors can turn their smartphones into compan- ions that guide them through hospitals and answer questions. The next step is helping seriously ill patients use digital tools at home to manage and share their health data without technical knowledge. Last year, you, Mr. Rotter, published the book Ignite 2034, in which experts explore what the world might look like in 2034. Abhijit Dubey, Global CEO of NTT DATA Inc., contributed a chapter on photonics – a technology that could simplify data transmission and massively reduce energy consumption. Do you already have concrete expectations? NR: It’s too early for that. What matters to me is that we don’t just look at the next few years but further ahead. What sounds like science fiction today may transform our world and our business tomorrow. That’s why we systematically deal with future technologies. And we benefit greatly from being part of the NTT Group, which drives exciting development projects. NCL: We are both convinced: technological innovation is key to tackling challenges. That is why it is important not only to recognize risks but also to focus on oppor- tunities. Mr. Rotter, Ms. Czymek-Lauer, thank you very much for this conversation.

These pillars frame our Group-wide ambition to create measurable impact for the environment, society, and the economy, and they guide both internal actions and the services deliv- ered to clients. • Planet Positive NTT DATA commits to regenerating ecosystems and acting on climate change. This includes pursuing its Net-Zero Vision 2040, expanding renewable energy use, innovating around circular economy solutions, and embedding climate-friendly practices into our services and solutions. The company seeks to mini- mize its own footprint and help customers lower emissions and manage environmental risks. Three pillars of the sustainability strategy Planet Positive Prosperity Positive People Positive Lead by example, to disrupt industries for good, innovating services and solutions to regenerate our planet Transform businesses and society for success- ful growth, with sus- tainable services and solutions Shape a better world for all, applying our digital capabilities to improve livelihoods and contribute to an inclusive society

NTT DATA Business Solutions AG Sustainability Report 2024/2025 Sustainability 14 • Prosperity Positive Materiality Key progress included: NTT DATA aligns its business growth with sustainable economic development. The focus is on providing sustainable IT and consulting services, strengthening trust in value chains, and innovating responsibly. This ensures that customer transformation projects and the company’s own growth contribute to fair, inclu- sive, and long-term prosperity. NTT DATA Business Solutions operates in the global IT services and consulting industry, with a strong focus on SAP and related enterprise applications. Our sus- tainability approach is shaped by the specifics of our industry environment and by diverse local, social, and regulatory contexts in the countries where we operate. • Expansion of the scope of Double Materiality Assessment (DMA) from NTT DATA Business Solutions to NTT DATA Inc. and the NTT DATA Group • Internal stakeholder engagement with relevant Group departments for a structured evaluation of the identified IROs by functional experts • Alignment with regulatory requirements under • People Positive Double materiality assessment the CSRD The company leverages its digital expertise to foster an inclusive and equitable society. This covers employee well-being, diversity, equity and inclusion (DEI), respect for human rights, and digital accessibility initiatives that broaden access to technology. Community engagement, skills training, and responsible work- place practices are also integral to this pillar. In fiscal year 2022/2023, we identified nine material topics. In 2023/2024, we initiated the integration of the double materiality concept into our reporting, aligned with the European Sustainability Reporting Standards (ESRS). During this reporting year, we continued this process in close cooperation with NTT DATA Inc. • External stakeholder engagement with renowned authorities in the fields of corporate responsibility and sustainable development • Alignment with the three pillars of our Group-wide strategy • Request for resolution by the Board of Directors of NTT DATA Group Together, these three pillars guide our environmental and social responsibilities. By linking sustainability with innovation and long-term business value, the pillars ensure that our strategy remains relevant, ambitious, and growth-oriented. An enhanced version of our strat- egy will be released to reflect the updated materiality analysis, developed for the first time in a holistic approach across the entire NTT DATA Group. Nine material topics pursued by NTT DATA Business Solutions E = Environment S = Social G = Governance • Climate Change & Emission Reduction • Circular Economy & Resource Use • Talent Management & • Responsible Technology Engagement • Diversity, Equity & Inclusion (DEI) • Business Ethics & Compliance • Data Privacy & Cybersecurity • Protection of Nature & • Human Rights Biodiversity

NTT DATA Business Solutions AG Sustainability Report 2024/2025 Sustainability 15 Scope 3 emissions. Our supplier relationships influ- ence environmental and social standards beyond our own operations. • People and human rights impacts: We offer a safe reputational damage, penalties, and business loss. These risks are amplified by the increasing sophistica- tion of cybercrime, and the growing reliance on cloud services. • Workforce risks: Talent shortages, competitive labor markets, and workload pressure can increase turnover, disengagement, and costs, especially for specialized IT skills. Opportunities At the same time, sustainability challenges create opportunities for innovation and growth: • Digital sustainability solutions: Expanding services in carbon accounting and ESG data management support client goals, while AI-enabled social innovation projects, such as the AI Hospital Assistance, create a societal impact and open new growth markets. • Renewable energy: On-site renewable electricity generation reduces costs and grid dependence, while sourcing via power purchasing agreements and green tariffs add price stability and resilience. • Fleet and mobility transition: Electrification of vehicles and incentives for low-carbon commuting directly reduce emissions while improving our employer brand. • Efficient data centers and IT: Using energy-efficient technologies and sustainable hardware lowers emis- sions and enhances competitiveness in a market where clients demand climate-conscious IT. • Supplier collaboration: Partnering with suppliers to decarbonize goods and services enhances compliance readiness, client trust, supply chain stability, and market competitiveness. Material topics Final approval of the DMA result by the NTT DATA Group Board of Directors was granted during the preparation of this report. The newly approved 13 material topics are not yet presented here, as incorporating them would require significant structural changes to this report. Therefore, this year’s report continues to use the nine previously identified material topics as the guiding framework for our sustainability management. Material impacts, risks, and opportunities Our DMA confirmed that sustainability issues affect NTT DATA Business Solutions both inside-out (impacts on the environment and society) and outside-in (risks and opportunities affecting business resilience). The following summary of our impacts, risks and opportu- nities (IROs) reflects our nine established material topics, enriched with insights from this reporting year. Impacts Our business model generates environmental and social impacts that we actively manage across four key areas: • Environmental impacts from our own operations: and secure place to work for more than 16,700 employees worldwide, ensuring fair working condi- tions, health and well-being, training, and diversity. We also safeguard human rights in our supply chain, where risks such as long working hours, restricted association, or unfair treatment may occur. • Community impacts: Through donations, volunteer- ing, and social initiatives, we contribute to education, digital access, and reforestation, creating benefits that extend beyond our business operations. Risks Sustainability-related risks cover environmental, regu- latory, operational, and social areas: • Climate and energy risks: High energy demand, energy price volatility, and exposure to extreme weather may increase costs and the risk of opera- tional disruptions. In addition, increasing regulatory and reputational pressures to reduce our carbon footprint can undermine long-term competitiveness if not managed properly. Our offices, data centers, and vehicle fleet contribute to greenhouse gas emissions and resource consump- tion. Efficiency measures and renewable energy sourcing can reduce negative effects and generate positive outcomes. • Regulatory risks: Statutory compliance requires robust due diligence, supplier monitoring, and reliable reporting from all countries and subsidiaries. Non-compliance could result in penalties or reputa- tional damage. • Value chain impacts: Purchased goods, services, and • Cybersecurity and data privacy risks: System business travel are significant contributors to our breaches or loss of personal data could cause severe

NTT DATA Business Solutions AG Sustainability Report 2024/2025 Sustainability 19 our preparations to meet CSRD requirements. In addition, selected data sets, such as for greenhouse gas emissions, have already been subject to voluntary external assurance, providing an additional layer of credibility beyond the internal three lines of defense. Details of topic-specific rules, measures, and processes are described in the respective chapters of this report, illustrating how oversight translates into practice. Rules and Processes Our sustainability governance follows the three lines of defense model, which defines clear responsibilities and robust control mechanisms: 1. First line – Local business units and global functions are responsible for collecting accurate data, implementing measures, and complying with defined sustainability requirements. 2. Second line – Global Sustainability, together with Legal, Risk, and Compliance Management, provides methodologies, guidance, and monitoring to ensure consistency and regulatory alignment. 3. Third line – Internal Audit provides independent assurance by reviewing the effectiveness of processes and controls. This governance is supported by a set of policies, processes, and management systems that safeguard compliance, integrity, and accountability. These include binding frameworks on data protection, information security, human rights due diligence, data ethics, intel- lectual property, and the responsible use of artificial intelligence. To secure transparency and reliable performance insights, we apply standardized procedures for risk assessments, data collection, and reporting. These procedures are continuously strengthened along with

NTT DATA Business Solutions AG Sustainability Report 2024/2025 Performance Steering Sustainability 20 Our sustainability governance relies on systematic per- formance steering, with incremental improvements to ensure that global ambitions translate into measurable progress across all countries and functions. By gradually embedding sustainability into functional responsibilities and leadership incentives, we are strengthening accountability for results. Looking ahead, performance steering will increasingly rely on digital platforms and harmonized global data systems, providing a stronger foundation for transparent and reliable reporting. Evolving global integration Data-driven oversight Local accountability Scorecards and dashboards While sustainability performance is not yet fully embedded into corpo- rate steering on a par with financial and operational targets, we are working to align both. As part of this transition, global functions increas- ingly take ownership of sustainability KPIs in their domains. Standardized procedures for data collection and validation ensure comparability across business management units. Local Sustainability Leads and BU Business Partners monitor local progress and implement improve- ment measures, supported by the Global Sustainability Team. Environmental performance is tracked through standardized score- cards across business management units, creating transparency on emissions and energy use. Broader dashboards covering social and gov- ernance aspects are in development. Incentive systems Risk and compliance linkages External transparency Sustainability objectives are increasingly reflected in leadership evaluations. Our CEO’s goals include a greenhouse gas emissions reduction target, while the Balanced Scorecard currently incorporates selected sustainability indicators for managers. Sustainability performance is closely tied to risk management and compliance monitoring. Identified deviations or risks trigger corrective measures and, where necessary, review by our Internal Audit. As part of the transition to CSRD, we are strengthening the timeliness, completeness, and reliability of our sustainability data. Voluntary external assurance of selected indicators has already been applied to build credibility and prepare for future mandatory requirements.

NTT DATA Business Solutions AG Sustainability Report 2024/2025 Planet Positive 23 As an integral part of the NTT DATA Group, we are fully aligned with the Group’s commitment to achieving net- zero greenhouse gas (GHG) emissions across our entire value chain by 2040. The Group’s net-zero targets were validated and approved by the Science Based Targets initiative (SBTi) in April 2024, confirming their align- ment with the SBTi Net-Zero Standard and the 1.5°C trajectory set by the Paris Agreement. This validation reinforces our commitment to meaningful climate action and enables us to contribute effectively to a low-carbon, sustainable future. To transfer this ambition to our operations, we are devel- oping company-level transition roadmaps, using fiscal year 2023/2024 as our baseline year. This was the first year in which our sustainability reporting was extended to cover all countries and subsidiaries, supported by external limited assurance of our emissions data. In parallel, we have already begun implementing a range of decarbonization measures across our opera- tions. These include transitioning to renewable energy, enhancing energy efficiency in data centers and offices, and promoting sustainable mobility through the further electrification of our fleet and the adoption of low-emission fuels. These actions are further reinforced by the continuous enhancement of our governance structures, strategic investment in low-carbon technologies, and a commit- ment to transparency through annual reporting and third-party assurance. We view climate action not only as a compliance requirement, but as a driver for inno- vation and value creation across our entire business ecosystem. The information provided reflects our current approach to climate change mitigation and outlines the founda- tional elements of our transition plan. A more detailed and fully ESRS-aligned transition plan will be developed in close cooperation with NTT DATA Inc. Negative impacts are primarily linked to GHG emis- sions from our IT infrastructure, vehicle fleet, and business travel, as well as high energy consumption, particularly from non-renewable sources. These impacts are driven by operational needs and infrastruc- ture dependencies, and are being addressed through targeted mitigation measures. SBM-3 Material impacts, risks, and opportunities Although our finalized double materiality analysis was not ready in time for this report, we can use our initial assessments to provide a high-level description of the most significant IROs. Our indicative IROs associated with E1 – Climate Change are outlined below. These initial insights are subject to further validation with NTT DATA Inc., as we jointly transition towards CSRD-compliant reporting. Impacts Climate-related impacts for NTT DATA Business Solutions include positive and negative effects across our opera- tions and value chain. Positive impacts include ena- bling climate action through our software and services, which support emissions data management, carbon accounting, ESG reporting, and environmental intelli- gence. Internally, we contribute to climate mitigation through energy optimization, the expansion of renewa- ble energy, responsible procurement practices, and employee engagement in emission reduction activities. Risks NTT DATA Business Solutions faces climate-related risks across physical, transitional, and operational areas. Transitional risks are most material, driven by evolving regulations and the reputational conse- quences of insufficient climate action or failure to comply with new policies and legal requirements. Operational risks include rising energy needs for cooling and pressure from clients on environmental performance which may impact competitiveness and profitability. Physical risks, such as extreme weather, pose potential threats to infrastructure potentially leading to higher operational costs. Opportunities Climate change presents a broad spectrum of strategic opportunities for NTT DATA Business Solutions. In response to growing market demand and evolving client expectations, we see potential to further expand and enhance our portfolio of software and services that support both climate adaptation and mitigation. This includes sustainable IT solutions, such as carbon accounting, climate analytics, ESG reporting, and climate risk assessment tools. Strategic opportunities also include optimizing energy consumption, integrating

Furthermore, investments in carbon removal technologies and renewable energy infrastructure rep- resent a forward-looking opportunity to mitigate future costs and contribute to net-zero ambitions. Policies and Actions E1-2 Policies related to climate change mitigation and adaptation We are in the final stages of developing our environmen- tal policy, which will address climate change mitigation and adaptation. While we had planned to publish it in fiscal year 2024/2025, the timeline was extended due to necessary alignment with NTT DATA Inc. and the integra- tion of key topics, such as the DMA. As of the publication date of this report, the policy is not yet finalized due to formal internal review processes. We remain committed to its release in the near term and continue to embed climate-related considerations into our broader sustain- ability strategy and operational practices. E1-3 Actions and resources In fiscal year 2023/2024, we established our emissions baseline with full data coverage across all countries and subsidiaries. This enabled us, for the first time in fiscal year 2024/2025, to report year-on-year changes in emissions performance at the global level. Another notable development in this reporting cycle is the first-time inclusion of Scope 3 emissions, reflecting our commitment to comprehensive climate accounta- bility. We have focused on the relevant categories to our business: Purchased goods and services, capital goods, fuels and energy, business travel, and employee commuting. The methodology behind our emissions calculations is detailed in the accompanying explana- tory notes. This step provides deeper insight into the indirect environmental impacts of our operations. It also enables more effective engagement with our value chain to identify and implement emissions reduction strategies. In fiscal year 2024/2025, our decarbonization efforts focused on three core measures: enhancing energy efficiency, increasing the share of renewable electricity, and expanding the transition to electric vehicles. Key actions implemented in fiscal year 2024/2025 • Enhancing governance and data accuracy Our climate-related actions are focused on reducing GHG emissions under Scope 1 and 2, where we have the most robust data coverage and operational control. Building on our emissions analysis, we have identified and prioritized reduction measures based on their fea- sibility, impact, and implementation complexity. To ensure accountability and effective implementa- tion, we appointed a Sustainability Lead in each country to coordinate cross-departmental collabora- tion and develop local emissions reduction road- maps. We also transitioned from Excel-based data collection to an automated system using a locally

NTT DATA Business Solutions AG Sustainability Report 2024/2025 Planet Positive 25 technical details in the Solutions AG Annual Report 2024/2025. NTT DATA Business • Advancing fleet electrification We continued to transition our vehicle fleet toward lower-emission alternatives in fiscal year 2024/2025. This included the gradual replacement of internal combustion engine vehicles with electric and hybrid models, where operationally feasible. NTT DATA Busi- ness Solutions Türkiye has transitioned all L4-level manager cars to electric hybrid models. • Reducing complex data center emissions We are exploring long-term solutions for complex emissions sources in our data centers, including the adoption of low-GWP refrigerants, investment in sustainable cooling technologies, evaluation of clean fuels for emergency systems, and collaboration with third-party data center providers to align on shared decarbonization goals. These actions are being implemented in alignment with our internal annual targets and the Group’s interim milestones. Where applicable, third-party assurance is used to validate emissions data and ensure accountability. • Increasing renewable electricity use We further increased our share of renewable electricity as part of a phased transition to 100% renewable elec- tricity across all offices and data centers, with timelines aligned to regional market conditions. In fiscal year 2024/2025, 60% of the electricity we used came from renewable sources, up from 44% the previous year. Of this total, 78% was used in our data centers and 22% in our offices, including electricity used for on-site electric vehicle charging. This progress reflects our close collaboration with local sustainabil- ity contacts, including facility management experts and local sustainability leads, as well as our continued efforts to use more renewable energy technologies. • Expanding on-site photovoltaic generation In Bautzen, Germany, we launched our largest PV system to date after 11 months of planning and con- struction. With 3,150 solar panels generating up to 2 MWp, the system has the capacity to supply 33% of the electricity for our local data center, more than double the share covered by the PV system at our Bielefeld HQ. This project reduces energy costs, increases energy independence, and contributes to climate protection by feeding surplus renewable elec- tricity back into the grid. It is a strategic investment with a projected return on investment of 7 – 8 years. Calculations show that the system could supply elec- tricity to 500 single-family homes (4,000 kWh/a). Future expansion with battery storage could raise coverage to 50% of our electricity needs. Additionally, around 1,000 shrubs and trees were planted on-site, supporting local biodiversity and urban greening efforts. For further insights, please refer to the full Our new PV system in Bautzen can power around 500 single-family homes. • Improving energy efficiency We continued to enhance energy efficiency across our operations, particularly in data centers and office buildings, through targeted infrastructure upgrades and intelligent energy management systems. At the GISA data center in Halle, Germany, a subsidiary of NTT DATA Business Solutions, we implemented a waste heat recovery system that resulted in a 2.4% reduction in electricity consumption compared to the previous fiscal year, saving approximately 50,400 kWh. Importantly, the data center operated on 100% renew- able electricity in fiscal year 2024/2025, further rein- forcing our commitment to sustainable energy use.

NTT DATA Business Solutions AG Sustainability Report 2024/2025 Metrics and Targets E1-4 Targets NTT DATA Business Solutions has adopted the climate targets set by the NTT DATA Group, reflecting our full alignment with the Group’s net-zero ambition. NTT DATA Net-Zero Vision 2040 To translate this long-term ambition into actionable steps, the NTT DATA Group has established the follow- ing interim targets: • By 2030: Achieve net-zero emissions for direct and indirect emissions from data center operations. • By 2035: Extend net-zero targets to cover all facilities and fleet operations worldwide. • By 2040: Reach net-zero emissions across the entire supply chain, including Scope 1, 2, and 3 emissions. To support the implementation of these targets, we are setting internal annual targets that align with the Group’s overarching climate goals. For fiscal year 2024/ 2025, we set a target to reduce our Scope 1 and Scope 2 greenhouse gas emissions by 2% compared to our baseline year of fiscal year 2023/2024. We exceeded this target, achieving a 3.6% reduction. The key drivers behind this achievement, such as improvements in energy efficiency, increased use of renewable electric- ity, and fleet electrification, are detailed in the previous section outlining our fiscal year 2024/2025 actions. Planet Positive 26 As Scope 3 emissions reporting is being introduced for the first time in fiscal year 2024/2025, the development of annual Scope 3 targets is still in progress and will follow a detailed analysis of the initial data collection and reporting outcomes. These annual targets are reviewed at the end of each fiscal year to evaluate progress, identify areas for improvement, and refine our actions accordingly. This structured, year-on-year approach helps ensure our operations stay aligned with the Group’s interim and long-term climate objectives. Any deviations from the targets will be analyzed and explained, including con- tributing factors such as operational changes, energy sourcing, or data quality improvements.

NTT DATA Business Solutions AG Sustainability Report 2024/2025 Planet Positive 27 E1-5 Energy consumption and mix At NTT DATA Business Solutions, energy remains the most significant resource used across our operations, particularly in offices and data centers. The following table provides an overview of our total energy con- sumption and energy mix for the reporting period, including a breakdown by energy source and type. E1-5 – Energy consumption and mix in MWh Total energy consumption from fossil sources Fuels from fossil sources Diesel Fuel oil Gasoline CNG LNG Natural gas Electricity, heating, cooling, and steam from fossil sources Electricity Heating, cooling, steam Total energy consumption from nuclear sources Total energy consumption from renewable sources Fuel consumption from renewable sources Electricity, heat, steam, and cooling from renewable sources The consumption of self-generated non-fuel renewable energy Total energy consumption Share of total energy consumption % 2024/2025 Share of total energy consumption % 2023/2024 1 Change % 44,519 30,454 11,750 78 16,999 59 0 1,568 14,065 9,379 4,686 0 14,080 0 13,910 170 58,598 76% 52% 20% 0.1% 29% 0.1% 0% 3% 24% 16% 8% 0% 24% 0% 24% 0.3% 41,487 23,916 12,754 64 9,651 50 86 1,312 17,571 13,228 4,343 0 10,403 0 10,218 186 51,891 80% 46% 25% 0.1% 19% 0.1% 0.2% 3% 34% 25% 8% 0% 20% 0% 20% 0.4% 7% 27% -8% 23% 76% 18% -100% 20% -20% -29% 8% – 35% – 36% -8% 13% 1 Energy figures in MWh for both the current and previous reporting years have been calculated using updated conversion factors provided by our parent company, NTT DATA. While the underlying fuel consumption data (e.g., liters) remains unchanged, the recalculated MWh values may differ from those published in the prior-year report due to the revised conversion methodology. In fiscal year 2024/2025, our total energy consumption reached 58,598 MWh, marking a 13% increase com- pared to the previous year (51,891 MWh). This increase occurred alongside a 15% growth in business activity, indicating a relatively efficient energy performance in the context of operational expansion. The increase was primarily driven by a 27% rise in fossil fuel consumption, with gasoline usage increasing by 76%. These changes are attributed to a combination of business growth, expanded operational activities, and enhanced data granularity, which allowed for more accurate tracking and reporting of energy use. Fossil fuel energy accounted for 76% of our total energy consumption (44,519 MWh), with 52% coming from direct fuel combustion, mainly for fleet opera- tions, a small portion for office heating, and emergency power supply in data centers. The remaining 24% came from electricity, heating, cooling, and steam derived from fossil fuel sources. The rest of our total energy consumption (14,080 MWh) came from renewable sources, primarily from purchased renewable electricity. A small portion (approximately 170 MWh) was self-generated at our headquarters office in Bielefeld. Despite the overall increase in energy use, we increased our share of electricity from renewable sources to 60% (compared to 44% in the previous year), reflecting our continued decarbonization efforts across our operations.

