**Ref.: Official Letter 27/2026-SLE**

**Subject:** Request for clarification on news published in the press

Dear Madam,

**1.** In compliance with Official Letter No. 27/2026-SLE, of 02/02/2026, through which this Superintendence requests clarification on information published in the article "TIM Brasil negotiates to buy back majority stake in fiber optic unit, sources say", published by the newspaper Valor Econômico on 02/02/2026, we transcribe below the highlighted excerpts, followed by the statements of TIM S.A. ("TIM" or "Company"):

· "*Telecoms operator TIM Brasil is in talks to buy back a 51% stake in the I-Systems fiber optic network it previously controlled, in a deal that could be worth about $170 million, two people with knowledge of the matter said* "; and

· "*The stake in the unit, which would give TIM Brasil full operational control of the business, could be valued at around 900 million reais, said the two sources, who declined to be identified because the negotiations are not public*."

**Company Clarifications**

**2.** As disclosed by the Company in its Strategic Plan, as well as in previous communications to the market, the Company continuously evaluates strategic alternatives and opportunities that can contribute to the strengthening of its broadband services and the improvement of its telecommunications infrastructure, always with a selective approach focused on efficiency and quality.

**3.** In this scenario, the Company confirms that it has non-binding negotiations with IHS Fiber Brasil – Cesssão de Infraestruturas Ltda. ("IHS Brasil") related to the potential acquisition of an interest in the company I-Systems Soluções de Infraestrutura S.A. ("I-Systems"). Such negotiations are still in progress, with no conclusive definition of their terms and conditions, and are part of the ordinary course of evaluation of strategic alternatives regularly conducted by the Company.

**4.** The article mentions estimates and information attributed to unidentified sources of aspects of the transaction for which there is still no definition within the negotiations that have been carried out.

**Disclosure to the market**

**5.** Considering the publication of the journalistic article, the Company, spontaneously and in line with the best practices of transparency, published a Material Fact yesterday, clarifying that the aforementioned negotiations are not binding and are still in progress.

**6.** The purpose of the disclosure was to ensure the adequate, isonomic and transparent dissemination of information to the market, mitigating the risk of informational asymmetry resulting from the potential reported leak.

**Absence of atypical oscillation**

**7.** In addition, the Company informs that, in line with the usual checks carried out within the scope of its continuous monitoring obligations, no atypical fluctuations were identified in the trading of shares issued by TIM or in their respective derivatives that could indicate improper use of privileged information or direct correlation with the content of the aforementioned journalistic article. The evolution of quotations and traded volumes remained within standards compatible with recent historical volatility and with the usual behavior of the Company's securities, and there was no indication of distortion or abnormal movement in the period analyzed.

**Conclusion**

**8.** In view of the foregoing, the Company: (i) confirms the existence and continuity of non-binding negotiations regarding negotiations involving the potential acquisition of a stake in I-Systems; (ii) does not confirm the amounts mentioned or any other details disclosed in the news; (iii) reinforces that any transaction will depend on internal analyses, usual conditions precedent, applicable corporate and regulatory approvals; and (iv) reiterates that it will keep the market informed of any relevant developments, under the terms of the regulations in force.
