**HELD ON MARCH 18<sup>TH</sup>, 2026**

**<u>DATE, TIME AND PLACE:</u>** March 18<sup>th</sup>, 2026, at 4.00 p.m. Due to the importance and urgency of the matter on the Agenda, the meeting was held in the form of a virtual deliberative circuit, as provided in the 2<sup>nd</sup> paragraph of Section 40 of TIM S.A.'s By-laws ("Company").

**<u>PRESENCE</u>:** The Fiscal Council's Meeting of the Company was held with the presence of Messrs. Walmir Urbano Kesseli, Elias de Matos Brito and Heloisa Belotti Bedicks, regular members of the Company's Fiscal Council ("CF"), with Mrs. Fabiane Reschke, Secretary, also attended the meeting.

**Evaluation on the payment proposal of the Company's interest on shareholders' equity ("IE").**

Initially, a brief introduction was presented on the calculation methodology used for the payment of Interest on Equity ("IE") by the Company, as well as the management proposal for the distribution as IE, as follows: **(i)** the distribution of profits in the amount of **R$390,000,000.00 (three hundred and ninety million reais)** at **R$0.1632708888 (zero point one, six, three, two, seven, zero, eight, eight, eight, eight cents)** of gross value per share; **(ii)** payment will be made until **April 30<sup>th</sup>, 2026**, without the application of any monetary restatement index; **(iii)** shall be considered the date **March 23<sup>rd</sup>, 2026**, to identify the shareholders entitled to receive such amounts.

The gross amount per share may be modified due to the variation in the number of treasury shares.