Minor corrections were assessed for fleet energy data in the baseline year, which “had they been restated” would have resulted in a higher baseline. However, in accordance with our restatement policy, these corrections were deemed immaterial (below the restatement policy threshold of 5%) and therefore not restated. As a result, the year-on-year comparison also reflects improved data accuracy. For further details, please refer to the Restatement policy. Electricity consumption by point of use In fiscal year 2024/2025, electricity accounted for 40% of our total energy consumption (23,459 MWh), with the majority used in data centers (64%), followed by offices (31%) and fleet charging (5%). For renewable electricity in fiscal year 2024/2025, data centers accounted for 78% of total renewable electricity con- sumption, followed by 21% from offices, and less than 1% from fleet charging. This distribution highlights our focus on sourcing clean energy for high-demand areas within our operations.

NTT DATA Business Solutions AG Sustainability Report 2024/2025 Planet Positive 29 E1-6 GHG emissions Retrospective Milestones and climate strategy target years 1 The table on the right presents our global emissions, broken down into Scope 1, Scope 2, and relevant Scope 3 categories, comparing this year’s data with the previous fiscal year. In fiscal year 2024/2025, we achieved a 3.6% reduction in combined Scope 1 and Scope 2 market-based emis- sions, exceeding our internal reduction target of 2% compared to the 2023 baseline. This progress reflects both operational developments and strategic meas- ures. The slight increase in Scope 1 emissions is pri- marily due to improved data quality in fleet reporting, while the significant reduction in Scope 2 market-based emissions was driven by the expanded procurement of renewable electricity, which raised our renewable electricity share from 44% to 60%. As Scope 3 emissions are being reported for the first time in fiscal year 2024/2025, no comparative data is currently available. Where feasible and appropriate, we will explore options to retrospectively estimate Scope 3 emissions for fiscal year 2023/2024.

NTT DATA Business Solutions AG Sustainability Report 2024/2025 Planet Positive 30 Scope 1 and Scope 2 emissions by point of use In fiscal year 2024/2025, Scope 1 emissions made up 6% of our total market-based GHG emissions, largely driven by our company fleet (94% of total Scope 1). Scope 2 emissions contributed 5% to our total mar- ket-based GHG emissions, mainly from electricity use across offices, data centers, and fleet operations (87% of total Scope 2). A smaller portion of Scope 2 emissions (13%) came from heating, cooling, and steam. Scope 3 emissions per category 89% of our total market-based emissions fell under Scope 3. These emissions are not linked to specific point-of-use categories, such as offices, data centers, or fleet. The two most significant Scope 3 categories for NTT DATA Business Solutions are emissions from purchased goods and services (71%) and emissions from business travel (14%). The chart at the top right provides a breakdown of our market-based Scope 1 and Scope 2 emissions across data centers, office locations, and our vehicle fleet.

Therefore, this disclosure requirement is not relevant at this time. E1-8 Internal carbon pricing NTT DATA Business Solutions does not currently imple- ment an internal carbon pricing mechanism. Therefore, this disclosure requirement is not relevant at this time. E1-9 Anticipated financial effects from material physical and transition risks and potential climate-related opportunities This topic is planned for inclusion in future disclosures as we progress toward full CSRD-compliant reporting. Explanatory notes to our reported Scope 1, 2, 3, and total GHG emissions Accounting standard & boundary Standard: We apply the Corporate Accounting and Report- ing Standard of the Greenhouse Gas (GHG) Protocol. Data collection, analysis, estimation, and final calculations are carried out in accordance with NTT DATA Group guidelines. Boundary: The organizational boundary follows the finan- cial control approach. Scope definitions Scope 1 Emissions: Include all direct GHG emissions from sources that are owned or controlled by the company. Specifically, mobile combustion of fuels in our vehicle fleet, stationary combustion from emergency generators and on-site heating systems, and fugitive emissions from the use of refrigerants. To quantify our Scope 1 emissions, we apply DEFRA emission conversion factors. Scope 2 Emissions: Include all indirect GHG emissions from the consumption of purchased energy, including electricity, heating, cooling, and steam. We report both market-based and location-based values in accordance with GHG Protocol requirements: • Market-based approach: Accounts for the share of elec- tricity purchased from renewable energy sources, sup- ported by appropriate contractual instruments (e.g. green tariffs, PPAs). Market-based values use supplier-specific emission factors if available; otherwise, location-based factors are applied. • Location-based approach: Uses the average emissions intensity of the local electricity grid where energy con- sumption occurs. Location-based values rely on EEA, EPA, or IEA emission factors for electricity, and DEFRA emission factors for heating, cooling, and steam.

32

NTT DATA Business Solutions AG Sustainability Report 2024/2025 Planet Positive 32 Scope 3 Emissions: Include all other indirect GHG emis- sions that occur in the value chain of our company, both upstream and downstream, excluding those already accounted for in Scope 1 and 2. We currently use a spend- based approach to establish a foundational inventory across key categories, and plan to transition to more gran- ular, activity-based data and supplier-specific emissions factors. The following categories are deemed the most relevant to our business and are currently included in our Scope 3 inventory: Restatement policy Standard alignment: In collaboration with NTT DATA Inc., we have established a restatement policy that aligns with GHG Protocol requirements. Threshold: According to our policy, a restatement of histor- ical GHG emissions data is required if cumulative changes exceed a 5% materiality threshold. Restatement triggers may include: • Category 1 – Purchased Goods and Services: Emissions • Changes in company structure (e.g., acquisitions, were estimated using P&L spend data mapped to EXIOBASE activity categories, applying country-specific EXIOBASE emission factors. • Category 2 – Capital Goods: Emissions were estimated using CapEx data and EXIOBASE spend-based emission factors. • Category 3 – Fuel and Energy-Related Activities: Well-to- tank emissions were calculated based on fuel use and purchased electricity, heating, cooling, steam using DEFRA, or IEA factors. Transmission and distribution losses are determined with corresponding factors from the same sources. • Category 6 – Business Travel: Emissions were calculated based on travel expenditure by mode of transport, col- lected from travel agencies, using EXIOBASE emission factors. • Category 7 – Employee Commuting: Commuting dis- tances were collected through a survey in one region and converted to emissions using DEFRA factors. The result- ing emissions were then extrapolated to all regions/units under NTT DATA Inc. based on permanent headcount. divestments) • Methodological updates (e.g., changes in GHG accounting approaches) • Corrections due to data errors or improvements in data quality Assessment of historical data changes: All assessments are conducted annually and are fully documented to ensure transparency and consistency in our reporting practices. Fiscal year 2023/2024 review: We evaluated corrections submitted by our local data owners for our baseline year. These updates showed improved data quality and method- ological refinements. The cumulative impact of these changes was calculated at -2.6%, which is below the restatement threshold. Assurance Scope 1, Scope 2, and Scope 3 emissions are subject to limited assurance.

NTT DATA Business Solutions AG Sustainability Report 2024/2025 Planet Positive 33 Project report From Spreadsheets to Smart Solutions W hen Reem Shamia joined the Global Sustainability & Portfolio team at NTT DATA Business Solutions in 2024, one thing stood out right away: all environmental data was collected in a massive Excel sheet. Practical? To a point. Scalable? Not quite.

34

NTT DATA Business Solutions AG Sustainability Report 2024/2025 Planet Positive 34 With over 100 facilities worldwide, each maintaining its own tab, the Excel-based approach had reached its lim- its. Copy-pasting numbers, checking dots and commas, cross-verifying fuel consumption and electricity use – all by hand. Every single line. Every single cell. “This is a great opportunity to apply our core competencies to improve internal efficiency.” From Number to Action Reem Shamia ESG-reporting is more than collecting numbers – it’s about drawing conclusions and turning them into action. For example: If the analysis reveals high fuel consumption from company cars, the company can assess whether all trips are necessary, whether meet- ings could be held online, or whether alternative modes of transportation should be considered. Such insights can be gained much more efficiently with a reliable tool that facilitates collaboration and provides all stakeholders with clear and useful information. Together with colleagues from the Smart X unit in Denmark, the Global Sustainability team developed such a tool: It does not only replace the spreadsheet, but changed fundamentally how NTT DATA Business Solutions collects and manages its environmental impact. Senior Expert – Sustainability Management & Reporting NTT DATA Business Solutions From the Beginning: The Challenge of Manual Reporting Before the new tool was in charge, all the data was collected with Excel – a popular tool for a reason: It is user-friendly, flexible and quick to set up. So, like many organizations, NTT DATA Business Solutions relied on Excel for collecting the data needed for their environ- mental reporting. To do so, each of the company’s facilities had a dedi- cated tab to enter their so-called activity data: figures reflecting Scope 1 and 2 emissions, such as fuel use for company vehicles, heating energy and electricity con- sumption. A final tab aggregated the global results. But collecting and validating the data this way came with serious challenges: Did the units use dots or commas in their numbers? Did figures end up in the right cell? Were they aligned with the previous year’s numbers? “We had to review everything thoroughly – line by line and col- umn by column,” says Reem Shamia, Senior Expert – Global Sustainability at NTT DATA Business Solutions. Reem Shamia is a Senior Expert in Global Sustainability at NTT DATA Business Solutions. With over a decade of experience working in the sustainability field, she combines her background in computer engineering and a master’s degree in sustainability to effectively bridge the gap between complex technical systems and strategic climate action.

NTT DATA Business Solutions AG Sustainability Report 2024/2025 Planet Positive 35 The foundation of credible sustainability reporting is reliable data. And even though the sustainability team did the best they could, the Excel approach was time-consuming and error-prone. What’s more, the sustainability team couldn’t access the analytics directly. With a background in both sustainability and tech, Reem quickly saw what could be possible: “This is a great opportunity to apply our core competencies to improve internal efficiency.” When Tech Meets Sustainability Before the new ESG reporting tool was even a thought, the Danish unit Smart X had already developed a robust digital solution to tackle a related challenge: understanding and optimizing energy use across company buildings. This platform laid the foundation for the new, compa- ny-wide sustainability reporting tool. Emil Bekker, Manager at Smart X at NTT DATA Business Solutions in Denmark, explains the original painpoint: “Our buildings had so many systems – one for lights, one for heating, another for water usage. But nothing connected them all. Our job was to collect everything in one place.“ Their solution was the Sustainable Buildings Platform – a centralized tool that collects and manages real-time data from sensors, systems, or applications within a building or site. It provides an overview of building performance and helps local facility teams to optimize their energy use. Imagine: adjusting climate and lighting systems based on usage of space or detecting inefficiencies early. Turning a Building Platform into a Sustainability/ Environmental Reporting Tool Seeing the potential, Reem Shamia and Emil Bekker joined forces. Their goal: to build a tool that could collect, validate, and analyze environmental data in one place and more reliably than Excel ever could. They transitioned the data from the former Excel sheets to a platform that is capable of aggregating information and generating analysis reports. From there, they developed a comprehensive scorecard and an interactive dashboard that visualizes the emission data, including sources, distribution and underlying activity metrics. The team built a tool that automates critical steps, provides data insights and visualizes the environmental impact. With integrated scorecards and dashboards, it transforms raw data into intuitive, com- parable visualizations – empowering teams to track progress and make informed decisions over time. Each subsidiary still inputs its own data – but now they can see the impact. They can compare figures with previous years and explore insights at any level of detail from business unit to country to facility view. “It empowers our local sustainability teams to validate their data, identify trends and shape their emissions reduction plans accordingly,” says Reem Shamia.

