🧾 What This Document Is

This is a Form 6-K, a standard report that foreign companies listed on U.S. exchanges (like TIM on the NYSE) use to share important news with the SEC and investors. Think of it as a mandatory "heads-up" about a significant company event.

This specific report is a Notice to the Market announcing a key executive departure.

🏢 What The Company Does

👉 In simple terms, TIM is one of Brazil's largest mobile telecommunications companies. They provide wireless voice, data, and internet services to millions of consumers and businesses across Brazil. It's a major player in a highly competitive and regulated industry.

• Listed On: B3 (Brazilian stock exchange) as TIMS3 and NYSE as TIMB.
• Headquarters: Rio de Janeiro, Brazil.

💼 Executive Changes

The core news here is a resignation from the company's leadership team.

• Who Left: Ms. Fabiane Reschke resigned from her position as Legal Officer (often called the Legal Director).
• When: The resignation was received by the company on March 31, 2026.
• Company Response: TIM thanked Ms. Reschke for her service and wished her well. This is standard and shows a respectful departure.

⚖️ What Happens Next & Why It Matters

The Board of Directors will now evaluate the company's executive structure.

👉 Why it matters: The Legal Officer is a critical role, especially in a regulated telecom company dealing with contracts, compliance, and government relations. This departure creates a vacancy in a key C-suite position that needs to be filled to ensure smooth governance and operations.

• Process: The Board will decide how to fill the role—whether by appointing someone new or restructuring responsibilities.
• Investor Relations: For now, Mr. Vicente de Moraes Ferreira is listed as the contact person for investor relations at the bottom of the notice.

🌍 Industry Context & Signal

In the fast-paced telecom industry, leadership stability is closely watched. While executive turnover happens, the departure of a top legal executive can signal internal changes or a new strategic direction. Investors will be looking to see if this is an isolated event or the start of broader leadership shifts.

⚖️ Big Picture

• 👍 Strength: The company followed proper protocol by promptly informing the market, demonstrating transparency. The transition is being handled by the Board in an orderly manner.
• ⚠️ Risk: Any vacancy in a key officer role, even temporarily, can create uncertainty. The company must ensure a smooth handover to maintain operational and legal continuity.

🧠 The Analogy

This is like the star defender of a soccer team announcing they're leaving mid-season. The team (TIM) publicly thanks them, and the coach (the Board of Directors) now must decide whether to promote a promising player from within or start scouting for a big-name replacement to strengthen that critical position on the field.

📇 Key Contacts & People

• Fabiane Reschke: Former Legal Officer (Resigned).
• Vicente de Moraes Ferreira: Investor Relations Officer (Contact for the notice).
• Alberto Mario Griselli: Chief Executive Officer, Chief Financial Officer and Investor Relations Officer (Signed the SEC filing).

🧩 Final Takeaway

TIM S.A. announced the resignation of its Legal Officer, a significant C-suite role. The company's Board will now determine the next steps for this key leadership position in its Brazilian telecom operations.
