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 aims to establish enduring partnerships with its suppliers on the basis of mutual benefits and trust, thus fostering robust business relationships. In a constantly evolving world, the collaboration of its suppliers is crucial for the company to effectively address market demands. In this respect, Cellnex regularly updates its suppliers on new projects and encourages their cooperation. It is essential for the company to ensure that its suppliers are aware of its corporate policies and values, and that compliance with all of them is enforced. This collaborative approach ensures that Cellnex's supplier relationships are mutually beneficial and focused on long-term success, while also managing any potential risks.

The procurement process is key for Cellnex. For this reason, the company has established and actively promotes an action guide for the procurement process that goes beyond price, product and/or service quality, but that also considers social, ethical, environmental, and privacy aspects regarding the performance of its suppliers. This reflects the company's proactive approach to managing its supply chain impacts and risks in line with sustainability principles. By integrating these factors into procurement practices, Cellnex ensures that its supplier base contributes positively to its broader ESG objectives.

The company's supplier relationship model relies on a collaborative approach between the requesting departments and the procurement team, working jointly to achieve optimal procurement practices. In many cases, relationships with suppliers are built upon years of cooperation between Cellnex staff and its suppliers. This model of collaboration reflects the company's long-term approach to managing supplier relationships, ensuring that risks are mitigated and mutual benefits are prioritised.

Through this close partnership, Cellnex is better positioned to address challenges and opportunities, enhancing both supplier performance and business outcomes.

The company also prioritises a collaborative approach to supplier management when focusing on efficiency and innovation. By implementing a Sustainability Linked Confirming, tied to CDP scores, Cellnex incentives sustainable practices among its suppliers.

This initiative is not only aligned with the company's ESG objectives, but also fosters long-term, value-driven partnerships.
