NOTICE TO THE MARKET

CLARIFICATION ON NEWS PUBLISHED IN THE PRESS

TIM S.A. ("TSA" or “Company”) (B3: TIMS3; NYSE: TIMB), in response to CVM Inquiry No. 163/2021/CVM/SEP/GEA-2, which requested clarification on news article published on the Infomoney website page on the internet on 11/22/2021, hereby informs its shareholders and the market in general:

The news article seems to be based on the widely disseminated news in international and local press, referring to a press release^[1] released by TIM S.p.A. ("Telecom Italia") on November 21^st, which reports the receipt of an indication of a non-binding indication of interest ("NBO") from the asset management KKR&Co. ("KKR") for the acquisition of at least fifty-one percent (51%) of Telecom Italia shares for the value of €0.505 per share through a possible public offering ("Transaction").

According to the press release, the NBO is conditioned, among other things, to a due diligence that should last four (4) weeks, and the approval of the Italian Government (Golden Power). Additionally, the press release makes no reference to TSA, either about direct or indirect impacts of the NBO on the Company, or to KKR's strategic plans for TSA if the Transaction occurs.

TSA reinforces that it has not received any direct contact or proposal from KKR, or any information or communication on the subject from Telecom Italia or from KKR. Thus, the only information that TSA has about the corporate matters that are in progress at Telecom Italia are those contained in the press release.

In this context, the Company considered that it was not appropriate to disclose a material fact, since the information held by the Company was only the information already made public and widely disseminated by Telecom Italia, at that time without any indication of a direct or indirect relationship with TSA.

TSA reiterates its commitment to provide, in a timely manner, the appropriate information to shareholders and the market whenever there is any material act or fact.
