NOTICE TO THE MARKET

TIM and FCA close unprecedented partnership for connected cars

TIM S.A. ("TIM" or “Company”) (B3: TIMS3; NYSE: TIMB), communicates to its shareholders, the market in general and other stakeholders the following:

TIM and Fiat Chrysler Automobiles (FCA) have established a partnership to offer connectivity solutions for vehicles of the Fiat, Jeep and RAM brands in Brazil from the first half of 2021. As part of the global strategy to develop ecosystems for connected services and enhance the digital experience of customers, future FCA’s launches in the country will feature eSIM, a virtual chip for onboard native Wi-Fi access, with the quality of TIM's 4G coverage and Internet of Things ("IoT") network.

The connectivity will allow the car to communicate actively and in real time with the customer, the FCA and the dealers network. FCA customers will benefit from a variety of services, from entertainment and security content to applications that interacts with the vehicle. It will also allow the remote identification of possible vehicle failures with the possibility of more agile and accurate diagnostics. All this thanks to the connected sensors, which continuously send data to the FCA.

The partnership strengthens TIM's presence in the segment of services provided to companies – B2B, inaugurating its operations in the vertical of connected cars that joins the solid portfolio of IoT solutions. At the same time, it enables the opening of new ways of reaching the customer in the segment of services provided to consumers – B2C, through the provision of "in-car" services.

The union of companies presents an opportunity to promote complete experiences to consumers, offering everything that is already possible in a smartphone through a connected vehicle. This agreement is a demonstration of the importance of strategic partnerships, stimulating and developing new business models, always offering the best experience for users.
