Code of Conduct WALTER GROUP | Business Partners CoC Business Partners | October 2025 Page 10 of 10 5.1 Grievance Procedure The Business Partner is required to communicate, in an appropriate manner, the information provided by the WALTER GROUP regarding accessibility, responsibilities and implementation of the grievance procedure to its employees. The procedure must be easily accessible to all employees, preserve the confidentiality of their identity and provide effective protection against retaliation. It must also ensure that external stakeholders affected by potential impacts have access to the grievance mechanism. If the Business Partner does not receive separate instructions from the WALTER GROUP, it is required to establish an effective grievance mechanism at the operational level. This mechanism must be available to individuals and communities who may be affected by adverse impacts. All incoming complaints must be carefully examined, followed up and documented in a transparent and traceable manner. In addition, the WALTER GROUP provides its own whistleblowing platform through which reports may be submitted openly or anonymously: https://wltr.gp/whistleblower/ Should a breach of the provisions of this Code of Conduct be identified, the WALTER GROUP will grant the Business Partner a reasonable cure period to remedy the violation.
