Subject: Request for clarification on atypical oscillation

Dear Sir/Madam,

TIM S.A. (“TIM” or “Company”) clarifies the following, in compliance with Official Letter B3 nº 1479/2021 ("Official Letter"), of November 3^rd, 2021, issued by the Superintendence of Listing and Supervision of Issuers ("SLS") of B3 - Brasil, Bolsa, Balcão (“B3”), transcribed below:

“In view of the latest fluctuations recorded with the securities issued by this company, the number of trades and the amount traded, as shown below, we have requested that you inform by 11/4/2021, if there is any fact that you are aware of that can justify them.

* Updated until 01:55 pm.”

In this regard, the Investor Relations Officer clarifies that, at the moment, she is unaware of the existence of a pending material fact that could cause an atypical fluctuation in the price and volume of the company’s shares.

Nevertheless, it was published in the Cade Electronic System (SEI) [[1]], on November 2^nd, 2021 at 11:23pm, the Opinion No. 11/2021/CGAA04/SGA1/SG/CADE, its respective Annexes, and Order SG No. 1612/2021, under the Merger Act No. 08700.000726/2021-08, through which the General Superintendence (SG) of the Administrative Council of Economic Defense - CADE refers the Merger Act in question to the Administrative Court of CADE.

The Opinion points out that the General Superintendence recommended that Oi S.A.'s mobile asset acquisition operation, as communicated to the market through the Material Facts disclosed on March 10^th, 2020, July 18^th, 2020, July 27^th, 2020, August 7^th, 2020, September 7^th, 2020, December 14^th, 2020 and January 29^th, 2021, be approved by signing an Agreement on Concentration Control (ACC), in order to avoid potential competition concerns.

On November 3^rd, at 8:25am CADE also published on its website [[2]] a press release regarding this subject, as transcribed in the text below:

"Thereby, SG/Cade concluded that the ACC negotiated with companies is appropriate to preserve competitiveness in the market. The case will now be evaluated by the Court of CADE, responsible for the final decision. The conclusions of SG/Cade are not binding."

The Company understands that the recommendation of the General Superintendence of CADE is another stage of analysis of the Merger Act and that it has no binding nature. Thus, the Company continues to await the definitive approval by the Administrative Court of CADE. Additionally, the two publications, both of the Opinion and of the press release, occurred broadly and with the markets closed, being, therefore, the moment in which the Company and the market in general became aware of the fact, simultaneously.

Without any further clarifications, we remain at your disposal to provide any additional information that may be required.

TIM S.A.

Investor Relations Officer
