The whistleblowing channel provides a safe and confidential way to report concerns in good faith, ensuring that individuals can make reports without fear of retaliation. You can anonymously report behaviors that do not align with our values, helping us maintain a safe and healthy work environment.

Here's how to make a report:

A. Visit Visit contatoseguro.com.br/bostonmetal.
B. Call toll-free at 1 (800) 821-5902.
C. Or report it via WhatsApp, with complete protection of your information.

The Channel is managed by Contato Seguro, an independent and impartial company that receives reports with a guarantee of confidentiality. Therefore, the report is received by the outsourced company and then forwarded to our company to investigate, in accordance with the pre-established access levels.

Why does this matter?

• The person making the report has the security of anonymity, if they so wish.
• The report is received fairly and impartially by Contato Seguro.

How does it work in practice?

1. Contato Seguro receives your report.
2. Your IP address (the number that identifies your computer) is not shared, and calls are not traced, nor is the phone number for reports via WhatsApp.
3. The report is sent to our company to carry out the investigation.

To put it simply: imagine that you want to tell someone something very important, and you'd rather tell it to an outsider who doesn't know anyone in our company. That someone is Contato Seguro, which guarantees that your secret will be well-kept and fairly handled.

Always. If you opt for an anonymous report, Contato Seguro will register the report without your identity. If you opt to identify yourself, Contato Seguro will register your identity and the investigation team will be informed of it as well, but the information will still be kept confidential from any external parties other than the Risk & Compliance Department.

Remember:

• Confidentiality of information is guaranteed.
• You will be protected against any retaliation.
• Your phone number, WhatsApp information, or computer IP address will not be identified.

This strengthens Boston Metal's commitment to ethics, integrity, and the well-being of employees, promoting a safer, fairer, and more inclusive work environment.

You can and should report any behavior that violates our internal policies, especially the Code of Conduct, as well as legislation in force. Here are some examples of what can be reported through the Channel:

Not necessarily. A suspected violation, even without evidence, can also be reported, provided it is done so in good faith. Always try to include as much information as possible in your report so the team can address your report in the best manner.

• If you have any evidence, the system allows you to attach any type of file such as photos, videos, audios, etc.
• If it is over the phone, the psychologist who answers your call will explain how to send the evidence.

Contato Seguro manages receipt of reports by phone. It is a third-party company with a team of psychologists, ready to support you in the best possible way. These professionals have no connection with Boston Metal, and the complaint is received 100% confidentially.

• You run no risk of having your voice or situation identified, revealed, or leaked by anyone.
• Under no circumstances will our company or the team responsible for the investigation know who made the anonymous report through the Channel.

When you file a complaint, you receive a protocol number. This number is essential for tracking the progress of your report. Here's how to track your report:

• Visit the website contatoseguro.com.br/bostonmetal.
• Scroll down to the “Follow up on your report “ section.
• Enter your protocol number.
• Click on the arrow to move forward.

If the report was made by telephone, the specialist will inform you of the protocol. Write down the number so you can follow up later. The investigation team may request more information about the report through messages that can only be accessed through the protocol. Thus, please keep note of your protocol number!
