(stock abbreviation: Layn Biotechnology, code: 002166.SZ) had its Wind ESG rating upgraded from B to BB. The company's overall score is 5.84, slightly lower than the biotechnology III industry average of 6.37. It ranks 97th among 154 companies in the biotechnology III industry, placing it in the top 62.99% of the industry. The scores for environmental, social, and governance dimensions are 3.44, 3.55, and 5.72, respectively. Compared to the previous rating, the overall score increased from 4.70 to 5.84, an improvement of 1.14 points. The contribution from management practices rose from 2.27 to 2.93, an increase of 0.66 points. The contribution from controversy events increased from 2.43 to 2.90, an improvement of 0.47 points. In terms of dimensions, the environmental dimension improved by 1.81 points, the social dimension by 0.79 points, and the governance dimension by 0.87 points. ## Rating Observation In the environmental dimension, the company demonstrated a relatively complete waste management and climate change response capability, forming a comprehensive signal from management systems to performance disclosure. The company has obtained ISO 14001 environmental management system certification, integrated environmental protection requirements into daily operations, and established a refined waste classification management system, prioritizing waste reduction through production process optimization while strictly following the "National Hazardous Waste List" and entrusting qualified third-party organizations for resource reuse or harmless treatment. Regarding climate change, the company has built a three-tier climate governance structure composed of the board of directors, management, and production support department, incorporating climate response and carbon reduction efforts into long-term business planning. In 2025, the first phase of the photovoltaic project achieved energy savings of 5.68 million kilowatt-hours, equivalent to a reduction of 2,297 tons of carbon dioxide emissions, and disclosed total greenhouse gas emissions of 86,619.62 tons of carbon dioxide equivalent. The disclosure on energy issues is relatively limited, and there is still room for improvement regarding information on energy management goals and plans, as well as the proportion of renewable energy consumption. In the social dimension, the company has demonstrated strong organizational capabilities and performance in research and development, innovation, and employee development and training. The company has obtained high-tech enterprise certification and multiple specialized and innovative recognitions, established several research and development centers, and formed an innovation system covering the entire R&D process. In 2022, R&D investment reached 78.2142 million yuan, accounting for 3.83% of revenue, with R&D personnel making up 12.59% of the total workforce and a total of 109 effective patents. The company has also established systems such as the "Intellectual Property Management Measures," with the goal of further increasing the number of patents and the proportion of R&D personnel by 2025. In terms of employee development, the training coverage rate reached 100% for the year, with an average training duration of 6.5 hours per person, covering multiple modules such as management empowerment and safety production, and enhancing production line employee skills through skill competitions. Although there is some disclosure regarding supply chain and product quality management, there is still room for improvement in specific performance data such as the proportion of sustainably certified suppliers In terms of governance, the company demonstrates a strong structural checks and balances mechanism and a commitment to ESG governance. The proportion of independent directors on the board is 37.5%, and there are no independent directors whose tenure exceeds 6 years or 9 years, indicating a certain level of independence. The attendance rate of board members reaches 100%, with no member having an attendance rate below 75%. The company has established a three-tier ESG governance structure involving the board of directors, the management team, and various functional departments and subsidiaries, integrating ESG factors into its development strategy and risk management processes. However, the dual role of the CEO as chairman and the overlap of members of the compensation committee with executive members may pose a potential impact on the independence of compensation decisions. Additionally, the disclosure of specific working rules related to the board's diversity management system and ESG governance still needs improvement.
