Acerinox

The Acerinox Board of Directors is the body responsible for representing and managing the Company. This body has all the non-delegable powers established by Royal Legislative Decree 1/2010, of July 2, which approves the revised text of the Corporate Enterprises Act, as well as those established in the Regulations of the Board of Directors, including the monitoring and supervision of sustainability management at the Group, including the monitoring and execution of related policies.

In accordance with Article 19 of the Company Bylaws and Article 4.1 of the Regulations of the Board of Directors, the Board of Directors shall be comprised of a number of Directors to be determined by the General Shareholders' Meeting, between a minimum of five and a maximum of fifteen. The General Shareholders' Meeting held on April 11, 2019 set the maximum number of members of the Board of Directors should at least 40% of the total. All this has led to a progressive increase in the number of female Directors from 23.08% in 2018 to 36.4% at December 31, 2024, complying with the figure set for eleven-member Boards according to the Annex to Directive (EU) 2022/2381 of the European Parliament and of the Council of November 23, 2022 on improving the gender balance among directors of listed companies and related measures. Among the Independent Board Members, female members represent 57% of the Board.

When new vacancies have arisen, the Appointments, Remuneration and Corporate Governance Committee endeavors to ensure that the candidates include women who meet the desired profile, ensuring a non-discriminatory process with the underrepresented sex.

Pursuant to the appointments and re-elections proposed to the General Shareholders' Meeting in recent years (Ms. Rosa María García Piñeiro, Ms. Laura González Molero and Ms. Marta Martínez Alonso in 2017; Ms. Leticia Iglesias Herraiz in 2020; and Ms. Laura González Molero, Ms. Rosa María García Piñeiro and Ms. Marta Martínez Alonso in 2021), the appointment policy used by the Company demonstrates that not only are there no implicit biases that could imply any discrimination and hinder the election of female Directors, but that the Company has deliberately sought to appoint female Directors who meet the requirements of honorableness, suitability, recognized professional solvency, skill, experience, qualifications, training, availability, and commitment, which are indispensable for the proper performance of their duties.

At the behest of the Appointments, Remuneration and Corporate Governance Committee, the Board of Directors drew up and approved its own skills matrix. This document is made to serve as a mandatory guide for all Board Member selection processes and assignments to specific Committees.

In order to ensure that Directors have the necessary skills to carry out their duties properly, the Appointments, Remuneration and Corporate Governance Committee appointed the members who, in accordance with the current General Board Diversity and Director Selection Policy, meet the requirements of honorableness, suitability, recognized professional solvency, skill, experience, qualifications, training, availability, and commitment to their duties, which are indispensable for the proper performance of their duties.

The members of the Board of Directors bring together a huge range of skills, encompassing industry, sales, investment banking, and finance, as well as specialization in areas such as audit, sustainability, energy and new technologies. It is also common for directors to have previous experience on the boards of other major international companies. The criteria for assigning profiles to each Committee are similar to those of the Board.

There are no directors representing employees and other workers.

Sustainability is integrated into Corporate Governance. In this regard, various Company bodies are involved in the establishment, supervision, and management of these issues.

The Board of Directors is responsible for the Company's overall strategy. As part of this, it is responsible for overseeing sustainability-related IROs, approving the setting of targets that contribute to advancing the Group's commitment to the environment, people and society, as well as overseeing the monitoring of progress in this area. Sustainability issues are part of the decision-making process of the Board of Directors, which is regularly updated on the Group's targets and progress in these matters. For more information, see the list of material issues in Appendix 8.5. In addition, in 2024, training was provided to the Board on the contents of the CSRD and the implications at the Board level and on the Group's management and reporting.

The Sustainability Committee is the body in charge of promoting and coordinating the Company's sustainability actions in accordance with the guidelines approved by the Board of Directors, as well as proposing the adoption of any measures related to the aforementioned matters. Its duties also include implementing and monitoring the Group's Sustainability Plan, as well as reporting on this area.

The Sustainability Committee is also responsible for periodically evaluating the Group's Sustainability Policy so that it complies with its mission of promoting the corporate interest and that it considers, as appropriate, the legitimate interests of the remaining stakeholders.

The most significant activities of the Sustainability Committee in 2024 were as follows: • Monitoring of the targets defined as indicators or KPIs by the Board, the associated action plans, and the resources required to achieve them. • Monitoring of the Non-Financial Statement. • Review of ESG indicators for the calculation of senior management bonuses. • Drafting of a plan to adapt to the Corporate Sustainability Reporting Directive. • Review of sustainability policies.

The Sustainability Committee maintains direct communication with Sustainability Management, which is responsible for establishing the Group's sustainability commitment and strategy. The Sustainability Department reports, at least quarterly, on the degree of achievement of the established targets and the Company's progress on environmental matters, social impact, health and safety indicators, and aspects related to due diligence according to the initiatives implemented by the Group. This is done prior to the publication of the quarterly external reports.

The Sustainability Director is also a member of the Management Committee. This Committee is responsible for the regular review of the Company's strategy and business and investment plans, integrating sustainability into these decisions. In this way, the Sustainability Department maintains regular and direct communication with the various corporate areas that are also part of Acerinox's sustainability strategy.

