1st Quarter 2024 Report

Solid ESG path

Generating positive and lasting value for society and shareholders has always been part of our business strategy. If today, environmental, social, and governance aspects, so widely disseminated in the ESG acronym, are considered essential in conducting any activity, for TIM, the sustainable development agenda is part of an evolutionary and intentional journey.

Continuously, we challenge ourselves with goals and commitments that contribute to building a fairer, more inclusive, and diverse society, and reduce environmental impacts, in pursuit of a circular and low- carbon economy. At TIM, the ESG theme is at the core of the business, becoming an increasingly crosscutting principle in all planned and executed actions.

National and international recognition is the result of a trajectory that has been built up over more than two decades. We are the longest-serving telecommunications company - 16 years - in the B3 Corporate Sustainability Index Portfolio. Since 2011, the company has voluntarily been part of the Novo Mercado, the highest level of corporate governance on the Brazilian stock exchange, as well as being the first national operator to be classified as a Pro-Ethics company by the Comptroller General of the Union (CGU).

As signatories of the UN Global Compact since 2008 and UN Women since 2021, we develop projects connect to the Sustainable Development Goals ("SDG") and recognizes the rights to data privacy, safe internet, access to information and freedom of expression as essential and unnegotiable.

Commitment to diversity and inclusion

We have adopted goals, commitments and implemented various initiatives on the themes of gender, race, LGBTI+ people, generations and people with disabilities, among others. In 2021, TIM became the 1st Brazilian operator to be included in the Refinitiv Diversity & Inclusion Index, occupying the 1st position in Telecom at a global level, a highlight it maintained in 2022 and 2023, also appearing as one of the four best companies in the world.

We were the first Brazilian operator to win the GSMA's Diversity in Tech international award, which recognizes worldwide organizations with practices in favor of equality, diversity and human rights in the technology sector. In 2023, we were once again included in Bloomberg's Gender Equality Index, which brings together companies from 45 countries, only 16 of which are Brazilian. We won the position of best company in Latin America in gender equity and 7th place globally. TIM was also the only operator to be included in IDIVERSA B3, the first Brazilian stock exchange index to consider gender and race criteria when selecting the companies that will make up its portfolio.

In the constant quest to build healthier, more inclusive and collaborative work environments, where people can be proud of themselves and achieve even better results, in 2024 we won the Top Employers Brasil seal for the third year running. TIM was also ranked 12th among the Best Companies to Work for in the country by Great Place to Work (GPTW) and has been a member of B3's GPTW Index.
