🧾 What This Document Is

This is a Form 6-K, a report that a foreign company listed in the U.S. (like Telefonica Brasil) uses to inform the SEC and investors about important events. This specific filing is the official minutes from a Board of Directors meeting held on March 26, 2026. Think of it as the detailed, public record of a major decision made by the company's leaders.

👉 In simple terms: The company's board met to approve a key executive change, and this document is the formal announcement.

🏢 What The Company Does

Telefônica Brasil S.A. (ticker: VIV) is Brazil's largest telecommunications company, operating under the well-known Vivo brand. They provide a full suite of services: mobile and fixed-line phone, internet, and TV for millions of customers across Brazil.

👉 Why it matters: As the top player in a huge market, its leadership decisions can influence its strategy and competitive position.

🚀 Key Move: A New Financial Chief

The central event of this filing is a change in the C-suite. The Board appointed Mr. Rodrigo Rossi Monari as the new Chief Financial and Investor Relations Officer (CFO).

• He starts: April 2, 2026.
• He replaces: Mr. David Melcon Sanchez-Friera.
• Why the change? Mr. Sanchez-Friera is leaving to become the CFO of Virgin Media O2 UK, a joint venture between Telefónica (Spain) and Liberty Global in the UK. This is framed as an internal move within the broader Telefónica group.

👥 The New Leadership Lineup

Following this appointment, the company's executive team (its "Board of Officers") is now set until after the 2028 Annual Meeting. The key leaders are:

• Christian Mauad Gebara – Chief Executive Officer (CEO)
• Alex Martins Salgado – Chief Operating Officer (COO)
• Rodrigo Rossi Monari – New Chief Financial and Investor Relations Officer (CFO)
• Ricardo Guillermo Hobbs – Strategy and Regulatory Officer
• Breno Rodrigo Pacheco de Oliveira – General Secretary and Legal Officer

👉 Why it matters: This shows a stable, defined leadership team. The CFO is a critical role, responsible for the company's finances and its communication with Wall Street investors.

🔮 What This Signals & What's Next

This is primarily an internal succession move, not a strategic pivot. The new CFO, Mr. Monari, is stepping into the role on April 2, 2026. The board expressed high esteem for the outgoing CFO, thanking him for his service.

The key question for investors will be how the new CFO continues to manage the company's financial strategy, capital allocation, and investor messaging. No other operational or financial updates were provided in these minutes.

⚖️ Big Picture: Stability vs. Transition

👍 Strengths/Stability: The move appears to be a planned internal transition within the larger Telefónica group. The board was unanimous, and the new leadership team is fully constituted, suggesting operational continuity.

⚠️ Risks/Transition: Any CFO change brings a period of adjustment. Investors and analysts will watch to see if Mr. Monari maintains the same financial priorities and transparency as his predecessor. The loss of an experienced CFO to a major joint venture is a notable shift.

🧠 The Analogy

Imagine a top-tier soccer team. The star striker (the outgoing CFO) isn't being cut—he's being transferred to a sister club in a different league to take on a new challenge. The team promotes its highly-regarded assistant coach (the new CFO) to the head role. The game plan doesn't suddenly change, but fans will watch closely to see how the new coach manages the offense.