The Audit Committee also acts as a supervisory mechanism in sustainability matters as it is responsible for the supervision of financial and non-financial information, as well as the Group's risk management and monitoring, which is reported on a quarterly basis. In order to ensure coordination between the two committees, the Chair of the Audit Committee is also a member of the Sustainability Committee.

The Acerinox Directors' Remuneration Policy states that the CEO's Bonus goals (variable remuneration) are linked to sustainability criteria such as safety at work, GHG emissions, diversity, and recycling. The weighting of these goals in the total computation of the bonus may not be less than 10%.

The Sustainability Committee and the Appointments, Remuneration and Corporate Governance Committee proposed that the weighting of sustainability indicators in the Acerinox Group's Senior Management variable remuneration should increase to 15% of the total by 2024 in the case of the Chief Executive Officer, the Chief Corporate Officer, the General Secretary and the Deputy Secretary General, and maintain a 10% weighting for the other members of Senior Management.

The ESG indicators used to calculate the Senior Management variable remuneration for 2024 are as follows:

a. 26% annual reduction in Total Incidents Recorded (TIR) for the Group compared with 2023, with a weighting of 50%.

b. 1.54% reduction in the Group's greenhouse gas emissions (Scope 1 and 2) compared to 2023, with a weighting of 16.6%.

c. 4.01% increase in the Group's waste recycling ratio compared to 2023 levels, with a weighting of 16.6%.

d. 0.25% increase in the number of women in the Group's workforce compared to 2023 levels, with a weighting of 16.6%.

For the CEOs of the various business units, the sustainability index is defined in the aforementioned manner, albeit with reference to the specific targets of the companies for which they are responsible.

At the beginning of FY 2025, the Sustainability Committee and the Appointments, Remuneration and Corporate Governance Committee reviewed compliance with ESG targets, which reached 59%.

The ESG indicators for calculating Senior Management bonuses are reviewed annually by the Sustainability Committee and the Appointments, Remuneration and Corporate Governance Committee, and subsequently by the Acerinox Board of Directors.

Acerinox has sustainability targets linked to environmental, social and corporate governance performance, as set out in its Sustainability Master Plan and based on international standards such as the Paris Agreement and the Sustainable Development Goals (SDGs), among others. In addition, the variable remuneration of the members of the Management Committee, including the CEO, is linked to the achievement of certain sustainability targets.

One of these targets, the reduction of CO2 emissions, is related to GHG emissions due to the Group's business model. Positive impacts on GHG Reduction are due to the implementation of measures to mitigate climate change; this comes with the risk of Loss of market share due to non-compliance with CO2 rates, Increase in costs due to non-compliance with CO2e rates and Increase in costs (CAPEX and OPEX) to meet emissions reduction targets.

Until 2023, the CO2 emissions intensity target (Scope 1 and 2) was linked to remuneration at the Stainless Steel Division. In accordance with the Sustainability Master Plan, the Company committed to reduce by 20% the intensity of Scope 1 and 2 CO2 emissions by 2030, reaching a ratio of 0.95 tCO2/metric ton compared to the 2015 value (1.20 tCO2/metric ton). Taking into account the 2023 ratio (1.07 tCO2/metric ton) and the 2030 target (0.95 tCO2/metric ton), the annual Scope 1 and 2 emissions reduction pathway has been set on a linear basis of 1.54% between 2023 and 2030.

In 2024, the reduction target for Scope 1 and 2 CO2 emissions intensity was extended to the entire Group, including the High-Performance Alloys Division. To this end, a reduction in the emissions intensity ratio of 1.54% with respect to 2023 was applied. Considering that the Group's intensity ratio was 1.088 tCO2/metric ton in 2023, the target for 2024 was 1.07 tCO2/metric ton.

The annual variable remuneration bonus is determined based on the achievement of financial and non-financial targets, such as those related to sustainability and climate change. In 2024, 15% of the CEO's bonus and 10-15% of the bonuses of the other members of Senior Management were linked to ESG targets. The CO2 emissions intensity reduction target accounts for 16.6% of the ESG targets. In 2024, the target related to climate change reached 100% compliance.

The CO2 emissions intensity ratio (Scope 1 and 2) is calculated by dividing the estimated Scope 1 and 2 emissions from the 2024 GHG Inventory by the total metric tons produced. The perimeter includes Acerinox Europa, NAS, Columbus Stainless, Bahru Stainless, VDM Metals, Roldán, and Inoxfil.

The Stainless Steel Division also has sustainable loans linked to the reduction of its carbon footprint; these are tied to a 1% annual reduction in emissions intensity (scope 1+2). The 2024 target was met as the ratio was 1.044, below the target of 1.075 tCO2eq/metric ton of production.

