Suzano's supply chain comprises a variety of suppliers divided into main categories: operations, services, logistics, marketing, and sales, along with support functions like infrastructure and technological development. In 2025, we engaged with around 14,346 suppliers, creating a database of 24,165 entries. Our total supplier expenditure was about 43.3 billion reais.

Suppliers monitored by Procurement

Below, we detail the processes and policies implemented by the Responsible Supplier Management Program.

Governance

In 2021, we established the Responsible Supplier Management Program with the objective of maintaining rigorous oversight of our extensive supply chain and systematically incorporating optimal sustainability practices into procurement processes. This initiative is supported by a dedicated team responsible for monitoring and developing partners, reinforced by policies, procedures, and controls that enable continuous identification, assessment, and mitigation of ESG risks.

The Responsible Supplier Management Program is supervised by executive leaders from the Sustainability and Procurement areas, who conduct quarterly reviews of the implementation of initiatives aimed at mitigating ESG risks. Furthermore, as this constitutes a strategic matter for the company, the program''s initiatives are reported to the Vice-Presidency and deliberated in COMEX meetings. It is noteworthy that certain buyers have their variable remuneration linked to strategic Procurement metrics.

Suzano's purchasing guidelines, such as the Sustainable Procurement Policy, are reviewed every 24 months to prevent possible violations of ESG requirements and ensure compliance with the Supplier Code of Conduct.

Contracting and Endorsement

The approval and registration process encompasses all suppliers, including the submission of mandatory documentation in accordance with the contracting segment. Sustainability requirements are integrated into this process, with an evaluation of mechanisms and strategies pertaining to social management and performance, corporate governance, quality management systems, integrity, due diligence, and environmental considerations.

To be contracted, suppliers must undergo a certification process to confirm they meet legal, technical, and compliance standards. They also engage in Procurement's supplier management activities, which verify their compliance with state regulations, ensure necessary licenses and documents are valid, conduct initial checks of quality and ESG standards, gather market data, and verify their adherence to the Supplier Code of Conduct.

To ensure adherence to minimum ESG requirements, all critical suppliers are required to complete a self-assessment including the following aspects:

• Social: respect for human rights and diversity, adherence to regular labor practices, and a commitment to eradicating child, forced, and compulsory labor;
• Governance: anti-corruption practices, Complaints Channel, and Code of Conduct;
• Environment: conscious water consumption, regular waste management, monitoring, and reporting of greenhouse gas emissions;
• Quality: proper mandatory documentation, ISO and FSC® certifications, quality management procedures and policies, and suitable infrastructure.

The certification process further encompasses a comprehensive background check (BKG) of eligible suppliers. This process involves verifying a variety of information (including reputational, administrative, judicial, criminal, and other records) concerning individuals and corporations registered within Suzano's supplier database.

Background check reports compile data from various sources, including media and legal analyses on ESG topics like environmental compliance, labor laws, anti-corruption, and criminal statutes. They also cover ethics and integrity, financial and fiscal health, reputation, and judicial or administrative proceedings. The validity of these analyses ranges from 6 to 18 months, depending on the supplier's score.

Suppliers are disqualified from entering into contracts when there is an irregularity and/or failure at any stage of the certification processes, including failure to achieve the minimum score required (over 30%) on any of the self-assessment questionnaires (covering quality, social, governance, or environmental aspects). The comprehensive procedure is detailed within the Sustainable Procurement Policy.

In 2025, 89.26% of suppliers were approved against environmental criteria, and 100% against social criteria. For further details, refer to the indicator “Total number and percentage of suppliers that have undergone environmental and social assessment.”

To evaluate the effectiveness of the approval process, critical suppliers are requested to complete the self-assessment questionnaire annually, and ESG compliance audits are conducted, as outlined in the risk management procedures section.

Selection of essential suppliers     

Below, we outline the methodology for selecting critical and priority suppliers for risk management and performance evaluations. Critical suppliers are defined as those that are commercially important and:

• They supply items with the potential to significantly influence product capacity or quality, process performance, safety of equipment, employees, and collaborators, as well as the health of staff and the integrity of equipment.
• Pose a high sustainability risk.      

