This commitment reinforces the creation of shared value with society, respect for the environment, and contributions to the country's economic and social development, while considering the needs of future generations.

Goals and Commitments
Double Materiality
In 2025, the Company advanced the update of its materiality assessment by adopting the double materiality approach, which considers both TAESA's impacts on the environment and society and the risks and opportunities capable of influencing its performance and value creation.
This evolution strengthens decision-making, enhances risk management, and guides initiatives aimed at advancing a more responsible and resilient operation committed to the future of Brazil's electric power industry.
10 material topics:
The Company's material topics and the UN Sustainable Development Goals (SDGs) they represent.
The updated materiality matrix enabled a complete reorganization of the material topics, reflecting a broader perspective more closely connected to the impacts, risks, and opportunities identified through the new double materiality process. Topics previously addressed separately were expanded, integrated, or renamed to properly represent TAESA's strategic priorities and the challenges of the electric power industry.
Beyond its commitment to being a company that values sustainability, the Company incorporates the UN SDGs into its corporate strategy. Since the 2024 Sustainability Report, the SDGs have been incorporated in a structured manner, creating a clear connection with the Company's Material Topics, and reinforcing the integration between the global sustainability agenda, business strategy, and value creation for society.

Economic
Green Bonds
TAESA has established its Green Finance Framework, a document that sets clear guidelines on how the Company issues, manages, and reports Green Bonds. The framework follows the Green Bond Principles ("GBP") of the International Capital Market Association ("ICMA"), which guide the selection of eligible projects, the proper use of proceeds, and transparency regarding environmental outcomes. Among the categories recognized by the GBP is electric power transmission, considered eligible because it directly supports the integration and delivery of renewable energy sources into the National Interconnected System ("SIN").
The funds raised by TAESA through Green Bonds finance and refinance transmission projects that expand the capacity of the SIN to integrate renewable energy, supporting the decarbonization of Brazil's electric power industry. The environmental performance of these projects is shown through specific indicators, such as the "Transmission Service Indicator for Green Users," which measures the increase in transport capacity for non-conventional renewable energy sources (solar, wind, biomass, and small hydro plants).
In 2025, TAESA carried out three Green Bond issuances, continuing the initiative launched in 2019 and reinforcing its strategy to finance projects aligned with the energy transition and the sustainable development of the electric power industry.