The due diligence approach aims to reduce the probability and exposure of the Group to risks and impacts and to seize opportunities that impact sustainable value creation. The Group takes on and promotes a series of principles that must govern its actions:

a) To understand due diligence as a continuous, dynamic process to identify and manage risks and adverse human rights and environmental impacts related to the Group's business activity and its partners in the business chain.

b) To address issues with suitable measures proportional to the severity and likelihood of the actual or potential risks and adverse effects.

c) To integrate due diligence into management systems and procedures, promoting alignment between the different internal departments.

d) To repair any actual adverse effects caused by the Company or its subsidiaries through the implementation of remediation measures proportional to the Group's degree of involvement in producing the adverse impact.

e) Collaborate with partners in the business chain to improve the effectiveness of implemented preventive or corrective action plans.

f) Establish free, accessible, and non-retaliatory complaint, participation, and consultation mechanisms for stakeholders to communicate and participate in the management of adverse effects.

g) Disclose and publicly report information on due diligence processes and measures taken to identify and manage actual or potential adverse effects, including findings and outcomes.

These principles will be taken into account in the management of IROs. They were incorporated in the development of the new Sustainability Due Diligence Policy, which was approved at the beginning of 2025; a project to establish and implement the due diligence model is now underway. This model integrates the company's existing management practices in this area. Some of the included sources of information (ethics channel, customer complaints, stakeholder consultations, etc.) have already been considered in the dual materiality analysis to identify material IROs.

Acerinox is also developing a Internal Control System over Sustainability Reporting (ICSSR) to guarantee the accuracy and integrity of the data, the availability of qualitative and quantitative indicators throughout the value chain, and the availability periods for information.

To this end, risks related to the reporting of sustainability information, which are not significant, have been identified in collaboration with the internal data owners, and a comprehensive set of internal monitoring measures will be implemented to ensure its accuracy and reliability.

The methodological approach is aligned with the three lines of defense (COSO) risk model. Key to the model is the establishment of projected roles and responsibilities to ensure and oversee compliance with the ICSSR: Board of Directors, data management and monitoring officers, internal monitoring, internal audit, etc.

The ICSSR Manual establishes the roles and responsibilities in the system's monitoring and control process, as well as regular reporting to the Audit Committee.

Listening results are reported to the Board of Directors. It was not thought necessary to change this strategy or the business model in 2024.

In the dual materiality analysis, all sustainability aspects with significant relevance for the Group were identified and evaluated. Included in the 2024 list of material impacts, risks and opportunities are those related to climate for the Company's own operations. For more information on the materiality process, see the Result of the dual materiality analysis section in the 7.1 General disclosures chapter.

The following table shows climate-related impacts, risks, and opportunities and their categorization as physical or transitional climate risks, according to the Task Force on Climate-Related Financial Disclosures (TCFD) methodology. The IPCC scenarios for physical risks were taken into account in the climate risk analysis. For transition risks, the International Energy Agency's Stated Policies Scenario (STEPS) and Sustainable Development Scenario (SDS) scenarios were evaluated.

Acerinox manages significant IROs associated with climate change mitigation and adaptation at all levels of the organization. For example, in the Sustainability Master Plan, which sets targets for the most significant climate-related IROs: energy, emissions and water use.

With respect to the last point, the Group has calculated its water footprint and is currently working on various projects to improve the efficiency of its water consumption.

In the process of reviewing and updating the decarbonization plan, no significant changes were identified in the business model or in the company's assets, demonstrating the company's resilience to climate change.

The Group's climate change management model identifies and assesses the impacts of our operations on climate change following TCFD recommendations. The Greenhouse Gas (GHG) emissions inventory, conducted annually, uses methods consistent with internationally recognized standards. The carbon footprint is certified by an external verifier.

In 2024, Acerinox reviewed its activities to determine future sources of GHG emissions. In addition to calculating the carbon footprint of the factories, an estimate was made for the service centers, warehouses and sales offices. The results concluded that these emissions are not significant, as they account for less than 2.5% of the total emissions.

Scope 3 categories not previously included in the GHG inventory were also estimated, and those that were material were reported.

In 2024, the Group's total GHG emissions (Scopes 1, 2 and 3) were 6,374,512 metric tons of CO2 equivalent, 13% higher than the previous year carbon footprint, mainly as a result of the increase of emissions associated with the acquisition of materials and ferroalloys and the consideration of new reporting categories.

Corporate risk analysis analyzes short-term climate risks. The time horizon refers to the period adopted by the company as the reference period in its financial statements. The medium-term horizon (2030) is aligned with the term of the Sustainability Master Plan and its targets, while the long-term horizon (2050) is linked to the climate neutrality targets set by the most ambitious geographical area (European Union).

Climate change impacts were identified and assessed according to the methodology described in ESRS 2 SBM-3 on climate change.

The impact of climate risk on the Group's financial statements is structured into three main areas: analysis of the recoverability of non-financial assets, determination of the useful lives of plants and equipment and credit ratings. Due to Acerinox's structure and business model, at the end of this year (short term), no material impacts related to climate change have been identified; accordingly, it is considered that there is no material impact of climate change risk that should be considered in future estimates for the calculation of cash flows.

In the medium and long term, climate risk analysis using different scenarios helped us to better understand our risks and make better decisions.

In 2025, the climate risk analysis will be updated, incorporating risks related to the value chain; Haynes International will also be included.