Emil Bekker Manager at SmartX NTT DATA Business Solutions Tech and Sustainability Working Hand in Hand This project shows what is possible when tech and sustainability truly collaborate. The new platform is a transparent, easy to use and future-proof solution. It’s a real asset for day-to-day work and can provide strong momentum for the overall sustainability strategy. And this is only the beginning. Reem is already thinking about what the tool could tackle, too: “How can we integrate business travel data to get to emissions? How can we calculate the impact of remote working and employee commuting,“ she is wondering. More features are already on the horizon because the tool was designed to meet any sustainability manager’s practical need – and to grow with them. Emil Bekker is Manager at NTT DATA Business Solutions. He is passionate about Internet of Things (IoT) and AI, and has got hands-on experience in implementing innovative solutions for clients. fied data across all business units. They finally have the flexibility they need: detailed and dynamic reports across Scopes 1 and 2 (and potentially Scope 3). Scalable, Smart, and Green Innovation Compared to other market alternatives, the tool is rather affordable. As Emil Bekker puts it: “We basically bundled together components from Microsoft Azure in a smart way.“ On top of that, the tool includes a launch pad where reports and data can be shared. Moreover, the new tool is built to scale. While it’s devel- oped for internal use, it could also benefit companies looking to start their climate action reporting without significant upfront investment. The tool follows green software principles – meaning for example that the platform doesn’t run when nobody is using it: a consumption-based billing plan. From Data to Strategy An effective sustainability strategy requires reliable data. Only when data is clearly presented, compara- ble over time, and accessible to all stakeholders can it lead to targeted action. The new sustainability reporting tool by NTT DATA Business Solutions: • makes emissions transparent • enables real-time analysis and comparison • supports the planning of reduction measures • shows developments over time

Nevertheless, we recognize our responsibility to use resources efficiently and contribute to a circular econ- omy. Our current focus lies in managing water and waste impacts, where we are already taking steps and laying the foundation for more structured manage- ment in the future. Strategy NTT DATA Business Solutions is committed to manag- ing environmental impacts responsibly across its operations. Our approach is guided by the principles of resource efficiency, transparency, and local accounta- bility, with a focus on improving data quality, monitoring local risks, and using resources efficiently, particularly in areas such as water for cooling and the handling of electronic waste. Stakeholder views and interests Stakeholders, including clients, employees, and inves- tors, increasingly expect transparency on environmen- tal impacts, even for service-sector companies. Water is a key topic in regions facing scarcity, while waste, especially electronic waste, is gaining attention due to its environmental, regulatory, and reputational implications. By addressing these expectations through ongoing efforts and improved disclosure, we aim to respond responsibly within the scope of our operations.

38

NTT DATA Business Solutions AG Sustainability Report 2024/2025 Material impacts, risks, and opportunities Impacts Our operations influence both water and waste streams. Water is primarily used for cooling in data centers, which can contribute to local water stress, especially in regions facing scarcity. Waste impacts arise mainly from the generation of e-waste and the use of non-circular resources. Risks Water shortages and limited availability may affect our workforce and data center operations. For waste, risks include resource shortages, regulatory changes, increased management costs, and reputational impacts if waste handling is not aligned with environ- mental expectations. Opportunities We see opportunities to expand our digital solutions to support smart water management and sustainable resource use, both internally and for our clients. This includes innovations in water monitoring, optimization, and e-waste management, enabling more circular and efficient operations. Disclosure note The information in this section is not yet aligned with ESRS. Instead, disclosure is focused on providing transparency on how we manage relevant impacts, risks, and opportunities ahead of legal obligations. The results of our recently completed DMA confirm the relevance of this topic and our commitment to contin- ued ESRS alignment. Policies and Actions 38 Planet Positive Waste Although a global waste reduction strategy is not yet established, local initiatives across our subsidiaries already contribute to responsible waste handling and awareness-raising. Examples include: At present, NTT DATA Business Solutions does not yet have a comprehensive global policy framework for water and waste management. However, both topics have been included in our DMA, which will guide future priorities and reporting. In the meantime, we are taking meaningful steps, including first measures and data collection, to build a stronger foundation for systematic management. • World Cleanup Day: Subsidiaries in Germany, the Netherlands, and Malaysia actively participate in this global movement to reduce environmental pollution. • Digital Cleanup Day: We support this initiative to highlight the environmental impact of digital waste and promote responsible digital behavior. • Reverse Logistics in Brazil: Approximately 220 elec- tronic devices, including laptops, mice, batteries, and Our business unit Türkiye collaborates with NGO TURMEPA to clean local beaches. Water We conduct annual risk assessments to identify facilities located in water-stressed regions. Efficiency measures, such as water reuse in adiabatic cooling systems, are implemented in relevant data centers. In fiscal year 2024/2025, we began collecting Water Usage Efficiency (WUE) data to benchmark performance. In addition, we have improved the quality of our water data year-on-year by expanding our reporting to cover a broader range of relevant categories and ensuring comparability with previous years. This year, we also refined our allocation of water discharge, further enhancing the accuracy and transparency of our disclosures.

NTT DATA Business Solutions AG Sustainability Report 2024/2025 Planet Positive 40 The increase in reported water discharge and the significant decrease in water consumption are due to improved data quality and classification, not to changes in actual water use. Enhanced local reporting processes and refined allocation methods have resulted in a more accurate representation of our water footprint. Our business unit Malaysia engaging in cleaning a primary school field. GRI 306-3 Waste generated Outlook At present, we do not systematically collect or report waste data, as centralized processes and metrics are still being established. We plan to disclose correspond- ing data for material types of waste by 2025/2026. Given the nature of our operations, e-waste is expected to be the most relevant category for future reporting. Water management We will continue to strengthen water management by improving data quality, transparency, and local risk mit- igation. Building on our annual water risk assessment, which considers both local water scarcity and actual usage, we will refine water-related KPIs and bench- marking through the newly introduced WUE metric. Where relevant, efficiency measures such as the use of rainwater and the recycling and repurposing of water for secondary uses will be further expanded. Waste management Waste management remains a developing focus within our sustainability program. Following the results of our DMA, we will define the scope and indicators for future reporting. E-waste diversion will be prioritized, with emphasis on corporate IT devices alongside group-wide policy alignment and supplier engagement.

Together, they raise awareness, restore ecosystems, and highlight our commitment to protecting biodiver- sity despite limited direct impacts from our business operations. Local employee engagement Local teams and subsidiaries lead activities, addressing specific environmental concerns through hands-on actions. These efforts strengthen biodiversity, but also create a strong sense of connection among employees Instead of giveaways, our German development team chose to sponsor a flower meadow. Context and Relevance Although our finalized DMA was not available at the time of preparing this report, initial evaluations suggest that nature and biodiversity are currently not material topics for our operations. As a service provider, our business activities do not involve significant direct impacts on land such as deforestation or soil sealing that typically impair biodiversity and contribute to climate change. Despite its limited materiality, we recognize the broader importance of nature and biodiversity and remain committed to supporting conservation efforts through local engagement, global awareness, and innovation. Therefore, we have kept the disclosure in this section at a high level, reflecting the topic’s current relevance and our commitment to transparent reporting.

Material impacts, risks, and opportunities • Regulators and society require alignment with international frameworks, such as the EU AI Act and GDPR, especially as AI tools become more deeply embedded in business processes. Our ambition is to meet and exceed these expectations by embedding responsibility into every stage of the technology lifecycle – from the design and develop- ment of our own products to the implementation of partner platforms and operation of managed services. The solutions we deliver have the potential to shape societal outcomes. Our finalized DMA was not ready in time for the publication of this report. However, initial assessments enable us to describe the most significant impacts, risks, and opportunities. Impacts Our technology solutions shape how organizations and people process data, make decisions, and interact with digital systems. Positive impacts arise when our products and solutions improve efficiency, enable inno- vation, and create tangible social or environmental benefits. At the same time, there is a risk of negative impacts if adequate governance and oversight are not consistently applied, potentially leading to discrimi- natory biases, misinformation, privacy breaches, or excessive energy consumption. Risks NTT DATA Business Solutions is exposed to risks from a fast-changing regulatory and technological environ- ment. These include non-compliance with legislation such as the EU AI Act, GDPR, or EU Accessibility Act. Reputational and legal risks could arise from IP infringements, cybersecurity breaches, or misuse of AI. Failure to manage these risks could undermine client trust and competitive positioning. Opportunities The growing demand for responsible technology cre- ates opportunities to differentiate. By integrating sustainability and AI ethics into innovation processes and engaging in initiatives, such as the Green Software Foundation, we help clients meet compliance require- ments and net-zero ambitions. Offering transparent, fair, and sustainable solutions enables long-term growth and trust, and strengthens our own market position.

Guided by our mission, values, and the NTT DATA Group Code of Business Ethics, and as a participant in the UN Global Compact, we are committed to responsible business conduct worldwide. Stakeholder views and interests For our stakeholders, ethical and legally compliant con- duct is a fundamental expectation rather than a topic of explicit debate. Our customers, partners, and employees take integrity, transparency, and respect for the law as a given basis for doing business with NTT DATA Business Solutions. Accordingly, compliance and ethical behavior are embedded in every interaction, including with customers who entrust us with sensitive data, suppliers who adhere to our Code of Conduct, and employees who represent the company worldwide. These expectations are rarely discussed as stand-alone issues but are implicitly reflected in the high standards of trust and accountability that define our relationships. Material impacts, risks, and opportunities Impacts Our operations influence society and business environ- ments through our commitment to fair competition, human rights, and environmental responsibility in our value chain. By maintaining a culture of integrity and transparency, we minimize potential negative impacts resulting from corruption, conflicts of interest, and

Regular training and a global whistleblowing system ensure awareness and enable corrective action when needed. Risks Key risks arise from potential non-compliance with complex and evolving legal frameworks, data protec- tion, or international trade regulations. Reputational and regulatory risks are managed through our integrated Legal, Risk, and Compliance system, and through our independent Internal Audit function. Opportunities Opportunities stem from our reputation as a trusted and responsible partner. This is an essential differentia- tor in global IT markets and a prerequisite for long- term relationships with customers, employees, and investors. Governance Responsibility for lawful and compliant conduct lies with our global Legal, Risk, and Compliance depart- ment, which is supported by the compliance units in our subsidiaries. Our Chief Compliance Officer regularly reports to the Executive Board and the Global Leader- ship Team on legal, risk, and compliance topics, and provides information on risks and potential threats. The Internal Audit function supports the Chief Compliance Officer by regularly reviewing the appropriateness and effectiveness of the established compliance rules and the internal control system through risk-oriented audit plans, suggesting improvements when necessary. Policies and Actions Disclosure note Policy framework Information in this section is not yet aligned with ESRS. Although our recent DMA did not designate Ethics and Compliance as a material topic, we continue to disclose it on a voluntary basis. This chapter is aligned with the GSC and includes the selected GRI indicators as included in the Code. Our compliance framework is anchored in a set of global policies which address relevant compliance- related risks, such as corruption, bribery, and any viola- tions of antitrust and competition laws. • NTT DATA Group Code of Business Ethics: Defines ethical behavior, fairness, respect, and lawful conduct for all employees. • Supplier Code of Conduct: Covers human rights, labor, and environmental standards across the supply chain. • Policy against Corruption and Bribery: Prohibits bribery, facilitation payments, and conflicts of interest. • Anti-Trust and Competition Law Policy: Safeguards fair competition and bans collusion, market abuse, and price-fixing. • Policy for Gifts and Entertainment: Sets clear rules for accepting or offering gifts, meals, or hospitality. • Export Controls and Sanctions Policy: Ensures com- pliance with international trade laws, embargoes, and sanctions. • Fraud Prevention Policy: Establishes measures to detect, prevent, and respond to internal and external fraud. • Risk Management Policy: Outlines the framework and principles by which we identify, assess, manage, and monitor risks. • Global Legal and Compliance Program Policy: Provides the framework for compliance risk manage- ment worldwide. Further compliance-related risks include data protec- tion violations, data loss, violations of intellectual property (IP) rights, and violations of labor laws. Governance and policies related to these topics are addressed in the chapters Data Protection and Cyber- security, Responsible Technology, and Own Workforce. Political influence NTT DATA Business Solutions does not engage in political lobbying and refrains from making any donations to political parties or candidates. Our participation is lim- ited to transparent involvement in industry associations and business networks, where we contribute our exper- tise on digital transformation and sustainability.

