Cellnex adopts a zero-tolerance policy for retaliation. The company safeguards whistleblowers by ensuring that no individual who reports concerns in good faith will face retaliation. If any whistleblower perceives that they have been subjected to retaliation, they are encouraged to report this immediately, and the company will take appropriate action to investigate and address the issue. All whistleblowers are guaranteed confidentiality and protection in line with applicable laws, including the EU Whistleblower Directive (2019/1937).

Outcomes from investigations conducted by the CEC or arising from reports submitted via the Whistleblowing Channel are communicated to the appropriate administrative, management and supervisory bodies, in accordance with internal procedures. The Policy for the Whistleblowing Channel and the Anti-Bribery, Gifts and Hospitality Policy define the process for reporting these outcomes, ensuring that findings are shared with relevant governance structures for review and action, as appropriate. This ensures transparency and accountability at all levels of the organisation.
