Overview, Indicators and Indexes

TIM believes that its business activities must be carried out taking into consideration the expectations of all those we interact with, the so-called stakeholders (that is, all people or things affected by our activities). We group our stakeholders in eight categories: customers, suppliers, competitors, institutions, the environment, community, shareholders (external stakeholders) and Human Resources (internal stakeholders).

We listen to all our stakeholders’ feedbacks not only because we believe that it is right from the ethical standpoint, but also because we are convinced this is the only way to sustain our business in the long term.

TIM’s goal is to achieve balance in the dimensions of economic, environmental, social and governance sustainability. From this perspective, “ESG” comes from the term “Environmental, Social and Governance” and it is directly linked to TIM’s position. We have showed over the years our engagement with the highest level of corporate governance, economic responsibility and strong commitment to social and environmental aspects.

This commitment allowed us to be the only company in the sector to be listed in the B3’s Novo Mercado, to maintain a Statutory Audit Committee, to be part of the ISE portfolio for 17 consecutive years and to be a member of the S&P/B3 Brasil ESG index.

Aligned to our Values and to the sustainability principles described, we also operate in accordance with a set of Policies that rule different aspects related to ESG. In addition, in December 2020, TIM created the ESG Committee to advise the Company’s Board of Directors on issues related to environmental, social and governance. The committee is composed of members of the BOD.

In addition, TIM considers the following topic as materials in its sustainable evolution, defined from qualitative and quantitative analyses to identify the importance of each topic, in line with Global Reporting Initiative (GRI) guidelines and recommendations:

Themes identified as priorities in the materiality process

Energy management
Responsible supplier management
Artificial intelligence

Climate change
Cybersecurity, privacy and data protection
Non-compliance with regulatory obligations

Diversity, inclusion and nondiscrimination
Digital inclusion and connectivity
Service quality and customer experience

The periodic process of preparing the materiality matrix includes consulting the company’s external and internal stakeholders. It is one of the mechanisms that enables frequent review of TIM’s ESG strategies, aiming at continuous improvement of its practices and commitments.

In 2024, TIM focused on developing its dual materiality, the main trend for defining material topics for organizations today, which has become mandatory for various reports, ratings, and initiatives.

This model is composed of two types of materiality: Financial and Impact (socio-environmental). Impact materiality involves issues that have a significant effect on the economy, the environment and/or people and society, caused by our activities and operations. Financial materiality brings together environmental, social, and/or governance issues that have a significant effect on our financial performance and our ability to generate value.

The new materiality matrix guides the reporting of information in the ESG Report, as well as being the basis for the development of TIM’s ESG strategy.

TIM’s activities towards sustainability and aiming the best ESG practices are recognized in assessments of the main ESG
indexes of stock exchanges and specialized agencies.
