In Brazil, some of the areas where we operate face heightened water stress, characterized by scarce water resources and rising competition. Since our operations rely heavily on water-related ecosystem services, alterations in natural conditions can impact both the availability and quality of these services, potentially creating physical and transition risks for the business.

We acknowledge our responsibility for water management within the river basins we operate in, considering not only our own use but also our shared duty to other users relying on the same resources. To prevent issues and support ongoing improvements in environmental quality, Suzano designs and implements both direct and indirect actions to ensure water resource availability.

Based on the watershed mapping in our operational areas in Brazil, we identified 44 critical watersheds¹. For each, we conducted a detailed environmental diagnosis and provided technical recommendations for forest management actions² that can positively affect the water balance. These actions, which involve increased planting spacing and the creation of an age mosaic, are central to our corporate target, measured by the hectares implemented in the critical basins.

The company has committed to taking local mitigation actions to boost water availability in critical basins and enhance the resilience of these areas against water restrictions by 2030.

Implement forest management recommendations across Suzano's plantation areas to boost water availability in 44 critical watersheds. This covers a total of 88,400 hectares in Brazil, where our operations are based.

Implement forest management to increase water availability in critical watersheds¹ within Suzano's operational areas by 2030.

In 2025, we surpassed our annual target by 16% by implementing management actions across 5,806 hectares in critical basins. These measures included using age mosaics and increasing planting spacing, aiming to lower water demand pressure.

A key challenge of this commitment is monitoring water availability in critical basins. To address this, in 2025, we launched an innovative satellite-based platform to measure water in forests. Developed through a partnership between Suzano and the startup Marvin Blue, this tool will enhance hydrological monitoring and water management in basins with management actions in place, thereby supporting the achievement of this goal.

Additionally, we maintained our monitoring efforts in key basins by installing new checkpoints in rural areas (in situ monitoring). This enhances local data collection and improves our capacity to track and assess the impact of our actions on water resources.

Acknowledging the vital role of springs and rivers as primary water sources, we advanced a project to protect and revitalize these natural sources, particularly in critical basins. In 2025, we developed an innovative machine-learning model that maps springs in sensitive basins using remote sensing. This technology enables more accurate identification of springs requiring environmental quality assessments, improving the targeting of conservation efforts. Using this prioritized approach, we selected a pilot spring for forest restoration activities. This innovation has streamlined the process of identifying and choosing springs, resulting in quicker, more effective interventions where they are most needed.

In 2026, the main actions planned include:

1. Implementation of age mosaic management and increased planting spacing in the planned areas, following the premises defined for each type of management
2. Continue research and development projects, focusing on improving the accuracy of tools for monitoring management actions' evolution (procedural and satellite modeling).
3. Finalizing the installation of checkpoints in rural areas (in situ monitoring) for water monitoring in the critical watersheds.

These integrated initiatives consolidate Suzano's focus on applying and expanding forest management actions that positively influence the water balance, moving towards our goal of increasing water availability in the critical watersheds where we operate.