To classify suppliers by sustainability risk, Suzano employs the Supply Chain Social and Environmental Risk Matrix, which establishes consistent ESG monitoring criteria aligned with our Commitments to Renew Life (CPRVs) and the United Nations (UN) Sustainable Development Goals (SDGs). By 2025, criteria from the Taskforce on Nature-related Financial Disclosures (TNFD) framework will also be incorporated for the evaluation of supplier risks, including Water and Effluent hotspots, Biodiversity, Raw Material Origin, among others.

The Social and Environmental Risk Matrix is created by segmenting the company's entire supplier base according to their sector, taking into account social, environmental, and governance factors. Suppliers in sectors with a high likelihood and severity of socio-environmental impacts, as well as a high degree of Suzano's co-responsibility, are categorized as having a high sustainability risk.

The company considers ESG aspects to be decisive factors in the supplier evaluation and selection matrix. This means that when suppliers are on equal footing, the company will prefer the one best positioned in terms of sustainability.

Risk management

Supplier management occupies a pivotal position in mitigating economic, environmental, and social risks within Suzano's value chain. Economically, we conduct financial qualification processes and continuously monitor indicators such as the Serasa score and levels of financial dependence, thereby reducing the risk of operational disruptions and fostering more stable and sustainable commercial relationships. From an environmental perspective, we promote responsible practices among our partners, including emissions control, proper waste management, and water security—elements vital to the resilience of territories and the production chain. Regarding the social dimension, our efforts focus on promoting respect for human rights, preventing instances of child, forced, or bonded labor, and ensuring decent and safe working conditions.

All these impacts are monitored through audits, periodic performance assessments, and compliance checks with relevant ESG standards, certifications, and criteria, thereby reinforcing our commitment to an increasingly ethical, transparent, and sustainable value chain.

We continued conducting a second-party external audit process for high-risk suppliers from a socio-environmental perspective, which we initiated in 2022. This process focused on the suppliers identified as priorities during the initiative's initial phase. Among the suppliers audited, 88% remain under surveillance via the Reprisk platform. Additionally, RepRisk provides supplier ratings [RepRisk Rating (RRR)] that assess company- and industry-specific ESG risks at the national level.

All audited suppliers are required to submit corrective action plans within 15 days of the publication of the results, addressing the issues identified. Corrective measures must be implemented within 90 days by suppliers who have failed our assessment, within one year by suppliers who have passed with restrictions, and within one year and a half by approved suppliers. Both the auditing firm and Suzano will continue to monitor and support the supplier throughout the implementation process.

Another significant initiative undertaken by Suzano with its key suppliers is the SSOMAR (Occupational Health, Safety, and Environment) assessment. This process evaluates the risks related to child labor, as well as forced and/slavery-like labor within the company's operations. It is conducted in accordance with established procedures, criteria, and verification tools aligned with the requirements of Regulatory Norms (NRs), FSC, PEFC, and pertinent national and international legislation, including Human Rights guidelines. The scope of this procedure extends to Company employees and service providers, ensuring a comprehensive and integrated approach.

Quarterly accommodation inspections are also conducted by the Health, Safety and Quality of Life (SSQV) team for all suppliers providing accommodation to support Suzano's operations.

We have made significant progress in our risk management processes through the establishment of the Proactive Supplier Risk Committee, tasked with discussing and determining Suzano's actions in the event of critical cases involving human rights violations by suppliers, thereby aiming to mitigate identified risks. The Committee comprises members from Procurement, Legal, Institutional Sustainability, Corporate Risks, and other relevant departments as appropriate.

We utilize the ESG Consequence Matrix, structured in 2024 by external experts, which is employed in cases of deviations, irregularities, and/or illegalities committed within or outside the scope of the contract. The Matrix comprises a decision tree integrated with other supplier risk management procedures and delineates the situations deemed as deviations, their severity and pertinence, as well as the potential consequences for suppliers, such as notifications, penalties, action plans, etc., depending on the seriousness and significance of the violation.