50

NTT DATA Business Solutions AG Sustainability Report 2024/2025 Prosperity Positive 50 During the reporting period, preparations for the CSRD and the German Supply Chain Due Diligence Act (LkSG) have been integrated into the risk management frame- work. A specific topic of focus was the refinement of our supplier risk management processes and tool land- scape to meet LkSG and sustainability requirements. Performance and Outlook At present, measurement focuses on process-oriented indicators, such as training completion rates, which were successfully achieved in the reporting year. In addition, we disclose selected GRI indicators relevant to the GSC, building on last year’s disclosures and strengthening year-on-year continuity in our ethics and compliance reporting. independence and adherence to legal standards. Over- sight by the Supervisory Board and continuous reviews of our compliance and risk management systems con- firm that our business conduct remains free of undue political influence. Actions Awareness and training The basis for compliant conduct is the awareness and empowerment of employees. Our employees are trained upon hiring and then regularly on a recurring basis. Participation in training courses is recorded and monitored centrally. The target distribution rate of 100% and the participation rate of 80% were achieved in the reporting year. Any violations of rules can be reported through the company’s whistleblower system, with vio- lations followed up according to a defined procedure. GRI 102-16 Values and corporate principles Risk management The company’s risk and compliance management sys- tem is continuously being developed. It forms the basis for preventing, detecting, and sanctioning violations of laws or company policies and guidelines. It includes the analysis and assessment of compliance risks for the company, the definition of measures to avoid and reduce risks, the publishing of new or updated policies and guidelines, the introduction of control measures, and the implementation of the complaints manage- ment and whistleblowing system. Additionally, other systems and tools support compliance processes and raise awareness of compliance issues. Our corporate culture is defined by Our Way, the NTT DATA Group’s shared mission and values that guide how we work and interact. In mid-2025, Our Way was renewed to reflect changing markets, the digital trans- formation, and the company’s expanded global scale. As part of this evolution, NTT DATA Business Solutions transitioned from its previously defined “People Values” to the Group values, advancing harmonization across NTT DATA Group units and regions.

51

NTT DATA Business Solutions AG Sustainability Report 2024/2025 Prosperity Positive 51 These values are embedded through the NTT DATA Group Code of Business Ethics, mandatory training, and global communication and engagement initiatives.

Code of Business Ethics Our guideline that defines how NTT DATA and our people are expected to conduct themselves – ethically, legally, and with respect for people and society. GRI 205-1 Assessment of corruption risks At NTT DATA Business Solutions, corruption risks are assessed jointly by our Internal Audit and global Com- pliance departments within the broader scope of our regular audit program. Reviews follow a risk-oriented approach. An abstract analysis of all subsidiaries (using indicators such as the Corruption Perception Index, revenue, employee numbers, and qualitative input) is followed by comprehensive audits of higher-risk enti- ties, ensuring each is covered at least once within a five-year period. In the reporting year, 9 of 54 operating subsidiaries were assessed. This corresponds to 17%, excluding pure holdings and dormant units. In the two preceding years, the corresponding shares of operations assessed were approximately 15% and 10% respec- tively, underlining our continued implementation of a rolling, risk-based review approach. While audits are not solely dedicated to corruption, this integrated approach ensures that corruption risks are systemati- cally considered and managed across our operations. GRI 205-3 Confirmed incidents of corruption In fiscal year 2024/2025, one incident of corruption was confirmed. The case was resolved through legal pro- ceedings, with accountability established. There were no impacts on contracts or business relationships.

Data protection and cybersecurity contribute directly to our sustainability agenda by act- ing as strategic enablers of stakeholder trust, business resilience, and long-term sustainable growth. Strategy At NTT DATA Business Solutions, data protection and cybersecurity are managed as distinct but closely con- nected topics. Data protection governs the ethical and legal handling of personal data. Cybersecurity ensures the resilience of infrastructures, systems, and customer environments against vulnerabilities and threats, includ- ing malicious attacks. Both are material governance issues and part of our global compliance framework. Stakeholder views and interests Our stakeholders consistently emphasize the impor- tance of secure and trustworthy digital services: • Clients demand GDPR-compliant, secure, and resilient systems. • Employees require clear policies for secure behavior and data handling. • Regulators and society expect compliance and continuous alignment with evolving frameworks, such as GDPR and DORA.

54

NTT DATA Business Solutions AG Sustainability Report 2024/2025 Prosperity Positive 54 Risks and opportunities External factors, such as evolving data protection regulations, rising cyber threats, and growing societal expectations around digital ethics, shape our risk landscape. Non-compliance or security incidents can result in financial penalties and reputational harm. By integrating data protection and information security into our sustainability strategy, we benefit from enhanced stakeholder trust, access to privacy- sensitive markets, and innovation through privacy- enhancing technologies. By addressing these expectations transparently, we strengthen confidence, reduce risk, and create oppor- tunities for a sustainable digital transformation. Material impacts, risks, and opportunities Impacts By implementing responsible data handling practices, such as data minimization, privacy-by-design, and secure IT operations, we protect individual rights and contribute to social sustainability. These measures also reduce the environmental footprint of digital infra- structure by lowering energy consumption and data storage needs. Strong governance helps prevent nega- tive impacts, such as data breaches and loss of infor- mation integrity, further reinforcing our ethical digital conduct. Disclosure note This section is not yet aligned with ESRS. We include data protection and cybersecurity as dedicated topics due to their strategic relevance and link to upcoming disclosure requirements under the EU CSRD. Their inclusion reflects our DMA findings and supports our preparation for future ESRS compliance. Governance Our Corporate Data Protection Policy defines binding requirements for implementing privacy across all subsidiaries worldwide. Compliance is overseen by our Global Data Protection Officer (GDPO) and a global Data Protection Network. Cybersecurity is embedded in our enterprise risk management system and overseen by our global IT leadership team. Our global Chief Information Security Officer (CISO) aligns our security strategy and program across all our regions, and reports to the global Chief Information Officer (CIO). Responsibilities for both topics extend to local man- agement teams and employees, especially for early risk detection and the initiation of appropriate coun- termeasures. Regular reports to the Executive Board and Supervisory Board ensure transparency and accountability. Data protection and cybersecurity contribute directly to our sustainability agenda.

NTT DATA Business Solutions AG Sustainability Report 2024/2025 Prosperity Positive 55 Policies and Actions • Information Security Policy: Defining governance, Actions To uphold high standards of data protection, we apply the fundamental principles of lawfulness, fairness, transparency, purpose limitation, data minimization, accuracy, storage limitation, integrity, confidentiality, and accountability. These principles are embedded into our operations through safeguards that include struc- tured data classification, documented records of processing activities, mandatory privacy impact assess- ments for high-risk processing, and clearly defined data breach notification procedures. Additionally, we promote a privacy-aware culture through regular training and ensure that privacy-by-design and privacy-by-default are integral to all our systems and processes. Policy framework Our data protection framework is based on the EU GDPR as a global minimum, supplemented by other national laws, such as PIPL in China, LGPD in Brazil, and CCPA in California, USA. The framework is supported by a combination of policies, contractual safeguards, and management systems: standards, and procedures for our Information Security Management System (ISMS). • Sub-Policies: Defining specific requirements for key topics, such as access control, backups, cryptog- raphy, endpoint security, monitoring, and incident management. • Information Security Guideline: Specifying the tasks and roles of employees to maintain high security standards. • ISO/IEC 27001 Certification: Demonstrates the • Corporate Data Protection Policy: Binding robustness of our ISMS within the certified scope. • SAP Global Partner Hosting Certificate: Attesting to security standards in our managed cloud environ- ments. principles and rules for handling personal data across all subsidiaries. • Data Protection Management System (DPMS): Implemented with OneTrust software to ensure systematic monitoring and documentation. • Data Processing Agreements (DPAs): Aligned with GDPR Article 28 requirements for processors. • EU Standard Contractual Clauses: Safeguards for cross-border data transfers. • Data Protection White Paper: Providing transparency to customers and partners. Our cybersecurity framework is guided by international standards, such as ISO 27001, and closely aligned with the NTT DATA Group’s overarching information security controls. It is designed to protect both internal IT envi- ronments and the customer systems we host as part of our managed cloud services. Key elements include: All employees must complete mandatory training on data protection and information security.

56

NTT DATA Business Solutions AG Sustainability Report 2024/2025 Prosperity Positive 56 For cybersecurity, we take a defense-in-depth approach, combining network security, encryption, identity and access management, and continuous monitoring. Regular security audits with subsequent recertification continue to be implemented in our data center operations. Cyber incidents are addressed through penetration testing, vulnerability manage- ment, and business continuity and disaster recovery procedures. In line with customer needs, we also emphasize sovereign cloud offerings as secure alterna- tives where compliance prevents reliance on global hyperscalers. All employees are bound by a data secrecy commit- ment and must complete mandatory training on pri- vacy and information security. Awareness campaigns and onboarding programs ensure knowledge is refreshed regularly. Cybersecurity training focuses on phishing awareness, secure handling of credentials, and the reporting of suspicious activity. These meas- ures reinforce a shared responsibility for information security across our organization. Performance and Outlook We continue to strengthen our data protection and cybersecurity management in response to evolving regulations, emerging risks, and increasing customer expectations. These efforts reflect our commitment to proactive risk management, regulatory compliance, and continuous improvement in safeguarding personal data and information. Supplementary disclosure for data protection KPIs The following indicators are disclosed as supplemen- tary information outside the GSC framework to enhance transparency. They are monitored by our Data Protection Officer and regularly reported to our Executive Board as part of our global information and risk reporting process. KPI 2024/2025 Number of substantiated data protection complaints Number of personal data breaches reported 0 complaints received from supervisory authorities or data subjects. 0 incidents, promptly contained and reported in accordance with GDPR Article 33. Percentage of high-risk processing activities covered by privacy impact assessments 100% coverage achieved. Employee training coverage on data protection and privacy Average time to respond to data subject access requests 100% of onboarded staff completed mandatory training. 7 calendar days, well below the legal maximum of 30 days. Outlook Building on the results of our DMA, we are refining and harmonizing our KPIs and targets to enhance transpar- ency and demonstrate our progress more systemati- cally. This will include expanded metrics to capture information security and cybersecurity performance.