Physical risks

Two scenarios were selected from the Intergovernmental Panel on Climate Change (IPCC): • SSP5-RCP 8.5: High emissions scenario, with a business-as-usual perspective. It forecasts that carbon dioxide emissions levels will triple by 2075, with global temperatures rising by 4.4°C. • SSP 1-RCP 2.6: Low emissions scenario aligned with the Paris Agreement, in line with achieving net zero emissions by 2050. It forecasts global temperatures to rise and stabilize at 1.8º Celsius by the end of the century.

The difference in global emissions between RCP 8.5 and RCP 2.6 represents the implementation gap to reach the Paris Agreement's target of below 2°C.

The analysis was carried out at all the Group's factories. Site-specific climate data is extracted from each plant location for each individual climate hazard included in the CRISP platform. The analysis took into account the climate-related risks identified in the CSRD. The nine most relevant are detailed below: • Extreme heat. • Extreme cold. • River flooding. • Flooding due to extreme precipitation. • Coastal flooding. • Tropical cyclones. • Wildfires. • Rainfall-induced landslides. • Water stress and drought.

For each hazard, the platform contains a global climate indicator for the starting point and future time horizons (medium and long term).

Most physical risks take into account the duration of the risk to determine the level of criticality. The results of the climate hazards (magnitude) and degree of exposure (likelihood) are combined to calculate risk scores, which can range from 0 to 10. This allows climate hazards to be compared, determining the relative level of risk associated with each hazard.

Transition risks

The analysis was carried out using two International Energy Agency (IEA) scenarios. • Stated Policy Scenario (STEPS): provides foresight based on the latest policy measures, including energy, climate, and related industrial policies. More conservative outlook ("business as usual"), with no additional or more ambitious measures to address climate change, highlighting the risks if announced targets are not met. • Sustainable Development Scenario (SDS): aligned with the Paris Agreement, this scenario assumes that all national climate and energy sector-related targets announced by governments are met in full and on schedule.

The global emissions gap between STEPS and the SDGs represents the implementation gap that must be closed for governments to achieve their announced decarbonization targets.

Transition risks have been assessed for the Company's assets in five geographical blocks: European Union, United States, Africa, Southeast Asia, and global.

The transition risk assessment includes seven climate scenario indicators that describe the risks and opportunities associated with the transition to a low-carbon economy: • Risk: Carbon mechanisms and carbon taxes. • Risk: More stringent environmental regulations. • Risk: Changes in consumer preferences. • Risk: Transition to low-carbon technologies. • Opportunity: Increased demand for low-carbon products. • Opportunity: Energy efficiency. • Opportunity: Use of renewable or low-carbon energy.

Each indicator scores each location by combining the relevance weighting with the difference between the scenarios over the time horizons, also known as the "scenario delta." The higher the delta, the greater the difference between the scenarios and, consequently, the greater the risk. Thresholds denote high, moderate, and low risk, as well as high, moderate, and low opportunities.

The results show that transition risks are more significant for some assets depending on their location. However, no assets have been identified that are incompatible with a transition to a climate-neutral economy.

In 2020, Acerinox committed to decarbonizing its activity by implementing its Sustainability Master Plan Positive Impact 360º. One of its pillars is eco-efficiency and climate change mitigation. The Master Plan set the target of a 20% reduction in GHG emissions intensity (Scope 1 and 2) by 2030, using 2015 as the base year for the Stainless Steel Division. This was extended to the entire Group in 2024.

Among the initiatives implemented by the Group's entities to fulfill this commitment are the improvement of energy efficiency, the promotion of heat recovery systems, the electrification of systems and vehicle fleets, and the increased use of renewable energies.

In 2024, it took a further step in the transition to climate change mitigation with the creation of a Decarbonization Plan through 2030 that integrates existing and new initiatives to drive the decarbonization of operations and the value chain. It also integrates the decarbonization initiatives included in the new Beyond Excellence 2024-2026 efficiency plan, approved by the Board of Directors in 2023. The 2025-2030 Decarbonization Plan has the following pillars:

• Improvement of energy efficiency: the adoption of new technologies or machinery that allow better management of process times and more efficient management of consumption.

• Promotion of heat recovery systems from process sources: installation of recovery systems that optimize processes and allow the reuse of the heat generated at the exit of furnaces or boilers. The aim is to increase the efficiency of the recovery process and generate more steam, thus avoiding its production in gas boilers.

• Electrification of systems: replacement of machinery or boilers that use fossil fuels with others that use electricity (e.g. heat pumps).

• Electrification of the vehicle fleet: replacement of the fossil fuel fleet (company cars, vans, forklifts, etc.) with electric vehicles.

• Increased use of renewable energies and, in particular, renewable electricity: signing of green energy purchase contracts with guarantee of origin (GoO), purchase of renewable energy certificates and installation of solar panels for self-supply.

• Use of low-carbon alternative fuels: use of alternative fuels in the production process (e.g. hydrogen/natural gas mix in boilers, use of biomethane, etc.).

• Increased use of scrap: installation or expansion of scrap recovery plants, improved segregation and use of scrap.

• Increased use of low-carbon raw materials or ferroalloys: prioritization of suppliers and purchase of low-carbon raw materials or ferroalloys.

• Others.

The Decarbonization Plan has a bottom-up approach, as it is designed in collaboration with each factory's technical teams and CEOs in alignment with the factory's strategy. It is also aligned with Beyond Excellence 2024-2026, the Group's strategic plan to drive competitiveness across the board.

