Notice to the Market
Partnership between TIM and IHS Brasil for Tower Infrastructure Expansion
TIM S.A. (“TIM” or “Company”) (B3: TIMS3; NYSE: TIMB), in accordance with Article 157 of Law No. 6,404 and the provisions of CVM Resolution No. 44/21, hereby informs its shareholders, the market in general, and other interested parties that it has entered into a partnership with IHS Brasil – Cessão de Infraestruturas Ltda. (“IHS Brasil”) for the construction and operation of telecommunications towers (“sites”).
The partnership aims to build up to 3,000 units under the MAKE1 model, with an initial minimum deployment of 500 sites. The sites will be distributed across various regions of the country and may be used for both B2C and B2B operations, especially in IoT (Internet of Things) projects in verticals such as agribusiness and highways.
TIM and IHS Brasil already collaborate in other business areas. However, this partnership establishes innovative methods for tower construction and is one of the initiatives under TIM’s Lease Efficiency Plan (“Efficiency Plan”), which has been previously disclosed to the market.
IHS Brasil’s know-how will support TIM by accelerating the restructuring of its mobile coverage evolution strategy, strengthening the development of the B2B segment, and improving the quality of mobile service. Financial gains are expected in lease expenses, with no material impact on TIM’s investment plan (capex).
The Company will keep its shareholders and the market in general informed, pursuant to CVM Resolution No. 44 and applicable legislation, regarding relevant updates related to the Efficiency Plan, which still includes (i) other MAKE model initiatives, (ii) the evolution of the infrastructure sharing project, and (iii) the renegotiation of contracts for towers already deployed.
Rio de Janeiro, October 7, 2025.

1 The MAKE model refers to the construction of one's own sites with or without the help of third parties/partners in the process.
