Nexa follows a structured process for hazard identification, risk assessment, and risk control, based on the corporate risk management standard (PG-SUS-SUS-013), which is aligned with ISO 31000, ISO 14001, and ISO 45001. Risk management is applied in layers across all operations, following the continuous improvement cycle (PDCA), with critical analyses, audits, and incident learning supporting decision-making. Operational tools such as APR (Preliminary Risk Analysis) in Brazil and Continuous IPERC in Peru are used in a participatory manner before and during activities, enabling the identification and control of risks in real time. For critical activities, formal permits such as PPT (Permit to Work) and PETAR are applied, ensuring prior assessment and authorization of safety conditions. Workers actively participate in risk management through tools such as Fale Fácil, Right to Refuse, and ORT (Observation of Risks at Work), which allow them to report unsafe conditions, halt activities involving serious risk, and reinforce safe behaviors, without fear of reprisal. The company also promotes training, risk perception workshops, and continuous assessments of working conditions, including specific forms for critical environments, such as underground mines. All incidents are recorded, investigated, and addressed through formal processes, with the definition of corrective and preventive actions and the dissemination of organizational learnings, reinforcing a culture of prevention and the continuous improvement of health and safety performance.

Nexa provides occupational health services through qualified multidisciplinary teams, in compliance with current legislation in Brazil and Peru and in line with international standards. In Brazil, these services are integrated into the Risk Management Program (PGR), in accordance with NR-1, and are implemented at all facilities. Access for workers is facilitated through on-site care at their workplaces, logistical support for travel to clinics, and clear communication about available services. The effectiveness of these initiatives is monitored through key performance indicators (KPIs) and reinforced by ongoing health awareness and promotion campaigns. The confidentiality of health information is ensured through the Apollus management system, with access restricted to healthcare professionals, the use of encryption, and the adoption of security protocols. Nexa complies with the General Data Protection Law (LGPD) in Brazil and Law No. 29733 in Peru, ensuring that data is used exclusively for medical and preventive purposes. Internal privacy policies, segregation of duties, monitoring, and audits ensure that this information is not used for any type of favorable or unfavorable treatment, promoting transparency, ethics, and trust among employees.

In addition to complying with regulations, we are concerned with developing a mentality of mutual care and knowledge of the real risks and mitigations within the context of our operations. To provide this learning experience, we use several methodologies for normative training: based on the 6Ds, we use online, face-to-face, hands-on training, Lego Serius Play methodology, VR and VA. In addition to normative training, there are also communication, participation and consultation programs, including:

• Nexa Safety Day: with the motto Zero Harm, the event promotes a culture in the sense of not generating damages, injuries, losses and impacts on the lives of employees.
• Sipat & Sipatmin: a Semana Interna de Prevenção de Acidentes de Trabalho promoveu diversas atividades, webinars e eventos voltados à conscientização de colaboradores próprios e prestadores de serviços sobre a prevenção de acidentes e doenças ocupacionais, estendendo o foco de atenção às famílias
• ORW (Observation of Risks at Work): this safe behavior program seeks to identify and control the risks of activities in the present, so that it is possible to reduce undesirable consequences in the future. The ORT tool is used to assess safe behaviors during the execution of activities, improving the practice of safe behavior.

We strongly believe that by refining our management system tools and implementing effective risk management, we will achieve a level of safety maturity that meets regulatory standards by 2030 and fulfill our three strategic objectives: eliminating fatal accidents; reducing the frequency and severity of personal injuries; and fostering a culture of effective risk management. In total, we trained 12,918 people and provided 56,394 hours of training in 2025 on the topic of safety.

Since 2022, Nexa has maintained and continuously improved a robust risk management system for its operational activities, structured according to the G-MIRM (Global Mining Industry Risk Management) methodology developed by the University of Queensland in Australia, with the aim of fostering a strong culture of risk-based decision-making. More than 4,000 employees and 6,000 permanent contractors have already been trained to identify, assess, and manage risks associated with processes, changes, and new projects, as well as routine and non-routine activities and service fronts, applying these concepts in practice through:

• Definition and management of critical controls in Mining and Smelter operations: catastrophic loss scenarios were mapped, and the respective critical controls were established; these are periodically inspected and audited based on reference standards and action plans aimed at continuous improvement.
• Critical risk protocols: protocols with specific requirements to prevent fatalities associated with the main risks present in metallurgical and mining operations are defined, communicated, and reviewed regularly.
• Dynamic risk assessment: Changes in processes, technologies, personnel, or operational conditions undergo a structured change management process, including hazard identification, risk assessment, and definition of necessary controls prior to implementation.
• Task risk assessment: activities are analyzed using management system tools, such as Work Permits and Task Risk Analysis, conducted jointly by leadership and the operators directly involved.
• Creation of reference standards: technical and operational standards are developed and maintained for activities classified as high-risk, guiding procedures, qualification requirements, equipment, and minimum controls.
• Reporting of risk conditions: workers have access to the “Fale Fácil” communication tool to record, in a simple and accessible manner, hazardous situations, near-misses, and opportunities for improvement identified during routine operations.
• Systematic monitoring by leadership: there is a structured schedule for verifying and supporting risk management at all levels of the organization, ensuring the effective use of tools, the quality of analyses, and the implementation of continuous improvement actions.