The Decarbonization Plan does not include climate change adaptation measures. The climate risk analysis will be updated in 2025, and an adaptation plan will be developed based on the results achieved.

The Plan and the proposed emissions reduction targets for each of the factories and at the Group level were presented to the CEOs of the factories and the Group's Chief Executive Officer. They were subsequently approved by the Board of Directors, at the proposal of the Sustainability Committee, in January 2025. The targets will be monitored regularly after approval. At least quarterly, the Sustainability Director reports to the Sustainability Committee on target evaluation.

The Decarbonization Plan sets more ambitious Scopes 1 and 2 emissions reduction targets, with the aim of being compatible with limiting global warming to 1.5°C and aligned with science-based targets (SBTi): Acerinox must reduce Scope 1 and 2 emissions by 45.28% by 2030 compared to 2021. It also sets a Scope 3 emissions reduction target of 15% for the same year. Acerinox is not excluded from the EU benchmarks harmonized with the Paris Agreement.

Climate change is one of the greatest environmental, social, and economic challenges. The Group believes that mitigation should be integral to every activity and decision, knowing that this goal can be achieved without sacrificing excellence, profitability, efficiency, and returns for all stakeholders.

This commitment is embodied in the General Sustainability Policy and the Climate Change Policy, presented to the Sustainability Committee in October 2024 and approved by the Board of Directors in February 2025.

The General Sustainability Policy establishes the principles that should govern the Acerinox Group's strategy and guidelines for managing sustainability incidents, risks and opportunities, including mitigation and adaptation to climate change.

The Group takes on and promotes a series of principles that must govern its actions. These include, among others, mitigating climate change by implementing energy-efficiency measures, promoting the use of renewable energies, and optimizing water consumption, as well as adapting to the effects of climate change where appropriate.

The General Sustainability Policy also addresses the promotion of the circular economy and the rational and sustainable use of natural resources, as well as the protection and recovery of biodiversity and ecosystems.

The Group's Climate Change Policy establishes a framework for its business model and strategy to be consistent with its commitment to the transition to a low-carbon economy and limiting global warming.

The purpose of the Acerinox Group's Climate Change Policy is rooted in its General Sustainability Policy, the Sustainability Due Diligence Policy, the Group's Human Rights Policy, the Sustainable Development Goals, and the United Nations Global Compact Principles, among others.

Policies are developed in specific action plans, such as the Beyond Excellence Plan, Decarbonization Plan, and so on.

Both policies apply to all entities within the Group, which will ensure that the principles of these policies are also adopted by other business partners in the activity chain. The Board of Directors oversees compliance with both policies, and they will be available on the Company website.

In 2024, more than 50 decarbonization initiatives were carried out, saving more than 450,000 tCO2. The main decarbonization lever was the increased use of renewable energies, which in 2024 accounted for 44.45% of the Group's electricity consumption, having increased by almost 10%. Also noteworthy are the energy efficiency measures and the increased use of scrap.

Each of the actions has an associated budget (CAPEX or OPEX) that must be approved by the CEO of the corresponding factory. The table below reports the emissions avoided in 2024. Based on the financial data, an estimate has been made to allocate CAPEX or OPEX to energy efficiency (EUR 1,402,478 and EUR 216,933 respectively) and to the other decarbonization levers (EUR 635,600 and EUR 27,910,939 respectively). The Group is currently working to improve the granularity of the financial information associated with climate change actions.

The 2025-2030 Decarbonization Plan requires an estimated annual investment of EUR 817,500 in CAPEX and EUR 1,711,315 in OPEX. 95% of the CAPEX and 49% of the OPEX of the 2024 decarbonization initiatives is aligned with the Taxonomy (Acerinox Europa, Columbus Stainless and NAS). It is estimated that, in the future, the Company will have an aligned CAPEX and OPEX percentage in a similar range to that of 2024, taking into account the uncertainty that exists in this estimate.

The table includes own and upstream decarbonization measures for Acerinox Europa, NAS, Columbus Stainless, VDM Metals, Roldán, and Inoxfil. Haynes International's initiatives will be integrated into the 2025-2030 Decarbonization Plan. Specific targets and actions for climate change adaptation are expected to be added in the coming years.

The Decarbonization Plan has adopted a conservative approach, and only feasible technologies that are available today have been taken into account in the emissions reduction estimates. This mitigates the potential risk of not meeting the approved emissions reduction targets.

To carry out the initiatives, in addition to internal financing, Acerinox has sustainable credits linked to the fulfillment of decarbonization targets.

For one, the Group has a sustainable credit linked to the increase in renewable energy sources. The Company committed to improving the renewable electricity intensity ratio of the entire Group (Stainless Steel and High-Performance Alloys Divisions) by 4% per year from 2020. In 2024, this target was 273 renewable Kwh/metric tons of steel; the actual figure was 578 renewable Kwh/metric tons of steel, reaching the target. In 2024, renewable energy accounts for 44.45% of the Group's electricity consumption.

For another, the Stainless Steel Division signed credits linked to a 1% annual reduction in emissions intensity (Scope 1+2). The 2024 target was met as the ratio was 1.044, below the target of 1.075 tCO2eq/metric ton of production.

