MATERIAL FACT

STRATEGIC PLAN 2024-2026:

GUIDANCE UPDATE

TIM S.A. ("Company" or "TIM) (B3: TIMS3; NYSE: TIMB), in compliance with Article 157 of Law No 6,404 and the provisions of CVM Resolution N. 44, and, in addition to the Relevant Fact disclosed on February 6, 2024, inform its shareholders, the market in general and other interested parties about the updated projections disclosed on that date, complementing the projections with estimates regarding Shareholder Remuneration.

Reiterating the material fact disclosed by the Company on February 6, 2024, for this new three-year period, TIM intends to continue developing and executing this strategy with adjustments to Brazil's macro-economic and business environment. For its main line of business, mobile, it projects a continuous and sustainable improvement in the market, driven by: (i) a new, more rational, market dynamic with customers focused on value and quality, (ii) essentiality of the service mobile, (iii) opportunity to increase usage with increased demand for data, and (iv) price accessibility.

This scenario projects sustainable growth in Service Revenue above inflation and an expansion of EBITDA with positive evolution in the margin. This dynamic combined with maintaining the level of investments that benefit from the efficiency of new technologies, should promote an improvement in the EBITDA-AL minus CAPEX indicator, which is a relevant driver for TIM's Operating Cash Flow. All of this will enable the Company to continue evolving its shareholder remuneration strategy and reinvesting in growth avenues such as B2B and Broadband.

Therefore, the Company projects around R$12 billion in shareholder remuneration for the 2024-26 period, following the continuous evolution proposal previously announced.

This completes the table with all the Company's projections for the next three years:
