VINCI PARTNERS APPOINTS SONIA FAVARETTO AS NEW BOARD MEMBER TO BOOSTESG PRACTICE

Rio de Janeiro, August 13, 2021 -- Vinci Partners Investments Ltd. (NASDAQ: VINP) ("Vinci Partners,” "we," "us," or "our"), the controlling company of a leading alternative investment platform in Brazil, announced today that pursuant to written resolutions of its Board of Directors dated August 13, 2021, Ms. Sonia Consiglio Favaretto was appointed as director to the Board of Directors, effective immediately. Ms. Favaretto will assume the Chairperson position on Vinci Partners’ ESG Committee and will serve as a member of our Audit Committee.

Alessandro Horta, Chief Executive Officer, said, “We are very pleased to welcome Sonia Favaretto to Vinci Partners’ Board of Directors. Sonia is an experienced Director, with a demonstrated history of working in the financial services industry, highly skilled in corporate social responsibility, sustainable development, environmental awareness, and corporate communications. Ms. Favaretto’s appointment marks a new milestone in Vinci Partners’ path of differentiation as an environmental, social and governance (ESG) market leader, as we seek to upgrade our Impact monitoring KPIs and increase focus on ESG as an investment matter.”

Ms. Favaretto is a well acknowledged ESG and corporate communications expert in the financial services industry, having been recognized in 2016 by the United Nations Global Compact as a Sustainable Development Goals (SDG) pioneer, among only ten people in the world. She is the current president of the Brazilian Board for the Global Reporting Initiative, having served previously as a Director at the Brazilian stock exchange (B3), assuming the role of president of the Deliberative Council of the Corporate Sustainability Index (ISE), and president of Rede Brasil for UN Global Compact. She served as director of HR and internal communications and superintendent for BankBoston, superintendent of sustainability and institutional communications at Banco Itaú, and director of social responsibility at Febraban.

Ms. Favaretto’s appointment reinforces our commitment to diversity, as we now have two women as directors among four independent members on our Board, out of a total of eight seats, composed by Mr. Gilberto Sayao, Mr. Alessandro Horta, Mr. Paulo Fernando de Oliveira, Mr. Lywall Salles, Ms. Ana Marta Veloso, Mr. Rogério Werneck, Mr. Guilherme Stocco and Ms. Sonia Favaretto.