Stainless steel is a very sustainable, long-lasting, and infinitely recyclable material. Despite these positive qualities, its manufacture accounts for a considerable proportion of global industrial emissions due to the intensive use of electrical energy to melt scrap and ferroalloys, as well as the use of fossil fuels, such as natural gas, in the heating and smelting processes. In addition, the production of stainless steel and high-performance alloys requires the use of ferroalloys and other raw materials, and their availability is crucial to the Group.

One of the pillars of the Sustainability Master Plan is eco-efficiency and climate change mitigation, which sets a target of a 7.5% reduction in energy intensity, a 20% reduction in GHG emissions intensity (Scopes 1 and 2) and a 20% reduction in water withdrawal intensity by 2030, based on 2015.

In relation to the emissions reduction target, the 2025-2030 Decarbonization Plan establishes new, more ambitious targets, aiming to be compatible with limiting global warming to 1.5ºC, and based on science (SBTi). According to this methodology, Acerinox must reduce Scope 1 and 2 emissions by 45.28% by 2030 compared to 2021. A Scope 3 emissions reduction target of 15% for 2030 compared to 2021 has also been set.

2021 has been selected as the base year because it is the first year in which the GHG Inventory of the entire Group, including VDM Metals, was calculated and verified by an external party, as per the GHG protocol. Due to the sale of Bahru Stainless in 2024 and given that the inventory was conducted at the factory level, the recalculation involved the accurate subtraction of emissions associated with Bahru Stainless operations. Acerinox Group emissions in 2021, excluding Bahru Stainless, were 3,117,325 tCO2e Scope 1 and 2 and 4,877,793 tCO2e Scope 3.

In 2025, Haynes International will be integrated into the perimeter of the Decarbonization Plan and its associated targets.

The established emissions reduction targets include the operational approach and the same GHG gases that are included in the GHG inventory. The market-based approach is also used for Scope 2 emissions. The target for 2030 is 1,705,705 tCO2e of Scope 1 and 2 emissions and 4,146,124 tCO2e of Scope 3 emissions.

Prior to the approval of the decarbonization targets, the Company examined two scenarios: the baseline scenario and the achievable sustainable scenario (that aims to be compatible with limiting global warming to 1.5ºC).

First, a baseline scenario in which production remains constant between 2025 and 2030 at 2023 values while the measures included in the Decarbonization Plan are implemented. Under this scenario, the use of renewable energy will not increase in the future.

Second, the achievable sustainable scenario, in which production increases according to internal forecasts in 2030 compared to 2023 and 60% of electricity comes from renewable sources.

Depending on the production level and starting point of each factory, internal goals are established for each premise, with targets for each factory. The individual targets ensure compliance with the group-level target for Scopes 1 and 2. In addition, the overall target is also set in terms of intensity.

Similarly, Scope 3 emissions reduction targets are set at the factory level, both in absolute and relative terms. Under this scenario, the 15% reduction target in Scope 3 emissions by 2030 compared to 2021 is also achieved.

The Decarbonization Plan includes the adoption of new technologies that cannot currently be implemented due to their level of maturity, such as the use of biofuels.

Some studies and pilot projects on hydrogen injection into the natural gas grid were carried out in different factories in Europe, and the biomethane market is being assessed.

Some of these projects are expected to be completed by the end of the plan period.

According to applicable policies, the definition of the energy, emissions and blue water footprint targets was set based on estimated production capacity and industry benchmarks, Stakeholder participation was not considered.

The Sustainability Committee reviews the progress the indicators of energy intensity, emissions intensity and water footprint intensity intensity against the target quarterly, evaluating at the group, division, and factory levels. If significant discrepancies arise, the Head of Sustainability consults with factory managers and presents explanations for these discrepancies to the Sustainability Committee.

The targets established in terms of energy, GHG emissions and water withdrawal are in response to the climate risk analysis conducted in 2023 according to the TCFD methodology. The assessment showed significant transition risks related to carbon taxation mechanisms and significant physical risks related to water stress at the Acerinox Europa and Columbus Stainless factories.

Our targets for 2030

These targets are monitored monthly by the sustainability managers at each factory and later reviewed by the corporate sustainability team. Likewise, changes are assessed on a quarterly basis by the Sustainability Committee, which subsequently reports to the Board of Directors. In each case, the necessary measures are taken.

The annual variable remuneration of the Group's main senior managers is linked to the achievement of these targets, which are being deployed in the different organizational areas.

*This target was initially set for the Stainless Steel Division, but was extended to the entire Group in 2024. **Increase in the percentage of women on staff compared to the previous year, excluding the Haynes staff as it was not part of the scope when the targets were defined.

The targets linked to variable remuneration for 2025, in line with the target's review carried out and compatible with the 2030 Group roadmap, are as follows:

*Increase in the percentage of women on staff compared to the previous year.

Energy consumption and mix

Scope and methodology

Acerinox reports energy consumption for its production network. In 2024, the perimeter includes 15 factories: five stainless steel factories (three integrated: Acerinox Europa, NAS, Columbus Stainless; two long product: Roldán, Inoxfil) and ten high-performance alloys factories (seven VDM Metals, three Haynes International). Bahru Stainless was sold in May 2024 and is excluded from year-end figures; its emissions and consumption up to sale are included in inventory totals where stated.

