Even so, some hostile attitudes can happen, putting the company, you, and other colleagues at risk.

• That's why the Whistleblowing Channel exists! To protect everyone.

Through it, you can report, 100% anonymously, irregularities that do not comply with our values and the laws, helping us to maintain a safe and healthy work environment.

The Channel is third-party, managed by Contato Seguro, an independent and impartial company.

If you identify or are aware of any irregularities:

• Visit contatoseguro.com.br/timbrasil and make your report or call 0800 900 8007.

Based on your report, Contato Seguro will forward the information to an Ethics Committee, which will begin the investigation and deal with the report correctly. Measures will be taken only after the irregularity is verified.

• If you have any evidence, the system allows you to attach any file (such as photos, videos, audio, etc.).

The Channel helps us create and keep the company safer and free from irregularities, preventing and combating attitudes that could harm us all.

This results in an increasingly healthy, welcoming, transparent, and ethical work environment with more opportunities.

Contato Seguro has a team of psychologists ready to welcome you. These professionals have no relationship with us, and the receipt of the report is 100% confidential.

• You do not have any risk of having your voice or situation identified, revealed, or leaked by anyone.

• Under no circumstances will our company or the committee responsible for the investigation know who made the anonymous report through the Channel.

When making a report, a protocol will be generated. To track the progress, follow these steps:

1. Go to the website www.contatoseguro.com.br/timbrasil

2. Select the option “Check Answer”.

3. Enter the number. If the complaint was made over the phone, the specialist would inform the protocol number! Write down the number so you can track later.

It is possible that the committee requests more information about the report, through messages that can only be accessed through the protocol number.
