What are the most significant cases or transactions that your legal team has recently been involved in?

Recently, our legal team has been involved in a number of highly relevant strategic and institutional matters, several of which are confidential in nature. Among the most significant matters which I can disclosure, I would highlight the following:

First, we worked on the structuring of the Company’s sanctions policy, including the design and implementation of the background check procedures necessary to support it. This initiative was particularly important to strengthen the Company’s compliance framework, mitigate legal and reputational risks, and ensure greater security in relationships with counterparties, suppliers, business partners, and other relevant stakeholders in cross-border transactions and regulated markets.

Second, we were involved in the structuring of the Company’s corporate governance committees, a project aimed at enhancing decision-making processes, increasing management transparency, improving internal controls, and reinforcing accountability across key business areas. This governance enhancement is expected to generate long-term institutional benefits, including greater organizational maturity, better risk oversight, and improved alignment between management and strategic objectives.

Third, we supported the improvement of the Company’s operations with a view to achieving greater tax efficiency, generating gains of approximately US$ 100 million (yellow marked – confidential). This work required a highly coordinated legal and operational approach, involving the review of structures, flows, and business arrangements in order to optimize the tax burden while preserving legal certainty and regulatory compliance.

Finally, we also worked on the structuring of our European subsidiary, which represented a relevant strategic step for the Company’s international expansion. This matter involved legal analysis and implementation efforts related to corporate, contractual, regulatory, and governance aspects, and was instrumental in supporting the Company’s broader global business strategy.

What new pressures are you facing from the business as expectations for legal to act as a strategic partner continue to grow?

The company is currently undergoing a period of strong growth in Brazil, including the construction of new ethanol plants, which has significantly increased the complexity and volume of its operations. At the same time, the diversification of its activities and products, combined with a broader international presence, has created new pressures for the legal department to operate as a truly strategic business partner. This requires the legal team to adapt quickly to the Company’s new scale and profile, not only by ensuring continued compliance with applicable laws and regulations, but also by providing a more critical and forward-looking assessment of legal, regulatory and commercial risks in support of the Company’s expansion strategy.

How have economic fluctuations, exchange‑rate volatility or supply‑chain pressures in 2026 influenced your legal priorities?

As Brazil’s largest ethanol producer, the Company played an important role in helping the country better absorb the reduction in international gasoline supply, as well as the significant price volatility observed in 2026. This scenario created relevant opportunities for the business, but it also brought substantial legal challenges. Government interventions in the fuel and energy markets generated considerable legal instability, requiring our legal team to remain highly adaptable and responsive. As a result, our legal priorities were strongly focused on monitoring and interpreting new tax and regulatory rules, assessing their impact on the Company’s operations and commercial strategy, and ensuring that the business could respond quickly and safely to a rapidly changing legal and economic environment.
