Cellnex’s Whistleblowing Channel allows both internal and external stakeholders, including any third party, wishing to report concerns about unlawful behaviour or infringements that disobey the current legislation and/or other internal regulations within the company. The reporting mechanisms are accessible via multiple channels, including the Cellnex Intranet, email, mailing address and telephone, ensuring that individuals can easily raise concerns from anywhere in the world. The Whistleblowing Channel is managed by an independent expert third party, PricewaterhouseCoopers (PwC), acting as Channel Manager and ensuring confidentiality and impartiality of the process. The Channel Manager receives the initial communication and guarantees that it is transferred to the Committee of Ethics and Compliance (CEC) in due time. The CEC as the decision-making body, will investigate and adopt a final resolution that closes the procedure. The Channel Manager will then be responsible for communicating the resolution to the whistleblower in due time and form. To promote the use of the Channel, Cellnex has implemented extensive training, communication and awareness initiatives. These efforts ensure that all employees are fully informed about the existence, purpose, and proper use of the Whistleblowing Channel. In addition, employees receive training on the process of submitting communications and on the importance of raising ethical issues promptly. The commitment to training extends to the staff receiving the reports, who are prepared to handle concerns professionally, following legal guidelines and internal protocols.

Cellnex identifies activities and functions that are especially exposed to bribery and corruption risks through regular risk assessments. Based on these, the company implements targeted training programmes, apply strict controls, and conduct frequent reviews to manage these risks effectively. This approach ensures that the areas that are especially vulnerable to unethical conducts are continuously monitored, and that proper preventive measures are in place to mitigate potential issues related to bribery and corruption.
