Raw materials provided by suppliers are strictly verified to ensure their sources are compliant and not covered by the above list. Raising conservation awareness Across all business operations, the Group continuously strengthens internal publicity and training on biodiversity protection, enhancing the conservation awareness of employees and suppliers, and jointly fulfilling the biodiversity protection commitment. The United Laboratories' Commitment to Biodiversity Protection During the Year, Inner Mongolia Company organised systematic special training sessions focused on key areas such as hazardous waste standardised management, continuous emission monitoring system technical specifications, and environmental assessment mechanisms, comprehensively enhancing employees' environmental compliance awareness and professional operational capabilities. Through systematic learning, employees have become proficient in the whole-process control requirements for hazardous waste and online monitoring specifications, ensuring that exhaust gas monitoring data are authentic, accurate, and valid, thereby providing strong support for stable pollutant discharge compliance. This training has further reinforced environmental responsibilities, improved internal assessment and supervision mechanisms, effectively enhanced environmental risk prevention and control capabilities, and raised the overall level of environmental management, laying a solid foundation for the Company's green and sustainable development. 51 Strengthening environmental capabilities and building a solid compliance management defence line The United Laboratories International Holdings Limited 2025 Environmental, Social and Governance Report