Energy consumption is sourced from primary data (invoices) reported by facility managers. Where primary data is unavailable, secondary data (internal control records) is used. Net calorific value is established based on validated and updated sources according to facility location. Conversion factors are applied where necessary.

The 2024 energy consumption was 9.37% lower than 2023, primarily due to a ~10% decrease in melting shop production (12% including factories without melting shop).

Energy consumption and mix (MWh)

*Renewable electricity from the energy mix refers to the percentage of renewable energy from the remaining energy mix, excepting Columbus Stainless, VDM Metals USA, and Bahru Stainless from the supplier's energy mix.

**Acerinox does not produce its own energy.

***Acerinox does not consume hydrogen as fuel.

Supplementary consumption data by fuel type (MWh)

*Note: Total consumption in this table (5,173,558 MWh for 2024) differs slightly from the total in the primary energy mix table (5,166,010.67 MWh) due to different consolidation scope or rounding.

Energy intensity

Energy intensity per net revenue (MWh per EUR thousand):

Net income from activities in high-climate-impact sectors: EUR 6,607,978 thousand (2023), EUR 5,413,128 thousand (2024). Acerinox Group net income is included in the Net Revenue figure of the Profit and Loss Statement of the financial statements.

Energy intensity per tonne of steel produced:

The Group reports an energy intensity of 10.19 GJ/metric tonne of steel produced in 2024 (2023: 9.9 GJ/t). The worsening indicator is attributed to a ~10% drop in melting shop production due to the Acerinox Europa strike, Bahru Stainless closure, and macroeconomic factors. The Group has a 2030 target of 7.5% reduction in energy intensity compared to 2015 (initially for Stainless Steel Division, extended to entire Group in 2024).

Renewable energy

In 2024, renewable energy accounted for 44.45% of the Group's electricity consumption (up almost 10 percentage points from 2023). Acerinox purchased 962,202 MWh of electricity through guarantees of origin or renewable energy certificates.

The Group has a sustainable credit linked to increasing renewable electricity intensity by 4% annually from 2020. The 2024 target was 273 renewable kWh/metric tonne of steel; actual performance was 578 renewable kWh/metric tonne, exceeding the target.

Taxonomy alignment

In 2024, prior to approval of the 2025-2030 Decarbonization Plan, the Group allocated EUR 28,127,871 in OPEX to decarbonization (95% associated to Taxonomy activities), of which 1% corresponded to energy efficiency and 99% to all other decarbonization levers. CAPEX totaled EUR 2,038,078 (49% Taxonomy-aligned), of which 69% was energy efficiency and 31% other levers.

Key performance indicators (CAPEX and OPEX) for Taxonomy-eligible activities at Acerinox Europa, NAS, and Columbus Stainless were EUR 164,512,879 (CAPEX) and EUR 57,235,954 (OPEX) in 2024.

Sources and verification

Activity data for energy consumption follows the hierarchy: primary (measured/invoiced) > secondary (internal records) > estimated. Emission factors are sourced from official databases (IPCC, DEFRA UK, Spanish Ministry for Ecological Transition, Ecoinvent v3.10, supplier-specific factors, etc.).

The measurement has not been verified by an independent external body beyond the verification provider. However, the environmental management system is certified under ISO 14001.

Gross Scopes 1, 2, 3 and Total GHG emissions

Reporting basis

Acerinox calculates its GHG inventory following the GHG Protocol Corporate Standard and the GHG Protocol Corporate Value Chain (Scope 3) Standard. The consolidation approach changed in 2024 to operational control to align with CSRD requirements. The baseline year is 2021, the first year the entire Group (including VDM Metals) inventory was calculated and externally verified.

Greenhouse gases included: CO₂, CH₄, N₂O, HFCs, PFCs, SF₆. Global warming potentials are from the IPCC Sixth Assessment Report (AR6, 100-year time horizon). No biogenic emissions are generated.

The 2024 inventory covers 13 factories (Acerinox Europa, NAS, Columbus Stainless, VDM Metals, Roldán, Inoxfil; Bahru Stainless sold in May 2024; Haynes International acquired in 2024 but not included in 2024 GHG data). Service centres, warehouses and sales offices account for <2.5% of emissions and are excluded as immaterial. Bahru Stainless emissions for 2024 prior to sale: 78,961 tCO₂eq; its 2023 emissions (378,214 tCO₂eq) also excluded from 2023 comparative figures shown.

Phase-in and future scope

Acerinox is using the ESRS 1 Appendix C phase-in for anticipated financial effects (E1-9). Climate risk analysis (TCFD-aligned) updated in 2025 to incorporate value chain risks and Haynes International. Scope 3 categories to remain under review; materiality reassessed annually.

The Acerinox Group did not develop any GHG removals and GHG mitigation projects financed through carbon credits. The Company is exploring the possibility of CO2 capture, storage, and use projects. Currently, some projects are in a preliminary phase. For example, a implementation feasibility study has been conducted at one of the factories.