Supplier performance assessment

The Supplier Performance Index (SPI) program assesses critical suppliers based on quality, environmental standards, social responsibility, and safety requirements. In 2025, the average approval rate was 99.7%. For suppliers falling below the specified index, Suzano's contract managers formulate corrective and improvement strategies and monitor the implementation of such corrective actions. Non-compliance with the prescribed actions may lead to the suspension, blocking, or disqualification of the supplier from our database.

Supplier engagement and development programs in ESG aspects

In pursuit of our dedication to supporting and empowering our suppliers, we have initiated multiple projects aimed at enhancing the involvement of our supply chain in ESG matters.

The Semear project, in partnership with Sebrae, an organization that promotes entrepreneurship in Brazil, is a 6- to 12-month support program. It aims to train and enhance the ESG performance of Suzano's micro and small suppliers. Participants learn best practices in management and innovation, as well as principles of legal, social, and environmental responsibility. Additionally, we developed a specialized version of the program focused on female entrepreneurship, targeting socially vulnerable women living in communities near Suzano's sites in Brazil.

The Climate Change in the Value Chain and Caring for Water in the Value Chain programs encourage suppliers to reduce greenhouse gas emissions and enhance water management. To support this, we have teamed up with the Carbon Disclosure Project (CDP) to help our suppliers measure, disclose data, set goals, and evaluate risks and opportunities related to climate change and water use.

We also help expand knowledge on the subject throughout the value chain through training programs, workshops, and webinars held by CDP and Suzano. Through CDP, cyclical meetings are held to share best practices, allowing our suppliers to access ESG benchmarks. The suppliers selected to take part in these programs are those with the greatest commercial relevance for the company among those identified as high risk in the “Greenhouse Gas Emissions” and “Water and Effluents” hotspots by the Social and Environmental Risk Matrix.

In 2025, we asked 200 suppliers to share their climate data, and 75% participated, exceeding the global average for the CDP Supply Chain program. Regarding water security, we invited 100 suppliers, and 86% joined the program.

Suzano offers the Inclusive Procurement program to suppliers, aimed at engaging and motivating our supply chain to enhance diversity, equity, and inclusion. This involves identifying and supporting diversity initiatives across our Procurement network, such as conducting a Diversity and Inclusion Census among our suppliers.

A key aspect of this project is our collaboration with JSL, a Brazilian logistics company, through the Women in Management initiative that trains women to operate forklifts at Suzano locations in Brazil.

 Our partnership with WEConnect International, established in 2024, persists as a strategic alliance connecting women-owned enterprises to prominent organizations globally, with the objective of enhancing diversity within Suzano's supply chain. We monitor the indicator of diverse procurement, enabling us to better identify our expenditures with women-owned businesses. Furthermore, the initiatives of the Inclusive Purchasing program received recognition at the 2025 Procurement Leaders international awards in the Supplier Inclusion category.

We also conduct supplier engagement events via the Share Program, focusing on two main areas: climate and positive social impact. For the climate initiative, we invited 100 strategic suppliers, representing 80% of our total spend on goods, services, and upstream transportation and distribution, aligning with the SBTi target. The program involves activities like signing a letter of commitment to formalize supplier adherence (70% participation), completing a maturity questionnaire and collecting primary data on emissions (78% participation), following up on action plans developed by Suzano and monitored with suppliers, and participating in workshops and training sessions to enhance technical skills and share best practices (77% participation from new and developing suppliers). On the social impact front, the aim is to engage the supply chain to support poverty alleviation through co-funded projects and workforce training aligned with business needs. We engaged 25% of the suppliers identified for potential partnerships.

We also organized the third Suzano Valoriza edition, a program designed to acknowledge our suppliers' performance and ESG scores. Furthermore, we hosted the Best Practices event, inviting suppliers recognized in Suzano Valoriza to share their sustainability and innovation initiatives, promoting knowledge exchange and successful case sharing.