SBM-3 Material impacts, risks, and opportunities Although the finalized double materiality analysis was not completed in time for this report, initial assess- ments allow a high-level overview of the most relevant impacts, risks, and opportunities (IROs) related to our own workforce. These insights will be further validated with NTT DATA Inc. as we transition toward CSRD-com- pliant reporting. In this section, we disclose information about the NTT DATA Business Solutions workforce. This section aligns with ESRS S1. As we are in a transition period towards full CSRD compliance, this section demonstrates our progress towards comprehensive and transparent disclosure. We acknowledge existing data gaps and are committed to continuous improvement. Highlights • Awarded Global Top Employer 2025 • Number of employees: 16,763 • Over 90 nationalities • Gender split 32.9% female / 67.1% male • Global gender pay gap reduced by 1.19 points toward greater pay equity Strategy Our employees are at the core of our business model, driving innovation and customer value. Workforce- related topics are essential for sustainable business growth. This is reflected in our people strategy, which aims to build a skilled, motivated, and diverse work- force through continuous learning, equal opportuni- ties, and a strong commitment to well-being, engage- ment, and inclusive leadership. SBM-2 Stakeholder views and interests Our stakeholders expect us to uphold fair working conditions and responsible employment practices across our operations and value chain. • Employees place high importance on transparent communication, equal opportunities, professional development, inclusion, and a safe and respectful work environment. • Clients and business partners increasingly require transparency on social and labor practices and expect compliance with recognized standards. • Regulators and society expect credible governance, reliable data, and ongoing improvements in work- force management. These expectations inform our people strategy and shape our reporting priorities under the ESRS frame- work. We address them through our employee value proposition, which focuses on inspiring and empower- ing people to grow both personally and professionally. This is supported by targeted measures, such as lead-

NTT DATA Business Solutions AG Sustainability Report 2024/2025 People Positive 60 Impacts Our most relevant impacts relate to how we shape working conditions and the overall employee experience. Positive impacts arise from fair employment, flexible work models, well-being initiatives, diversity, and continuous learning that foster engagement and inno- vation. Potential adverse impacts may occur when high workloads, project pressure, or sedentary work contribute to stress, burnout, or reduced health. Risks Key risks concern talent attraction and retention in competitive markets. Insufficient investment in training or inadequate DEI and well-being measures may reduce engagement, increase turnover, and negatively affect productivity or reputation. Broader demographic and economic factors can further influence workforce stability and skills availability. Opportunities Strong people practices create opportunities to enhance both social and business performance. Tar- geted upskilling, inclusive leadership, and well-being programs strengthen adaptability, innovation, and employer attractiveness. This positions our workforce as a key driver of long-term growth and resilience. Policies, Processes, and Actions S1-1 Policies related to own workforce equity, and well-being for all employees. Together, these principles ensure compliance with international labor standards and reflect the NTT DATA Group’s core values. Our policies define the framework for fair, safe, and inclusive working conditions across all NTT DATA Business Solutions entities. They guide responsible conduct, uphold human rights, and promote diversity, To ensure relevance and avoid overlap with other chapters, only policies directly addressing our own workforce are included below: Policy / Guideline Workforce Topics Covered Link Code of Business Ethics Whistleblowing Policy Disciplinary Policy Defines the fundamental values that guide our actions, including principles for equal opportunity, anti-harassment, health and safety, and ethical conduct. Code of Business Ethics Sets out the global process for confidentially reporting misconduct or policy breaches, ensuring fairness, non-retaliation, and a culture of integrity.

Engagement takes place through formal participation bodies, such as works councils, as well as regular surveys, town halls, and idea-management platforms. Insights are reviewed by our People & Culture organization, informing global and local programs on health, safety, flexibility, and inclusion. This process ensures transparent communi- cation, early identification of concerns, and continuous improvement in working conditions across all entities. S1-3 Processes to remediate negative impacts and channels for own workforce to raise concerns NTT DATA Business Solutions maintains a formal whis- tleblowing and complaints procedure that enables employees and external parties to confidentially and, if desired, anonymously report potential violations of laws, internal regulations, or human rights. The system functions as an early-warning and remediation mecha- nism, ensuring that issues are addressed before they escalate. All reports are documented, promptly reviewed, and investigated by trained independent specialists under the oversight of the Legal, Risk, & Compliance depart- ment. Whistleblowers are protected from retaliation and receive timely feedback on case progress and outcomes. Where misconduct is confirmed, management decides on corrective and preventive actions. The Ethics Com- mittee may provide independent oversight to ensure fairness and transparency throughout the process. on the representation at each level. • Balanced Scorecard incentive: voluntary 2% weighting for contributions to advance women in leadership and promote gender equality.

These workers typically operate under free- lance contracts or through staffing agencies. Examples include freelance software developers, project-based consultants, and application management specialists. The following are some of the most common situations in which temporary workers are hired: • Temporary replacement for employees who are on extended leave • Provision of specialist skills based on project needs • Providing additional capacity to manage temporary peaks in workloads Contingent workers are distinct from service providers. Individuals engaged through suppliers that deliver defined services (rather than direct labor) are consid- ered part of the value chain workforce, not our own workforce as under ESRS S1.

NTT DATA Business Solutions AG Sustainability Report 2024/2025 People Positive 64 Governance relating to contingent workers The governance framework for managing contingent workers at NTT DATA Business Solutions emphasizes the strategic use of both permanent and contingent labor to maintain agility and compliance within a unified operational structure. The framework aims to ensure: • A central yet flexible governance model, balancing cost efficiencies and operational scalability • Consistent application of legal, contractual, and system-based controls • Compliance with labor law and the prevention of false self-employment, which could otherwise expose the company to liability risks or penalties Our External Workers Policy defines the global struc- tures and guidelines for contracting and managing external resources, including procedures for risk prevention and role clarity between employees and non-employee workers. Number of non-employees in headcount In the reporting year 2024/2025, NTT DATA Business Solutions contracted approximately 3,499 external (non-employee) workers, representing 17.3% of the total workforce, which covers both employees and non-employees as described above.

The materiality of this sub-topic remains under evaluation. In parallel, we recognize the importance of this topic and are working to enhance our understanding and ensure data availa- bility to enable timely and accurate disclosure should it be deemed material in the finalized assessment. S1-9 Diversity metrics Gender distribution in top management The following table presents the gender distribution within top management, combining both the ESRS S1-9 reporting definition and the company’s internal career-architecture framework. In line with ESRS S1-9 AR 71, top management is defined as one and two levels below the administrative and supervisory bodies, corresponding to the Global Leadership Team (first level) and the Global Finance Team and Managing Directors (second level).

The ESRS S1 – 9 required age categories differ slightly from the company’s internal groupings, resulting in partial data coverage when transforming existing data. Both views are presented below for transparency. Company age groups Headcount Share % ESRS age groups Headcount Under 35 years 35 to 55 years Over 55 years Not disclosed Total employees 8,140 7,065 1,558 0 48.56% Under 30 years 42.15% 30 to 50 years 9.29% Over 50 years 0% Not disclosed 16,763 100% Total employees 4,461 7,892 2,022 2,388 16,763 Share % 26.61% 47.08% 12.06% 14.25% 100% Data transformation into ESRS age groups was possible for approximately 86% of employees. The remaining 14% lacked the necessary data for exact classification. The “not disclosed” figure includes the unclassified employees. S1-10 Adequate wages At NTT DATA Business Solutions, adequate wages and secure employment are prerequisites for successful talent attraction and retention. The high proportion of knowledge workers we require and the tight labor mar- ket for IT and consulting professionals mean that local legal minimum wages are not our standard. Generally, the salaries at NTT DATA Business Solutions are com- petitive within local job markets, meaning they exceed minimum standards. Our Global Human Rights Policy formally ensures that all group companies adhere to living wage standards. This is defined as an income that enables an employee to meet their own and their family’s basic needs and maintain a decent standard of living. The policy further points to the general practice of paying competitively compared to local market standards. Risks relating to human rights, including wages, are monitored based on the requirements of the LkSG. Please also see the section Human Rights. S1-11 Social protection Disclosure under ESRS S1-11 is omitted as the materiality of this topic has not yet been conclusively determined. At the same time, we acknowledge the potential rele- vance of this topic. We are taking steps to deepen our understanding and improve data readiness to ensure we can report appropriately should it be identified as material in the final assessment.

NTT DATA Business Solutions AG Sustainability Report 2024/2025 People Positive 66 S1-12 Persons with disabilities Disclosure under ESRS S1-12 is omitted at this stage. While preliminary results from the DMA indicate that the topic will be material, we are currently facing signif- icant challenges in data collection and processing, particularly due to data privacy regulations and local legal constraints that limit the ability to store or analyze disability-related information. For example: • In Germany, the General Equal Treatment Act (AGG) and GDPR restrict the collection of sensitive personal data unless explicitly required and consented to. • In France, disability data collection is subject to CNIL guidelines, which impose strict conditions on pro- cessing health-related information. We are actively working to identify compliant approaches and improve our internal capabilities to ensure readiness for future disclosure, once materiality is confirmed and legal pathways are clarified. S1-13 Training and skills development metrics This disclosure covers performance and career devel- opment reviews, as well as training and learning activi- ties, based on data available for approximately 86% of employees. Subsidiaries not yet integrated into the central HR system are excluded; accordingly, the figures reflect only entities with system-based data availability. Performance reviews NTT DATA Business Solutions encourages all employees and managers to participate regularly in performance and career development reviews. The company pro- vides the tools and processes needed to ensure that reviews are meaningful, consistent, and supportive of professional growth. Gender Female Male Total Average hours per person 13.92 11.98 12.61 Hours 65,036 116,286 181,322 During the reporting period, approximately 78% of employees (within system coverage) participated in the review process. Gender Female Male Total Number of documented reviews 3,591 7,552 11,143 Share % 76.88% 77.82% 77.52% Training hours NTT DATA Business Solutions offers a wide range of learning opportunities through its central learning management system (LMS), and through external platforms, such as the SAP Learning Hub and the UN Global Compact Academy. A total of 181,322 training hours were recorded through the available systems. As training hours from some external platforms are not yet fully captured, the reported data represent a conservatively lower estimate of total learning activity. On average, female employees invested around two hours more in training than male employees. S1-14 Health and safety metrics NTT DATA Business Solutions is strongly committed to ensuring the health, safety, and well-being of employ- ees. These are critical issues that not only concern human lives, but also directly impact costs and produc- tivity. The preliminary results from the DMA indicate that the topic will be material. However, final conclu- sions relating to the KPI relevant to the nature of our industry are pending. Therefore, disclosure under ESRS S1-14 is partial for this reporting year. Health and safety management system Our commitment to health and safety is reflected in our Code of Business Ethics and in our Human Rights Policy Statement, both of which are applicable to all country business units and subsidiaries of NTT DATA Business Solutions. Responsibility for implementing measures relevant to health and safety in the work- place lies with our local people managers in collabora- tion with our local compliance managers. Together, they ensure adherence to laws, regulations, and guide- lines on a country level, including all applicable provi- sions for workplace health and safety.

