Materiality Matrix

Materiality Matrix

In our materiality analysis, we consider material topics those that significantly impact Enel Brasil's operations, reputation, and long-term sustainability. These topics reflect areas where the company is focused on ensuring continuous improvements by implementing policies, practices, and specific actions to meet the demands and expectations of stakeholders and society as a whole.

At Enel, we adopt the concept of dynamic materiality, which involves constantly monitoring stakeholder expectations by identifying and assessing priority issues for both external and internal audiences. We are dedicated to understanding the perceptions of our diverse audiences regarding our operations throughout 2023 and are committed to the continuous evaluation, reduction, and compensation of current and potential impacts we generate on society and the environment. Additionally, we evaluate the impacts that may result in risks or opportunities for the company.

To ensure alignment with our stakeholders' expectations, we annually review our materiality matrix. This process allows us to identify the most relevant topics that may influence our business or be affected by our actions. We use internationally recognized standards such as the GRI guidelines for disclosing the materiality matrix, the IIRC principles for integrated reporting, the AA1000 accountability standard, and the SASB indicators for the energy sector. These standards help us identify environmental, social, and governance issues that may impact our financial performance.

As signatories of the UN Global Compact, we also consider the 10 Principles of the Compact and the Sustainable Development Goals during this review. This type of materiality provides guidelines for our strategic planning, including the company's main impacts on the environmental, people, human rights, and economic pillars.

In 2023, we analyzed the results of 59 engagement initiatives with our main stakeholders conducted between June and July. Some of these specific initiatives included:

• Sending a virtual questionnaire to all employees and interns of all companies and business lines, public representatives at the municipal, state, and federal levels, service providers and material suppliers, a sample of customers, consumer councils of distributors, union representatives, disadvantaged groups and minorities (quilombolas and indigenous people), NGOs, community leaders, and local owners and citizens.
• Presentation of the results of the Global Climate Survey (internal).
• Documentary analysis including evaluation of documents from organic relationships with stakeholders such as media impact reports and results from the Perceived Quality Satisfaction Index (ISQP) among others.

These initiatives are fundamental to ensuring that our actions are in tune with stakeholder expectations and that we continue to progress towards a more sustainable and responsible operation.