On the other hand, Company has not contributed to greenhouse gas sequestration projects upstream and downstream in our value chain.

The Acerinox Group has set an internal carbon price of EUR 63.75/tCO2 in 2024. The internal carbon pricing system is a shadow price, i.e., a theoretical price based on external resources. It is based on estimated changes to the carbon price in the European Emissions Trading Scheme (Carbon Pulse EUA Price Forecast, which takes into account the forecast of twelve traders). This price applies to the entire company: it is a single price, regardless of location, business unit, or activity.

Acerinox projected its carbon price according to information from the report, last updated in April 2024. The result was the following:

• 63.75 /tCO2 in 2024 • 75.30 /tCO2 in 2025 • 91.35 /tCO2 in 2026 • 109.30 /tCO2 in 2027 • 123.85 /tCO2 in 2028 • 128.45 /tCO2 in 2029 • 134.85 /tCO2 in 2030

This forecast predicts that the price of carbon will increase by 111% over the next 7 years.

The internal carbon price is applied to Scope 1 and Scope 2 in the economic analysis of energy efficiency and other decarbonization initiatives in order to incorporate this variable into investment decisions.

The Financial Statements do not take into account the carbon price.

Anticipated financial effects from material physical and transition risks and potential climate-related opportunities

Phase-in Exemption

The Group is also working to better quantify anticipated financial impacts of climate risks and is taking advantage of the phase-in period under ESRS 1-10 regarding the timeline for reporting this quantification in future years.

Responsible water management is crucial for the Group, given that producing stainless steel and high-performance alloys requires substantial amounts of this natural resource.

In 2025, the Group updated the Sustainability and Safety, Health, and Environment Policies, replacing the previous ones. The rational and sustainable use of water, along with ecosystem protection across all activities, are key principles in the Sustainability Policy, as well as in IRO management.

Similarly, the Health, Safety and Environment Policy is dedicated to protecting nature, which includes managing and consuming water resources responsibly and maintaining their quality. These policies apply to all entities within the Acerinox Group, including those in water-stressed areas. They must ensure that policy principles are followed by all commercial partners involved in the activity chain.

The Board of Directors oversees compliance with both policies, and they will be available on the Company website.

Most factories source their water from rivers (NAS, Roldán, and VDM Metals). However, some facilities draw water from swamps (Acerinox Europa), reservoirs (Columbus Stainless and Bahru Stainless), or the public supply network (Inoxfil and VDM Metals). No factory sources its water from marine resources, whether biological or non-biological.

Water is essential throughout the production process for cooling machinery and molten steel, cleaning equipment, generating steam, and treating wastewater.

Our factories have measures in place to prevent, avoid and act in the event of spills or discharges resulting from the storage of other substances. Neutralization and treatment facilities for both acidic and basic water, along with emergency ponds, allow us to maximize the recirculation of water and prevent any discharges into the natural environment. Together with other security measures, they eliminate the risk of spills. The tanks are equipped with a permanent secondary containment mechanism, as well as cleaning and emergency shutdown services.

The Group's operations have a minimal impact on marine resources since only Acerinox Europa discharges water into the sea. Water is discharged into the Bay of Algeciras through a general collector managed by the Major Industries Association of Campo de Gibraltar. This discharge is subject to regular analysis in accordance with the Plan for the Monitoring and Control of the Receiving Environment for Discharges into the Bay of Algeciras.

Note: Resources allocated to water resource management are detailed in Note 9 (Property, plant and equipment - Environment) in the Consolidated Annual Accounts.

Targets related to water

Acerinox has established water withdrawal intensity reduction targets as part of its Sustainability Master Plan under the eco-efficiency and climate change mitigation pillar.

Target 1: Water withdrawal intensity reduction (original target - achieved)

Target 2: Blue water footprint intensity reduction (new target from 2025)

Note on water consumption targets: As stated in the disclosure, "there is no defined target for reducing water consumption" - targets are focused on water withdrawal intensity and blue water footprint intensity only.

Note on marine resources: The Acerinox Group does not rely on marine resources and has not set any targets related to them.

Water consumption

Acerinox monitors water withdrawal and discharge volumes daily through flow meters, verified annually by third parties. The Group uses various water sources certified by suppliers: surface water (primary), production water, and third-party municipal water. All discharges are regularly tested for compliance with Emission Limit Values (ELVs) and legal requirements. All factories have treatment and neutralization plants to stabilize and remove contaminants before discharge, plus secondary containment systems to prevent accidental spills.

Water consumption by area and division

Note: Acerinox does not store water. The Group is investing in and developing methods to gather accurate data on recirculated water at each factory.

Water consumption in 2024 decreased by -35.34% compared to 2023 due to decreased production (around 10% in melting shop production, 12% including factories without melting shop) and water saving plans implemented at the factories. The stainless steel division's water consumption in water-stressed areas decreased by -35.17% due to the strike at Acerinox Europa. Water consumption in non-stressed areas (-70.59%) decreased significantly due to improvements in water reservoir management, better control of cooling towers, and repairs to valves and water pumps to remedy leaks.

Water intensity

Note: Acerinox Group net income is included in the Net Revenue figure of the Profit and Loss Statement of the financial statements.