In 2025, we held the Socio-Environmental Awareness Tour to introduce concepts and best practices in human rights and environmental governance, reaffirming Suzano's strategic goal of reducing risks and ensuring due diligence in human rights and fair labor practices. The initiative also aimed to strengthen our relationships with suppliers. To support this, we updated the Supplier Code of Conduct to align with new international regulations, particularly regarding human rights due diligence, ensuring suppliers uphold fundamental rights throughout the entire value chain. We also introduced new resources like the Human Rights Manual and the Golden Rules, which will guide the entire value chain. The tour traveled through ES, BA, MA, MS, and SP, engaging about 140 suppliers and reaching 25% participation. Additionally, in partnership with the UN Global Compact, ILO, and IBÁ on human rights, we trained 30 sector suppliers on decent work issues, broadening our efforts to protect human rights.

Nossa Voz Florestal

Suzano is launching the Nossa Voz Florestal project (Our Forest Voice) as a pilot in Bahia and Espírito Santo. The goal is to improve social listening and dialogue, as well as reduce labor and human rights risks in the forestry supply chain. Using a participatory approach, the initiative involved consultations with 61 workers to adapt the tool to their needs and provided training for 110 municipal civil servants. This strengthens the capacity of local governments and promotes a more resilient, responsible production chain. In this first cycle, over 500 workers across Suzano's value chain received training in Nossa Voz.

Nossa Voz Florestal is a free, accessible, and independent platform for reporting concerns, primarily through WhatsApp. Operated by the International Labor Organization (ILO), it serves as an early warning system to detect and address risks such as child labor, forced labor, and violations of freedom of association. The initiative highlights Suzano's dedication to collaborative efforts, cross-sector initiatives, and the enhancement of social dialogue, particularly with rural workers in isolated areas, landless farmers, and forest suppliers.

Internal engagement

In addition to initiatives focused on supplier development, the Responsible Supplier Management Program offers training on Environmental, Social, and Governance (ESG) topics for the company's purchasing personnel. For instance, in 2025, training sessions encompassed Life Cycle Assessment and Circular Economy, with the participation of 91 buyers, accounting for 53% of the total workforce. Furthermore, the Responsible Purchasing Track is available on the UniverSuzano internal training platform, covering subjects such as climate change, water management, and ESG initiatives within the supply chain.

We also conduct an annual training program for the teams responsible for wood procurement, ensuring education in land, social, labor, health, safety, and environmental regulations. In 2025, thirty-five internal employees participated in the training.

Implementing technologies

We have advanced automating and analyzing data to enhance risk prediction, streamline supply chain audits, and support better decision-making for responsible purchasing. To help achieve this, we have signed and upheld key partnerships, including those with Linkana and RepRisk.              

Wood suppliers

The supply of wood, evaluated from environmental, social, economic, and legal perspectives, is classified in the Socio-Environmental Risk Matrix as critical and high risk for sustainability (Sustainable Procurement Policy). 

As an additional risk assessment method, internationally recognized certification standards and regulations, such as FSC®, PEFC, and SFI® standards, the National Risk Analysis for Brazil and the United States, the European Timber Regulation (EUTR), and the United Kingdom Timber Regulation (UKTR) are utilized, as outlined in the Timber Procurement Policy. 

The processes for monitoring and risk mitigation are elaborated in the indicator “Total number and percentage of suppliers that have undergone environmental and social assessments.' 

Committed to promoting sustainable practices within the supply chain, Suzano encourages its wood suppliers to obtain Responsible Forest Stewardship certifications. To verify the responsible origin of wood from partners not participating in the Forest Stewardship certification program, a Due Diligence System/Monitoring Program is implemented, based on the company's Wood Procurement Policy, international regulations, and FSC® Controlled Wood/PEFC and SFI® standards applicable to wood suppliers in the United States. 

Due diligence encompasses the assessment and mitigation of risks across the supply chain, commencing at the pre-contract stage for wood purchases and continuing through to delivery at mills, with verification of compliance with environmental, social, legal, and labor standards through first-party, second-party, and third-party audits conducted by independent organizations. This practice covers both direct wood suppliers and indirect suppliers involved in harvesting and transportation.
