Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	Policies and Procedure The purpose of information security and cybersecurity is to define the general guidelines regarding the Information Security Governance and Management System (SGGSI) and which must be known, adopted and complied with by all employees of the company, as well as third parties linked to it. SQM defines that the effective Governance and Management of Information and Operation Technology Security (IT/OT) is a business function and as such a critical element for the success and survival of SQM in a globalized and highly competitive world. An information security strategy is developed and implemented in alliance with business strategies, information technologies (IT) and operational technologies (OT). The scope and extent of the information security strategy depends on the size, complexity of the company, its business activities, risks, vulnerabilities and threats, providing a reasonable defense against any internal or external attack. This cybersecurity strategy addresses preventive, detective, corrective and reactive measures. Also, an important aspect is the information security incident management life cycle, which consists of being able to methodologically analyze Information Security & Cybersecurity (ISC) events/incidents from a point of view of the impact they could cause to the company. Incident response methodologies generally emphasize preparedness, not only establishing an incident response capability, but also preventing incidents by ensuring that systems, networks and applications are sufficiently secure. Preparation involves implementing the appropriate tools and configuring appropriate processes and procedures for treatment before an incident occurs. One of the most important tasks is to identify the assets that must be protected. We have incorporated cybersecurity related risks into our overall risk management system, which is built considering international standards, such as ISO 31000 and COSO ERM (Committee of Sponsoring Organizations Enterprise Risk Management), and includes the following stages: Risk Identification: To identify the risks, meetings will be held between the business risk management area and the different process owners of each business unit or business areas, who, due to their responsibilities, can be presumed to understand significant risk situations. Based on this input, the Business Risk Management Department will prepare a list of the risks identified for each unit. This list will be called a "risk inventory". Risk Analysis: Risk analysis includes the study of the causes and consequences in the event of a risk materialization. A risk can have multiple causes and consequences, which can affect more than one risk, so its correct identification will provide an in-depth analysis of the risk and its possible consequences. For any critical risk related to our strategic objectives, such as the risk of cybersecurity, a cause-consequence analysis must be performed, which is registered in a Bow-Tie sheet, which will help to better identify the controls that mitigate such risk. This analysis will be reviewed at least once every six months by the Business Risk Management Department and the responsible area. Risk Assessment: For any critical risk related to the Company's strategic objectives, such as the risk of cybersecurity, a cause-consequence analysis must be performed, which is registered in a Bow-Tie sheet, which will help to better identify the controls that mitigate such risk. The Bow-Tie analysis is a risk management technique that provides a visual representation of potential hazards, the threats that could cause those hazards, the consequences of those threats, and the controls in place to mitigate the risks. The name "bow-tie" comes from the shape of the diagram, which resembles a bow-tie with the hazard in the center and the threats and consequences branching out on either side. This analysis will be reviewed at least once every six months by the Business Risk Management Department and the responsible area. Risk Treatment: Once the residual risk has been defined, there are different ways of dealing with the risks based on the risk management methodology, which must be considered on a case-by-case basis. The way in which risk is dealt with will depend mainly on the risk appetite defined for each case. Risk Monitoring: The Business Risk Management Department continuously monitors the action plans committed by each responsible area. Risk Communication: At least twice a year, the Business Risk Management Department will present SQM's critical risks, such as cybersecurity, to the Board of Directors directly, or through the Directors' Committee, so it may then report to the Board of Directors. Upon receipt of information regarding critical risks, the Board of Directors may request further details during the Board meeting or engage in discussions about the risks and/or mitigation measures with the respective responsible party. SQM Business Risk Management Department is responsible for performing all the above described stages of the process. Every three years, SQM's Business Risk Management Department requests a evaluation of SQM's risk management function. This evaluation is conducted by an external audit firm and includes a review of governance, processes, culture, and supporting systems, comparison with an industry benchmark, and recommendations. The most recent evaluation was conducted in 2024.