67

NTT DATA Business Solutions AG Sustainability Report 2024/2025 People Positive 67 Rather than being covered by a single global health and safety management system, our employees are covered by country-level management systems that reflect local legal requirements. This includes the iden- tification of relevant legislation, incorporation into local policies and procedures, and monitoring of compli- ance, as well as record-keeping and documentation as required by local regulatory authorities. Work-related incidents, accidents, injuries, ill-health, and fatalities The reporting year marks the first global disclosure of occupational health and safety metrics for NTT DATA Business Solutions. We acknowledge existing data gaps and the need for further harmonization to fully meet ESRS S1-14 requirements in future reporting cycles. For this disclosure, work-related accidents or injuries include all registered incidents reported under local regulations. The consolidated figure reflects the sum of locally registered work-related accidents rather than a fully harmonized global definition. Global reporting of work-related ill-health has signifi- cant limitations. In most jurisdictions, illnesses can only be classified as work-related when a direct causal con- nection to work activity is legally confirmed. In practice, sick-leave notifications or medical certificates typically do not specify the underlying reason for absence or whether it is work-related, making reliable classifica- tion impossible in most entities. One subsidiary reported one case of work-related ill-health that was directly linked to a recorded work-related accident. No other subsidiaries reported comparable data. S1-15 Work-Life Balance metrics Reported figures on fatalities reflect only confirmed work-related cases in line with local legal definitions. In many countries, fatalities can be classified as work- related only when a direct causal link to work activity is established; consequently, all entities reported zero fatalities for the reporting period. Reported days lost represent the total number of days employees were unable to work due to work-related accidents as reported by local entities. Absences related to work-related ill-health are not yet systemati- cally captured due to local legal restrictions. Work-related accidents, fatalities, and ill health Number of recordable work-related accidents Total hours worked Rate of recordable work-related accidents Number of cases of recordable work-related ill health Number of fatalities as a result of work-related injuries and work-related ill health Days lost due to work-related injuries and fatal- ities (accidents) Number/rate 47 32,047,870 1.47 1 0 321 At present, we are not in a position to report globally on the availability and uptake of family-related leave across all our operations. While we can confirm that in Germany, where our headquarters is located, all employees are entitled to take family-related leave in accordance with national legislation, we are still in the process of assessing and harmonizing data collection practices across our international subsidiaries. We aim to establish a consistent global reporting framework in future reporting cycles. S1-16 Remuneration metrics This disclosure covers the gender pay gap as well as the total remuneration ratio, based on data available for approximately 86% of employees. Subsidiaries not yet integrated into the central HR system are excluded; the figures reflect only entities with direct sys- tem-based data availability. Gender pay gap We calculate the gender pay gap as a weighted pay gap, considering the gender distribution. It is expressed as the percentage of the average pay level of male employees. Compared to the prior year, we have been able to reduce our global weighted gender pay gap by 1.19 percentage points, towards achieving a more equitable pay for our female employees.

This ratio is often used to assess pay equity and transparency within an organization. It is defined as the ratio between the remuneration of the company’s highest-paid individual and the median remuneration for its employees. Global Annual total remuneration ratio 2024/2025 25.2 For NTT DATA Business Solutions, we have calculated a value of 25.2 at the global group level, indicating that the highest-paid individual in the company earns 25.2 times the total annual compensation of the median employee. Operating across countries with diverse eco- nomic conditions, pay structures, and workforce com- positions, the underlying data is affected by several challenges. This includes skewing due to a high share of FTE in lower-income countries, or due to executive pay being located in our headquarters, which is based in a high-income country. Explanatory notes to S1 metrics and related accounting principles Number of employees: The number of employees is counted in heads, independently of their capacity levels. Headcount is reported as of the last day of the reporting period, March 31, 2025. Gender categories: The gender category “other” refers to individuals whose gender identity does not align with the traditional categories of male or female, and who prefer to keep this not-declared. This may include non-binary, gender- queer, agender, or other self-defined identities. This category is available for consolidated data reporting across all group companies since the reporting period 2024. Employment contract types: Two types of contracts are reported that separate between permanent and temporary employees. The temporary category includes hourly-based contracts, for example, as used with working students, who have a minimum number of hours guaranteed. Leavings: This describes the total number of employees who have left NTT DATA Business Solutions during the reporting period. It includes voluntary leavings, as well as dismissals or terminations due to retirement. It does not include rehires, internal transfers, or exits due to death. It is reported as a full-year number. Employee turnover: This describes the rate of leavings. It is calculated using the total leavings as the numerator and the average headcount during the reporting period. Non-employees: This type of worker is a non-NTT DATA Business Solutions employee who is hired to provide services on a contract basis. There is no employment contract with the individual directly. Typically, contingent workers are employ- ees of another corporation or self-employed freelancers.

NTT DATA Business Solutions AG Sustainability Report 2024/2025 People Positive 69 Work-related accidents: Disclosure is based on country subsidiary data collected outside the central HR system. Each reporting entity provided the total number of recordable work-related accidents for its local employees, including inci- dents occurring on business trips, during company events or sports activities, and—where defined under local law—com- muting accidents. Definitions and thresholds for “recordable accidents” vary by jurisdiction. The consolidated figure repre- sents the sum of locally registered cases rather than a harmo- nized global definition. Days lost: Country subsidiaries reported the total number of days employees were unable to work due to work-related inju- ries. In most cases, this figure includes both full and partial days of absence, as local systems do not record absences in standardized time units. As work-related illnesses are not sys- tematically captured in most countries, the consolidated num- ber primarily represents absences related to injuries from work-related accidents. Future reporting will aim to distinguish between full and partial absences and to convert lost time into full-time-equivalent (FTE) days for greater comparability. Total hours worked: The total hours worked are not yet recorded through a central system. Instead, each reporting entity provided the total number through the same data reporting template as the recordable work-related accidents. Where no local data was reported, total hours were estimated per country subsidiary using the standard weekly working time per employee multiplied by 52 weeks and the number of FTE. (Weighted) Gender pay gap: For the calculation of the gap in pay between female and male employees, we rely on the application requirements as specified by ESRS S1 AR 98-100. As hourly pay is not applicable, we used the annual target salary (FTE in euros), comprising fixed and variable components at 100% target achievement. We disclose a weighted pay gap, adjusted for the gender distribu- tion to account for the differences in representation. Work-related ill-health: Recording practices for work-related illnesses differ across jurisdictions. In many countries, sick- leave notifications and medical certificates generally record only the duration of absence, not its underlying cause, which makes it difficult to reliably classify an illness as work-related. At the same time, many entities can only report cases that have been legally recognized as work-related, which are rare. Consequently, reporting on work-related ill-health is currently incomplete, with only isolated confirmed cases available. Fatalities: In many jurisdictions, fatalities can be recorded as work-related only when a clear and direct causal link to work activity is legally established. Where such confirmation was not possible, our entities reported zero fatalities. The consoli- dated figure represents confirmed work-related fatalities only. Annual remuneration ratio: This metric has been calculated ESRS S1 AR 101. The in line with the formula specified in remuneration data includes the annual target salary (FTE in euros), comprising fixed and variable components at 100% target achievement. For the top earners, this also includes short-term incentives with the variable portion at 100% target achievement. One-off payments are excluded. Values have not been adjusted for purchasing power differences between countries, as this seems to be common practice and allows for better comparability with what other companies report.

Recognizing the complexity of global supply chains, we continuously review and optimize our processes to identify risks and prevent human rights violations. Our goal is to monitor developments, adapt our actions accordingly, and ensure we are not directly or indirectly involved in any abuses. In regions where local laws may conflict with international stand- ards, we seek ways to uphold human rights principles responsibly. Strategy Stakeholder views and interests Our stakeholders expect us to uphold internationally recognized human rights across our operations and supply chain: • Employees emphasize fair working conditions, diversity, equity, and inclusion, and provide a safe, respectful workplace. • Clients and partners require transparency on supply chain due diligence, expecting compliance with the LkSG. • Suppliers look for clear guidance and efficient processes to meet our human rights requirements. • Regulatory authorities, such as the Federal Office for Economic Affairs and Export Control (BAFA) demand credible data and evidence of robust governance.

Material impacts, risks, and opportunities Our finalized DMA was not ready in time for the publi- cation of this report. However, initial assessments ena- ble us to outline the most significant impacts, risks, and opportunities. Impacts Our main impacts relate to ensuring fair, safe, and inclusive working conditions for our own workforce, while managing the risks of stress, discrimination, or harassment. In our supply chain, human rights may be impacted by poor labor or safety practices, and by harmful substances in raw material extraction, IT hardware production, and disposal. Through our digital solutions, we also influence human rights, such as privacy, accessibility, and fairness in AI. Risks The growing scope of human rights and sustainability regulation creates financial and operational risks, as significant resources are needed to meet new require- ments and customer expectations. Supplier violations, ranging from unsafe working conditions to the use of potentially harmful materials, and internal misconduct may disrupt operations and weaken trust with employ- ees and customers. Human rights due diligence is key to maintaining our strong employer brand. Opportunities Respecting human rights strengthens our employer brand and helps us to attract and retain talent. Trans- parent due diligence and responsible sourcing build cus- tomer confidence, while embedding human rights prin- ciples into digital solutions and supply chain practices creates opportunities for innovation and differentiation. Disclosure note The information in this section is not yet aligned with ESRS. Instead, disclosure is focused on meeting GSC requirements and providing transparency on how we manage relevant impacts, risks, and opportunities. The results of our recently completed DMA confirm the rel- evance of this topic and our commitment to continued ESRS alignment. In addition to the information available in this report, NTT DATA Business Solutions also publishes a legally required annual report on compliance with LkSG, which is available on our company website.

New roles, such as a dedicated expert for supplier risk management, have been created to strengthen implementation. A supplier management platform has been introduced to support monitoring and data collection. Risk analysis We follow an abstract and concrete risk analysis approach, both for our own business operations and for existing suppliers. 1. Abstract risk analysis – To identify general risks at a country and industry level. 2. Concrete risk analysis – To assess the actual risks at the subsidiary and supplier level. • Step 1 – Criteria-based classification of our subsidiaries and suppliers into low, medium, and high-risk categories. • Step 2 – Questionnaire-based assessment focusing on existing risk management measures, governance structures, policies, and activities. This risk analysis process is carried out at least once a year and on an ad hoc basis as required. All subsidiar- ies receive the questionnaire for a detailed analysis. Our supplier questionnaire is only applied to high-risk suppliers and selected suppliers with a medium-risk score. In the reporting period, no acute risks were identified in our own operations or among direct suppliers. Potential concerns remain in deeper levels of the sup- ply chain, where visibility is more limited. In our own operations, we need to be aware of two potential risks in particular: insufficient attention to health and safety aspects and unequal treatment in the workplace. Preventive and remedial actions We plan our preventive measures based on the results of the risk analysis, the complaints submitted via our whistleblowing system, and the results of the internal audit. We address risks proactively through: • Supplier Code of Conduct and updated compliance checks for new suppliers. • Mandatory trainings on human rights, workplace safety, diversity, and anti-harassment. • Regular awareness campaigns on global health days and mental health initiatives. When violations occur, we act immediately. For suppli- ers, corrective action plans may be agreed on and con- tracts may be suspended or terminated in cases of non-compliance. Grievance and complaints mechanisms We provide multiple accessible channels for employees, suppliers, and external stakeholders to raise concerns, including the SpeakUp platform, the Global Ethics Helpline, and local reporting lines. Complaints can be submitted anonymously in several languages. The Rules of Procedure ensure transparency on how reports are handled. Performance and Outlook In this section, we report on KPIs related to human rights across our operations and supply chain, in line with the requirements of the GSC. GRI 412-1 Human rights impact assessment in operations In the reporting year, we conducted our first full-scope human rights risk analysis in line with LkSG, covering 54 active subsidiaries. This represents 100% coverage of operational entities, excluding dormant companies and holding companies without business activities at the time of the assessment.

