(stock abbreviation: SigmaStar Technology, code: 301536.SZ) had its Wind ESG rating upgraded from B to A. The company's overall score is 7.43, higher than the semiconductor product industry average of 6.07. It ranks 30th among 146 companies in the semiconductor product industry, placing it in the top 20.55% of the industry. The scores for the environmental, social, and governance dimensions are 5.11, 6.36, and 7.06, respectively. Compared to the previous rating, the overall score increased from 4.97 to 7.43, an improvement of 2.46 points. Among these, the score for management practices rose from 2.02 to 4.43, contributing 2.41 points to the increase; the score for controversial events remained stable at 3.00. In terms of dimensions, the environmental score improved by 5.11 points, the social score increased by 3.30 points, and the governance score rose by 2.68 points. ## Rating Observation In the environmental dimension, the company demonstrated comprehensive climate change management capabilities, with disclosures ranging from management system construction to performance quantification. The company has integrated climate change into its sustainable development management system, with an ESG leadership team overseeing greenhouse gas emissions, energy-saving measures, and climate risk assessments, and quantifying climate risks through scenario analysis methods. The carbon emission target for 2026 is set to not exceed the levels of 2025. In 2022, the company's total greenhouse gas emissions amounted to 2,848.59 tons of CO2 equivalent, with scope 1 and scope 2 emissions being 68.52 tons and 2,780.07 tons, respectively. In terms of energy management, the Xiamen main data center optimized energy consumption structure through hot and cold air flow management and high-efficiency equipment scheduling, maintaining a PUE of less than 1.5 throughout the year, saving approximately 87,500 kWh of energy annually. Additionally, the company's total energy consumption was 644.17 tons of standard coal, with energy consumption per million revenue at 0.2167 tons of standard coal/CNY, reflecting quantified energy usage efficiency. However, the information disclosure in the area of water resource management is relatively brief, lacking detailed data on key indicators. In the social dimension, the company demonstrated strong organizational capabilities and performance results in research and development, as well as occupational health and safety production. The company has established a systematic R&D management system through the "R&D Management System," with board members responsible for R&D work, and the R&D center overseeing system construction, project management, and budget supervision. R&D investment accounts for 21.94% of revenue, with the proportion of R&D employees reaching 75.41%. The total number of effective patents is 70, with an effective patent count of 2.36 per hundred million revenue, indicating a high level of technological innovation capability. In terms of occupational health and safety production, the company achieved zero work-related deaths and zero major accidents, with an injury rate of only 0.23%, and enhanced employee safety awareness and emergency capabilities through regular training and emergency drills. Furthermore, the company has some disclosures regarding employment, supply chain management, and employee development and training, but the management goals and planning information in the areas of occupational health and R&D still need further improvement In terms of governance, the company demonstrates a strong system of checks and balances and certain signals of diversification. The proportion of independent directors reaches 44.44%, with 100% of the audit committee being independent directors, and there are no independent directors whose tenure exceeds 6 years or 9 years. The attendance rate of board members is 100%, with no members having an attendance rate below 75%, indicating a high level of meeting participation. However, the company's CEO also serves as the chairman, and there is overlap between the members of the compensation committee and the executives, which may pose challenges to governance independence. The proportion of female directors is 22.22%, but the proportion of female executives is 0%, reflecting a lack of gender diversity. Although the company performs well in terms of audit committee independence and board participation, additional information disclosure regarding the effectiveness assessment of the board and the committee responsible for risk management is still needed.