Based on the results, 28 of our 3,144 suppliers (0.89%) were classified as having a medium or high actual or potential risk and were asked to complete a detailed questionnaire. In seven cases, we reinforced compli- ance by sharing our Policy Statement on Human Rights and redistributing our Supplier Code of Conduct, requesting formal acknowledgement of our require- ments on human and labor rights. No business rela- tionships were terminated during the reporting period. Outlook In the coming reporting cycles, we will transition to ESRS, refining our Group-wide human rights KPIs and target setting to ensure greater consistency and comparability across the organization. GRI 406-1 Incidents of discrimination GRI 412-3 Screening of investment agreements In the reporting year, three incidents of discrimination were reported through formal grievance channels. All cases were investigated. Two incidents were resolved and closed through corrective measures, including management intervention and personal conversations about company values. One case remains under ongo- ing monitoring. In the reporting year, we conducted our first full-scope human rights risk analysis in line with LkSG. In the reporting year, two significant investment agreements were reviewed for human rights aspects, corresponding to 100% coverage. We define significant investment agreements as M&A transactions involving the acquisition of majority stakes, excluding intra- Group acquisitions. To strengthen our screening pro- cess, we extended our M&A Due Diligence Question- naire to ensure broader coverage of human rights aspects beyond strict legal compliance. GRI 414-1 Screening of new suppliers In the reporting year, all 1,928 new suppliers were screened for compliance risks, including for social and human rights aspects, ensuring 100% coverage. Compared to the prior year, we further strengthened our processes. Since June 2024, new suppliers classified as high risk are additionally required to complete a detailed questionnaire to provide deeper insights into their actual practices. GRI 414-2 Risk analysis of existing suppliers In the reporting year, we conducted a human rights risk analysis of all 1,216 active existing suppliers, in addition to screening 1,928 new suppliers. The assess- ment followed the criteria defined in LkSG, covering risks such as child and forced labor, occupational health and safety, freedom of association and collective bargaining, fair pay, non-discrimination, unlawful land

When digital humans become more than avatars, they can guide and motivate patients and relieve healthcare systems stretched to their limits. A new way to make care more accessible and sustainable.

It’s a chronic lung condition that makes it hard to breathe. For people living with COPD, something as simple as walking across a room, climbing stairs, or laughing with a friend can feel like running a marathon. Why is that? Because the lungs gradually lose their elasticity. The airways become narrow and inflamed. Over time, the sensation of not getting enough air becomes part of everyday life. COPD-patients will eventually die from the disease – if not from something else. Over one-in-three have severe depression. Many suffer from anxiety and fear leaving their homes. They seclude themselves and step back from society. Tragically, for some, the disease ends as they feared: dying alone from suffocation. Reducing Hospital Visits and Improving Quality of Life Thomas Nørmark is Director Global Head of Innovation of NTT DATA Business Solutions in Denmark. Nørmark has been working for the company since 2004. He specialises in disruptive technologies such as AI, the Internet of Things and Big Data. In response to these challenges, Denmark’s Region of Zealand launched an experiment. Over five years, COPD-patients’ breathing data was digitally monitored at home, allowing their individual treatments to be adjusted accordingly. With remarkable results: hospi- talization rates dropped by 50%. Participants reported feeling more confident, more cared for and more socially active. Seeing their own health condition on-screen and being reminded to do their exercises made a real difference in how they lived. However, most COPD patients are plus 60 years old and face barriers when it comes to using digital tools or home equipment. This meant that merely one third of the patients were able to participate in the project. That is where the idea of a digital human came in.

NTT DATA Business Solutions AG Sustainability Report 2024/2025 People Positive 77 Rasmus Gade Ørtoft is Director of UX & Design, Innovation & Technology at NTT DATA Business Solutions. He is a passionate user experi- ence expert and has been working in the Danish team since 2019. A Platform That Learns Like Newborns Seven years ago, NTT DATA Business Solutions started a research project working with robots: the project explored how to mimic human behavior in technology. Back then, Artificial Intelligence (AI) was at a very early stage, it had just started to be able to understand human language and to respond in the same way. But things have moved rapidly since then. As Thomas Nørmark, Global Director AI & Innovation at NTT DATA Business Solutions, puts it: “We tried to not only repli- cate human behavior, but also the human appearance, the look and feel of humans. And this user experience is called digital human technology.“ From this technology, the digital human emerges. And it’s about more than just language. “93% of the emo- tional communication is nonverbal. It’s not what you’re saying, but how you’re saying it, how you’re communi- cating,“ explains Thomas Nørmark. NTT DATA Business Solutions’ digital humans were trained to reflect this. The result: a digital newborn that looks and behaves like a human. The digital newborn comes with no specific skills, like a human baby. With training, it can evolve into a special- ized professional ready for implementation in a specific field. Today, NTT DATA Business Solutions’ range of dig- ital humans has receptionists, sales agents, librarians, car dealers, tourist information guides, and also: a digital human hospital assistant. We tried to not only repli- cate human behavior, but also the human appearance, the look and feel of humans. And this user experience is called digital human technology. Thomas Nørmark Global Director AI & Robotics NTT DATA Business Solutions Denmark Digital Companion for Patients When the Region of Zealand asked NTT DATA Business Solutions to support their COPD patients, Rasmus Gade Ørtoft, Director of UX & Design at NTT DATA Business Solutions, was eager to explore what a digital human could do in such a sensitive context. He saw an oppor- tunity: “We would finally be able to get direct feedback from patients on what it feels like to talk to a robot.” Together with his team, he set up a workshop and a short testing phase in which patients could interact with a digital human assistant – a stand-alone commu- nication tool that patients could use to support their treatments, in addition to the hospital’s existing moni- toring system.

78

NTT DATA Business Solutions AG Sustainability Report 2024/2025 People Positive 78 One core goal was to include the two-thirds of COPD patients who had been excluded from the original pilot due to limited digital literacy or physical impairments. In the workshop and overall survey of patients’ needs, they found out, for example, that it would have helped the patients to receive phone calls from nurses remind- ing them about their treatment steps. But hospitals don’t have capacity. That led Rasmus Gade Ørtoft and his team to wonder, “How close to that situation can we actually get with this type of technology?“. We would finally be able to get direct feedback from patients on what it feels like to talk to a robot. Rasmus Gade Ørtoft Director of UX & Design, Innovation & Technology NTT DATA Business Solutions The digital human addressed these issues. It was espe- cially helpful for patients who had poor vision or diffi- culty with motoring skills or using touchscreens. It could guide users step by step – even playing a video tutorial when someone asked, “Can you help me con- nect to Wi-Fi?” a device about things they hesitated asking a nurse – out of fear of being a burden. Rasmus found out that patients hold back a lot of questions. The digital human enables digital inclusion and thus means empower- ment. Especially for older patients with COPD, this kind of support can be life-changing. The End of a Pilot, But Not the Vision Despite its success, the project in Zealand ended due to public funding cuts. This was upsetting, particularly for the patients, but also for the team who worked pas- sionately on the project. But the work is not lost. The insights gained and the technology developed remain valuable and ready to be brought to life again. Rasmus Gade Ørtoft already envisions new possibili- ties: He sees great potential in using the digital human to support people during rehabilitation – a phase that often takes place outside of hospitals or rehab facilities. And yet, this is when patients need guidance the most. Regular exercise, timely information, and a sense of connection can make a lot of difference, both physically and mentally. A digital human could provide exactly that: reminders for exercises, step-by-step video instructions, personal- ized medication plans, and even simple check-ins that connect patients with their doctors. Patients reported that they felt relieved. They preferred using the digital human, as they did not bother asking What’s more, the potential to monitor patients remotely and track their recovery progress – without requiring them to visit a doctor or nurse – could be a game changer for any health system, too. Having access to real-time data on patients’ conditions and behavior enables more personalized care and could help prevent complications early. There is clear hope that digital human assistance will soon find a new home in healthcare: to support patients and relieve overburdened medical staff. AI in Healthcare: More Time for People What digital humans can do in healthcare – and why this is sustainable: • Easing the burden on medical staff – less stress at work due to fewer patients. • Fewer hospital visits – saving clinical resources. • Supporting patients with exercises, medication, and technological and everyday questions – higher quality of life. • Promoting digital and therefore societal inclusion – even for elderly patients with no tech skills.

This dual-impact approach reflects our belief that sustainability must empower both people and the planet. SDGs: The One Day One Tree initiative com- bines reforestation with meaningful community engagement and support. Hands-On Impact: Volunteering and In-Kind Support Our in-kind contributions and employee-driven initia- tives create tangible impact through volunteering, awareness campaigns, and local engagement. These efforts reflect our commitment to inclusive, communi- ty-centered development.

This program empowers young students to explore how technology can drive positive change, aligning with SDG 4 (Quality Education) and SDG 10 (Reduced Inequalities). Through hands-on workshops, our UK and Ireland team sparked curiosity and confidence in schoolchildren, showing how AI and robotics can solve real-world challenges. On Innovation Day, 20 students from St. Joseph’s Primary School visited our NTT DATA UK&I facilities. During the robotics workshop, they explored the practical application of AI and robotics, and shared enthusiastic feedback about their experience. By creating inclusive, engaging learning environ- ments, we aim to inspire the next generation and contribute to a more equitable future. SDGs: The children from the St. Josephs primary school in the UK proudly studied how AI and robotics can solve real problems.

In the United States, the Women’s Initiative Network connects 42 mentors and mentees across functions, fostering growth and collaboration. In Türkiye, our participation in the Million Women Mentors project connects young women with internal leaders for career guidance and inspiration. Celebrating women’s journeys is equally vital. Our International Women’s Day events brought together colleagues from Germany, Malaysia, India, Norway, Sweden, the UK and Ireland, and the United States. Highlights included the Wall of Women campaign in Bielefeld, Germany, and the She Inspires Day hosted by our subsidiary SYBIT, where successful women led workshops to strengthen self-confidence and solidarity. Together, these efforts amplify women’s voices, expand opportunities, and help shape a more inclu- sive future in tech and beyond. SDGs: Our Polish Team brings joy and distraction to hospitalized children by teaching technology skills with LEGO robots. People Positive NTT DATA Business Solutions (Türkiye, Poland) Local volunteering and community service SDGs: In Türkiye and Poland, our colleagues demonstrated how empathy and innovation can create meaningful change. Through locally driven volunteering pro- grams, employees engaged in hands-on activities that supported communities and vulnerable groups, reflecting our commitment to inclusive growth and social responsibility. In Türkiye, the creation of the One Heart Solidarity Platform enabled real-time mobilization of employee volunteers. These volunteers established libraries in seven underprivileged schools, supported NGOs through monthly charity stands, and facilitated regular visits to shelters to care for animals. By making volun- teering more accessible, the platform empowered employees to respond swiftly to community needs. In Poland, our volunteers partnered with local organ- izations to support children, women, and animal welfare. Activities included repainting and furnishing rooms in a childcare facility, teaching hospitalized children programming using LEGO robots, hosting outdoor workshops with an aeroclub, and conducting job readiness sessions for women re-entering the workforce. Volunteers also supported a dog shelter through cleaning, repairs, and adoption outreach. These initiatives align with SDG 4 (Quality Education), SDG 5 (Gender Equality), SDG 10 (Reduced Inequali- ties), SDG 15 (Life on Land), and SDG 17 (Partnerships for the Goals), showcasing how employee-led action can build stronger, more inclusive communities.
